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 that change each year based on inflation. For 2024, Arizona has five tax brackets ranging from 2.55% on the lowest incomes to 4.5% on the highest.

Your income is taxed at different rates as it moves through each bracket. If you earn $50,000 as a single filer, you do not pay 4.5% on all of it — you pay 2.55% on the first portion, then higher percentages as your income climbs into higher brackets. This means your effective tax rate (the actual percentage you pay overall) is lower than the top bracket rate.

Arizona updates these brackets and the income thresholds annually. The specific dollar amounts where each bracket begins shift year to year, so the brackets that applied in 2023 are different from 2024. When you file your return, use the brackets for the tax year you are reporting, not the current calendar year.

Key Takeaways

  • Arizona's top income tax rate is 4.5%, but most workers pay less because the state uses progressive brackets that tax different portions of income at different rates.
  • Tax brackets change every year, so you must use the brackets for the specific tax year you are filing, not the current year.
  • Your employer withholds Arizona state income tax from your paycheck based on the W-4 form you complete, and you can adjust withholding if too much or too little is being taken out.
  • Arizona offers tax credits for dependents, education expenses, and other situations that can reduce the amount of tax you owe.
  • Retirees over 62 may exclude some or all of their retirement income from Arizona taxation, depending on the source and amount.

How withholding works on your paycheck

Your employer removes Arizona state income tax from each paycheck based on information you provide on an Arizona Form W-4. This withholding is an estimate — it is meant to cover your annual tax bill so you do not owe a large amount when you file your return in April.

The amount withheld depends on your filing status, the number of dependents you claim, and any extra withholding you request. If you have a second job, a spouse who also works, or significant non-wage income, your withholding may be inaccurate. You can file a new W-4 with your employer at any time to increase or decrease the amount taken out.

When you file your Arizona return, you report all the withholding your employers took out during the year. If you withheld more than you owe, you receive a refund. If you withheld less, you owe the difference. Many people adjust their withholding in the fall if they realize they are on track to owe or overpay by a large amount.

Tax credits that reduce what you owe

Arizona offers several tax credits that directly reduce the amount of tax you owe, dollar for dollar. A credit is more valuable than a deduction because it subtracts from your tax bill itself, not just from your income.

Common Arizona credits include a dependent exemption credit (currently $2,300 per dependent for most filers), an education credit for tuition paid to Arizona schools, and a credit for property taxes or rent paid. Some credits are refundable, meaning if the credit is larger than your tax bill, you receive the excess as a refund. Others are non-refundable, so they can only reduce your tax to zero.

You must meet specific requirements to claim each credit, and the amounts phase out at higher income levels. Review the Arizona Department of Revenue website or your tax software to see which credits explore to your situation.

Special rules for retirement income

Arizona offers a significant break for retirees. If you are 62 or older, you may be able to exclude some or all of your retirement income from Arizona taxation. The rules differ depending on whether the income comes from a pension, an IRA, Social Security, or another source.

Military pensions and federal pensions are fully excluded from Arizona income tax for all retirees. Private pensions and distributions from IRAs or 401(k) plans are excluded if you are 62 or older and meet income limits. Social Security benefits are never taxed by Arizona. If you receive retirement income from multiple sources, each source may have different rules, so it is worth checking the Department of Revenue guidance or speaking with a tax preparer.

These exclusions can make a substantial difference in your tax bill. A retiree with $40,000 in pension income might owe little or no Arizona state income tax, depending on the pension source and other income.

How Arizona compares to other states

Arizona's top rate of 4.5% is moderate compared to other states. Some states have no income tax at all (Texas, Florida, Nevada), while others tax income at rates above 10%. Arizona's progressive structure means most workers pay less than the top rate.

Arizona also taxes capital gains (investment profits) at the same rates as ordinary income, unlike some states that offer preferential rates for long-term gains. If you have significant investment income, this can affect your overall tax burden.

The state also has a property tax system and sales tax, so your total state and local tax burden depends on where you live within Arizona and what you own. Maricopa County and Pima County have different property tax rates, for example.

Filing your Arizona return

Most Arizona residents file using Form 140, the standard individual income tax return. If you have business income, rental income, or other complex situations, you may need additional forms. Arizona requires you to file if your income exceeds a threshold that changes yearly — for 2024, single filers generally must file if they earned more than $14,600.

You can file online through tax software, by mail, or through a tax preparer. The Arizona Department of Revenue offers a list of free tax preparation sites if your income is below a certain level. The filing important date is April 15, the same as the federal important date.

If you owe money, you can pay online, by mail, or through an installment agreement with the Department of Revenue. If you are owed a refund, direct deposit is the fastest way to receive it — typically within two to three weeks if you file electronically.

Frequently Asked Questions

Does Arizona tax Social Security benefits?

No. Arizona does not tax Social Security benefits under any circumstances, regardless of your age or other income. This is one of the most retiree-friendly aspects of Arizona's tax code.

What if I moved to Arizona partway through the year?

You owe Arizona income tax only on income earned while you were a resident. When you file, you report your income by the month you earned it and indicate when you became an Arizona resident. You may also owe income tax to your previous state for the months you lived there.

Can I deduct federal income tax from my Arizona return?

No. Arizona does not allow a deduction for federal income tax paid. You can deduct state and local taxes (SALT) on your federal return, but not the other way around.

What happens if I do not file an Arizona return?

If you owe tax and do not file, the Department of Revenue can assess penalties and interest on top of the amount owed. If you are owed a refund, you have three years to claim it before the state keeps the money.

Are military members stationed in Arizona taxed by the state?

Active-duty military members are generally not taxed by Arizona on their military pay, even if stationed there. However, any non-military income (a spouse's wages, investment income) may still be subject to Arizona tax. The rules can be complex, so verify your situation with the Department of Revenue.
