Hi, I expect to have no income earned from an AZ source in 2009. I moved to WA on January 10th and have been working here in the same job ever since.

I am living with friends until later this month when I move to an extended stay hotel.

My wife earns an AZ income and she'll move with the kids in June. We will have a rental home here in WA by July 1.

We have always filed joint returns.

Will my WA income be taxable in AZ? Do I have to take further steps to prove residency here like change auto registration, voter registration, etc?

Thank you!
