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. 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.

Read the full Overview! Please feel free to review RCW 82.14.460 and Chapter 5.49.

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.
