New Study Finds Massachusetts Is Not Progressive When It Comes to Taxing Lower- and Middle-Income Families
BOSTON – On the heels of last week’s unprecedented state Supreme Judicial Court (SJC) decision removing a widely supported income-tax reduction measure from the November ballot, a new Pioneer Institute study finds that Massachusetts taxes a far larger share of lower- and middle-income households' earnings compared to red and blue competitor states.
The Commonwealth's personal exemption remains at just $4,400 for single filers and $8,800 for married couples filing jointly—levels that have not changed since 2008 and have declined in inflation-adjusted value by 55 percent. If rates had been adjusted for inflation, they would have saved tax filers an additional $861 million in 2025. Current rates shield far less income from Massachusetts taxpayers than many competing and neighboring states.
