Historical Background

  1. A pilot IDRS was implemented at Southwest Service Center in July 1969. Based on experience gained from that pilot system, a new, improved, and enlarged IDRS was implemented at the Southwest Service Center in 1972. By July 1973 the new system was implemented in all service centers and field offices.

  2. The capabilities of the initial system included entering adjustments, entity changes, etc., as well as entering collection information for storage and processing in the system and the automatic generation of notices, collection documents, and other outputs. Various subsystems have since been added to the IDRS system:

    • EACS (EP/EO Application Control System),

    • ERAS (EIN Research and Assignment System),

    • RMIS (Report Management Information System)

    • QRDB (Quality Review Data Base)

    • ICTR (Intelligence Case Control and Time Reporting System)

    • REF (Refund Information File).

  3. The Integrated Data Retrieval System is designed primarily to accomplish the following:

    1. Provide better, faster, more responsive, and more personal service to the taxpayer.

    2. Facilitate and speed the work of employees in Campuses and Area Offices by providing the most current information on tax accounts, and by furnishing the most up-to-date data processing tools available today.

  4. Integrated Data Retrieval Systems were furnished to all Regions and Service Centers, beginning in 1972 and completed in early 1973.

  5. Beginning in October 1982, the IDRS System was transferred to UNIVAC 1100/84 computer equipment. This transfer was completed in the third quarter of 1984.  (01-01-2007)
Resolving Procedural and Computer Systems Problems

  1. When discrepancies, problems, recommendations, etc. surface, submit the information to Headquarters by the appropriate method as indicated below.


    Inappropriate forms will be returned without consideration (example would be using Information Technology Asset Management System (ITAMS) to report IRM inconsistencies).

    1. Use Form 5391, Procedures/Systems Change Request, to report non-emergency changes to the IRM or computer programs. See IRM 3.31.125 , ADP Evaluation - Procedures/Systems Change Request, for complete information on the preparation and routing of that form.

    2. Use ITAMS to identify computer programming or operational problems that need immediate attention. If the problem being reported is on a particular account, include a TIF Edit with the background information.

    3. Use the employee suggestion program to submit ideas to improve processing, eliminate waste/duplicate efforts or to improve taxpayer relations. See IRM 6.451.1 , Employee Performance and Utilization / Awards and Recognition - Policies, Authorities, Categories, and Approvals, and Document 11773 , Employee Suggestion Program Brochure, for information.

    4. Use Form 9345 or Form 9345A, Editorial Change Request, to report printing or typographical errors and incorrect IRM reference.


      Since operational problems or defects are not being reported on the form, the requests will not be controlled upon receipt nor will they require a written response.  (01-01-2005)
IDRS Data Bases Overview

  1. IDRS data bases are maintained in several separate areas. It is not necessary to know in which area a particular element of data is located. However, for clarity, the TIF sections are described separately in this section.

  2. This section describes the following files:

    • Employee Profile Security File (EPSF)

    • Terminal Profile Security File (TPSF),

    • Unidentified Remittance File(URF)

    • Dishonored Check File(DCF)

    • Taxpayer Information File (TIF)

    • Edited Research Data File (ERDF).

  3. The description of these files is included to facilitate use of IDRS. The IRM section "IDRS RESEARCH TECHNIQUES" and various sections on Command Codes are integral parts of the description of IDRS, and are to be used with this section to furnish an understanding of IDRS.  (01-01-2005)
Unidentified Remittance (UR)

  1. This file contains unidentified remittances. It replaces the Form 3731 (Unidentified Remittance Voucher) files previously maintained by the UR function. It provides a rapid research tool, for payment tracing, which is available to all area offices serviced by a campus. It generates credit posting documents or on-line credit postings when payments are applied. The periodic updating of the file results in registers and listings to be used for control and balancing.

  2. Content—The UR contains a record of each remittance that is received and cannot be positively identified. Each record contains the UR control number, amount, received date, and all known identifying data. In addition, the UR contains a record of all questionably-applied ES credits. These records, which are for information only, are added to the file by Clearing and Deposit after the remittance is applied to the taxpayer account. These records are excluded from the reports generated for the control and balancing of the UR.

  3. Updating—Additions to the file are made daily, or as needed, through terminals located in the Clearing and Deposit and the Unidentified Remittance areas. Application of UR credits may be made from specified terminals throughout the area office and/or campus, by persons designated to make such applications.

  4. Research—The UR is sequenced in three separate files:

    • the name file — alphabetically by name control

    • the amount file — by money amount

    • the control number file — by UR control number.

    To obtain a screen display of a UR record use CC URINQ with any combination of three data elements — name, amount or UR control number. The use of only one element will result in a display of all records in the file containing that element. An inquiry addressed to the name file or control number file produces a display of the complete UR record(s). An inquiry addressed to the amount file results in a display containing only the name control and UR control number. A further inquiry is necessary to produce a display of the complete record.  (01-01-2007)
Tax Information File (TIF)

  1. The Taxpayer Information File (TIF) will provide tax account information for taxpayers selected for IDRS. See http://unisysdb.web.irs.gov/glossaries.htm for latest changes.

  2. The TIF is divided into three subgroups.

    • The ITIF will contain data from the Individual Master File (IMF) . ITIF is broken into 100 areas- (ITIF00-ITIF99)

    • The BTIF will contain data from the Business Master File (BMF), as well as Exempt Organization (EO) cases. BTIF is broken into 100 areas - (BTIF00-BTIF99).

    • The ZTIF will contain data from Employer Pension Master File (EPMF) and the Non-Master File (NMF). ZTIF has one area - ZTIF01  (01-01-2005)
