Q. If I'm just visiting family temporarily for a few weeks and working remotely, am I required to file taxes as a non-resident and pay AZ income tax?
A. Yes, but "nobody" does. See http://money.cnn.com/2013/06/28/pf/taxes/business-traveler-tax-threat/ If you live in a state without an income tax (e.g. FL or TX), it’s more likely you should file in the work states. You can't use the "it all comes out even" rationale for not filing.
Q. Would I still have to do this even if the 60 day exemption applied?
A. Yes. The 60 day rule is only about whether the employer has to do withholding. You are still required to pay tax for fewer days.
