What an IRS PIN is and why you need it

An IRS Personal Identification Number (PIN) is a five-digit code the IRS assigns to you to prevent identity theft on your tax return. The IRS uses it instead of your signature when you file electronically. If you have been a victim of identity theft or if the IRS suspects fraud on your account, they will require a PIN before they process your return.

You do not request a PIN in advance under normal circumstances. The IRS only issues one if your account has been flagged for identity theft protection or if you are filing after the IRS has already detected suspicious activity on your Social Security number. If you need a PIN because of identity theft, the IRS will mail it to you. If you need to retrieve one you were already issued, you have several options depending on your situation.

Key Takeaways

  • The IRS mails PINs to you by mail if identity theft protection is active on your account; you do not call to request one.
  • If you were issued a PIN and lost the notice, you can retrieve it through IRS.gov using your login credentials or by calling the IRS directly.
  • The IRS Identity Theft Hotline at 1-800-908-4490 handles PIN-related questions and can confirm whether a PIN is required for your return.
  • If you file without a required PIN, the IRS will reject your return and send you a notice explaining what to do next.
  • Paper filers do not need a PIN; the requirement applies only to electronic filing.

Retrieving a PIN you already received by mail

If the IRS mailed you a PIN notice and you have misplaced it, the fastest way to find your number is through your IRS online account. Go to IRS.gov, select "Sign in to your account," and log in using your Social Security number, date of birth, and filing status. Once logged in, look for a section labeled "Tax Records" or "Account Details." Your PIN should appear there if one has been issued to you.

If you do not have an online IRS account, you can create one during the login process. You will need your Social Security number, date of birth, filing status, and either a prior-year tax return or a credit card on file. The account creation takes a few minutes and gives you access to your PIN and other account information whenever you need it.

Keep the PIN in a safe place once you find it. You will need it every year if identity theft protection remains active on your account. Write it down separately from your tax documents, or store it in a password manager.

Calling the IRS to retrieve your PIN

If you cannot access your online account or prefer to speak with someone, call the IRS Identity Theft Hotline at 1-800-908-4490. This line is staffed during normal business hours, Monday through Friday, 7 a.m. to 7 p.m. your local time. Have your Social Security number, date of birth, and filing status ready when you call.

The wait time on this line can be long during tax season (January through April), so consider calling in the early morning or late afternoon to reach someone faster. When you reach an agent, they will verify your identity and read your PIN to you over the phone. Ask them to confirm the PIN is still active and whether you will need it for the current tax year.

What to do if you file without a required PIN

If you submit your return electronically without including a required PIN, the IRS will reject it. You will receive a notice in the mail explaining that a PIN is required and providing instructions on how to resubmit. Do not panic—this is a common situation and is easily corrected.

Once you receive the notice, retrieve your PIN using one of the methods above, then file an amended return or resubmit your original return with the PIN included. Your tax professional or software provider can help you add the PIN and refile. There is no penalty for resubmitting once you have the correct PIN.

Filing by paper if you do not have a PIN

If you cannot obtain your PIN in time to file electronically, you can file a paper return instead. The PIN requirement applies only to electronic filers. Print your completed tax form, sign it, and mail it to the IRS address for your state. Paper returns take longer to process—typically 4 to 6 weeks instead of 2 to 3 weeks for electronic returns—but they will be accepted without a PIN.

Include a note with your paper return explaining that you are filing without a PIN due to identity theft protection on your account. This alerts the IRS to expect the return and prevents it from being flagged as incomplete. Mail your return to the correct IRS address for your state, which you can find on IRS.gov or on the back of your tax form.

Understanding why the IRS issued you a PIN

The IRS assigns a PIN to your account for one of two reasons: you reported identity theft to the IRS, or the IRS detected suspicious activity on your Social Security number. In either case, the PIN is a security measure to may support that only you can file a return using your Social Security number.

If you did not report identity theft yourself, contact the IRS Identity Theft Hotline to understand what triggered the PIN. They can tell you whether fraudulent returns were filed in your name and what steps the IRS has already taken. You may also want to check your credit report through AnnualCreditReport.com and consider placing a fraud alert with the credit bureaus.

Frequently Asked Questions

Can someone else use my PIN to file a return?

No. The PIN is tied to your Social Security number and is meant to prevent exactly that. If someone files a return using your PIN without your permission, that is identity theft and should be reported to the IRS when ready at 1-800-908-4490.

What if I never received the PIN notice in the mail?

Check your online IRS account first—the PIN may have been issued even if the notice did not arrive. If it is not there, call the IRS Identity Theft Hotline. They can confirm whether a PIN was mailed and resend it if necessary. Mail can take 2 to 3 weeks, so allow time before calling.

Do I need a PIN every year?

Yes, if identity theft protection remains active on your account. The IRS will continue to require a PIN for electronic filing until they remove the protection. You can ask the IRS when they expect to lift it, though the timeline depends on the circumstances of the identity theft.

Can I file my return if I lose my PIN before the important date?

Yes. File a paper return instead. Paper returns do not require a PIN and will be accepted by the IRS. Mail it before the tax important date to avoid a late-filing penalty. Include a note explaining that you are filing by paper due to identity theft protection on your account.
