Yes, QuickBooks Desktop (QBDT) 2024 is the latest version that you can upgrade from 2021, ljameson. I'll provide more details about this below.

QuickBooks Desktop 2021 will discontinue after May 31, 2024. You'll want to upgrade to a supported version like 2024 to continue access to live technical support for Intuit services (payroll, payments, and online bank feeds).

Please see this article to guide you on how to upgrade to a newer version of QBDT: Upgrade QuickBooks Desktop Pro, Premier, or Enterprise.

Additionally, QBDT 2024 has better data security, more productivity, and a better view of inventory levels. To know what features are included in its latest release, you can check out this article: What’s new in QuickBooks Desktop 2024.

Why do you consider upgrading to QBD 2024?

Only so we maintain full functionality of the DT software for a few more year. In the meantime, we're also buying quicken for a 'test drive'.  

You are using QB Desktop with a non subscription license. You can still use it for good. Do you have any other concern?
