Ohio Governor Halts New Data Center Tax Exemptions Amid Fiscal Review

COLUMBUS, Ohio — Ohio Governor Mike DeWine directed the state's Tax Credit Authority on May 27 to pause all new sales and use tax exemption requests from data centers. The move freezes a key financial incentive for the rapidly growing industry while a newly formed legislative committee evaluates its economic and infrastructural impact on the state.

The suspension follows the first meeting of the General Assembly’s Joint Data Center Committee, which was launched on May 13 to conduct a fact-finding mission into the sector. The pause is not a ban on data center construction but specifically halts the state’s consideration of new tax breaks, which have become a subject of intense debate due to their escalating cost.

This sudden pause in Ohio is a textbook example of the policy volatility businesses face when relying on long-term state tax incentives. While states compete fiercely to attract capital-intensive projects like data centers, the fiscal and infrastructure costs can quickly become political flashpoints. We see this pattern across the country: a generous incentive program is launched, investment follows, and then lawmakers are forced to reconsider when the foregone revenue dramatically exceeds projections. For any mid-sized company with significant capital expenditure plans or multi-state operations, this situation underscores the critical need for proactive tax strategy. Simply chasing the best current incentive isn't enough; you must also plan for the risk of that incentive being altered or revoked. Navigating this complex and shifting landscape is precisely where expert tax preparation and compliance guidance becomes essential.

The debate over the incentive program intensified after recent figures revealed a staggering gap between estimated and actual costs. According to reports, the tax exemption on construction materials and equipment for data centers cost Ohio $1.6 billion in lost revenue last year. This figure was more than 11 times the Ohio Department of Taxation's original 2025 fiscal year estimate of $136 million, a discrepancy that prompted alarm among lawmakers.

In his announcement, Governor DeWine acknowledged the industry's importance while supporting the legislature's review. "Data centers are a critical component to today's technology-driven economy," he stated, noting that companies previously granted the tax benefits have reported a total capital investment of $27.2 billion in 2025 alone. "As this work is ongoing, I believe it is appropriate for the Ohio Tax Credit Authority to pause its consideration of new data center tax exemptions while the full impact of data center growth in Ohio is being reviewed."

The governor's directive marks a significant policy shift. Less than a year ago, DeWine, a Republican, vetoed a legislative attempt to eliminate the same sales and use tax exemption, which was first enacted in 2013. His current decision to suspend the program reflects growing bipartisan pressure to reassess the state's approach. Some legislators are pushing for more permanent changes, including the proposed House Bill 957, which would prohibit any new data center tax exemptions.

Business advocacy groups were quick to voice their concerns. The Ohio Chamber of Commerce described the pause as a "disappointment," arguing that the data center sector is a major economic engine for the state. The Chamber cited that the industry supports 95,000 jobs in Ohio and generates a net of $1 billion annually in state and local tax revenue, warning that limiting incentives could harm the state's competitiveness in attracting technology investment.

Ohio has become one of the top five states for data center development, attracting massive projects from major technology companies. The tax incentive has been a crucial tool in securing these investments. The Ohio Tax Credit Authority will process one existing exemption request at its next scheduled meeting before the pause takes full effect, after which it will stop accepting new proposals indefinitely.

The legislative committee's study is expected to cover a wide range of issues, from the direct economic benefits of data centers to their substantial demand on local power grids and infrastructure. The review comes as some local communities have already issued their own moratoriums on new projects, and a potential ballot initiative is being organized to ban new data centers that exceed a 25-megawatt monthly power usage threshold.

All eyes are now on the Joint Data Center Committee as it gathers testimony and data. The committee's findings will heavily influence the future of the tax exemption program and Ohio's broader strategy for managing the growth of its digital infrastructure. The outcome could lead to a permanent repeal of the incentive, a modification with stricter requirements, or a full reinstatement.
