- Tension: Indiana has granted Amazon roughly $8 billion in known data center subsidies, a package Good Jobs First calls the largest ever awarded to a single data center project in the country.
- Noise: The coverage of Indiana’s subsidy has focused on this year’s disclosure fight over what the state already lost. Less attention has gone to a structural detail that matters more: the exemption underneath all of it runs for up to 50 years.
- The Direct Message: Indiana didn’t just outbid every other state for data centers. It locked in the terms of that bid through the 2070s, before anyone knows whether the industry it’s subsidizing still needs the capacity.

Indiana’s known subsidies to Amazon Data Services total roughly $8.2 billion, according to Good Jobs First’s Subsidy Tracker — a figure the watchdog group’s analysts describe as roughly eight times larger than the next-largest data center subsidy package awarded anywhere in the country. No other state has committed anything close to that sum to a single company’s data center buildout.
The mechanism behind that number is a 2019 state law, House Enrolled Act 1405, passed before the generative AI boom that would make Indiana’s data center incentives so consequential. It gives qualifying large data centers a full sales tax exemption running as long as 50 years, alongside local property tax abatements of up to 10 years on buildings and 20 years on equipment. Indiana didn’t just win a bidding war for data centers. It wrote the winning bid into law on a timeline that outlasts the political careers of everyone who voted for it.
How the number got this large
Indiana disclosed $655 million in forgone sales and use tax revenue between 2019 and 2025, and only after sustained pressure. Good Jobs First flagged the state’s lack of transparency in an April report; the state comptroller’s office initially pushed back, arguing the losses were too small to be material, before correcting itself following further reporting by WTHR-TV in Indianapolis. More than 93 percent of that total, $611 million, went to Amazon alone in 2024 and 2025 combined.
That $655 million is the annual sales tax figure. The $8.2 billion Good Jobs First cites is the cumulative subsidy package across the life of Amazon’s Indiana projects, factoring in the value of the exemption over its full multi-decade term rather than what has been claimed so far. Ben Inskeep, an energy analyst with Citizens Action Coalition, has pointed to a single Indiana Michigan Power filing that illustrates why the long horizon matters: one 1,000-megawatt data center’s sales tax exemption on its electric bill alone would forgo an estimated $34.5 million a year, or more than $1.7 billion over 50 years, assuming electric rates never rise. That is the exemption’s cost from a single facility’s power bill, before counting the equipment exemption or any property tax abatement layered on top.
What Indiana got for it
The state’s case for the incentives is the same one every state makes: investment, construction jobs, a foothold in an industry expected to keep growing. Indiana has landed projects from Amazon, Microsoft and Google in the northern part of the state, drawn in part by a subsidy structure among the most generous in the country, and Amazon’s own investment announcements in the state run into the tens of billions of dollars.
What the state has been slower to disclose is the return on that investment measured in jobs rather than dollars invested. Indiana Michigan Power told regulators in 2024 that AI data centers coming into its service territory would generate an estimated 0.26 jobs per megawatt of power used, compared with 41 jobs per megawatt for other industries that have recently located or expanded in the state, a gap of roughly 150 to 1. Data centers are, by design, capital-intensive and staff-light once built. The subsidy structure Indiana wrote assumes the industrial-recruitment logic of factories and warehouses, applied to a category of facility that employs a small fraction of the people per dollar of exemption that logic was built around.
The bill that hasn’t arrived yet
Other states that built data center incentives around a shorter time horizon have already had to reckon with what happens when the cost outgrows the projection. Ohio suspended its exemption after the actual cost hit nearly $1.6 billion in a single year, roughly eleven times what legislators had approved. Virginia’s legislature spent months fighting over a $1.9 billion annual exemption before settling on a new electricity tax and a work group to study phasing out the underlying break. Arizona built a three-year moratorium into its own budget after the tax break’s cost drew sustained public pushback. Illinois paused its incentive program outright in July.
Indiana has done none of this. Its exemption runs on the 2019 statute’s terms, unmodified, with a 50-year clock that started before anyone could reasonably estimate what AI-scale data center investment would look like a decade in. No comparable state work group, moratorium or suspension has been proposed for Indiana’s program specifically, even as the dollar figures attached to it have become the largest in the country.
Part of the reason is that the exemption’s true cost is structurally hard to see in any single year. A 50-year sales tax exemption on equipment that gets replaced and upgraded every three to five years means the state keeps forgoing revenue on each new round of purchases for decades, long after the original jobs and investment promises have been fulfilled or abandoned. The annual disclosure fight over $655 million captures only the current year’s slice of an obligation that compounds far into the future.
The uncertainty nobody has priced in
The subsidy’s 50-year term assumes the underlying demand for the capacity it’s building holds for 50 years, an assumption the industry itself is not universally confident in. Citizens Action Coalition has flagged contract language in one Amazon filing with Indiana regulators that would let the company cut its requested power load nearly in half — from 2,400 megawatts to 1,200 — if it notifies its utility by early 2029, a hedge against exactly the kind of demand slowdown that would make a 50-year commitment look badly timed in hindsight. In the same case, the utility’s most recent earnings call showed the company’s contracted load actually growing, to 2,800 megawatts, which suggests the hedge hasn’t been triggered yet rather than that it won’t be.
None of this means Indiana’s bet is wrong. It means the state locked in the terms of that bet decades before the industry itself has finished deciding how much capacity it will actually need, and before Indiana’s own legislature has done what Ohio, Virginia, Arizona and Illinois have each done in some form this year: put a number on what happens if the growth curve underneath the subsidy doesn’t hold.
Indiana outbid every other state for data centers by a wide enough margin that the runner-up isn’t close. What the state hasn’t done yet is say, in public, what its plan is for the years when the bill for that bid comes due and the industry paying it looks different than it does today.
