SENATE BILL 5814

Passed during the 2025 Washington legislative session, Engrossed Substitute Senate Bill (ESSB 5814) added new business activities to the definition of retail sales. We continue to meet with stakeholders in Olympia to better understand the bill and its implications on creative businesses in Washington State.

What is ESSB 5814?

From the Washington State Department of Revenue’s website, Engrossed Substitute Senate Bill (ESSB) 5814 added new business activities to the definition of retail sales. As of October 1, 2025, sellers must begin collecting sales tax on these services:

  • Information technology services.

  • Custom website development services.

  • Investigation, security, and armored car services.

  • Temporary staffing services.

  • Advertising services.

  • Live presentations.

  • Sales of custom software and customization of prewritten software.

We will continue to update you as we learn more. If you would like to share with us how this may impact your business, we’d love to hear from you so we can share that with legislators and other stakeholders when we meet with them.
