Washington State Property Taxes

Property taxes in Washington State are limited by a number of laws that put caps on the amount homeowners can be taxed, and the amount those taxes can increase in a given year. Specifically, the total of general, non-voter approved taxes cannot be more than 1%, and the total tax levy in an area cannot increase by more than 1% in a year.

As a result of those rules, Washington State has tax rates below the national average. The state’s average effective tax rate is 0.88%, though high home values mean the median annual property tax payment is $4,158.

How the Property Tax Works in Washington State

In Washington State, taxes on real estate account for about 30% of all state and local tax revenues. Property taxes pay for local services like fire protection, public schools and parks.

Taxes on an individual property are based on two factors: the assessed value of the property and the total tax rate that applies to that property. Assessed value is determined through annually revaluations based on market data, and physical inspections that take place at least once every six years.

Tax rates apply to those assessed values. They are calculated based on the total of assessed value in a given tax district, and the total budget of a given taxing authority. So, for example, if the sum of assessed values is $500,000 and taxing authority needs revenue of $2,500, the rate would be 0.5%.

Increases in a given taxing district’s levy are limited to 1% per year or the rate of inflation, whichever is lower. Thus, if a county’s budget this year is $3,000, next year it cannot be more than $3,030. That limit does not apply to new levies, or in other special cases like annexation or new construction.

Washington State Property Tax Rates

Property tax rates in the Evergreen State can be divided into two groups: general, non-voter approved rates, and voter-approved special levies. Non-voter approved rates are used to support the ongoing functions of municipalities and counties, while voter-approved levies have specific purposes (funding a parks district, for example).

The Washington State Constitution limits the total of all non-voter approved property tax rates to 1% on a given property. Even if your county rate is 1% and your city rate is 0.75%, your total general rate will still be 1%. There is no limit on voter-approved levies, so it is common for a total rate to exceed 1%.

Tax rates in Washington State are expressed in dollars per thousand in assessed value, equal to one-tenth of a percent. The table below shows the effective tax rate for every county in Washington State, which is the amount paid annually as a percentage of overall home value.
