H.R. 9498 — Taxpayer Advocate Participation Act
What it does
This bill amends the Internal Revenue Code to authorize the National Taxpayer Advocate—an independent official within the IRS who advocates for taxpayers' rights—to file amicus curiae (friend-of-the-court) briefs in federal tax cases. The Advocate may participate when an issue could broadly affect taxpayers' rights, and federal courts must grant such applications. This gives taxpayers an official voice in tax litigation beyond the parties directly involved.
