Arizona tax guide
Arizona transitioned to a streamlined, flat tax system in recent years, solidifying a 2.50% rate for all taxpayers. This shift from a progressive structure significantly simplifies the filing process and enhances predictability for household budgeting. By maintaining this low flat rate, Arizona aims to remain economically competitive within the Southwest region.
Key tax highlights
Payroll
- Arizona utilizes a flat income tax rate of 2.50% applied to all taxable income.
- The 2.50% rate was fully implemented following a shift from the previous progressive tax structure.
- Employers are required to withhold Arizona state income tax at a percentage rate selected by the employee, based on the flat tax structure.
Local taxes
- Arizona does not levy a local or city-level income tax, meaning your total state tax liability is limited to the 2.50% flat rate.
- While income taxes are state-only, residents should remain aware of local transaction privilege taxes (sales tax) which can vary significantly by municipality.
Deductions
- Arizona allows for a standard deduction that aligns with federal changes, reducing the amount of income subject to the 2.50% flat rate.
- Taxpayers can choose between the standard deduction or itemized deductions, provided they match their federal filing choice.

Filing guidance
Arizona residents must file Form 140 to report state income. Since the state tax is a flat 2.50%, the math is straightforward: apply the rate to your Arizona taxable income, which starts with your federal adjusted gross income adjusted for state-specific subtractions and additions. Ensure you account for any tax credits claimed during the year, as these are deducted from your total calculated tax rather than your taxable income.
