What it does

EFIN Verification Act of 2026

This bill requires the Internal Revenue Service (IRS) or a specified validator (e.g., software provider or state agency) to validate that an electronic filing identification number (EFIN) is authorized and active before a federal tax return or other document may be electronically filed with the IRS. (As background, an EFIN is assigned by the IRS to an individual or entity who is authorized to file federal tax returns and other documents on behalf of other taxpayers.)

Specifically, the bill requires (1) the IRS to develop a program to validate the status of an EFIN in real time, and (2) EFINs to be validated prior to the initial use and at intervals determined by the IRS.
