Program Scope and Objectives

  1. This IRM section provides the instructions for the Integrated Data Retrieval System (IDRS) command code AMSOC. AMSOC closes cases that are non-examined. It transfers cases from one primary business code to another. It generates TC421 (FC) & (F3) transaction for short closings and TC428 (FD) transaction for transfers. AMSOCA – Appeals, AMSOCP – EP.

  2. Purpose: This transmits revised IRM 2.8.5, Audit Information Management System (AIMS), AIMS Command Code AMSOC.

  3. Audience: The audience for this IRM section are users of the Audit Information Management System (AIMS).

  4. Policy Owner: Information Technology, Chief Information Officer.

  5. Program Owner: Information Technology, Applications Development, Compliance, Business Compliance Management System Branch AIMS Related Section.

  6. Primary Stakeholders: IDRS users from Appeals, LB&I, SB/SE, TE/GE and TS

  7. Program Goals: To provide explicit instructions for the use of command code AMSOC in closing cases.

2.8.5.1.1 (01-02-2024)

Background

  1. As a result of a study, it was concluded that Examination had a need for a new information management system. The study group recommended a terminal assisted Audit Information Management System (AIMS). A stand alone direct access terminal system was considered along with the enhancement of IDRS. Enhancement of IDRS was determined to be clearly the best choice for the Service.

  2. This new system satisfied Examination Division's current needs for accurate and timely inventory controls, better control of assessments and up-to-date management reports. The system traces examination results through final determination of tax liability including Appeals and Tax Court.

  3. After the successful implementation of AIMS for the Examination Division, control of returns in Appeals was added to AIMS. As of January 1, 1977 control of Exempt Organization returns was added and on October 1, 1977 control of Employee Plan returns was added.

2.8.5.1.2 (01-02-2024)

Authority

  1. During the summer of 1973, the Deputy Commissioner established a Task Force to identify ADP requirements of Compliance functions, and to make appropriate recommendations to satisfy their needs.

2.8.5.1.3 (01-02-2024)

Responsibility

  1. Headquarters AIMS Related Section is responsible for maintaining procedures related to AIMS programming.

2.8.5.1.4 (01-02-2024)

Program Management and Review

  1. Command Code AMSOC is managed by Work Requests which are submitted for changes and also by tickets which are submitted by users for corrections.

2.8.5.1.5 (01-02-2024)

Program Controls

  1. IRS implements access control measures that provide protection from unauthorized alteration, loss, unavailability, or disclosure of information.

  2. SACS controls all the IDRS user accesses and permissions.

When disposal code 30 is used, the case will be transferred to the Primary Business Code input on the screen.

  2. CC AMSOC has two modifiers. They are:

    1. "A" which is to be used for Appeals accounts; and

    2. "P" which is to be used for Employee Plan accounts.

  3. CC AMSOC may be input as batch processing or as a single input.

  4. The input documents for CC AMSOC are:

    1. Form 5351, Examination Non-Examined Closings;

    2. Form 5596, TE/GE Non-Examined Closings;

    3. Form 5546, Examination Return Charge-Out; for Masterfile or Non-masterfile;

Command Code AMSOC

a) Batching is done in groups of one to 100 documents for short closings. Line 1 of the input screen is to be used to input data which refers to the entire block.
b) Computer Action for Batch Input the computer will perform validity checks between items for input for line 1 and lines 2–23. Each line beginning with line 2 is to be considered an individual entry, a maximum entry input per page will be 22 documents, to include line 2 thru 23. Line 24 is reserved for operational messages.
c) In the following display the five closings may be entered on one page
This is an Image: 28759001.gif

Please click here for the text description of the image.

a. For NMF cases the "L" in position 7, line 1 indicates that the last closing in the block is on this page (in this case line 6)
  1. Where the tax period or disposal code is blank, it is assumed to be the same as the previous line. For instance, in the input display, lines 4 and 5 are tax period 197412 and line 4 would be assumed to have a disposal code 21.
  2. When an entire block (more than 22 closings) cannot be entered on one page the "Batch Position Indicator" "L" will not be entered in line 1 of that page and the terminal operator will input the entry code and proceed to the next page by depressing the "Enter" key and omitting the MFT and blocking series from line 1 of the next page. When the last entry for the batch has been entered on the screen, the terminal operator will then enter the literal "L" in the seventh position of line 1, input entry code and depress the "Enter" key.
  3. When the literal ‘R’ is entered in the first position of any batch line 3–23 the TIN, Disposal Code, and Name Control entered on the previous line is repeated for the current line if those fields are left blank. For example, if an ‘R’ is entered in position 1 and positions 21–24 (name control) is left blank the name control from the previous line will be issued. If position 21–24 is not left blank whatever value is entered will be used whether or not there is an ‘R’ in the first position of the line.
