IRS Letter 5747C Notice: In-Person Identity Verification Required
A Letter 5747C means the IRS requires you to verify your identity in person at a Taxpayer Assistance Center before it will process the return filed under your SSN — the strictest form of IRS identity verification, with no online option.
What a Letter 5747C actually means
The 5747C is the top tier of the IRS's identity-verification ladder (5071C allows online or phone; 4883C is phone-only; 5747C is in person). It typically means the fraud filters flagged the return strongly enough that the IRS wants to see you and your documents face to face before anything moves.
The appointment itself is straightforward — the pain is logistics. Taxpayer Assistance Centers are appointment-only, slots book out weeks in some cities, and arriving without the right documents means rescheduling. Booking immediately and over-preparing the paperwork is the whole strategy.
What to do, step by step
- 1Call the appointment line in the letter right away to book the Taxpayer Assistance Center visit — slots are the bottleneck.
- 2Bring the letter itself, a current government photo ID, a second identity document, a copy of the tax return referenced in the letter (if you filed it), and your prior-year return.
- 3If you did NOT file the return in question, bring that fact to the appointment — the IRS will pull the fraudulent filing and start identity-theft procedures (Form 14039, an Identity Protection PIN going forward).
- 4After verifying, expect processing to resume within about 9 weeks; track it via Where's My Refund or your online account.
- 5Consider opting into the IP PIN program afterward — it blocks anyone else from e-filing under your SSN in future years.
Common questions
Why does my letter require in-person verification when others verify online?+
The verification method matches the risk score the return triggered. A 5747C generally means stronger fraud indicators — or prior failed verification attempts — so the IRS requires physical documents in front of an employee. You can't downgrade to the online tool; it will reject a 5747C case.
What documents do I need for a 5747C appointment?+
The letter, a current government-issued photo ID (driver's license, state ID, or passport), one additional identity document, a copy of the referenced tax return if you filed it, and a prior-year return. Bringing supporting documents for the return's income (W-2s, 1099s) avoids a second trip if questions come up.
Someone filed a return in my name — is the 5747C how I fix that?+
It's step one. At the appointment, tell the IRS you didn't file; they'll remove the fraudulent return so your real one can process, and set you up with identity-theft protections including the Identity Protection PIN, which prevents future e-filings under your SSN without your annual PIN.
