The page no longer explains how to file a request, what fees might apply, where to send it, or who to call about a request already submitted. Your right to request IRS records comes from federal law and hasn't changed, but finding out how to use that right just got harder — you'd now have to hunt for the guide, the regulations, and the Public Liaison number on your own.
“FOIA requestors who have questions on a submitted request or want to know the status of a request may contact the IRS FOIA Public Liaison line at [312-292-2929](tel:312-292-2929).”
What you can do — Save these before they're harder to find: the IRS FOIA Public Liaison line at 312-292-2929, and the IRS FOIA guide at irs.gov/privacy-disclosure/freedom-of-information-act-foia-guidelines, which has a sample request letter and fee details. Also note irs.gov/privacy-disclosure/routine-access-to-irs-records for records you may be able to get faster without a full FOIA request.
