Start with the IRS notice or e-file rejection in front of you. A CP5071-series notice or Letter 5447C sends you to the IRS Return Verification Service; an e-file rejection because another return used your Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN) generally means you still need to file your legitimate return, usually on paper, and report the problem. A confirmed identity-theft case may require Form 14039, but not every identity-verification notice does. The correct path depends on what the IRS actually sent and what happened to your return.
First, identify which IRS process applies
Tax identity theft is not one single IRS workflow. The trigger—an identity-verification letter, a rejected e-filed return, a notice about a return you did not file, or an already confirmed theft—determines what you submit and how you check progress. Use the notice number and its instructions before taking any other step. Make sure the communication is genuine, keep a copy, and use only the phone number, web address, or mailing directions printed in the notice.

| What happened | Primary IRS action | What not to assume |
|---|---|---|
| CP5071-series notice or Letter 5447C asking you to verify a return | Use the IRS Return Verification Service with the notice and the relevant Form 1040-series return available. | The notice does not by itself prove that you committed identity theft or that Form 14039 is required. |
| Your legitimate e-filed return was rejected because a return already used your SSN or ITIN | Report the suspected theft to the IRS, file your own return on paper when e-filing is unavailable, and use Form 14039 in the manner IRS guidance and your case require. | Do not abandon your own filing because another return appeared first. |
| You know or strongly suspect someone filed a federal return in your name | Follow the IRS reporting guidance and the instructions for your situation; file your legitimate return and pay any tax due. | Do not send a duplicate affidavit simply because you have not received a status update. |
| You received CP01A, the annual IP PIN notice | Use the six-digit IP PIN on applicable returns during that calendar year. | CP01A alone does not mean you must file Form 14039. |
What should I do immediately?
1. Preserve the evidence
- Save the complete IRS notice, including every page and any tear-off section.
- Keep a copy of the return you submitted, Form 14039 if you use it, delivery confirmation, and every IRS letter.
- Write down dates, the office or service used, confirmation numbers, and the names or identifying information of representatives you speak with.
- Do not send sensitive information in response to an unsolicited email or text. Verify the communication through the IRS instructions or an official IRS channel.
2. File your real return
The IRS advises taxpayers to file their own return and pay any tax due even when a fraudulent return may already be on the account. If an electronic filing is rejected because the SSN or ITIN has already been used, print and mail the paper return as directed for your situation. Attach or send Form 14039 only when the applicable IRS instructions call for it; the form is not a universal substitute for return verification.
3. Respond once, then wait for the next IRS request
Answer IRS requests for documents or information promptly. After you have supplied what the applicable process requires, repeated status calls and duplicate submissions can slow the case rather than accelerate it. The IRS states: “Do not submit duplicate Forms 14039, nor contact the IRS about the status of your identity theft claim, this will cause delays if duplicate forms are received.” Use the IRS processing-status information for posted form processing times and wait for the IRS to contact you unless your notice tells you to take another action.

CP5071 or Letter 5447C: how to verify a return
Use the Return Verification Service only when the notice directs you
The Return Verification Service is designed for a CP5071-series notice or Letter 5447C. It is not a general identity-theft portal for every tax problem. Have the notice and the relevant Form 1040-series return available, then follow the service’s prompts exactly.
If you filed the return
Complete the verification requested by the service. The IRS uses that response to decide whether the return can continue through processing. Keep the confirmation or other record the service provides.
If you did not file the return shown
The service can be used to tell the IRS that someone may have attempted to file using your information. That response is different from confirming a return you prepared. IRS guidance says people who verify through this service do not need to file Form 14039 unless the IRS instructs them to do so.

Someone filed taxes in my name—what should I do?
If another person used your SSN or ITIN to file a federal individual return, report the suspected tax identity theft to the IRS and continue with your legitimate filing. The IRS reporting guidance addresses this situation directly: What can I do if I think someone has filed a tax return using my Social Security number?
When e-filing is blocked
- Save the e-file rejection message and its rejection code or explanation.
- Prepare your complete, accurate federal return.
- Mail the return on paper when the IRS victim-assistance guidance says e-filing is unavailable because of the prior filing.
- Complete Form 14039 if the instructions for your incident require it. Place it where the current form instructions direct—IRS victim-assistance guidance describes attaching it to the back of a paper return or sending the paper return separately, depending on the circumstances.
- Use a trackable delivery method when mailing and retain the receipt and a full copy.
When the IRS has already contacted you
Use the notice’s procedure first. A notice may direct you to online verification, a particular phone line, or a document response. Do not replace that procedure with a generic affidavit unless the IRS says to do so. If the notice directs you to call, use the number printed on the letter; IRS reporting guidance also identifies specialized assistance at 800-908-4490.
What happens after referral
For a confirmed tax-related identity-theft case, the IRS assigns the matter to its Identity Theft Victim Assistance organization for research and resolution. When the case is resolved, the IRS says it will contact the taxpayer. Until then, respond to information requests promptly and avoid sending duplicate Forms 14039 or repeatedly asking for the claim’s status.

Do I need Form 14039 after an IRS notice?
What the form is
Form 14039 is the IRS Identity Theft Affidavit for victims. The current form identified here is Form 14039 (Rev. February 2026). Its instructions provide online submission and mail or fax procedures. Use the route associated with your notice or case; the correct destination is not the same for every taxpayer.
When it may be appropriate
- Your legitimate e-filed return was rejected because a return using your SSN or ITIN was already accepted.
- The IRS specifically tells you to submit the affidavit.
- You have a confirmed tax-related identity-theft incident that is not resolved through the notice’s verification procedure.
When not to file it automatically
If you completed the Return Verification Service for a CP5071-series notice or Letter 5447C, IRS guidance says you do not need Form 14039 unless instructed. Likewise, receiving CP01A—the annual notice that supplies an IP PIN—does not, by itself, mean an identity-theft affidavit is required. A separate incident after receiving CP01A is a different matter.
Never submit a second affidavit for the same incident
The current form instructions say not to file another affidavit for the same incident. A duplicate can split correspondence across files and delay resolution. If you are unsure whether an earlier submission was received, use the instructions on your notice or the official IRS assistance channel rather than mailing another copy.
Why is my tax refund delayed after identity verification?
The Return Verification Service estimate
For returns verified through the IRS service, the IRS says to wait 2–3 weeks after verification before checking refund status. It also says processing may take up to 9 weeks after verification. These are estimates for that verification process, not a universal deadline for every identity-theft case, paper return, amended return, or refund notice.

A paper return filed after an e-file rejection, a Form 14039 review, a notice requesting additional documents, and a compliance or account review are separate IRS processes. Each can add its own processing time. A notice about a refund or account may tell you to wait and may state that calling will not speed payment; follow that notice rather than applying the Return Verification Service estimate to it.
Rank #4
What to do while waiting
- Confirm that you completed the exact action named in the notice.
- Check refund status only after the interval the notice or verification instructions provide.
- Watch your mail and online account for a request for evidence.
- Do not resend the same Form 14039 or create multiple cases to obtain an update.
Will I get my refund faster if I use my IP PIN?
No. The IRS IP PIN FAQ states, “How quickly you receive your refund depends on your individual return information.” An IP PIN helps prevent someone else from filing a fraudulent federal income-tax return with your SSN or ITIN, but it is not an expedited-refund service. Returns with an IP PIN go through the same validity checks that apply to other returns that do not require one.
How the IP PIN works
- It is a six-digit number issued by the IRS.
- It changes each year.
- Every taxpayer on a joint return who has an IP PIN enters that person’s own number.
- It applies to Forms 1040, 1040-NR, 1040-PR, 1040-SR, 1040-SS, and 1040-X, as listed in the IRS FAQ.
Who receives one
Confirmed victims of tax-related identity theft are automatically enrolled and issued an IP PIN annually. Other taxpayers with an SSN or ITIN may enroll if they can complete the IRS identity-validation requirements. The IRS describes online-account enrollment as the fastest and easiest method. People who cannot validate or access an account may have alternate options, including Form 15227 in qualifying cases or an appointment at a Taxpayer Assistance Center. Eligibility rules and thresholds can change, so check the current IRS IP PIN FAQ before applying.
What if you lose the number?
Retrieve the IP PIN through your IRS online account or follow the IRS phone-assistance procedure. If the IRS verifies your identity by phone, it says a replacement PIN is mailed to the address on record within 21 days. Do not guess the number.

What if the PIN is missing or wrong?
An e-filed return can be rejected when an assigned IP PIN is omitted or incorrect. A paper return may be held for identity review, delaying its refund. Correct the return using the IRS procedure rather than filing multiple competing returns.

Protect your accounts after a tax identity-theft incident
Monitor financial activity
Review bank, credit-card, and other financial accounts for unauthorized transactions. Check your credit reports for unfamiliar accounts or inquiries. Follow Federal Trade Commission recommendations for identity-theft victims and dispute activity through the channels those agencies provide.
Check your state tax account
Federal reporting does not automatically complete a state case. Contact your state tax agency to ask whether a fraudulent state return was filed and whether it requires a separate affidavit, PIN, or account lock. State procedures and deadlines vary.
Harden access and recognize phishing
- Use unique, strong passwords and multifactor authentication for email, financial, tax-preparation, and IRS online accounts.
- Keep devices and browsers updated and secure.
- Be skeptical of messages demanding immediate payment, a “refund release” fee, or a copy of your SSN. The IRS does not use an unsolicited email or text as a substitute for the instructions in your official notice.
- Do not give an IP PIN, account password, or verification code to someone who contacts you unexpectedly.
Understand the CP01 identity-theft indicator
An IRS CP01 identity-theft indicator does not prevent you from filing a return, paying tax, or receiving a refund. While the indicator is on the account, however, the IRS says an IP PIN must be used when you file.
How to keep the case from getting harder
- Use one consistent mailing address and keep it current with the IRS when required.
- Put the taxpayer identification number and tax year on correspondence only where the IRS instructions request them.
- Send complete copies, not irreplaceable originals, unless the notice specifically demands an original.
- Organize records by tax year: notice, return, affidavit, proof of delivery, IRS response, and your reply.
- Do not send a second return or affidavit merely because processing is slow.
- When the IRS requests information, answer every item and meet the stated deadline; if the notice gives no deadline, follow its contact instructions for clarification.
Common mistakes and the safer alternative
| Mistake | Why it causes trouble | Safer alternative |
|---|---|---|
| Using the Return Verification Service without a CP5071-series notice or Letter 5447C | The service is tied to those notices and may not address a different case. | Follow the actual notice or e-file rejection instructions. |
| Filing Form 14039 for every identity-verification letter | Some notices are resolved through verification and do not require an affidavit. | File the form only when the IRS process for your incident requires it. |
| Ignoring a rejected e-filed return | The legitimate return remains unfiled and any tax due remains unresolved. | File the accurate return on paper when IRS guidance says e-filing is unavailable. |
| Sending duplicate affidavits or making repeated status inquiries | The IRS warns that duplicates and repeated inquiries can delay the case. | Keep delivery proof, answer IRS requests, and wait for contact. |
| Assuming an IP PIN speeds a refund | The PIN is a fraud-prevention control, not a priority-processing code. | Use the PIN correctly and rely on the timeline for your specific process. |
| Trusting an unexpected “IRS” email, text, or caller | Phishers use tax-season urgency to collect credentials and identity data. | Verify through the notice and official IRS channels before disclosing information. |
What to expect after the IRS receives your response
The IRS may first match the response to the account, review the return and identity information, request documents, or refer a confirmed case to Identity Theft Victim Assistance. A paper filing can take longer than an electronic filing, and an identity-theft review can continue after the return itself is received. Keep monitoring mail and your account for a request, but do not create a second claim to force movement. Once the IRS resolves a confirmed case, it says it will contact you.
If your notice gives a specific deadline, that deadline controls. If you move, update your address through the method the IRS allows so that a follow-up letter does not go to an old address. If a tax professional prepared the return, give that professional copies of the rejection and notice, but remain responsible for confirming that the required filing and response were actually sent.
Quick Recap
Quick decision checklist
- Read the notice number. Identify whether it is CP5071-series, Letter 5447C, CP01A, or another notice.
- Check whether you filed the questioned return. If yes, verify it as directed. If no, report the possible attempted filing through the instructed service or channel.
- Check your e-file result. A rejection because the SSN or ITIN was already used generally requires a paper filing and the applicable identity-theft reporting steps.
- Decide about Form 14039 from the instructions. Do not infer that every notice requires it, and never submit a duplicate for the same incident.
- Use your IP PIN correctly. Enter each joint-filer’s current six-digit PIN on applicable forms; retrieve a lost PIN rather than guessing.
- Track, protect, and wait. Keep records, monitor accounts and credit, respond to IRS requests, and use only the timeline stated for your process.
