Form 14039, the IRS Identity Theft Affidavit, is a document you submit online to report that someone has used your Social Security number to file a fraudulent tax return. It triggers the IRS's identity theft resolution process and helps restore your tax account.
The IRS launched the online version of Form 14039 in 2021 to reduce delays and improve access for victims. You can complete and submit it through the IRS Identity Theft Online Portal, which requires a U.S. taxpayer ID, a valid email, and a secure internet connection. The system verifies your identity using IRS records and prompts you to provide details about the fraud.
Once submitted, the IRS assigns a unique case number and begins reviewing your claim. Most cases take 16 to 24 weeks to resolve, though some may take longer depending on complexity. The IRS uses Form 14039 to flag fraudulent returns, reverse incorrect refunds, and reissue your correct tax transcript.
When you file Form 14039 online, you enter personal information such as your full name, SSN, date of birth, address, and contact details. The system cross-checks this against IRS databases to confirm your identity. If discrepancies exist, you may be asked to verify additional details or upload supporting documents.
After verification, you answer a series of questions about the identity theft incident. These include whether you received a notice from the IRS about a fraudulent return, the date the fraud occurred, and whether you've reported the crime to law enforcement. You must provide the name and address of the fraudulent filer if known.
The IRS uses your responses to determine if the case qualifies as identity theft under Internal Revenue Code ยง 6103(k)(2). If approved, the IRS places a "fraud alert" on your account and suspends further processing of any suspicious filings until the issue is resolved. This prevents additional harm while the investigation proceeds.
To start the process, you need:
You must also have a recent IRS transcript or account statement showing your filing history. Without this, the system may reject your application due to insufficient data. The IRS recommends downloading your IRS Tax Account Transcript before beginning the form.
If you're reporting a stolen SSN used by someone else, you must confirm that you did not file a return under that number. The IRS checks this against prior filings. If you previously filed a return using the same SSN, the system may flag it as a duplicate and require clarification.
Many people assume that submitting Form 14039 automatically reverses a fraudulent refund. That's not true. The IRS must first validate the claim and then manually reverse the payment. This process takes time and does not guarantee a full refund.
Another misconception is that Form 14039 replaces the need to contact the FTC. You must still file a report with the FTC Identity Theft Data Base. The FTC provides a confirmation number that you should include when submitting Form 14039. The IRS cross-references this number during review.
A lesser-known fact: the IRS does not send a physical copy of Form 14039 after submission. All communication happens via email or through your account dashboard. You'll receive automated updates, including case status changes and requests for additional documentation.
Form 14039 can be filed online or by mail. The online method is faster and more secure. Below is a comparison of both options:
| Feature | Online Submission | Mail Submission |
|---|---|---|
| Processing time | 16-24 weeks | 3-6 months |
| Confirmation receipt | Instant email | 10-14 days |
| Document uploads | Supported (PDF, JPG) | Required (must be scanned) |
| Case tracking | Real-time dashboard | Manual follow-up needed |
Online submission reduces errors and speeds up verification. Mail forms often delay processing because they require manual entry and scanning. The IRS reports that 78% of online submissions are processed within 20 weeks, compared to 45% of mailed forms.
In 2023, a California resident named Maria received an IRS notice stating she had filed a 2022 tax return with $12,400 in income and claimed a refund of $2,100. She hadn't filed any return. She checked her IRS transcript and confirmed no activity under her SSN.
Maria visited the IRS Identity Theft Online Portal and began Form 14039 online. She uploaded her 2022 W-2, a copy of her driver's license, and her FTC Identity Theft Report. The system verified her identity within 12 minutes and prompted her to describe the incident.
She entered the date of the fraudulent filing (January 15, 2023), identified the fake return as filed under her SSN, and confirmed she had not authorized anyone to file on her behalf. The portal generated a case number (IDT-2023-456789).
After submission, monitor your email and the IRS portal dashboard for updates. The IRS may request additional documents, such as bank statements showing no deposit from the fraudulent refund, or a police report if you reported the crime to law enforcement.
If you don't hear back within 30 days, call the IRS Identity Theft Hotline at 1-800-908-4490. Have your case number ready. The IRS advises calling only if you haven't received an update in 30 days, as high call volumes can delay response times.
Once your case is closed, the IRS sends a final letter confirming your identity is restored. You can then proceed with filing your actual tax return. If you need help preparing your return, use the IRS Free File program or consult a tax professional.
