What's an IP PIN? Do I need one?

An Identity Protection PIN (IP PIN) is a 6-digit number that the IRS gives taxpayers who were victims of tax-related identity theft.

The IP PIN validates a Social Security number's true owner and prevents future tax fraud. Most taxpayers don't need one.

However, if you got an IP PIN or CP01A notice from the IRS in the past (or you opted in to the pilot program), you must use your 2024 IP PIN to prove your identity when you file your 2024 return.

We can't issue IP PINs and you won't find them on your tax paperwork. You can only get IP PINs from the IRS.
