Washington’s Expanded Definition of Digital Automated Services: What Businesses Need to Know

Washington's 2025 changes to its Digital Automated Services (DAS) rules is one of the more significant sales tax developments facing technology-enabled service providers. Today’s post walks through what changed and where things stand today.

The Human-Effort Exclusion: Why It Protected Many Services

For years, services that primarily involved human effort performed in response to a customer's request were excluded from the definition of DAS. Historically, that exclusion allowed many businesses to distinguish between taxable automated services and nontaxable professional or consulting services. If a service primarily involved human effort, it generally fell outside DAS and was reported under the service and other activities B&O classification, not retail sales tax. 

Washington Eliminated the Human-Effort Exclusion

Effective October 1, 2025, Engrossed Substitute Senate Bill 5814 repealed the human-effort exclusion (along with exclusions for advertising, live presentations, and data processing). Services that were previously protected by the exclusion may now be taxable retail sales subject to retail sales tax and the retailing B&O classification. The exclusion remains only for sales between members of an affiliated group.

The challenge is that most modern service providers rely on technology in some form. Consulting firms use proprietary software and data analytics tools. Marketing agencies utilize automated reporting platforms. Data providers aggregate and analyze information through online portals. Increasingly, businesses are incorporating artificial intelligence into their service offerings. While the technology may be critical to delivering the service, many taxpayers would argue that the true value being purchased is still the expertise, analysis, insight, or recommendations provided by people.

Washington Provides Guidance, but Questions Remain

Under the prior rules, taxpayers often focused on whether the service primarily involved human effort. If the answer was yes, the transaction generally fell outside the DAS definition. That analysis is no longer available in many situations. Washington's definition of DAS remains broad, covering electronically transferred services that use one or more software applications, making it considerably more difficult to determine where taxable technology ends and professional services begin.

What’s Clear. Washington did not leave taxpayers without a framework. In a September 12, 2025 interim guidance statement, the Department of Revenue set out a four-part test for when a professional service delivered through a digital product is not a taxable DAS. A service stays on the professional-services side of the line when all four are true:

1. The purchaser cannot use the digital product to perform the service themselves.
2. The price is known at the time of purchase and does not change based on availability of the digital product.
3. The digital product is not marketed as, or available for, separate purchase.
4. The digital product is provided without a separate charge.

What’s not. Artificial intelligence may be the clearest example of the uncertainty taxpayers now face. Consider an AI-enabled service that reviews contracts, analyzes financial data, identifies sales tax exposures, or generates business recommendations. Is the customer purchasing software? A taxable automated service? Professional consulting? Many AI-based solutions fall somewhere in the middle. Technology performs much of the work, but human professionals often review outputs, interpret results, and provide the advice that ultimately drives client decisions.

The same concerns extend beyond AI. Data analytics providers, research firms, valuation specialists, engineering firms, and accounting firms increasingly deliver services through technology platforms. Clients may access dashboards, reports, or online portals as part of the engagement. The question becomes whether those technological components are merely tools used to deliver a professional service or whether Washington will view the overall offering as a taxable DAS transaction.

Until permanent guidance is issued, businesses will be left evaluating how much weight should be given to the technological components of their services and whether those components change the character of the transaction.

What Businesses Should Do Under the Expanded DAS Rules?

Businesses delivering services through technology should reassess what they are selling, how those services are delivered, and whether they may fall within Washington's expanded DAS rules. As technology becomes embedded in nearly every service offering, distinguishing between taxable automation and nontaxable expertise may be among the toughest sales tax questions Washington taxpayers face going forward.
