King County's Mental Illness and Drug Dependency (MIDD) is a countywide 0.1% sales tax generating an about $134 million per two-year biennium, specifically for programs and services for people living with mental illness and chemical dependency. King County’s MIDD is managed and operated by the King County Department of Community and Human Services Behavioral Health and Recovery Division.

2005: The Washington State Legislature created an option for counties to raise the local sales tax by 0.1 percent to augment state funding for behavioral health services and therapeutic courts. As required by state law (Revised Code of Washington 82.14.460), revenue raised under the MIDD must be used for new and expanded mental health and substance use disorder services, including King County’s therapeutic courts.

2006: The King County Council began exploring of the possibility of utilizing the tax option in response to shrinking state investment in community-based behavioral health services and corresponding escalation in the use of jails and hospitals for people living with behavioral health conditions.

2008: After significant work in partnership with communities and the Executive, the Council authorized the sales tax levy collection to begin in 2008, with a sunset date of January 1, 2017. King County is one of 24 counties (along with one city) in Washington State that have authorized the tax revenue.

August 22, 2016: King County Council voted unanimously to extend sales tax collection for MIDD through 2025. This nine-year extension of the tax will generate an estimated $134 million per biennium (two-year budget cycle), and is known as MIDD 2.

November 14, 2016: The Service Improvement Plan for MIDD 2 was approved by King County Council.

Since its inception, King County's MIDD has been guided by adopted policy goals, as well as implementation, evaluation, and service improvement plans.

The MIDD Advisory Committee is an advisory body to the County Executive and Council on matters related to King County's MIDD. The MIDD Advisory Committee is a unique partnership of representatives from the health and human services and criminal justice communities. MIDD Advisory Committee meetings are open to the public and comments are welcome.

In November 2016, as part of biennial budget deliberations, the MIDD 2 Service Improvement Plan (SIP) was approved by the King County Council. Informed by an extensive community input process and 19 months of analysis and deliberative work by the County, stakeholders, and community members, the Service Improvement Plan is the County’s blueprint for MIDD 2. It describes a range of services and improvements planned for MIDD 2. Its appendices also include programmatic and funding recommendations and preliminary information about each of the initiatives recommended for funding.

December 2016 MIDD Partner Update

King County is beginning work with stakeholders and community members to implement the many new initiatives and improvements outlined in the MIDD 2 Service Improvement Plan, along with revising some of the existing services. Most of these design efforts are expected to occur in the first half of 2017, with new services to begin later in the year. As noted, some initiatives from MIDD 1 are being redesigned or re-envisioned and may result in re-procurement opportunities. Most initiatives from MIDD 1 will carry forward with only modest changes that will not be noticeable to service users. It is a high value for MIDD to minimize disruption and uncertainty for consumers and providers during the transition from MIDD 1 to MIDD 2 in 2017. As a follow-up to the Service Improvement Plan, King County is developing implementation and evaluation reports for Council review. They will outline steps taken to date and further work planned (especially for new and redesigned initiatives), describe how initiatives fit within MIDD 2's adopted policy goals and policy and services framework, and outline how initiatives will be evaluated. These plans will be transmitted to Council in August 2017.
