- Tension: In the two weeks before Arizona’s data center tax moratorium took effect, developers filed nearly as many exemption applications as the state had received in the program’s entire 13-year history.
- Noise: Coverage has centered on the political fight between Gov. Katie Hobbs and Republican lawmakers over the moratorium itself, obscuring what the industry actually did the moment it knew the exemption’s clock was running out.
- The Direct Message: A three-year pause built to slow a subsidy program produced, in its final two weeks, close to a decade’s worth of new claims on it.

Between June 15 and June 30, 2026, the Arizona Commerce Authority received 113 applications for a sales tax exemption that state lawmakers had just voted to freeze. In the nearly 13 years before that, from the program’s August 2013 launch through June 14, the agency had received 123 applications total, according to Axios Phoenix. A policy designed to pump the brakes on new tax breaks for data centers instead triggered a stampede to grab the last ones available.
The moratorium goes into effect regardless. What the surge changes is how much of the program’s remaining capacity gets claimed before the freeze actually bites.
The exemption, and the compromise that paused it
Arizona’s data center sales tax exemption dates to 2013, when the legislature — Hobbs among its members at the time, then a state senator — voted to exempt qualifying data center operators from transaction privilege and use taxes on equipment purchases. The program was renewed for another decade in 2021. It has helped make Arizona the seventh-largest data center market in the country, according to the Arizona Capitol Times, which cited Gov. Hobbs’s count of nearly 98 facilities operating and 86 more planned or under construction; a separate count from the industry tracker Data Center Map put the state’s total above 150, per AZFamily.
That growth ran into organized resistance in 2025, after data center proposals in Tucson, Chandler and Marana drew sustained public opposition. Hobbs responded in her 2026 State of the State address by proposing to eliminate the exemption entirely, calling it a $38 million annual handout. Republican legislative leaders rejected a full repeal outright. Senate Majority Leader John Kavanagh argued that canceling incentives already granted to existing data centers, which run five to ten years, would expose the state to litigation.
The compromise, folded into the state budget Hobbs signed in June, freezes new applications for three years: the Arizona Commerce Authority cannot accept exemption requests from July 1, 2026 through June 30, 2029. Existing recipients keep what they were promised, and companies can still build data centers in Arizona without the incentive. Hobbs framed the pause as a $57 million savings that could go toward child care, health care and food assistance, and called it, through a spokesperson, “one of the toughest new policies in the nation.”
The rush before the freeze
The Arizona Commerce Authority has 60 days to approve or deny each application it receives, meaning the 113 filings submitted in the final two weeks will still be worked through well after the moratorium is already in effect. Of the 123 applications the program received in its first 13 years, 83 were approved — a rate that, if it holds for the June surge, could add somewhere close to 90 more exemptions to a program lawmakers just voted to pause.
Dan Diorio, vice president of state policy for the Data Center Coalition, called the outcome a letdown for developers who had been planning to apply on a longer timeline and instead rushed to beat the deadline. Russell Smoldon, an Arizona lobbyist representing the same coalition, was more skeptical of what the filings actually represent. He estimated that close to half came from operators already running facilities in the state, looking to expand or add new buildings on existing sites, and that most of the rest came from landowners without confirmed tenants or firm construction plans. “I think there was a little bit of panic associated with it, wanting to make sure you got in under the wire,” Smoldon told Axios.
Christian Slater, a spokesperson for Hobbs, made a related point in the state’s defense: nobody who wasn’t already planning a data center decided to build one because the moratorium was coming. The filings reflect existing intentions accelerated into a two-week window, not new investment the freeze somehow conjured into being.
What the surge actually resolves, and what it doesn’t
Both readings can be true at once, and that is what makes the number worth taking seriously rather than dismissing as noise. If even a third of the 113 applications convert into approved exemptions, Arizona will have granted a meaningful fraction of a decade’s worth of tax breaks in the space of two weeks, at the exact moment the legislature decided the program needed a pause. The moratorium freezes the intake valve. It says nothing about what already passed through it on the way to being shut.
That is a familiar pattern in policy with a known effective date: real estate transactions cluster before tax changes, corporate filings cluster before rule changes, and here, tax exemption applications clustered before a legislative freeze that everyone in the industry could see coming for months. Deadlines invite exactly the rush they are meant to prevent, and Arizona’s three-year pause now starts with more claims on the program pending than the state anticipated when it built the pause into the budget.
Arizona in a wider retreat from data center incentives
Arizona is not acting alone. In the same weeks, Illinois Gov. J.B. Pritzker directed the state’s Department of Commerce and Economic Opportunity to pause its own data center tax incentives starting July 1, after the legislature failed to reach a comprehensive deal, according to MultiState. Ohio Gov. Mike DeWine suspended a similar exemption after its actual cost reached nearly $1.6 billion in a single year, roughly eleven times the $142 million legislators had approved. Texas Gov. Greg Abbott has directed regulators to shield residential ratepayers from data center-driven grid costs and named repeal of the state’s sales tax exemption a legislative priority for 2027, though he stopped short of a moratorium, citing Texas’s position as the country’s second-largest data center market.
What separates Arizona’s version from Ohio’s or Illinois’s is that the moratorium was negotiated, not imposed unilaterally by the governor, and it has a fixed, publicly known expiration date rather than an open-ended pause pending further study. Danny Seiden, president of the Arizona Chamber of Commerce and Industry, said he expects the exemption to return in some form, possibly before the three years are up, and warned that other states are “foaming at the mouth” to court the projects Arizona is temporarily declining to subsidize.
The parts the moratorium leaves untouched
Pausing the tax exemption does not touch the issue that drove public opposition in the first place: water and electricity use. Arizona’s Corporation Commission, not the legislature or the governor, holds exclusive constitutional authority over utility ratemaking, which means neither Hobbs nor lawmakers can order data centers to pay more for the power and water they draw. The five-member commission, currently an all-Republican supermajority, has approved large-load tariffs for major electricity users and expressed interest in requiring big consumers to bring their own generating capacity, but Commissioner Kevin Thompson has said outright that treating new data centers as simply unwelcome isn’t realistic.
Senate Minority Leader Priya Sundareshan, an environmental attorney, has pushed a bill requiring the commission to ensure large-load customers cover the full cost of the energy, fuel, generation and transmission they use, so those costs don’t land on residential bills instead. Republican leadership in the Senate has not given the bill a hearing. Sundareshan says she isn’t confident residential ratepayers are currently protected from cost shifts, and expects data to surface soon showing why.
The tax moratorium, in other words, addresses the part of the data center fight that lawmakers have the clearest authority over, and leaves the part residents complained about most — rising utility bills and water strain — largely where it was before the budget passed.
Three years from now, the Arizona Commerce Authority will have to decide, or the legislature will have to decide for it, whether to reopen an application window that closed with more people rushing through it than anyone budgeted for. Whatever number the state settles on for how much the pause actually saved will need to account for the 113 filings that got in ahead of the deadline it was built to enforce.
