Identity, refunds & unfiled returns
The IRS can't finish processing your return without something: a missing form or schedule, a health-coverage form (Form 8962 for premium tax credits is the classic), a signature, or a document it names.
Handle it
The IRS can't finish processing your return without something: a missing form or schedule, a health-coverage form (Form 8962 for premium tax credits is the classic), a signature, or a document it names.
Why you got it: A required piece didn't arrive with the return, or a number needs a supporting form before the return can post.
Not an audit and not a bill — it's a processing hold. Your return is parked, not judged.
Your first move: Identify the exact item requested, get it (the letter names the form), and return it by the date in the letter with the letter's own response sheet on top.
The clock on this letter: Reply by the date printed in the letter.
The letter prints its reply date. Until you respond, the return doesn't process and any refund doesn't move.
Complete, signed where required, with their response sheet as page one.
Form 8962 + the 1095-A from your marketplace — the pair, not one without the other.
Address/fax printed in the letter; keep copies.
Letter 12C responses go by mail/fax or the IRS upload tool reached from IRS.gov — not via text-message links.
Processing stays stalled; eventually the return may be processed without the credit/item the form supported — or rejected back to you to paper-file.
Where this sits on the ladder: This letter stands on its own track — see the collection ladder for the enforcement road.
One payment. No subscription. Yours to keep — every notice, every letter, every script.
