Open Book/Board of Review Calendar

The Open Book/Board of Review Calendar lists the Open Book and Board of Review dates a municipality provides the Wisconsin Department of Revenue. For your convenience, it also contains local clerk and assessor contact information. There are two separate portals, one for property owners and one for municipalities.

Each municipality in Wisconsin must hold an Open Book and Board of Review (BOR) session.

Open Book and Board of Review sessions generally take place late May to mid-June; however, some may occur later.

For more information, review the Property Assessment Appeals Guide.
