According to the Arizona instructions:
An Arizona Resident is an individual who is domiciled in Arizona permanently, even if the person is out of the state temporarily. If you live in Arizona for more than nine months, you are considered an Arizona resident.
An Arizona Nonresident is every other individual. If you live in Arizona for more than nine months and are not a resident, you need to be able to prove you are not a resident (Example: Military members stationed in Arizona are not Arizona residents if their Home of Record is not Arizona.)
Arizona considers the following when determining a person's residency:
- Physical presence
- Auto registration
- Driver's license application/renewal/relinquishing
- Bank location
- Home purchase
- Payment of personal or real property tax
- State income tax payments
- Voter registration
- Consistent use of new address on records and correspondence
An Arizona Part-Year Resident is an individual who:
- Moved into Arizona with the intent of becoming a resident
- Moved out of Arizona with the intent of giving up their Arizona residency
If one spouse is a resident and the other is not, file separate returns. To do this within your account, you can file the federal return and wait for the return to be accepted. Then, change the filing status for the primary taxpayer and file a separate return for the first spouse. The second spouse will need to create a new account and file the separate state return in that account (if required to file).
Arizona is a community property state. When filing separate returns, you must include 1/2 of the Arizona source income earned by the resident spouse.
