RSU vesting tax in Wisconsin
RSUs (restricted stock units) are taxed as ordinary income when they vest. The fair market value (FMV) on the vest date is added to your W-2 wages. Employers typically withhold at the supplemental rate: 22% federal (37% above $1M), plus Wisconsin state supplemental withholding and FICA (6.2% Social Security up to the wage base, 1.45% Medicare). This calculator uses your state (Wisconsin) to estimate total withholding and how many shares are sold to cover tax.
Wisconsin state tax on RSUs
Wisconsin has state income tax, so RSU vesting in Wisconsin is subject to state withholding in addition to federal and FICA. High-tax states like Wisconsin, California, and New York withhold 10%+ on supplemental wages. Your take-home from RSU vesting in Wisconsin is lower than in no-tax states (Texas, Florida, Washington, etc.). The calculator above includes Wisconsin state supplemental rate.
Sell-to-cover and net shares in Wisconsin
With sell-to-cover, your employer sells some vesting shares to pay the tax and delivers the rest to your brokerage. Shares sold = Tax withheld ÷ FMV per share. The calculator shows how many shares you keep after federal, Wisconsin state, and FICA withholding. For full vesting schedules, use our Equity Vesting Calculator; when a tranche vests, use this tool for that vest event.
