Key: what the circles and colors mean
Each circle is a bill. The ring fills as it moves through Congress:
Under the number: the Yea · Nay count of its final (or latest) recorded vote. On a member's page, the small badge is how that member voted: Y Yea / Aye, N Nay / No, P Present, – Not voting.
Gold and violet are only for Yea and Nay; they never mean a party. A member's party is the letter on their photo.
Not yet voted on. This bill is still a proposal: it hasn't reached a floor vote, and its text can change in committee or on the floor before any vote.

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.
