Massachusetts income tax explained
Massachusetts has a flat 5% income tax with an additional 4% on incomes over $1 million.
Massachusetts's state income tax rate of 5.0% applies to your taxable income. Depending on your income level and filing status, you may owe slightly more or less than this rate due to progressive tax brackets and deductions. Some cities and counties in Massachusetts may also impose local income taxes.
Federal taxes that apply in Massachusetts
All workers in Massachusetts pay the same federal taxes. Federal income tax uses seven progressive brackets (10%, 12%, 22%, 24%, 32%, 35%, and 37%) applied to your income after the standard deduction ($$14,600 for single filers, $29,200 for married couples filing jointly, and $21,900 for heads of household).
FICA taxes include Social Security (6.2% on wages up to $168,600 in 2025) and Medicare (1.45% on all wages). If you earn over $200,000 ($250,000 married filing jointly), you also pay an additional 0.9% Medicare surtax. Self-employed individuals pay both the employer and employee portions (15.3% total).
Factors that affect your Massachusetts paycheck
Several factors beyond income taxes affect your net pay: pre-tax deductions like 401(k) contributions, health insurance premiums, and flexible spending accounts (FSAs) reduce your taxable income. Post-tax deductions like Roth IRA contributions do not affect your current tax bill but reduce your take-home pay.
Your W-4 withholding allowances determine how much federal tax is withheld from each paycheck. If you consistently receive large refunds, you may want to adjust your W-4 to increase your per-paycheck take-home pay instead of waiting for a refund.
