Sage advises that users of Sage 100 Payroll must upgrade to Sage 100 v2020.x (or higher) before the end of 2023. If you are a payroll user on a version of Sage 100 prior to 2020 then you won’t be able to load the year-end payroll update and will be unable to print or eFile W2 or 1099 or related tax forms.
The reasoning behind this is explained in Sage KB 119228:
Due to compatibility issues with the latest software provided by our tax reporting partner, the Sage 100 Payroll 2.24 release and 1099 update scheduled for December of this year will not be compatible with versions of Sage 100 before 2020 (6.20.0). Specifically, payroll customers and those utilizing 1099 functionality running Sage 100 versions 2018 and 2019 must upgrade to a supported version of Sage 100 to install the Payroll 2.24 release and the latest tax form updates.
Important Note: Customers running unsupported legacy payroll versions do not have the option of a separate payroll installation and are not impacted by this change.
Effective with the release of Payroll 2.24, payroll and 1099 customers on versions 2018 and 2019 will need to be running one of the following versions of Sage 100 to install the latest release of Payroll and 1099 forms:
Customers not running a compatible version of Sage 100 will experience a failure of the Payroll update installation and the inability to generate 1099’s, W-2’s or associated tax reporting documents.
Starting with our 2024 Payroll release, we will have an n-3 support policy for payroll updates, compatible with the latest and three prior versions of the Sage 100 software.
