How many years can be efiled

[Jesse57]

I am helping a client who has to file Forms 1040 for 2020-2024.  I had myself convinced I could efile three of those but 2020 and 2021 would have to be paper filed.  Just checking if that is still correct or can I efile either 2021 and 2020 ?

You are correct.

Current year 2024 and 2 prior years - 2023 and 2022 are all that can be efiled.
