Understanding Personal Income Tax in Wisconsin

Wisconsin's personal income tax is discussed.

If you are a resident or nonresident of Wisconsin and receive taxable income individually from property owned or business transacted in Wisconsin, you are subject to tax on net income. Therefore, if you are operating your business as an S corporation, partnership, limited liability company, or sole proprietorship, you will be subject to a personal income tax on your business income that passes through to you.
