Business interests in Massachusetts, led by the Massachusetts High Tech Council, Associated Industries of Massachusetts and the Massachusetts Taxpayers Foundation among others, have initiated litigation challenging the placement of the so-called Millionaire Tax on the state ballot in November. The action, filed with the state Supreme Court this week, asks the court to declare the question of applying an extra 4% tax on incomes over $1 million in violation of the state constitution because it essentially establishes a graduated income tax and also illegally usurps the legislative function and authority of budgeting and controlling the state’s finances into the state constitution.
