We have identified an issue with Sage 100 2018 payroll for customers who are migrating impacting their Workman's Comp and states that have no personal income tax. We are going to release an update, 2.17.1, of payroll around November 3, 2017 for this issue. We ask that until this has been released you do not migrate your payroll data from a prior version of Sage 100 to the new version. These issues do not impact New Sage 100 customers.
