This update affects residents, part-time residents, and nonresidents who earn income from Arizona sources.

Here’s a detailed breakdown of what has changed, who is affected, what actions are required, and what this means for pending and future tax filings.
Summary of What Changed
Arizona has adopted a flat state income tax rate of 2.5% for the 2025 tax year. This means that all taxable income, regardless of how much you earn or your filing status, is taxed at the same rate.

Who Is Affected by the Flat Tax Rate in Arizona?
This change affects several groups:
- Arizona Residents: Anyone who lives in Arizona for the full year and earns above the minimum income threshold must file a state income tax return and pay the 2.5% flat tax rate.
- Part-Time Residents: If you lived in Arizona for only part of the year, you must pay the 2.5% rate on all income earned while you were a resident, plus any income from Arizona sources during the rest of the year.
- Nonresidents: If you do not live in Arizona but earn income from Arizona sources (such as a job, rental property, or business), you may owe state income tax at the 2.5% rate on that income.
- Immigrants and Newcomers: Anyone who has recently moved to Arizona or is planning to move should be aware of the new flat tax rate and how it applies to their situation.
Effective Dates
- The flat tax rate of 2.5% applies to income earned in the 2024 calendar year.
- Taxpayers will report this income and pay the tax when filing their Arizona state income tax returns in 2025.
- As of July 9, 2025, there are no announced changes to this tax structure for the following year.

Background: Why Did Arizona Move to a Flat Tax Rate?
Arizona used to have a graduated income tax system, which meant that people with higher incomes paid a higher percentage in taxes. The rates ranged from 2.59% to 4.5%, depending on how much you earned. In 2023, Arizona switched to a flat tax system. The main reasons for this change were:
- Simplification: A flat tax rate makes it easier for people to understand and file their taxes.
- Attractiveness: Lower and simpler taxes can attract new residents and businesses to Arizona, especially from states with higher taxes.
- Competitiveness: Arizona wants to be seen as a tax-friendly state, which can help its economy grow.
How Does the Flat Tax Rate Work?
The flat tax rate means that everyone pays the same percentage of their taxable income, no matter how much they earn. Here’s how it works in practice:
- If you earn $20,000 in taxable income, you pay 2.5% of that amount, which is $500.
- If you earn $100,000 in taxable income, you pay 2.5% of that amount, which is $2,500.
- There are no different brackets or higher rates for higher incomes.
Who Benefits from the Flat Tax Rate?
- Higher-Income Earners: People who used to pay higher rates under the old system now pay less.
- People Moving from Other States: Arizona’s low flat tax rate makes it attractive for people thinking about moving from states with higher taxes.
- Businesses and Entrepreneurs: Lower taxes can make Arizona a better place to start or run a business.
What About Lower-Income Earners?
While the flat tax rate is lower than the highest rates under the old system, it is slightly higher than the lowest old rate. However, the income thresholds for filing are set to make sure that people with very low incomes do not have to file or pay state income tax.
Filing Requirements in Detail
To help you understand if you need to file an Arizona state income tax return, here are the income thresholds again:
- Single Filers: Must file if gross income is $14,600 or more.
- Married Filing Jointly: Must file if combined gross income is $29,200 or more.
- Head of Household: Must file if gross income is $21,900 or more.
Gross income includes all income before any deductions or exemptions. If your income is below these amounts, you generally do not need to file a state income tax return in Arizona.
Special Rules for Part-Time Residents and Nonresidents
- Part-Time Residents: If you lived in Arizona for only part of the year, you must pay the 2.5% flat tax rate on all income earned while you were a resident. For the rest of the year, you only pay Arizona tax on income from Arizona sources.
- Nonresidents: If you do not live in Arizona but earn income from Arizona sources, you must pay the 2.5% tax on that income. This includes wages from an Arizona employer, rental income from Arizona property, or business income from Arizona activities.
How to File as a Part-Time Resident or Nonresident
Arizona provides special forms for part-time residents and nonresidents. These forms help you calculate the portion of your income that is subject to Arizona state income tax. You can find these forms on the Arizona Department of Revenue website.
No Pending Changes for 2025 and Beyond
As of July 9, 2025, there are no announced changes to Arizona’s state income tax structure. The flat tax rate of 2.5% is expected to remain in place for the next tax year. This stability allows residents, newcomers, and businesses to plan ahead without worrying about sudden tax increases or complicated changes.
Why Is Arizona’s Flat Tax Rate Important for Immigrants and Newcomers?
For immigrants, newcomers, and people moving to Arizona from other states or countries, understanding state income tax rules is important for several reasons:

- Budgeting: Knowing the flat tax rate helps you plan your finances and avoid surprises at tax time.
- Business Planning: If you are starting a business or working as a contractor, the flat tax rate makes it easier to estimate your tax obligations.
How Does Arizona Compare to Other States?
Arizona’s flat tax rate of 2.5% is one of the lowest in the United States 🇺🇸. Many other states have higher rates or more complicated tax systems. For example:
- California: Has a graduated income tax system with rates up to 13.3%.
- New York: Has rates up to 10.9%.
- Texas and Florida: Do not have a state income tax, but may have higher property or sales taxes.
Arizona’s low flat tax rate makes it a popular choice for people looking to move from higher-tax states.
