How do you file taxes if you worked in Iowa and Arizona?

Answer 1

The answer will be different depending on which state you lived in and on whether you moved from one state to another.

The general principle is that income is taxable in BOTH the state where you earned it and the state where you were a resident at the time.

If, for example, you were a resident of Arizona and occasionally traveled to Iowa to do work, then you would claim all of the income earned in Iowa on an Iowa non-resident income tax return. On you Arizona full-year resident return, you would claim all of the income you earned all year in BOTH states. Then you would attach Arizona Form 309 to claim a credit for taxes paid to Iowa.

On the other hand, if you moved from Arizona to Iowa, then you would file an Arizona Part Year Resident income tax return and pay taxes to Arizona on the income you earned while living in Arizona. You would also file an Iowa Part Year Resident income tax return and pay taxes to Iowa on the income you earned while living in Iowa.
