Tax residency

Arizona — nine-month presumption calculator

Arizona presumes residence after more than nine months in the state during the tax year, unless the presumption is rebutted. Domicile or a stay for other than a temporary or transitory purpose can establish residence earlier.

How this count works

Counts recorded dates in Arizona during the calendar year, including part days. US days recorded without a state are not counted.

More than nine months in Arizona creates a residence presumption that can be challenged. A fixed number of days is only an approximate reminder for nine calendar months. Residence can arise with fewer days based on the other applicable rules.
