For twenty years, states competed with each other to hand Amazon, Microsoft, and Google the most generous tax packages imaginable — free land, zero sales tax on equipment, cut-rate utility rates — in exchange for data centers that create fifteen permanent jobs and consume as much electricity as a mid-sized city. Washington State’s legislature just decided the era of that competition is over. It’s right. And every other state that hosts a server farm is watching.
The Numbers States Were Ignoring Finally Got Too Big to Ignore
Washington’s Senate Bill 6231 would eliminate the sales tax exemption on data center equipment replacement, effective July 1, 2026. The bill passed the Senate 26-23 and cleared the House Finance Committee 8-6. It generates an estimated $140 million per biennium for a state facing a significant budget shortfall. As washingtonstatestandard.com reported, the bill was requested by Governor Bob Ferguson specifically to help close that gap.
The amount being recovered is notable. Microsoft secured $333 million in sales tax exemptions for Washington data centers between 2015 and 2023 alone, according to CNBC analysis. A single Microsoft data center in Illinois received over $38 million in exemptions while creating 20 permanent jobs. Georgia — not Washington — had been projecting $327 million in data center tax waivers until someone recounted: the actual figure was $2.5 billion, a 664% underestimate. Virginia created its data center exemption in 2008, projecting it would cost $1.54 million per year. It now costs $1.6 billion annually — a 100,000% cost overrun that Virginia’s Senate Finance Chair Louise Lucas called “writing a blank check to some of the world’s most valuable corporations.”
Sixteen states have collectively granted nearly $6 billion in data center sales tax exemptions over five years, per CNBC. Many other states don’t publicly report their totals at all.
This Is Not a Local Story
At least 27 tax-related bills have been proposed across 14 states to restrict or eliminate data center exemptions, according to Bloomberg Tax reporting. Virginia’s Senate has proposed accelerating the sunset of its $1.6 billion annual exemption to January 2027. Ohio has capped future exemptions. Michigan, Georgia, Colorado, New Hampshire, and South Dakota all have active proposals under consideration.
This convergence is not coincidental. Washington’s move is the most visible because the state hosts Microsoft and Amazon — but the underlying math is the same everywhere. Data centers have been the fastest-growing source of electricity demand in the United States. AI infrastructure investment is accelerating that. States that compete to host data centres by waiving sales tax are subsidising not just the hardware, but the electricity cost increases their own residents will absorb.
Greg LeRoy, executive director of Good Jobs First, has called data centers “Exhibit A for what states should not be subsidising in 2026,” estimating states lose 52 to 91 cents per dollar through sales and use tax exemptions. Trump himself recently shifted tone, stating technology companies building data centres must “pay their own way.” Even central Washington’s Quincy — where Microsoft has operated data facilities for over 20 years and funded a new high school and hospital — now has residents concerned about long-term water availability and grid strain, as washingtonstatestandard.com has noted in its reporting on the broader Washington debate.
Big Tech Already Saw It Coming
Microsoft in January 2026 announced a five-point commitment that included pledging to not seek local subsidies, to pay utility rates that cover its full infrastructure costs, and to publish water use data per facility. The announcement was framed as corporate responsibility. It was also, unmistakably, a defensive move: by voluntarily swearing off subsidies before state legislatures could force the issue, Microsoft positioned itself as cooperating rather than being compelled.
Amazon and Google have made no equivalent commitment. Both will now face legislative pressure in multiple states simultaneously — not in the gradual, state-by-state pattern that has historically let corporations manage these fights one jurisdiction at a time, but in a coordinated wave. Washington’s bill, if it passes the full House, becomes the template that every state finance committee chair facing a budget deficit will reach for. The precedent is the product.
What This Actually Means
The data center tax holiday was always a political choice, not an economic necessity. Amazon, Microsoft, and Google built data centres in the places they built them because of land, power, fibre, and labour — not primarily because of sales tax rates on server racks. The exemptions were lobby-won sweeteners that states granted in competitive bidding wars they didn’t have to enter. The race to the bottom has no winners except the companies that triggered the race.
Washington State has calculated that $140 million per biennium is worth more to its residents than the goodwill of Microsoft’s legal team. Virginia’s Senate Finance Chair put it even more directly: the state has been subsidising trillion-dollar corporations while families struggle with housing, childcare, and healthcare costs. Fourteen other states are having the same conversation simultaneously. The era of Big Tech paying nothing for the electricity, water, and public infrastructure their server farms consume is ending — and Washington just blinked first.

Background
What is a data center sales tax exemption? Most U.S. states charge a sales tax on the purchase of equipment and machinery. States began exempting data center hardware — servers, cooling systems, networking equipment — from this tax in the early 2000s as a way to attract technology investment and the construction jobs that come with building large facilities. The exemption typically covers the initial purchase of equipment and, in some states, ongoing replacement and refurbishment. Since data centers require continuous hardware upgrades, the ongoing exemption can be worth far more than the initial incentive.
