Quick answer
A return was filed under your Social Security number or ITIN, and the IRS wants you to verify in person that it was really you before it processes anything.
What is an IRS Letter 5747C notice?
A return was filed under your Social Security number or ITIN, and the IRS wants you to verify in person that it was really you before it processes anything.
A Letter 5747C is a request to confirm identity before a refund is released. It is not an accusation of wrongdoing. For the IRS's own overview of notices and letters, see the official Understanding Your IRS Notice or Letter page on IRS.gov.
What does a Letter 5747C look like?
A genuine Letter 5747C is a paper notice with the notice number "Letter 5747C" printed in the upper-right corner, the tax year it concerns, a short plain summary of the issue, the amount involved (if any), and a section explaining how and by when to respond.
When reading a Letter 5747C, it helps to locate four things: the notice code (so you know which notice it is), the tax year it applies to, any dollar amount, and the response or payment date. Those four details tell you most of what the notice is about.
Why did the IRS send a Letter 5747C?
The return triggered the IRS identity protection screen, which exists to stop a refund going out on a return you did not file.
Is a Letter 5747C real, or a scam?
Scam letters sometimes imitate IRS notices. A real Letter 5747C arrives by mail, shows an official notice number, and never demands payment by gift card, wire, or cryptocurrency, and never threatens immediate arrest.
- • The IRS generally makes first contact about a notice by mail, not unsolicited email, text, or a phone call.
- • Real notices reference a specific tax year and a notice number like Letter 5747C.
- • The IRS does not demand gift cards, wire transfers, or crypto, and does not threaten immediate arrest or deportation.
- • When unsure, verify by calling the IRS directly at 1-800-829-1040 or the number listed on IRS.gov.
How time-sensitive is a Letter 5747C?
The response date for a Letter 5747C is the date printed on the notice itself. Always go by that printed date and confirm it against your own copy — do not rely on a general estimate.
What happens if you don't respond to a Letter 5747C?
Ignoring an IRS notice generally makes the situation harder to resolve — interest and penalties can continue to build, and the IRS can send further notices or take further action. It is almost always better to review the notice and respond by the printed date.
General next steps
In general, these are some of the steps people take for this type of notice — not advice about your specific situation.
- Read the Letter 5747C in full and note the notice code (top-right corner), the tax year, and any date it lists.
- Compare the amounts and any change shown on the notice against your filed return and your own records.
- Respond only in the way the notice itself describes, and by the date printed on it.
