What an IRS PIN is and why you need one

An IRS PIN (Personal Identification Number) is a six-digit code the IRS assigns to you to prevent someone else from filing a tax return in your name. If you have been a victim of identity theft or if the IRS suspects fraudulent activity on your account, they may require you to use a PIN when you file. The PIN replaces your Social Security number as the identifier on your return.

You do not choose your own PIN — the IRS generates it and sends it to you by mail. Once you receive it, you enter it in a specific field on your tax return. If the IRS has assigned you a PIN and you file without it, your return will be rejected.

Key Takeaways

  • The IRS mails your PIN to your address on file, usually arriving in mid-May, and you cannot request it by phone or email.
  • If you do not receive your PIN by early June, contact the IRS using Form 14039 or call 1-800-908-4490 to report identity theft or verify your mailing address.
  • You can check whether the IRS has assigned you a PIN by logging into your IRS account at irs.gov using your Social Security number and password.
  • When you file your return, enter your PIN in the field labeled "Identity Protection PIN" on Form 1040 or your tax software's equivalent field.
  • If you lose or forget your PIN after receiving it, you can retrieve it from your IRS online account or request a replacement by mail.

Check your IRS online account first

Before contacting the IRS, log in to your account at irs.gov to see if your PIN is already there. Go to the homepage, select "Sign in to your account," and enter your Social Security number, date of birth, filing status, and the prior-year tax return amount. You will need to verify your identity using either a text message, email, or security questions.

Once you are logged in, look for a section labeled "Tax Records" or "Account Details." Your PIN will appear there if the IRS has assigned one to you. This is the fastest way to retrieve a PIN you have already received but forgotten. If no PIN appears in your account, it has not been issued yet or the IRS has not processed your request.

Wait for the PIN to arrive by mail

If the IRS has assigned you a PIN because of identity theft or suspected fraud, they will mail it to the address they have on file for you. The PIN typically arrives in mid-May, before the tax filing important date. The letter will come from the IRS and will clearly state your six-digit PIN.

The mailing address the IRS uses is the one from your most recent tax return. If you have moved since you last filed, update your address with the IRS before the PIN is sent. You can do this by calling 1-800-829-1040 or by mailing Form 8822 (Change of Address) to the IRS address for your state.

Report a missing PIN or verify your address

If you do not receive your PIN by early June and you know the IRS assigned one to you, contact the IRS directly. Call 1-800-908-4490 (the Identity Theft Hotline) and explain that you have not received your PIN. Have your Social Security number, date of birth, and current mailing address ready.

Alternatively, you can file Form 14039 (Identity Theft Affidavit) by mail if you believe your identity has been stolen or if you need to report that you did not receive your PIN. Mail the form to the IRS address for your state. Processing by mail takes longer than a phone call, but it creates a paper record of your report.

If you suspect your mailing address is incorrect in the IRS system, verify it during your phone call. The IRS representative can confirm the address they have on file and update it if needed. A corrected address will help may support future correspondence reaches you.

Retrieve a PIN you have already received

If you received your PIN in the mail but have lost the letter or forgotten the number, you have two options. The first is to log into your IRS online account at irs.gov (as described above) and look for your PIN in the Tax Records section. This is the quickest method and works if you can remember your login credentials.

The second option is to call the IRS at 1-800-908-4490 and request that they mail you a replacement PIN. You will need to verify your identity by providing your Social Security number, date of birth, and other information from your tax return. The replacement PIN will arrive by mail within two to three weeks.

Enter your PIN when you file your return

When you file your tax return, you will see a field on Form 1040 labeled "Identity Protection PIN" or similar wording depending on your tax software. Enter your six-digit PIN exactly as it appears on the letter the IRS sent you. Do not add dashes, spaces, or leading zeros.

If you are using tax preparation software, the PIN field is usually on the first page of the return or in a section about identity protection. If you are filing by paper, write the PIN in the box on Form 1040 next to the identity protection PIN label. If you have a PIN but leave this field blank, the IRS will reject your return.

If you file electronically and your return is rejected because of a missing or incorrect PIN, you will receive an error message. Correct the PIN and resubmit. If you file by paper and make a mistake, the IRS will contact you to request the correct PIN before processing your return.

What to do if you never receive a PIN notice

If the IRS assigned you a PIN but you never received the notice, do not panic. You have options. First, check your IRS online account to confirm whether a PIN was actually assigned. If your account shows no PIN, the IRS may not have issued one yet, or there may be a delay in processing.

If your account does show a PIN but you never received the letter, call 1-800-908-4490 to report the missing notice. The IRS can confirm your mailing address and mail a replacement. If you are filing soon and cannot wait for the replacement to arrive, ask the IRS representative whether you can file without the PIN this year and provide it in a follow-up letter. Policies vary, so the representative can tell you what applies to your situation.

Frequently Asked Questions

Can I choose my own PIN number?

No. The IRS generates your PIN randomly and mails it to you. You cannot request a specific number or create one yourself. The PIN is assigned by the IRS system and is unique to your tax account.

What if I file my return without entering my PIN?

If the IRS assigned you a PIN and you file without it, your return will be rejected. You will need to correct the return, add the PIN, and resubmit it. This delays processing and any refund you are owed.

How long does it take to receive a PIN in the mail?

The IRS typically mails PINs in mid-May, and they usually arrive within one to two weeks. If you do not receive yours by early June, contact the IRS to verify your mailing address or request a replacement.

Can I get my PIN by phone or email instead of waiting for the mail?

No. The IRS only sends PINs by mail to the address on file. You cannot receive your PIN by phone, email, or any other method. Be cautious of anyone claiming they can provide your PIN through other channels — that is a sign of a scam.

What if my PIN arrives after I have already filed my return?

If you filed before receiving your PIN and the IRS assigned you one, your return may be rejected. Contact the IRS at 1-800-908-4490 to explain the situation. They can tell you whether you need to amend your return or if they will process it with the PIN added.
