Ohio Suspends Data Center Tax Breaks Amid AI Infrastructure Debate

Ohio Governor Mike DeWine has suspended a tax incentive program for new data centers, a move aimed at reassessing the state's approach to the rapidly expanding artificial intelligence industry [1]. The decision follows a significant surge in the cost of the tax break, which far exceeded initial state projections [2].

Key takeaways

• The state’s data center tax exemption reached nearly $1.6 billion in 2025, significantly higher than the $142 million originally projected for that fiscal year [1].
• Ohio’s broad tax break covers both construction materials and expensive hardware, such as cooling systems and server racks [2].
• A citizen-led initiative is currently seeking to place a referendum on the November ballot that would permanently ban the construction of hyperscale data centers in Ohio [1].
• Thirty-eight states currently offer some form of sales tax relief for data centers, according to the National Conference of State Legislatures [2].

Rising Costs and Public Scrutiny

The suspension of the tax break comes as Ohio lawmakers form a joint committee to study the economic, environmental, and security impacts of data center development [1]. While the state previously projected the exemption would cost $136 million in 2025 and $142 million in 2026, the actual utilization in 2024 was $554 million, followed by the nearly $1.6 billion figure in 2025 [2]. Governor DeWine’s office stated that the "pause" is intended to provide clarity to both citizens and businesses while the legislative research process unfolds [1].

Despite the suspension, Governor DeWine maintains that data centers are a vital component of the modern economy, noting that roughly $37 billion in related investments were expected in Ohio during 2024 and 2025 [2]. However, the industry faces mounting pressure to cover the full costs of the infrastructure required to power energy-hungry AI warehouses [1]. This tension has created friction with business groups and labor unions, such as the Columbus/Central Ohio Building and Construction Trades Council, which warned that the policy shift could cause developers to abandon planned projects or move investments to other states [2].

Why it matters

The debate over data center incentives is not limited to Ohio; similar budget negotiations have stalled in Virginia over a proposed $1.6 billion annual tax break [1]. As tech giants increase their spending on hyperscale facilities to support AI, states are grappling with the balance between attracting high-tech investment and managing the strain on local resources [2]. The future of Ohio’s tax policy remains uncertain, as the state approaches a midterm election where a potential referendum could impose a strict ban on new large-scale data center construction [1]. With Governor DeWine term-limited, the state’s long-term strategy for the "Silicon Valley" of the Ohio River Valley will likely be shaped by the next administration and the outcome of the ongoing public pushback [2].
