  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

Washington State Property Taxes

Photo credit: ©iStock.com/wwing

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 somewhat below the national average. The state’s average effective tax rate is 1.03%, though high home values mean the median annual property tax payment is almost $3,000.

If this tax structure appeals to you and you’re looking to buy or refinance property in Washington, take a look at our Washington State mortgage guide. It contains comprehensive information on mortgage rates and getting a mortgage in Washington.

A financial advisor in Washington can help you understand how homeownership fits into your overall financial goals. Financial advisors can also help with investing and financial plans, including taxes, homeownership, retirement and more, to make sure you are preparing for the future.

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.

King County

With a population of more than two million, King County is the largest county in Washington State. It stretches from the Puget Sound west to Cascade Mountains at Snoqualmie Pass. The county’s largest cities are Seattle and Bellevue.

The average effective property tax rate in King County is 0.95%. It's also the county with the state's highest median annual property tax payment at $4,254. In Seattle, the total rate is about $8.29 per $1,000 in assessed value. Rates in many King County cities have been falling as home values have been increasing. Since there is a cap on the growth in levies, steep increases in home prices are often balanced by falling rates.

If you have questions about how property taxes can affect your overall financial plans, a financial advisor in Seattle can help you out.

Pierce County

Located between the south end of Puget Sound and Mount Rainier National Park, Pierce County has the highest property tax rates in Washington State. The county’s average effective tax rate is 1.21%. Property taxes have increased in recent years, but these increases have primarily been the result of new voter-approved levies to support things like the construction of new school buildings. General levies, capped at 1% increase per year, have remained steady.

Snohomish County

Snohomish County lies directly north of Seattle and King County and contains the city of Everett. The median annual property tax in Snohomish County is $3,379, second highest in the state, and more than $1,000 above the national median.

Spokane County

Eastern Washington’s Spokane County has property tax rates well above the state average. The county’s average effective tax rate is 1.19%, slightly higher than the state average of 1.03%.

In the city of Spokane, the rate is about $11.63 per $1,000 of assessed value. That means that the taxes on a home with an assessed value of $100,000 would be about $1,163 annually, minus any exemptions or credits.

Clark County

Rank County Property Tax Rate School Rating Crimes Per 100k People

Methodology

Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
