We are retired and are snowbirds between Michigan, 6 mo and Oklahoma, 6 mo. Michigan taxes retired people less than Oklahoma. I have been an Oklahoma resident on my federal taxes. Can I change my resident status to Michigan for better tax treatment? I have been filing partial year residency in both states, allocating my income according to my time living in each state. But the questions presume that the moves are permanent and not temporary, leaving me to question if I am filing correctly. What defines my residency?
