Microsoft no longer supports PCs running Windows 8.1. This means that any data on your computer, including your tax data, may have increased exposure to security risks. For tax year 2022, you’ll need Windows 10 or higher to install TurboTax CD/Download.
Older versions (tax years 2019, 2020, and 2021) of TurboTax CD/Download are compatible with Windows 8.1 and higher.
If you use TurboTax Online, there’s no impact to you as long as you meet the minimum system requirements.
