About the Island County Board of Equalization

The Island County Board of Equalization, or BOE, is an independent body organized to adjudicate appeals of various determinations from the County Assessor’s Office.  The Board hears and decides appeals including: changes to real and personal property valuations; denials of senior citizen/disabled persons exemptions; denials of home improvement exemptions; decisions regarding historic property; forest land classification determinations; current use determinations; destroyed property determinations; and claims for either real or personal property tax exemptions.

The BOE is comprised of County residents appointed by the Island County board of Commissioners. Board members are selected for their knowledge of real estate values and each member is required by law to attend an intensive two day course on the valuation of real property. The Board's goal is to provide an impartial hearing environment that protects each party's due process rights and results in a fair decision. 

Board members receive a stipend while they are in session and receive yearly continuing education from the Washington State Department of Revenue. The Board is directed by state law (Revised Code of Washington, RCW, and Washington Administrative Code, WAC). 


How Can I Appeal the Assessed Valuation of My Property?

The Assessor's Office mails your Official Property Value Notice, or Notice of Value annually.  Taxpayers who believe the assessed value of their property exceeds its fair market value may file a petition form to appeal their valuation during the 30 calendar day period following the mailing date printed on their property’s  Notice of Value.  

Petitions must either be postmarked, hand delivered to the BOE’s office, or filed by the latter of July 1st of the assessment year OR within 30 calendar from the mailing date printed on the value notice (or other notice of determination) {WAC 458-14-056(2) and WAC 458-14-056(4)}
