If you are on an active support plan you are entitled to any product update that is released while your plan is active.
Please note that we only support and provide tax updates for the current version and one version back (Sage BusinessWorks 2020 and Sage BusinessWorks 2021) so now would be a great time to get updated before year end.
All products updates can be downloaded from www.sagekb.com and do require a login to access the downloads.
Instructions for the upgrade process can be found in article 51401 How to upgrade to the current version of Sage BusinessWorks Accounting
