Someone Filed Taxes Using My Information. What Do I Do?
If an e-filed return is rejected because a return was already filed using your Social Security number—or you receive an IRS notice about a return you didn't file—treat it as possible tax-related identity theft.
1. Keep the rejection or notice
Save the exact rejection message or every page of the IRS notice. It helps identify what happened and what the IRS is asking you to do.
2. Follow IRS identity-theft instructions
Use IRS.gov or the contact information on an authentic IRS notice. Depending on the situation, Form 14039 or another verification process may be appropriate.
3. Protect future filings
An IRS Identity Protection PIN (IP PIN) is a six-digit number that helps prevent someone else from filing a federal return using your SSN or ITIN.
4. Don't email sensitive information
Do not send Social Security numbers, identity documents, or tax documents through ordinary email. Use a secure method when documents are required.
