Massachusetts taxes most income at a flat 5%. Starting in 2023, a 4% surtax applies to annual income exceeding $1 million (the "millionaire's tax"), bringing the effective top rate to 9% on income above that threshold. The $1 million threshold is adjusted annually for inflation. Massachusetts does not have local income taxes. Short-term capital gains are taxed at 8.5%.
Regardless of state taxes, all Massachusetts workers pay federal income tax using the 2026 brackets: 10% on the first $11,925 of taxable income (single), 12% up to $48,475, 22% up to $103,350, 24% up to $197,300, 32% up to $250,525, 35% up to $626,350, and 37% on income above that. The standard deduction is $15,000 for single filers and $30,000 for married filing jointly in 2026.
All workers in Massachusetts pay Social Security tax at 6.2% on wages up to $176,100 (2026) and Medicare tax at 1.45% on all wages. An additional 0.9% Medicare surtax applies to wages over $200,000 for single filers. These federal payroll taxes apply uniformly regardless of which state you live in.
Pre-tax deductions reduce your taxable income for both federal and state purposes. Contributing to a 401(k) (up to $24,500 in 2026, plus $8,000 catch-up if 50+) lowers both your federal and MA state tax bill. Health Savings Account (HSA) contributions ($4,300 individual, $8,550 family in 2026) are also pre-tax. Review your W-4 withholding: if you receive a large refund each year, you may be overwithholding, which means less money in each paycheck. The Tax Bracket Calculator shows your federal marginal and effective rates.
