Treatment Sales Tax Program

What is Treatment Sales Tax​?

Washington State law allows counties to collect a 1/10 of 1% sales tax to fund enhanced and expanded chemical dependency and mental health treatment services and for therapeutic courts. Thurston County has collected this tax since 2009.

The Treatment Sales Tax (TST) is a important local funding stream that works alongside federal and state funding such as Medicaid to meet mental health and substance use needs in Thurston County. Through reduced justice involvement, emergency room use, health care costs, and public assistance and increased earnings, TST programs save our community approximately $4 for every $1 spent.

TST is managed by the Thurston County Commissioners Office. A volunteer Advisory Committee comprised of Thurston County residents makes non-binding recommendations to the Board of County Commissioners regarding use of TST funds.

What are the goals of the Treatment Sales Tax?
  • ​Improve the quality of life for Thurston County residents with mental health, chemical dependency, or co-occurring disorders.

  • Reduce criminal justice involvement for individuals with mental and/or chemical dependency issues, including diverting from jail or reducing length of jail stays when possible and reducing recidivism.

  • Increase collaboration and coordination between and education and training to corrections, courts, law enforcement, mental health, and chemical dependency and housing services.

The Treatment Sales Tax works in alignment with Thurston Thrives strategies and emphasizes the use of evidence-based practices.
