TAXPAYER ASSISTANCE

Several types of tax exemptions and deferrals are available for homeowners, farmers and business owners in King County. In addition, you can get help if you have a question about your assessment or would like to file an appeal.

eAppeals

The Department of Assessments and the independent Board of Equalization are bringing online a new set of tools that will make it dramatically easier for taxpayers to see how their property compares to others we've used to set assessed values.

PROPERTY TAX ASSESSMENTS

Each year, our staff of accredited real estate appraisers value more than 660,000 residential and commercial properties throughout King County, as well as personal property used in business. Those valuations are then used to calculate the owner's property taxes for the following year.
