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.

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.

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