IRS Notice LTR5747C: Identity Verification — In Person

What does an IRS LTR5747C notice mean?

A 5747C letter directs you to verify your identity in person at a local IRS Taxpayer Assistance Center, rather than online or by phone. The IRS uses it when a return filed in your name needs a higher level of identity confirmation before it can be processed.

Why did you receive a LTR5747C?

The IRS flagged the return as potentially fraudulent and determined that in-person verification is necessary, often because online or phone verification was not possible or sufficient.

How to respond to a LTR5747C notice

Schedule an appointment at the Taxpayer Assistance Center listed and bring the required documents — typically the 5747C letter, the tax return in question, a prior-year return, and government-issued photo identification plus supporting documents. If you did not file the return, report it as identity theft during your visit.

What happens if you ignore it?

Your return remains unprocessed and any refund frozen. Unresolved fraudulent returns can complicate future filings and lengthen the identity-theft resolution process.
