Educational estimate. In supplemental-withholding mode, federal is a withholding estimate while state is modeled as incremental state income tax because state bonus-withholding rules vary. FICA is modeled as employee payroll withholding on the wages entered: Social Security respects the per-worker wage base, Medicare is 1.45%, and Additional Medicare withholding starts after this employee's wages exceed $200,000. Final Additional Medicare Tax liability can differ based on filing status and a spouse's wages.
