Arizona’s state income tax rate is one of the simplest in the country for individuals with a flat rate of 2.5%. This fixed rate began in the 2023 tax year and replaces the state’s former tax bracket system. This means that all individual taxpayers—no matter how much money they make—pay the same state tax percentage.
If you live in Arizona or earn income in The Grand Canyon State, filing taxes this year is more predictable than in states with a tax bracket system. For example, California has several tax rates for income earners, with some reaching double digits for top earners. In Arizona, you don’t have to worry about any of that.
Let’s take a look at what you can expect when filing taxes in Arizona for the 2024 tax season (the taxes you’ll file in 2025).
*Note that you are still responsible for Federal taxes if you meet the IRS income filing threshold. This article addresses state-specific taxes only.

Anyone who makes money in Arizona may need to file a state income tax return. It all depends on things like your adjusted gross income (AGI), filing status, and residency status.
Gross income, which includes all the money you earn before deductions—such as wages, tips, interest, and rental income—is the starting point for calculating your AGI. Arizona residents, part-year residents, and even nonresidents may need to file taxes if their AGI is above a certain threshold.
For the 2024 tax year, your AGI and tax filing status determines whether you meet the gross income limits for filing. Filers with a gross income above the fixed amount must submit an Arizona return. Nonresidents or part-year residents must also file if they exceed the income limit.
How Arizona residency impacts tax filing
Arizona has three residency statuses for tax purposes:
- Resident
- Part-year resident
- Nonresident
Your residency status determines how Arizona taxes money you earn. Whether you live in Arizona full-time or only earn income from the state, knowing your residency status is important for your taxes.
The following table explains each residency status, who qualifies, and how Arizona taxes income for each group:
| Residency status | Definition | How Arizona taxes income |
| Resident | You lived in Arizona for the entire tax year, or Arizona is your permanent home. | Arizona taxes all income no matter where it is earned. |
| Part-year resident | You lived in Arizona for part of the tax year but established residency or moved in or out of state. | Arizona taxes income earned while you were a resident, as well as any Arizona-sourced income. |
| Nonresident | You lived outside Arizona during the tax year but earned income from Arizona sources. | Arizona only taxes income earned from Arizona sources. |

Other Arizona income tax rate considerations
Arizona residents may need to know how the state taxes different types of income outside money earned from standard wages and salaries from work. This could include money from retirement, investments, Social Security, or military pay.
Let’s break down the rules for each of these categories and explore any available tax breaks:
- Retirement and pension income tax: Arizona applies its flat 2.5% income tax rate to most retirement income from sources like 401(k)s, 403(b)s, IRAs, and pension income. There are exemptions up to $2,500 for certain US government civil service pensions and Arizona state or local government pensions.
- Investment income tax: Investment income, including dividends and interest, is subject to the flat 2.5% Arizona state income tax. However, you are allowed to subtract 25% of your long-term capital gains income, which effectively reduces the long-term capital gains rate to 1.875%.
- Social Security income tax: Arizona does not tax Social Security benefits.
- Military income tax: Arizona offers a full exemption for active-duty military pay and military retirement pay.
