Open RSU Tax Calculator →RSU vesting in Arizona triggers a flat 2.5% state income tax, treated as ordinary income just like your salary. Your employer typically sells shares at vesting to cover the combined federal, state, and FICA withholding, which can consume 35-50% of the vested shares depending on your income level. This calculator shows you exactly how many shares (or dollars) you keep after all Arizona tax layers are applied.
Arizona levies a flat 2.5% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 2.5 cents goes to Arizona. Arizona does not impose local income taxes, so the 2.5% flat rate is the only state-level income tax you owe.
