How are property tax rates determined in Washington?

Property tax rates in Washington are set by each taxing district (municipality, school district, park district, library, etc.) based on their annual levy (the amount of tax revenue they need). The rate is calculated by dividing the levy by the total assessed value of all property in the district.

What is the composite tax rate?

The composite tax rate is the sum of all overlapping taxing district rates that apply to a specific property. A typical property may be taxed by several overlapping districts. The composite rate determines your total tax bill when multiplied by your property's assessed value.

Why do tax rates vary within the same town?

Properties within the same municipality can have different composite rates because overlapping districts (school, park, fire, library) have different boundaries. A home in one school district may have a different rate than a home two blocks away in a different school district.
