Arizona Tax Calculator
Arizona has a flat 2.5% state income tax — among the lowest flat rates in the country.
Arizona enacted a flat 2.5% income tax rate in 2023, down from a previous 2.8%, with further reductions scheduled to 2.25% in coming years. The state also has a 5.6% state sales tax plus local additions that produce a combined rate of about 8.28% statewide and as high as 9.1% in some cities. Arizona conforms to most federal tax provisions and fully adopts the federal standard deduction. The flat-rate structure makes tax planning simple for residents and retirees, and the state has aggressively cut taxes since 2021 to attract Californians and remote workers. Property taxes sit below the national mean at ~0.63%. Arizona exempts Social Security benefits from taxation and offers a $2,500 subtraction for military retirement pay. The Phoenix metro area has been one of the fastest-growing in the US, with tax-friendly policies — combined with affordable housing compared to coastal states — driving much of that growth.
