The percentage method is used if your bonus comes in a separate check from your regular paycheck. Your employer withholds a flat 22% (or if over $1 million, 37% which is the highest rate of income tax). This percentage method is also used for other supplemental income such as severance pay, commissions, overtime, etc. Supplemental wages are still taxed Social Security, Medicare, and FUTA taxes.
