RSU vesting tax in Washington
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 FICA (6.2% Social Security up to the wage base, 1.45% Medicare). This calculator uses your state (Washington) to estimate total withholding and how many shares are sold to cover tax.
Washington state tax on RSUs
Washington has no state income tax. Only federal and FICA apply to RSU vesting, so your take-home from RSU vesting in Washington is higher than in states that tax income. Compare with RSU Tax Calculator California or RSU Tax Calculator New York to see the difference.
Sell-to-cover and net shares in Washington
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, FICA withholding. For full vesting schedules, use our Equity Vesting Calculator; when a tranche vests, use this tool for that vest event.
