4.4.1  Introduction

4.4.1.1  (05-19-2009)
Introduction

  1. This handbook contains instructions for Examination personnel on the use of the Audit Information Management System (AIMS) and the processing of cases.

  2. The AIMS IRM is divided into chapters based on topics such as Openings, Closings, Transfers, Updates/Corrections, etc. Exhibit 4.4.1-1 contains a Reference Guide, which should be used as a starting point when researching AIMS issues. The goal is to list all possible topics of interest and references to the appropriate IRM section.

  3. Examination managers are responsible for the timely implementation of all AIMS changes and manual revisions that affect their operation.

  4. Any changes or revisions where their effect/impact cannot be determined, will be referred to the AIMS Coordinator in the campus or the AIMS/ERCS Analyst in the Area Office for clarification.

4.4.1.2  (05-19-2009)
Description of AIMS

  1. AIMS, the Audit Information Management System is a computer system used by Appeals, Examination (LMSB/SBSE/W&I), and TE/GE to control returns, input assessment/adjustments to Master File and provide management reports.

    1. While the return is charged to Examination, the AIMS data base tracks its location, age, and status.

    2. Information on the management reports can be found in IRM 4.4.27, AIMS/Processing Handbook - Reports.

  2. The AIMS base has been consolidated into one Individual Master File (IMF) data base and one Business Master File (BMF)/Non-Master File (NMF) data base. It appears to the user that there is only one data base. You can view all returns on AIMS using CC AMDIS(A) without having to use CC CMODE.

4.4.1.3  (05-19-2009)
AIMS/Master File

  1. Inputs to AIMS cause the following changes to Master File.

    If you: Then Master File is updated with a:
    Input an AM424 TC 424 & L freeze
    Receive an opening record TC 420
    Update a statute date using AMSTU or AMCLS TC 560 (with a blocking series of 775) and/or new ASED
    Input an AMSOC for a transfer New PBC code in the first 2 digits of the DLN of the most recent TC 42X.
    Input an AMSOC for a non-examined closure TC 421 - in some cases a TC 59X is generated if certain disposal codes are input.
    Input an AMCLSE TC 30X - Disposal codes other than 07, 11 or 12 if an AOC is present generates the TC 421.

90-Day Letter - See IRM 4.8.9, Statutory Notices of Deficiency Issued by Area Office, and IRM 4.10.10, Campus Operations, for information on 90-Day Letters.

Abstract Code - The abstract code represents the 3 digit IRS No. that is found on Form 720, Excise Tax Return. It is displayed on AIMS in the Activity Code field. When excise tax returns are examined and there is an adjustment to the amount reported under an abstract code, Item 15 on Form 5344, must be completed to update the Master File Abstract field. Unless the examination is for a claim, each abstract code examined must be reflected in Item 404 on Form 5344. Do not make any entries in Item 404 for the examination of a claim. The code that is displayed on the AMDIS is the code used when the requisition was input and is not overlaid when a full data base is received. (L13-E38b/P1L7).

Account Receivable Dollar Inventory (ARDI) Code - Code used by Appeals and TE/GE to record the type of advance payment received for the tax period being closed. (P2-L19)

Activity Code (ACTY-CD) - A 3 digit code that categorizes classes of returns (referred to as the Abstract Code for Forms 720). When establishing a return on AIMS, enter an estimated activity code on Form 5345. The opening record sent to AIMS from Master File will overlay the estimated code with the correct code with the exception of MFT 03 - the activity code input on the requisition will not be overlaid. The Activity Code generated by Master File should not be changed unless one of the exceptions to the rule below applies:

EXCEPTIONS
SFR's - Since no return was filed, the opening activity code is a guesstimate of the correct code. The activity code must be updated based on the figures on the RAR, before the case leaves the group.
Activity Code 203 (no balances sheet or 0 assets) returns - if the return is not correctly coded with a 203, update to correct activity code. A change in coding for Activity Code 203 has been scheduled for 1/1/2009.
Activity Code 231 returns - cases must be updated out of Activity Code 231 before closing.

Activity Codes 224, 287-290, 480-483, 489, 497, 498 and 992 are for non-taxable returns such as Forms 1041, 1065 and 1120S. EGC 2XXX can only control the following activity codes, Form 1040-All, Form 1041-495-496, Form 1065-473, 480-483, Form 1120-203, 209, 213, 215, 217, Form 1120S -202, 287-289. (L13-E38b/P1-L7/A-CIS/SSIVL) See Exhibit 4.4.1-2 for a complete list of Abstract/Activity Codes.

Activity Indicator (ACT-IND) - If present, it means that an update of some kind has been done on the AIMS module since the last weekly analysis and extract. This field is present on the AMS 7108 and 7109 tapes and is used by programs that use these tapes to identify accounts that were updated since the last weekly tape. After the weekly run the indicator is reset to zero. (P1-L21)

Adjusted Taxable Gifts (ADJ-TAXABLE-GIFTS) - Addition of this field to AIMS and A-CIS is scheduled for January 1, 2010. This is the Adjusted Taxable Gifts amount from the Form 706. If available at the time of implementation, this information will be populated for returns filed prior to implementation. (/P2-L13/A-CIS)

Adjustment Amount - See Examination Adjustment Amount.

Aging of the AIMS data base - See Exhibit 4.4.1-3.

Aging Reason Code (AGING-RC) - 2 digit code used to identify special cases on AIMS. Can be input/updated using CC AM424, AMSTU, AMCLSE, AMAXUE. See Exhibit 4.4.1-4.(L16-E50/P1-L17/A-CIS/SSIVL)

Agreements - See IRM 4.4.12 for information on agreements.

AIMS Assignee Code (AAC) - The AAC is the coding mechanism that Examination uses to assign work. It is a 12 digit field made up of three parts. The first three digits represent the Primary Business Code (PBC). This identifies the operating division such as Appeals, LMSB, SB/SE, TE/GE, and W&I. The second five digits represent the Secondary Business Code (SBC). The last 4 digits represent the Employee Group Code (EGC). See Document 6036, Examination Division Reporting System Codes Booklet, for a complete list of PBC's and SBC's. For a complete listing of EGC's, visit the AIMS web site at http://sbse.web.irs.gov/AIMS/docs/EGCbyPBC.xls .

AIMS/Exam-Results - See Exam Results

AIMS Freeze Code - A freeze code is used to prevent the update and/or closing of AIMS bases until the freeze code is removed. The freeze code field displayed on the AMDISA is two spaces. The first space contains all freeze codes with the exception of bankruptcy codes. The second space contains an "X" or "Y" which are the two valid bankruptcy codes. Both fields may be present. See Exhibit 4.4.1-5.. Additional instructions on AIMS freeze codes appear in IRM 4.4.34, Updating/Correcting AIMS Data Base. Instructions about Master File freeze codes can be found in Doc. 6209, IRS Processing Codes and Information. (L12-E35/P1-L14)

AIMS Open Control Number (AIMS-OPEN-CTRL-NUM) - If no return is requested an AIMS Open Control Number is not generated.
For Master File AIMS opening, the AIMS Open Control Number is a 12 digit computer generated number. Returns in Centralized Files and Scheduling are filed on the shelves in ascending AIMS control number sequence. The AIMS Open Control Number was previously displayed on IDRS command codes such as IMFOL and BMFOL. Since the implementation of the AIMS Assignee Codes, the AIMS Open Control Number is only displayed on CC AMDIS(A) and the Form 5546. (L4-E15/P1-L17)
For records opened prior to 1/1/2007:
1st to 3rd = 000
4th - 6th = PBC
7th - 12th are sequential starting at 000001 for IMF and 500000 for BMF.
For records opened after 12/31/2006 :
1st to 3rd = PBC
4th = year digit
5th - 6th = weekly cycle of opening (01-52)
7th to 12th = sequential starting at 000001 for IMF 500000 for BMF
Example: Control Number 296705000025 means - 296 (PBC) 7(2007) 05 (5th week) 000025 (25th record opened since the last initialization of the program).
For NMF Records (CC AMNON), the control number is computer generated using the input PBC and the form number. Example: If Area 205 established a Form 1042 on AIMS using AMNON, the AIMS Control Number would be displayed as: 000205104200.

AIMS Opening Source Code - See Opening Source Code.

AIMS Reports - See IRM 4.4.27.

AIMS Serial Number (AIMS-SER-NUM) - (Also known as the AIMS OPEN CONTROL NUM). See AIMS Control Number.

Alpha Statute Codes - 2 digit alpha codes located in the "day" portion of the ASED indicate there are special circumstances surrounding the statute. If there are alpha codes (other than EE) on a skeletal record, when a full record comes down from Master File the MM and YYYY portion of the ASED will be populated with the month and year from the Master File ASED. If the alpha code is "EE" , the DD portion of the ASED will also be populated with the Master File ASED. The Alpha Statute Codes can be updated using CC AMSTU and AMCLS. See IRM 25.6.23 for instructions on the use of Alpha Statute Codes. (L12-E34/P1-L3)

AMDIS(A) Screen Prints - Visit the AIMS web site at: http://sbse.web.irs.gov/AIMS/docs/AMDIS-2008.DOC .

Amended Return - Amended returns may be referred to Examination for consideration. All assessment (overassessment) documents are usually in the administrative file. However, the file must be checked to determine if a change in tax liability has previously been made as evidenced by a CP36 or CP193, notices with transaction codes (TC) 290 or 291, or computer notices indicating an adjustment has been made. If these forms are not included and doubt exists, a transcript of account should be secured. Once it has been determined that the adjustments were not made, any necessary adjustments to refundable credits on individual or corporate returns, except estimated tax payments or credits must be reflected in the examiners report.
If an amended return is filed with the examining officer and an examination is not warranted, process the amended return directly to the campus for input to the master file following secured delinquent return procedures in IRM 4.4.9. Do not establish on AIMS. If the amended return was filed as a result of an on-going examination, see Amended Return Amount.

Amended Return Amount - Form 5344, Item 415. See IRM 4.4.12, Examined Closings.

Note:

Credit for Amended Returns - If a taxpayer sends a taxable amended return that is the direct result of an ongoing examination (TC 42X present prior to the posting of the TC 290) to the campus and the tax is assessed as a TC 290, Examination is to enter in Item 415, Amended Return Amount of the Form 5344, the amount of the tax assessed adjusted by credits. Before 1/1/1999, Examination did not receive "credit" for this type of adjustment.

(P2-L21)

Amount Claimed - See Claim Amount

Appeals Office Code (AOC) - 3-digit code that is required when closing returns to Appeals as appealed/nondocketed (1XX) or petitioned/docketed (2XX). (P1-L12/A-CIS/SSIVL) See Exhibit 4.4.1-6)

AMSOC Transfer Date (AMSOC-TRANSFER-DATE) - The date that the transfer was input (CC AMSOC DC 30). (P1-L10/A-CIS)

Assessment Statute Expiration Date (ASED) - The date that the assessment statute expires. For MF records, the ASED is sent from Master File to AIMS on the AIMS opening record. Exception: MFT 06 - Since the ASED at Master File is blank for MFT 06 records, AIMS sets the ASED by adding 3 years to the Return Received Date that is on the AIMS opening record. An "X" after the date indicates that the statute has been updated using CC AMSTU or CC AMCLSE. An "R" indicates a restricted consent. A "U" is used to removed the restricted consent indicator. If the statute date is input using CC AMSTU and the statute does not contain alpha codes, and it does not match the current AIMS ASED, a TC 560 is generated with a blocking series of 775 and sent to Master File. If the TC 150 at Master File is an Substitute For Return (SFR), the TC 560 will post but it will not update the Master File ASED field. (L12-E34/P1-L3/A-CIS/SSIVL)

Asset Class Code - Code generated by Business Master File used by AIMS to generate the Activity Code for corporate returns. Displayed on BMFOLR and AMDISA (P2-L5/A-CIS)

Audit Category Codes/Codes - Entered on tax returns by campus personnel. Some audit codes cause automatic AIMS openings while other audit codes are just displayed on the F5546 if a return is opened on AIMS. (L21-E63/P2-L5/A-CIS)

Form 1040 See IRM 3.11.3

Form 1041 See IRM 3.11.14

Bankruptcy Processing Procedures - If bankruptcy proceedings are against both Joint Return Deficiency taxpayers, research the Master File to ensure that transaction code (TC) 521 has been input to release the bankruptcy freeze. If the TC 521 has not been input and the taxpayer is still in bankruptcy, any assessment made could be illegal. If TC 521 is not present on the module, coordinate with Technical Services

Bankruptcy Indicators - There are two fields on AIMS that identify taxpayers in bankruptcy. See AIMS Freeze Codes U and X and Collectibility Indicator Code (1=Bankruptcy). (L7-E23/P1-L22/A-CIS)

Beginning Overlapping Period - The beginning date of the overlapping interest period used in the net rate computation. Item 53 on the Form 5344. See IRM 4.4.12, Examined Closings.

Block - Returns or documents grouped together for filing purposes. The ninth, tenth and eleventh digits of the DLN indicate the blocking series where the return is filed.

Blocking Series - A 3 digit number required for all examined closures (P36-38 on Form 5344) that identifies the type of source document filed under the DLN. Master File uses the blocking series to determine whether to generate CP notices and the control DLN indicator "X" . See Exhibit 4.4.1-7. or for additional information visit the AIMS website at: http://sbse.web.irs.gov/AIMS/docs/BlockingSeries-Exam.xls

Business Master File (BMF) - The file containing information about taxpayers business, estate, gift and trust returns and related documents.

The check digit ensures that the correct TIN has been input and should always be used if available. (L2-E6/P1-L1)

CIC Indicator - A one digit code used to identify Coordinated Industry Cases. This indicator is set when a "P" is entered in the LMSB/CIC box on the Form 5345-B. The indicator can also be set after a case is opened on AIMS by entering an "L" on the CIC line of the Form 5349. The literal CIC-CASE will be displayed on CC AMDISA if the indicator is set. (P1-L3/A-CIS/SSIVL)

Claim - Term used when taxpayer files a subsequent return requesting a refund or abatement of previously assessed tax.

Claim Amount - Dollar amount of claim for abatement or refund.

Claim Date (CLAIM-DATE) - The claim date is generated when a claim amount is input. The Claim Date cannot be input when the case is established using AM424. The current date is generated.

Cross-Reference Document Locator Number (XREF-DLN) - is the DLN that is generated when a CC AM424 is input. This number is replaced with an incomplete DLN that AIMS creates if a partial assessment is input and also when the record is closed. The incomplete DLN is sent to the end of day program as part of the TC 300 record. The DLN is completed by the end of day program and becomes the DLN of the TC 300/TC 421. This is the reason why the AIMS DLN will not match the DLN that posts to Master File. (P1-L15)

FUTA State Code - "T " = tax followed by 2 digit state code; or "W" = wages followed by 2 digit state code. See Exhibit 4.4.1-21.

Grade of Case (GR-CASE) - A four digit field input from Item 32, Form 5344 used to reflect the grade level of difficulty of an examination. If a "+" is displayed on line 11 of the AMDISA after the grade of case, it signifies that an "R" , the related return indicator, was input. See Document 6036 or IRM 1.4.40 for the list of valid codes. (P2-L11/A-CIS)

Gross Estate Amount - Addition of this field to AIMS and A-CIS is scheduled for January 1, 2010. This is the gross estate amount from the Form 706. If available at the time of implementation, this information will be populated for returns filed prior to implementation. (P2-L13/A-CIS)

IMF Issue Code - All individual returns closed as a no-change, require entry of an IMF issue code to allow AIMS to record the issues considered during the examination and no-changed. The information is sent to Master File and also captured by EOAD. You can review this information using CC IMFOLZ/BMFOLZ. If a subsequent return is open on AIMS, the F5546 will display the IMF Issue Codes. This will allow classifiers to consider the issues that were no-changed in the prior examination when determining whether the return currently under consideration should be selected for examination. This process reduces unnecessary taxpayer contacts and prevents repetitive examination of the same issue. See IRM 4.4.12 for more information and IRM 4.10.16-2. You can find the most current list of IMF Issue Codes at the AIMS website: http://sbse.web.irs.gov/AIMS/default.htm http://sbse.web.irs.gov/AIMS/default.htm .

IRS Employee Code - AIMS - This indicator is automatically set to an "E" when a case is opened on AIMS if the Master File IRS Employee Indicator is set. An indicator of an "E" will prevent the case from closing. The indicator is changed to a "C" by CCP (or TS if an unagreed case) when they determine that all the necessary information has been sent to the IRS Employee Audit Coordinator and the case is ready to be closed. If the indicator was set incorrectly, the indicator can be removed by inputting an "R" . (P1-L18/A-CIS)

IRS Employee - Master File (MF/IRS EMP) - If the primary taxpayer is the employee the indicator of a 1 will be set and "MF/IRS EMP-PRIMRY SSN" will be displayed on AMDISA. If the secondary taxpayer is the employee the indicator of a 2 will be set and "MF/IRS EMP-SECOND SSN" will be displayed on AMDISA. If both taxpayers are employees, the indicator of a 3 will be set and "MF/IRS EMP-BOTH TPS" will be displayed on AMDISA. (P1-L18/A-CIS)

Individual Master File (IMF) - The file containing information about taxpayers individual returns and related documents.

Informant Claim Indicator (ICE-IND) - The ICE Indicator or a "1" is placed on a case using AM424, AMNON or AMSTU and prevents the closure of the case (Status Code 8X or 90) before the ICE Coordinator has the necessary information from the case file. The ICE Indicator should only be set and removed by the Informant's Claim Coordinator located at Ogden campus. . Effective 1/1/2009 "2" is being added as new value. When a case is ready to be closed (Status Code 90) the ICE Coordinator will update the indicator to a "2" which means "ready for closing" . A value of "1" should remain on the case when Exam is closing a case to Appeals. The indicator is not on ERCS but is on A-CIS. The ICE Coordinator's name and number are listed on the AIMS website contact listing under the Ogden campus tab which can be found at: http://sbse.web.irs.gov/AIMS/docs/ContactList.xls . (P1-L18/A-CIS/SSIVL)

Injured Spouse Cases - Injured spouse claims, if filed with the campus, are worked in the Adjustments area even if a TC 420 is present. Adjustments will secure a copy of the return from Examination or contact the taxpayer for a copy if not readily available in Exam. See IRM 21.4.6, Refund Offset.

Missing Returns - See IRM 4.4.20, Missing Returns and Error Account.

Multiple Return (Tax period) Examinations - In multiple return examinations, the majority of the workpapers are filed with the latest deficiency tax period. To identify the location of the workpapers, TC 971, Action Code 057 was activated. This action code must be input if the work papers are not filed behind the refile DLN of the case being closed. This TC 971 will not create an A freeze at Master File. This will also cause the return to appear on the CSED listing which prevents the returns from being destroyed prematurely.
Example 1: Tax periods 200512, 200612 and 200712 were examined. 200512 and 200612 resulted in deficiencies, 200712 was no changed. Of course copies of the RAR and 90-Day letter are filed with each tax period but the workpapers are filed with the 200612 return (the latest deficiency tax period). Immediately after the 200512 and 200712 cases are closed, status code 90, a TC 971, AC 57 must be input with the SSN, tax period 200612 and MFT 30. This will alert anyone trying to locate the workpapers for these years, that they are filed with the 200612 tax period.
Example 2: A Form 1065 and a related Form 1040 for 200712 is examined resulting in a deficiency for the Form 1040. All the workpapers are filed with the Form 1040. Immediately after the 1065 is closed, status code 90, a TC 971, AC 57 must be input with the SSN, tax period 200712, and MFT 30. This will alert anyone trying to locate the workpapers for the Form 1065 examination, that they are filed with the 200712 Form 1040.

NAICS Code - The North American Industry Classification Code. For MFT's 02, 06 and 30 NAICS codes are valid for tax periods 199812 and subsequent.

Non-Master File (NMF) - Non-Master File is a manual accounting system controlling certain types of returns that are not processed through the computer system to Master File. Research can be conducted on NMF account using ANMF. Recordation of adjustments, billing of assessments and refunds of overassessments are performed manually by the campus. A non-master file account established on AIMS is not subject to many of the same computer checks of a master file account. A non-master file account can be established on AIMS with incorrect information because the account information is not compared to a computer file, such as is with Master File, or the manual ledger account cards at the campus. When establishing a non-master file AIMS record, you should ensure the taxpayer and tax account information is correct. Form 5354, Examination Request Non-Master file is used to establish NMF AIMS control on AIMS. The command code is AMNON.

Bypasses UPC 150 RC 2
Bypasses UPC 168 RC 23
Bypasses UPC 189 RC 0
BMF: Do not use PC 9 - BMF automatically generates FTP from RDD.

Processing Campus Code (PCC) - A three digit number used by EGC's 1XXX and 2XXX to identify the Centralized Case Processing site that has control of a case in Status Code 51-59. This code must be present when a case is updated to Status Code 51 if the prior status code is not 5X. This code will remain on the data base when a case is closed but will be deleted if a case is updated to a status code less than 51. If the status code is 51-59, some AIMS reports/tables will be created based on the PCC rather than the area office. The PCC can be updated from one PCC to another PCC after the initial setting of the PCC. (P1-L23/A-CIS/SSIVL)

When a case is updated on ERCS to a Status Code 51, ERCS will automatically update the PCC to: If the PBC=
17 212-214 or 315
29 301-306
49 201-207

Project Code - A 4 digit number indicating that a case belongs to a special program which allows monitoring of the program by project code. AIMS reports can be generated for a given project to measure the total number of returns, examination time, results, etc. If a project code is input that has not been validated, the AIMS base will reflect the new project code but the project code will be zeroed out on Tables 36 & 37 and A-CIS. For SB/SE & W&I, local definition project codes will be zeroed out when transferring from one area to another. For LMSB cases, the project codes will be zeroed out when transferring from 3XX to a non-3XX PBC. Effective 1/2/2009 - the project code cannot be corrected on a record with a status code greater than 79 if the case was closed in a prior fiscal year and the date of the correction is after the end of the extended fiscal year. Project Codes 101-104, 106, 107, 109, 110, 113, 114, 116, 118-121, 122, 205, 209, 210, 225 and 401 are not valid for tax periods after 199012. For a complete list of validated project codes see: http://sbse.web.irs.gov/AIMS/docs/ProjectCodes.xls .(L22-E66/P1-L14/A-CIS/SSIVL)

Push Code - A 3 digit code (010, 019, 020, 021, 023-041, 049, and 121/BMF) used to establish AIMS controls for unfiled returns, substitute for returns and delinquent returns secured by examination. If a push code is not used on a requisition for an unfiled return, the requisition will reject. By using a push code, the computer will not reject the account. The TC 424 will remain at Master File and the skeletal record will remain on AIMS until either a TC 150 posts or 26 months (90 days for Push Code 010) unless deleted or replaced by a full record. Skeletal records with push codes can be deleted on the day of input or after 15 days from date of input except Push Code 036 - it can be deleted on the day of input or after 30 days from date of input. If EGC = 1000 or 2000 the only valid push codes are 024-040. (L22-E65/P1-L14/A-CIS/SSIVL) See Exhibit 4.4.1-14.

Record Type Code - A two digit code used to indicate the type of AIMS record.

  F0 = Full Account
  F1 = TC 424 Skeletal Record
  F2 = Residual Transfer Record (Obsoleted Jan. 2004)
  F4 = TIN Change Record
  F5 = Large Case Related Record (Obsoleted)
  F6 = Record Retention Agreement Record (Obsoleted Jan. 2004)

Record Retention Agreement Record (F6 Record) - Obsolete as of JAN. 2004. Established on AIMS using CC AM424R and deleted using CC AM424E.

Reference Returns - When a return is needed for reference or information purposes and an print is not sufficient, it will be requisitioned using Source Code 45. See Exhibit 4.4.1-15 for Reference Return Procedures.

Refund Statute Expiration Date (RSED) - See IRM 25.6.23, Examination Process - Assessment Statute of Limitations Controls.

Refile DLN - A refile DLN is assigned to a case after examination (TC 30X) or adjustment (TC 29X) action. This number can be researched by requesting a transcript of the account. An "X" after the DLN indicates the original return is filed behind the refile DLN. Cases closing with an electronic print (Blocking Series 3XX), will receive a refile DLN but it will not have an "X" after it. See Exhibit 4.4.1-7.

Refund to Related Taxpayers - See IRM 4.4.3, Adjustments-Miscellaneous.

Related Return Section - Information collected on all returns (excluding EGC 58XX) to analyze the productivity of examinations of related returns. See IRM 4.4.12, Examined Closing. (P3-L16,17/A-CIS)

Reopening Indicator (REOPENING-IND) - Present if CC AMSTUB or AMSTUR is input. (P2-L7/A-CIS/SSIVL)

Indicator Definition
0 Account never reopened
1 Account reopened using AMSTUR
2 Case backed down from Appeals using AMSTUB
3 Case has been reopened & backed down

Report Extraction Code/Indicator (RPT-EX-CD) - Used to identify how the case is to be extracted for AIMS reports. When CC AMAXU/AMCLSU is input, the reports extraction code is set so that the corrected record is re-extracted for AIMS reports. This field is called the Report Extraction Indicator in the AIMS programs. (P3-L9)

Code Explanation
0 Extract record/original closure or reclosure (Status Code greater than 79)
1 Record previously extracted for Exam reports
2 A correction (CC AMAXUE/AMCLSU) has been made to a record already extracted for Exam. Record will be re-extracted during next extraction cycle but the initial extraction cycle will not change.
3 Delete record if closed in same fiscal year or establish a history record for netting purposes/record backed down (CC AMSTUB/R) to an Exam inventory status
4 Record previously extracted for Appeals reports
5 A correction (CC AMAXUA/AMCLSU) has been made to a record previously extracted for Appeals
6 A correction (CC AMAXUE/AMCLSU) has been made to a record previously extracted for Examination and Appeals

Report Extraction Cycle (RPT-EX-CYC) - Month/Year of closing (original or reclosure). Does not get updated when a CC AMAXU/AMCLSU is input. Data bases are aged based on the report extraction cycle. (P3-L9)

Report File Source Code - The AIMS reports programs convert the File Source Code and generates a Report File Source Code. This is the File Source Code that appears on A-CIS.

Report File Source Code TIN Format
0 nnn-nn-nnnn
1 nnn-nn-nnnn*
2 nn-nnnnnnn
4 nnn-nn-nnnV
5 nn-nnnnnnnN
6 nnn-nn-nnnnN
7 nnnnnnnnn-D

Reprocessing Returns - Generally reprocessing is necessary because a return was processed to the wrong tax period or to the wrong TIN. See IRM 4.4.3.

Residual Transfer Records (F2 Record) - Due to the centralization of the AIMS data base in January 2004, there are no longer residual transfer records. Transfers take place immediately and a residual record is not created.

Retention Register - Accounts are removed from Master File due to inactivity. The Master File has a limited capacity, thus, accounts that are unlikely to be needed again are removed to a less accessible file. The basic criteria for removal of a module to the Retention Register are: (1) the assessed module balance is zero and the last transaction (including the return) has been posted 51 or more months; (2) the assessed module balance is credit and the last transaction (including the return) has been posted 60 or more months. Transactions cannot post to the Retention Register therefore, if the account is to be put on AIMS, the module must be brought back to Master File. When an account with an ELF return is put on retention, you can no longer retrieve a TRPRT of the return. Cases that were recently moved to retention can be brought back using CC IMFOLB/BMFOLB. Check IMFOLI/BMFOLI to see if CC IMFOLB/BMFOLB (earliest tax period is 199812) can be used to bring account back to active Master File status. Effective 1/2/2008, if the account is on the recoverable retention register, AIMS will block the establishment of the case until the account is brought back from retention.

If the MFT and Tax Period is then, the account
displayed on the IMFOLI/BMFOLI with no R to the left of the MFT is active and you can requisition the return
displayed on the IMFOLI/BMFOLI and there is an R to the left of the MFT is not active and CC IMFOLB/BMFOLB must be input to bring the account back to active status - once back to active you can requisition the return
displayed on the IMFOLV/BMFOLV and it was moved to retention after 200112 is not active and CC IMFOLB/BMVOLB must be input to bring the account back to active status - once back to active you can requisition the return
displayed on the IMFOLV/BMFOLV and it was moved to retention before 2002 is not active and can only be brought back using the Retention Register Reinstatement Procedures. See Exhibit 4.4.1-16..

See Exhibit 4.4.1-16,Retention Register Reinstatement Procedures, for instructions on bringing accounts back from retention.

Retention Register Indicator (RETN-REG-IND) - Set when a TC 424 rejects due to UPC 197 or 347 which means the account is on retention. Unlike other TC 424 rejects, the data base will not be immediately deleted. When the case appears on the AIMS Weekly Update Report, steps must be taken to request that the account be brought back from retention. 56 days from the opening creation date another TC 424 will be automatically generated and every two weeks thereafter until the opening creation date is greater than 3 months from the current date. See Exhibit 4.4.1-16.Retention Register Reinstatement Procedures. If the account still has not been brought back from retention after 3 months, an AIMS Weekly Update Report record with condition code 24 will be generated and the record will be aged off of the AIMS data base. Effective 1/1/2008, a CC AM424 cannot be input if IMFOLI/BMFOLI indicates that the account is on recoverable retention. The account must be brought back from retention before the AM424 is input. (P1-L8/Exhibit 4.4.1-16)

Return Condition Code - (Also known as Computer Condition Code) These codes are assigned by tax examiners or are computer generated at the time a return is filed. Presence of these codes initiates action as explained in Document 6209, ADP and IDRS Information.

Return Form Number (RET-FORM) - See Exhibit 4.4.1-13. for a list of forms that are valid on AIMS and their respective MFT, NMF or activity code. (L2-E4/P2-L3/A-CIS/SSIVL)

Return Posting Year (RET-PSTNG-YR) - The year the original return posted to Master File. (P1-L16/A-CIS)

Return Requisition Indicator - Indicates whether the return, charge-out and labels were requested on the AIMS opening (CC AM424), a follow-up request (AMRET), DIF opening or automatic opening. If you requested the return during on the original requisition and have to input a follow-up using CC AMRET, you must wait 60 days from the AIMS Creation Date before you can input the AMRET. If you did not request the return on the original requisition you do not have to wait 60 days to input a CC AMRET follow-up request. (P2-L8)

If: Then input:
return, F5546 and labels are needed blank
no-return is needed but you want F5546 & labels 1
no-return, no-F5546 and no-labels are needed 3
the return is requested and the return is ELF or MeF, AIMS changes the Return Requisition Indicator from a blank to a 5. 5

Return Received Date (RET-RCVD-DT) - For timely filed returns it is the due date of the return. Example: Form 1040 due April 15 will be displayed as April 15 of the appropriate year even if the return was filed before the due date. For late filed returns it is the received date stamped on the return. For SFR cases (Push Code 036), it is the date of the TC 424 that contained the Push Code 036. (P1-L16/SSIVL)

Revenue Base Protection - If a taxpayer files a claim for refund, Examination gets credit on the Exam tables by entering the amount of the claim, the time spent on the claim and the type of claim. See the Revenue Base Protection section in IRM 4.4.12, Examined Closing. (P3-L14/P3-L3-L15)

SC-Transferred From - See Transfer Terminal Code. (P1-L10)

Schedule C/F Indicator (C-F-IND) - For records opened on AIMS after 12/31/2007, if there is a Schedule C or F filed with the original return, Master File will set this indicator on the AIMS opening record. Once this indicator is set at Master File it does not change. (P2-L5/A-CIS).

Schedule C/F Value Definition
0 no Schedule C/F filed
1 Schedule C but no F
2 Schedule F but no C
3 both and C dominant
4 both but F dominant

Schedule H, Household Employment Taxes - See IRM 4.4.10.

Secondary Business Code (SBC) - See "AIMS Assignee Code" (P1-L10/SSIVL).

Secondary SSN - See " Secondary Spousal SSN" .

Short Closing - Another term for the non-examined closing of a return via CC AMSOC. See IRM 4.4.21, Non-examined Closings.

Skeletal Accounts (F1 Records) - AIMS creates a skeletal record when a CC AM424 is input, showing the requisition and limited taxpayer information. Once the request goes to Master File and is matched, Master File sends an opening record to AIMS and the account becomes fully established. Once fully established, AIMS sends a TC 420 back to Master File. The EGC and activity code can be updated on a skeletal account using CC AMAXU. All elements, except the statute date, can be updated using CC AMSTU. A listing of accounts that remain as skeletal records in excess of a specific number of days is generated quarterly. Also refer to the Aging Chapter for information on how long a skeletal account remains on AIMS.

Social Security Number - The nine digit account number with a format, XMM-DD-YYYY, used to identify individual taxpayers. It is used on the Individual Master File.

Social Security Tax Rates (FICA and SE) - See Document 6209

Sort Codes - A two character field used to sort output of Forms 5546. (L16-E25a/ See Exhibit 4.4.1-17.)

Sort Keys - A three character field used to sort Forms 5546 and labels. (L16-25/ See Exhibit 4.4.1-18.)

Source Code - A two digit code used to indicate the source of the examination. Form 5348 or 5349 (CC AMAXU) can be used to request a change to a source code but - the source code should rarely be changed. See 4.4.34, Update/Correcting, Exhibit 4.4.1-19) and/or the Source Code Document posted to the AIMS/ERCS/SETTS website.(L15-E22/P1-L4/A-CIS/SSIVL).

Special Estimated Tax (SET) Payment Program - Section 6077(a) of the Technical and Miscellaneous Introduction Revenue Act of 1988 (TAMRA), added Code Section 847, Special Estimated Tax Payments, effective for tax years beginning after December 31, 1987. Section 847(2) requires certain insurance companies to make a special estimated tax payment in an amount equal to the tax benefit derived from the additional deduction permitted under Section 847. Section 847(3) requires the companies that are allowed the additional deduction to establish a special loss discount account.
Form 1120PC filers will claim the credit on a specific line as designated on the tax form. Other 1120 filers electing the provisions under this section may write on top of the form " Section 847" and show the amount of the credit. Estimated tax payments may also be received for this credit.
Procedures: MF is not programmed to accept the special estimated tax payments from these taxpayers and cannot handle the disposition of the payments over the required 15 year period, the NMF Accounting function maintains and monitors these payments through the NMF 4615 Account.
When such payments are received, the Form 3244 will be prepared reflecting "IRC 847 Payment-Apply to NMF 4615 Account." The payment posting voucher will be sent to the Accounting function by the operation that handles payment processing. If it is determined that an IRC 847 special estimated tax payment has posted to MF, transfer the payment to the NMF 4615 Account via Form 3809.
The Accounting function will handle the transfer of the special estimated tax payments from NMF to MF when such payments must be used by the taxpayer to offset additional tax in accordance with the requirements of Section 847.

Special Handling Message Codes 042-048 - (Item 9, Form 5345 or Item 21, Form 5354) are treated in the same manner as a push code except, it also generates processing instructions on Form 5546. These codes are used in the campus in the association of requests for multi-year case files before delivery to examiners and also to indicate that the attached return requires special handling. These codes are specified by the Chief, Campus Classification. (L23-E34)

Special Messages - Special messages are generated on the Form 5546 as a result of certain conditions, See Exhibit 4.4.1-20., Special Messages on Form 5546. These messages are computer generated on the Form 5546 to assist the Files personnel in the campuses in the routing of the returns. (L11-E16)

Special Return - A return that contains one or more of the identifiable features listed in Part IV of the IRM. These returns must be delivered for screening or classification regardless of their DIF Score. In most cases the Audit Code is what identifies the case as a special return.

Spousal Change Indicator - Set when there has been a change in spouses to ensure both taxpayers on a joint return receive all notices, correspondence, etc. (P1-L9)

Spousal IRA Code (Spouse-IRA-CD) - Indicates the type of IRA account as indicated on the tax return. (P1-L8)

2 = Secondary spouse in joint return has IRA
3 = Both have IRA plans
4 = IRA notice issued
5 = IRA notice issued to primary account
6 = IRA notice issued to secondary account
7 = IRA notice issued to primary and secondary account

Spouses-SSN - Present if a joint return was filed. Also known as secondary spouse SSN. (P1-L8/SSIVL)

State Alpha Codes - When entering a taxpayers address, always use the two digit alpha state code. ( See Exhibit 4.4.1-21.)

Status Codes (CURRENT-STATUS-CD/DATE) - Two digit code used to identify the location of a return. See Exhibit 4.4.1-22.(L20-E30/P1-L13/A-CIS/SSIVL)

Statute Codes - See IRM 25.6.23.

Statute Consent Code - See Consent Code.

Statute Date - See Assessment Statute Expiration Date.

Statute Extraction Indicator (STATUTE-XTRCTN-IND) - "1" means that the record has been extracted to a statute listing. This indicator causes the "R" to be displayed on subsequent statute listing if the case still meets the criteria. Each time the statute or EGC is updated, the indicator gets reset to a "0" . This is done so a case that appeared on a prior statute list but with a different ASED or in a different group does not get designated as a record that was on the previous statute report. (P1-L9/A-CIS/SSIVL)

Statute Extension Type - Statutes that are not all numeric are actually stored in a separate field on AIMS called the Statute Extension Type field. They are displayed in the same field as the Assessment Statute Date field. (A-CIS).

Statutory Notice of Deficiency (SNOD) - See 90-Day Letters.

Substitute for Return (SFR) - A procedure by which Examination is able to establish an account by posting a computer generated TC 150 when the taxpayer refuses or is unable to file. See IRM 4.4.9, Delinquent and Substitute for Return Processing for more information.
For IMF returns, an SFR can be identified by a TC 150 with a DLN of XX-210-XXX-(000-299)-XX-X (paper SFR's) or XX-210-888-000-XX-X for computer generated SFR's using AM424 with Push Code 036.
For BMF returns, an SFR can be identified by the presence of CCC 4 or a DLN XX999-999-999-XX-X for computer generated SFR's using AM424 with Push Code 036. The MFT's that are valid with the computer generated TC 150 are: 01, 02, 03, 04, 05, 06, 07, 09, 10, 11, 12, 14, 16, 33, 40, 51, 52, 58, 60, 63, 64, 77 and 78.

Survey Reason Code (SURVEY-REASON-CD) - Created 1/1/2008, used to identify why a return was surveyed with a Disposal Code 31 or 32. The SRC is required on LMSB returns closed with DC 31 or 32. The SRC is optional on SBSE returns closed with DC 31 or 32. One of the following values must be entered on the closing form to the right of the disposal code. Values are:

A No large unusual questionable items
B No change in prior year
C Beyond cycle (includes statute issue)
D Lack of resources
E Other
F-Z Reserved

(P2-L4/A-CIS/SSIVL)

Suspense Code (SUSP-CD) - A one digit computer generated code used to identify returns in a status code 14, 3X or 44 which are categorized as suspense statuses. Suspense Code 1 is generated when cases are established (CC AM424/AMNON) on AIMS in a suspense status code. Suspense Code 2 is generated when a case is updated (CC AMSTU/AMSOC DC 30) to a suspense status code. Once set a suspense code cannot be removed. See the Status Code document that is posted to the AIMS/ERCS./SETTS website to see which status codes set the suspense code. (P1-L7/A-CIS)

Tax Agency Disclosure Codes - See IRM 4.4.28, Revenue Agents Reports (RAR's) Sent to States.

Tax Class - The third digit on the DLN that identifies the type or return or document that was filed or processed. All IMF returns and documents have a tax class of "2" . See Doc 6209 for complete list.

Tax Period - The period of time for which a return is filed. A six digit code is used to indicate the end of the tax period for a given return. (The first four digits represent the year and the second two digits represent the month) For example, a tax period that end March 30, 2008 would be shown as 200803. For the establishment of Estate tax returns, the tax period is 000000. (L2-E3/P-ALL-L1/A-CIS/SSIVL)

Taxpayer Identification Number (TIN) - A more general name for the nine digit number used to identify a taxpayer. The TIN can be either an EIN or SSN. (L2-E1/P-ALL-L1). See Exhibit 4.4.1-23)

TC 150 Creation Date (TC150-CRTN-DT) - Renamed "Return Received Date" . (P1-L16)

TC 29X Indicator - IMF only. Effective 1/1/2005, IMF will set the TC 29X Indicator and will send this indicator to AIMS on opening and update records if there is a TC 29X posted at Master File that would cause the TC 300 with a TC 764 to unpost UPC 180 2. AMCLS will block the closure if a CREF 764 is input and the indicator is set unless a Priority Code (#9) of 1 or 8 is input. An error message: "TC-29X-IND PRESENT, CLOSURE BLOCKED TO PREVENT UPC 180 2" will be displayed. "29X" will be displayed on AMDIS within the MF-TC field on Screen-1/Line-7/Positions 23-53 if the indicator is present. (P1-L7)

TC 300 Indicator (TC-300-IND) - Indicates that an audit assessment has been successfully input through CC AMCLS. (P1-L9/SSIVL)

1 = IMF/BMF assessment
2 = IRAF assessment made against primary SSN
3 = IRAF assessment made against secondary SSN
4 = IRAF assessment made against both SSN's
5 = Indicates that the TC 300 indicator has been reset using CC AMAXU which causes the case to appear on the Non-Assessed Closures Listing.
6 = Indicates that the TC 300 indicator has been reset using CC AMSTUB (case returned to Examination from Appeals) or CC AMSTUR (a Status Code 90 case being reopened by Examination)

TC 424 Code - Identifies whether a case was opened on AIMS using AM424. (P1-L17/A-CIS)

0 = Record not established using CC AM424. Example: DIF and automatic openings
1 = AM424 with Source Code 60/EGC 1000/2000

TDA Status 26 - See Collectibility Indicator Code

Technique Code - See Examination Technique Code.

Technical Services Code - A three digit code required to be input when a case is updated to Status Code 21. The TS Code identifies which Technical Services Office (including TEFRA) has control of the case. See the Technical Services SC 21 worksheet for a complete listing of Technical Servics Codes.(P2-L4/A-CIS/SSIVL)

TEFRA Code/Indicator (TEFRA-CD) - The TEFRA code was created to identify on AIMS partnerships that are subject to TEFRA procedures. Once the revenue agent makes a determination as to whether the partnership is subject to TEFRA procedures, they must update ERCS/AIMS with a Y (yes) or N (no). If the agent surveys the return after assignment and is unable to make the determination the indicator should be set to a S (survey). If the MFT is 06 or 35, EGC is 1XXX or 2XXX, ERCS/AIMS will require the indicator be input if a case is opened in status codes 13-19, updated from a status code 12-19 to any other status code or a case in status code 12 is transferred to another PBC. (P2-L4/A-CIS/SSIVL)

TIN Change Record (F4) - Created when a data base is transferred to a different TIN. Remains on the data base for 60 days and cannot be deleted. (Summary Screen)

TIN-Type - See File Source.

Total Positive Income -Total Positive Income is a complicated calculation based on fields found on an individual tax returns and is used to create the Activity Codes on AIMS. Storing the TPI amount on AIMS started with records opened after 12/31/2006. For records on A-CIS that were created prior to 1/1/2007 the TPI amount was retrieved through MACS. (P2-L6/A-CIS).

Tracking Code (TRACK-CD) - A four digit code used to identify specific categories of returns. Effective 1/2/2009 - the tracking code cannot be corrected on a record with a status code greater than 79 if the case was closed in a prior fiscal year and the current date is after the end of the extended fiscal year. For a current listing of Tracking Codes see: http://sbse.web.irs.gov/AIMS/docs/TrackingCodes.xls . (L7-E24/P1-L14/A-CIS/SSIVL)

Transaction Code - Three digit code used to identify actions being taken to a taxpayers account. See Doc. 6209 for a complete list and definitions of these codes. See "Master File Transaction Code " for a list of MF TC's that are sent to the AIMS base.

Transfer Date - See AMSOC Transfer Date.

Transfer Terminal Code (TTC) - Set when a CC AMSOC, DC 30 is input. The AMDISA displays the prior PBC after the word "From" . (P1-L10/A-CIS/SSIVL).

If TTC is: then AMSOC DC 30 was: and displayed on AMDISA as:
0 Not input blank
1 Input at a SC terminal SC Transferred From
2 Input at an Area Office terminal DO Transferred From

Transferee/Transferor Assessment - See IRM 4.4.17, Jeopardy/Termination /Transferee/Transferor Assessment.

Unagreed Amount (UNAGREED-AMT) - The unagreed amount is the amount of tax adjusted by credits that is being appealed/petitioned. DO NOT include interest or penalties in the unagreed amount. This is a dollars only field - no not include cents in the amount entered in Item 18. See IRM 4.4.12 for more information. (P2-L6/A-CIS)
For taxable returns, this amount is from Item 18 on Form 5344, Examination Closing Record. If the tax that was stat noticed was actually assessed before the case was closed to Appeals, Item 18 must be $1 since the amount assessed will appear in the EXAM-CUM-ASSMNT-AMT or MAN-ASSMNT-AMT field. If Taxpayer appeals a disallowed claim, Item 18 must be $1-.

For non-taxable returns, the unagreed amount must be blank. The amount being appealed/petitioned must be entered in Item 34 on Form 5344.

Unified Credit Adjustment Amount (UNIFIED-CREDIT-ADJ-AMT) - This amount is from Item 422 of Form 5344. Valid for MFT 51 and MFT 54 if Disposal Code is 01. (P3-L10/A-CIS/SSIVL)

Unverified Assessment Listing - generated monthly for closed cases with a significant money amount successfully input through CC AMCLS but the TIF still contains a pending TC 300. See IRM 4.4.27 for more information.

Update Code (UPDT-CD) - This code reflects the last program or command code that modified the record. This code is moved to the Prior Update Code field when another update takes place. (P1-L17)

A = AM424 J = AMCLSF U = TSCLS
B = AMNON K = AMSOC V = AMCLSU
C = AMTIN M = AMLAB W = WTU17
D = AMAXU O = AMCLSO X = WTU18, 38, 58
E = AMSTU P = AMCLSI Y = AMS03
(AIMS Openings)
F = AMFRZ Q = AMS14
(Master File Update)
Z = AMS12
G = AMCLSP R = AMS21 + = AMS92
H = AMCLSE S = AMS41
(Monthly Report Extract)
- = AMS33
I = AMCLSA T = TSLOD @ = AMS22

Updating AIMS - See IRM 4.4.34.

Valid Segment - That part of the IMF containing SSN and name combinations that match the DM1 tape from Social Security Administration.

Verified Assessment Code (VER-ASSMT-CD) - Used to indicate whether the case has been reported on the Unverified Assessment List in a prior month. Part of TIF 80. (P1-L15)

0 = Not extracted for UAL
1 = CC AMAXU 901 input (Causes record to age even though there may be an unresolved pending transaction on the TIF).
2 = Extracted for UAL (Causes "repeat" indicator to appear on UAL).

X-REF DLN - See Cross Reference DLN

X-REF TIN - See Cross Reference TIN.

Whipsaw Indicator (WHIPSAW-IND) - An alpha indicator (K = key case, R = related case) input from Item 401 on Form 5344 which identifies records in which multiple taxpayers are assessed for the same liability. When the "K" is present the return and the Exam results are included in the AIMS tables. When the "R" is present, the return is counted on the AIMS tables but the Exam results are not. Table 16 is a listing of all cases that have a whipsaw indicator present. (P2-L9/A-CIS)

Aging of the AIMS Data Base

The aging of AIMS data bases occurs during the weekend of the monthly report extraction. The dates of the report extraction which are referred to as cycles, can be found in Document 6036, Examination Reporting System Codes Booklet, and Document 6209, IRS Processing Codes and Information.

Examined Closings

If the case is a: then, using the monthly report extraction cycle, it will age off of AIMS after the:
CIC Case 14th cycle
DC 10, 13 or 34 14th cycle
EGC 1XXX with Exam Results of + or - $50,000 14th cycle
EGC 2XXX with Exam Results of + or - $ 5,000 14th cycle
EGC 5XXX with Exam Results of + or - $ 1,000 14th cycle
All other examined closing that do not meet the criteria above. 3rd cycle

Non-examined Closings

If the disposal code is: then, using the monthly report extraction cycle, it will age off of AIMS after the:
20-29 2nd cycle
31-33, 35-99 3rd cycle
34 Use Examined Closures Chart

Non-Master File (NMF) and Dummy Record (-D) Closings

AIMS is the only source of identifying the DLN on NMF returns. The DLN is needed to retrieve a closed NMF file so AIMS stopped aging NMF records. Effective 1/1/2010, AIMS will age examined NMF and Dummy Record closings 10 years after the Status Code 90 date. Non-examined NMF and Dummy records will age using the same criteria of MF non-examined closings.

Skeletal Records/TC 424 Records/F1 Records

Type of Record Using the Opening-Creation Date, age the weekend after the:
TC 424 Rejects (except UPC 1830/3332 see below) Record appears on the TC 424 Reject Register
If TC 424 unposts with a UPC 1830 for IMF and 3332 for BMF 90th Day
Push Code 010 90th Day
No Push Code and no full base 90th Day
Retention Register Cases 90th Day if not brought back from retention
Any other Push Code and no full base 780th Day (26 months)

TIN Change Records

2 months from the time the TIN changes

Appeals Closings

All Appeals closures (except CC 33) will be removed from the AIMS data base after the third report extraction cycle. CC 33 cases will age after the first report extraction cycle. The cycle the case was closed can be found on Line 13 on the Appeals page of an AMDISA (APPL-EXTRACT-PRD).

Exceptions

No aging will occur if:
  the TC 3XX Indicator = 5
  verified assessment cd = 2 (See IRM 4.4.27, Reports, under the section, Resolving the Unverified Assessment Listing
  pending TC300 transactions
  case is on the Non-Assessed Closures list
  DQ unpostable not reinput
These modules must be resolved before the aging will occur.
If case remains on the AIMS data base after aging criteria is met, contact the Headquarter's AIMS Help Line.

The freeze is automatically released when the TC 520 is reversed. Freeze Code X can also be manually released using CC AMFRZR, however it should not be released without prior coordination with the Bankruptcy Coordinator. If Freeze Code X is present, a closure, partial or unpostable correction will be allowed if the case is a no change or a closure with an agreed or appealed disposal code of 03, 04, 07, 08, 09, or 11 in Item 13 of Form 5344.
Y Mirror Processing Used to identify a module where the -L freeze at Master File must be reversed while the mirror processing is taking place.
Z DC 29 The AIMS Freeze Code Z is automatically generated when a case is opened on AIMS (except MFT 01 or 52), if there is a prior audit in the Audit History section of Master File (IMFOLZ/BMFOLZ) with a DC 29 and the tax period in the first or second prior audit position is the year prior to the tax period being opened. A return with a Z freeze cannot be closed using DC 29. Any other disposal code is acceptable. This freeze cannot be released manually. The Z freeze will be automatically deleted from the AIMS base when the status code is updated to 12 through 40.
1 Protective Assessment Controlled by CCP - used to identify accounts where an assessment was made to protect the ASED. Contact CCP for input of freeze code if assessment was not done by CCP. See IRM 25.6.23.
2 CCP Used by CCP to prevent closing - generally requested by the group.

Combat Zone Procedures

IRM References
IRM 3.12.3 contains procedures related to combat zone condition codes (such as Master File Z freezes, K freezes, etc.)
IRM 4.10.8 contains guidance for Exam personnel and examples of compelling reasons to suspense examinations.
IRM 5.19.1.7.10 contains procedures for using the TC 500 with entry and exit dates.
IRM 25.6.16 contains procedures on statutes related to combat zone.
Case Identification - Freeze/Indicator TC Codes

A Master File indicator code (TC 500) was developed to identify combat zone personnel. A Master File freeze code "C" is set by a TC 150 with a Computer Condition Code of Z or TC 500 with a closing code input to any module in the account. A Combat Zone Indicator of a "1" will prevent AIMS openings, CF&S ordering offsets, suspend the ASED and CSED, restrict interest, failure to pay, delinquency and estimated tax penalties on all modules in the account.

Note:

If an S appears in the CSED field following the Closing Code (CC:52 CSED: S), this means that the spouse is in the Combat Zone. When inputting the reversal, you must enter an S in the CSED field so the reversal is applied to the spouse, not the primary taxpayer.

General Procedures
(1) Examinations are not to be conducted during the period of time a taxpayer is in the combat zone.
(2) Survey before assignment (Disposal Code 31) cases with no taxpayer contact.
(3) Survey after assignment (Disposal Code 32) cases involving taxpayer contact.
(4) Do not continue the examination if the taxpayer is in a Combat Zone unless a compelling reason exists to do so. For cases that require continuation because of a compelling reason, see (5) below.
(5) Compelling Reason Suspense Procedures - See IRM 4.10.8. A letter will be sent to the taxpayer informing them of the fact that examination action will be suspended until 180 days after their return from the combat zone. A request that the taxpayer notify the IRS upon their return from combat duty will be made. These cases should be held in the group and suspended using AIMS status code 14 (see also IRM 21.2.3.4.10.3 for procedures for generating combat zone status reports on AIMS). If case in not under AIMS control, use NMF AIMS until Combat Zone freeze is removed, then close the NMF control using DC 28 and establish the MF record.
(6) When the taxpayer returns from the Combat Zone or was never in the Combat Zone, see "Releasing the Combat Zone Freeze below"
(7) Combat Zone Indicator:
1 = on
2 = off
(8) Conflict Code
1 = Desert Storm, TC 500 with a Closing Code of 52 with entry date: Closing Code of 53 with exit date.
2 = Bosnia, TC 500 with a closing code of 54 with entry date; closing Code of 55 with exit date.
3 = Desert Storm and Bosnia, TC 500 with CC of 52 and 53.
4 = Enduring Freedom - TC 500 with a Closing Code of 56 with entry date; Closing Code of 57 with exit date.
5 = Enduring Freedom and Desert Storm - TC 500 with CC of 52 and 56.
6 = Enduring Freedom and Bosnia - TC 500 with CC 54 and 56.
7 = All 3 - TC 500 with CC 52, 54, 56.
Computer Condition Code K = Enduring Freedom
Computer Condition Code Z = Desert Storm
Releasing the Combat Zone Freeze
EXAMPLE: Since most cases we are seeing now have a Combat Zone of 1 (means it is set) with a Conflict Code of 4 (Enduring Freedom), we will use an Enduring Freedom case as an example.
Step #1: Pull an IMFOLE
Step #2: Look for the Combat Zone Indicator:
1 = on - go to Step #3
2 = off - go to Step #9
Step #3: Look for a TC 500 on IMFOLE with a CC of 56 and note the cycle date.
Step #4: Find the tax period where a return posted with this cycle date. Example: If the TC 500 has a cycle date of 200407, its probably a 200312 tax period.
Step #5: Pull up an IMFOLT for the 200312 tax period (if the 200312 return did not post 200407 keep looking at other modules for a TC 150 posting with this cycle). Once you find the tax period, go to Step #6.
Step #6: Look for a TC 500 posted to the 200312 module. If there is a TC 500 CC 56 posted to the module, it was not a return posting that caused the combat zone freeze. If there is no TC 500 posted go to Step #7. If there is a TC 500 posted go to Step #9.
Step #7: Look for a TC 160, TC 170 and TC 270 all for a zero amounts with the same DLN as the return. Look for a CCC K using IMFOLR. This indicates that the taxpayer wrote COMBAT ZONE on his/her return; which can be either a paper return or ELF. Seeing both of these things tells you that this is the module that caused the Combat Zone freeze and that the TP wrote Combat Zone on the return.
Step #8: In order to reverse the Combat Zone freeze, you must first post a TC 500 CC 56 to the 200312 module. If the taxpayer was in a Combat Zone you should input the exact date of entry. Note: The entry date must fall within the actual tax period - use the tax period that contains the date of entry. If the taxpayer was never in a Combat Zone, use the current date as the entry date.
Step #9: Once the TC 500 CC 56 posts, the Combat Zone freeze can be "turned off" .
If the Taxpayer was never in the combat zone, input a TC 502, this will reverse the -C freeze. ONLY USE 502 IF THE TAXPAYER WAS NEVER IN A COMBAT ZONE. Taxpayers in a Combat Zone ARE ENTITLED TO SPECIAL INTEREST AND PENALTIES COMPUTATIONS SO NEVER REVERSE THE FREEZE JUST SO THE CASE CAN BE OPENED.
If the taxpayer was in a Combat Zone, input a TC 500, CC 57 with the date the taxpayer returned from the Combat Zone. An entry and exit date should be obtained from the taxpayer. These are very important as these dates affect interest and penalties. Once the release date is obtained, input a TC 500 with a CC of 57. The transaction date represents the exit date. When the TC 500 with a CC of 57 posts, the -C freeze will remain at Master File. The Combat Zone Code will change to a 2, 180 days after the exit date. Do not input the TC 424 until the Combat Zone Code changes to a 2 or it will unpost.

DIF Reason Codes

The codes are determined by Master File using blocking series, asset values, etc.
Specials are caused by Audit Codes being entered by Code and Edit on the returns when they are filed.
When a DIF order is input, the computer identifies the returns being requested using the following codes:
     
Codes for Form 1040:
  R = No Audit Codes Present
  S = Audit Codes are Present
  T = NRP Return (Previously called TCMP)
Codes for Form 1041 or 1065:
  A = Automatic (1041 or 1065)
  B = Non-Automatic (1041 or 1065)
  C = Reserved
  D = Form 1065 DIF Scored Return Identified as a Special
  E = Reserved
  F = Reserved
Code for Form 1066:
  A = Non-Automatic
Codes for Form 1120:
  A = 1120F (Automatic)
  B = 1120L (Non-Special)
  C = 1120PC (Non-Special)
  D = 1120S (Automatic High Assets)
  E = 1120/1120A (Special)
  G = 1120 (Personal Holding Company Low Assets)
  H = 1120 (Automatic High Asset)
  I = 1120/1120A (Inactive Low Assets)
  L = 1120H (Homeowners Associations)
  M = 1120/1120A (Consol, Final, & Short Init. Per. (DIF)
  N = 1120L (Special)
  O = 1120PC (Special)
  P = 1120S (Special)
  Q = 1120F (Non-Automatic)
  R = 1120S (DIF)
  S = 1120FSC (Automatic)
  T = 1120SF
  U = 1120REIT
  V = 1120RIC
  W = 1120ND

Exhibit 4.4.1-11  (05-19-2009)
Disposal Codes

Examined Disposal Codes
01 No Change With Adjustments - Applies to no-change examined returns (even if a 30-day letter was issued) if there is an adjustment to the tax base data such as income or deduction items but no change in tax liability or refundable credits; or tax changes fell below the tolerance level in LEM IV. An audit report must accompany the case file. Note: An audit report is not required for most cases closed below the tax tolerance in the Campus TEFRA Function (CTF). An exception will be when the tax changes impact a prior or subsequent tax year (NOL, PAL, etc.), or other adjustment years are above the tax tolerance. Item 41 is required if MFT = 30. The following are examples of no-change with adjustments examinations:
  a. Delinquent returns secured by the examiner, accepted as filed and forwarded to the campus for processing. This includes delinquent return pickups that result in a zero tax liability. If the TC 424 posted prior to the posting of the delinquent return, enter the balance due or refund amount, excluding penalties in Item 414. If an SFR has been processed the amounts from the secured return must be input through AIMS therefore DC 01 does not apply.
  b. Claims disallowed in full. (Agreed or not agreed)
  c. Income tax examination when taxpayers are issued an examination report Form 4549 and Letter 1156 (see IRM 4.10)
  d. Flow through entities where no changes are made to the entities reported income, loss, deductions or credits reflected on the return or the owner(s) K-1 and (1) a delinquent return secured by examination, or (2) a balance sheet item is adjusted, or (3) a related return is adjusted as a result of the flow through examination (i.e.- adjustments to basis, at risk, or passive activity rules, taxable loan repayments or distributions, or adjustments to include the amount reported to the owners K-1).
  e. Estate or gift tax cases when offsetting adjustments result in no change in tax liability. This includes gift tax cases when Letter 942 (C) is issued to taxpayers (see IRM 4.10).
  f. Excise, trusts and estates, or employment tax cases when offsetting adjustments to tax base data and/or credits result in no change in tax liability.
  g Disqualified 1120 DISC(obsolete) / IC-DISC election.
  h Non-TEFRA (nontaxable) Flow through Entities. No Change with Adjustments - should be utilized when no changes are made to the entity's ordinary income or loss or separately stated items reflected on the return or Schedule K-1 and an owners return is adjusted as a result of the flow through examination. The would include:
adjustments to basis, at-risk, or passive activity rules:
taxable loan repayments;
adjusting the owners return to match the K-1 flow through amount(s).
02 No Change applies to examinations which do not necessitate the issuance of a report (other than the no-change report subject to area director's approval). This disposal code would also apply to changes only affecting the balance sheet, including constructive dividend issues, and any other related return pick ups where there were no tax liability adjustments to this return. Item 41 is required if MFT = 30. Block 405-408 of Form 5344 should be completed as appropriate.
a. Taxable returns - there were no adjustments or no changes in tax liability for this return to: Tax, penalties, or refundable credits. This disposal code would also apply to changes only affecting the balance sheet, including constructive dividend issues, and any other related return pick ups where there were no tax liability adjustments to this return. Item 41 is required if MFT = 30. Block 405 & 408 of Form 5344 should be completed as appropriate.
b. Flow through entities - no exam changes are made to the entities reported income, loss, deductions or credits reflected on the return or Schedule(s) K-1. (See DC 01 where adjustments are made to a related return.) Only applies to TEFRA returns closed within 45 calendar days (including weekends and holidays) from the date the NBAP is issued to the TMP.
c. Non-TEFRA (nontaxable) Flow through Entities should be utilized when the examination results in no changes to the entity or any owner. This would also be appropriate if you make adjustments to one of the owners returns as a result of compliance checks which are not related to the entity examination.
d Not valid with an amount claimed on the base.
03 Agreed—Applies only to returns if an agreement is received prior to the issuance of a 30-day or 60-day letter. EGC's 5XXX will not use DC 03 for agreements as their first contact with the TP is the 30-day letter.
Also applies to claims allowed in full and agreed claims partially allowed.
Tax Compliance Officers: ALL agreed income tax cases closing from office examination will use Disposal Code 03 regardless of whether a Letter 915, Letter to Transmit Examination Report has been issued.
Non-TEFRA (nontaxable) Flow through Entities: Applies to an agreed case if an agreement is obtained from all owners. If all signatures are received from the owners, you can close the case indicating on the entity report that agreement has been obtained from the owners.
04 Agreed - Applies only to returns if an agreement is received after the issuance of a 30-day or 60-day letter. Valid for partial assessment.
Non-TEFRA (nontaxable) Flow Through Entities
  Applies to an agreed case if an agreement is obtained from all owners. If all signatures are received from the owners, you can close the case indicating on the entity report that agreement has been obtained from the owners.
TEFRA
  Used for 1998 and subsequent TEFRA agreed cases (with or without penalties).
07 Appealed - Returns closed to Appeals before issuance of a 90-day letter, FPAA or FSAA.
08 Other (08 is included in the Agreed part of the AIMS tables). NOTE: Disposal Code 08 is used on the Form 5344 generated by RGS on cases that are being closed out of the group as unagreed for the issuance of a stat notice. Technical Services requests that the groups use DC 08 for cases forwarded to Technical Services for the issuance of a stat notice. Technical Services will update the disposal to the correct code upon final closure.
  Taxable Income Tax Returns
    unagreed claims partially allowed
    Form 906 agreement
    partial assessment of employee share of FICA
    any other manner of closing after issuance of a 30-day or 60-day letter.
    TEFRA: Used for 1997 and prior TEFRA agreed cases (with or without penalties). Also used for AARs and stipulated decisions.
 

Note:

It is no longer necessary to use DC 08 on SFR closures. Use applicable disposal code. If an agreed disposal code is used, AIMS will not send the agreement date to Master File therefore the interest and penalties will be computed correctly.
  Non-Income Tax Returns (MFT 01, 03, 10, etc.)
    Use when the taxpayer did not sign a report or request an Appeals conference.
  Non-Taxable Income Tax Returns (Forms 1041, 1065 or 1120S)
    Use when the taxpayer did not sign a report or request an Appeals conference.

A Push Code 049 will bypass the CI unpostable check. The return may not be closed as an examined closing or surveyed claim until the freeze is reversed. The return may, however, be closed as non-examined or protested to Appeals before the 91X freeze is reversed. Effective 1/1/2005, this Push Code can be used even though there is no TC 150 posted.
121 Pre-filing Notification (BMF only) This code is used for BMF accounts only, by the Tax Shelter Pre-filing Notification Program. This code freezes refunds and generates subsequent year returns to Examination.

Exhibit 4.4.1-15  (05-19-2009)
Reference Returns

Requesting Reference Returns
(1) The examiner must enter a brief reason for the request in the Reason For Request Box on Form 5345, or on Form 5354 in Item 23.
(2) Generally, a case should not remain in Source Code 45 for more than 30 days from the date the return is received in the group. The information needed from the return should be secured as soon as possible, and the return closed off of AIMS using the non-examined Disposal Code 45. Management approval must be obtained before Source Code 45 returns can be examined. If it is determined that the return is to be examined, the source code must be updated to the appropriate source code. Source Code 45 returns cannot be transferred or closed using an examined disposal code.
(3) Exception: Cases under jurisdiction of the Office of the Chief Counsel or the Department of Justice. Unless the subsequent period(s) involve issues that make an immediate examination compelling, the returns should be placed into Fraud Suspense. The status code should be updated to 32 and the source code will remain 45.
Request to Examine
(1) The examiner will request approval to examine the return using Form 5349, with a copy of original Form 5345 or 5354. The examiner will indicate the reason for examining the return by entering a new appropriate source code on Form 5349. The manager will indicate permission to initiate the examination by initialing and entering the date on the Approved By/Date line of Form 5345 or 5354 in Item 25 and Form 5349.
(2) Form 5349 will be forwarded for processing and the copy of Form 5345 or 5354 returned to the examiner to attach to the return as a permanent record.
Closing Reference Returns
(1) A photocopy of the approved request must be attached to the return as a permanent record.
Examined: SC 45 returns cannot be closed as examined - update to applicable source code.
Non-examined use:
  Disposal Code 45 to close reference returns that have not been started or examined. Use Disposal Code 45 if there is an original return or electronic print.
  *Disposal Code 28, to close Non-Master File AIMS.
  *Disposal Code 29 if the return was not received.
  *Use of these disposal codes must be approved by the AIMS Coordinator-AIMS/ERCS Analyst.

Retention Register Reinstatement Procedures

Modules are removed from the Master File and added to the Retention Register when certain conditions are met. See Retention Register for more information. Attempting to requisition a return on AIMS that has been moved to retention will delay getting a full AIMS base. To reduce the delay, the account must brought back to active status before the requisition is input. Before requisitioning a return on AIMS/ERCS:

  • See if the MFT and Tax Period are displayed on CC IMFOLI/BMFOLI without an R to the left of the MFT. If it is, the account is not on retention and you can requisition the return on AIMS/ERCS.

  • See if the MFT and Tax Period are displayed on CC IMFOLI/BMFOLI with an R to the left of the MFT. If it is, input CC IMFOLB/BMFOLB to bring the account back to active status. A message stating that the account will be brought back within 1 or 2 minutes will appear (actually it's 1 or 2 seconds). If this message does not appear it will be the next Monday before the account will be brought back. Always check to ensure the account is active before you requisition the return.

  • See if the MFT and Tax Period are displayed on CC IMFOLV/BMFOLV. If the MFT and Tax Period are displayed and the REMOVED cycle is:
    after 2001, input CC IMFOLB/BMFOLB to bring the account back to active status. When account is active, requisition the return on AIMS.
    prior to 2002, the account cannot be brought back to active status systemically. Use the following instructions which are also found in IRM 3.17.243, Credit and Account Transfers.

    1. Obtain a Retention Register transcript of the module to be reinstated.

    2. Review CC ENMOD/INOLE to determine the name line year for the taxpayer. The name line year appears directly to the left of the first name line.

    3. Compare the Retention Register transcript with the information on CC ENMOD/INOLE.

    4. If the name line year is subsequent to the year being reinstated, you must establish the name line for the year being reinstated (Use CC ENREQ, see IRM 2.4.9.

    5. If the MFR is 08, reestablish the filing requirement before reactivating the account. Care should be taken to delete the filing requirements once the adjustment has been completed if the taxpayer is no longer required to file a return.

    6. If more than one tax period is being reinstated and the name lines are the same, input the name line on IDRS for the oldest year.

    7. If more than one tax period is to be reinstated but the name lines are not the same, input a name line on IDRS for each year being reinstated.

    8. Prepare a Form 5248 to request the transfer-in of the deleted module on retention.

    9. Forward the Form 5248 and the retention register transcript to the Accounting function. Accounting will return a copy of the Transfer Request document indicating the cycle the module will be reinstated. Based on this information, cycle your transaction for processing. The AIMS AM424 request will automatically recycle. See Retention Register Indicator for more information on this process.

Taxpayer Identification Number

An asterisk (*) appears after the SSN on invalid numbers. If there is an asterisk (*) after the SSN and there is personal contact with the taxpayer, the examiner must ask the taxpayer if an inquiry has been received from the Service concerning the validity of the SSN.

  1. If the taxpayer has furnished the information requested by the Service, the examiner need not pursue the matter further.

  2. If the taxpayer has not furnished the information requested concerning the SSN, the examiner should secure a completed Form 4149 (Information to Correct Invalid Social Security Number) . The completed Form 4149 will be left in the case file.

An "N" after the EIN or SSN indicates Non-Master File.

A "D" after the number indicates a temporary number is being used. Examples of this are: waiting for taxpayer to secure a valid EIN; to establish a key case on PCS so that Schedule "C, Schedule F, etc., investors in a common promotion can be linked; or to control multiple Forms 706A on AIMS. The input format for a temporary number is XXXXXXXXX-D. Records that have a -D in the TIN cannot be closed to Appeals.

  1. CC AMTIN7 can be used to secure a temporary TIN.

  2. A temporary SSN can be secured to control a return if one is received without a SSN.

    1. Prepare Form 5354, Examination Request Non-Master File following instructions for Item 6 given in the Openings Section.

    2. When the permanent SSN is received as the result of the examiners having submitted Form 4149, request a new assembly on Form 5345, Examination Request Master File.

    3. Close the Non-Master File control using disposal code 28.

    4. Process the Master File account in the normal manner securing an EIN if the Taxpayer Refuses to File an SS4

A permanent EIN can be secured for a taxpayer if a return is received without a EIN.

  1. Contact the Entity Control Section at your Campus to secure a permanent number.

  2. Control the return on Non-Master File until the permanent number is received.

  3. After a permanent TIN is secured, close the base with the dummy TIN off of AIMS using CC AMSOC, DC 28.
