Services newly subject to retail sales tax

Engrossed Substitute Senate Bill (ESSB) 5814 added new business activities to the definition of retail sales. This means sellers must begin collecting sales tax on these services on October 1, 2025:

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.
Modification of digital automated services (DAS) exclusions.

This page provides basic information on the services that are now subject to sales tax. The department will publish additional guidance in the form of Special Notices, Frequently Asked Questions, Interim Guidance Statements (IGS), Excise Tax Advisories, and Rulemaking.

We will update this page with links to the additional guidance as it’s published.

Steps we’re taking

The department is devoting significant resources to developing and publishing guidance prior to the effective date of October 1, 2025.

Current plans include:

Multiple listening sessions to be held during the month of July.
Multiple interim guidance statements (IGSs).
- We are using IGS because they are faster than administrative procedures act (APA) guidance. Our plan is to incorporate your feedback into the IGSs, which will later be converted to APA guidance.
Multiple special notices.
Multiple updates to existing web content.
Direct messages to impacted businesses with links to the published guidance.

Our goal is to publish the interim guidance in early September. However, this goal could be extended if there are unanticipated complications.

Your voice matters

Listening sessions

Due to high demand and limited capacity, registration is currently full. We still welcome your input through our online feedback survey, which is open to all and designed to capture the same types of feedback we’ll be gathering during the sessions.

ESSB 5814 Feedback survey

Feedback from the survey and listening sessions will be compiled and published as a summary report in early August.

This feedback will help inform our Interim Guidance Statements that will be published in September.

Stay informed

Other ways to provide feedback

The department welcomes your questions and feedback, including areas where you believe guidance may be needed. Your questions and feedback will help us update guidance on a timelier basis.

You can submit questions and comments to Rulings@dor.wa.gov. We will answer your questions as quickly as possible.
