Tax Identity Theft: What to Do If Someone Used Your SSN

Attempting to file your tax return only to have it rejected because someone else has already filed using your Social Security number (SSN) is an incredibly stressful experience.

When a criminal gets hold of your SSN, they may rush to file a fraudulent tax return early in the tax season to steal your refund. If you are experiencing tax identity theft, someone used your ssn to commit fraud, and you must act quickly to secure your records with the IRS, protect your legitimate refund, and recover your identity.

This guide provides a step-by-step recovery process, detailing how to officially report the theft, file your rightful tax return, and make sure your identity is protected going forward.

Quick Answer: What to Do Immediately

If someone filed a tax return using your SSN, take these three critical steps right away:

1. File your taxes on paper: You cannot e-file if a return has already been submit for your SSN. Print your completed tax return and mail it to the IRS.

2. Submit IRS Form 14039: Complete the official Identity Theft Affidavit (Form 14039) and attach it to your paper tax return, or submit it online.

3. Create your FTC Identity Theft Report: Go to IdentityTheft.gov to log the theft and generate your official recovery document.

How to Tell If Someone Used Your SSN for Tax Fraud

Many taxpayers do not know they are victims of tax identity theft until they attempt to interact with the IRS or review their financial files. Common warning signs include:

• A Rejected E-File: When you or your tax preparer try to submit your electronic return, you receive an error message stating that the IRS has already received a return with your SSN.

• IRS Notices: You receive an unexpected letter from the IRS (such as Letters 5071C, 4883C, or 5747C) asking you to verify your identity.

• Online Account Activity: You get an alert that an online IRS account has been created, accessed, or disabled without your knowledge.

• Unfamiliar IRS Records: You receive a transcript or notice about tax years or income you do not recognize.

• Unreported Income: The IRS sends a notice (such as a CP2000) claiming you failed to report wages from an employer you never worked for (employment-related identity theft).

Step-by-Step Recovery Plan

Recovering from tax-related identity theft requires dealing with both the IRS and broader financial protections. Work through these steps methodically.

1. File Your Legitimate Tax Return on Paper

Even though someone else filed a fraudulent return, you are still legally required to file your own.

• What to do: Prepare your federal tax return as you normally would. You must print it out, sign it, and file it by mail.

• Why it matters: Electronic filing systems will continue to reject your SSN until the fraud is fully resolved. Mailing a paper return ensures the IRS receives your legitimate tax data.

• Note: Mail your return to the address specified for your state on IRS.gov.

2. Complete IRS Form 14039 (Identity Theft Affidavit)

Form 14039 is the official document that alerts the IRS to the duplicate, fraudulent return and prompts them to begin an investigation.

• What to do: Download and complete IRS Form 14039. Mark the box indicating that you are a victim of tax-related identity theft because someone used your SSN.

• How to submit it: You can attach the completed, signed Form 14039 to the back of your paper tax return and mail them together. Alternatively, you can submit the affidavit online through ID.me or by mail/fax separately if you’ve already had to submit your paper return.

• Include proof: You must attach a photocopy of one valid government-issued ID (such as a driver’s license, U.S. passport, or state ID card).

3. File a Report at IdentityTheft.gov

This creates your official FTC Identity Theft Report, which you will need for broader identity recovery.

• What to do: Visit IdentityTheft.gov and answer the questions about how your SSN was misused.

• The benefit: This portal can electronically transmit your Form 14039 information to the IRS and provides you with a comprehensive recovery plan to secure your credit, utilities, and financial accounts.

4. Protect Your Future Filings with an IRS IP PIN

An Identity Protection Personal Identification Number (IP PIN) is the ultimate defense against tax-related identity theft.

• What to do: Once the IRS processes your case, they will automatically enroll you in the IP PIN program, or you can opt-in proactively.

• How it works: Each year, the IRS will assign you a unique six-digit PIN. The IRS will not accept any electronic or paper tax return filed under your SSN unless it includes this exact PIN.

5. Lock Your Credit Files

If a thief has enough information (your SSN, name, and date of birth) to file a fake tax return, they can also easily apply for loans or credit cards.

• What to do: Contact all three major bureaus (Equifax, Experian, TransUnion) and place a credit freeze on your reports.

• Why it matters: A freeze completely blocks lenders from pulling your credit files, stopping the thief from opening fraudulent financial accounts in your name.

What Not to Do

• Do not send original ID documents: The IRS only requires legible photocopies of your identification for verification. Never send your actual physical cards.

• Do not fall for phone or email scams: Scammers often pretend to be the IRS to steal your recovery information. The IRS will not contact you by email, text, or social media, nor will they threaten you with arrest over the phone. Always verify unexpected communications by calling official IRS hotlines.

• Do not expect a fast resolution: Be prepared for a wait. While the IRS has a 120-day goal to resolve identity theft, backlogs mean identity theft victim assistance cases frequently take close to two years (19 to 20 months) to fully resolve. Stay patient and keep meticulous records.

What to Expect Next: Timeline & Resolution

Once the IRS receives your paper return and Form 14039, their identity theft victim assistance division will begin a review:

• They will review the conflicting returns and attempt to identify the fraudulent file.

• Your legitimate refund will be frozen during this process. The IRS will only release your refund after they have verified your identity and corrected your account records.

• If you face severe financial hardship (such as being unable to pay rent, utilities, or medical bills) due to a delayed refund, you should contact the Taxpayer Advocate Service (TAS) at 1-877-777-4778 for assistance.

Frequently Asked Questions

Can I track the status of my identity theft case?

You can check the status of your tax refund using the “Where’s My Refund?” tool on IRS.gov or by calling the IRS specialized identity theft line at 1-800-908-4490. Keep in mind that status updates may be limited until the investigation is complete.

Will my state taxes be affected by SSN theft?

Yes. If someone has used your SSN to file a fraudulent federal return, they may have also filed a fake state tax return. You should contact your state’s Department of Revenue or taxation agency to report the identity theft and check for any unauthorized filings on the state level.

Does tax identity theft hurt my credit score?

No. Tax identity theft with the IRS does not affect your credit score. However, because the thief has your SSN, they could also attempt to open fraudulent financial accounts, which can damage your credit. Placing credit freezes is essential to prevent this.

Should I pay someone to resolve my tax identity theft?

No. Filing IRS Form 14039, submitting identity theft reports to the FTC, and securing an IP PIN are completely free. You do not need to pay a service or attorney to resolve standard tax identity theft cases.

Final Takeaway

Experiencing tax identity theft, especially when someone used your ssn to file a fraudulent return, can be incredibly stressful, but the IRS has structured procedures to resolve it. Start by filing your correct return on paper, submitting Form 14039, and securing your credit. Be prepared for a lengthy investigation, keep detailed records of all notices, and use an IP PIN going forward to ensure you never have to deal with tax identity theft again.
