I am a NY resident and my employer is in NY. In 2020 I worked remotely from a family member’s home in Michigan for several months, due to the Covid pandemic. My permanent address is still in NY and I plan to return there in a couple months. I plan to file in NY as a full time resident, but do I also need to file a nonresident return in MI for the portion of income I earned while working remotely there? I do not have MI on my W-2 or withholdings as my permanent address hasn’t changed. I have been told I don’t need to file in MI as the source of my income wasn’t from MI, but from NY. I’m not sure if this is accurate since I was physically in MI doing the work. If I do have to file in MI will this result in double taxation? I am not sure if NY would grant me a resident credit for the MI taxes as NY might claim all my income is NY sourced, due to the convenience of the employer rule.
