The Wisconsin Tax Appeals Commission is an independent state agency that was created by the Wisconsin State Legislature to hear and determine disputes between taxpayers and the Wisconsin Departments of Revenue and Transportation. The Wisconsin Tax Appeals Commission also resolves tax disputes in the areas of individual income, corporate income, county sales tax, cigarette use, homestead credit, and many more.
The TAC is an independent state agency that hears and decides disputes between the Department of Revenue(and, in a very limited way, the Department of Transportation) and individual taxpayers and entities. The Commission may conduct an evidentiary hearing or may act on a legal motion of a party (such as a motion for summary judgment). Beginning with 1999 cases, the decisions and select rulings of the Wisconsin Tax Appeals Commission (TAC) have been placed Wisbar.org for the benefit of attorneys and the general public. As of June 16, 2021, wisbar.org stopped uploading new decisions, and as of June, 2026, all decisions and select rulings were removed and can instead be found at
