Arizona's income tax brackets for 2024
Arizona has a progressive income tax system, meaning the rate you pay depends on how much you earn. The state uses tax brackets — ranges of income taxed at different rates. For 2024, Arizona has five tax brackets that range from 2.55% on the lowest incomes to 4.5% on the highest.
Your actual tax rate is not a single number. Instead, different portions of your income are taxed at different rates. If you earn $50,000, you do not pay 4.5% on all of it — you pay the lower rates on the first portions and only the higher rate on income above certain thresholds. This is why people sometimes say they are "in the 4.5% bracket" when they mean that is their top rate, not their overall rate.
Arizona adjusts its tax brackets each year for inflation, so the income thresholds that trigger each rate change annually. The brackets are slightly different for single filers, married couples filing jointly, and heads of household.
Key Takeaways
- Arizona's income tax rates range from 2.55% to 4.5%, and you pay different rates on different portions of your income depending on how much you earn.
- The income thresholds that determine which bracket you fall into change each year because Arizona adjusts them for inflation.
- Your filing status — single, married filing jointly, or head of household — determines which bracket table applies to your income.
- Arizona taxes wages, self-employment income, and investment income, but some types of income like Social Security benefits may be partially or fully exempt.
How Arizona's five tax brackets work
The five brackets exist so that lower earners pay a smaller percentage of their income than higher earners. For a single filer in 2024, the brackets work roughly like this: income up to a certain threshold is taxed at 2.55%, the next portion up to a higher threshold is taxed at 3.34%, and so on, until income above the top threshold is taxed at 4.5%. The exact dollar amounts change yearly.
To find your bracket, you look up your filing status and total income, then find the row that contains your income amount. That row tells you the base tax on income up to that level, plus the rate you pay on any income above it. Many people use tax software or a tax professional to calculate this, but the Arizona Department of Revenue publishes tax tables each year that show the calculation.
One important note: Arizona's top rate of 4.5% is lower than many other states. Some states have rates above 10%, so Arizona's overall tax burden on high earners is relatively modest by national standards.
What income Arizona taxes and what it does not
Arizona taxes your wages, salary, and self-employment income. It also taxes interest, dividends, and capital gains — the profit you make when you sell an investment at a higher price than you paid. If you receive rental income or income from a business you own, that is taxable in Arizona too.
Some types of income are partially or fully exempt. Social Security benefits are not taxed by Arizona, which is a significant break for retirees. Military pensions and some other government pensions also receive special treatment. If you receive income from sources outside Arizona, you may owe Arizona tax on it if you are a resident, but the rules depend on your specific situation and where the income came from.
Arizona does not tax retirement account withdrawals from traditional IRAs or 401(k)s differently than other income — they are taxed as regular income at your bracket rate. However, some states do exempt retirement income, so this is an area where Arizona differs from neighbors like Nevada (which has no income tax at all).
Filing status and how it affects your rate
Your filing status determines which bracket table you use. Single filers, married couples filing jointly, and heads of household each have different income thresholds for each bracket. Married filing jointly brackets are wider than single brackets, meaning a married couple can earn more before hitting a higher rate than a single person earning the same total income.
If you are married and file separately, you use single brackets, which usually results in a higher combined tax than filing jointly. Head of household status (for unmarried people supporting dependents) falls between single and married filing jointly in terms of bracket width.
How to find the current year's exact rates
Because Arizona adjusts brackets for inflation each year, the exact thresholds change. The Arizona Department of Revenue publishes updated tax tables and brackets every January on its website. You can search for "Arizona tax brackets 2024" (or the current year) and find the official tables there.
If you use tax software like TurboTax, H&R Block, or TaxAct, the brackets are already built in — the software calculates your Arizona tax automatically based on your income and filing status. If you work with a tax professional, they will use the current year's brackets to prepare your return.
The Arizona Department of Revenue also publishes a free instruction booklet with your tax forms each year that explains the brackets and how to use the tax tables. This booklet is available on their website and is written for people preparing their own returns.
Arizona tax versus federal income tax
Arizona income tax is separate from federal income tax. You owe both. The federal government has its own brackets and rates (which are different from Arizona's), and you calculate federal tax on your federal return. Your Arizona tax is calculated separately on your state return using Arizona's brackets.
Some people assume that because they owe federal tax, they automatically owe Arizona tax at the same rate. That is not how it works. You could owe federal tax and little or no Arizona tax, or vice versa, depending on your income level and deductions. Both the federal government and Arizona allow deductions and credits that reduce your taxable income, but the deductions and credits are not always the same.
Deductions and credits that lower your Arizona tax
Arizona allows a standard deduction — a set amount you can subtract from your income before calculating tax. The standard deduction amount depends on your filing status and age. If you are 65 or older, you get a larger standard deduction. You can also itemize deductions if they are higher than the standard deduction, though this is less common for Arizona returns than for federal returns.
Arizona also offers tax credits for certain situations. For example, there are credits for dependent children, credits for education expenses, and credits for property taxes paid. Credits are different from deductions — a credit reduces your tax dollar-for-dollar, while a deduction reduces your taxable income. A $100 credit saves you $100 in tax, but a $100 deduction saves you roughly $3 to $4 in tax depending on your bracket.
Frequently Asked Questions
Does Arizona tax retirement income differently?
Arizona does not exempt retirement account withdrawals from income tax. Withdrawals from traditional IRAs and 401(k)s are taxed as regular income at your bracket rate. However, Social Security benefits are not taxed by Arizona, which provides a significant break for many retirees. Some government pensions also receive special treatment — check with the Arizona Department of Revenue if you receive a pension.
What is Arizona's top tax rate compared to other states?
Arizona's top rate of 4.5% is lower than many states. Some states have top rates above 10%, while a few states like Nevada, Texas, and Florida have no income tax at all. Arizona's rate is moderate by national standards, though it is higher than some neighboring states.
Do I owe Arizona tax if I work in Arizona but live in another state?
Arizona taxes income earned within the state, so if you work in Arizona you generally owe Arizona tax on that income even if you live elsewhere. However, most states also tax their residents on all income regardless of where it is earned. You may owe tax to both states, though you can usually claim a credit on one state's return for taxes paid to the other to avoid double taxation.
How do I know which tax bracket I am in?
Find your total income for the year, then look up the tax table for your filing status on the Arizona Department of Revenue website. The table shows your income range and tells you the tax owed. Tax software does this automatically. If your income is close to a bracket boundary, a tax professional can help you understand the exact calculation.
Can I reduce my Arizona taxable income?
Yes, through deductions and credits. You can claim the standard deduction (a set amount based on your filing status and age) or itemize deductions if they are higher. Arizona also offers credits for dependents, education expenses, and property taxes. Reducing your taxable income lowers the amount subject to tax, which lowers your overall tax bill.
