Level 2

I am an Alabama resident and worked three weeks in Michigan in 2018. My W-2 shows only Alabama income taxes withheld. Do I file a nonresident tax return in Michigan?

I am a full time resident of Alabama. I work for various companies that provide hospitals and other healthcare providers computer software conversion training and support when the conversion "goes live". One company that I worked for while providing training and support was in Michigan. The company provided me with a W-2 that withheld Alabama state income tax and not Michigan state income tax. Since my W-2 did not withhold Michigan income tax, do I still need to file income taxes in Michigan?
