When running a Scheduled Payroll, payroll taxes are not calculating and the message "Special Calculation Situation" is displayed.
Note - certain payroll items such as State Unemployment, FICA or other items where the setup is defined through payroll updates cannot be duplicated. For these items, running Payroll Checkup should resolve the issue.
The Payroll Checkup will examine each facet of the payroll configuration starting at the employee level all the way through the actual paycheck calculations. This tool is extremely useful as it will identify missing information as well as check the year to date calculations to identify any adjustments that should bring the payroll to an accurate state.
