Your legal right to request government records is unchanged — it comes from federal law. But the page stripped out the tools that made that right usable: the step-by-step guide with a sample letter and fee explanation, the faster "routine access" option, and the phone number for checking on a request. Someone landing on this page now has no clear next step. The links may still work if you have them saved, and this could be a temporary page reorganization rather than a deliberate cut.
“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 the IRS FOIA Public Liaison number (312-292-2929) and bookmark the IRS FOIA guide at irs.gov/privacy-disclosure/freedom-of-information-act-foia-guidelines before you need them, since they are no longer linked from the main FOIA page.
