King County Treasury Operations provides services to King County, cities and special districts in the county, and most importantly, our residents.
The property tax team handles billing, collecting, distributing, and reporting of real and personal property taxes, gambling taxes, and local improvement district assessments.
In 2020, Treasury Operations will have billed, collected, and distributed nearly $6.3 billion in property taxes and $339 million in other assessments and fees to support the County's programs and services.
Real property with at least one year's tax that is three years past due is subject to foreclosure. In 2019, this would include accounts on which the 2016 full year tax is delinquent.
To purchase a property from tax foreclosure, a buyer must participate in the annual online auction, make the final bid, and make full payment immediately. All sales are final.
The Investment Pool performs accounting and cash management for all revenue funds and deposits for King County, cities, and special taxing districts. It also invests funds for King County and junior taxing districts, following best policies and procedures to maximize return and minimize risk for public funds, and ensures appropriate liquidity for all funds.
The investment pool balance peaked at $8.7 billion and averaged $7.3 billion in 2019.
The Debt Management section issues and administers short and long term King County debt, including such instruments as General Obligation bonds, Lease Revenue bonds, and Sewer Revenue bonds.
Proceeds support such capital activities as Harborview Medical Center, County office space, upgrading King County's technology infrastructure, solid waste, public transportation, water quality, and open space acquisitions.
