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.
