Can I file my 2021 taxes without having to purchase the software?

No, you need to use a previous year product (2021) that must be installed and run on a computer.

You can fill out the blank forms.  Here are some basic ones.

Don’t forget your state.  And you will have to print and mail your returns.  So be sure to attach copies of your W2s and any 1099s that have withholding on them.  You have to mail federal and state in separate envelopes because they go to different places.  Get a tracking number from the post office when you mail them for proof of filing.

Then when you file for 2022 you need to enter 0 for the 2021 AGI since you are filing 2021 late.
