Updated October 19, 2026. Quick answer: A CP59 says the IRS has no record that you filed your prior year personal tax return. File the return immediately or explain why you do not need to file. If you believe the IRS made a mistake, complete and send Form 15103. If you filed within the last eight weeks you do not have to do anything yet.

|---|---|
| What it is | No record of your prior year personal return |

What the notice says
“We have no record that you filed your prior year personal tax return.”
The action is “File your personal tax return immediately or explain to us why you don’t need to file.”
If you disagree or already filed
“Complete and mail or fax us Form 15103, Form 1040 Return Delinquency” if you believe the IRS made a mistake; you can also upload it through your IRS online account. If you filed in the last eight weeks: “You don’t have to do anything if you filed your tax return within the last eight weeks.”
If it has been longer: “Check the name, Social Security Number (or Taxpayer Identification Number), and tax year on your notice. Make sure they match the name, number, and year on the return. Mail us a signed and dated copy of the tax return.”
Why filing matters
The IRS says “If you don’t file, you may lose your claim to a refund or certain credits because the Internal Revenue Code sets strict time limits to claim those items.”
If you received an IRS Identity Protection PIN, the IRS says you must include it on the return, and each spouse’s IP PIN on a joint return.
Filing an old return
The IRS says “We can accept tax returns from the last 2 years electronically”, but you must find an e-file provider that offers it. Territory residents who filed with a territory tax office are told to contact that office first. Related: CP515, the IRS reminder for the same problem.
Where this comes from
The IRS page read for this page is the one titled Understanding your CP59 notice on irs.gov, as served on 2026-10-19. Your own notice controls: the dates, amounts and phone or fax numbers on it are the ones to use, and the IRS can update its page after we read it.
For IRS notices in general, Tax Topic 651 says “You should allow at least 30 days for a reply from the IRS.” It also says “Keep a copy of all IRS correspondence for your tax records.”
Common mistakes
- Ignoring the notice because you think the IRS has your return. Check that the name, number and year match first.
- Waiting to file because you expect to owe. The IRS says refund and credit claims have strict time limits.
- Leaving out an IP PIN on the return when you were issued one.
- Trying to e-file a return older than the last 2 years. Those go on paper.
