SJC blocks – Massachusetts’ Supreme Judicial Court barred a proposed 2026 ballot question to cut the state income tax rate from 5% to 4%, ruling that the initiative’s official summary prepared by the attorney general’s office materially misstated how it would affect long-t
For a campaign built around affordability, the setback landed with courtroom finality. Massachusetts’ highest court ruled that a proposed ballot question to lower the state’s income tax rate cannot appear before voters in November because the initiative’s official summary was misleading about how the measure would work for long-term capital gains.
In a decision issued Thursday. June 18. 2026. the Supreme Judicial Court found that the summary prepared by Attorney General Andrea Campbell’s office failed to fairly describe the proposal’s effect on long-term capital gains taxes—an error the court said was significant enough to disqualify the initiative from the 2026 statewide ballot.
Justice Serge Georges Jr., writing for the court, said the summary incorrectly suggested that capital gain income would not be subject to the proposed tax reduction. Under current law, the court concluded, most long-term capital gains income would be affected.
“The summary does not merely leave something unsaid,” Georges wrote. “It affirmatively tells voters, in ordinary language, that capital gain income is outside the proposed tax reduction when, under current law, most long-term capital gain income would be affected.”
The court further said the summary “materially misstates” the measure’s scope and could not be fixed through campaign messaging or the official “yes” and “no” statements distributed to voters. “Because this summary materially misstates the true scope of the proposal, it is unfair,” Georges wrote.
At the center of the dispute is a ballot initiative designed to cut Massachusetts’ income tax rate from 5% to 4%. Supporters framed it as a direct response to the state’s cost-of-living pressures. Business advocates backed the proposal, and Boston.com readers also added their voices. Opponents—including legislators and other advocacy groups—argued it would significantly reduce state revenue and. in their view. deliver the largest benefits to high-income households while leaving middle- and lower-income residents to shoulder the consequences.
After the ruling, that fight reignited in statements from both sides.
The Massachusetts Opportunity Alliance, a business advocacy organization that backed the measure, criticized the decision. “Today’s unprecedented ruling prevents Massachusetts voters from weighing in on a popular proposal to address the state’s cost-of-living crisis. ” spokesperson Colin Reed said in a statement. Reed said the decision does not change broader concerns about affordability and competitiveness in Massachusetts. and added that the organization would continue advocating for policies designed to make the state more affordable for residents and businesses.
Leaders of the Protect Massachusetts’ Future ballot committee, which opposed the initiative, welcomed the court’s action. Shanique Rodriguez. executive director of the Massachusetts Voter Table. said in a statement that the ballot initiative would have delivered the largest tax breaks to the ultra-rich. while low-income and middle-class residents would have been stuck paying the price. She added that “Slashing local aid and public services to fund tax breaks that mostly benefit millionaires is the wrong direction for our communities. and we’re all better off without this initiative on the ballot.”.
A separate analysis from Tufts University’s Center for State Policy Analysis projected that households across the income spectrum would see relatively similar benefits from the tax cut. with most households keeping an additional 1% of their income. The study also found that higher-income households would see much more actual savings—roughly 30 times as much as the median household.
The Supreme Judicial Court’s ruling ends the contested initiative and leaves any future changes to Massachusetts’ income tax structure to lawmakers or to a new ballot campaign.
The decision does not just close a procedural door. It redraws the terms of a public debate that had already been unfolding in a state grappling with affordability—now moved out of voters’ hands for the 2026 election cycle, and back into the legislature’s.
