After

Effective October 1, 2025, ESSB 5814 narrowed this general treatment by enumerating specific services as retail sales under RCW 82.04.050 — information technology services, custom website development, investigation/security/armored car services, temporary staffing, advertising, live presentations, and custom software/customization. Those enumerated services are now subject to retail sales/use tax and retailing B&O; other personal and professional services remain service & other activities B&O only. Confirm the specific service against ESSB 5814 and DOR's interim guidance.
