Explore the implications of Washington’s new digital ad tax and the potential for litigation in the evolving landscape of digital advertising regulations.

Introduction

The landscape of digital advertising is undergoing a significant transformation with the enactment of Washington’s new digital ad tax. Signed into law by Governor Bob Ferguson on May 20, 2025, Senate Bill (SB) 5814 marks a pivotal shift in the state’s tax policy, expanding the retail sales and use tax to encompass digital advertising services and a range of high-tech IT services. This development not only impacts businesses operating within Washington but also sets a precedent that could influence digital advertising regulations nationwide.

Understanding SB 5814: The New Digital Ad Tax

SB 5814 redefines “sale at retail” in RCW 82.04.050 to include “advertising services,” thereby broadening the scope of taxable transactions. The law specifically targets:

Online Referrals
Search Engine Marketing
Lead Generation Optimization
Web Campaign Planning
Digital Ad Placement
Website Traffic Analysis

While it covers a wide array of digital advertising activities, the legislation explicitly excludes traditional advertising mediums such as newspapers, radio and television broadcasting, and out-of-home advertising like billboards and transit signage. This selective taxation approach suggests a focus on digital over traditional advertising channels, raising questions about compliance with the federal Internet Tax Freedom Act (ITFA).

Legal Challenges on the Horizon

The enactment of SB 5814 is poised to face substantial legal scrutiny. The ITFA prohibits states from imposing taxes that discriminate against digital services when comparable offline equivalents remain exempt. By taxing digital advertising while excluding its nondigital counterparts, Washington’s law appears to be in direct conflict with ITFA provisions.

This scenario mirrors Maryland’s Digital Advertising Gross Revenues Tax, which has been entangled in litigation since its 2021 inception. A Maryland trial court identified the law as violating ITFA and federal preemption principles, and similar legal battles are expected for Washington’s tax. Businesses and industry stakeholders anticipate inevitable litigation, which could potentially overturn or modify the current legislation.

Impact on the Digital Advertising Ecosystem

The introduction of this tax introduces several challenges for the digital advertising sector:

Increased Operational Costs

Local advertisers and businesses leveraging digital marketing tools will encounter higher operational costs. These expenses are likely to be passed on to consumers, resulting in increased prices for digital products and services.

Reduced Competitiveness

Washington’s tech-driven economy may suffer from reduced competitiveness as the new tax inflates prices and complicates the financial landscape for high-tech services. This change may deter both local and international businesses from expanding their digital advertising efforts within the state.

Tax Pyramiding and Administrative Burden

SB 5814 extends the tax to high-tech services such as custom website development, IT technical support, and data processing. This extension risks tax pyramiding, where taxes accumulate at multiple stages of production and service delivery, leading to inefficiencies and increased administrative burdens for businesses.

The Future of Digital Advertising in a Regulated Environment

Despite the uncertainties surrounding SB 5814’s enforceability, its existence underscores a growing trend towards increased regulation in the digital advertising space. Businesses must prepare for a more regulated environment by:

The anticipated legal battles will play a crucial role in shaping the future of digital advertising not only in Washington but potentially across other states considering similar measures.
