This is my second year doing tax returns and first time encountered where client has a CA01A. I'm preparing 2021 and 2022. I do have the 2 letters from the IRS for taxpayer and spouse for 2021. Question is they will have another/different 6 digit number for 2022 - right?
You use the most current IPPIN no matter which tax year youre preparing, so ANY returns submitted in 2023 you'll use the IPPIN issued in the letter received in January 2023.
