Arizona State Income Tax Guide (2026)
Arizona applies a flat 2.5% income tax on all taxable income, one of the lowest flat rates in the country.
1. Arizona Flat Tax Rate
Arizona applies a single flat income tax rate of 2.5% to taxable income. Unlike progressive states, the same rate applies whether you are an entry-level worker or a high earner, which makes the calculation straightforward.
2. Deductions and Conformance
For 2026, the Arizona standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. Pre-tax 401(k) contributions, HSA contributions, and employer health premiums reduce your Arizona taxable income.
