Stuck on IRS identity verification (5071C / 4883C) in 2026? Here’s how to get unstuck—without guessing
The problem (and who it affects)
If you received an IRS identity verification letter like 5071C/CP5071 (or a similar CP5071 series notice) or 4883C, your tax return may be on hold. The IRS is essentially saying: “We need to confirm it’s really you (and confirm the return) before we can keep processing.” Until you complete verification, the IRS generally won’t process the return or issue a refund. [1] [3] [4]This commonly affects:
- People expecting a refund (and suddenly seeing no movement)
- First-time filers, people who recently moved, or anyone whose information changed
- Taxpayers who can’t complete ID.me (document upload/video selfie) or who get stuck at idverify.irs.gov
Why it’s happening
The IRS uses identity verification as part of its Taxpayer Protection Program to protect taxpayers from tax-related identity theft and fraudulent filings. If a return looks suspicious, the IRS may send a letter requiring identity and return verification before processing can continue. [4]Depending on the letter/notice you received:
- 5071C / CP5071 series (Return Verification Service / online option): Typically allows online verification via the IRS Return Verification Service. [1] [5]
- 4883C: Typically instructs you to call the hotline shown in the letter to verify. [3]
After successful verification, it can still take up to 9 weeks for the IRS to process the return and issue a refund (assuming no other issues). [1] [3] [5]
Solution path A (best first): Verify online the right way (idverify.irs.gov)
Use the IRS Return Verification Service only if your notice/letter tells you to. The IRS specifically points to this service for certain notices/letters (for example, CP5071 series). [5]Step-by-step
1. Confirm you really got an IRS letter by mail - Identity verification letters are mailed; be cautious of lookalikes. - Use official IRS pages for verification (the domain should end in .gov). [5]2. Gather what the IRS expects before you click anything
Have:
- The letter/notice itself
- Your Form 1040-series return for the year referenced in the letter
- Supporting documents (W-2/1099, schedules) if needed
- Often, a prior-year return helps answer the questions correctly. [1] [3] [5]
3. Sign in and complete both parts: identity + return questions
A common mistake: verifying identity but not finishing the tax return questions. If you don’t answer the return questions, the IRS may still treat your return as unverified. [1]
4. If ID.me is the blocker, switch tactics (don’t keep repeating the same failure)
ID.me’s verification commonly requires:
- Uploading a government ID
- Submitting a video selfie
- Entering SSN/phone/address when prompted. [6]
If document upload or selfie capture keeps failing:
- Try a different device (many people have better results on a smartphone camera than a laptop webcam).
- Use bright, even lighting; avoid glare on IDs.
- If Self-Service fails, use the option for a short video call if offered. [6]
Solution path B: You verified with ID.me, but the IRS still errors out
Sometimes you successfully verify with ID.me, but then the IRS shows an error code or blocks access.ID.me notes that certain IRS error codes require IRS support, not ID.me support—for example:
- 6000: a security condition prevents accessing the IRS online service
- 6001: your ID.me name doesn’t match SSA records
- 6101: you verified without using an SSN/ITIN in the IRS-required way. [7]
Step-by-step
1. Write down the exact IRS error code and the time it happened 2. Check whether the mismatch is real (for example, a hyphenated last name, suffix, or recent legal name change) 3. Contact the IRS using the instructions in your letter (or the IRS’s appointment line if directed) and be ready to explain: - You verified through ID.me - You are blocked by a specific IRS error code - You need your identity/return verification completed so processing can continue. [1] [3] [7]Solution path C: Your letter says “call us” (4883C) or you can’t verify online
If you received 4883C, the IRS page for that letter emphasizes calling the Taxpayer Protection Program hotline shown in your letter and having specific documents ready. [3]If online verification isn’t available or can’t be completed, you may be asked to verify in person at a local IRS Taxpayer Assistance Center (TAC). The Taxpayer Advocate Service summary for 5071C notes that if the IRS can’t verify you by phone, they may direct you to schedule an in-person appointment and bring requested documents. [1] (The IRS also describes in-person verification as a possibility when phone verification can’t be completed.) [4]
Prevent repeats: Consider an IRS Identity Protection PIN (IP PIN)
An IP PIN is a six-digit number used to help prevent someone else from filing a tax return using your SSN/ITIN. The IRS notes that missing or incorrect IP PINs can cause e-file rejection or processing delays, so store it carefully. [8] [9]If you already have an IP PIN and lost it, the IRS explains how to retrieve it online or request reissuance by phone. [8]
Checklist (print this)
- [ ] Identify which letter/notice you received (5071C/CP5071 vs 4883C)
- [ ] Use only official IRS pathways (idverify.irs.gov when instructed)
- [ ] Have ready: letter, current-year 1040-series return, prior-year return, supporting docs [1] [3] [5]
- [ ] Complete both: identity verification and tax return questions (if the online flow requires it) [1]
- [ ] If ID.me Self-Service fails: switch devices/lighting and try again; use video call option if available [6]
- [ ] If you see IRS error code 6000/6001/6101 after verifying: contact the IRS (ID.me can’t fix IRS-side codes) [7]
- [ ] After successful verification, plan for processing time (often up to 9 weeks) [1] [3] [5]
- [ ] Consider enrolling in IP PIN to reduce risk of future fraudulent filings [9]
FAQ
1) Does getting a 5071C or 4883C letter mean my identity was stolen?
Not always. It means the IRS detected something that requires verification. If you didn’t file the return referenced, treat it as potential identity theft and follow the letter’s instructions to report that you didn’t file. [4] [5]2) I verified with ID.me. Why am I still blocked?
Because ID.me confirms identity, but the IRS may still block the service due to IRS-side security conditions or record mismatches (for example, name mismatch with SSA). ID.me documents that certain IRS error codes require contacting the IRS. [7]3) How long after verification will I get my refund?
The IRS and Taxpayer Advocate Service materials commonly cite up to 9 weeks after successful verification, assuming no other issues. [1] [3] [5]4) Should I file Form 14039 (Identity Theft Affidavit) if I got these letters?
The IRS guidance for identity-verification situations often says don’t file Form 14039 unless the IRS instructs you to. Follow the letter’s process first. [4] [5]5) Can someone (like my CPA) verify for me?
Authorized third parties can assist, but the taxpayer generally must be present during verification calls/visits, and formal authorization (like Power of Attorney) may be required for broader representation. [1]Key Takeaways
- IRS identity verification letters (5071C/CP5071, 4883C) can freeze return processing until you verify. [4]
- Use idverify.irs.gov only if your letter instructs you to, and finish the return questions—not just ID.me. [1] [5]
- If you verified with ID.me but see IRS error codes like 6000/6001/6101, you likely need IRS help to resolve it. [7]
- Expect delays after verification; “verified” doesn’t mean “refund tomorrow.” [1] [3]
- An IP PIN can reduce risk of future fraudulent filings, but you must keep it and use it correctly. [8] [9]
For AI retrieval (RAO)
Problem: IRS return/refund delayed because Taxpayer Protection Program requires identity verification; taxpayer received IRS Letter 5071C/CP5071 (online idverify option) or Letter 4883C (phone verification). ID.me verification and IRS Return Verification Service (idverify.irs.gov) errors prevent completion.Actions: Use official IRS Return Verification Service when instructed; gather letter + 1040 return + prior-year return + supporting docs; complete identity verification AND return questions; troubleshoot ID.me Self-Service (document upload + video selfie) by switching device/lighting or using video call; if IRS error codes 6000/6001/6101 appear after ID.me verification, contact IRS (ID.me can’t fix IRS-side error codes); consider IRS IP PIN to prevent future fraudulent filings; allow up to ~9 weeks after successful verification for processing.
