Tax identity theft: when someone files a return in your name to steal your refund
You go to file your taxes and the return is rejected — because one was already filed using your Social Security number. Tax identity theft is quiet, seasonal, and recoverable if you act. Here is how to spot it, prevent it, and fix it.
Most identity theft announces itself with a strange charge or a new account. Tax identity theft is quieter. You may have no idea anything is wrong until the one time a year you sit down to file — and your return bounces back, because someone already filed one using your Social Security number and walked off with the refund.
What it is
The IRS puts it plainly: tax-related identity theft “occurs when someone uses a stolen Social Security number to file a tax return claiming a fraudulent refund.” The thief does not need much — your name and SSN are often enough — and they move early in the filing season to get a return in before you do.
How to spot it
Because the crime happens inside the tax system, the warning signs come from the IRS, not from a scammer contacting you:
- Your e-filed return is rejected because a return with your SSN is already on file.
- You receive an IRS letter about a return, refund, or online account you never filed, requested, or created.
- A notice or transcript shows wages from an employer you have never worked for — a sign your SSN was used for work, too.
- You are billed for extra tax or collections on income you did not earn.
A note on imposters: real tax identity theft is discovered through official IRS notices. Scammers exploit the fear of it with fake “IRS” calls, emails, and texts — but the genuine IRS does not initiate contact by phone, email, or text to demand immediate payment. If a “notice” arrives that way, treat it as a separate government-imposter scam.
How to fix it
The good news, relative to scams where money is wired away forever: this is recoverable through a defined process. Start at IdentityTheft.gov, which the FTC and IRS jointly recommend. Reporting there creates an FTC Identity Theft Report, an IRS Identity Theft Affidavit (Form 14039), and a personal recovery plan in one place. Respond to any IRS notice using the contact details printed on the letter itself. The IRS says it will work your case — ultimately releasing any refund you are owed, removing the fraudulent return from your records, and marking your account with an identity-theft indicator to protect you going forward. You can reach the IRS identity-theft line at 800-908-4490.
How to prevent it
The single strongest move is to Lock the Front Door on your tax account: request an IRS Identity Protection (IP) PIN. It is a six-digit code that must appear on your tax return for the IRS to accept it — so even someone who has your SSN cannot file as you. Pair that with filing your real return as early as possible (beat the thief to it) and guarding your SSN.
If your SSN is already exposed from a breach, take the broader steps in what to do after a data breach and consider a free credit freeze. For more, see the defense library or test your eye on the 60-second quiz.
- Your e-filed return is rejected because a return with your Social Security number has already been filed.
- You get an IRS letter about a tax return, refund, or online account you did not file, request, or create.
- An IRS notice or tax transcript shows wages from an employer you have never worked for.
- You are told you owe additional tax, or collection action is taken, for a year you did not earn that income.
- You stop receiving expected IRS correspondence, suggesting your address was changed.
- Get an IRS Identity Protection (IP) PIN — a six-digit code that must be on your return for it to be accepted, which blocks anyone else from filing as you.
- File your real return as early as you can each year, so a thief cannot file first.
- Guard your Social Security number like a key: a tax thief mainly needs your SSN and name to file a fake return.
- If the IRS contacts you about suspected identity theft, respond using the number printed on the notice — and remember the IRS does not start contact by phone, email, or text demanding payment.
- If you are a victim, report at IdentityTheft.gov to generate your IRS Identity Theft Affidavit (Form 14039) and a recovery plan, then freeze your credit.
Tax identity theft is unusual among scams because the victim often does nothing wrong and notices nothing — until the one moment a year they try to file. The reassuring part is that, unlike a wired payment, this is recoverable: the IRS has a defined process to sort out the fraudulent return and release your refund. The unglamorous prevention — an IP PIN and filing early — is genuinely the strongest move, because it takes the thief’s whole play (file first using your SSN) off the table.

Frequently asked
How would I even know someone filed a tax return in my name?
Often the first sign is an e-file rejection saying a return with your SSN was already filed. The IRS may also send a letter about a return, refund, or account you did not recognize. As the FTC notes, "if the IRS says there's more than one tax return filed in your name, or they see income from an employer you don't work for", that points to tax identity theft.
What exactly is tax-related identity theft?
The IRS defines it simply: it "occurs when someone uses a stolen Social Security number to file a tax return claiming a fraudulent refund." The thief files early in the season, collects a refund in your name, and you discover it when your real return cannot go through.
What should I do first if it happens to me?
Report it at IdentityTheft.gov, which creates an FTC Identity Theft Report, an IRS Identity Theft Affidavit (Form 14039), and a personal recovery plan in one place. Respond to any IRS notice using the number printed on it, and follow your recovery plan — including freezing your credit. The IRS says it will release a refund you are owed, remove the fraudulent return from your records, and flag your account for protection.
How do I stop it from happening again?
Get an Identity Protection (IP) PIN from the IRS. It is a six-digit number that must appear on your tax return for it to be accepted, so a thief without it cannot file in your name. Filing early each year and protecting your SSN also help.
