Probably not. Did you work in AZ? Being away from home for school is considered a temporary absence. If you intend on going ''home'' to CA after finishing school, you are a non-resident of AZ. In that case, you only have to file AZ if you have AZ sourced income? Did you or do you work in AZ? If so, file a nonresident return for AZ and your resident tax return for CA. Sounds like you are a full year resident of CA - add AZ to the Other State Income box if you have any income from AZ.
