Washington State Data Center Policy: Big Tech Wins Rate Regulations Fight But Loses Tax Break

In a dramatic conclusion to Washington State’s 2026 legislative session, major technology companies secured a significant victory by blocking sweeping regulations on data center operations, while simultaneously losing a valuable tax incentive for facility upgrades.

The Washington State Legislature adjourned Thursday night after passing a contentious measure that eliminates a sales tax exemption on equipment and labor used to refurbish existing data centers. Senate Bill 6231 preserves tax benefits for new facilities but removes them for upgrades to current infrastructure, marking a pivotal shift in the state’s approach to managing its booming data center industry.

The Tax Break Elimination: A $143 Million Impact

The legislation, which takes effect July 1, ends a tax break that has been instrumental in supporting Washington’s data center ecosystem. According to the state Department of Revenue, eliminating this exemption will generate $63.1 million in the current biennium and $143.9 million for the 2027-29 period.

“This is a self-inflicted hit to the state’s economy that will ultimately cost jobs and tax revenue,” warned Dan Diorio, vice president of state policy for the Data Center Coalition. He emphasized that the equipment inside data centers typically requires replacement every three to five years, making the tax break crucial for ongoing operations and upgrades.

The economic stakes are substantial. A 2023 PwC report commissioned by the Data Center Coalition revealed that Washington’s data centers directly employed nearly 9,000 workers while supporting an additional 39,000 indirect jobs across the state. The sector generated $1.8 billion in state and local tax revenue, underscoring its importance to Washington’s economic landscape.

The Failed Regulatory Push: House Bill 2515

While the tax break elimination represents a win for state revenue, data center operators successfully fended off far more comprehensive regulations that would have fundamentally altered how these facilities operate. House Bill 2515, which approached the legislative finish line last month, would have imposed unprecedented requirements on data center owners regarding energy usage, environmental impact, and operational transparency.

Microsoft emerged as the most vocal opponent of HB 2515, with Lauren McDonald, the company’s senior director of Washington state government affairs, testifying before a Senate committee that the company “respectfully urge[d] the committee not to advance the bill without significant changes.” McDonald characterized the legislation as “uniquely anti-competitive,” arguing it would disadvantage Washington-based facilities compared to operations in other states.

The Seattle Times reported that both Microsoft and Amazon actively lobbied for modifications to the bill, though Amazon did not provide formal testimony. Microsoft maintains an estimated 30 data centers in Washington, while Amazon has historically concentrated its Pacific Northwest data center footprint in Oregon.

What the Regulations Would Have Required

HB 2515 represented a comprehensive attempt to address growing concerns about data center impacts on Washington’s communities and resources. The legislation would have:

• Codified commitments to prevent data centers from driving up electric bills for consumers
• Required facilities to disclose their energy and water usage for cooling data center electronics
• Established requirements for clean power usage
• Mandated that data center owners share forecasts on their energy needs
• Created transparency around the environmental and ratepayer impacts of these massive facilities

The bill garnered support from environmental groups, tribal nations, and ratepayer advocates who argued that the rapid expansion of data centers—driven largely by artificial intelligence and cloud computing demands—poses significant risks to Washington’s energy grid, water resources, and community welfare.

The Broader National Context

Washington’s legislative battle reflects a nationwide reckoning with data center expansion. Across the United States, local leaders and communities are increasingly concerned about the surge in facilities that power the internet and artificial intelligence. President Trump earlier this month convened major tech companies at the White House, where they pledged not to drive up electric bills—a commitment that HB 2515 would have codified into state law.

The tension between economic development and community protection has become particularly acute as data centers require enormous amounts of electricity, water for cooling systems, and physical space. Many communities have found themselves balancing the promise of high-tech jobs and increased property tax revenue against concerns about resource consumption and infrastructure strain.

Industry Opposition and Economic Arguments

Opponents of HB 2515, including representatives from the tech sector, labor unions, and local municipalities that have benefited financially from data center operations, testified that these facilities support essential computing infrastructure and create jobs. They argued that the regulations would make Washington less competitive compared to other states actively courting data center investment.

“The data center industry has been a cornerstone of Washington’s technology sector for decades,” said one industry representative during legislative hearings. “These facilities provide the backbone for cloud computing, artificial intelligence, and the digital services that power our modern economy.”

However, supporters of the legislation countered that the industry’s rapid growth has outpaced appropriate oversight, leaving communities without adequate tools to negotiate fair terms or protect vital resources.

The Future of Data Center Regulation

Despite the defeat of HB 2515, its sponsor, Rep. Beth Doglio, D-Olympia, remains committed to the cause. “Some of the largest and most powerful corporations in the world deployed an extraordinary lobbying effort to weaken, delay, and ultimately stop this legislation,” Doglio said. “But this fight is far from over. We will continue working to ensure that data center expansion benefits all Washingtonians, not just the corporations that operate these facilities.”

The passage of SB 6231, meanwhile, signals that Washington is willing to reassess the tax incentives it offers to attract and retain data center investment. The elimination of the refurbishment tax break suggests a more nuanced approach to economic development—one that weighs the costs and benefits of these massive facilities more carefully.

Looking Ahead: Uncertainty and Opportunity

As Washington’s data center industry navigates this new regulatory landscape, uncertainty looms over how companies will respond to the loss of tax benefits for upgrades. Will they continue investing in Washington, or will they shift resources to other states with more favorable tax treatment? The answer could have significant implications for the state’s technology sector and broader economy.

For now, data center operators have successfully defended against the most comprehensive regulatory framework proposed in any state, maintaining operational flexibility while accepting the loss of certain tax advantages. The outcome represents a complex compromise between the state’s need for revenue, communities’ desire for oversight, and the tech industry’s interest in predictable operating conditions.

As artificial intelligence and cloud computing continue their explosive growth, Washington’s experience offers a preview of similar battles likely to unfold across the country as communities grapple with the profound impacts of the digital economy’s physical infrastructure.
