Gov. Maura Healey is tapping the brakes on one of Massachusetts' newest corporate sweeteners, ordering a pause on the state's data center tax incentive and freezing applications for a 20-year sales and use tax exemption. The move stalls a key piece of last year's economic development law and signals that Beacon Hill wants a closer look at how massive computing projects qualify for long-term tax breaks. For now, state officials are hitting pause while they write rules meant to shield households and towns from higher utility costs and other local fallout.
The administration is effectively shutting the door on new certifications while agencies hammer out standards on energy supply, water use and community impacts. No new facilities will be certified as "qualified data centers" until those guardrails are in place.
As reported by Boston Business Journal, Healey tied the pause to her broader Mass Wins economic package and said the hold will remain until "protections exist against higher utility bills." The moratorium specifically applies to the certification process that unlocks the 20-year exemption for projects designated as qualified data centers under the 2024 law.
"I am halting any tax incentives for data centers until we have strong protections in place for our residents and communities against higher gas and electric bills," Healey said in a statement, as reported by CBS Boston. Alongside the pause, the administration released a policy framework that officials say will guide agency reviews and set conditions that future projects will have to meet if they want the generous break.
What the tax break covered
At the center of all this is the Massachusetts Department of Revenue program known as the Qualified Data Center Sales and Use Tax Exemption. Created by the 2024 Mass Leads Act, it wipes out sales and use tax on purchases of equipment, software, electricity and eligible construction costs for a 20-year qualification period.
According to the Department of Revenue, certification hinges on meeting minimum investment and job thresholds, and the 20-year exemption window is tied to the official qualification date the state approves. In other words, once you are in, you are in for a long time.
How Healey wants data centers to operate
Healey's new framework tells developers, in effect, to "bring your own clean energy" and cover 100 percent of a project's demand with it. The guidelines also highlight water use and noise as issues where host communities should not be left holding the bag, according to reporting by CommonWealth Beacon.
State officials say projects should show they will not cause local water scarcity, that they will limit air and noise pollution, and that they will minimize added system or infrastructure costs for municipal utilities. The message to would-be developers is clear: if your project strains local resources, do not expect the state to roll out the red carpet.
Industry pushback and local friction
Data center industry groups warn the pause could spook investors at a moment when companies are weighing big, long-term buildouts. Critics on the other side say the state has to protect residents from higher bills and overstretched infrastructure, especially as energy-hungry facilities rush to feed the artificial intelligence boom.
The Data Center Coalition, asked for comment, argued that the pause will discourage investment and stressed that data centers contribute to the broader economy. Neighbors in some host communities have been making the opposite case. In Lowell, residents living near the Markley data center have lodged complaints about a constant mechanical hum, and WBZ-TV reporting found the facility was using roughly 60,000 to 120,000 gallons of water per day, as reported by CBS Boston. That tension between local frustration and statewide economic ambitions is now front and center in the state's review.
Where things go from here
Healey's pause stays in place while state agencies, utilities and lawmakers work out enforceable guardrails. The move is part of a broader national rethink of generous data center incentives, according to Bloomberg Law, as states try to square big promises of tech investment with rising concern over power demand and local impacts.
The administration has folded data center policy into its Mass Wins economic package, positioning that bill as the likely vehicle for any tighter rules that end up in statute. Public materials on the proposal are available via Mass.gov, which indicates the legislation could ultimately be where new conditions on data center tax breaks are formally codified.
