IRS & TAXES

What is an IRS CP80 notice and what should I do?

SHORT ANSWER

A CP80 means the IRS has credited payments to your account for a tax year but hasn’t received your return for it. It often shows a credit or refund waiting behind a missing return. If you’re required to file, file that year’s return now; if you already filed, send a newly signed copy to the address on the notice.

A CP80 notice tells you the IRS has money — payments or credits — posted to your account for a specific tax year, but no return on file to go with it. That mismatch usually happens one of two ways: you had withholding or made payments but never filed that year’s return, or you did file and the return was lost, unsigned, or never processed. The notice matters because that credit doesn’t sit there forever: there’s generally a three-year window to claim a refund, and after it closes the money is gone. So a CP80 is often good news wrapped in a chore — there may be a refund waiting, but only once the return is on file. What you should do depends on which situation you’re in. If you were required to file and didn’t, prepare and file that year’s return right away and mail the signed original to the address printed at the top of the notice. If you’re sure you already filed, send a newly signed copy to that same address so the IRS can match it to the credit. If you want the credit moved to a different year or account instead, call the number on the notice.

What to do, in order

  1. Identify the exact tax year on the notice — the credit and the missing return both belong to that specific year.
  2. If you were required to file and haven’t, prepare that year’s return and mail the signed original to the address at the top of the notice.
  3. If you believe you already filed, send a newly signed copy of the return to the same address so it can be matched to the credit.
  4. Don’t wait: a refund tied to the credit generally must be claimed within about three years, or it’s forfeited.
  5. To move the credit to another tax period or account instead of filing, call the IRS at the number on the notice.

Common questions

Does a CP80 mean I’m in trouble?

Not usually. It means the IRS received payments or credits but no return for that year. Often there’s a refund waiting — you just have to file the missing return so the IRS can release it.

I already filed. Why did I get this?

The return may have been lost, unsigned, or never processed. The IRS asks you to send a newly signed copy to the address on the notice so it can be matched to the credit already on your account.

Is there a deadline?

Yes, effectively. A refund from an overpayment generally must be claimed within roughly three years of the return’s due date. If you wait past that window, the credit is typically lost even though it’s on your account.
