If you are a nonresident service member stationed in Arizona, you do not pay the vehicle license tax portion of your annual Arizona vehicle registration. If you are then reassigned overseas from an Arizona duty station and your spouse or dependent stays in Arizona, the exemption keeps applying.
Claim the exemption at Arizona MVD when you register the vehicle, with an affidavit for vehicle license tax exemption of nonresident service personnel certified by your commanding officer or a military Leave and Earnings Statement.
The commanding officer’s certified affidavit or your Leave and Earnings Statement, proof you passed any required emissions test, and payment of the other registration fees.
