RSU vesting tax in Arizona

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 Arizona state supplemental withholding and FICA (6.2% Social Security up to the wage base, 1.45% Medicare). This calculator uses your state (Arizona) to estimate total withholding and how many shares are sold to cover tax.

Arizona state tax on RSUs

Arizona has state income tax, so RSU vesting in Arizona is subject to state withholding in addition to federal and FICA. High-tax states like Arizona, California, and New York withhold 10%+ on supplemental wages. Your take-home from RSU vesting in Arizona is lower than in no-tax states (Texas, Florida, Washington, etc.). The calculator above includes Arizona state supplemental rate.

Sell-to-cover and net shares in Arizona

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.
