The MIDD Behavioral Health Sales Tax Fund helps King County residents get well and stay well, connect to community, and thrive in recovery. Generated by a countywide 0.1% sales tax, it is our shared investment in wellness for people across King County.

In 2021, MIDD supported high-quality programs and services to address mental health, substance use, and other behavioral health conditions for those most in need. MIDD funding supports equitable opportunities for improved health and wellness, connection to community, and recovery, especially for people most affected by inequities related to race, income, and access to health care.
