IRS Transaction Code Lookup

Type the three-digit code from an IRS account transcript and see what it means: a plain-English note for the codes you see most, and the IRS’s own description from Document 6209 for every code.

Transaction code or keyword TC Look up

An R after a code on a transcript (like 846R) means the transaction was reversed. Search the code without it.

Source: IRS Document 6209, Section 8A, Transaction Codes (2023), the most recent edition the IRS has published. The IRS description is shown as written. The plain-English notes are Y10 Tax Tech’s reading of that text, written for practitioners reading individual (IMF) transcripts. Codes and their uses change, so check anything that matters against the current transcript and IRS guidance.
