2.4.21. Command Codes CHK64 and CHK64R

(1) This IRM section provides the instructions for the use of CHK64.

(2) Purpose :This transmits revised IRM 2.4.23, IDRS Terminal Input, Command Code CHK64.

(3) Audience: IRS Tax Technicians and Account Management employees.

(4) Policy Owner: Chief Information Officer.

(5) Program Owner: Customer Service.

(6) Primary Stakeholders: Wage & Investment (W&I).

(7) Program Goals: This system manages data extracted from Corporate Account Data Stores (BMF, IMF, EPMF) allowing IRS employees to take specific actions on taxpayer account issues and track status of an account .

(1) This section provides instructions that will release undelivered refund checks from the Individual Master File (IMF) and Business Master File (BMF) through an on-line process. Designated service centers and remote field offices will enter the command code "CHK64R" which is used to invoke the format for command code "CHK64". After the data for CC CHK64 has been inputted on to the database, it will create the reissue entity update (TC 018), close the control base, and generate Notice 564 (T/P notice of reissue action).

(1) Only on-line actions are inputted onto the IMF and BMF database. All EO/BMF accounts must be processed using CC RFUND. The CC EOCHG is used for any name line changes and the CC ENCHG is used for address changes.

(2) In all cases, for input to be accepted, the specific tax module containing an "S" (TC–740) freeze must be on the Taxpayers Information File (TIF). Dummy and Memo modules are not accept.

(3) CHK64R will determine from the TIN and File Source which IMF or BMF screen format will be displayed.

(4) A complete address must be entered on all on-line inputs. When there is no street address, "LOCAL" must be input in the street address field.

(5) A sequence of two command codes is required to allow input to be accepted:

1. Enter CC TXMOD to verify tax module's existence on the TIF.

2. Enter CC CHK64R to request the format for CHK64.

(6) When a CHK64 display is requested through CC CHK64R, name and address data will be displayed from the name and address section of the IDRS Taxpayer Information File if available. This data is overlaid if the name and address is not current because the taxpayer has a new name and/or address change. All changes made will be subject to validation by the main CHK64 processing. This change will be posted with the release of the "S" freeze.

(7) For tax accounts having more than one module that contains an "S" (TC–740) freeze, only one CHK64 need be input. It may be desirable to research via CC ENMOD to determine if CHK64 has already been input. You may wish to record history items using CC ACTON on the other modules involved.

(8) Case Control

1. No other employee can input CHK64 data when the control base status is S, A, or M. However, a case controlled to another employee but now in status B or C does not prohibit CHK64 input.

2. An additional control base is not established when the last control base of that module has the terminal operator's employee number as the assignee number and it was updated to status C today. CHK64 input case control information would be ignored by the computer.

3. A control base is generated automatically when the input terminal operator has no control base established for the module. The control base number may be entered via the screen. "C#" will be inserted if no alternative is input. Category "1664", status "C", and activity code "REISSUECHK " will always be inserted.

4. If the input terminal operator has an open control base established for the module, activity code "REISSUECHK" will be generated.

5. If TXMOD displays an "E" in position 38 or SUMRY displays an "E" in position 20; the entity module contains an open control base which may be related to your case. Contact the controlling employee before taking action.

(9) When all action is completed and CHK64 is released, assemble work papers and mark with date, employee number, and sequence number, Forward folders for association with Form 5147 (IDRS Transaction Record) and for filing. See "IDRS Transaction input" in the GENERAL IDRS TRANSACTION INPUT section of IRM 2.9.1.15.

(10) Unless specific instructions on entity changes are outlined in this section, instructions in IRM 2.4.9 for INCHG and BNCHG are applicable.

(1) Valid Responses:

1. "REQUEST COMPLETED" displayed on line 24

2. "TC018 PENDED/NO C BASE UPDATE/x/ "

(2) "X" is explained below, "dsii" is the file being accessed, "nn" is the SARA status code. "Dsii nn" will appear only when x = 1 or 2. A TC018 has been generated to the MF and the TIF but the control base has not been created or updated. Use TXMOD to verify whether or not control base has been updated. Use ACTON to create or update control base if applicable. DO NOT REINPUT CHK64.

(3) The value of "X":

(4) Terminal Error Responses:

(1) CC CHK64R — use this command code to request the format for CHK64. TXMOD must precede this request and the module must be present on the TIF and contain an "S" freeze.

(2) Record Element Description

(3) Terminal Responses

1. Error responses display in inverse video on line 13. CHK64R and CHK64 messages are listed together in the error response paragraph of this section.

2. Valid response is a display of the format for CHK64. The TIN, file source, and name control taken from TXMOD are generated on line 1 in positions 7–18 and 20–23. The MFT, PLAN-RPT-NUM, and TAX period from TXMOD are generated on line 1 in positions 25–26 , 28–30, and 32–37.

(1) IMF:

(2) BMF:

(3) Lines 6, 7, 8 and 9 (NAME LINES) are a protected field, any changes to the name lines will have to be done through BNCHG. (NAME LINES are only protected on BMF accounts)

(4) Record Element Description — BMF/IMF Elements in line 1 position 39 and line 2 through 9 are to be overlaid with the correct information.
