It is no secret AI giants are racing against each other to build data centers across the country. The U.S. has more than 5,400 data centers, with hyperscalers driving much of that expansion, Fortune reported.
Nobody talks about the tax breaks at the ribbon cuttings. The cameras show the shovels and the politicians. What does not make the announcement is how much revenue the state just agreed to give up, sometimes for decades, to land the project.
The Tax Break Machine Behind the Data Center Boom
The scale of the buildout is staggering on its own. The global data center sector is expected to expand at a 14% compound annual growth rate through 2030, with hyperscalers remaining the key driver of that growth. Nearly three-quarters of U.S. states now offer some form of tax incentive for data center development, covering exemptions from sales and use tax, property tax, and in some cases financial transactions tax.
The eligibility rules by state also vary. Texas requires a capital investment of at least $200 million and creation of at least 20 qualifying jobs. New York, on the other hand, has no minimum investment requirement at all, applying its exemptions across a wide range of property, services, equipment, and contracts.
The generosity of these programs stems partly from how quickly data center equipment becomes obsolete. Cloud computing hardware often needs replacing in as little as three years given the strain of AI workloads. A $5 billion data center can easily spend more than a billion dollars a year on machinery alone, making sales tax exemptions a significant factor in where companies build, Fortune reported.
Some states layer additional perks on top. Illinois offers a 20% income tax credit on wages paid to construction workers, with tax exemptions valid for up to 20 years, issued in renewable five-year increments. Minimum investment thresholds nationwide range as high as $450 million in Kentucky and as low as $2 million in parts of Maryland.
States are Losing Track of What They're Giving Up
The generosity of these programs has created a disclosure problem. Three states alone, Georgia, Virginia and Texas, report losing $1 billion or more per year to these incentives.
"No form of state spending is more out of control today than data center tax abatements," Greg LeRoy, executive director of Good Jobs First and the study's primary author, said in a news release. Illinois data center projects awarded the state's sales and use tax exemption jumped from six in 2020 to 27 by 2024, though the state stopped providing a specific revenue-loss figure estimate after fiscal 2023.
That lack of transparency has started to catch up with lawmakers. Illinois Governor JB Pritzker directed officials in June to stop processing new agreements beginning July 1, while the legislature works on stronger protections. Ohio made a similar move shortly before, pausing consideration of new requests after program costs topped $1.5 billion in a single year.
Public pushback appears to be driving much of the reversal. Rising electricity bills tied to data center power demand have made residents in several states more vocal about the tax breaks handed to some of the world's wealthiest companies, adding political pressure that simply did not exist when many of these programs were first written.
What This Means for Hyperscaler Stocks
The tax breaks matter to investors because they arrive as hyperscalers spend at a historic pace. Amazon
That spending has already shown up in stock prices. Alphabet's shares came under pressure after the company raised its 2026 capex forecast to as much as $205 billion. The reaction rippled across Amazon, Meta and Microsoft as investors' concerns about the scale of AI infrastructure spending grew.
States are not the only ones in this. The One Big Beautiful Bill Act brought back 100% bonus depreciation on qualified capital equipment. Amazon is spending $200 billion on data centers this year. That tax provision is not small for a company at that scale.
That combination of federal depreciation benefits and state-level exemptions helps explain why some analysts remain relatively unbothered by rising capex figures. TheStreet noted that the One Big Beautiful Bill Act's restoration of 100% bonus depreciation could reduce Google's taxable income and provide a cash-flow tailwind, even as its massive AI infrastructure spending raised concerns among investors.
The Road Ahead for Tax Incentives and Big Tech
Economists who have studied this disagree on how much the tax breaks actually change where projects land. The argument is that once you are building at hyperscale, the incentive is not what drives the decision. It may just tip the choice between two similar sites in the same region.
Illinois and Ohio paused. If a dozen more follow, the math on new data center projects changes. Not dramatically. But Wall Street is already nervous about $725 billion going out the door with unclear returns. Adding cost to the build does not help that conversation.
For now, the tax break era shows no sign of ending nationwide, even as a handful of states recalibrate. The bigger question, for taxpayers and shareholders alike, is whether the enormous sums flowing into data centers are producing value that justifies both the public cost and the private risk taken on to build them.
