Do I need to file 2021 income before I file 2022 taxes or can I file them after I finish 2022 taxes?

I haven't filed 2021 taxes yet, so do I need to finish filing them before I finish filing 2022 taxes?

File your 2022 taxes immediately otherwise they will be late and subject to penalties (based on how much money you owe).  Then get to work on your 2021 return for which you have probably already incurred penalties at this point.  The longer you wait to file 2021 return the more penalties and interest you will pay in addition to your overdue taxes.

it depends on whether anything on the 2021 return would affect the 2022 return. if so, then you may later need to file an amended 2022 return.  if nothing on 2021 will affect 2022, then its your choice as to whether to file 2022 now (by midnight your time) or extend. Any balance due is due by midnight (no extension on paying).  if extended, you have until 10/15/2023 to file 2022  by which time you should know for sure about 2021s affect on 2022.
