I am a military member. My residency is in AZ. My wife lived in AZ for 2 years and is registered to vote in AZ, before I joined and got stationed in MT. For our past few tax years I had her as a MT resident since she worked while we were there. We are now stationed in TX as of November 2016. Can i put her residency as AZ? She did not work last year in MT nor now in TX.
