Massachusetts passed a millionaire's tax. Now, the revenue is paying for free public school lunches.

Every kid in Massachusetts will get a free lunch, paid for by proceeds from a new state tax on millionaires.

A new 4% tax on the state's wealthiest residents will account for $1 billion of the state's $56 billion fiscal budget for 2024, according to state documents. A portion of those funds will be used to provide all public-school students with free weekday meals, according to State House News Service.

The new tax, which was approved by voters last year and went into effect in 2023, applies to Massachusetts residents with incomes over $1 million. The new tax adds an extra 4% on earnings above that threshold, making the state's income tax rate one of the highest in the U.S.
