Users of Sage 100 Payroll 2.x should be aware of this issue which has just been listed by Sage as KB 113767.
Additional Medicare over $200k (.9%) and the ER & EE SS tips are not on the tax liability report.
Although Sage does not list a specific Payroll version this issue applies to, it’s likely that it is relevant to users of Payroll 2.21.3 released in October 2021.
Beginning with payroll version 2.x, all updates for the payroll module are applied separately from updates for the core Sage 100 accounting product.
Please check back with the KB listed above for the latest updates. It’s likely Sage will quickly release a fix for this reporting issue and you’ll be able to apply a hotfix prior to the year-end.
