Cindy Portmann Assessor
Typically 42% - 47% of all property taxes that you pay are from voter approved levies. This includes cities, schools, parks, fire districts, and more... Read more

Washington State has a 'budget-based' property tax system, so the taxing districts budgets and voter approved measures determine how much you pay. Simply put, when values decline levy rates increase, when values increase, levy rates decrease. Learn more about levies and our property tax system

In 2012, 13 of the 16 taxing district requests to voters for funding were passed by voters.

The decrease in total residential assessed value county-wide started with the 2008 Jan. 1st assessment and reflected the decline in the market since 2007. Sales that occurred in 2012 will be used to calculate the new 2013 assessments, which will be used to calculate taxes due in 2014. Learn more about annual reports

    The Assessor's Role

The role of the Assessor's office is to establish a value for all property for tax purposes. The Assessor is required by law to set that value at 100% of market value and to assure that all values are in equalization.

The Assessor does not create market value. Market value is the price a willing buyer and seller would agree to under ordinary circumstances. This does not mean that an individual sale will automatically establish the value of a property. The Assessor uses multiple sales of comparable properties in establishing value.

Taxable property is divided into two classes. Real property includes land and all buildings, structures, and improvements to the land. Personal property includes machinery and equipment, fixtures, furniture, and other items that are movable in nature. Personal effects which are not held for sale or commercial use are not taxable.
