Summary

Since 1917, Massachusetts has had a flat-rate individual income tax. On November 8, 2022, voters approved amending the state's constitution to enact an additional 4% tax on individual taxable income greater than $1 million.

Beginning in 2023, Massachusetts will impose the additional 4% tax on taxable income greater than $1 million. The agency will adjust the $1 million income level annually to reflect increases in the cost of living by the same method used for federal income tax brackets.

Massachusetts will allocate revenue from the tax collected to public education and public transportation.
