Understanding Internal Revenue Service Transcript Codes.
Having trouble deciphering your confusing IRS transcript? IRS transcripts allow taxpayers to obtain a record of their tax filings. You must have an understanding of the codes listed on the transcript to understand your tax return.
A tax transcript is a line-by-line reprint of the original tax return filed with the IRS. An account transcript contains the original tax return document and any subsequent additions or modifications. The account transcripts offer important information including: date the return was filed, additional assessed taxes and any payments made. Tax account transcripts indicate whether the tax return was filed by a taxpayer or as a substitute return by the IRS. Substitute returns are filed if a taxpayer has income but fails to file a tax return. IRS Transcript Codes – How to read your IRS Transcript.
IRS Transcript Codes
AIMS Serial Number — A computer generated nine digit number assigned to each return as it is established on the AIMS system.
ATIN — Is assigned by the Austin Campus as a result of an accepted Form W-7A application. This is a 9 digit temporary number beginning with “9” and the fourth and fifth digits “93”
Automated Non-Master File (ANMF) – Accounts processed manually in the Accounting Branch.
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.
Calendar Year Filer— Taxpayer whose fiscal or filing year coincides with the calendar year ending in
December.
Case File — The examined return, related work papers, correspondence, etc.
Check Digit — A check digit consists of two alphabetic characters. These characters are determined by the computer applying a mathematical formula to the Social Security Number or Employer Identification
Number. Located above computer generated name line.
Claim—FORMAL — A request prepared by or for the taxpayer submitted on Form 1040X, 843, and 1120X to reduce liabilities previously assessed. It can also be an amended return. INFORMAL — A letter or other document, not on Form 843, but prepared and signed by the taxpayer, requesting changes to obtain correct and accurate reflection of his/her tax liability.
Collection Location Code (CLC) – The campus that will be responsible for the collection activities if needed.
Composite Mail Processing System (COMPS) – This system will allow both incoming and outgoing mail to be processed at an increased rate of speed. This system has features such as remittance detection and a tape drive so that we can interface with our mainframe systems to update taxpayers’ accounts.
Control Date Recap (CDR) – A summary of DLN control date of pre-journalized money amount listed on the corresponding tape of Master Control Records, Good/Error/Reject Block Proof Records, or Nullified Unpostables.
Control DLN — The DLN under which a return is filed. May be the TC 150 DLN or a refile if subsequent adjustment has been made.
Controlling DLN – This document locator number (DLN) controls the location of a return in the files. It can
be an original return DLN or a new DLN assigned to certain examination or collection adjustment documents
(also known as Refile DLN).
Control Record Listing (CRL) – A consolidated listing of all records processed on the SCCF on a given day. This contains five major sub-sections:
- 1. Master Control Record Listing 4. Renumbered
Transaction Listing
- 2. Adjustment Control Listing 5. Nullified Unpostable
Listing.
- 3. Good/Error/Reject Block Proof Listing
Customer Account Data Engine (CADE) — Modernized database that is incrementally replacing the
Individual Master File (IMF).
Cycle — the transaction was posted by the new system called CADE, the Cycle will be displayed as follows: 20050601 – This means it posted in the year 2005, the 6th cycle and posted on Monday
2005 = year
01-52 = cycle
01-07 = day of the week 01 = Monday, 02 = Tuesday, 03=Wednesday, etc.
Cycle — If the transaction was not posted by CADE, the Cycle will be displayed as
follows: 20050608 – This means it posted in the year 2005, the 6th cycle and the day will always be 08
2005=year
01-52 = cycle
08 = day of the week is always 08 if not posted by CADE.
Cycle Proof Listing (CPL) – A listing of all blocks in which all documents have been sent to master file or rejected. This listing is used to shelve and associate all returns and documents in the files area.
Daily Block Proof Summary (DBPS) – A computer printout created daily as a management tool to monitor receipts, inventories, and processed volumes.
Daily Transaction Register (DTR) – Consists of information regarding the posting of payments, time of filing, and address information.
Data – Facts. For example, in processing individual income tax returns, that group of facts peculiar to a particular taxpayer.
Data Base – A data base is an organized grouping of data to fit the information needs of multiple functions of an organization. The data base can be manipulated through an on-line realtime system. A data base is accessed by using a command code.
Data Communication Processing System (DCPS) – The DCPS is also referred to as the “front-end”
processor, the “Traffic Cop”, or the Sperry 90/40 front-end processor. “Traffic Cop” is a good nickname,
since the equipment directs your command code terminal entry to a file (data base) where you may research or make changes.

RPS for balancing purposes.
Designated Payment Code (DPC) — A payment designated by the taxpayer for a type of tax.
Discriminant Function (DIF) – At MCC, tax returns are given a computer-generated score called DIF (Discriminant Function) score, which identifies those returns with tax change potential. This is most often associated with the examination function.
Disk or Diskette – Storage media for computer data. Disk refers to an individual platter constructed of a metal alloy which contains tracks cut into the platter so that a magnetic head can read or write on it. Diskettes are mainly constructed of a vinyl or plastic covered with a cardboard jacket. It also contains tracks. In both cases, the surfaces are magnetically coated. Information is recorded on circular tracks. Disks rotate like a phonograph record.
Disk Drive – Refers to the physical hardware that holds a disk pack or diskette or cartridge. The disk itself may be physically or dynamically removable or non-removable depending on the design. The disk drive may take a floppy disk, removable disk pack, disk cartridge, or it may contain fixed hard disks.
Disk Packs – Refers to a series of platters connected by a central hub. As explained in disk drives, packs may be physically or dynamically removable. The disk pack is kept off-line in a plastic housing with a handle. The bottom of the housing is removed and the disk pack is inserted into the disk drive. Then the top of the housing is removed so the access arms can gain entrance between the platters. The housing protects the disk pack against dust and contamination. Disk packs must be handled very carefully and cannot be dropped.
Distributed Input System (DIS) – The Distributed Input System (DIS) is the on-line realtime system that replaced the Directed Data Entry System (DDES) located in the Data Conversion Branch. The primary purpose of the DIS is for the data entry of a wide variety of tax returns and other tax related forms or documents.

The EPMF consists of three distinct sub–modules. These sub–modules are:
(a) The Sponsor/Employer entity module. (b) The Plan Data module.
(c) Returns module.
When making entity changes to plan data module, they must be input with doc. code 64.
Encoder – The hardware equipment that writes the magnetic information character recognition (MICR) on the bottom of incoming checks. It also prints identifying information on the back.

It contains his/her name, address, Social Security or Employer Identification number, employment code if applicable, name control, location codes, filing requirement codes, tax period, and date of establishment. In the case of IMF it also includes filing status, spouse’s name and social security number. This can also be a dummy module.
ERISA Filing Acceptance System (EFAST) — EFAST is a system, built and operated by NCS Pearson in Lawrence, Kansas, under contract to the Department of Labor, to process Form 5500 series returns. EFAST replaced IRS pipeline processing of the 1999 plan year returns in July 2000 and all plan year returns in July
- 2001. EFAST-processed returns post to the EPMF each week and can be identified by DLN File Location
Codes 56, 62, 72, 84, 86, and 91. Effective January 2010, ERISA Filing Acceptance System II (EFAST2), an all-electronic system, that will receive and display Forms 5500 and 5500-SF Annual Returns/Reports. The Form 5500-SF (Short Form) can be used by small plans (generally fewer than 100 participants) that meet certain other conditions.All Plan Year 2009 and later Form 5500 and Form 5500-SF Annual Return/Reports, as well as late and amended Annual Return/Reports for Plan years before 2008, must be submitted electronically through EFAST 2. All filings that are received by the EFAST2 electronic filing system will be posted on the Department of Labor’s web site within 90 days of receipt to satisfy the Pension Protection Act requirement that the Department of Labor display certain information, including actuarial information (Schedule(s) MB or SB), contained in the plan’s annual report.
Error Resolution System (ERS) – An on-line real-time error correction system where information is virtually immediately corrected and updated on the SCCF.

Julian Date — The numeric day of the year that the return or document was numbered for processing. (For example: January 15 +MC 015). The sixth, seventh and eighth digits of the DLN represent the Julian Date. Note: If the DLN is IDRS generated, this date will be incremented by 400 so January 15 would be shown as
415.
Key Verification (KV) – The process of verifying original entry (OE) data on a terminal.
Labels — AIMS provides three types of labels: audit (status), file, and address labels. Audit labels are used on AIMS forms for requisitions, updates, closings and corrections.
