@pbrabandt , since California and MI do not have reciprocity agreement and since you are CA resident, you file MI return showing the amount earned while in MI ( direct employment or remote working i.e. amounts sourced to MI) -- Non-resident return. Then you file your resident state return your total income for the year ( probably same as Federal income). This where you tell CA what income was earned in ( other ) different state -- allocate. California now will give you credit for taxes paid on that income.
Does this answer your query ?
