I am a graduate student in Michigan but still consider my permanent residence to be in Ohio, as I plan to return there after graduation. I am able to just file income taxes with Ohio, as the two states have a reciprocity agreement.
My fiance just moved up to live with me in Michigan and she withholds state taxes for Michigan at her new job. We are getting married later this year.
If we want to file our taxes jointly once we are married should we both establish Michigan residency even though we plan on leaving after I graduate?
Thanks for the help!
