Got an IRS 5071C Letter?
A 5071C means the IRS wants to confirm that you, and not someone using your Social Security number, filed a tax return. Your refund is on hold until you verify, but most people can do this themselves for free in a few minutes.
What a 5071C actually is
Letter 5071C is an identity-verification request. The IRS received a tax return filed under your Social Security number and its fraud filters flagged it as possibly not yours. Rather than process a return that might be fraudulent, the IRS pauses it and asks you to confirm your identity first.
It is not a bill, not a penalty, and not an audit. It usually is not a sign that you did anything wrong. In many cases the return is genuinely yours and the filter simply triggered on a change of address, a new device, or a return that looked different from prior years.
The 5071C has close relatives. A 5747C asks you to verify in person at a Taxpayer Assistance Center, a 4883C asks you to verify by phone, and a 6331C works the same way as a 5071C. Read the letter you received: it tells you exactly which verification path applies to you.
Most people can verify for free, without paying anyone
The honest first step is not to hire anyone. The fastest route is the IRS Identity Verification Service at idverify.irs.gov, or the phone number printed on your specific letter. Have the 5071C in front of you, the tax return it refers to, and a prior-year return, plus supporting documents like your W-2s and 1099s. Verification often takes only a few minutes.
Watch out for scams. A genuine 5071C arrives by postal mail, never first by email, text, or phone call. Verify only through the official idverify.irs.gov page reached by typing irs.gov yourself, or the number on the letter. Never click a link in an email or text claiming to be this letter, and the IRS will not ask for payment or gift cards to verify your identity.
If the return was not filed by you, you can say so during verification. The IRS will pull the fraudulent return, stop the refund from going to the thief, and begin its identity-theft procedures. From there you would typically file Form 14039, the Identity Theft Affidavit, if instructed, and enroll in the Identity Protection PIN (IP PIN) program so a six-digit code is required on every future return filed under your SSN.
Your deadline
There is no fixed statutory clock on a 5071C the way there is on a CP2000 or a Notice of Deficiency. But nothing moves until you verify: the flagged return is not processed and no refund is released, so the practical answer is to act promptly.
The longer a legitimate return sits unverified, the longer your refund is delayed. If a thief filed in your name, verifying quickly is also what lets the IRS shut the fraudulent return down and protect your account, so treat it as time-sensitive even though no penalty date is printed on the letter.
What to do, step by step
- 1
Confirm the letter is real
A genuine 5071C comes by mail and references a tax return. Do not act on any email or text version. Go to idverify.irs.gov by typing irs.gov yourself, or call the number printed on the letter.
- 2
Gather your documents
Have the 5071C letter, the tax return it names, a prior-year return, and supporting forms like your W-2s and 1099s ready before you start. Verification asks questions only the real taxpayer can answer.
- 3
Verify online first, then by phone if needed
The online Identity Verification Service is usually fastest. If you cannot complete it online, use the phone option on your letter. A 5747C means you must verify in person at a Taxpayer Assistance Center; a 4883C means verify by phone.

If the return is not yours, say so
Tell the IRS during verification that you did not file it. They will remove the fraudulent return, protect the refund, and start identity-theft handling. File Form 14039 (Identity Theft Affidavit) if you are instructed to.
- 5
Get an Identity Protection PIN going forward
Enroll in the IP PIN program at irs.gov so future returns under your SSN require a six-digit code. This blocks most repeat fraudulent filings.
- 6
Keep records and watch your refund status
Note the date you verified and keep the letter. Once verified, a legitimate return generally resumes processing; you can track it through the IRS refund tools.
