How Massachusetts Paycheck Taxes Work
Massachusetts workers pay three layers of tax on every paycheck: federal income tax, Massachusetts state income tax, and FICA (Social Security and Medicare). Here is what each layer costs you in 2026.
Federal income tax
Federal income tax uses progressive brackets ranging from 10% to 37% depending on your taxable income and filing status. The 2026 standard deduction is $15,000 for single filers and $30,000 for married filing jointly, which reduces the income subject to tax before brackets apply.
Massachusetts state income tax
Massachusetts uses a flat 5.00% state income tax on all taxable income, regardless of how much you earn. The flat system makes your Massachusetts state tax straightforward to calculate — multiply your taxable income by 5.00%.
FICA taxes
FICA taxes are the same in every state. Social Security takes 6.2% of wages up to $176,100 in 2026. Medicare takes 1.45% with no cap. Workers earning above $200,000 (single) or $250,000 (married filing jointly) pay an additional 0.9% Medicare surtax.
What Reduces Your Massachusetts Take-Home Pay
Beyond taxes, several pre-tax deductions can lower your taxable income — and increase your net pay:
- 401(k) contributions reduce both federal and Massachusetts state taxable income. The 2026 limit is $23,500 per year ($31,000 if you are 50 or older). Every dollar you contribute pre-tax comes out of your paycheck before taxes are calculated.
- Health insurance premiums paid through your employer's cafeteria plan are pre-tax, reducing both income tax and FICA.
- HSA contributions through payroll are pre-tax for federal income tax, state income tax, and FICA. The 2026 limit is $4,300 for self-only and $8,550 for family coverage.
