What a Letter 5071C actually means

Letter 5071C is an identity verification request. The IRS wants confirmation that you filed the return submitted under your Social Security number.

The difference from Letter 4883C is the method. A 5071C points to an online identity verification service first, with a phone line as the backup route.

The letter includes a control number used during verification and lists the documents needed, usually the letter, the return in question, and the prior year return.

Common questions about Letter 5071C

What is Letter 5071C?

It is a request to verify your identity, online or by phone, before the IRS finishes processing a return filed under your Social Security number.

How long do I have to respond to Letter 5071C?

The letter prints a verification window, commonly 30 days from the letter date. Our tool reads that date from your copy.

What happens if I ignore Letter 5071C?

The return generally stays unprocessed and any refund for that year remains held until identity verification is completed.

Can I respond to Letter 5071C myself?

Yes. Verification is done through the service or phone number on the letter. Our tool produces a plain-English summary and a written record of the matter.

Is Letter 5071C serious?

It is a processing hold rather than a collection action, though the return stays in limbo until the verification step is finished.

How is Letter 5071C different from Letter 4883C?

A 5071C offers online verification with a control number. A 4883C directs you to a phone line as the primary route.
