Arizona State Tax for Expats: Domicile, Nine-Month Presumption, and Source Income
Arizona taxes residents on worldwide income but is not generally considered a sticky state. Learn domicile rules, the nine-month presumption, and source income for Americans abroad.
Residency Persistence
Arizona taxes residents on worldwide income. An individual is an Arizona resident if in Arizona for other than a temporary or transitory purpose, or domiciled in Arizona but outside for a temporary or transitory purpose. Spending more than nine months in Arizona creates a rebuttable presumption of residency.

Special Considerations for Expats
Arizona is not generally considered a sticky state, but residency still depends on domicile.

Arizona allows a credit for taxes paid to another country on income also taxed by Arizona.
Arizona-source income, including rental and business income, can remain taxable after a move.
How Arizona Analyzes Domicile and Residency
Arizona residency analysis should separate domicile and temporary presence.
A retained Arizona home and more than nine months in Arizona can create a presumption of residency.
Arizona's foreign-income and credit rules should be reviewed separately from federal results.
Departure-year returns should allocate resident-period worldwide income and post-move Arizona-source income.
