IRS Letter 5071C: verifying your identity before a return is processed
A return was filed under your Social Security number or ITIN, and the IRS will not process it until you confirm it was yours, or tell it that it was not. There is no penalty clock, but nothing moves until you verify.
THE CLOCK — NO APPEAL DEADLINE, BUT NO PROCESSING UNTIL YOU VERIFY
A 5071C does not assess tax or start an appeal window. It holds the return. Until you verify, the IRS will not process it, issue a refund or credit an overpayment. After a successful verification, the IRS says a refund may take up to 9 weeks.
Why you received it
The IRS sends the CP5071 series, which includes CP5071, Letter 5071C and CP5071F, when a Form 1040-series return has been filed under your Social Security number or individual taxpayer identification number and it needs to confirm your identity and the return before processing it.
The letter works in both directions. If you filed the return, verifying lets the IRS carry on processing it. If you did not, verifying is how you tell the IRS, and you may be the victim of identity theft.
It is not an accusation and it is not a bill. It is a hold on one return, and the only way to release it is to respond.
Verifying safely
The IRS says that if your notice offers online verification, you can begin at irs.gov/verifyreturn. Type that address yourself rather than following a link from an email or text. The IRS says it normally makes first contact by mail, and it sends texts and emails only to people who have opted in.
The contact details on the letter are for identity and return verification only. The IRS says other information, such as refund status, may not be available through that route.
HAVE THESE READY BEFORE YOU START
- The letter itself
- The tax return for the year named on the letter
- A prior-year tax return, if you filed one and have it
- The supporting documents for each return: W-2s, 1099s, Schedule C, Schedule F and similar
- If you did not file, be ready to say so during the verification
A W-2 or 1099 is not a tax return. The IRS wants the Form 1040-series return itself.
Letter 4883C: the phone version
Letter 4883C does the same job by telephone. The IRS says to call the Taxpayer Protection Program hotline shown in the letter, with the letter, the return it refers to, a prior-year return if you have one, and the supporting documents for each.
If phone verification is not possible, the IRS says it will ask you to schedule an appointment and bring the same documents to a local IRS office. If someone else is helping you, the IRS needs a Form 2848 on file for them, or you must be on the call together and take part in it.
For both letters, the IRS is clear on one point: do not file Form 14039, the Identity Theft Affidavit, as a response to the letter. Verify instead, and file the affidavit only if the IRS tells you to.
After verification
Once you verify, the IRS processes the return. It says a refund may take up to nine weeks, and that if it finds another problem it will contact you again, which may delay the refund further.
If you told the IRS you did not file, the case moves into identity theft handling. The IRS offers an Identity Protection PIN, which it recommends to prevent someone from filing a return with your SSN or ITIN. It is the practical step against the same thing happening next year.
Where a return you did file sits unprocessed for months after verifying, the delay itself may meet the Taxpayer Advocate Service's criteria. TAS is free and independent within the IRS.

Is this IRS letter real?
The IRS almost always starts with a letter in the mail, and a genuine letter can be checked without using anything printed on it. The fastest check is your own IRS Online Account, which shows the same balances and notices the IRS holds.
Spotting a tax relief scam
The FTC and the IRS publish the same warning signs: a promise to settle for a fraction before anyone has looked at your finances, a fee demanded up front, and mail dressed up to look official. The free checks come from the IRS itself.
Taxpayer Advocate Service
An office inside the IRS whose job is to help when normal channels have failed: economic harm, a delay of more than 30 days, or a promised response that never came. It costs nothing, and Massachusetts has its own counterparts.
Authorizing someone to act
Two different authorizations that are constantly confused. One lets someone act on your behalf; the other only lets them see your file. Not everyone who can prepare your return can hold the first one.
Questions about letter 5071c.
- Is Letter 5071C a scam?
- Genuine 5071C letters exist and come by mail. The IRS says to begin online verification at irs.gov/verifyreturn if the letter offers it. Type the address yourself. The IRS normally makes first contact by mail, and texts or emails only if you opted in.
- Should I file Form 14039 after getting a 5071C?
- No, unless the IRS tells you to. The IRS says that if you verify your return you do not need to complete Form 14039. For Letter 4883C it says plainly not to file one, and to follow the letter's instructions.
- How long will my refund take after I verify?
- The IRS says it may take up to nine weeks after successful verification to receive a refund or have an overpayment credited. If it finds other problems, it will contact you again and the refund may take longer.
- Can my accountant verify for me?
- Not alone. For the phone route, the IRS requires a Form 2848 on file for an authorized representative and encourages you to be available too. Without one, you and the person helping you must call together and you must take part.
- What if I didn't file the return the letter mentions?
- Say so during verification. The IRS says you may be the victim of identity theft. After that, the IRS recommends getting an Identity Protection PIN to prevent someone filing a return with your SSN or ITIN in future years.
