Defining Arizona Residency for Tax Purposes
Like most states, Arizona treats residents and nonresidents differently for tax purposes. Understanding this distinction is critical because it could impact your state income tax liability.
Owning property or spending time in Arizona does not automatically make you a resident.
The Arizona Department of Revenue (ADOR) determines residency using “domicile” and physical presence tests.
Domicile refers to your true, fixed, and permanent home—the place you intend to return to after temporary absences. It’s more than just a physical location; it is objective evidence establishing your intent to live as an Arizona resident.
Physical presence is a secondary factor the state can use to corroborate your domicile claim. Generally, spending more than half the year (183 days) in Arizona creates a presumption of residency.
Part-time resident: You are a part-time resident if you moved to or left the state at some point during the tax year and spent a portion of it as an Arizona resident.
Nonresident: You are a nonresident if you do not meet the residency criteria and are not domiciled in Arizona. Nonresidents are only taxed on income earned from Arizona sources, such as wages, rental income, or business profits from an Arizona-based enterprise.
Who is impacted by Arizona Residency Requirements?
Arizona residency rules for tax purposes apply to the following:
- Snowbirds: If you plan to split your time between Arizona and another state, you must carefully document your domicile to avoid double taxation.
- New Residents: If you plan on moving to Arizona, you must understand how to establish residency and how it affects your tax obligations.
- Retirees: If you’re a retiree relocating to Arizona, it’s essential to understand how your retirement income will be taxed as a resident.
- Individuals with Multiple Residences: If you own properties in multiple states, you must meticulously track your time and Arizona domicile to determine your tax obligations accurately.
- Business Owners: If you own a business in Arizona, you must determine residency for personal and business tax purposes.
How to Establish Arizona Residency for Tax Purposes
If you intend to relocate to Arizona for tax purposes, you must take specific steps to establish your intent to reside as a resident.
1. Change Your Domicile
- Establish a physical residence in Arizona by leasing or purchasing a home and spending most of the year there.
- If you own homes in multiple states, you must prove that Arizona is your primary residence where you conduct your personal and financial affairs.
- Establish bank and financial services accounts in the state. Closing accounts and memberships in your previous state helps to prove your residency.
2. Obtain Arizona Identification
- Apply for an Arizona driver’s license or state identification card.
- Register your vehicle in Arizona.
- Update your voter registration to an Arizona address.
3. Update Legal and Financial Documents
- Change your address with financial institutions, insurance providers, and government agencies.
- File federal and state tax returns using your Arizona address.
- Use Arizona healthcare providers and other essential services.
4. Work and Conduct Business in Arizona
- If you work, establish Arizona as your work location.
- If you own a business, register it in Arizona and make sure it complies with state tax laws.
5. Demonstrate Intent to Remain in Arizona
- Join local organizations, participate in community activities, and engage in Arizona’s civic life.
- Keep records of your time in the state to prove residency.
How Arizona Residency Affects Taxes
Your residency status directly impacts how you file and pay state income taxes. Here’s what you need to know:
Residents
- Must file a full-year Arizona tax return (Form 140).
- Subject to Arizona’s income tax on all income, regardless of where it is earned.
- Eligible for Arizona tax deductions and credits.
Part-Year Residents
- Must file a part-year tax return (Form 140PY).
- Taxed on all income earned while a resident of Arizona, plus any Arizona-sourced income earned while a nonresident.
- May allocate income between states if moving mid-year.

Nonresidents
- Must file a nonresident tax return (Form 140NR) if they earn income from Arizona sources.
- Only taxed on income earned within Arizona, not on out-of-state income.
Important Tax Planning Considerations
- Leverage Arizona’s lower income tax rates. Arizona has a flat state income tax rate, which may be lower than other states’ rates.
- You must keep meticulous records. Track time spent in Arizona and other states and maintain documentation supporting your residency claim.
- Be careful about dual residency. Being classified as a resident in two states may result in double taxation. Work with a financial advisor to develop an appropriate strategy.
- The ADOR may request documentation to prove residency. You may be asked to provide evidence of your domicile and physical presence.
- If you maintain residences in multiple states, you may need to file tax returns in each state where you are considered a resident. This can make your tax situation more challenging.
Seek Personalized Guidance from a Financial Advisor
Navigating Arizona’s residency requirements for tax purposes can be challenging, especially if you generate income in multiple states. A financial advisor can help you:
