IRS CP01A
Identity Protection PIN — Your IP PIN for Next Year
The IRS has assigned you a 6-digit Identity Protection PIN. You must use it on next year's return.
Deadline
Use the IP PIN when filing your next tax return — returns filed without it will be rejected
If you file without your IP PIN, your return will be rejected by the IRS. You will need to locate your PIN or request a new one before your return can be processed.
Important — act before this escalates.
What IRS CP01A Means
CP01A delivers your annual Identity Protection PIN (IP PIN) — a 6-digit number that must be entered on your tax return each year. The IP PIN is a security measure for taxpayers who have been victims of identity theft or who have enrolled in the IRS's IP PIN program.
The IP PIN proves to the IRS that the return was filed by you, not a fraudster using your Social Security number. Any return filed with your SSN that does not include the correct IP PIN is automatically rejected — including fraudulent returns filed by identity thieves.
IP PINs change every year. The IRS mails a new CP01A in January or early February each year with the current year's PIN. Keep this notice in a safe place — you will need the PIN when you file.
What the IRS Can Do If You Don't Respond
- Reject any tax return filed with your SSN that does not include the correct IP PIN
- Issue a new IP PIN each January via CP01A

Frequently Asked Questions About IRS CP01A
What happens if I file without my IP PIN?
Your e-filed return will be rejected immediately. Your paper return will be flagged and delayed while the IRS verifies your identity. You must locate your IP PIN or get a new one before your return can be processed.
How do I get my IP PIN if I lost CP01A?
You can retrieve your current IP PIN online at IRS.gov using the 'Get an IP PIN' tool. You will need to create or log into your IRS account with identity verification.
Can my spouse have a different IP PIN?
Yes. Each taxpayer has their own IP PIN based on their SSN. On a joint return, both spouses must include their respective IP PINs if both have been assigned one.
