In 2014, King County was the second fastest growing urban county in the nation, and a strong real estate market has driven property values steadily upward.

While many residential properties increased in value, the majority have not returned to the prerecession values of 2008.

King County property values increased 13.9 percent from $340.6 to $388.1 billion, and $5.4 billion in new construction was added in 2014. Look for the 2015 valuations in late May thru October. We encourage property owners to contact our office at 206.296.7300 or email us with questions regarding property valuations.

The Treasury’s Office, not the Assessor’s, collects property taxes on behalf of the state, cities, and taxing districts, and then distributes the revenue to local governments. Homeowners who do not pay their property taxes through a mortgage lender can pay quickly and easily online at www.kingcounty.gov/propertytax. They can also pay by check, cash, or credit card in person at King County Treasury Operations, 500 Fourth Ave, Ste 600, Seattle, Washington. A 2.35% service fee applies to credit card payments.

Payments made by check may only be accepted in person at one of the six King County Community Service Centers. For a listing of locations, business hours and contact information, visit www.kingcounty.gov/CSC.

To avoid interest and penalties, the first half of property taxes must be paid or postmarked by April 30, 2015. The second half must be paid or postmarked by October 31, 2015.
