How Massachusetts State Income Tax Works

Massachusetts taxes most earned income at a flat 5% rate. The state does not use graduated brackets for ordinary income — unlike New York or New Jersey. Massachusetts calculates state income tax as follows:

1. Start with Massachusetts gross income — generally similar to federal AGI with Massachusetts-specific adjustments.
2. Subtract the personal exemption — Massachusetts uses a personal exemption system rather than a standard deduction: $4,400 for single filers, $8,800 for married filing jointly, $6,800 for head of household. Each dependent reduces taxable income by an additional $1,000.
3. Apply 5% (or 9% on income above $1,083,150) — the flat rate yields Massachusetts income tax.

For the vast majority of Massachusetts workers, only the 5% rate applies. The 9% surtax is relevant only to those earning more than $1,083,150 per year.

The Fair Share Amendment — Massachusetts' 9% Surtax

Massachusetts voters approved Question 1 (the Fair Share Amendment) in November 2022, adding a 9% income tax rate on annual income above approximately $1,083,150 (indexed for inflation). This applies to the portion of income above the threshold, not to all income. For a filer with $1,200,000 in income:

• First $1,083,150 taxed at 5% = $54,158
• Remaining $116,850 taxed at 9% = $10,517
• Total Massachusetts state tax = $64,675

Federal Income Tax — Progressive Brackets

On top of Massachusetts state tax, every Massachusetts worker owes federal income tax based on the 2026 progressive brackets from 10% to 37%.

Step-by-Step Example — $80,000 Single Filer in Massachusetts

1. Gross annual pay: $80,000
2. Federal taxable income: $80,000 − $16,100 standard deduction = $63,900. Federal income tax (10%/12%/22% brackets): ≈ $7,370.
3. Massachusetts taxable income: $80,000 − $4,400 personal exemption = $75,600. MA tax at 5%: $3,780.
4. FICA: 7.65% × $80,000 = $6,120.
5. Estimated net take-home: ≈ $62,730/year (≈ $2,412 biweekly).

FICA Taxes — Social Security and Medicare

• Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you cross the wage base for the year.
• Medicare: 1.45% on all wages with no cap. Additional 0.9% Medicare surtax on wages above $200,000 single / $250,000 MFJ.
• Employer match: your employer matches Social Security and base Medicare; the Additional Medicare surtax is employee-only.

No Local Income Tax in Massachusetts

Massachusetts has no local or city income tax. Boston, Cambridge, Worcester, Springfield, and all other Massachusetts municipalities do not impose a local payroll income tax. This distinguishes Massachusetts from states like New York (where NYC residents pay 3%+ city income tax) or Maryland (where every resident must pay a county income tax). Massachusetts cities fund themselves primarily through property taxes and state distributions.

Massachusetts vs. Neighboring States

• vs. Connecticut:CT uses progressive brackets from 2% to 6.99%. A $100,000 CT single filer pays roughly $4,700 in state tax — slightly less than Massachusetts' ~$4,780.
• vs. Rhode Island: RI has progressive brackets from 3.75% to 5.99%. Comparable to Massachusetts for most middle-income earners.
• vs. New Hampshire: NH has no income tax on wages (only taxes interest and dividend income, and that tax is being phased out). NH residents working in Massachusetts generally owe MA income tax on wages earned in the state.
• vs. New York: NY uses progressive brackets up to 10.9%; NYC residents add 3–3.9% city tax. A New York City earner at $100,000 pays $8,000–$9,000 more in total income taxes than a Massachusetts resident.

How to Maximize Your Massachusetts Take-Home Pay

• Max your 401(k) — pre-tax 401(k) contributions reduce both federal and Massachusetts taxable income. At 5% MA + 22% federal = 27% combined marginal rate, a $20,000 contribution saves about $5,400 in annual taxes.
• Contribute to an HSA — $4,300 (self-only) or $8,550 (family) for 2026. Massachusetts recognizes HSA contributions as pre-tax reductions to state taxable income.
• Use a Dependent Care FSA — up to $5,000 per family pre-tax reduces both federal and Massachusetts taxable income for qualifying childcare expenses.
• Massachusetts ABLE accounts — contributions to Massachusetts ABLE accounts for residents with disabilities are deductible up to $18,000 per year from Massachusetts taxable income.
• Update Form M-4 — Massachusetts uses its own withholding form (M-4). Update it when your filing status, dependents, or pre-tax deductions change to avoid significant over- or under-withholding.
