Arizona Income Tax Overview
Arizona has a flat income tax rate of 2.5%. Every dollar of taxable income is taxed at the same rate, which makes calculating your state taxes straightforward. Combined with the progressive federal bracket system, your total effective rate depends on your income level.
The standard deduction in Arizona is $14,600 for single filers and $29,200 for married filing jointly. This reduces your taxable income before the flat rate is applied.
