You open your tax software or a letter from the IRS and learn that a return has already been filed in your name. It is a bad moment. The useful part is that federal agencies publish pages for exactly this situation, and you can work from them one step at a time. This article is general education, not tax or legal advice.
What a fraudulent return can look like
Often the first sign is a rejection. You try to file, and the system says a return already exists under your Social Security number. Other people hear about it by mail, in a notice about a return or a refund they never asked for. The sources retrieved for this piece do not list every warning sign, so treat these as common examples and not a full checklist. The IRS identity theft guide for individuals is the main federal starting point, and it is worth reading first.
Read the agency pages before you act, and keep every notice you receive.
Start with the IRS
The IRS runs its own identity theft victim assistance, and it publishes a page explaining how that process works. It also has a page on when to file an Identity Theft Affidavit, which is the form a taxpayer uses to report a fraudulent return. The PDF link in our research is labeled f14039, which suggests it is that affidavit. We could not read the file, so confirm the form name and instructions on the IRS site itself.
The IRS also has an FAQ on reporting identity theft under its procedures. Our retrieved text did not capture the page bodies. That means we cannot tell you which form to file in which case, how to submit it, or what order to contact agencies in. The pages themselves answer those questions, so read them before you send anything.

Report it to the FTC too
The Federal Trade Commission handles identity theft reports from a consumer side. It has a consumer advice page called What To Know About Tax Identity Theft, and a general page on reporting identity theft. A 2018 FTC post also describes reporting tax identity theft through IdentityTheft.gov. That post is several years old, so check the current site for how reporting works now.
Our sources did not capture the body text of the IdentityTheft.gov steps. Go to the site directly, and keep a copy of whatever report or confirmation it gives you. A written record helps if you need to explain what happened later.
Questions the sources do not answer
Several practical questions came up that the retrieved pages do not settle. We will not guess at them.
- Whether you need a police report.
- What to do about your state tax agency.
- Whether to check or freeze your credit reports.
- How the IRS Identity Protection PIN works and how to request one.
- How long processing takes, and whether any help costs money.
- What happens to a refund already sent to the fraudulent filer, and how your own return is handled afterward.
For each of these, the IRS and FTC pages above are the place to look. If a page is unclear, a qualified tax professional can explain your own situation. Deadlines are also unconfirmed in our sources, so do not wait. Reading the pages the same day you find out costs you nothing.
Keep a simple paper trail
Write down the date you first noticed the problem. Save every letter from the IRS, with its notice number if it has one. Note the date of each report and each call. One folder, on paper or on your computer, is enough. It turns a confusing weeks-long process into something you can follow.
Fraud like this feels personal, but it is a known problem with published steps. Start with the IRS guide, report to the FTC, and use the official pages to fill in what this article cannot.
Please seek a professional. This article is general information, not financial, tax or insurance advice. Please seek a licensed financial, tax or insurance professional about your own situation.
