Ohio suspends data center tax break amid AI power cost debate

Ohio just hit the brakes on one of the most generous data center incentives in the country. Governor Mike DeWine ordered a pause on new applications for sales and use tax exemptions for data centers, a program that was supposed to cost the state $136 million but actually ran up a tab of roughly $1.5 to $1.6 billion in 2025.

That’s not a rounding error. That’s a 12-fold overshoot, the kind of budget surprise that makes state comptrollers lose sleep.

How Ohio became the AI gold rush’s favorite tax haven

The exemption was designed to lure data center developers to the Buckeye State, and on that front, it worked spectacularly. Amazon, Google, Meta, and Microsoft all piled in, collectively reporting $27.2 billion in capital expenditures tied to 2025 exemptions alone.

The 2024 figure was already eye-popping at $9.6 billion in qualifying capital investment, with the exemption costing Ohio $555 million that year.

The crypto mining angle

Ohio’s data center ecosystem has long overlapped with cryptocurrency mining, and both industries share the same fundamental appetite for cheap, abundant electricity.

A 2024 proposal from AEP Ohio, the state’s largest electric utility, sought to impose stricter terms on data centers exceeding 25 megawatts and crypto mining facilities exceeding just 1 megawatt. That proposal reflected a tension that had been building for years between energy-intensive industries and the grid infrastructure struggling to keep up with them.

DeWine’s order will not affect existing agreements. One pending tax exemption request is set for review by the Ohio Tax Credit Authority on June 1, 2026, before the pause formally kicks in.

The Ohio General Assembly’s Joint Data Center Committee will now examine the fiscal and infrastructure consequences of the data center boom.

What this means for crypto miners and investors

For publicly traded Bitcoin miners with Ohio operations or expansion plans, this development introduces a new variable into their cost models. Tax exemptions on equipment purchases can represent millions in savings annually for large-scale mining farms.

The broader signal matters more than the Ohio-specific policy. States across the country are watching the same dynamic play out: tech companies and crypto miners promise jobs and investment, receive generous incentives, then consume far more public resources than anyone budgeted for.

The $27.2 billion in capital expenditure that Ohio attracted in a single year proves the demand is real. The $1.6 billion tax bill proves the cost is real too.
