Arizona Tax Overview for 1099 Workers

Arizona switched to a flat 2.5% income tax rate — one of the lowest flat rates in the country. Before 2023, Arizona had a multi-bracket system with rates up to 4.5%; the flat rate cut was significant for higher earners. At 2.5%, Arizona workers keep considerably more of their income than in neighboring California (up to 13.3%) or New Mexico (up to 5.9%). No Arizona city charges a local income tax, so your take-home is consistent across Phoenix, Tucson, Scottsdale, and every other city. Arizona's standard deduction of $8,350 for single filers is lower than the federal standard deduction, meaning slightly more income is taxable at the state level. Compared to the national average effective state income tax rate of roughly 4-5%, Arizona's 2.5% flat rate puts most workers well ahead.
