Making temporary staffing services provided to nonprofit behavioral health entities exempt from retail sales tax.

SB 6297 exempts temporary staffing services purchased by nonprofit behavioral health entities from Washington state's retail sales tax. This directly affects nonprofits providing mental health, substance use, or similar behavioral health services that rely on temporary staff. The bill amends state tax law to exclude these specific staffing costs from taxable "retail sales," reducing operational costs for qualifying organizations. The change applies only to services used directly by the nonprofits in their behavioral health operations, not to general business expenses.
