Island County Board of Equalization

The Board of Equalization is wholly separate and apart from the Assessor’s Office. The Board of Equalization hears appeals of property value determinations made by the Assessor's Office.  They are 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. 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 only way to appeal an assessor’s valuation of your property is by timely filing a complete appeal petition with the Island County Board of Equalization.

There is no fee charged for filing an appeal. The appeal petition form must be used. A letter or phone call is not acceptable as a substitute for the petition form.

Who May File an Appeal?

A property owner or “taxpayer” may appeal. Taxpayer means the person or entity whose name and address appears on the assessment rolls, or their duly authorized agent.

Where Can I Get an Appeal Form?

Appeal forms are available on this website (click on the form below), from the Clerk of the Board at the  Island County Board of Equalization Office 360-679-7379, BOE@islandcountywa.gov or at the Camano Island office.
