    CCH Software News – Compatibility with Microsoft Windows 11 Operating System

    Dear CCH Customer:

    At this time, we are unable to officially support our 2021 software products on the new Microsoft® Windows® 11 operating system for the upcoming tax season. While preliminary testing against the preview versions has shown positive results, the final release candidate of Windows® 11 has not yet been released to us, and therefore we have been unable to test our 2021 software for full compatibility with Windows® 11.

    After the final release candidate for Windows® 11 is released to us, we will commence our compatibility testing. The projected official release of Windows® 11 is late 2021, and, as such, we do not anticipate officially supporting the new operating system for the 2021 tax filing season.

    We will communicate any change in the support policy for our 2021 software once Microsoft® officially releases the operating system and our compatibility testing is complete. See the Microsoft® website for more information on Windows® 11.


    Wolters Kluwer Tax & Accounting, North America

    Wolters Kluwer is one of several main tax software vendors in the US.  This is pretty typical for line of business applications, I just thought it interesting that they go so far as to indicate that they probably won’t support it for the entire tax season (typically January through April 15th).
