Because Microsoft will no longer provide security updates or support for PCs running Windows 7, we strongly recommend that desktop customers using Windows 7 upgrade to Windows 10 before installing their product.
TurboTax for tax year 2019 will install on Windows 7, but when TurboTax for tax year 2020 is released, all TurboTax desktop products will cease installing on Windows 7.
And while you can still use TurboTax 2019 on Windows 7, there are a couple risks in doing so:
Your computer will be more vulnerable to security risks and viruses because Microsoft will no longer provide security updates and support for your PC.
You won’t be able to install future versions of TurboTax on your PC. You’ll need to upgrade to a newer version of Windows next year.
If you don’t want to upgrade your operating system now, you can use TurboTax Online to complete your taxes this year. These instructions can help you switch from TurboTax CD/Download to TurboTax Online.
