All appeals will go through the County Board of Equalization. Once an appeal form and evidence packet is submitted, the County Board of Equalization will contact you or your appointed property tax consultant with a scheduled time, date, and location for the formal review hearing. During this formal review hearing, either you or your appointed property tax consultant and the county assessor will be provided with the opportunity to give a spoken statement and provide written evidence supporting any claimed value of the property to the County Board of Equalization.

Using the evidence collected prior to the hearing, you or your property tax consultants then need to present, what the board deems, a clear and convincing argument as to why the property was over assessed and that true value of the property is best reflected by this evidence. Following the hearing, the Board of Equalization will issue a decision within 45 days of the hearing.

If you wish to further contest the Board of Equalization’s decision, you can appeal to the Washington Board of Tax Appeals (BTA) as long as you file within 30 days of the Board of Equalization's postmarked decision. When taking an appeal to the BTA, you will still need to file your taxes for the county assessed amount and then need to petition the Superior Court for a refund based on the final adjusted amount.
