Gov. Mike DeWine on Wednesday suspended a key sales-tax exemption that had fueled Ohio’s emergence as one of the nation’s hottest destinations for data centers, acknowledging that the break’s cost to the state has spiraled far beyond what officials anticipated when it was enacted. The decision, announced by DeWine’s office and confirmed by spokesperson Dan Tierney, halts new eligibility for the incentive while the state reassesses its fiscal exposure, signaling a sharp turn in a state that had aggressively courted the massive computing facilities needed to train and run artificial intelligence models.
The sales-tax exemption had been a cornerstone of Ohio’s pitch to companies like OpenAI, which have poured billions into hyperscale data centers across the country. But updated financial analyses showed the break was on track to cost the state well over $1 billion annually — a figure that dwarfed original projections and drew fire from fiscal conservatives and community groups alike. “The governor looked at the numbers and decided we cannot sustain this,” Tierney said.
The suspension does not affect data centers already built or under construction that have qualified for the exemption, but it freezes any new entrants from claiming the benefit while the state weighs its options. The move comes as opposition to data centers themselves — hulking, energy-hungry complexes that consume vast amounts of electricity and water — has intensified from township boardrooms to the statehouse.
In communities across Ohio, residents have complained about constant noise, environmental degradation, and the strain on local power grids. A coalition of activists is gathering signatures to place a measure on the November midterm ballot that would permanently ban hyperscale data centers statewide. If it qualifies and passes, it would likely be the most stringent prohibition under consideration in the United States.
The Republican-controlled Legislature has taken notice. State Representative Adam Holmes is chairing a newly formed committee tasked with studying the industry’s impact on Ohio. “We have to ask what we’re giving up,” Holmes said in an interview. “Are the jobs and the investment worth the cost to our infrastructure and the disruption to our communities?” The committee is expected to hold hearings later this summer.
Ohio’s reassessment is part of a wider national debate. Other states, including Texas, Virginia, and California, have wrestled with how to balance the economic allure of AI infrastructure against the subsidies and utility costs it demands. A January report by Main Street Independent found that community pushback had stalled data center projects in multiple states, while industry lobbying in California ultimately weakened proposed regulations to a study requirement.
Vivek Ramaswamy, an Ohio-born Republican presidential candidate and tech entrepreneur, has weighed into the data center debate, though his position on the specific suspension was not immediately clear. Ramaswamy has previously called for a lighter regulatory touch on AI development.
DeWine’s suspension does not represent a permanent rollback; the governor’s office said it is reviewing the exemption’s long-term structure. But the signal to the tech industry is unmistakable: the era of blank-check incentives may be ending in a state that was among the most eager to host the physical backbone of artificial intelligence.
