Make sure to fill out a new updated A4 and mark box 2 for the exemption so that your employer doesn't continue to withhold AZ taxes. That is one of the things that caused so much issues in my situation. When we left AZ to TN no one told us that we needed to fill out a new A4 form to claim that exemption. So our AZ employer kept taking out the AZ tax. When we did out taxes since we were a partial year resident only the income that we earned while physically in AZ (Jan-July) was deemed earned in AZ and then what we earned now living in TN (Aug - December) but was still being withheld by our employer was fully refunded to us.
