Program Scope and Objectives

2.8.2.1 (12-02-2024) Program Scope and Objectives This IRM section provides the instructions for the Audit Information Management System (AIMS) command code AM424. AM424 is used to establish a Master file tax module on the AIMS Data base. AM424 generates a TC 424 (FA) record to Employee Plans Master File (EPMF), Individual Master File (IMF) and Business Master File (BMF) when a tax module is established on AIMS. AM424D will generate an AM424-DELETE-RECORD (F#) record to End of Day (EOD) processing if the AM424 that established the Masterfile Tax Module and the AM424D are done on the same day. AM424D generates a TC 421(F7) record to IMF, BMF and EPMF when AM424D is used to delete a Master File tax module from AIMS when the AM424 to establish the tax module is not done on the same day. AM424M will generate a TC 421(F7) record to IMF or BMF to indicate that examination activity has occurred on a tax module that has not been established on AIMS. Purpose: This transmits revised IRM 2.8.2, Audit Information Management System (AIMS), AIMS Command Code AM424. Audience: The audience for this IRM section are users of the Audit Information Management System (AIMS). Policy Owner: Information Technology, Chief Information Officer. Program Owner: Information Technology, Applications Development, Compliance, Business Compliance Management System Branch AIMS Related Section. Primary Stakeholders: IDRS users from Appeals, LB&I, SB/SE, TE/GE and TS Program Goals: To provide explicit instructions for the use of command code AM424 in entering and requesting data.

Background

2.8.2.1.1 (01-01-2024) Background 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. 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. 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.

Authority

2.8.2.1.2 (01-01-2024) Authority 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.

Master File Request — Command Code AM424

2.8.2.2 (01-01-2011) Master File Request — Command Code AM424 Tax Return records for AIMS may be automatically selected through "DIF (Discriminate Function)" and "Unallowable" programs, or may be requested from masterfile via an AIMS realtime terminal. Command Code AM424 is used to request records for AIMS from IMF (Individual Master File), BMF (Business Master File), or EPMF (Employee Plans Master File). NMF records are established with Command Code AMNON. TC424 is generated to the appropriate master-file, and an open AIMS record is established on AIMS under the specific TIN (Taxpayer Identification Number), File Source, MFT (Master File Tax Account Code), and Tax Period (also, Plan Number if the MFT is 74 or Plan Report Number if the MFT is 46, 76, 84, 85 or 86). The TC424 request is sent to master-file for a " full" Tax Return record. If or when a TC 150 posts to Master File, a "full" record is sent back to AIMS along with a Return Charge-Out document and labels to be generated if requested. Upon receipt of the full record, AIMS sends a TC420 back to Master File when it replaces the original 424. An exception to the above chain of events occurs when Source Code 60 (Information Report) and EGC 1000 or 2000 are input with a valid push code by CC AM424; in this case, there is no TC424 generated to master-file and no Return Charge-Out document or labels are generated. If CC AM424 is re-input for the same tax module with a different source or EGC, the TC424 will be generated at that time. Input documents for CC AM424 are: Form Number Title 5345-B Examination Request Non-ERCS Users 5345-D Examination Request-ERCS (Examination Returns Control System) Users 5346 Examination Information Report 5347 Examination Multiple Request Master File 5571 Appeals Request 5597 TE/GE IMF/BMF/EPMF Request 5666 TE/GE Referral/Information Report 8340 PCS TEFRA Establishment or Add 8341 PCS Establishment or Add

Command Code AM424

2.8.2.3 (01-01-2011) Command Code AM424 There are two types of error messages that can be generated as a result of the input of CC AM424. The first type results from mistakes made on the input of data or from the input of data that does not match data at the NAP (National Account Profile). The second type will occur when the data was entered correctly but the TIN, F/S (File Source), MFT and Tax Period (also, Plan Number if the MFT is 74 or 76 or Plan Report Number if the MFT is 46 or 76 or 84 or 85 or 86) entered match a Tax Module already on the AIMS data base. Mistakes made on the input of data: Individual entries are processed one at a time. When an error is encountered, the entire screen will be displayed back and instead of the literal "OK " in positions 79 and 80 of the error line, asterisks (**) will be displayed. Line entries which follow the first erroneous entry will not be processed and positions 79 and 80 on these lines will be left blank when displayed back. When the input screen has been displayed back, the terminal operator may correct the invalid line entry and re-transmit the screen. If the operator wants to drop an invalid entry, the operator overlays the two asterisks with "DR" and retransmits the screen (Unless it is the last entry, in which case no action is necessary). Entry lines transmitted with "OK" in positions 79 and 80 will be returned with "BY" (by-pass) in positions 77 and 78. Account already on AIMS. A TIN, F/S, MFT and Tax Period (also, Plan Number if the MFT is 74 or 76 or Plan Report Number if the MFT is 46 or 84 or 85 or 86) entered with CC AM424 (either a single entry or in a batch mode) can match an existing account on AIMS for the following reasons: 1) There is already a full AIMS Account on AIMS. 2) There is already a "424" Account on AIMS. 3) There is a change TIN account. If a TIN, F/S, MFT and Tax Period (also, Plan Number if the MFT is 74 or 76 or Plan Report Number if the MFT is 46 or 84 or 85 or 86) input on AM424 matches a full open account on AIMS, two asterisks will be displayed in pos. 79-80 of the line item and an error message will be displayed on line 24 depending on the type of match IRM 2.8.2.3. Command Code AM424 Error Messages. When errors are detected by asterisks, (**), in positions 79 and 80 any of the following messages for AM424, AM424A, or AM424D may appear on line 24, (where applicable, the operator should correct and retransmit).

The blank space in positions 79 and 80 of lines 5 and 6 indicates that these entries have not processed because of the asterisks referring to line 4 entry. b. Error Display No. 2 Title: Error display for Command Code AM424. Description: This represents a screen shot of an error message. Line one starts with AM424, source code 64, PBC 205, SBC 87700, EGC 1974, MFT 30, status code 06, aging reason code 49 and statue day BB.

Please click here for the text description of the image. The error display above is the second response to an erroneous entry. Because the asterisks were not cleared from line 4 Entry the first time the input screen was displayed back, the invalid entry was bypassed and the message "DR" after Line 4 entry was displayed. Also, lines 2 and 3 will be bypassed and show "BY" in positions 77-78. c. CC AM424 input with Source Code 60 1. A source Code of "60" input with EGC 1000/2000 does not follow the standard AM424 processing. It will: a. Produce standard 424 base on AIMS which will stay on AIMS for a period of 26 months unless replaced by an opening record b. Not generate a transaction record to master file, unless an 039 Push Code is entered. 2. If at a later date CC AM424 is input with other than Source Code 60 or EGC 1000 or 2000, and it matches a 424 base on AIMS with a Source Code 60 and EGC 1000 or 2000, then the CC AM424 input will process normally but a special " Information Report Indicator" will be generated for print on the Form 5546.
