Big Servers, Bigger Bills: The Data Center Tax Exemption Explained

Let’s be honest: when most people think about sales tax exemptions, they picture things like groceries, prescription medications, or even sales tax holidays. Not trillion-dollar tech companies building server farms the size of small cities.

And yet, here we are.

If you’ve heard any news on economic development, you’ve likely heard about data centers—the giant, humming warehouse facilities that power everything from your Netflix account to AI chatbots. What you may have missed is that these monoliths have quietly become one of the hottest sales tax exemptions in the country.

According to the National Conference of State Legislatures, 38 states currently offer data center sales tax exemptions or other tax breaks. And the price tags attached to those exemptions? Let’s just say they start with a “b”.

Whether you’re a business owner or an individual keeping up-to-date with local politics, it’s worth understanding what these exemptions are, how they work, and what the growing national backlash might mean for your state’s tax landscape.

What Exactly is a Data Center Sales Tax Exemption?

Most of the time, when a business buys equipment or supplies, it pays sales tax on those purchases. Data centers, under these exemptions, often don’t—at least not on the massive quantities of servers, cooling systems, generators, software, and (in some states) even electricity that it takes to run these facilities.

The logic behind these exemptions is this: give up some near-term tax revenue in exchange for capital investment, construction jobs, and theoretical long-term economic activity. States compete for these projects, especially when companies like Meta, Microsoft, and Amazon have billions of dollars to invest. With that type of money on the line, the bidding wars between states can get intense.

But there’s an even bigger catch. When lawmakers originally wrote these laws, most data centers were modest cloud-storage facilities. Then the AI boom arrived, and everything got a lot bigger than anyone anticipated.

A State-by-State Tour of Data Center Sales Tax Exemptions

Wisconsin Data Center Sales Tax Exemption: A $2 Billion Surprise

Wisconsin’s data cente sales tax exemption is a textbook example of where good intentions meet unexpected consequences. In the Wisconsin Legislature 2023-25 state budget, data centers were granted a sales tax exemption. This includes both the state rate of 5% and any applicable local taxes.

This exemption was approved as a way to attract economic development. However, when the budget passed in 2023, the fiscal impact was uncertain. Now the numbers are in, and they’re eye-watering. Data centers under construction in Beaver Dam, Port Washington, Mount Pleasant and Verona will cost the state an estimated $1.5 billion in sales tax revenue during construction, plus $369 million annually once the facilities are operational.

To be fair, supporters argue that the revenue was never really on the table. It’s also not the only expensive tax-free promotion on Wisconsin’s list. Grocery exemptions—which are mandated at the state and local level—cost the state about $920 million a year. Critics, meanwhile, point out that the state could do a lot with $369 million a year, such as repairing roads and providing additional school funding. The debate is very much ongoing.

Texas: The Nation’s Priciest Exemption

Everything’s bigger in Texas, including the bill for data center tax breaks.

Qualifying data centers are exempted from the state’s 6.25% sales tax on purchases related to building and maintaining the facility—including servers, hardware, software, cooling systems, emergency generators, and plumbing. An additional bonus, they’re also exempted from paying sales tax on electricity. That’s no small thing given that a single large data center can consume as much power as a mid-sized city.

Although this data center exemption has been around for a while, the numbers are vastly different. From 2014 to 2022, data centers were much smaller, and the exemption amounted to between $5 million to $30 million in lost revenue per year. By 2023, the numbers skyrocketed to more than $150 million. In 2026, Texas is looking at losing at least $1.3 billion to data center sales tax exemptions. The numbers, unsurprisingly, continue to trend upward.

The Lonestar State is projected to lose $3.2 billion in sales tax revenue over just the next two years, making it one of the most expensive tax-breaks in the United States. And the state’s Senate Finance Committee chair is concerned, calling the numbers “extremely concerning” and “unsustainable”. Legislative hearings are planned to review—and potentially repeal—the exemption.

Virginia: The Data Center Capital of the World Experiencing a Budget Crisis

If you want to see a really heated debate on data centers, look no further than Virginia, the host of more data centers than any other state or country on earth. It’s a cool headline, but a pricey one. In 2025, the state waived $1.9 billion in sales taxes from data centers alone.

That figure has sparked a full-blown legislative standoff. The Virginia Senate has proposed eliminating the exemption entirely, while the House of Delegates countered with a plan to keep it—but tied to new environmental compliance requirements.

As of early May 2026, the fight is still ongoing. Senate leaders are pushing to end the exemption as early as January 2027—eight years ahead of its scheduled 2035 sunset—while the Governor and House members favor a more measured approach, speaking positively of the revenue and jobs tied to data centers. And then, there’s the issue of honor. As House minority leader Terry Kilgore put it, “We’ve made promises to these data centers … We as Virginians need to fulfill our promises.”

Illinois’ Data Center Sales Tax Exemption: Officially On Pause

Alternatively, Illinois isn’t afraid to pull the plug on data center incentives. In a February 2026 budget address, Governor Pritzker announced a two-year suspension of state tax exemptions for new data center developments, effective July 1, 2026.

The energy angle is the crux of the story. Data centers are voracious consumers of electricity. Illinois has at least 222 data centers—fifth most in the country—and while the value of the sales tax break recently reached $1 billion annually, it’s the energy demand that is most noticeable. Consumers and other businesses are seeing higher utility bills, and recent reports warn that the centers could outstrip Illinois’ already stretched energy supply.

So while this order doesn’t cancel exemptions for existing data centers, it does pump the brakes on new ones. The tech industry, predictably, is not thrilled. The Data Center Coalition warned that suspending “this critical economic development tool would put the state at a strategic disadvantage in attracting data center projects.”

Georgia: The Math Didn’t Add Up

Georgia’s data center sales tax exemption may have the most dramatic illustration of how badly initial projections can miss the mark. The state is expected to lose $2.5 billion to data center sales tax exemptions in fiscal year 2026—664% higher than its previous estimate of $327 million.

A state audit done by the University of Georgia added a crucial detail for critics: about 70% of data center construction activity in Georgia would have occurred even without the tax exemption. Talk about rubbing salt in a wound.

Despite that, bills to sunset the exemption ahead of schedule failed to advance, leaving it in place until 2032.

The Case For (and Against) These Exemptions

Obviously, states aren’t creating these exemptions for no reason. So before you start throwing tomatoes, let’s look at the arguments on both sides.

The Arguments in Favor

Data centers bring enormous capital investment and construction activity—billions of dollars that flow through local supply chains and support thousands of construction jobs. They also generate tax revenue through other channels: income taxes from workers, property taxes, corporate taxes, and utility taxes. According to a PricewaterhouseCoopers report, that data center industry generated $3.51 billion in direct and indirect tax revenue in Illinois in 2022-2023.

States also argue—not unreasonably—that without these incentives, the investment might simply go next door. The competition between states for large-scale tech investment is fierce, and as the Data Center Coalition has argued, these facilities represent the infrastructure of the modern economy. From online purchases to telehealth appointments, the economy is shifting to a predominantly online ecosystem.

The Arguments Against

Data center construction does bring jobs, yes, but the permanent job numbers are underwhelming. A facility worth billions may employ only a few dozen full-time workers once construction is done. That’s a very different aggregate from a factory or corporate headquarters of similar scale.

Then there’s the growing energy concerns. Data centers consume enormous amounts of electricity, and the cost of building out grid infrastructure to serve them is increasingly being passed on to residential and commercial consumers.

There are also opportunity cost questions. For example, the money Texas is forgoing annually from this tax break could fund the entirety of the state’s new school voucher program, or double the size of a state disaster fund. These are trade-offs that legislatures must take into careful consideration.

Finally, there’s the polling problem. A recent poll from Quinnipiac found that 65% of Americans oppose the construction of a data center in their community. The reasons? 72% say electricity costs, 64% say water use, and 41% say noise. That level of opposition creates a tough political environment.

What This Means for Your Business

You might be thinking: “This is all very interesting, but I’m not building a data center. Why should this matter to me?” Well, there are a few reasons your business might be affected by data center exemptions.

The first? Budget pressure has ripple effects. When states lose billions in revenue from one source, they look to make it up elsewhere. That can mean narrower exemptions for other industries, higher rates, or new fees. If your business operates across multistate lines, keep an eye on how budget debates resolve. The broader tax environment could shift as a result.

Next, look at how data centers change the exemption landscape. In 2021 and 2022, 44 of the 45 data center bills introduced in states offered incentives. In 2026, only 61 of 262 data center bills covered incentives—with the vast majority focused on regulation of energy, environment, and transparency. The national mood is shifting, which could result in rollbacks on other exemptions.

Then, there’s energy costs, which are a hidden variable for everyone. If your business is a significant energy user, the strain data centers are placing on state power grids is a real operational concern.

Finally, if you sell to or supply data centers, the transactions must be closely monitored. The rules around what’s exempt and what isn’t vary significantly by state, and always apt to change. Understanding exactly what is exempt—and getting proper exemption documentation—is essential.
