Welcome to the Board of Equalization
The Board of Equalization was established under Chapter 84.48 RCW. County Boards of Equalization are quasi-judicial bodies, governed by the state Department of Revenue. A Board of Equalization is completely independent of the county Assessor's office.
Boards of Equalization, consisting of three to five citizen volunteers, provide taxpayers with the opportunity to appeal property assessments, including assessments of real and personal property, forest land, timber, and open space. Boards of Equalization also consider appeals for senior citizen property tax exemption denials. Boards of Equalization are responsible for providing an impartial hearing environment,thereby protecting each party's due-process rightswhile reaching a fair decision.
The current Mason County Board of Equalization is made up of three members and one alternate member. All serve three-year terms. The members usually are from each commissioner district. Members should have some knowledge of property values, and may not be an elected official or employed by an elected official. One member is appointed each June. Appointments are made by the County Commission.
