King County Property Tax — Frequently Asked Questions
King County property taxes can increase because your assessed value rose, a levy lid lift or bond passed, the county or a district used banked capacity, or new levies were added. Washington’s RCW 84.55 limits regular levies to 1% per year per district — but with 20+ overlapping districts on a typical King bill, combined increases can be much higher. Search your address above to see every levy on your parcel, year by year.
Your King County property tax equals your parcel’s taxable value divided by 1,000, multiplied by the consolidated levy rate for your Tax Code Area (TCA). The rate is the sum of all individual levies — state school, county general, city/town, school M&O, fire district, EMS, library, port, and any voter-approved bonds — that apply to your specific location.
Use the search box at the top of this page. Enter your street address (abbreviated: “Dr” not “Drive”, “St” not “Street”) or your King parcel ID. Real Record shows your 2026 bill broken down by every levy line. Free, no login required.
King County property taxes are split among many districts: the state, the county general fund, the city or town you live in, K–12 schools, fire and EMS, parks, library, and special districts in your area. Each levy line on your bill funds a specific government service. Click any year row in the search results to see the full per-agency breakdown.
There is no single King County rate — the consolidated rate varies by Tax Code Area (your specific location within the county). In 2026, consolidated rates in King typically range from roughly $7 to $15 per $1,000 of assessed value, depending on which city, school district, and special districts cover your parcel. Search your address above to see your exact rate.
King County property taxes are recalculated every year. Assessed values are updated annually by the King County Assessor. Individual levy rates also shift each year based on district budgets, voter-approved lid lifts, and statutory limits under RCW 84.55. Your bill can change even if your assessed value stays flat, because rates shift when a levy is added, lifted, or expires.
