Yes, you will have to prepare a tax return for both Wisconsin and Minnesota.
- The Wisconsin tax return is because you worked in the state.
- The Minnesota tax return is because that is where you are a resident.
- All states that have income tax's, require residents to fill out a tax return with all of there income. Even if it is earned in another state.
