This bill authorizes qualified counties in Washington to impose a sales and use tax specifically for funding behavioral health diversion programs aimed at preventing individuals with behavioral health needs from entering or remaining in the criminal justice system. A new section is added to chapter 82.14 RCW, allowing counties that have an approved behavioral health diversion plan to implement this tax through a resolution or ordinance. The tax rate is capped at 0.1 percent, and the proceeds must be allocated to various programs designed to divert individuals from the criminal justice system, including measures to reduce recidivism and enhance support services.

Additionally, the bill stipulates that the act will only take effect if it is enacted on or after August 1, 2025. This contingent effective date ensures that the implementation of the tax and associated programs aligns with the necessary planning and approval processes at the county level.
