IRS Transaction Codes Pocket Guide – Helpful if You Need it ! by Robert Horwitz

The IRS transaction codes are typically listed on an taxpayers transcript of account. The transaction guide identifies many of the most often used codes.

“This document is an abbreviated version of the Transaction Codes listed in Document 6209 for quick reference. The transaction codes consist of three digits. They are used to identify a transaction being processed and to maintain a history of actions posted to a taxpayer’s account on the Master File. Every transaction processed by the Automatic Data Processing (ADP) must contain a Transaction Code to maintain Accounting Controls of debit and credits, to cause the computer at MCC/TCC to post the transaction on the Master File, to permit compilation of reports, and to identify the transaction when a transcript is extracted from the Master File.

The abbreviations used under the heading “File” are as follows: Individual Master File (IMF) “I”, Business Master File (BMF) “B”, Employee Plan Master File (EPMF) “E”, Individual Retirement Account File (IRAF) “A “, Payer Master File (PMF) “P”. ”
