You must pay your taxes by the date they are due to avoid penalties and interest. After the appeal period of a Board of Equalization decision has passed, changes to the assessment will be entered into the system by the Assessor’s Office and the Treasurer’s Office will notify you of adjustments made to your taxes.
Appealing to the Chelan County Board of Equalization
The Board of Equalization assists in the administration of property valuation used for tax purposes, providing an impartial forum for property owners. If a property owner disputes the assessed value of the property, the Board of Equalization will hear the owner's appeal and make an informed decision.
The board is an independent body organized to process and hear appeals of various determinations made by the County Assessor's Office. It is comprised of three citizens appointed by the Chelan County Commissioners to provide an impartial hearing environment that protects each party's due process rights and results in a fair decision.
The Board of Equalization hears and decides appeals concerning the numerous types of determinations, including; changes to real and personal property valuations; denials of senior citizen/disabled 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.
