Ohio just found out its data center tax break has a $2 billion hole in it

Ohio lawmakers were ready to rein in one of Big Tech’s richest tax breaks in the state. Then, late Wednesday night, they pulled the vote. The package would have reduced future sales tax exemptions for data centers, but the current deal now stays alive.

That matters because the tax break cost Ohio and local governments about $2 billion in 2025. That includes nearly $1.6 billion in state sales taxes and another $446 million in local sales taxes. A year earlier, the combined figure was about $722 million. That is not a program getting a little expensive. That is the bill jumping off the table.

Lawmakers finally saw the size of the tab

The funny part, or maybe the scary part, is that lawmakers say they did not know the tax break had gotten this big. After the number came out, a joint committee spent more than 18 hours hearing from state officials, local leaders, unions, industry groups, and residents.

The mood was not exactly friendly. Data centers are becoming harder to defend because the benefits are no longer as obvious as the costs. The old pitch was simple: give companies a break, win huge construction projects, and call it economic development. But these projects need land, power, water, fiber, and public patience. Once they are running, they do not employ armies of people.

That makes the deal feel different when the companies on the other side are Google, Meta, Amazon, and the rest of the AI machine. These are not tiny startups eating ramen in a garage. They are some of the richest companies in the world, asking Ohio to keep picking up part of the check.

The old deals were already protected

The bill that died Wednesday would not have touched existing tax breaks. It only would have reduced future ones. So even the compromise version left the biggest old deals alone.

Newly released state data shows that exemptions for Google, Meta, and Amazon could be worth about $600 million by the time their 40-year agreements mature. Across 18 companies, Ohio has agreed to at least $2.3 billion in state sales tax exemptions, and officials warned the real number could be much higher.

And that is only the state sales tax side. Many data centers also get local property tax abatements. In New Albany, one of Ohio’s biggest data center hubs, 17 data centers have received property tax abatements between 65% and 100% over 15 years. So when people talk about “the tax break,” they are really talking about a stack of breaks. It is not one coupon. It is the whole Sunday insert.

Then the vote vanished

House Speaker Matt Huffman said Senate leaders pulled the vote because House Republicans wanted to eliminate the data center tax breaks, not just reduce them. Maybe that is true. But the harder problem was vote math.

Gov. Mike DeWine already vetoed an effort last year to end the sales tax exemption. He argued the credit helps Ohio compete for data center projects and the billions in construction spending that come with them. To override him, lawmakers needed 60 votes in the House. They did not have them.

So the bill died the way expensive fights often die. No big speech. No clean ending. Just a vote that disappeared around 10 p.m., while the industry kept the deal it already had.

This is the local bill for the AI boom

The national AI story sounds shiny. Chips, models, compute, agents, and whatever word is getting investors excited this month. But locally, the AI boom looks more like tax abatements, power demand, zoning fights, water questions, and residents wondering what they are getting back.

That does not mean every data center is bad. It means the math is finally getting audited. Ohio wants the AI economy, and that makes sense. Most states do. But when a tax break jumps from $722 million to $2 billion in one year, the old sales pitch starts to sound thin.

For now, Big Tech kept the break. But Ohio lawmakers accidentally did something useful. They showed everyone the receipt.
