The TST Advisory Committee’s primary role is to make non-binding recommendations to the BOCC regarding the use of TST funds. The Committee also works to identify gaps in the local behavioral health system, promote collaboration among funded programs, and review program data to support ongoing program improvement.

  • Can commit time (see below) to serve on this committee
  • Have no personal or immediate family member commitment, investment, obligation, or substantive involvement (financial or otherwise), in any agency contracting with, submitting proposals to, or expected to submit proposals to the Treatment Sales Tax fund

What is the time commitment?

Committee members are appointed by the BOCC to staggered 2-3 years terms. In 2019, the Committee will meet approximately 6-8 times for 2-3 hours. In 2020, which is a budget development year, the Committee will meet approximately 8-10 times.

​Announcement Archives


The Treatment Sales Tax (TST) is a local funding stream that works alongside federal and state funding such as Medicaid to meet mental health and substance use needs in Thurston County. Programs funded with TST aim to reduce justice involvement, emergency room use, health care costs, and public assistance.

TST is a 1/10 of 1% sales tax collected in Thurston County since 2009. In 2021, this tax generated $7.7 million in revenue. Funds are spent on a variety of services including treatment courts such as Drug Court, services at the Thurston County Correctional Facility, community programs, and programs serving youth and families.

What are the goals of the Treatment Sales Tax?

Goals Image.png

The Treatment Sales Tax program intends to:

  • ​Improve the quality of life for Thurston County residents with behavioral health needs;

  • Reduce criminal justice involvement for individuals with behavioral health needs, including jail diversion and reducing recidivism;

  • Promote collaboration, coordination, and training across funded programs: Community Programs, Behavioral Health Providers, Corrections, Treatment Courts, Housing Services, and Youth & Family Services;

How can community agencies, schools, or other jurisdictions apply for TST funding?

Every 1-2 years, Thurston County Public Health and Social Services issues a Request for Proposals (RFP) for TST funding; an example of an RFP from a prior year can be found here.

Past grantees have included treatment providers, community agencies, school districts, and local jurisdictions. The next RFP process will be in early 2021; updates and application materials will be posted to this website. Please note that the majority of TST funding is allocated to County offices and departments through the County’s biennial budget process.
