The MIDD Behavioral Health Tax Fund ensures that people with behavioral health needs across King County are healthy, safe, and have access to the care they need. Generated by a countywide 0.1% sales tax, it is our shared investment in wellness for people across King County.

In 2020, the pandemic’s economic downturn reduced MIDD funds available for mental health and substance use services—just as the need was rising. Despite these challenges, MIDD funding supported partners to adapt and innovate to meet the moment with resilience.
