This article explains what the CP01A notice is, how to use your IP PIN, and what to do if you misplace it.

The IRS has also improved the format by introducing a new self-mailer to protect your information. This article covers everything you need to know about the CP01A notice and how to handle your IP PIN.

What is the CP01A notice?
The CP01A notice is a letter the IRS sends each year to taxpayers who are assigned an Identity Protection PIN (IP PIN). This PIN helps protect against identity theft by ensuring only authorized individuals can file a tax return using your Social Security number. The notice provides a unique six-digit IP PIN for your federal tax return. Getting a CP01A notice does not mean you are a victim of identity theft. Instead, it’s a preventative step taken by the IRS, especially for those at higher risk, like past victims of identity theft.
Why does the IRS issue the CP01A notice?
The IRS issues CP01A notices as part of their efforts to fight identity theft, which has increased in recent years. The IP PIN program helps ensure that only the taxpayer can file tax returns under their Social Security number. This extra security layer is vital because identity thieves can misuse your SSN, file fake tax returns, and steal refunds. The CP01A notice ensures only you can file with your SSN.
Pro Tip
Always store your CP01A notice securely with your tax records to prevent losing your IP PIN. If misplaced, you can retrieve it online, but keeping the notice handy will save time.
Changes to the CP01A notice format
In 2024, the IRS updated the format of the CP01A notice to make it more secure. About 70% of taxpayers receiving the notice will see a new self-mailer design. This updated format better protects your IP PIN from being stolen through the mail. The IRS is also adding a survey to some of the notices to get feedback on the new design. Despite these changes, the way you use your IP PIN remains the same. The IRS will continue to send new PINs every year.
Security improvements with the new format
The new self-mailer format reduces the risk of your IP PIN being exposed during mailing. As identity theft methods become more advanced, the IRS has made this change to ensure your information remains secure. If you are part of the pilot group, you will receive your IP PIN in a tamper-proof mailer, giving you peace of mind.
What to do when you receive a CP01A notice
Once you get your CP01A notice, take immediate action to ensure your IP PIN is ready when you file your tax return. Follow these key steps:
- Read the notice carefully and understand how to use the IP PIN for your tax return.
- Keep the CP01A notice in a secure location with your other tax documents.
- Use the six-digit IP PIN when filing your tax return—whether filing online or on paper.
- Make sure your tax preparer has the correct IP PIN if you’re using one.
The IP PIN is only valid for the current tax year, and the IRS will send you a new CP01A notice every year with a new PIN. If you forget to include the IP PIN when filing, the IRS may reject your return, causing delays or complications.
How to use your IP PIN when filing your tax return
Using the IP PIN is simple. If you are filing electronically, enter the PIN when prompted. For paper returns, write the PIN in the “Identity Protection PIN” section. If your spouse or dependent also receives an IP PIN, they must enter it where required.
Pro Tip
If you use a tax preparer, ensure they receive your current IP PIN before filing your return. This avoids potential delays caused by missing or incorrect information.
What happens if you lose or misplace your CP01A notice
It’s essential to store your CP01A notice in a safe place, but sometimes mistakes happen. If you misplace your IP PIN, don’t worry—you can still recover it.
How to retrieve your IP PIN
If you lose your CP01A notice, visit the IRS website to retrieve your IP PIN. The IRS provides an online tool called “Get an IP PIN,” which allows you to recover or replace your PIN. To retrieve it, you will need to verify your identity by providing your Social Security number, date of birth, and other identifying information.
What if you can’t retrieve your IP PIN?
If you cannot recover your IP PIN online, you can contact the IRS directly. They will require additional identification to confirm your identity before providing a new PIN. In some cases, the IRS may give you the PIN over the phone or send a replacement by mail. To avoid delays, it’s best to secure your original CP01A notice right away.
Pro Tip
Enroll in the IRS IP PIN program even if you haven’t been a victim of identity theft. It’s an extra layer of protection that helps safeguard your tax return against fraud.
Common mistakes to avoid when using your IP PIN
Using your IP PIN correctly is crucial to ensure smooth tax filing. Mistakes with your IP PIN can cause delays or even lead to rejected tax returns. Here are some common errors and how to avoid them:
Entering the wrong IP PIN
One of the most common mistakes is entering the incorrect IP PIN on your tax return. This error can happen if you misplace your CP01A notice or confuse it with an older PIN. Always make sure to use the current year’s six-digit IP PIN, as the IRS issues a new one each year. If you’re unsure, check your IRS online account or use the “Get an IP PIN” tool to retrieve the correct number.
Forgetting to include the IP PIN
Forgetting to include your IP PIN on your tax return is another frequent mistake. The IRS requires this PIN to verify your identity. If it’s missing, your return may get rejected. Whether you are filing electronically or by paper, be sure to enter the IP PIN in the designated box.
Sharing your IP PIN with unauthorized people
Your IP PIN is a sensitive piece of information meant to protect your identity. Sharing it with anyone other than your authorized tax preparer could expose you to identity theft. Never share your IP PIN casually, and always ensure your tax preparer is trustworthy and authorized to file on your behalf.
Using the wrong year’s IP PIN
Each IP PIN is only valid for one tax year. Using an old IP PIN for the current year’s tax return will result in errors. The IRS sends a new CP01A notice every year with an updated IP PIN. If you haven’t received it, check your IRS account or contact the IRS directly.

Frequently asked questions
Why did I receive a CP01A notice?
You received a CP01A notice because the IRS assigned you an Identity Protection Personal Identification Number (IP PIN) to protect your tax account from identity theft. The IRS issues this PIN annually to taxpayers who are part of the IP PIN program.
What should I do if I don’t receive my CP01A notice?
If you are expecting a CP01A notice but don’t receive it, check your online IRS account to view your notice and PIN. You can also contact the IRS for assistance if the notice doesn’t arrive by mail.
Do I need to file a Form 14039, Identity Theft Affidavit, if I receive a CP01A notice?
No, you do not need to file a Form 14039 if you receive a CP01A notice unless you are experiencing an actual case of identity theft after receiving your IP PIN. The CP01A notice is a preventive measure, not an indication of active identity theft.
Can I opt-out of receiving an IP PIN?
Currently, once you are enrolled in the IP PIN program, you cannot opt out. The IRS automatically assigns the IP PIN to taxpayers at risk of identity theft, and the PIN must be used when filing your tax return.
Will the IP PIN work for state taxes?
No, the IRS IP PIN is only used for federal tax returns. Some states may issue their own PINs for state tax returns, but these are separate from the federal IP PIN.
