The CP01 notice is sent by the IRS to provide taxpayers with their Identity Protection Personal Identification Number (IP PIN). This six-digit number is crucial for those who have been victims of identity theft or are at risk for it, as it helps ensure that only the taxpayer can file a return using their Social Security Number (SSN).
Key points about CP01:
- The IP PIN is used to validate the taxpayer’s identity when filing their tax return.
- Taxpayers must enter the IP PIN on their tax return to avoid delays or rejections.
- The IRS typically issues a new IP PIN each year, and taxpayers should keep this number confidential.
Taxpayers should use their IP PIN when filing to prevent fraudulent tax returns from being submitted under their name, thereby protecting their tax information and refund.
