Massachusetts’ business heavyweights are asking the state’s top judges to keep a major income tax cut alive, telling the Supreme Judicial Court to toss a lawsuit that could knock the proposal off the ballot before voters ever see it.

The initiative aims to trim the Commonwealth’s flat income tax from 5 percent to 4 percent over three years, with backers pitching it as a steady way to send more money back to households. Critics say the whole campaign rests on a flawed sales job and want the court to shut it down over what they describe as a crucial omission in the official summary used to gather signatures.

The legal fight

Opponents filed suit in early February, arguing that Attorney General Andrea Campbell’s summary of the ballot question did not spell out that the rate cut would also apply to long-term capital gains. That omission, they say, misled people who signed the petition and could mislead voters later, and should be enough to disqualify the measure before it advances to legislative review or the ballot, according to WGBH.

Supporters push back in court

Supporters of the tax cut are now asking the SJC to reject the challenge and let the question keep moving through the initiative pipeline. The Mass. High Technology Council and allied groups argue that the summary is accurate enough under the law and that tossing the petition at this stage would short-circuit a campaign that has already cleared early certification hurdles, according to a statement on the council’s website, Mass. High Tech Council.

What's at stake

Opponents warn the proposal could strip roughly $5 billion a year from state revenues, a hit they say would eventually show up as cuts to schools, local aid, and other core services. Supporters counter that the phase-in would soften the blow and point to modeling that pegs the average household benefit at about $1,300 once the cut is fully in place.

The campaign already cleared its first major hurdle last winter, when organizers reported submitting about 87,000 raw signatures to election officials, enough to push the proposal toward a possible Nov. 3 ballot spot. WBUR has broken down the competing fiscal estimates, while Massachusetts Lawyers Weekly has tracked the signature filings and certification steps that put the measure on the SJC’s radar.

How the court may rule

Under Massachusetts’ initiative rules, the attorney general must craft a “fair, concise summary” of any proposed ballot question. The SJC’s past decisions say that summary has to give voters enough information to understand the proposal without turning into a legal treatise.

In this case, legal analysts say the justices will focus on one key question: was leaving out long-term capital gains from the summary serious enough to mislead people signing the petition. A decision is not expected overnight. Observers say the ruling could take months and might not arrive until June. Those standards and timelines echo recent SJC opinions summarized by Justia.

Political backdrop

The fight arrives in the middle of an already tense budget and election season on Beacon Hill. Gov. Maura Healey has kept her distance so far, declining to stake out a public position. House Ways and Means Chair Aaron Michlewitz has not been shy, labeling the plan “irresponsible” and warning it could force lawmakers into painful trade-offs if revenues slide.

On the ground, unions and community organizations are lining up against the measure, while business and taxpayer groups are working to keep it alive. That tug-of-war is giving the court case extra political charge as the election year unfolds, according to Massachusetts Lawyers Weekly.

What happens next

If the SJC sides with the challengers, supporters might have to go back to square one on parts of the signature drive or look for other legal avenues to land a question on the ballot. If the court rejects the lawsuit, the petition moves deeper into the state’s certification process and on to the Legislature for review.

Either way, both sides say they are not going anywhere. Supporters insist they are ready for a longer legal and political slog, while opponents vow to keep pressing their case in court, according to WBUR.

Legal implications

Officially, the SJC is not ruling on whether cutting the tax rate is good or bad policy. The dispute is about process and wording, not ideology. Still, if the challengers win, it could raise the bar for how carefully initiative summaries are written and invite more preemptive lawsuits that try to knock ballot questions out on technical grounds.

Past rulings highlight the constitutional role the summary plays in informing voters, and the court’s upcoming decision could subtly rewrite how lawyers vet petition language and how campaigns frame their pitches, according to Justia.

For now, the tax cut proposal has moved from the campaign trail to the courtroom and into the center of this year’s political story. With the November ballot and Beacon Hill’s budget talks both in play, the Mass. High Technology Council says it will keep pushing its case to lawmakers and voters while the SJC decides how far this income tax fight will go.
