Appeal Process

If you disagree with the new value, you have 30 days from the date on the notice of value to file an appeal with the Board of Equalization (BOE), which is a separate entity from the assessor's office. For more information and to download forms, go to Chelan County Board of Equalization.

 

Understanding Property Tax

Property tax in Washington state has been around since the establishment of the territory in 1853, and upon statehood in 1889 it was mandated in our state constitution to be applied uniformly. To assist taxpayers in learning the basics of the property tax system in our state, the Washington State Department of Revenue Property Tax Division recently created a short video (3:30 minutes) on “Understanding Property Tax.”
