Withholding

Supplemental rate

Wisconsin allows two methods for withholding on supplemental wages:

  1. Aggregate Method: Add supplemental wages to regular wages for the current or preceding payroll period, compute tax on the total, and subtract tax already withheld.
  2. Flat Percentage Method: Employers may use a flat percentage based on income brackets.
