Although Texas allows businesses to use many of the same forms year to year, the TaxAct program does not support or allow business customers to use a different year’s product for the filing of another year’s report. A 2020 Federal return is needed to complete a 2021 Texas Franchise Tax Report. The 2021 report actually uses 2020 Federal numbers, but is labeled "2021" because it is filed during the 2021 calendar year.
If you are needing to file any year prior to the current year report, you will need to use the forms and instructions available on the Texas Franchise Tax Forms website.
Note that any link in the information above is updated each year automatically and will take you to the most recent version of the document at the time it is accessed.
