Identity and verification
CP01C
Identity claim reviewed — no tax fraud found
What this notice is
A CP01C says the IRS reviewed your identity theft claim, found no tax-related fraudulent activity, and still placed a protective indicator on your account as a precaution. It is a good outcome with a monitoring plan attached.
What the IRS is generally saying
Does this type carry a deadline?
Nothing is owed and nothing is wrong at the IRS. The remaining work is ordinary identity hygiene — credit monitoring, the optional IP PIN — done on your own schedule.
What people usually gather
- The notice, for your records
- Credit reports from the three bureaus
- An IP PIN application, if you want the added lock
- Nothing for the IRS — no response is requested
What a licensed professional handles
- Setting up the IP PIN and building it into future filings
- Reviewing account transcripts for anything the initial check might have missed
- Coordinating non-tax identity protection steps
- Being the contact point if anything suspicious surfaces later
This explanation of the notice type is compiled from the IRS’s own published description (retrieved 2026-08-21): irs.gov/individuals/understanding-your-cp01c-notice. It describes the notice type in general — not your letter, and not your situation.
The next step
Holding a CP01C and want it handled?
Fifteen quiet minutes with a licensed professional usually settles what a letter means and what the sensible next step is. No pressure, no scare tactics, and nothing sensitive needed to start the conversation.
