Identity, refunds & unfiled returns

CP63 notice — don't let this one sit

The IRS is holding a refund from a year you DID file because it shows earlier returns you did NOT file. File the missing years, and the hold can release.

Don't sit on it

What this letter is

The IRS is holding a refund from a year you DID file because it shows earlier returns you did NOT file. File the missing years, and the hold can release.

Why you got it: Your account shows unfiled prior-year returns; IRS policy holds refunds until a taxpayer is current on filing.

What it is not

Not a seizure: the money isn't gone, it's gated. But the gate has a trap — if a missing year's refund-limitations clock (3 years) runs out while you stall, money can be lost by calendar, not by decision.

Your first move: List the missing years from the notice, prepare those returns (oldest first if refunds there are near their 3-year limit too), and file them.

Your deadline, counted

The clock on this letter: Respond by the date on the notice — and mind the 3-year refund clocks.

The notice sets its response date. Separately, refunds for any year are generally forfeited 3 years after that year's filing deadline (26 U.S.C. 6511) — the reason missing years get filed promptly, not eventually.

Your options, in the order most people should try them

1. File the missing years

Transcripts (wage & income) rebuild most of what you need if your records are gone.

2. Explain where filing wasn't required

In writing, year by year, with income figures.

Your rights on this letter

  • File the missing returns at any time to release the hold.
  • If a missing year shows you weren't required to file, say so in writing.

How to respond

File the returns as the notice directs; keep e-file acceptances / certified-mail receipts per year.

Scam check

Your held refund cannot be 'released for a fee' by anyone but the process above.

If you ignore it

The refund stays held; missing years drift toward substitute-for-return treatment; and any refund attached to an old year can expire by its 3-year date.
