If you got a notice from the IRS, don’t worry. We’ll do our best to help you figure out what to do next.

The notice tells you about the 6-digit Identity Protection Personal Identification Number (IP PIN) and includes instructions on how to use it. This PIN is to help prevent the misuse of your Social Security number.

You can obtain more detailed info about the IP PIN from the IRS.

Once you have the PIN

  • Navigate to the IP PIN section:

    • TurboTax Online/Mobile: Go to the IP PIN screenunder Other tax situations in the Federal section .

    • TurboTax Desktop:

      • Go to Federal Taxes.

      • Go to Other Tax Situations.

      • Under Other Return Info, select Start or Update next to Identity Protection PIN.

    • On the Identity Protection PIN screen, answer Yes. Select Add and enter your IP PIN in the space provided.

      • If you need to remove the IP PIN, select the trash icon.

    • Select Continue, then select Done.
