Letter 4883C and Letter 5747C come from the IRS Taxpayer Protection Program, which flags returns that look like they were filed by someone using another person's name and Social Security number. Both ask you to verify your identity and the return in question. They differ in how: 4883C asks you to call, and 5747C asks you to come to an IRS office in person. Until you respond, the IRS will not process the return or issue a refund.
Why the IRS sends them
The Taxpayer Protection Program stops returns filed with your name and SSN that show signs of potential identity theft, then writes to the real taxpayer. According to the IRS, the letters ask you to verify your identity and say whether you filed the return. The return is not processed and no refund is issued until you respond.
If you did not file, the IRS removes the return from your records. If you did file, processing continues, and your refund is issued if there are no other issues.
The three letters compared
| Letter | How you verify | Notes |
|---|---|---|
| 5071C | Online, with a phone option | Starts at the IRS verification service named in the notice |
| 4883C | By phone | Use the toll-free number printed on the letter |
| 5747C | In person, by appointment | At a local IRS Taxpayer Assistance Center |
What to have ready
For the phone call or the visit, the IRS suggests having:
- The letter itself. It is recommended for an in-person visit even if not strictly required.
- A copy of the Form 1040-series return referenced in the letter, if you filed it.
- A copy of a prior-year tax return, if you filed one.
- Photo identification for an in-person visit.
Gather W-2s, 1099s and any supporting schedules for the year in case the representative asks about them.
On the call or at the office
Answer the identity questions, state whether you filed the return, and confirm return details if you did. The identity-verification line is for verification only. Do not expect to discuss refund status or other tax account matters on that call.
Write down the date, the time and the name or ID number of the person you spoke with. If you are using a representative, the IRS requires an authorization, and the process may still need you to be present.
If you did not file the return
Tell the representative so. The IRS will remove the fraudulent return from your record and add protection to your account. Once your case is confirmed, you will be enrolled in the Identity Protection PIN program and receive a new six-digit IP PIN each year, which must be used on all future filings. Ask about other tax years and about your dependents too. See identity theft and the IRS.
Interest and penalties
These letters do not assert a balance. But verification does not extend a filing or payment deadline for a return you did file, so any tax due should still be paid on time.
Common mistakes
- Filing Form 14039 in response to these letters. The IRS says it is not needed.
- Calling a number from a web search or text message rather than the number on the paper letter.
- Showing up without the letter or photo ID.
- Failing to bring or look up the return the letter refers to.
- Assuming the letter is fake because you were not expecting it. Verify it using the steps in our scam guide.

Frequently asked questions
Do I have to go to an IRS office?
Only if your letter is a 5747C or the IRS asks you to after a phone attempt. Letter 4883C is a phone process.
What if I did not file a return?
Tell the IRS so. It will remove the return and protect your account.
Do I file Form 14039?
No. The IRS says you do not need Form 14039 in response to these letters.
How long does the process take?
The letters do not promise a timeframe. Respond promptly. If you do not respond, the IRS cannot process the return or issue the refund.
