Treatment Sales Tax Program


What is the Treatment Sales Tax?

Since 2009, Thurston County has collected a 1/10 of 1 percent sales tax to provide funding for enhanced and expanded chemical dependency and mental health treatment services and for therapeutic courts, as allowed by state statute RCW 82.14.460 and Thurston County Ordinance #14138. As of 2017, the Treatment Sales Tax realizes approximately $5.3 million in revenue annually.

Treatment Sales Tax funds are used to pay for chemical dependency and mental health treatment services in the jail (including work release), for coordination and support of therapeutic courts in Thurston County, and for outpatient mental health and chemical dependency treatment services for adults and juveniles currently involved in the criminal justice system or at very high risk of criminal involvement. Services are provided by both County staff and community service providers.

Treatment Sales Tax oversight is provided by the County Board of Commissioners and an Advisory Committee comprised of community members. Services funded by the tax are required to collect data on types of services provided, number of people served and the outcomes (impacts) of the provision of those services. The Board of County Commissioners receives valuable information regarding community needs, suggested uses for Treatment Sales Tax (TST) revenues and the effectiveness of TST-funded services.
