Massachusetts Tax Calculator
Massachusetts has a flat 5% income tax plus a 4% surtax on income over $1.08M — effective top rate 9%.
Massachusetts technically has a flat 5% income tax but adds a 4% surtax on income above $1,080,450 (2025), creating an effective top rate of 9% for high earners — a surtax structure that has generated substantial revenue since its 2023 expansion. MA does not allow a standard deduction — taxpayers must itemize, though Massachusetts allows full deduction of contributions to 401(k)s, IRAs, and other qualified retirement accounts. The state sales tax is 6.25%, with most clothing under $175 exempt. Property taxes are above the national mean at ~1.22%, with significant variation between Boston-area towns and Western Massachusetts. Massachusetts exempts Social Security and most pension income, and offers a circuit-breaker tax credit for residents 65+ with high property tax burdens. The state's economy — anchored by biotech, finance, and higher education — provides a stable revenue base. The surtax has been credited with funding major transportation and education investments.
