Why you received this notice

A federal income tax return, Form 1040 series, was filed under your Social Security number (SSN) or individual taxpayer identification number (ITIN).

We sent you this notice because we need you to verify your identity and the return:

  • If you didn’t file a return: Verify with us. You may be the victim of identity theft.
  • If you did file a return: Verify so we can continue processing the return.

What you need to do next

Verify your identity and return.

If you can’t verify online, you can verify by phone, by mail or with the Document Upload Tool. Follow the instructions in your notice.

How to protect your identity

To prevent someone from filing a return with your Social Security number (SSN) or individual taxpayer identification number (ITIN), get an identity protection (IP) PIN.

If you verify your return, you don’t need to complete Form 14039, Identity Theft Affidavit, unless we tell you.

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.

Not advice. Not a filing. Verify with a licensed professional. Rules change by year and facts.
