Transcripts of Master File Accounts

  1. Data from a filed tax or information return for an individual taxpayer, business, or organization can be retrieved from IDRS. Employees can request a "transcript" of the information which can then be used to compare and verify it to the taxpayer’s copy of a return or to confirm the status of the taxpayer’s account, etc. The following explains the process:

    1. Information from a return is entered into IDRS at the IRS Service Campus where the return is filed.

    2. The information is transferred to the Martinsburg Computing Center (MCC) at Martinsburg, West Virginia on magnetic tape where it is added to other taxpayer accounts forming the Master File.

    3. Research for tax data is extracted from the Master File through the IDRS.

  2. The Master File is a central file divided into the following segments:

    Individual Master File IMF Contains information about taxpayers who file individual income tax returns and related documents.
    Business Master File BMF Contains information about taxpayers filing business returns and documents related to that business.
    Employee Plans Master File EPMF Contains information on returns filed for trusts and pension/profit sharing plans established for employees by firms or organizations.
    Individual Retirement Account File IRAF Contains tax and entity information for taxpayers who have established an IRA.
  3. Each taxpayer account on the Master File has a name and address section (the "Entity Module" ) and for each type of tax and tax period related to the entity, a separate tax module is on the Master File. The Entity Module contains data that applies to all of the taxpayer’s tax returns. Some of the more significant items of information on the Entity Module include:

    1. Taxpayer’s Name Control (first four letters of the individual’s last name or the corporation name).

    2. Social Security Number (SSN) for an individual tax return or Employer Identification Number (EIN) for a business tax return. The SSN and the EIN are commonly referred to under one general name — the Taxpayer Identification Number (TIN).

    3. Current address and zip code.

    4. Taxpayer’s filing requirements (a listing of all tax returns the taxpayer is required to file).

    5. IMF accounts include filing status, spouse’s name and spouse's SSN.

    6. BMF accounts include the date of establishment on the BMF and the tax year ending date.

  4. A Tax Module is a record of tax data for a specific taxpayer covering only one tax period.

  5. In addition to the above files, there is also Non-Master File (NMF).

    1. NMF is used to control returns or entities that are not available from the Master File.

    2. NMF is used in EP to post closing agreement data.

    3. The NMF accounts are not posted at MCC, but are local in scope and maintained by Cincinnati Submission Processing Center for purposes of EP. See IRM, Non-Master File Transcript Requests.

  6. Data for Non-Master File assessments are located on the ANMF (Automated Non-Master File) system. See Document 6209 , Section 7 for Non-Master File transaction codes and other related information.

  7. See Document 6209, Section 8 for Master File transaction codes and other related information.  (06-19-2014)

    1. Limit requests to the specific data for which there is an official need.

    2. The instructions on the back of Form 6882 , IDRS/Master File Information Request, briefly explain the information available for each IDRS command code listed.

    3. A record of the request should be maintained.

Payer Master File and Information Returns Master File

  1. The Payer Master File (PMF) and Information Returns Master File (IRMF) can be used to satisfy the package audit requirements of Policy Statement P-4-4. The on-line queries will assist agents in checking compliance with information returns filing requirements.

  2. The PMF was developed to increase compliance in the filing of the Form 1099 information return series.

    1. The PMF is a master file listing of entities, businesses and individuals, who file Form 1099.

    2. The file also contains information for each payer on penalties proposed and assessed.

    3. If it is determined that the taxpayer filed delinquent returns, and there is a need to ascertain penalties previously asserted, request a BMF or IMF transcript.

  3. The command code PMFOLS will provide a summary of the information contained on Form 1096, Annual Summary and Transmittal of U.S. Information Returns, filed by the taxpayer. PMFOLS lists each type of 1099 filed, the number of each type of 1099 filed, and the total amount reflected on each type of Form 1099.

  4. The command code PMFOLD will provide detailed information of the Forms 1099 filed.

  5. The command code IRPTR provides details of various information reports issued to a recipient. Using the recipient’s SSN, 1099-R information can be accessed which includes payee name and address, payer name and address, distribution amount, and withholding. Information on W-2s and Schedule K-1s can also be accessed.  (06-19-2014)
