CP5071 (Letter 5071C): The IRS Wants Proof You Filed That Return
A CP5071 series notice means a federal income tax return was filed under your Social Security number or ITIN, and the IRS stopped it at the door pending identity verification. If you filed the return, verifying lets processing continue. If you did not file it, verifying is how you flag possible identity theft. Either way, nothing happens with the return, including any refund, until you respond.

Why this letter exists
The IRS screens returns for identity theft before processing them, and this notice is the screen firing. Its own framing is two branches: "If you didn't file a return: Verify with us. You may be the victim of identity theft," and "If you did file a return: Verify so we can continue processing your return."
One naming note so you can find things: the IRS has folded the old Letter 5071C into what it now calls the CP5071 series (CP5071, CP5071C, CP5071F). If your letter says 5071C or 6331C, the same instructions apply.
How to verify
If your notice offers online verification, start at irs.gov/verifyreturn and follow the prompts with your notice in hand.
If not, call the telephone number printed on your notice. The IRS notes that contact information is for identity and tax return verification only, so other questions need the general lines.
After verifying, expect patience: the IRS says it may take up to 9 weeks to process your return after verification, and to wait 2 to 3 weeks before checking your refund status.
If you never filed
Verification is also the fraud alarm
Verifying and telling the IRS you did not file the return is what stops the suspicious filing from processing. That path can lead to identity theft procedures such as Form 14039 and an Identity Protection PIN for future years, and it protects your account rather than delaying it.
CP5071 questions
Is a CP5071 notice bad news?
It is a checkpoint, not an accusation. Either you filed and the IRS wants confirmation before releasing processing, or someone else filed under your number and the notice is what catches it. The only bad outcome is ignoring it, because the return and any refund stay frozen until you verify.
How long after verifying will I get my refund?
The IRS says processing can take up to 9 weeks after verification, and suggests waiting 2 to 3 weeks after verifying before checking refund status. Verification restarts processing; it does not jump the queue.
Is 5071C the same as CP5071?
Yes. The IRS has rebranded the old Letter 5071C as the CP5071 series notice, and its pages now serve the same instructions for both names, including the related 6331C letter.
What if I cannot verify online?
Use the phone number printed on your notice. If the IRS needs more than the online or phone check can provide, it sends the phone-only 4883C or the in-person 5747C variant instead, each with its own process.
