2017 Property Taxes

Initiatives approved by voters last year will increase King County property taxes in 2017, which will result in additional investments in schools, fire protection and transportation. The majority of property tax revenue – nearly 52 percent – will pay for schools.

King County Treasury collects property taxes on behalf of the state, cities, and taxing districts, and then distributes the revenue to local governments. King County property tax bills will be mailed Feb. 10.

In some parts of King County, as much as 50 percent of 2016 property taxes are a result of voter-approved measures. These are typically school, fire, and other levies or bonds. New levies and fees approved in 2015 include:

  • Sound Transit 3 (ST3), which will connect the region’s cities with mass transit including 62 new miles of light rail; bus rapid transit on the north, east and south of Lake Washington; expanded passenger capacity on Sounder south line trains; and parking, bike and pedestrian access improvements at stations throughout the system.

  • School levies in the Auburn, Federal Way, Tukwila, Seattle, Renton, Mercer Island, Kent, Vashon Island, Lake Washington, and Highline school districts.

  • Renewal of the Low-Income Housing levy in Seattle.

  • Public safety levies in Normandy Park, Snoqualmie, and Shoreline.

  • Surface Water Management (SWM) Fee to protect water quality from polluted stormwater runoff.

While individual property taxes vary depending upon location, property taxes went up 7.96% percent at the aggregate level. Countywide, property tax billings will be $4.8 billion in 2017, up from $4.5 billion from last year. It’s the primary funding source for schools, public safety, parks and libraries.
