What this notice usually means
IRS Notice CP01C tells you the IRS verified your identity theft claim and found no tax related fraud on your account. The IRS placed an identity theft indicator on your account and will monitor it to help prevent future fraud. This notice does not mean you owe money. It is a record keeping step tied to your identity theft report.

“We verified your identity theft claim and found no tax-related fraudulent activity. We placed an identity theft indicator on your tax account and will monitor it to help prevent future fraud.”
“File your federal tax returns on time.”
“The indicator will stay on your account until you specifically request that we remove it.”
What to do now
- 1
File your future returns on time
The indicator does not stop you from filing. Keep filing your federal tax returns by the deadline each year.
- 2
Pay any tax you owe by the due date
If you owe tax, pay by the due date on your notice or return to avoid interest and penalties.
- 3
Look into a payment plan if needed
If you cannot pay in full, you can view your payment options or set up a payment plan.
- 4
Consider an IP PIN for extra protection
You can ask for an Identity Protection PIN. Just make an online account for extra safety on future returns.
