Program Scope and Objectives

  1. Overview: This IRM section provides an overview of the NMFST Command Code.

  2. Purpose: This IRM contains procedural steps for use of the NMFST Command Code. Command Code NMFST will end up to 10 transactions to a tax module that has already been established on IDRS. Only adjustments, payments, credit transfers, and penalty and interest assessments are valid inputs. DAR transactions must be pended using CC FRM77 or FRM7A. NMFST may be input from Service Center terminals only

  3. Audience: These procedures apply to IRS employees who are responsible for the processing of NMFST records. These employees are located in the following areas: Large & Medium-Sized Business, Small Business/Self-Employed, Tax-Exempt & Government Entity’s, and Wage & Investment.

  4. Policy Owner: IT

  5. Program Owner: The Chief Information Officer (CIO) is responsible for overseeing all aspects of our systems that operate the nation’s tax infrastructure.

  6. Primary Stakeholders: Large & Medium-Sized Business, Small Business/Self-Employed, Tax-Exempt & Government Entity’s, and Wage & Investment

  7. Program Goals: This IRM provides the fundamental knowledge and procedural guidance for employees who work with NMFST cases. By following the processes and procedures provided by this IRM, employees will process NMFST cases in a manner that follows IRS policy and procedures while promoting the best interests of the Government

Background

  1. This IRM and the contained sections provide the user the necessary information on how to use the command code NMFST

2.4.14.1.2 (11-07-2023)

Authority

  1. NMFST was develop to process subsequent transactions on automatic non-master file (ANMF) accounts established on the TIF

2.4.14.1.4 (11-07-2023)

Program Reports

  1. Entity Record: Each individual taxpayer or business is assigned a unique identity that contains information about them such as SSN/EIN,name and address. Transaction Record: Tracks the subsequent transactions for a NMFTM entity record. Transaction records must contain at least one transaction code. One or more transaction records can be assigned to a Module.
