Q. What if I go to college, earn income, rent a townhouse, and am registered to vote in Minnesota, but my drivers license is in my "home state" of Illinois? Am I able to solely file taxes in Minnesota?
A. It depends on more info.
If you still have an abode in IL, you still have to file two state tax returns. If you are still a dependent of your parents, in IL, you still have to file two state tax returns.
College students, temporarily away at school, are still residents of their original state until they establish a permanent residency somewhere else. Registering to vote isn't enough.
