06 January 2020 State supplemental income tax withholding rates for 2020 Similar to the federal supplemental income tax withholding rate, most states also allow for an optional flat percentage of income tax withholding for wages that are in addition to regular pay. Where allowed, the supplemental rate greatly simplifies income tax withholding calculations on irregular payments such as bonuses, equity compensation and separation pay. Employers may optionally use a federal flat rate of income tax federal withholding of 22% on supplemental wages up to $1 million for the year; however, a mandatory flat rate of 37% applies to supplemental wages in excess of $1 million. Note that the flat 37% rate applies even if an employee has submitted a federal Form W-4 claiming exemption from federal income tax withholding. The state supplemental income tax withholding rates that have thus far been released for 2020 are shown in the chart below. Changes from 2019 are highlighted in yellow.
