Q. I was just curious if there was a way I could avoid making that large payment again this year?
A. As you can tell from the discussion, it's not 100% clear cut. Don't file an IL return and hope you can explain it if questioned. You circumstances are not the typical college student. If your permanent move, this summer, is to somewhere other than IL, it helps your case.
I'm not specifically familiar with IL & MN tax rates, and/or forms, but a $500 difference seems unusual, for typical student income amounts. Carefully check the forms for accuracy.
