Arizona Income Tax Rate
2.50% flat rate
Everyone pays 2.50% of taxable income, regardless of income level or filing status.
Key Facts That Affect Your Take-Home Pay
- Arizona uses a progressive income tax system with four brackets, starting at 2.5% for the first $27,808 of income (single) or $55,615 (married) and escalating to a top rate of 4.5% for income above $166,843 (single) or $333,684 (married), making Arizona's top rate one of the lowest among progressive states.
- Arizona's progressive brackets are relatively spread out compared to compressed bracket states like Virginia or Georgia, meaning taxpayers don't reach the top rate until higher income levels. For a $75,000 earner, income is taxed at 2.5%, 3.3%, and 4.2%, creating an effective rate around 3.5%-4%, not the top 4.5% rate.
- Arizona does not charge income tax at the local level, ensuring uniform tax withholding across the state. All Arizonans have the same income tax structure—only the state progressive brackets apply.
Common Mistakes People Make
Misconception: 'Progressive tax means I'll pay the top 4.5% on all my income in Arizona.' Reality: Arizona's progressive system starts at just 2.5% for the first $27,808-$55,615 of income (depending on filing status), and most middle-income earners pay effective rates around 3%-4%, not 4.5%. The 4.5% rate only applies to income above $166,843 (single) or $333,684 (married). Someone earning $75,000 pays an effective rate around 3.5%-4% (~ $2,625-$3,000 annually), while the same earner in a flat-tax state like Illinois would pay $3,713 (4.95% flat).
Misconception: 'The brackets mean my tax is complex.' Reality: Arizona's brackets are relatively straightforward with only four brackets, and the rates are low (2.5%-4.5%). Unlike states with many brackets and high rates, Arizona's progressive system is simple to understand and relatively gentle on taxpayers across income levels The brackets are also spread out, meaning you don't quickly jump to the top rate like in compressed bracket states.
Misconception: 'Arizona taxes all retirement income like other states.' Reality: Arizona exempts Social Security and most retirement income (pensions, 401(k), IRAs) from state income tax, making the state very attractive for retirees. Combined with the low income tax rates (2.5%-4.5%), Arizona is one of the most tax-friendly states for retirees, even compared to zero-income-tax states that may tax retirement income differently or rely more heavily on sales or property taxes.
One Thing to Know
Arizona's brackets are unusually spread out compared to compressed-bracket states—a $75,000 earner pays three different rates (2.5%, 3.3%, 4.2%) rather than hitting the top rate immediately. This means small raises actually feel meaningful because you're not immediately pushed into a higher bracket.
