If someone filed a federal tax return using your Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN), follow the exact instructions on any IRS notice, complete the requested identity verification, and tell the IRS that you did not file that return. Do not automatically send Form 14039, and do not submit duplicate affidavits.
Do these things first
- Secure the IRS notice. Keep the entire letter, envelope and every page. Notices in the CP5071 series and Letter 5447C ask you to verify your identity and the tax return. If the return shown is not yours, state that during the notice-directed process.
- Use only the contact method printed on the notice. Follow its online, telephone, mail or document-upload instructions. If online verification is unavailable, use the alternative channel the notice provides.
- Do not file Form 14039 just because your e-file was rejected. First determine whether the IRS has already routed you through return verification. The IRS says a completed verification process generally removes the need for Form 14039 unless the agency specifically tells you to file it.
- Prepare your legitimate return. If you have not filed and electronic filing is blocked because a return is already on record, the IRS may direct you to file a paper return after identity verification.
- Protect future filings. An IRS Identity Protection PIN (IP PIN) is a six-digit annual code that helps stop another person from using your SSN or ITIN on a covered federal return.
- Address other misuse. Report stolen identity information through IdentityTheft.gov, consider notifying your state tax agency, and contact financial institutions if bank, card or other financial information was exposed.
Choose the IRS path that matches your situation
These are procedural routes, not competing services. The correct route depends on whether the IRS sent a notice, whether you filed the return in question, and whether your own return has already been submitted.

| Situation | Primary action | What not to do |
|---|---|---|
| You received a CP5071-series notice or Letter 5447C | Complete the identity-and-return verification using the notice instructions. Say that you did not file the identified return. | Do not bypass the notice by mailing a second affidavit unless the IRS directs you to. |
| You have no notice-directed verification and believe you are a tax-related identity-theft victim | Read the current Form 14039 instructions and follow the route they specify for your facts. | Do not assume every rejected e-file requires Form 14039. |
| Your legitimate return has not been filed and e-filing is blocked | After following the IRS identity process, file on paper if the IRS recommends or requires it. Use the address and submission method in the notice or current form instructions. | Do not abandon your own filing because a fraudulent return is already in the system. |
| You already filed Form 14039 for this incident | Keep the confirmation and follow any IRS correspondence about that case. | Do not send another Form 14039 for the same incident. |
Start with an authentic IRS notice
A notice means the IRS needs to establish whether the return belongs to you. A CP5071-series notice or Letter 5447C normally provides a verification route. CP5447 guidance likewise directs the recipient to verify identity and the return, then use the notice instructions if online verification fails.

Match the tax year, filing status and other return details to your circumstances.

Keep a copy of anything you send and a record of the date, method and confirmation number.

If the return is not yours
When the IRS verification asks whether you filed the return, answer that you did not file it. The notice-directed service is specifically designed to let a taxpayer reject a return filed by someone else. Complete every requested identity check; an incomplete response can leave the account unresolved.
If online verification fails
Do not create a duplicate case simply because the online channel did not work. Follow the notice’s telephone, mail or document-upload alternative. The IRS may request identity documents or other information through that channel. Send only what the instructions request and retain proof of delivery or submission.
When Form 14039 is appropriate—and when it is not
Form 14039, Identity Theft Affidavit, is conditional. IRS guidance says it is generally unnecessary when you complete a notice-directed return-verification process. Use the current form instructions when you have not received a notice that routes you through verification and your facts indicate tax-related identity theft.

It warns: “To avoid delays do not use this form if you have already filed a Form 14039 for this incident.” That warning means one incident should not generate repeated affidavits. A duplicate can slow case handling and make it harder to match your documents to the existing case.
Before sending the form
- Confirm that your problem is tax-related identity theft, not merely a rejected return caused by a data-entry error or a return that you forgot had been filed.
- Check whether an IRS notice already requires verification; if it does, use that process first.
- Read the February 2026 instructions for the correct filing method and destination.
- Copy the completed form and every attachment before sending.
File your own return if e-filing is blocked
A fraudulent return on record does not replace your legal obligation to file your genuine return. Once you complete the identity process, the IRS may recommend a paper filing if your electronic submission remains blocked. Follow the address, signature, attachment and delivery requirements in the notice or Form 14039 instructions that apply to you.
Use a complete copy of your legitimate return and retain evidence of mailing or delivery. Keep wage statements, income records, withholding information and schedules with your tax files. Do not alter figures merely to make an electronic system accept the return, and do not send multiple paper copies unless the IRS instructs you to do so.
What happens after verification
After the IRS establishes that you did not file the return, it says it will remove that return from its records. The agency may also place an identity-theft indicator on your account after the account issues are resolved. A paper return may be recommended when your own filing has not yet been accepted.

Use an IRS IP PIN for future protection
The IRS describes the IP PIN as “a 6-digit number assigned to eligible taxpayers to help prevent the misuse of their Social Security number (SSN) on fraudulent federal income tax returns.” The IRS FAQ carrying that wording was updated May 21, 2026.
An IP PIN is an IRS credential, not a commercial monitoring product. An eligible taxpayer who can verify identity may enroll. Confirmed victims of tax-related identity theft are enrolled in the program. A new PIN is generated each year, and you must enter the current PIN on covered federal returns whenever the filing process requires it.
How to handle your PIN
- Keep the annual number private; do not post it or send it in response to an unsolicited message.
- Give it only to a trusted preparer when necessary to complete a covered return.
- Make sure the correct year’s PIN is used; an old number will not substitute for the current one.
- Remember that an IP PIN protects federal tax-return filing. It does not by itself repair compromised bank accounts, credit files or state tax records.
Respond to identity theft beyond the IRS
Tax-return fraud can be one part of a broader identity compromise. Report the stolen SSN or ITIN information through IdentityTheft.gov and notify the IRS using the applicable process. Consider reporting the incident to your state tax agency because state filing rules and protective measures can differ from federal procedures.

If the person who used your identity also accessed money or financial data, contact the affected bank, card issuer, brokerage, payroll provider or other institution through its official channel. Ask what account-security steps apply, such as changing credentials or reviewing transactions. Keep these reports separate from your IRS case so each organization can track its own investigation.

Common mistakes and the safer alternative
| Mistake | Why it causes trouble | Safer alternative |
|---|---|---|
| Ignoring the notice because the return is not yours | The IRS still needs your response to determine who filed it. | Use the notice verification path and state that you did not file. |
| Mailing Form 14039 immediately after receiving a verification notice | It can create a duplicate case. | Complete the requested verification unless the IRS asks for the form. |
| Sending multiple affidavits for one incident | The February 2026 form warns this can cause delays. | Send one form only when current instructions indicate it is required. |
| Giving up after an e-file rejection | Your genuine return may still be due. | Complete identity verification and paper-file if the IRS recommends it. |
| Trusting an unsolicited caller who offers to “clear” the fraud | Scammers may seek your SSN, IP PIN or payment. | End the call and use the contact information printed on the IRS notice. |
| Assuming an IP PIN fixes every identity problem | It covers covered federal returns, not all financial or state accounts. | Use IdentityTheft.gov, notify the state agency and contact affected institutions as needed. |
When specialized help makes sense
The IRS lists 800-908-4490 for specialized assistance with identity-theft-related tax-account issues. Follow your notice’s contact instructions first; the notice route is the controlling process for that case.
Consider a qualified tax professional or enrolled agent experienced in IRS identity-theft resolution when the case involves several tax years, business and individual returns, a deceased taxpayer, disputed ownership of the return, or repeated correspondence you cannot interpret. Verify the person’s credentials, location, services and authorization before sharing tax records. A private adviser cannot replace the IRS verification or notice requirements.
Limits of this guidance
This article addresses U.S. federal individual income-tax returns filed with an SSN or ITIN. State procedures may differ. An IRS notice is a request to establish facts, not automatic proof that fraud occurred. The correct form, filing method and response deadline are determined by the exact notice and your circumstances. Neither a refund amount nor a universal resolution date can be promised.
Bottom line
Use the authentic IRS notice as your roadmap: verify your identity, reject any return you did not file, avoid duplicate Form 14039 submissions, file your legitimate return by the method the IRS directs, and obtain an annual IP PIN after the case is confirmed. Then report broader identity misuse to the appropriate government and financial institutions.
