No. The income of your home state is not taxable to WI. Their rules say:
- Must I file a Wisconsin income tax return?
If you are a nonresident or part-year resident of Wisconsin and your Wisconsin gross income (or the combined gross income of you and your spouse) is $2,000 or more, you must file a Form 1NPR, Nonresident and Part-Year Resident Income Tax Return. The Form 1NPR and instructions can be downloaded from our website.
Gross income means all income (before deducting expenses) reportable to Wisconsin which you received in the form of money, property, or services. It does not include items that are exempt from Wisconsin income tax, such as U.S. government interest.
Note: Even if you do not have to file, if you had Wisconsin income tax withheld from your wages or you paid estimated tax, you should file a Wisconsin return since this is the only way to get a refund.
For more detailed information see Publication 122, Tax Information for Part-Year and Nonresidents of Wisconsin. In addition, see the Form 1NPR instructions.
