✅ What Is a CP5071 Series Notice?
The IRS issues a CP5071 notice (CP5071, 5071C, or CP5071F) when a federal income tax return was filed using your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and the IRS must verify the identity of the filer.
This notice does not mean something is wrong—only that the IRS needs additional verification before completing processing of the return.
✅ Why Did You Receive This Notice?
You may receive a CP5071 series notice if the IRS needs to confirm your identity.
- Verification is required whether or not you personally filed the return.
- The IRS must confirm your identity before processing your return.
✅ What You Need to Do Next
Follow the instructions printed on your notice. Your next steps depend on whether you filed a return.
If You Filed the Return
You must complete an identity verification process so the IRS can continue processing your tax return.
Be prepared to provide:
- The tax return for the year listed on the notice
- A prior‑year return (if available)
- Supporting documents: W‑2s, 1099s, Schedule C/F documents, etc.

If You Did Not File a Return

During verification, be sure to let the IRS know that you did not file a return.
