Arizona Income Tax Calculator
Arizona income tax is calculated on your taxable income after deductions and exemptions. This calculator estimates your Arizona state income tax liability for the current tax year. Enter your annual gross income, choose your filing status (single, married filing jointly, married filing separately, or head of household), and add any pre-tax deductions to see your estimated state tax, effective tax rate, and marginal bracket. Results update in real time as you adjust your inputs. The calculator covers Arizona state income tax only; federal income tax, FICA payroll taxes, and any local income taxes your city or county imposes are separate. All rates and brackets are sourced directly from Arizona Department of Revenue and are verified for the current tax year. Use this tool alongside the federal income tax calculator to see your combined total tax liability. Effective rate and marginal rate are both shown so you can evaluate the impact of additional income, filing status changes, or increased pre-tax contributions to a 401(k) or similar plan.

How Arizona income tax works
Arizona taxes all individual taxable income at a single flat rate of 2.5%, effective January 1, 2023 under Arizona Proposition 132 (2022), which codified the flat tax and constitutionally blocked any graduated income surtax. The rate is set in ARS §43-1011. Arizona taxable income is federal adjusted gross income minus Arizona-specific additions and subtractions, further reduced by the standard or itemized deduction.

taxable income = gross income - standard deduction
state income tax = taxable income x flat rate / 100
effective rate = state income tax / gross income x 100

Proposition 208 (2020) proposed adding a 3.5% surtax on high incomes (above $250,000 for single filers and $500,000 for joint filers) to fund education. Courts blocked implementation pending challenges, and Arizona voters subsequently passed Proposition 132 in 2022, which requires any future income tax increase to be approved by a 60% legislative supermajority, effectively preventing the Prop 208 surtax. The current flat rate of 2.5% reflects the consolidated rate that replaced the previous graduated schedule.
