TaxSlayer Pro always supports current year Desktop and ProWeb software plus the four prior program years. Every calendar year, when the new program year is released, the oldest program year is retired from Support. Programs older than 5 years cannot be supported due to security updates, operating system compatibility, and many other factors.
For the year 2021, the supported software years are 2020, 2019, 2018, 2017, and 2016.
For the year 2022, the supported software years will be 2021, 2020, 2019, 2018, and 2017.
Reminder: TaxSlayer Pro Support agents, including Technical Support agents, cannot provide download links for or assist with any program older than 5 years.
