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. Click Here to learn more about levies and our property tax system. In 2010, 33 of the 44 taxing district requests to voters for funding was 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 in 2007.

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. |
