Arizona recently moved to a flat 2.5% tax rate, significantly simplifying the state tax system. Its 2026 standard deduction ($15,750 single) is set by state law rather than copied from the federal amount. Arizona also allows taxpayers who take the standard deduction to deduct an additional amount for charitable contributions — a rare benefit not available in most states. Arizona has no local city income taxes, making it one of the simplest states for paycheck calculations. Arizona uses Form A-4 for state withholding elections, allowing workers to choose their withholding percentage.
Arizona charges a flat 2.5% state income tax on all taxable income in 2026 — one of the lowest flat rates in the United States. Arizona's standard deduction is $15,750 for single filers and $31,500 for married filing jointly, set by state law slightly below the 2026 federal amounts ($16,100 / $32,200).
No. Arizona does not have local city income taxes. The only state income tax is the 2.5% flat rate charged statewide. This makes Arizona paycheck calculations simpler than states like Ohio or Michigan where city taxes apply.
Arizona's 2.5% flat rate is among the lowest of any flat-tax state. For comparison in 2026: Indiana 2.95% (plus county tax), Pennsylvania 3.07%, Michigan 4.25%, Colorado 4.40%, Illinois 4.95%. Arizona's combination of a low flat rate and no local city taxes makes it one of the most paycheck-friendly flat-tax states.
Arizona's standard deduction is $15,750 for single filers, $31,500 for married filing jointly, and $23,625 for head of household in 2026, as set by Arizona legislation (HB 4168). That is slightly below the 2026 federal standard deduction, so the calculator applies the Arizona amounts separately.
