Adjusting TIN-Related Problems Overview

  1. This section provides information on the following problems relating to taxpayer identification numbers (TINs):

    • Resequencing Accounts

    • Multiple Individuals Using the Same TIN

    • Mixed Entity

    • Streamline Identity Theft Case Processing (CAT 7)

    • Non-Streamline Identity Theft Case Processing

    • Scrambled Social Security Numbers (SSN)

    • True Scrambled Social Security Numbers (SSN)

    • No Merge (NOMRG)

    • Reversed Validity (REVAL) Transcripts

  2. Procedures in this section address all TIN types unless otherwise indicated. TIN types and their corresponding IDRS numeric formats are:

    • Social security number (SSN) entered in NNN-NN-NNNN format

    • Individual tax identification number (ITIN) entered in 9NN-NN-NNNN format

    • Internal Revenue Service number (IRSN) entered in 9NN-NN-NNNN* format. See IRM 3.11.3.9.2.1, Taxpayer Identification Number (TIN) for the valid 4th and 5th digit ranges for an ITIN or IRSN.

  3. TIN information for SSNs and ITINs may be posted on the valid or invalid segment of Master File. IRSNs are temporary numbers issued by the IRS and are always on the invalid segment of Master File. The invalid segment is indicated by an asterisk (*) following the last digit of the TIN. It is necessary to address both the valid and invalid segments of Master File when adjusting TIN related problems.

  4. When resolving TIN related problems, you may also need to refer to IRM 3.13.5, Individual Master File (IMF) Account Numbers, and IRM 3.21.263, IRS Individual Taxpayer Identification Number (ITIN) Real Time System (RTS).

21.6.2.2  (10-01-2007)
What Are TIN-Related Problems?

  1. TIN-related problems involve the TIN used on a taxpayer's account. Actions may be required on the Entity and/or tax module to correct TIN-related problems.

21.6.2.3  (10-01-2012)
TIN-Related Problems Research

  1. In order to correct TIN-related problems, you must be familiar with the following research elements:

    • Entity module

    • Transaction codes

    • Retention register - Request a retention register transcript only if the account cannot be reactivated by using command code IMFOL with definer "B."

    • Command codes, including NAMES, INOLE, DDBKD, DUPOL, MFTRA, IMFOL, RTVUE, FFINQ, REINF, with various definers

    • NUMIDENT (for SSN research only)

  2. The research necessary for accurately processing a TIN-related problem case includes, where applicable, and is not limited to the following:

    • Utilizing the Correspondence Imaging System (CIS) and all applicable and available internal research systems to review all related cases, whether open or closed

    • Utilizing CIS to review all related documents and/or attachments

    • Utilizing the ITIN Real Time System (RTS) to research and review data related to assigned, suspended and/or rejected Form W-7, Application for IRS Individual Taxpayer Identification Number. RTS is a tool located within the Employee User Portal (EUP), and Online 5081 permission and access are required. See IRM 3.13.5.81.7, Accessing the ITIN Real Time System (RTS) , and IRM 3.21.263.8, General Instructions for ITIN Navigation (ITIN RTS) for additional information.

      Note:

      The Form W-7 application's Document Locator Number (DLN) is only available on RTS

    • Number of years the TIN has been used for filing returns
      Filing status changes
      Method of filing, electronic or paper
      Previous adjustments
      Filing dates of original and duplicate returns
      TC 971 Transaction Codes

    • Utilizing NAMES to identify and locate all related TINs for all tax years

    • Utilizing RTVUE to determine items of information such as:
      Address for the first return(s) filed
      Dependents
      Type of income
      Filing Status
      Schedules and Forms filed

    • Utilizing TRDBV to determine items of information such as:
      Wage information details
      Occupation
      Tax Preparer
      Requested method of disbursing overpayment, electronic or by mail

    • Utilizing INOLE to determine items of information such as:
      Date of birth
      Previous names
      Spouse's TIN
      Other related TINs

    • Utilizing IRPTR to perform research actions and determine items of information such as:
      Comparative review of reported income and payor information
      Previous and current employers
      Previous addresses

    When working ITIN cases, you must research under the relevant SSN used for income reporting.

  3. Do not determine the validity of a social security card on the basis of the word "VOID" on the photocopy. Placing the word "VOID" on a photocopy of a recently issued social security card simply indicates that the document is a photocopy of the original card.

21.6.2.4  (10-01-2005)
TIN-Related Problems Procedures

  1. To correct TIN-related problems, apply the following TIN-related procedures.

21.6.2.4.1  (03-08-2010)
Resequencing Accounts

  1. When an account moves from one TIN to another or from one segment of a TIN (valid or invalid) to the other segment, it is called resequencing or merging.

    Note:

    If a taxpayer has tax modules under more than one TIN, the accounts need to be consolidated under one unique TIN. Follow instructions in IRM 21.6.2.4.1.3, Resequencing Action Required, to research for conditions that would prevent a merge. If none are found, merge the accounts with an entity transaction. If conditions are present that would prevent a merge, follow instructions in IRM 21.6.2.4.4, No Merge (NOMRG) Procedures, to consolidate the accounts by moving the modules individually. For ITINs, also refer to IRM 21.6.2.4.1.1, Resequencing Methods Procedures .

  2. The following entity transaction codes (TC) apply to resequencing accounts:

    TC Input to change
    011 TIN on a Master File (MF) account or to consolidate two accounts. This transaction is systemically compared against the DM-1 data file.
    013 Name on a MF account. This transaction is systemically compared against the DM-1 data file.
    040 TIN or name on an account which is on the valid segment of MF. It is not systemically compared against the DM-1 data file.
    041 TIN or name on an account which is on the invalid segment. It is not systemically compared against the DM-1 data file.

    Note:

    TC 040 is input only on the valid segment. Use this code when it is necessary to bypass DM-1 data tape validation. TC 041 is input only on the invalid segment. When resequencing the invalid segment of a TIN this code must be used; if not, the computer may erroneously move both the valid and invalid segment of the TIN.

21.6.2.4.1.1  (03-29-2013)
Resequencing Methods Procedures

  1. Resequencing on the Individual Master File (IMF) is often involved with the validity of a TIN.

    1. Each person may have only one TIN.

    2. Once a number is assigned, it cannot be assigned to someone else. A SSN is never "recycled" or reused.

    3. A transposition error in a TIN or name change, without notification to the Social Security Administration (SSA), may cause a TIN mismatch with IRS records. This is referred to as an "invalid" condition.

    4. The computer cross references all TINs to the SSA data and identifies these invalid conditions.

  2. Resequencing accounts is accomplished by one of two methods:

    • Automatic resequencing

    • Input of an entity transaction

  3. When resequencing an Individual Taxpayer Identification Number (ITIN), see IRM 3.21.263.7.4, Merges Involving ITIN, for information on the revocation of an ITIN and for processing steps. In addition to the steps listed in IRM 3.21.263.7.4, Merges Involving ITIN take the following steps prior to routing or faxing the Form 4442 to the Submission Processing Center (SPC) ITIN Unit:

    1. Ensure the resequence transaction has been input and monitor the module until the merge is complete.

    2. Close your CIS and IDRS case.

    3. Establish a new control on IDRS. For monitoring purposes, using the CSR number..

      Note:

      Use the ITIN Real Time System (RTS) to review the status of revocation.

      Note:

      The new control must be established manually. The Correspondence Imaging System (CIS) will not automatically open the new control.



      Use case status "M" .

      Use an activity code that begins with "ITRVK" .

      Use category code "MISC" .

      Use the current date as the received date.

    4. Route the 4442 to the SPC ITIN Unit and close the "MISC" case when the resequence has posted.

    Note:

    Any transfers of refunds, credits, or TC 400 must be completed and posted on the ITIN before requesting the revocation, or they may unpost.

21.6.2.4.1.2  (10-01-2006)
Determining Validity

  1. If the primary TIN and name control (NC) do not match (invalid), they are identified by an asterisk after the TIN. On joint returns, the spouse's TIN is preceded by a "1" if the TIN is invalid.

  2. On IMF Retention Register Microfilm transcripts, the computer assigns a validity digit of "0" when TIN and NC match (valid). A validity digit of "1" is assigned when TIN and NC do not match.

  3. When the DM-1 data tape file is received, it is systemically compared to the invalid segment of MF.

    1. Any change in an account's validity causes a resequence under TC 001 and generates a Document Locator Number (DLN) of 00200–000–00006–9.

    2. A residual record is maintained on the invalid segment after an account is resequenced.

    3. The TIN slot is reserved until released by a returning memo record (TC 026) or the account fails to merge.

  4. Resequencing created by entity transactions is accomplished by a name change (TC 013) or a TIN change (TC 011) to MF.

    Note:

    These accounts are compared to DM-1 data and matched on TIN and NC.

    1. A residual record is maintained on the "from" segment after the account is resequenced.

    2. The TIN slot is reserved until released by a returning memo record (TC 026) or account fails to merge.

  5. Resequenced accounts which fail to merge, return to their original validity slots.

    1. Memo transactions (TC 026), resequencing to release the hold on residual account slots, are directed to the valid segment of MF from which the originating account came without regard to a match with SSA data.

    2. When accounts do not merge, a transcript generates for both accounts involved and the TC 026 transaction does not post.

    Note:

    If the accounts fail to merge when DLN of 00200–000–00006–9 generates, the computer no longer recognizes the invalid segment. Adjustments made to the invalid TIN automatically post to the valid TIN. An Internal Revenue Service Number (IRSN) must be obtained and the valid or invalid TIN is moved to the IRSN. See IRM 21.4.6.5.25.1,UPC 134.

21.6.2.4.1.3  (10-01-2013)
Resequencing Action Required

  1. Action required:

    1. Research IMFOL for the valid and invalid accounts for both TINs (the "to" and "from" TINs) prior to resequencing an account. The resequencing action moves all tax periods present in the account. Specific tax periods cannot be moved independently. Research for open NMRG controls on ENMOD or SUMRY. This should be done to avoid resequencing or merging a case in progress.

    2. Reinstate all lower level modules using Command Code (CC) IMFOLB. Reinstate any vestigial module that could prevent a successful merge by preparing Form 5248, Transfer Request. Form 3774, Request for Research, or CC ESTABM are two of the options available if microfilm research is necessary. See IRM 21.5.2.4.13,Reinstating Retention Register Accounts and IRM 21.2.2.5.10, Requester Responsibilities.

    3. Use caution when moving accounts. Improper attempts to resequence accounts when a no merge condition is present causes a no merge (NOMRG) transcript to generate.

    Caution:

    Resequencing an account to a valid TIN or to an IRSN, even if the attempt fails, can release an overpayment not held with a TC 570 or TC 576 on any active module under the TIN being moved. An I- freeze only holds credit interest. It does not hold the credit. Reminder: A TC 570 cannot post to an invalid account where the DLN 00200-000-00006-9 has posted. Other methods must be used to hold the credit. Open a control with the activity “HOLDREFUND” so that Notice Review will stop the refund.

    Note:

    For merges involving ITINs see IRM 21.6.2.4.1.1, Resequencing Methods Procedures.

    Note:

    See IRM 3.13.5.81.11 , ITIN Merge Procedures (ITIN to SSN merges) with Mismatching Name Controls, if applicable.

  2. DO NOT MERGE accounts if:

    • You have not received the prerequisite training to resolve the case

    • The name control of the "from" account does not match the name control of the "to" account

    Note:

    For Telephone Assistors and Taxpayer Assistance Centers (TAC) employees who have not received the requisite training, refer Merges/Resequences involving extensive research to the appropriate area using Form 4442/e-4442, Inquiry Referral. See IRM 21.6.2.4.1.4, Reassignment of NOMRG Cases due to Site Specialization, for guidelines on determining the appropriate referral area.

    • Two taxpayers are involved (e.g., husband and wife, parent and child, sister and brother, two totally different people etc.).

    • A TC 150 for the same year is posted on both accounts.

    • Either account contains a vestigial record (removal of modules to Retention Register) for which there is an active tax module or for a vestigial record with the same tax period in the other account.

    • Either account contains an unreversed TC 914, 916, or 918 (Z Freeze).

    • Either account contains a module with an unreversed TC 400 and there is a module for the same tax period in the other account (M- Freeze).

    • One account contains a module with an unreversed TC 576 and the other account contains a module for the same tax period which either contains an unreversed TC 570 or is in a debit balance status. (This is usually a -Q or -R Freeze)

    • Either account contains Mail Filing Requirement (MFR) 08 and Scramble Indicator (SCI) 01, 10, 12, 13, 20 or 23.

    • Both accounts contain a module in Taxpayer Delinquency Investigation (TDI) Status 03 (indicator other than 08) or Taxpayer Delinquency Account (TDA) Status 22, 24, 26, or 60, and the Primary or Collection Location Codes are not in agreement (-T Freeze).

    • Both accounts contain a module for same tax year and the resulting merge would cause more than 52 TCs 766, document code 54, blocking series 400-499 to be posted in the accounts.

    • One or more accounts contain a revoked ITIN, (verify on EUP/RTS).

    • Both accounts contain a module for the same tax period with an unreversed TC 520 (except closing codes 81 or 85-88) (-V Freeze).

    • Both accounts contain an unreversed TC 810 for the same tax period (-E Freeze).

    • The "from" account contains a civil penalty name line which does not match the name control of the "to" account.

    • The name control of the "from" account does not match the name control of the "to" account.

    • Both accounts contain an unreversed TC 930 or 424 on the same tax period or one account contains an unreversed TC 930 and the other account contains an unreversed TC 424.

    • The "from" account contains a TC 896 or TC 898 within 6 years of the original offset date. See IRM 21.4.6.5.21,Re-sequence Cases.

      Caution:

      If TC 898/896 cannot be reversed on an invalid TIN. IRM 21.6.2.4.4.12, NOMRG-896/898, for instructions to follow if the offset is on an invalid TIN.

    • Both the From and To accounts contain non-zero First Time Homebuyer Credit amounts for the primary taxpayer.

    • Both the From and To accounts contain non-zero First Time Homebuyer Credit amounts for the secondary taxpayer.

    • For Master File Transaction (MFT 55), both modules contain an unreversed TC 608.

    • DO NOT merge Individual Retirement Accounts (IRA) accounts.

    Note:

    Accounts that cannot be merged must be resolved using No Merge procedures. See IRM 21.6.2.4.1.4, Reassignment of NOMRG Cases due to Site Specialization IRM 21.6.2.4.4, No Merge (NOMRG) Procedures.

21.6.2.4.1.4  (10-01-2013)
Reassignment of NOMRG Cases due to Site Specialization

  1. Cases involving merge issues are worked by the designated specialized sites. There are two types of cases involving merge issues:

    • Failed merge attempt, i.e., cases that generate a NOMRG or REVAL transcript.

    • Potential NOMRG cases identified prior to any attempted merge.

  2. The reassignment to the holding number, 0830141335, is performed systemically for cases that generate a NOMRG or REVAL transcript.

  3. The reassignment of potential NOMRG cases to the holding number, 0830141335, is performed manually.

    Note:

    Prior to sending the case to the holding number, you will need to notate the no-merge condition in the case message on CIS or the Form 4442, update the doc type to No Merge, the category to NMRG, and the program code to 710–40053.


    Note:

    If you determine that the case should be assigned to the holding number, 0830141335, and you have no other option other than referring the case using Form 4442/e-4442, fax the Form 4442 to the Inventory Control Manager (ICM) at Andover. The fax number is ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ (for internal use only). Address the Fax to "Andover ICM" , and in the notes section of the fax cover sheet indicate "NOMRG/Potential NOMRG" .

    Caution:

    If a case is reassigned to the No-Merge unit that does not meet the no-merge criteria, the case will be rejected back to the originator. The no-merge employee will annotate the reason for the rejection on AMS.

21.6.2.4.2  (10-01-2013)
Multiple Individuals Using the Same TIN

  1. Cases involving multiple taxpayers using the same Taxpayer Identification Number (TIN) are classified generally as mixed entity, identity theft cases, Scrambled SSN cases, or True Scrambled SSN cases. Preliminary research must be completed before the case can be accurately identified. Normally, these conditions are identified while working Computer Paragraph (CP) 36, Duplicate/Amended Filing Condition transcripts.

    Note:

    Do not change the category code to "MXEN" , "IDT1" , "IDT3" , "SCRM" , or "SSA2" unless specifically instructed to do so by this IRM.

  2. A mixed entity case is the general designation for a case involving the filing of a tax return by an individual who is using a Taxpayer Identification Number (TIN) belonging to another individual. Typically, a mixed entity case involves the filing of returns by both the owner of the TIN and by the non-owner of the TIN.
    In some cases, the erroneous use of the TIN is due to an inadvertent taxpayer or tax preparer error, or a processing error. For inadvertent or processing error cases, the valid TIN of the taxpayer using the incorrect TIN can often be located. Cases in which the erroneous use of the TIN is due to an inadvertent or processing error will have the category code "MXEN" and will be worked under the 710-40054 function and program.
    In many cases, however, the erroneous use of the TIN is not a processing error and does not appear to be inadvertent. For these cases a valid TIN for the taxpayer using the incorrect TIN usually cannot be located. The account information for the taxpayer using the incorrect TIN is moved to an Internal Revenue Service Number (IRSN) or the return is nullified. Cases in which the erroneous use of the TIN is NOT due to an inadvertent or processing error will have the category code "IDT1" , or the category code "IDT3" etc., and will be worked under the 710-40011 function and program. (Please see 2nd table below for TIN-Related Problem Codes.)

    Note:


    Procedures identified in this IRM as "mixed entity" procedures are applicable to all six categories. The defining characteristics of the six categories are shown in the following table:

    TIN-Related Problem Case Types
    Category Code Defining Characteristic
    MXEN Involves an inadvertent or processing error
    MXSP Involves a Spanish inadvertent or processing error
    IDT1 Involves taxpayer identified identity theft
    IDS1 Involves Spanish taxpayer identified identity theft
    IDT3 Involves IRS identified identity theft
    IDS3 Involves Spanish IRS identified identity theft
    IDT6 Involves Electronic Fraud Detection System (EFDS) cases for either taxpayer , or IRS identified identity theft cases
    IDT8 CP05A cases with prior IVO involvement or Deceased Taxpayer cases ONLY
    IDT9 Involves an Identity Theft Assistance Request (ITAR)
    IDS9 Involves a Spanish Identity Theft Assistance Request (ITAR)

    Any mixed entity case that does not involve an inadvertent/processing error is considered, for our purposes, an identity theft case. The category codes reflect this distinction. The category codes further make a distinction between those cases that have no documentation indicating or supporting identity theft from the determined owner of the TIN and those cases that have such documentation.


    Note:

    The following table shows the applicable codes for a mixed entity case and an identity theft case:

    TIN-Related Problem Codes
    Category Code CIS Document Type CIS Program Code Function and Program for Time Reporting
    MXEN/MXSP Duplicate Filing 40054 710–40054
    IDT1/IDS1 ID Theft 40011 710–40011
    IDT3/IDS3 ID Theft 40011 710–40011
    IDT6 ID Theft 40016 710-40016
    IDT8 ID Theft 40017 710-40017
    IDT9/IDS9 ID Theft 40019 710-40019
    SCRM Duplicate Filing 40052 710–40052
    SSA2 Duplicate Filing 40052 710–40052


    Note:

    This IRM often refers to the "common number" or "CN" . The CN is the taxpayer identification number (TIN) being used by both taxpayers.

  3. A mixed entity case may need to go through the scrambling process. While it is going through this process it is categorized as "SCRM " . See IRM 21.6.2.4.3, Scrambled SSN Case Procedures. The utilization of this process, however, should be rare. This IRM provides guidelines for determining who the owner of the CN is when such determination is needed. The determination is not needed, and should not be made, when the case is a True Scrambled SSN case (see below). For all cases other than True Scrambled SSN cases, the guidelines in this IRM provide sufficient guidance on determining ownership of the CN, and thereby avoiding the scrambling process. There are rare exceptions, and this IRM provides stringent guidelines for determining when a case other than a True Scrambled SSN case should go through the scrambling process.

    Note:

    An ITIN CN will never create a scrambled SSN case. ITIN cases will follow the remaining procedures in this section to determine ownership, before using Mixed Entity procedures.

  4. A True Scrambled SSN case occurs when the Social Security Administration (SSA) assigns the same SSN to more than one taxpayer. This may be validated during preliminary research of NUMIDENT (MFTRA type "U" ). NUMIDENT may reflect SSA assignment of the SSN to multiple individuals.

    • A True Scrambled SSN case requires communication with SSA for resolution.

    • All research steps in this IRM will be performed for True Scrambled SSN cases. This includes the procedures followed for the primary purpose of determining ownership of the CN, e.g., making telephonic contact with the taxpayer as instructed in IRM 21.6.2.4.2.12.1, Sending the Letter 239C and Telephone Contact-Stage One. This will be done in order to provide SSA with as much information as we can obtain.

    • The research steps will be completed, but at no time will following the procedures in this IRM result in the IRS making a determination of CN ownership for a True Scrambled SSN case. Only the SSA can resolve True Scrambled SSN cases.

    • If research determines that the same ITIN was assigned to more than one individual, a determination of ownership will be made using the Pre-Letter 239C procedures. These cases will never be sent to SSA.

  5. A TIN-Related Problem Secondary case occurs when one or both of the taxpayers using the CN is the secondary taxpayer on a joint return.

    TIN-Related Problem Secondary cases will be processed following the general guidelines of this IRM. All relevant procedures will be followed to determine the true owner of the TIN (CN). If all means of determining ownership as provided in this IRM have been exhausted, and a determination of ownership still cannot be made, applicable Scrambled SSN procedures will be followed with the addition of the following:

    • Place the scrambled indicator on the entity of the secondary spouse's TIN (the CN) as well as the IRSNs. The scrambled indicator is input on the CN and IRSNs only.

    • Update the joint name lines on a joint account where the CN is being used as a secondary TIN to replace the CN with the assigned IRSN.

    • Input TC 971 action code (AC) 017 on the IRSN to cross-reference the primary TIN on the joint account.

    • Follow erroneous refund procedures under the joint account if any credits that require a valid TIN were previously allowed and resulted in a refund.

      Note:

      A determination will always be made for an ITIN case.



    TIN-Related Problem Secondary cases will not always occur for the same tax period.

    Example:

    An individual has filed as the secondary taxpayer for a number of years using a TIN. Another individual, who has not had a filing requirement for a number of years, now files as Single on a current year return using the same TIN.



    Many of these cases will originate as refund inquiries in which, using the above example, the overpayment of the Single taxpayer is offset to a debt on the joint account for the secondary filer for a previous tax year. Cases such as this example provide an "indication" of Identity Theft. Consequently, the Identity Theft procedures in this IRM would be applicable. See IRM 21.6.2.4.2.2, Taxpayer Inquiries Involving Questionable Ownership of a Primary or Secondary TIN on a Filed Return.

  6. An Examination Multiple Filer case is created when the same Taxpayer Identification Number (TIN) appears as a primary TIN on one account and as a secondary TIN on another account for the same tax period. Examination reviews multiple filer cases and sends those involving two or more taxpayers to the Entity function. (For our purposes, this type of case can also be categorized as a TIN-Related Problem Secondary case. See paragraph "6" above for additional information on TIN-Related Problem Secondary cases.) Entity corresponds with all taxpayers requesting verification of their TINs. The resolution is coordinated with AM, using mixed entity or scrambled SSN case procedures, if the Entity function does not locate a different valid TIN for all taxpayers. See IRM 3.13.5.11, Secondary Taxpayer Invalid SSN . See also IRM 21.6.7.4.5, Multiple Uses of Taxpayer Identification Numbers - CP 36F.

    Note:

    DO NOT scramble ITIN cases.

  7. Route cases with a Z freeze to the Scheme Development Center (SDC). For cases with a P- Freeze with category code PFRZ, refer to IRM 21.5.6.4.31, P- Freeze for additional guidance. Take no action unless the Z freeze is released. If the Z - freeze is released, follow mixed entity or scrambled SSN case procedures. See IRM 21.6.2.4.2.4 Mixed Entity Procedures for established mixed entity procedures. See IRM 21.6.2.4.3 Scrambled SSN Case Procedures, for established scrambled SSN procedures.

    Caution:

    Do not follow SDC instructions which deviate from established procedures. Established procedures do not permit SDC determinations of the CN owner.

  8. Refer to the SDC, any "leads" related to alleged stolen identity accounts, data that may lead to a fraudulent filing of tax returns for the purpose of gaining false or inflated refunds, or potential Electronic Return Originators (ERO) schemes, etc. Do not refer the case. Continue to work the case. Use Form 4442 to provide the following information:

    1. TIN(s) and tax year(s) involved

    2. Brief description (e.g., alleged stolen identity). Notate that the Form 4442 is a "Lead Only."

    3. Copy of the source of allegation (e.g., copy of taxpayer correspondence), if available

    4. Copy or Correspondence Imaging System (CIS) print of the paper return (if a subsequent paper return was filed and taxpayer(s) are alleging stolen identity)

    Note:

    Fax numbers for CI SDC can be found by selecting F-4442/(e-4442) Referral Fax Numbers, under the Who/Where tab on the SERP Home Page. These numbers are for internal use only. Never give these numbers to the taxpayer.

21.6.2.4.2.1  (10-01-2013)
Telephone Inquiries Regarding MXEN, MXSP, IDT1, IDS1, IDT3, IDS3, IDT6, IDT8, IDT9, IDS9, and Scrambled Cases

  1. A mixed entity case or identity theft case controlled on IDRS can be identified by control categories, "MXEN" "IDT1" , "IDS1" "IDT3" , "IDS3" , "IDT6" , "IDT8" , "IDT9" , "IDS9" , or "SCRM or SSA2" . Unless an exception in paragraph (2) applies, telephone CSRs must not make adjustments on open controlled mixed entity, identity theft or Scrambled SSN accounts. This includes but is not limited to the items in (a) thru (f) below.

    1. Do not input an address change on the account(s). Notate both the old and new address on Form 4442.

    2. Do not release overpayment(s) held on the account(s).

    3. Do not attempt to resequence the account(s).

    4. Do not attempt to unscramble the account(s).

    5. Do not input adjustments.

    6. Do not release freeze conditions on the account.


  2. The following exceptions apply to paragraph (1) above.

    1. For inquiries related to transcripts, see IRM 21.2.3.4.1.3,Transcripts and Identity Theft.

    2. For balance due accounts, verify high risk disclosure and continue to assist customer with account information (i.e. establishing IA, revising IA, providing balance due information and updating the address of record if necessary). An address change may be necessary to ensure the taxpayer receives their balance due notices and/or reminder notices. For additional information, see IRM 21.3.12.6.10, Balance Due Accounts Involving Identity Theft.

    3. For current year returns, If a taxpayer loses or misplaces an IP PIN, the IRS may provide a replacement IP PIN. See IRM 10.5.3.2.16.1, Lost, Misplaced or Non-Receipt of IP PIN, for additional guidance.

    4. For AGI or Self Select Pin inquiries, see IRM 21.2.1.40.1, E-file 1040 Series Online Filing with Prior Year Identity Theft, when the caller is attempting to obtain his/her prior year AGI or Self Select PIN, and the account contains an identity theft indicator.

  3. If a Letter 239C has been sent, and the taxpayer has not responded, advise the taxpayer to complete the Letter 239C questionnaire and return it with all of the documentation requested. See IRM 21.6.2.4.3.5, Determining if the Refund Should be Released, for documentation requested in the Letter 239C. Refunds will be held until a complete Letter 239C response is received.

    Note:

    Do not release refunds on accounts which are controlled on IDRS with the following categories, "IDT1" , "IDS1" , "IDT3" , "IDS3" , "IDT6" , "IDS6" , "IDT9," "IDS9" , or "SCRM/SSA2" If the taxpayer is claiming a hardship, which may warrant the issuance of a manual refund, refer the case to the Taxpayer Advocate Service (TAS) for hardship determination per IRM 21.4.4.2, Why Would A Manual Refund Be Needed?


  4. If the case is closed/resolved, you may provide account information to the TIN owner utilizing normal procedures. You may only provide the TIN owner with the information from his/her account only. Do not provide information from the fraudulent return, except for the prior year AGI and/or PIN as discussed in the fourth exception above. You can identify the following transaction(s) on IDRS via cc ENMOD and/or cc IMFOLE, if the case has been resolved.

    • A posted or pending TC 971 AC 501 or

    • A posted or pending TC 971 AC 506

    Additionally, for a closed IDT case, if the SSN owner did not receive their refund, received an incorrect refund amount, or an incorrect balance due notice because the case was worked incorrectly, (i.e. the CSR failed to input the TC 971 AC 850 causing a second direct deposit into the bad taxpayer's account), treat the case as priority work and take the following actions:

    IF THEN
    The case can be resolved over the telephone, see IRM 21.1.3.20,Oral Statement Authority and IRM 21.5.2.4.2,Adjustments with Oral Statement. Input the account adjustment.
    The case cannot be resolved over the phone and the case meets TAS criteria, see IRM 13.1.7.2,TAS Case Criteria. Follow IRM 21.1.3.18,Taxpayer Advocate Services Guidelines to complete a referral.
    The case cannot be resolved over the telephone and the case does not meet TAS criteria. Complete a Form 4442 and fax to the specific area based on the IDRS number/site in the Form 4442 referral chart below.

    ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡

  5. On open cases, regardless of the result of the disclosure probes performed in IRM 21.1.3.2.3, Required Taxpayer Authentication, you cannot give out specific account information on the common number, unless the taxpayer passes additional authentication. For additional information see IRM 21.1.3.2.4,Additional Taxpayer Authentication. If the owner of the TIN, fails the additional taxpayer authentication, you can provide general information on status updates and CIS case notes entered on "AMS" . In order to provide a reasonable time frame necessary to complete the processing of the case, general information from the case may be necessary.

    Caution:

    Do not assume that the taxpayer calling is the true owner of the SSN. Determine if you are speaking with the taxpayer who filed the TC 150 or the TC 976 and ask the appropriate questions related to the appropriate return and data on IDRS. Determining the true owner of the SSN can only be made by a CSR/TE who has been trained in working TIN-Related Problem cases and who makes the determination after all the necessary research steps are taken. As a CSR on the toll-free line, you may have the experience to work TIN-Related Problem cases, but your duties on the toll-free line do not allow the extended amount of time necessary to perform complete research.

  6. If required, customer service representatives (CSRs) should prepare a Form 4442 to refer taxpayer inquiries regarding open identity theft and Scrambled SSN cases, if this is their first time calling and the required processing time frame has passed. See IRM 21.9.2.2.1, Identity Theft Time Frame, to assist with the resolution of the case the following information should be obtained from the caller:

    • Include whether the caller is responding to a Letter 239C, Letter 4674C or Letter 4675C received and the date the letter was issued.

    • Include on Form 4442 telephone number(s) where the taxpayer can be reached and the best time for us to reach them.

    • Include the current address which may be, the address on the return, or address on Form 14039, if applicable.

    • Include information on whether the caller's return was filed electronically or by paper.

    • Include when the return was filed and the amount of refund expected.

    • Include any other pertinent information filed on the return that will be assist the IDT employee in resolving the case.

      Example:

      If the TIN was used by more than one family member, notate the name and correct TIN for each individual on Form 4442.

      Note:

      Also enter a case note on CIS as follows "IDT 4442 present - Check AMS History" .

    Do not prepare a referral (Form 4442) if this is the taxpayer's first time calling and the processing timeframe has not passed and the taxpayer is calling only to check on the status of their refund/claim and does not provide additional information to assist in resolving the case. Provide an update on the processing of the case based on your research and CIS case notes. As a reminder, you cannot provide specific details on the case, but you can utilize CIS cases notes to provide an expected time frame for resolution of the case. You should use a similar statement as stated below to minimize additional frustration from the taxpayer:

    "In order for the IRS to continue to combat identity theft, we must take careful steps to ensure we are processing cases accurately and efficiently. Identity theft case processing is complex and requires special handling. Because of the nature and complexity of these cases, processing time frames are taking longer than the normal processing time frame" .


    Exception:

    If the taxpayer has not yet filed a return, and tax-related identity theft is indicated, AM employees follow procedures in IRM 21.9.2.2, Identity Theft - Expanded Procedures, and IRM 21.9.2.3, Identity Theft - Telephone Overview and TAC employees follow procedures in IRM 21.3.4.32, Identity Theft Overview. Do not prepare a Form 4442 in these instances.

    Caution: If a referral is required while staffing the AM toll-free telephone line, or if you are located in a Taxpayer Assistance Center (TAC), prepare Form 4442, Inquiry Referral as follows:

    If there is... Then refer Form 4442 to...
    An open control The employee who has a control on the account.

    Note:

    Do not refer cases with IDRS numbers listed in IRM 21.5.2.3(5) (f), Adjustment Guidelines – Research This is a temporary holding number that is used as a result of the Site Specialization Process. For cases assigned to a temporary holding number, use the procedures below related to "no open control cases"

    Reminder:

    Open control cases should not be faxed to the ICM in Andover. The Form 4442 should be referred to the site where the open control resides.

    No open control (The case is not assigned to an employee or assigned to a temporary holding number.) To the Inventory Control Manager (ICM) in Andover. The fax number is ≡ ≡ ≡ ≡ ≡ ≡ (for internal use only). Address the Fax to "Andover ICM", and in the notes section of the fax cover sheet indicate, IDT1 or IDT3".

    Reminder:

    A referral should only be faxed to Andover CDS# if there is no open control to an employee and the taxpayer is providing additional information that will assist in the resolution of the case.

    Exception:

    Cases categorized as "MXEN" should not be faxed to Andover, unless your site does not work DUPF cases. These cases should be retained and worked at the local campus.

  7. Refer Scrambled SSN Forms 4442 as follows:

    If there is... Then refer Form 4442 to...
    An open control The employee who has a control on the account.

    Note:

    Do not refer cases with IDRS numbers listed in IRM 21.5.2.3(5)(f), Adjustment Guidelines – Research .This is a temporary holding number that is used as a result of the Site Specialization Process. For cases assigned to a temporary holding number, use the procedures below related to "no open control cases"

    Reminder:

    Open control cases should not be faxed to the ICM in Andover, unless your site does not work SCRM cases. The Form 4442 should be referred to the site where the open control resides.

    No open control (The case is not assigned to an employee) To the Inventory Control Manager (ICM) in Andover. The fax number is ≡ ≡ ≡ ≡ ≡ ≡ ≡ ≡ (for internal use only). Address the Fax to "Andover ICM", and in the notes section of the fax cover sheet indicate "SCRM".

    Note:

    A referral should only be faxed to Andover CDS# if there is no open control to an employee and the taxpayer is providing additional information that will assist in the resolution of the case.

  8. Low Income Taxpayer Clinics (LITCs) can assist low income taxpayers in resolving issues with the IRS involving a mixed entity or scrambled SSN case. LITCs also help educate taxpayers who speak English as a second language about their taxpayer rights and responsibilities. If appropriate, notify the taxpayer about the availability of LITCs. Refer the taxpayer to Publication 4134, Low Income Taxpayer Clinic List.

21.6.2.4.2.2  (10-01-2013)
Taxpayer Inquiries Involving Questionable Ownership of a Primary, Secondary or Dependent TIN on a Filed Return

  1. Examine taxpayer inquiries for any indication of identity theft involving mixed entity criteria.

    1. Examples involving two or more returns include, but are not limited to, references to a 673C letter, a notice of tax due, references to an attempt to e-file a return that was rejected due to a return already having been filed, a missing refund, or the amount of the refund is different than the amount claimed, etc. and the taxpayer claims she/he did not file more than one return. Examples in this category are considered tax-related identity theft issues.

    2. Examples involving only one posted return include, but are not limited to, references to impact to social security benefits, low income housing benefits, no filing requirement or below filing requirement, and the taxpayer claims she/he did not file a return. Examples in this category are considered tax-related identity theft issues.

    3. Examples involving TIN-Related Problem Secondary cases include issues in which a taxpayer's overpayment has been applied to an account that shows the taxpayer as the secondary filer and the taxpayer claims she/he did not file on that account. See IRM 21.6.2.4.2 Multiple Individuals Using the Same TIN. Examples in this category are considered tax-related identity theft issues.

  2. Follow procedures in IRM 21.6.2.4.2.3 Preliminary Research, for tax-related identity theft issues involving questionable ownership of a primary TIN on a filed return (mixed entity criteria).

    Note:

    For cases involving only one tax return also see IRM 21.6.2.4.2.8.1.2 #, Identity Theft - One Return Present.


  3. Provide guidance for non-tax-related identity theft using an appropriate letter such as Letter 239C. Examples would include references to a lost or stolen purse/wallet, questionable credit card activity, or a questionable credit report. If there are no indications the tax return involved tax-related identity theft, refer to resources provided in IRM 21.9.2.3, Identity Theft - Telephone Overview.

    Note:

    If you receive an identity theft inquiry that is non-tax related but has been categorized in error as a tax-related issue case, e.g., IDT1, or there is no evidence of tax related identity theft on the account, take the appropriate action to categorize the case as an "IDT4" control on ENMOD. If the erroneous category code "IDT1" control is already on ENMOD, change the category to "IDT4" . If the erroneous category code "IDT1" control is on a tax year, close the tax year control and open the "IDT4" control on ENMOD. In either case, take the appropriate action to assign the "IDT4" case to 0847124781 or if Spanish speaking, to 1030424443.

  4. All cases involving identity theft will receive priority treatment. This includes, but is not limited to, cases with identity theft documentation attached and cases referred via Form 14027B, Identity Theft Case Referral. Follow procedures in IRM 10.5.3.2.11.1.1, IPSU Monitoring Multiple Function Criteria (MFC) Accounts , when a Form 14027B, or a Form 14103 is received.

21.6.2.4.2.3  (10-01-2013)
Preliminary Research

  1. Make every effort to locate the correct TIN for each taxpayer before contacting the taxpayer(s).

  2. Utilize IMFOL, RTVUE, NAMES, INOLE, DUPOL, TRDBV and IRPTR, etc., to conduct complete research as applicable.

    Exception:

    CSR's are not required to conduct additional research to make a CN determination on cases referred by Field Assistance (FA). When a potential IDT victim visits a TAC office, FA will attempt to verify the identity of the victim and update AMS history with pertinent information that will assist the identity theft caseworker with resolution of the case. For cases where a TC 150 has already posted, and the taxpayer was unable to e-file because the primary or secondary SSN has already been used, FA will annotate an "S" in the upper right corner of Form 14039, or the police report in "red" on all cases that can be verified. These cases will also be controlled to IDRS # 1330075931 and you should see the activity code "FAIDTAM" . The account will be in status "B" and the category code should be "MISC" These cases will also be assigned a priority code 7. For additional information on FA procedures see IRM 21.3.4.31.3,Other Tax Related Identity Theft Issues.

    Exception:

    CSR's are not required to research cc IRPTR when working cases utilizing procedures in IRM 21.6.2.4.2.5.1, Electronic Fraud Detection System (EFDS) Case Processing, unless an exception applies. Please refer to IRM 21.6.2.4.2.5.1, if you are working an EFDS case.


    • In order to make the taxpayer whole, please ensure you address all related identity theft issues on the account, when applicable. Do not research previous tax years if those years are not listed on the taxpayer's correspondence and there is no indication that the IDT is affecting previous tax periods (such as a balance due or AUR assessment the taxpayer is unaware of).

    • Research subsequent years only if a return has posted since the taxpayer submitted his/her correspondence. For example, if you are working a Form 14039 filed for 2010, and a 2011 return posted after the Form 14039 was submitted, you may review the 2011 return and take action if the return was submitted by the non SSN owner or if prior year tax return(s) has posted on the account, and the taxpayer has indicated he/she was not required to file or has no filing requirement(s).

  3. If there is an open control or freeze condition present on IDRS, there may be some instances when the case should be routed. Please refer to the following IRM references to determine proper routing, if applicable:

    • AUR -IRM 21.3.1.4.58, Status of Underreporter Cases, (AUR will ensure all income is reported and reissue the CP 2000, if required).

    • Exam and Freeze Conditions - IRM 21.5.6.4.24, -L Freeze and IRM 21.5.3-1, Claim Processing with Examination Involvement. For closed Exam cases in status 90 or a TC 42X on the account, refer to IRM 21.5.10–2,AIMS STATUS CODE GUIDE CORRESPONDENCE EXAM, for appropriate routing to Exam.

    • SFR/NRF - IRM 21.5.3.4.10, Returns Prepared Under IRC Section 6020(b) or IRM 21.5.3.4.10.1, Non-Filer Reject Returns. (Do not route the case if a TC 599/89 has posted, or if the case meets NFR criteria).

    • ACS - Balance due IDT accounts in Status 22 should be routed to the appropriate function, per IRM 5.19.1.3.1Account Actions on Referral/Redirects and IRM 5.19.1-1 Collection Status Codes and Definitions.

    Caution:

    CSR's should not place a control in "B" when there are multiple years involved that are assigned to multiple employees. Refer to IRM 21.5.2.3(2), Adjustment Guidelines – Research, , to address multiple years.

  4. For ITIN cases, use EUP/RTS to locate DLNs to request any relevant original Form W-7 application documents.

    Note:

    For ITIN cases, if the Form W-7, Application for IRS Individual Taxpayer Identification Number, clearly indicates which taxpayer was assigned the ITIN, make a notation of this for the CSR/TE who will be working the case, after reassignment from Andover.

  5. As a reminder, DUPF employees are only required to order returns as indicated in IRM 21.6.7.4.4.1 (4), CP 36 - Control. If the return was not ordered, the CSR/TE's resolving the identity theft case will order the return. A return may be necessary, if any of the following conditions are met:

    • No information exists on cc TRDBV for the duplicate return

    • No income information is available on cc IRPTR

    • The case meets CAT A or DIF scoring criteria, per IRM 21.5.2.4.23.6, DIF SCORE or CLASSIFICATION "Send Return(s) to Examination for Review"

    • The case requires routing to AUR or Exam

    • The case is a true "MXEN" entity case

    • A CP 36I was generated, but the Form 14039 was not scanned to the case

    • The Form W-2 is missing and wages and withholding needs to be verified per IRM 21.6.3.4.2.2 (11) Withholding (W/H) Tax Credit

    • The return is missing schedules and/or required forms

    • The return is filed under an ITIN and reports wages

    • The taxpayer is deceased and you need Form 1310 or court documents to issue a refund

    • You suspect that the return is for another taxpayer with a valid SSN, but cannot locate the other SSN on NAMEI

    • You suspect that the return is for another tax year based on your research, but cannot validate this without the return

      Caution:

      When a refund is due, you should not order the return "only" to verify the signature. If the information has been transcribed on TRDBV, the signature should have been validated during processing. You should assume the return had a valid signature and continue processing. In addition, do not order the return if the entity information is not present on TRDBV, if it was not transcribed, this means the address and name was the same as MF. If you determine through additional research the signature is needed for other purposes and/or the entity information is incorrect, proceed and order the return.

      Note:

      This list is not all inclusive


    If the return is required and is not already attached to the case, CSR/TE's resolving the identity theft case should utilize cc ESTAB using "DV" as the definer. In the remarks section of the ESTAB request, annotate the following remarks, "AM-ID Theft" . This annotation will notify Files to send the request to the Image Control Team (ICT) team to scan, and also pull the returns as a priority.

  6. Search returns, schedules, and forms for a different TIN, if applicable. Research spouse and dependent information whenever available.

    Caution:

    If reprocessing a return and research indicates prior filing by the spouse, see IRM 21.6.7.4.5, Multiple Uses of Taxpayer Identification Numbers - CP 36F for additional information.

  7. Compare all documents and return information for:

    • Name

    • Social Security Number

    • Address

    • Occupation

    • Exemptions

    • Signatures (except for e-filed returns when a signature is unavailable)

    • Similar tax data

    • Form W-2, etc.

    • Marital status changes

    • Tax preparer

  8. Research the TIN (valid and invalid) to determine if there was a mixed entity, identity theft, or scrambled case in prior years and subsequent years to locate any possible cross-reference TIN.

  9. If a valid TIN can be located for each taxpayer and the CN is an SSN, change the category code to a MXEN and retain the case. See IRM IRM 21.6.2.4.2.421.6.2.4.2.4, Mixed Entity Procedures.

    Reminder:

    All cases assigned as a MXEN will be worked in the DUPF sites.

  10. CP36N and CP36P transcripts generate when a CP05A is present on the module. The CP36N generates when a CP05A is present and the module has a credit balance. The CP36P generates when a CP05A is present and the module has a zero or debit balance. If the case shows prior IVO involvement, before taking unnecessary preliminary research actions, see IRM 21.6.2.4.2.5.2 TIN-Related Problems Cases with Previous IVO Involvement.

  11. If the case shows a deceased taxpayer indicator on cc INOLET, before taking unnecessary preliminary research actions, see IRM 21.6.2.4.2.5.3 TIN Related Problem Cases with Deceased Taxpayer Indicators.

  12. Utilize any of the following tools to determine if the returns can be verified bad and/or good:

    • The Refund Scheme Listing

    • The IRP Data and

    • IRPTR/IDRS Data Decision Tree data, Exhibit 21.6.2-3

    If you determine the returns are bad and/or good, leave a CIS case note indicating "Bad/Good" or "Good/Bad " "per IRP data" or "Refund Scheme" . After this action has been completed, if the case has not been previously assigned to the Centralized Distribution Site (CDS) holding number, follow instructions per (16) below. If you are a CSR assigned to work identity theft cases, you should proceed to IRM 21.6.2.4.2.5.4, TIN-Related Problems for IRP Data and Refund Scheme Case Processing. DUPF employees have not been trained to work these type cases; therefore, the case should be assigned to the holding number.

  13. For non-streamline cases, record all significant research actions and information on the appropriate sheet according to the instructions in, IRM 21.6.2.4.2.6 ,TIN-Related Problem Research Sheet..
    Include a CIS case note when a determination is made (i.e., CP05A, DECD TP, Bad/Good per IRP data etc.). Refer to paragraph (17) below for additional information on how to categorize and reassign the case.

    Note:

    If you are preparing the case for reassignment to another CSR/TE or to the holding number, 0830141335, you may notate your research in the Notes section of the CIS case in lieu of using the research sheets.

  14. If a valid TIN cannot be located for each taxpayer and the CN is an SSN, or if the case does not meet the criteria in paragraphs (10), (11) or (12) above, refer to paragraphs (16) and (17) to determine how the case should be categorized (i.e, IDT1, or IDT3), before reassignment to the Andover holding number. International cases should be reassigned to "0530700000" . Refer to item number 15 in the CIS User Guide for additional information. Perform a complete statute search prior to reassigning the case and leave a case note that indicates the case is related to an identity theft issue.

    Caution:

    The ASED does not apply on a case that has been determined a nullity. The return must be considered valid in order for the ASED to apply. Refer to IRM 25.6.1.6.14 paragraph (3)(b), Criteria for Establishing a Statute of Limitations Period for additional information.

  15. If NUMIDENT information is needed the CSR/TE resolving the identity theft case will order the MFTRA "U" , if applicable. If the NUMIDENT shows multiple issuances of the social security card and the names are the same or similar, continue your research to determine if this is a scrambled SSN case.

    Caution:

    NUMIDENT is for internal use only; never send NUMIDENT to the taxpayer.

    Note:

    Only attach the NUMIDENT to the primary CIS case when a determination has been made that the NUMIDENT is required and necessary to resolve the case.

  16. Search returns and entity modules for indications of identity theft such as identity theft documentation attached to the return or a previously posted TC 971 with Action Code (AC) 501, or a TC 971 with Action Code 522. CP36I transcripts are also generated when ID Theft is indicated and/or with the filing of a Form 14039 that is attached to a duplicate return and Submission Processing codes a Special Processing Code (SPC) 8, which generates a TC 971 AC 522 on cc ENMOD.

    Note:

    Please see IRM 10.5.3.2.7, Overview - Identity Theft Supporting Documentation, for more information on identity theft documentation.

    Note:

    For all IDT cases with an IRS received date after January 7, 2013, acknowledging receipt of Form 14039 or similar statement is required per IRM 10.5.3.2.7(8), Overview - Identity Theft Supporting Documentation. The Letter 5073C, Acknowledgment Letter for Identity Theft Documentation, will be used to acknowledge receipt of Form 14039 or similar statement. There should be rare instances when an acknowledgement letter has not already been issued. Review cc ENMOD for other acknowledgment letters already issued (i.e., Letter 4402C issued). Per IRM 10.5.3.2.3.7(8),Overview - Identity Theft Supporting Documentation, if you are closing the case within 30 days of receipt, the closing contact will act as both an acknowledgement of receipt of the taxpayer's documents and the closing contact. Please exercise caution when acknowledging receipt of documentation by mail. The address on Form 14039 may be different from the address on ENMOD. Also refer to IRM 21.9.2.2.1, Identity Theft Time Frame. Procedures for incomplete documentation are also located in this same reference.

    Note:

    CSRs performing the resolving actions on a case should determine if documentation is needed to make a determination of TIN ownership. If enough information has been received, the CSR should work to resolve the case to completion. Requesting unnecessary documents will delay the processing of the case.

  17. After completing the applicable steps in paragraphs 1-16 above, the case should be categorized as "IDT1" , "IDT3" , or "IDT9" , as appropriate per IRM 21.6.2.4.2 Multiple Individuals Using the Same TIN. In some instances, the case may have already been assigned an IDT6 category code because an EFDS score was assigned to the case. As a reminder, this guidance is intended for CSRs/TEs that are required to reassign cases to the Andover holding number, because they have not been trained to resolve identity theft cases. If you are resolving an identity theft case, please refer to the "Order of Priority" chart below. Because some cases are categorized differently for reporting purposes, CSRs must ensure cases are worked in priority order. When a site is working a special project, CSRs should work cases as designated by their site.

    Note:

    Per IRM 21.8.1.1.1, Campus Consolidation and Program Centralization PSC will work any identity theft cases that has international involvement. Change the case data in CIS, to reflect the case is international when applicable.

    Order of Priority - IDT Case Processing
    1st Priority Operation Assistance Requests (OARs)
    2nd Priority IDT9
    3rd Priority Priority Code 7 Cases
    (This includes FA cases)
    4th Priority Priority Code 8 Cases
    5th Priority IDT1 - Aged Cases
    (Can also become an IDT8, at the point of closure)
    6th Priority IDT3 - Aged Cases
    (Can also become an IDT8, at the point of closure)
    7th Priority IDT6
    (Worked as priority if the site has IDT6 cases in inventory)



    TIN-Related Problem Case Types
    Category Code Defining Characteristic
    MXEN Involves an inadvertent or processing error
    IDT1 Involves taxpayer identified identity theft
    IDS1 Involves Spanish taxpayer identified identity theft
    IDT3 Involves IRS identified identity theft
    IDS3 Involves Spanish IRS identified identity theft
    IDT6 Involves Electronic Fraud Detection System (EFDS) cases
    IDT8 Involves identity theft (CP05A, cases with prior IVO involvement or Deceased Taxpayer cases ONLY)
    IDT9 Involves an Identity Theft Assistance Request (ITAR)
    IDS9 Involves a Spanish Identity Theft Assistance Request (ITAR)

    For "IDT1" , "IDT3" , "IDT6" "IDT8" and "IDT9" cases perform the following actions:

    • Ensure all relevant documents have been scanned to the case.

    • Ensure all actions taken are noted/attached to the case per paragraph (13) above

    • Ensure all related CIS cases (for the same tax year) are linked to the IDT case before closing your control.

    • Ensure the 5073C acknowledgement letter was issued per paragraph (16) above (The acknowledgement letter is not required for IRS identified IDT cases).

    • Ensure that a TC 971, AC 522 reflecting an appropriate Tax Administration Source Code is input on cc ENMOD. See IRM 10.5.3.2.7.3 Marking Taxpayer Accounts When Accepting Identity Theft Supporting Documents for additional information. For taxpayer identified IDT, where the taxpayer has initially asserted identity theft , the account should already be marked with a TC 971 AC 522 "PNDCLM" . A second TC 971 AC 522 reflecting receipt of documentation is also required using the appropriate Tax Administration Source Code. For IRS identified IDT, a second TC 971 AC 522 is not required if supporting documentation was not requested and received. For cases already marked by another business unit for the same year and same tax administration code, do not input a second TC 971 AC 522.

      Exception:

      Input of TC 971 AC 522 is not necessary for cases that have been categorized as a "MXEN"

    • Update the Doc Type and Statute Clearance check box when reassigning a case to CIS user.

    • Reassign the case to IDRS number 0830141335 when appropriate. See the CIS Performance Guide – CSR Guide for the correct procedures on these required actions. Also see IRM 21.5.1.5.2(10),Cases Currently Assigned in CIS for additional information.

      Exception:

      Cases categorized as "MXEN" , "IDT6" or "IDT8" should NOT be assigned to the Andover holding number.

    Note:

    The specialized sites will receive IDT1's created by Andover and Fresno IPSU teams. IPSU does not perform the preliminary research prior to assignment to specialized sites. For more information, please see IRM 21.9.2.4.1, Self Identified - Non-Tax-Related Identity Theft - (Andover and Fresno IPSU only) .

    The mere mention of "identity theft" or of an identity theft event on any document processed in Accounts Management does not automatically establish the document as an IDT1 case. This holds true even if the taxpayer indicates the identity theft event has tax implications. The issue must be identified and worked, if possible, by the area initially receiving the case. For example, a Form 1040X with a note attached that the taxpayer had his wallet stolen will be worked per normal procedures by the site receiving the Form 1040X. The notification of the identity theft event, i.e., the theft of the wallet, will be addressed by following the guidelines in IRM 21.9.2.4.1, Self Identified - Non-Tax-Related Identity Theft (Andover and Fresno IPSU only).

    A case reassigned to 0830141335 in error will be returned to the originating site, unless your site has the skill to resolve the case. This will result in an adverse impact to the taxpayer due to the delay in processing.

21.6.2.4.2.3.1  (10-01-2013)
Required Action on All Identified IDT Cases

  1. Some "IDT1" cases are primarily notifications from the taxpayer that another individual has filed a federal tax return using his or her TIN. These notifications may be received in the form of a police report or the Form 14039, Identity Theft Affidavit, and may or may not include federal or state issued identification. A common occurrence is multiple controls on a tax year involving a duplicate filing , or mixed entity control, and the "IDT1" or "IDT3 " control. If you determine that the notification "IDT1" or "IDT3" control is related to an open "DUPF" or mixed entity control on the module, link the "IDT1" case to the open mixed entity case, then close the "DUPF" case.

  2. The receipt of a "notification" or an "incidental" Form 14039 or some similar type of information, e.g., a police report regarding identity theft, requires you to change the category of the "DUPF" or MXEN case to "IDT1" , if the taxpayer attached the documentation required with Form 14039, or "IDT3" if the taxpayer did not attach the required documentation.

    If you have such a case that does not have all the documentation generally required with the Form 14039, you do not have to request such documentation. The CSR/TE performing the resolving actions on the case will determine if such documentation is needed to make a determination of TIN ownership.

  3. If the Form 14039, Identity Theft Affidavit or correspondence is received alleging preparer misconduct rather than ID theft, prepare and send a Letter 131C, Information Insufficient or Incomplete for Processing Inquiry, advising the taxpayer that we are returning their Form 14039 or correspondence. Include the following verbiage in the letter Internal Revenue Service. "We’re returning your Form 14039 because the information you provided indicates you have a return preparer misconduct issue. Complete the enclosed Form 14157 and Form 14157-A. If you visited a return preparer, but didn’t authorize the filing of a return, then check Box 11(a) "Other" of Form 14157 and write in "Return Filed Without Authorization or Consent" . Be sure to include the documentation listed on page two of Form 14157-A, to verify your claim. No action can be taken until you send the required forms and documentation. Send the forms and documentation to the following address" :

    Internal Revenue Service
    AM Preparer Complaints
    5333 Getwell Road
    Mail Stop 58
    Memphis, TN 38118

  4. Some incidental or notification "IDT1" , "IDT3" or "TPRQ" cases that do not involve a mixed entity issue may be received by the designated specialized units working TIN-Related Problem cases. These receipts generally fall into 2 categories:

    • The case involves an incidental Form 14039 that is attached to correspondence requiring the resolution of a non-TIN-Related Problem issue.

    • The case involves a self identified-non-tax-related identity theft issue with incomplete documentation.




    If either of these types of cases is received in a specialized unit working TIN-Related Problem cases, the case should not be reassigned back to the originating area. It should be worked by the specialized unit or assigned as deemed appropriate by your local management.

    See IRM 21.9.2.4.1,Form 14039 or Taxpayer Correspondence with Incidental Form 14039, for general guidelines on processing either of the two categories of Form 14039 cases described above.

  5. Prior to January 7, 2013, "IDT1" , "IDT3" or "TPRQ" cases described in this subsection did not receive an acknowledgment letter. For all cases received after January 7, 2013, acknowledging receipt of Form 14039 or similar statement is required, per IRM 10.5.3.2.7(8) , Overview - Identity Theft Supporting Documentation. The Letter 5073C, Acknowledgment Letter for Identity Theft Documentation, will be used to acknowledge the Form 14039 or similar statement . IRM 21.3.3.1.1, Policy Statement P-21-3 (formerly P-6-12). IRM directs us to issue timely and quality responses to taxpayer correspondence. "IDT1" , "IDT3" or "TPRQ" cases described in this subsection are, according to Policy Statement P-6-12, considered correspondence. Generally, the response provided to the taxpayer who has submitted this type of correspondence is the closing Letter 239C, Letter 4674C, or CP01 notice informing the taxpayer that we have made an SSN ownership determination. A response, as described here, is considered timely if issued within 180 days of the received date of the "notification" "IDT1" , "IDT3" or "TPRQ" document.

    Note:

    The table in IRM 21.9.2.2.1, Identity Theft Time Frame, shows that the date an inquiry was received by a CSR on the Toll-Free line could also be the starting date for the 180 day time period. It would be the starting date if the inquiry precedes the receipt of the Form 14039. See IRM 21.9.2.2.1Identity Theft Time Frame, for a table showing timeliness guidelines.

    Note:

    See the "Exception" in paragraph (1) of IRM 21.3.3.4.2.2, Interim Responses, for more information on the 180 day response time and Form 14039.


    If a closing response cannot be issued by the 180th day in this situation, an interim letter must be sent informing the taxpayer that it will require additional time to issue a response providing the results of our processing of the case. The time-frame given in this interim letter may not exceed 60 days.

    Note:

    The issuance of a closing letter may or may not coincide with the complete resolution of the case. The closing letter is sent when we can share with the taxpayer the results of our processing of the case, e.g., we have made an ownership determination. We should not wait until all resolving actions, e.g., TC 400 account transfer procedures, have been completed before sending a closing letter.



    If additional interim letters are needed, the time-frame given in the letter must not exceed 60 days. Every effort, however, must be made to provide a closing response within the initial 180 day time-frame.

    Caution:

    A reasonable effort must be made to respond or send an interim letter within the time-frame previously given. Such an effort is considered reasonable if it does not hinder the primary objective of resolving the mixed entity condition and issuing a quality closing response.

    Caution:

    Be sure you are sending any necessary letters to the correct address. The Correspondex letter system will default to the Address of Record which may or may not be the correct address for your correspondence. Override the Address of Record when appropriate.

21.6.2.4.2.3.2  (10-01-2013)
Reversing TC 971 AC 501 or TC 971 AC 522

  1. There may be instances when it is necessary to reverse a TC 972 AC 501 or a TC 972 AC 522. Use TC 972 in CC FRM77 on the Entity module to reverse a TC 971 AC 501 or TC 971 AC 522. In the TRANS-DT field, enter the transaction of the AC 501 or AC 522 being reversed. In the SECONDARY-DT field, enter the tax year of the AC 501 or AC 522 being reversed in MMDDYYYY format. In the MISC field, enter "WI AMADJ XXXX" where "XXXX" represents a valid reason code. For additional information on reversing the AC 501 and/or AC 522, see the IRM references below:

    • IRM 10.5.3.2.10.2,Manually Reversing TC 971 AC 501 and IRM 10.5.3–5, TC 972 AC 501 - Reversal of TC 971 AC 501.

    • IRM 10.5.3.2.8, Reversing Pending Identity Theft Claims - TC 972 AC 522 NORPLY or NOIDT and IRM 10.5.3–13,TC 972 AC 522 — Reversal of TC 971 AC 522.

21.6.2.4.2.4  (10-01-2013)
Mixed Entity Procedures

  1. A mixed entity case is created when two taxpayers file a return with the same TIN, also known as the common number (CN). Normally, this condition is identified while working CP 36, Duplicate/Amended Filing Conditions, transcripts.

21.6.2.4.2.4.1  (10-01-2013)
Resolving Mixed Entity Cases

  1. Analyze the case and identify the correct and incorrect taxpayer for the CN as follows:

    1. Taxpayer A correctly used the TIN and remains on the CN.

    2. Taxpayer B incorrectly used the TIN and is input to a valid TIN, or to an Internal Revenue Service Number (IRSN), located through research/taxpayer contact.

      Note:

      There can be more than one Taxpayer "B" that incorrectly used the TIN. See IRM 21.6.2.4.2.8.3, A Different Valid TIN Is Not Located AND Neither Return was Filed by Common Number Owner (Bad/Bad), for additional guidance on how to process this type case.

      Caution:

      Taxpayer B is moved to an IRSN only when it has been verified that the CN does not belong to Taxpayer B and a valid different number cannot be located.

      Example:

      Taxpayer A, John Smith, and Taxpayer B, Jane Smythe, are both using the CN. NUMIDENT indicates that the CN was assigned to John Smith. NUMIDENT does not indicate that the CN was ever assigned to Jane Smythe. Research and correspondence with Taxpayer B does not provide a valid TIN for Taxpayer B, Jane Smythe. Taxpayer A, John Smith, is the correct CN owner and would remain on the CN. Taxpayer B, Jane Smythe, is the incorrect taxpayer and would be moved to an IRSN.


      Caution:

      If Taxpayer B's return is to be reprocessed AND Taxpayer B's return shows a primary and a secondary taxpayer, research the secondary taxpayer's account to determine if a return has already been filed by the secondary taxpayer for the tax year at issue. If a return has been filed by the secondary taxpayer, resolve the duplicate filing issue before reprocessing Taxpayer B's return. Not resolving the duplicate filing issue will result in the generation of a CP 36F case. See IRM 21.6.7.4.5,Multiple Uses of Taxpayer Identification Numbers - CP 36F

  2. If either account contains an offset (TC 896 or TC 898) to a state or federal agency, take no action before referring to IRM 21.4.6.4.2.11, TOP Offsets Involving ID Theft .

  3. Consider possible changes to the Return Processable Date. See IRM 21.5.6.4.17, I- Freeze.

  4. For mixed entity cases involving identity theft, see IRM 21.6.2.4.2.8.1.1 #, Identity Theft - More Than One Return Present.

  5. Route cases with a Z freeze, to the Scheme Development Center (SDC). For cases with a P- Freeze with category code PFRZ, refer to IRM 21.5.6.4.31, P- Freeze for additional guidance, take no action unless the Z freeze is released. If the Z freeze is released, follow established mixed entity procedures.

    Caution:

    Do not follow SDC instructions which deviate from established procedures. Established procedures do not permit SDC determinations of the CN owner.

  6. Refer to the SDC any "leads" related to alleged stolen identity accounts, data that may lead to a fraudulent filing of tax returns for the purpose of gaining false or inflated refunds, or potential ERO schemes, etc. Do not refer the case. Continue to work the case. Use Form 4442 to provide the following information:

    1. SSN(s) and tax year(s) involved

    2. Brief description (e.g., alleged stolen identity). Notate that the Form 4442 is a "Lead Only."

    3. Copy of the source of allegation (e.g., copy of taxpayer correspondence), if available

    4. Copy or CIS print of the paper return (if a subsequent paper return was filed and taxpayer(s) are alleging stolen identity)

21.6.2.4.2.4.2  (10-01-2013)
Valid TIN Located - Taxpayer "A" Posted First

  1. The following procedures must be used when a valid different TIN is found for Taxpayer B and Taxpayer A posted first:

    1. Input TC 290 blocking series 00 and use Taxpayer A's return as the source document. Notate in remarks "Mixed entity." or similar remarks.

      Note:

      If Taxpayer A's return is not present, input TC 290, blocking series 05, and "NSD" to release the "A" freeze.

    2. Input TC 971 with action code 002. Enter Taxpayer B's TIN as a cross-reference.

    3. Input TC 971 with action code 017 on Taxpayer B's account after the TC 000 posts. Enter Taxpayer A's TIN as a cross-reference.

      Note:

      Close the CIS base and monitor the TC 000 for posting then input the TC 971 AC 017.

    4. Update the entity on Taxpayer A's account if the original information has changed.

    5. Transfer Taxpayer B's payments to his/her account and establish a current entity if not present.

      Note:

      If TC 000 is the first action input, the credit transfer bypasses the National Account Profile (NAP) validity check.

    6. Take the appropriate steps to post Taxpayer B's tax information to the correct TIN. See (2) below.

      Note:

      If a refund was issued from the CN to Taxpayer B, the refund transaction must be moved to Taxpayer B's TIN. See IRM 21.5.2.4.23.10, Moving Refunds.

    7. If the taxpayer or the preparer used an incorrect TIN, send a Letter 257C advising the taxpayer of the correct TIN to use. If Submission Processing (SP) processed the return using a different TIN, send a Letter 257C but do not mention the TIN SP edited on the return during processing.

    8. Send a closing Letter 4674C to Taxpayer A if the conditions in paragraph "i" below are applicable. On cases filed as married filing jointly, the Letter 4674C should be addressed to both taxpayers.

      Exception:

      If a balance due or other account issue is involved, or if the language in the Letter 4674C is not appropriate for your specific case scenario, send a Letter 239C to the taxpayer for cases input with a TC 971 AC 501. A CP 01 will systemically generate between 2 and 12 cycles after the input of the TC 971 AC 501.

    9. If the incorrect TIN is NOT the result of taxpayer error, preparer error, or SP error, input the appropriate TC 971 AC 501 or TC 971 AC 506 with the appropriate post and delay code(s) on the entity module of the CN. Use the SECONDARY-DT field to indicate the tax year in question. Use the TRANS-DT field to indicate the current (input) date. Input "WI AM MULTFL" in the MISC field, if applicable. For information on allowable field entries see IRM 10.5.3-3, Acronyms and Definitions .

21.6.2.4.2.4.3  (10-01-2013)
Valid TIN Located - Taxpayer "B" Posted First

  1. The following procedures must be used when a valid different TIN is found for Taxpayer B and Taxpayer B posted first:

    1. Adjust the CN account to reflect Taxpayer A's return data using blocking series 00. Use priority code 1, if the return requires DIF scoring. Adjust the Assessment Statute Expiration Date (ASED), if necessary. Notate in remarks "MIXED ENTITY - DUP BECOMES ORIGINAL." or similar remarks.

      Note:

      If working on CIS, the adjustment is still input using blocking series 00, since TP A's return is considered the original return, however it should be input as a NSD.

      Note:

      If ID theft year is 2008 and FTHBC was received from the TC 150, see IRM 21.6.4.4.19.4, Manually Adjusting the Recapture Amount.

      Note:

      Address any incorrect Combat Zone changes made to TP B's account, if TP A was in a Combat Zone.

      Caution:

      Combat Zone (CZ) accounts, identified by a -C freeze, indicate a taxpayer who is or was serving in a designated combat zone area. NOTE: The -C freeze stays on the account even after the taxpayer is no longer in the CZ. When working an account that contains a –C freeze, additional research is required to determine the taxpayer's CZ status. Research CC IMFOLE for the Combat indicator on Line 11, to determine the correct action to take based on the following.
      If Combat indicator is "1", then the taxpayer is still serving in a combat zone. Any compliance activity such as assessing or collecting tax is prohibited. However, if the taxpayer has other issues or requests information, you may work these other issues and contact the taxpayer if needed.
      If Combat indicator is "2", then the taxpayer is no longer a combat zone participant. Follow normal procedures to work the case.

      Caution:

      If Taxpayer B requested a direct deposit and the refund did not generate due to the TC 976, then TC 971 AC 001 must be input before adjusting the CN to agree with Taxpayer A's return. TC 971 must post before the adjustment. Use a cycle delay of 2 cycles on the adjustment when inputting the TC 971 and the adjustment at the same time. The TC 971 AC 001 will prevent the refund from being direct deposited into Taxpayer B's account.

      Note:

      If a refund was issued on the CN to Taxpayer B, it must be moved to Taxpayer B's valid TIN. See IRM 21.5.2.4.23.10,Moving Refunds, for moving refund procedures.

      Caution:

      If reprocessing a return and moving a previously issued refund, enter Computer Condition Code (CCC) O in the filing status portion of the return to prevent a second refund.

    2. Use a hold code to prevent issuing erroneous notices to the taxpayer.

    3. Notify the taxpayer if a balance due results.

    4. Correct the entity module to reflect Taxpayer's A address using information on CIS, AMS and IDRS to determine the most current address..

    5. Transfer Taxpayer B's payments to his/her correct account.

    6. Take the appropriate steps to post Taxpayer B's tax information to the correct TIN. See (2) below.

    7. Input TC 971 with action code 001. Enter Taxpayer B's TIN as cross-reference.

    8. Input TC 971 with action code 017 on Taxpayer B's account after the TC 000 posts. Enter Taxpayer A's TIN as a cross-reference.

      Note:

      Close the CIS base and monitor the TC 000 for posting then input the TC 971 AC 017.

    9. If the taxpayer or the preparer used an incorrect TIN, send a Letter 257C advising the taxpayer of the correct TIN to use. If SP processed the return using a different TIN, then send a Letter 257C but do not mention the TIN SP edited on the return during processing.

    10. Send a closing Letter 4674C to Taxpayer A if the conditions in paragraph "k" below are applicable. On cases filed as married filing jointly, the Letter 4674C should be addressed to both taxpayers.

      Exception:

      If a balance due or other account issue is involved, or if the language in the Letter 4674C is not appropriate for your specific case scenario, send a Letter 239C to the taxpayer for cases input with a TC 971 AC 501. A CP 01 will systemically generate between 2 and 12 cycles after the input of the TC 971 AC 501.

    11. If the incorrect TIN is NOT the result of taxpayer error, preparer error, or SP error, input the appropriate TC 971 501 or TC 971 AC 506 with the appropriate post and delay code(s) on the entity module of the CN. Use the SECONDARY-DT field to indicate the tax year in question. Use the TRANS-DT field to indicate the current (input) date. Input "WI AM MULTFL" in the MISC field, if applicable. For information on allowable field entries see IRM 10.5.3-3, Acronyms and Definitions

    12. If Taxpayer A indicates "yes" to the Presidential Election Campaign Fund (PECF) and Taxpayer B did not, then prepare a dummy Form 1040X. Refer to procedures in IRM 21.6.7.4.12,Presidential Election Campaign Fund (PECF).

  2. The following should be taken into consideration when processing Taxpayer B's tax information to the correct TIN:

    If Then
    The TC 976/977 return bypassed Discriminate Information Function (DIF) scoring After adjusting the account to reflect the TC 977/976 return information forward the return to Examination for DIF scoring if it meets any of the criteria in IRM 21.5.2.4.23.6 , DIF SCORE or CLASSIFICATION "Send Return(s) to Examination for Review". DO NOT refer Forms 1040EZ.
    There is no TC 150 on Taxpayer B's account for the tax period involved Reprocess Taxpayer B's return. See IRM 21.5.2.4.23,Reprocessing Returns/Documents .
    There is a TC 150 on Taxpayer B's account for the tax period involved Adjust the account, if necessary. Follow IRM 21.6.7.4.4,Duplicate or Amended Returns - CP 36 (Duplicate Filing Condition).

  3. If Taxpayer A is due a refund, issue a manual refund if a refund cannot be systemically released, before the return has been DIF Scored. Refer to IRM 21.4.4.2, Why Would A Manual Refund Be Needed, and IRM 21.4.4.4, Preparation of Manual Refund Form, for additional guidance on issuing a manual refund and to determine if the refund should be issued systemically.

    Exception:

    If Taxpayer A (or the spouse of Taxpayer A) filed a Form 8379, Injured Spouse Allocation, do not attempt to issue a refund. Instead follow the instructions in (4) below.

  4. If Taxpayer A (or the spouse of Taxpayer A) filed an injured spouse claim, correct the account to reflect Taxpayer A’s information and then refer the Debtor Master File Case (DMFC) to the specialty group to process the injured spouse claim:

    1. Follow all instructions in (1) and (2) above except use hold code 4 on the adjustment and/or use TC 570 on credit transfers to hold the overpayment.

    2. After inputting all account actions, close the CIS case.

    3. Open a new CIS case with category code "DMFC" . Assign the case to IDRS number "0534027692" For the required fields, input the doc type as "Injured Spouse Claim" , use program and function code "ADJ-710-97140" , "Priority 2" and reason "Form 8379 attached" ..

    4. Link the new CIS case to the closed CIS case.

21.6.2.4.2.4.4  (10-01-2013)
Valid Different TIN Not Located for Taxpayer "B"

  1. If the case does not involve an ITIN and a different valid TIN is not located for Taxpayer B through research/correspondence, obtain an Internal Revenue Service Number (IRSN) for Taxpayer B and take the following action:

    If Then
    Taxpayer A posted first
    1. Follow procedures in IRM 21.6.2.4.2.4.2 Valid TIN Located - Taxpayer "A" Posted First. Enter the IRSN where entry of a TIN for Taxpayer B is applicable.

      Exception:

      Do not send the Letter 257C. Send a 4675C letter advising Taxpayer B to contact SSA and use the IRSN for federal tax purposes until SSA determines the correct SSN. SSA will advise the taxpayer to file Form W-7 to obtain an ITIN if the taxpayer cannot obtain a SSN.

      Caution:

Streamline Identity Theft Case Processing (CAT 7)

  1. All cases identified as streamline will be worked utilizing the CAT 7 process in this section, unless an exception applies in the applicable If/Then chart. A streamline case is a case that needs less research to determine the CN owner, and/or less processing is needed to resolve the case because a return can be considered a nullity. A nullity does not have to be reprocessed and any lost refund can be moved to the 1545 account. The following IRM references below are used to process streamline CAT 7 cases:

    • IRM 21.6.2.4.2.5.1, Electronic Fraud Detection System (EFDS) Case

    • IRM 21.6.2.4.2.5.2, TIN Related Problem Cases with Previous IVO Involvement

  4. If the only case control is an "IDTX" and the case had not been resolved , then the CSR/TE will open a new control base and assign the case to him/herself. Note: CSR/TE should "not" reassign the "IDTX" base to him/herself.

  5. If multiple case controls (i.e. an IDTX and IDT1 and/or 3) are present on the account and the CSR/TE has determined no action other than initial research (i.e., ordering of documents, numidents, TRPRT, etc). has been taken on the "IDTX" category case, then the CSR/TE will reassign the IDT1 and/or IDT3 case control to him/herself.

    Reminder:

    In both of the above reassignments, the CSR/TE should follow IRM 21.9.2.4.2, Tax-Related Identity Theft - (Andover and Fresno IPSU only) to notify IPSU that the case has been resolved using EFDS procedures by denoting "EFDS" on the Form 14027-B

    (2) CSR/TE determines EFDS closing actions (i.e., monitoring, referral/freeze held by another business function, awaiting taxpayer response, prior adjustment actions, etc.) have been taken by another employee
    Annotate Prev/Action Taken/EFDS in CIS Case notes.

    Note:

    If there is an open control base, CSR/TE should close their control base with an IDT6 and use OFP 710-40016. (Do not close the open control base held by another employee).

    :
    (3) TIN contains more than one TC 976/TC 977 on the account Refer to IRM 21.6.2.4.2.3, Preliminary Research, to determine if another streamline process or non-streamline process applies. Close the case using the appropriate category code and program code (e.g. IDT1, or IDT3 and OFP 710–40011).
    Exception: If the multiple TC 976/977s are "true dup" cases, continue to process using EFDS procedures.
    CSR/TE should close the second TC 976/977 DUPF control as a true DUPF when finished with the IDT case and report case as an IDT6 and use OFP 710-40016.
    (3) SE income on the SSN owner's return has either a "Lost" or "No Lost " refund Process the non owner's return utilizing the nullity procedures, but continue processing the SSN owner's return utilizing the appropriate procedures in IRM 21.6.2.

21.6.2.4.2.5.2  (10-01-2013)
TIN Related Problem Cases with Previous IVO Involvement

  1. Integrity & Verification Operation (IVO) is a pre-refund revenue protection program focused on identifying and stopping fraudulent refunds primarily generated from wage and withholding type of income. Accounts Management utilizes the CAT 7 process to streamline working identity theft cases. Much of this activity occurs very early in the tax year prior to normal processing time frames and involves only originally filed returns such as TC 150/TC 976/TC 977.

  2. Accounts with IVO involvement will show TC 971(s) with AC 134/617 and the account will reflect issuance of a 4464C letter and/or CP 05 notice. CP36N and CP36P transcripts also generate when a CP05A is present on the module. The CP36N generates when a CP05A is present and the module has a credit balance. The CP36P generates when a CP05A is present and the module has a zero or debit balance. Refer to IRM 21.5.6.4.35.3, -R Freeze Modules With Integrity & Verification Operation (IVO) Involvement (4464C Letter or 4115C Letter), for other indicators of IVO activity. Cases where IVO determined the return to be fraudulent will show one of the following:

    • The account will be completely reversed.

    • The account will be completely reversed with the exception of a refundable credit.

    • The account won’t be reversed but TXMOD shows that a CP 05A notice was issued (IDT8 case).

    • The account won’t be reversed but TXMOD shows a MISC field "AMWEX60033 NOCP05A" (IDT8 case)

    All cases meeting the criteria in the last two bullet items above, must be worked by CSR/TE's trained in the DUPF sites.

  3. An IVO open control can be identified on IDRS by the organizational range 06500–06539. No contact is required for an open control with the following category codes: NCAT, ECAT, NRAM and ERAM. Close your CIS case and control to the IVO control and notate your case in AMS.

    Note:

    Before closing your control to IVO, link all related active and archived cases

  4. Do not attempt to contact IVO units or route cases to the following controls. Continue to follow established IRM procedures for your case type (examples: DUPF, XRET, IDT1, TPRQ, etc.).

    Open Control Explanation
    0650199999 Generic number for closed CI prior year Transcripts. Tax Payer Relations has forwarded the transcript to the generic number

TIN Related Problem Cases with Deceased Taxpayer Indicators

  1. Cases with deceased indicators can be identified on cc INOLET or IMFOLE with the actual date of death (DOD) displayed on IDRS. Fraudulent activity on a deceased taxpayers’ account usually occurs very early in the tax year, prior to normal processing time frames, and involves only originally filed returns such as TC 150 TC 976 or TC 977.

  2. Decedent cases usually require the filing of a Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer. You should check for evidence that is required when processing a deceased taxpayer’s return. See IRM 21.6.6.3.22.2, Processing Decedent Account Refunds, for additional information.

  3. The absence of the Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer or missing personal representative information for an estate, may be an indication that the first return is potentially fraudulent. Conduct thorough research before you make a determination that the return is fraudulent.

21.6.2.4.2.5.4  (10-01-2013)
TIN-Related Problems for IRP Data and Refund Scheme Case Processing

  1. Cases that can be determined bad/good or good/bad utilizing the Refund Scheme Listing or, IRP data, and the IRPTR/IDRS Decision Tree will be processed using the applicable Category 7 process in the If/Then chart below. Careful and complete research must be conducted, before proceeding with case processing on these type cases. If a case is received that appears to be fraudulent and does not have an existing treatment stream, see IRM 21.5.3–7, Fraud Referral Claims.

  2. Cases that cannot be verified utilizing the above criteria will be worked following procedures in IRM 21.6.2, Adjusting TIN-Related Problems. Under no circumstances should the Category 7 (nullity) procedures be used when additional information is needed to validate the return , unless one of the following apply:

    • The Refund Scheme Listing contains a Schedule C income scheme

    • Schedule C income was reported on a return determined "bad" and the refund has been lost. A return can be determined "bad" , once you have completed all of the necessary research (i.e., Research of IRP Data, the IRP Data Decision Tree and IDRS) to support your determination.



    Each return must be considered separately. Once a determination is made for each return, you may need to issue an IRSN to one or both taxpayers, you may be able to nullify one or both returns, and you may either back out the account or adjust the account to show return information under the common number. If a CSR determines both returns are "bad/bad " utilizing the above criteria per (1) above, or if the case contains Schedule C income with a lost refund, the lead or manager must review the case and concur with the determination, before the return(s) can be treated as a nullity to ensure the return is not nullified in error. Accurate and complete research must be performed, in order to avoid a potential missed assessment. If a manager/lead concurs with the findings and the return(s) are bad/bad or Sch C (lost refund) , a CIS case note should be placed on CIS indicating "Manager or Lead concurs with bad/bad or Sch C (lost refund) determination"

  3. Before determining a return "bad " , you must review the following:

    • The Refund Scheme Listing. (If a return matches the criteria for one of the schemes on the Refund Scheme Listing, the return can be nullified. No additional validation is required), or

    • The IRP data and IRPTR/IDRS Decision Tree. Review the return and data on CIS, RTVUE, TRDBV, IRPTR etc. Verify three inconsistencies between the "bad" return and the previous filing history to make a final determination that the return is a nullity. (You cannot assume because a Form W-2 was not filed that the return is fraudulent). There may be some instances where the employer failed to file the required Form W-2.

      Caution:

      If the unemployment compensation is unverifiable, you can treat the return as a nullity. If unverifiable Sch C income is reported on a return deemed "bad" and there is "no lost refund" , you cannot nullify the return. You will need to process the return to an IRSN.

  4. Before determining a return "good" , you must review the following:

    • CIS, RTVUE, TRDBV, IRPTR, etc., to validate the information claimed on the return. ( You can utilize the IRP data to verify wages/withholding, unemployment compensation, pension income, social security income, interest and dividend income and verifiable Schedule C income reported on cc IRPTR)

    • The IRP data and IRPTR/IDRS Decision Tree. (verify three items listed on the IRPTR/IDRS Decision Tree to make the final determination of TIN ownership. If you do not have 3 years of IRP data, but your research supports a CN ownership determination, you will need lead/manager approval before proceeding. This is another level of validation to ensure returns are not nullified in error.

    • If the case received from the CN owner appears to be fraudulent, see IRM 21.5.3–7,Fraud Referral Claims.

    Note:

    If you determine both returns bad, but only one of the returns is deemed bad per the criteria for the refund scheme process or IRP data process, you can nullify the return that meets that criteria and move the other one to an IRSN, per IRM 21.6.2.4.2.8.3 A Different Valid TIN Is Not Located AND Neither Return was Filed by Common Number Owner (Bad/Bad).

    • Disregard any instructions regarding EFDS and STARS, these systems are used by IVO only.

    • Use "WI ID THEFT ERRONEOUS REFUND" or similar remarks on Form 3809.

    • Use the proper tax administration codes when using the TC 971 AC 501 or TC 971 AC 506. "WI AMADJ" should be used for taxpayer identified IDT, or "WI AM" should be used for IRS identified IDT. See IRM 10.5.3-3, Acronyms and Definition for additional information. The tax administration code should be placed on the identity theft victims account.

    • Disregard instructions to send the 4310C letter (This letter is used by IVO only).

    • For cases closed with a TC 971 AC 501, a CP01 notice will systemically generate within 2-12 cycles after input of the TC 971 AC 501. If a balance due or other account issue is involved, send a Letter 239C to the taxpayer for cases input with a TC 971 AC 501.

    • For cases closed with a TC 971 AC 506, If the case is closed with an AC 506, send the appropriate 4674C closing letter. If the language in the Letter 4674C is not appropriate for your specific case scenario, use the Letter 239C. On cases filed as married filing jointly, the Letter 4674C should be addressed to both taxpayers.

    • For cases related to a decedent, See IRM 21.6.6.3.22.1, Updating the Entity on Decedent Accounts .

    • Use the appropriate identity theft indicator TC 971 AC 501 or TC 971 AC 506 with the appropriate "tax administration source" (i.e., INCOME, MULTFL, NOFR, OTHER, INCMUL) for your business unit. See the Exhibit in IRM 10.5.3, Identity Protection Program, for more information on these codes. The identity theft indicator should be placed only on the victim's account. See IRM 10.5.3.2.5 (3), Identity Theft Tracking Indicator, under the note for additional guidance.

    • Do not input a TC 971 AC 501 or TC 971 AC 506 on an IRSN. If you are re-sequencing an account, then the SSN needs to be re-established and the codes re-input to the SSN. If either of these action codes are placed on an account assigned an IRSN in error, the account should be reversed with a TC 972 using IRSERR as part of the MISC field.

    • For FMS offset reversals, refer to IRM 21.4.6.4.2.11,Top Offsets Involving ID Theft.

    • For erroneous refunds issued to the SSN owner, refer to IRM 21.4.5.5, Account Actions for Category D Erroneous Refunds

    • Ensure the address on the CN is updated on cc ENMOD. Review AMS, CIS and Form 4442 to ensure the address is updated to most recent address.

    • Ensure all related CIS cases (for the same tax year) are linked to the IDT case, before closing your control.

    • To ensure a TDI notice is not issued to the secondary TP whose spouse (the primary) was a victim of IDT, input TC 594 AC 084 to satisfy the secondary TIN’s filing requirement, if one is not present. Make sure there is a name line for the secondary TP's TIN on the Masterfile for the same year or earlier. If not, update ENMOD with a name line for the secondary TP's TIN for the same year.

    • For a "lost refund" , utilize the information in IRM 25.25.4.8, Identity Theft CAT 7 Bad Return Posted/Good Return Posted- Lost Refund - Process. Guidelines on completing Form 3809 to debit the 1545 General Ledger Account can be found in the second column. Attach a PDF file of the Form 3809 to your CIS case. For Form 3809 reversals, see IRM 21.6.2.4.2.5.6 Form 3245/3809 Reversals.

    • If the TC 976/977 return bypassed Discriminate Information Function (DIF) scoring, then forward to Examination for DIF scoring also input a priority code 1 on the case. Use local procedures. The return should only be sent if it meets any of the criteria in IRM 21.5.2.4.23.6, DIF SCORE or CLASSIFICATION "Send Return(s) to Examination for Review". DO NOT refer Forms 1040EZ

    • If Taxpayer A is due a refund, issue a manual refund if a refund cannot be systemically released. When it is necessary to issue a manual refund, HC 4 must be used. Disregard any instructions to use HC 4 in a situation other than when issuing a manual refund or when appropriate. The manual refund should be issued before the return has been DIF Scored. Input a priority code 1 on the case. Refer to IRM 21.4.4.2, Why Would A Manual Refund Be Needed and IRM 21.4.4.4, Preparation of Manual Refund Form for additional guidance on issuing a manual refund.

    • If the posting of an 840/841 requires monitoring, .you should open a monitor control with the category code "MISC" after you have closed your TIN-Related Problem (IDT) case. refer to IRM 21.5.2.4.19, Verifying Complete Adjustments for general information.

    • If Taxpayer A has a balance due, and the return was filed and/or balance due paid late, see IRM 20.1.2, Failure To File/Failure To Pay Penalties, IRM 20.1.3.1.2, Manual Penalty Adjustments and IRM 20.1.3.1.2.2, Return Posted to Wrong TIN or Period, for additional information. Also refer to IDT Hub, which is located on the AM IDT Resource Page for canned paragraphs that can be used to correspond with the taxpayer.

    • Ensure the applicable actions in IRM 21.6.2.4.2.3 Preliminary Research, have been addressed.

21.6.2.4.2.5.6  (10-01-2013)
Form 3245/3809 Reversals

  1. In certain circumstances, it may be necessary to reverse previous actions taken that debited the 1545 account with the posting of a TC 841 or TC 700 to the tax account. For example, duplicate TC 841s, actual credit has been returned to the module etc.

  2. When it is determined by the originator or employee resolving a case that a TC 841 was initiated in error, a Form 3245, Posting Voucher - Refund Cancellation or Repayment, and Form 3809 Miscellaneous Adjustment Voucher must be completed. The Form 3245 should be sent to Accounting to reverse the TC 841 with a TC 843 and the Form 3809 will be used to credit the 1545 account. Forms 3245/3809 must include a brief explanation of the error and the DLN of the TC being reversed must be annotated on the forms. See Exhibit 21.6.2-4, Form 3245 Reversal and Exhibit 21.6.2-5, Form 3809 Reversal, for proper annotations required for Form 3245/3809. In addition to this, 3 copies of Form 3809 and Form 3245 should be submitted when requesting a reversal and the originator should open a control base indicating "843 or 702 request" to prevent duplicate submissions to Accounting. Make sure the TC 841 to be reversed has actually posted to the taxpayer account before initiating the reversal action. Forms 3245/3809 should be forwarded to the Accounting function for numbering and journaling. See IRM 3.17.243.4.9,Duplicate ID Theft TC841/700 posting Identified by Non-Accounting Operations, for additional guidance.

    Note:

    Forms 3245/3809 must be complete and legible for processing or the forms will be rejected back to the originating location. A current TXMOD print must be attached, or the Form 3245/3809 will be rejected back to the originating location.

  3. When it is determined by the originator or employee resolving a case that a TC 700 was a duplicate or in error, a Form 3809, Miscellaneous Adjustment Voucher should be sent to Accounting to reverse the TC 700 that posted to taxpayer account with a TC 702 and credit to the 1545 account. Form 3809 must include a brief explanation of the error and the DLN of the TC being reversed. See Exhibit 21.6.2-5, Form 3809 Reversal, for proper annotations required on Form 3809. Make sure the TC 700 to be reversed has actually posted to the taxpayer account before initiating the reversal action. Form 3809 should be forwarded to the Accounting function for numbering and journaling. See IRM 3.17.243.4.9,Duplicate ID Theft TC841/700 posting Identified by Non-Accounting Operations, for additional guidance. As a reminder, the Accounting Function is responsible for all guidance related to Form 3245 and Form 3809. AM does not have any authority over this process.

    Note:

    Form 3809 must be complete and legible for processing or it will be rejected back to the originating location. A current TXMOD print must be attached or the Form 3809 will be rejected back to the originating location.

  4. If you identify multiple TC 700's that have posted to the account, input a TC 570 on the account to avoid erroneous refund(s).

    Note:

    When multiple TC 700's result in a refund, complete research is needed to determine the recipient. If it's an ID theft account, follow ID theft procedures. If the owner of the EIN/SSN benefited from the refund then follow erroneous refund procedures in IRM 21.4.5.5, Account Actions for Category D Erroneous Refunds .

  5. Please use the chart below for proper routing.

Preparing a Duplicate Form 3245 and Form 3809

  1. If it has been at least 4 weeks since submission of Form 3245 and Form 3809, and there is no evidence of the pending credit on the module, then resubmit the form and annotate the form(s) with "Potential Duplicate" at the top. Also indicate potential duplicate on the fax sheet(s) and the date(s) the forms were originally submitted.

21.6.2.4.2.6  (10-01-2013)
TIN-Related Problem Research Sheet

  1. The TIN-Related Problem Research Sheet is not required when working cases utilizing the streamline CAT 7 process in IRM 21.6.2.4.2.5.1 Electronic Fraud Detection System (EFDS) Case, IRM 21.6.2.4.2.5.2 TIN-Related Problem Cases with Previous IVO Involvement, IRM 21.6.2.4.2.5.3 TIN-Related Problem Cases with Deceased Taxpayer Indicators, or IRM 21.6.2.4.2.5.4. For all non-streamline case processing, the TIN-Related Problem Research Sheet is required. This research sheet is found on SERP under the "IRM Supplements" tab. The research sheet can also be completed using the aMend tool formerly known as the Mixed Scrambled Entities (MSE) Tool. Per IRM 21.2.2-2, ACCOUNTS MANAGEMENT MANDATED IAT TOOLS, the use of the aMend tool is mandatory when working identity theft cases. The information retained/recorded must be sufficient to support the actions taken on the case.

    Reminder:

    The TIN-Related Problem Research Sheet should not be confused with the Case History Sheet that is required for cases referred to SSA.

21.6.2.4.2.7  (10-01-2013)
Case History Sheet

  1. If through your research you have already determined a case has to be referred to SSA (i.e., numident records confirm that two individuals have been assigned the same TIN by SSA), the case history sheet should be completed. Additional information on scrambled cases can be located in IRM 21.6.2.4.3.2 Beginning Scrambled Procedures. A case history sheet is required for a case that is to be sent to SSA for resolution. The history sheet must include all information and actions taken to resolve the case. Include the following:

    • Common number (CN)

    • IRS or CP notice received date

    • Tax periods involved

    • Each taxpayer's name, address and IRSN (if applicable)

    • Research requests (e.g., IMFOL, MFTRA), include dates

    • DLN of returns requested, include date requested and date received

    • Other TINs and actions, include dates other actions are taken

    • All taxpayer contact

  2. Form 13708, Form 13708A, Form 13708B, and/or Form 13708C, Mixed Entity/Scrambled SSN Case History Sheet, are required when working a case to be sent to SSA for resolution. All account actions, taxpayer contact and SSA contact must be included on the history sheet. Retain a copy of the completed Case History Sheet with the case. Scan/attach for CIS inclusion only the pages of the Sheet that notate actions taken. The information retained must be sufficient to support the actions taken on the case.

  3. Research information for all cases not sent to SSA for resolution must be recorded on the TIN-Related Problem Research Sheet..

21.6.2.4.2.8  (10-01-2013)
Non-Streamline IDT Case Processing - Determining Ownership of the Common Number

  1. Every effort will be made to determine ownership prior to contacting the taxpayer. The Letter 239C requesting information from the taxpayer will not be sent if neither return was filed by the Common Number (CN) owner. See (2) and (3) below for researching possible identity theft.

  2. Research both returns. Compare them with any "good" prior year returns. Look for situations that may indicate identity theft, such as a return with wages and withholding for a taxpayer who had only retirement or disability income in prior years. Identity theft returns filed in an attempt to generate a fraudulent refund may also show the following characteristics:

    • Refundable credits claimed, no Form W-2 income, included

    • Adoption credit

    • First Time Homebuyer Credit

    • Refundable Education Credit (Form 8863)

    • Only Education Credits of $1,000 claimed on return

  3. See IRM 25.25.2.13, Operation Mass Mailing Criteria (OMM) for the characteristics of the most common identity theft scheme, Operation Mass Mailing (OMM).

  4. If NUMIDENT or, for ITIN cases, the Form W-7, Application for IRS Individual Taxpayer Identification Number, clearly shows the owner of the SSN or ITIN, follow mixed entity procedures in IRM 21.6.2.4.2.4,Mixed Entity Procedures.

  5. If the case is a True Scrambled SSN, apply the following procedures only for research purposes. Keep in mind that all True Scrambled SSN cases will go through the scramble process and will be sent to SSA for resolution. Do not make a determination of ownership for a True Scrambled SSN case.

21.6.2.4.2.8.3  (10-01-2012)
A Different Valid TIN Is Not Located AND Neither Return Was Filed by Common Number Owner (Bad/Bad)

  1. The procedures below must be used when all of the following are met:

    • Two Taxpayer Bs (i.e., the TC 150 and the TC 976 are both bad) and

    • A valid TIN cannot be located for either taxpayer and

    • The case does not meet the criteria to be nullified per the listing in IRM 21.6.2.4.2.5 Streamline Identity Theft Case Processing (CAT 7).

    Note:

    If you determine both returns bad, but only one of the returns is deemed bad per the streamline process, you can nullify the return that meets the nullity criteria and move the other one to an IRSN per instructions below.

    1. Zero out the account, Input TC 29X, blocking series 05, and "NSD" to release the "A" freeze.

    2. Use a hold code to prevent issuing erroneous notices to the taxpayer. For additional information on hold codes, see IRM 21.5.2.4.15, Rules on Hold Codes (HC).

    3. Correct the entity module to the last known good address for the common number owner. If you are unable to find a last known good address, correct the address to the address of the service center.

    4. Input TC 971 with action code 001. Enter the IRSN that is associated with the 150 as the cross-reference

    5. Input TC 971 with action code 002. Enter the IRSN that is associated with the 976(s) as a cross-reference.

    6. If a refund was issued on the CN to Taxpayer B that posted as the 150, it must be moved to the 150 taxpayer’s IRSN. See IRM 21.5.2.4.23.10, Moving Refunds, for moving refund procedures.

    7. Input TC 971 with action code 017 on both IRSN accounts after the TC 000 post. Enter the CN TIN as a cross-reference.

      Note:

      Close the CIS base, monitor the TC 000 posting and then input the TC 971 AC 017.

    8. Take the appropriate steps to post both taxpayers’ tax information to the correct TINs. Reprocess Taxpayer B's return. See IRM 21.5.2.4.23, Reprocessing Returns.

    9. Transfer payments to the correct account if necessary.

    10. Input TC 971 AC 506 with a posting delay of 2 cycles on the entity module of the CN. Use the SECONDARY-DT field to indicate the tax year in question. Use the TRANS-DT field to indicate the current (input) date. Input "WI AM MULTFL" in the MISC field. For information on allowable field entries see IRM 10.5.3-10.

    11. Add a case note on CIS and/or the TIN-Related Worksheet "CSR determined both returns bad"

      Note:

      For the purpose of this subsection, do not correspond to Taxpayer B. If you are able to update the account to the last known address for the CN owner, send the appropriate letter.

    Reminder:

    If all case actions have been completed and you are monitoring the account to ensure proper posting, close the case and establish a monitor base on IDRS using category code "MISC" with the current date as a received date.

    Note:

    If statute or statute imminent return, refer to IRM 21.6.2.4.2.9,Determining When Specific Year Account Information Must Be Moved

21.6.2.4.2.9  (10-01-2013)
Determining When Specific Year Account Information Must Be Moved

  1. Use the guidelines in the following subsections when determining whether posted tax account information for a particular year must be moved.

    Note:

    These guidelines are applicable only if you are having to consider whether you should move posted tax data, e.g., tax, credits, refunds. On the other hand, if, as an example, the only"incorrect" transaction posted is a TC 976 belonging to another taxpayer, you may be required to follow the requirement to "move" the TC 976. Moving the TC 976 would involve inputting a TC 971 AC 002 and taking any necessary action to ensure the posting of the TC 976 tax information on the appropriate TIN.

21.6.2.4.2.9.1  (10-01-2013)
Collection Statute Expiration Date Expired or Imminent

  1. If all other statute expiration dates have expired and there is no indication of activity or pending activity on the tax year account, do not move posted tax account information if the Collection Statute Expiration Date (CSED) is expired or has less than 10 months remaining before it expires. No action is required on these tax years. This guideline is applicable for all TIN-Related problem case categories, i.e., MXEN, IDT1, IDS1, IDT3, IDS3, IDT6, IDT8, IDT9, IDS9, SCRM, SSA2, and NMRG.

    Exception:

    Stolen Identity Cases are exempted from normal Statute processing. To that end, Identity Theft cases do not truly have a CSED. Any cases received with the statement "Exception IDT1 - Identity Theft Account" or "Exception IDT3 -Identity Theft Account" etc., written in the remarks field of the Form 12810 are to be processed.

21.6.2.4.2.9.2  (10-01-2013)
Tax Year Account Move Conditions-Applicable for MXEN, IDT1, IDS1, IDT3, IDS3, IDT6, IDT8, IDT9, IDS9, SCRM, and SSA2 Cases

  1. If moving posted tax account information is an issue, the tax account information should be moved when any of the following conditions are met:

    • The Assessment Statute Expiration Date (ASED) is open.

      Reminder:

      If the ASED is expired or imminent on a tax return to be reprocessed, NEVER abate tax on the "from" account until the reprocessing is complete and the tax has posted. Suspend the case to Statute if a return needs to be reprocessed and the ASED has expired or is imminent, per IRM 21.5.2.4.23.4 Statute Imminent Documents..

      Caution:

      The ASED does not apply on a case that has been determined a nullity. The return must be considered valid in order for the ASED to apply. Refer to IRM 25.6.1.6.14 paragraph (3)(b), Criteria for Establishing a Statute of Limitations Period for additional information.

    • The correct taxpayer has also filed a return for the same tax year and the tax return amounts have been combined/adjusted. In this case it is necessary to keep the correct taxpayer’s information on the account and move off the incorrect taxpayer’s information.

      Note:

      This bullet is referring to tax years in which the correct taxpayer's and the incorrect taxpayer's tax account information items have been "mixed." . "Mixed" here means that the income amounts were combined and the tax and any credits were adjusted if necessary.

    • There is a "-C" freeze on the account. A "–C" freeze indicates the taxpayer is/was in a combat zone and the time period for filing a return for that tax year may have been extended.

      Caution:

      Combat Zone (CZ) accounts, identified by a -C freeze, indicate a taxpayer who is or was serving in a designated combat zone area. NOTE: The -C freeze stays on the account even after the taxpayer is no longer in the CZ. When working an account that contains a –C freeze, additional research is required to determine the taxpayer's CZ status. Research CC IMFOLE for the Combat indicator on Line 11, to determine the correct action to take based on the following:
      If Combat indicator is "1", then the taxpayer is still serving in a combat zone. Any compliance activity such as assessing or collecting tax is prohibited. However, if the taxpayer has other issues or requests information, you may work these other issues and contact the taxpayer if needed.
      If Combat indicator is "2", then the taxpayer is no longer a combat zone participant. Follow normal procedures to work the case.

    • There is a balance owed on the tax year account.

    • The tax year account has an overpayment that must be refunded.

    Caution:

    If there is an indication another area is considering action on the tax year account, e.g., an open control by Exam, AUR, Collections, etc., contact that area. The tax year may need to be moved based on the action they are taking on the account. Document your contact in the CIS notes.


    If Then
    None of the conditions in the bullet-list above are met Proceed to IRM 21.6.2.4.2.10, Not Moving Specific Year Account Information.
    One or more of the conditions in the bullet-list above is/are met Proceed to IRM 21.6.2.4.2.11, Moving Specific Year Account Information.

21.6.2.4.2.9.3  (10-01-2013)
Tax Year Account Move Conditions--Applicable for NMRG Cases

  1. If moving posted tax account information is an issue, the tax account information should be moved when any of the following conditions are met:

    • The Assessment Statute Expiration Date (ASED) is open.

      Reminder:

      If the ASED is expired or imminent on a tax return to be reprocessed, NEVER abate tax on the "from" account until the reprocessing is complete and the tax has posted.

      Caution:

      The ASED does not apply on a case that has been determined a nullity. The return must be considered valid in order for the ASED to apply. Refer to IRM 25.6.1.6.14 paragraph (3)(b), Criteria for Establishing a Statute of Limitations Period for additional information.

    • There is a "–C" freeze on the tax year account. A "–C" freeze indicates the taxpayer is/was in a combat zone and the time period for filing a return for that tax year may have been extended
      .

      Caution:

      Combat Zone (CZ) accounts, identified by a -C freeze, indicate a taxpayer who is or was serving in a designated combat zone area. NOTE: The -C freeze stays on the account even after the taxpayer is no longer in the CZ. When working an account that contains a –C freeze, additional research is required to determine the taxpayer's CZ status. Research CC IMFOLE for the Combat indicator on Line 11, to determine the correct action to take based on the following:
      If Combat indicator is "1", then the taxpayer is still serving in a combat zone. Any compliance activity such as assessing or collecting tax is prohibited. However, if the taxpayer has other issues or requests information, you may work these other issues and contact the taxpayer if needed.
      If Combat indicator is "2", then the taxpayer is no longer a combat zone participant. Follow normal IRM procedures to work the case.

    • There is a balance owed on the tax year account.

      Note:

      Contact Automated Underreporter (AUR) if there is an AUR assessment which appears to be incorrect. See 4.13.7–6 Addresses for AUR Reconsideration Requestsin IRM 4.13.7, They may give you approval to reverse the AUR assessment. Document your AUR contact and their response on the CIS case.

    • The tax year account has an overpayment that must be refunded.

    Caution:

    If there is an indication another area is considering action on the tax year account, e.g., an open control by Exam, AUR, Collections, etc., contact that area. The tax year may need to be moved based on the action they are taking on the account. Document your contact in the CIS notes.


    If Then
    None of the conditions in the bullet-list above are met Proceed to IRM 21.6.2.4.2.10, Not Moving Specific Year Account Information.
    One or more of the conditions in the bullet-list above is/are met Proceed to IRM 21.6.2.4.2.11, Moving Specific Year Account Information.

21.6.2.4.2.10  (10-01-2013)
Not Moving Specific Year Account Information

  1. Take the following actions when you have determined, per the subsections above, that it is not necessary to move posted tax account information. Unless specifically noted, the actions listed in this paragraph apply to MXEN, IDT1, IDS1, IDT3, IDS3, IDT8, IDT9, IDS9, SCRM, SSA2, and NMRG cases. The bullet items listed here are related to the actions required on the "IRSN" .

    • Refer the case to your Lead or designated individual for approval not to move the tax account information. If approved, the Lead or designated individual must notate approval in the CIS Case Notes.

    • Establish a name line on the "to" account for the tax year not being moved. Include the name(s), filing status, and spouses's SSN (if applicable) as shown on the return.

    • Input a TC 971 AC 001 with the return received date on the "from" account to cross-reference to the "to" account. For NMRG cases the "from" account is the tax year on the other side of the No Merge, usually the IRSN.

    • After the name line has posted on the "to" account, input a TC 971 AC 017 on the "to" account to cross-reference to the "from" account. Use the received date of the return not being moved.

    • For MXEN, IDT1,IDS1, IDT3, IDS 3, IDT9, IDS9, SCRM, and SSA2 cases, enter the following CIS case note, filling in the applicable year: "Tax Year YYYY not filed by TP. See TC 971 AC 001 X-Ref" .

      Note:

      If reactivation requires obtaining microfilm, a note on CIS is sufficient indicating the location of the cross-reference tax year.


    Caution:

    The ASED does not apply on a case that has been determined a nullity. The return must be considered valid in order for the ASED to apply. Refer to IRM 25.6.1.6.14 paragraph (3)(b), Criteria for Establishing a Statute of Limitations Period, for additional information. If the return is determined to be valid, an IRSN should be obtained in order to process the return for Taxpayer B.

  2. Take the following additional actions for the tax year(s) that will remain posted on the account. These additional actions listed in this paragraph apply ONLY to MXEN, IDT1, IDS1, IDT3, IDS3, IDT9, IDS9, SCRM, SSA2 cases. The bullet items listed here are related to the actions required on the "SSN" .

    • For the "from" tax year(s) account(s), the tax year(s) account(s) not being moved, change the name line on the tax year(s) to: "NOT FILED] NAMC" . "NAMC" here represents the name control of the taxpayer who owns the SSN. You will type in the name control of the SSN owner instead of typing in "NAMC" . Also update the address to the most current address, if applicable.

    • If the return that posted to the Common Number, on the "from" account tax year has Self-Employment (SE) income, input TC 898/TC 895 and/or TC 891/TC 898 to zero out primary SE and Medicare income. Input TC 879/TC 896 and/or TC 892/TC 899 to zero out the secondary SE and Medicare income. DO NOT adjust the tax or item reference number TC 889 (SE tax amount) on the account.

    • If an overpayment on the tax year account not being moved is over one-year old, move such overpayment to excess collections.

      Note:

      If the taxpayer has a valid TIN and a refund should be issued, the tax year account must be moved to the taxpayer's valid TIN.

    • Any overpayment that has been offset to a Bureau of Fiscal debt must be reversed, using hold code 4. If the overpayment is over one year old, move it to excess collections. A letter must also be sent to the taxpayer who has the FMS debt, notifying them of the reversal. If the FMS offset is over 6 years old, refer to IRM 21.4.6.4.2.11, TOP Offsets Involving ID Theft.

    • Reverse any IRS offsets. If the overpayment is over one-year old, move the overpayment to excess collections. A letter should be sent to the SSN owner informing them of the overpayment reversal.

    • If adjusting 2008 and FTHBC was claimed by the bad taxpayer, see IRM 21.6.4.4.19.4, Manually Adjusting the Recapture Amount, to update the IMFOLF information.

21.6.2.4.2.11  (10-01-2013)
Moving Specific Year Account Information

  1. If there are 180 or more days remaining before the ASED expires, reprocess the return.

  2. If there are less than 180 days remaining before the ASED expires, refer the return to Statute for a prompt assessment.

    Caution:

    The ASED does not apply on a case that has been determined a nullity. The return must be considered valid in order for the ASED to apply. Refer to IRM 25.6.1.6.14 paragraph (3)(b), Criteria for Establishing a Statute of Limitations Period for additional information.

    If the tax year account is within 180 days of the ASED, DO NOT abate tax on the "from" account prior to the tax being posted on the "to" account. Once the return has been reprocessed and the tax information has posted, or a prompt assessment has been made on the "to" account, the "from" account may be backed off to the correct amount.

    Reminder:

    If the ASED is expired, NEVER abate tax on an account and attempt to reprocess the return.

  3. If moving posted tax account information is an issue, the ASED is expired for the tax year(s) at issue, and any of the conditions are met, as applicable, in IRM 21.6.2.4.2.9.2, Tax Year Account Move Conditions--Applicable for MXEN, IDT1, IDS1, IDT3, IDS3, IDT6, IDT9, IDS9, SCRM, and SSA2 Cases, or IRM 21.6.2.4.2.9.3, Tax Year Account Move Conditions--Applicable for NMRG Cases, take action to move the tax account information as appropriate. If applicable, initiate a manual account transfer using Form 12810, Account Transfer Request Checklist.

    Note:

    For general information when the tax year account must be transferred via Form 12810 per the guidelines above, see IRM 25.6.1.9.9.3, Correct Records on Expired Statute Periods.

    Reminder:

    When the tax year account must be transferred via Form 12810, the tax year account must be in debit or zero balance. Accounting will reject any requests where the tax year account is showing or will show, once the Form 12810 transfer has been completed, a credit balance. Credit balances must be resolved expeditiously, whether as a refund to the correct taxpayer, if allowable, or as a transfer to Excess Collections. Make sure the entity information for the IRSN account has posted and all freeze conditions are resolved prior to sending the Form 12810 to Accounting.


    Reminder:

    If all other statute expiration dates have expired and there is no indication of activity or pending activity on the tax year account, do not move an incorrectly posted tax year if the Collection Statute Expiration Date (CSED) is expired or has less than 10 months remaining before it expires. No additional account moving action is required on these tax years.

Sending the Letter 239C and Telephone Contact-Stage One

  1. Correspond with the taxpayers, using the Letter 239C Exhibit 21.6.2-1, Paragraphs for Letter 239C. Include the questionnaire. Retain copies of the Letter 239Cletters in the case file. See IRM 21.6.2.4.3.5 Determining if Refund Should be Released, for additional information that must be requested in the Letter 239C. The suspense period for the Letter 239C is 40 days, 70 days for overseas taxpayers.

    Caution:

    Do not advise the taxpayer to contact SSA for a "Social Security Administration Social Security Number Verification" printout.

    Note:

    It is not necessary to send the questionnaire Letter 239C again if it has already been sent due to previous IRM procedures. Also, if the letter has been sent AND a CN ownership determination has already been made, it is not necessary to proceed with the guidelines in this subsection.

21.6.2.4.2.12.2  (10-01-2012)
Telephone Contact Guidelines

  1. Allow 21 days from the input date of the Letter 239C for the taxpayer to receive the letter before IRS-initiated telephone contact is attempted. The guidelines in this subsection also apply to taxpayer-initiated telephone contact.

    Note:

    The 21-day time-frame assumes the Letter 239C is issued by the Correspondex system. You may adjust the time-frame based on the procedures in your work area. The overall rule is to allow the taxpayer sufficient time to receive the letter

  2. Telephone contact is primarily for the purpose of obtaining information. Because the case involves undetermined ownership of the SSN, do not provide any information to the taxpayer unless specifically authorized to do so per the guidelines below.

    Note:

    IRM 21.1.3.4, Other Third Party Inquiries, authorizes you to accept information from any third party even if the provider of the information does not have a written or oral authorization from the taxpayer.

  3. Even though you are primarily obtaining information, ask disclosure verification questions based on the Letter 239C and on the information on this particular taxpayer's return. Do not ask any questions that might inadvertently disclose information merely by asking the question.

    1. Identify yourself, provide your ID number, inform the taxpayer you are calling on behalf of the Internal Revenue Service, and provide a purpose statement for the disclosure verification questions you are about to ask. See the suggested purpose statement below:

      "While we are reviewing your account, we would like to ask a few questions to determine whether or not any discrepancies are present on the account."

      Note:

      See IRM 21.3.11.11.5, Making Outgoing Calls for further guidelines on placing IRS-initiated telephone calls to taxpayers.

      Note:

      On the TIN-Related Problem Research Sheet, record that telephone contact was made, the number called, and the name of the individual to whom you are speaking. Also record the answers you receive from the taxpayer Also add a CIS note indicating "Telephone Contact Made"

    2. If you are initiating the call prior to receiving the taxpayer's response to the Letter 239C, ask the taxpayer if he or she recently received a letter from the IRS. If the taxpayer indicates he or she has not received a letter from the IRS, ask the taxpayer to call us if he or she does receive a letter. Apologize for any inconvenience and politely terminate the call.

      Caution:

      If the taxpayer provides an address that is different from our records, do not change our records and do not issue a Letter 239C to the address. Because the ownership of the SSN is in question, we will not be making any entity changes to the account. We will not be sending any information to the taxpayer, e.g., the Letter 239C, because we do not yet know if this taxpayer is involved in any way with the case. Under no circumstances would you indicate you are calling because two individuals are filing tax returns using the same SSN. The only basis for discussing this issue would be the taxpayer acknowledging the issue on the basis of the Letter 239C we sent.

      Note:

      The prohibition in the "Caution" above on sending the Letter 239C does not restrict the Taxpayer Advocate Service (TAS) from initiating any contacts required by TAS guidelines

    3. If you are initiating the call and the taxpayer indicates he or she has received our letter, ask the taxpayer to have in hand a copy of the letter and a copy of the tax return. If the taxpayer cannot readily obtain the letter, ask the taxpayer to call us as soon as possible after locating the letter. (Note the "Caution" in (b) above.) If the taxpayer has at least the letter in hand, ask the taxpayer for the following:
      His or her TIN
      The ten digit number in the upper right hand corner of the letter
      The tax period(s) indicated on the letter
      The address shown on his or her return (latest year if the case involves multiple years)
      Filing status on the return
      Whether a refund was claimed and the amount
      The information in the first paragraph of the letter (Under "Why We're Sending You This Letter" )

    4. If the taxpayer's answers indicate at least that he or she has the letter in hand, proceed to paragraph (4). Also proceed to paragraph (4) if the taxpayer indicates he or she does not have the letter in hand but he or she provides correct information regarding the tax return. If the taxpayer does not meet either of these conditions, apologize for the inconvenience and politely terminate the call. See the "Caution" in (b) above

    5. If the taxpayer is initiating the call, follow (c) above.

  4. Preface the asking of the questions below with the following statements to the taxpayer:

    Note:

    Modify your statements and questions appropriately to the taxpayer if you are working a True Scrambled SSN case. If you are working a True Scrambled SSN case, tell the taxpayer that it appears the Social Security Administration has assigned the SSN to more than one individual. Strongly recommend that the taxpayer contact SSA as soon as possible. Any information the taxpayer provides by answering these questions will assist SSA.


    "Our records indicate that the Social Security Number you used on your tax return for the tax year(s) of 'YYYY' (state the tax year(s) in question) was also used by another individual on his or her federal tax return. Disclosure laws prevent us from providing any information regarding the other individual. We would like to ask you a few questions in order to determine which individual should be using the Social Security Number for the filing of federal tax returns.
    "The IRS does not issue Social Security Numbers, and the IRS does not determine who the true owner of the Social Security Number is for the purposes of Social Security benefits. The Social Security Administration is a separate government agency and is the final authority on determining the ownership of the Social Security Number. We recommend strongly that you contact your local Social Security Administration office to ensure that your Social Security records are correct. The questions we would like to ask you today, consequently, pertain only to the filing of your federal income tax return. "
    "The questions are based on information received from the Social Security Administration. The answers you provide will assist us in resolving this issue as quickly as possible. An incorrect answer or a response of "I don't know" will not necessarily result in the Social Security Number not being assigned to you for federal income tax purposes."
    "Are you willing to answer the questions?"
    "

    • If the taxpayer indicates he or she is not willing to answer the questions, simply thank the taxpayer for his or her time and inform the taxpayer that our determination will be made based on the information at hand. Inform the taxpayer that he or she will receive a letter regarding our determination within 6 to 8 weeks.

    • If the taxpayer asks for the questions to be sent to him or her by mail, inform the taxpayer that the questions not already listed on the letter he or she received must be given and answered during direct telephone conversation. If necessary, you may inform the taxpayer that this method is intended to ensure that the person using the Social Security number in error does not have the opportunity to research and find the correct answers.

    • If the taxpayer is willing to answer the questions, proceed with asking the questions in the questionnaire portion of the Letter 239C and the question in IRM 21.6.2.4.2.12.2.1, Supplementary Questions. Have a copy of the Numident print available, related to the SSN, when asking the Supplementary Questions.

      Caution:

      Do not respond in any way that might be construed as a confirmation or a rejection of the validity of the taxpayer's response. The purpose of asking the questions is to obtain information for consideration, not to provide information to the taxpayer. Indications of confirmation or rejection would constitute providing information to the taxpayer.

    • On the TIN-Related Problem Research Sheet record the answers you receive.

    • We can make a determination without the questionnaire and documents in our file, but if an ownership determination is not made, the taxpayer will not receive his or her refund unless he or she has met all the conditions of IRM 21.6.2.4.3.5, Determining if the Refund Should be Released.

    • A True Scrambled SSN Case requires the actual documents, completed by the taxpayer, for the file going to SSA. If you believe the number is a True Scrambled, tell the taxpayer to send the documents requested in the Letter 239C and the questionnaire as soon as possible.

    • After all the questions have been asked and the answers recorded, state the following to the taxpayer:
      "Thank you for the information you have provided. When we have completed our gathering and reviewing of information, we will notify you by mail of our determination. The expected time-frame for the process of review and notification is generally 6 to 8 weeks. If possible, we will issue our determination more quickly than the expected time-frame."
      "Please keep in mind the information we provided earlier in the conversation: The IRS does not issue Social Security Numbers, and the IRS does not determine who the true owner of the Social Security Number is for the purposes of Social Security benefits. The Social Security Administration is a separate government agency and is the final authority on determining the ownership of the Social Security Number. We recommend strongly that you contact your local Social Security Administration office to ensure that your Social Security records are correct. The questions we have asked today, consequently, pertain only to the filing of your federal income tax return."

    Caution:

    Be reminded that because this case involves an SSN of undetermined ownership, we cannot disclose any further information. Also, be careful not to indicate any pre-determinations you may have arrived at based on the answers you received.
