Massachusetts Paycheck Calculator 2026 — 9% Top State Rate (Federal + FICA + State)

How much do I take home in Massachusetts? — short answer first

Massachusetts levies a flat 5% individual income tax on wages and salary — a rate unchanged since 2020. In 2022, Massachusetts voters approved Article 44 (the 'Fair Share Amendment'), adding a 4% surtax on taxable income above $1 million effective 2023. The net structure is now effectively two brackets: 5% to $1M, 9% above. For most working adults, the 5% rate plus a $4,400 single / $8,800 joint personal exemption is the relevant math. Massachusetts also imposes a Paid Family + Medical Leave (PFML) payroll deduction of ~0.46% on the employee share. Boston has no local income tax — the city funds itself through property tax (~1.02% effective).

How Massachusetts taxes payroll in 2026

Massachusetts levies a flat 5% individual income tax on most taxable income under M.G.L. c. 62, §4. The 5% rate has been stable since 2020 (prior years saw incremental cuts from 6.25% in 2000). In November 2022, Massachusetts voters approved Question 1 (the 'Fair Share Amendment'), adding a 4% surtax on taxable income above $1 million — effective for tax years 2023 onward. The combined effect: 5% on the first $1M of taxable income, 9% on anything above. The Fair Share Amendment is constitutional (Article 44 of the Mass. Constitution), making it difficult to reverse without another ballot vote. Massachusetts has no standard deduction; instead, the state uses a personal exemption: $4,400 single, $8,800 married joint, $6,800 head of household (2024 base, with annual COLA). A single $75,000 earner pays approximately: ($75K - $4,400 exemption) × 5% = $3,530 in MA state income tax. Massachusetts also imposes a Paid Family + Medical Leave (PFML) payroll deduction under M.G.L. c. 175M. The combined employer + employee premium is ~0.88%, with the employee share approximately 0.46% in 2026 (split varies between family-leave portion and medical-leave portion). PFML funds 26 combined weeks of paid leave for medical, family caregiving, and new-child bonding. Massachusetts has no local income tax — Boston, Cambridge, Somerville, and Worcester all fund services through property tax (~1.02% effective statewide) and 6.25% sales tax. Massachusetts has no reciprocity agreements with neighbouring states. New Hampshire residents working in Massachusetts owed MA state tax during the 2020-2021 remote-work surge, sparking the SCOTUS dispute that ultimately did not resolve the issue — current practice is that physical presence in MA triggers MA withholding.

How to use this calculator

1. Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
2. Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and Massachusetts brackets.
3. Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
4. Pick your locality. Drives local-tax stacking (NYC, Yonkers, etc). NONE if you live outside any locality with local payroll tax.
5. Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

• Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
• Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
• Using the wrong filing status for state tax. Massachusetts uses the same filing status categories as the IRS, but bracket thresholds differ from federal. Pick the status that matches your actual tax filing — not just what gives the best number.
• Not selecting your locality. If you live in a city with local payroll tax (NYC, Yonkers, etc.), the locality dropdown above is required for accurate math.
• Ignoring multi-state implications. If you work in Massachusetts but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in Massachusetts.
