Today is Oct 11, 2023 but I have not filed my 2021 taxes. How can I file 2021 taxes before I tackle 2022?

1)   Your 2021 taxes must be prepared using the purchased desktop software, on a full MAC or Windows computer....and filed by mail..on paper...at the post office.  2021 can no longer be e-filed...unless you go to your  local professional tax preparer.    TTX software for 2021 can be purchased for download and installation here:

2)  Only your 2022 taxes can thus be prepared using TTX "Online" now...and until 16 October.   So if you want to do 2021 first (using step #1 above) you'd need to work fast.  (or just deal with 2021 later) 

Even so, when you attempt to e-file your 2022 tax forms by 16 October, you will indicate that you didn't file in 2021, or that your 2021 AGI is ZERO, because the IRS e-file system does NOT have your 2021 taxes as having been filed (even if you mail them in tomorrow, your 2021 taxes will take months to get manually processed)
