After the last payroll of 2015 and before your first checks are issued in 2016 you should apply the latest Sage 100 payroll tax tables. The Q1 2016 tables are available for download to anyone with an active Sage Business Care subscription.
Best practices for payroll indicate that you should test some of the tax calculations from your first payroll run of 2016. In order to do this you will need the IRS Circular E – Employer Tax Tables – for 2016 which contain the rates and schedules necessary to manually compute withholding.
Verifying that the deductions are properly computing during the first check run of the new year can save you lots of time should there be an adjustment needed in order to fine tune the computations.
