MIDD Renewal

In July 2026, King County Executive Girmay Zahilay transmitted an Implementation Plan and new name for the MIDD Behavioral Health Sales Tax. The legislation reflects extensive community engagement, modernizes one of King County’s most important behavioral health investments, and renames it the King County Behavioral Health Bridge. If approved by the King County Council this fall, the plan would guide investments from 2028 through 2034.

About King County's Behavioral Health Sales Tax

The King County Behavioral Health Bridge is a countywide 0.1% sales tax that generates about $180 million per biennium. Historically, it serves over 20,000 people each year through its funding of programs and services for people living with or at risk of developing behavioral health conditions. The Bridge is managed and operated by the King County Department of Community and Human Services' (DCHS) Behavioral Health and Recovery Division (BHRD).

Previously known as the MIDD Behavioral Health Sales Tax, it has funded high-quality programs and services that, collectively, work to reduce reliance on jails, emergency rooms, and hospitals, and create connections to the community for King County residents most in need.

What to Expect—Renewal Timeline

In 2025, the King County Council approved a proposed ordinance to extend MIDD for an additional nine years through 2034.  After a two-year community engagement and planning process, DCHS prepared a new Implementation Plan that the Executive transmitted to Council in July 2026. DCHS’s Behavioral Health & Recovery Division will begin procuring programs in 2027 that will be launched the following year. These dates are subject to change. 

Community Engagement (July 2024-October 2025)
