Massachusetts 5% Flat Tax — Not 9%

Massachusetts personal income tax is a flat 5% on most types of income — wages, salaries, interest, dividends, and short-term capital gains — per the Massachusetts Department of Revenue. The 9% figure many sites quote is the combined rate for high earners (5% flat + 4% Millionaire's Surtax) and applies only to taxable income above $1,083,150 in 2026 (the threshold is indexed annually). For about 99% of Massachusetts workers, the correct effective state rate is 5% — anyone showing you 9% on a $60,000 salary is over-taxing your estimate by roughly $2,400 per year.

Federal Tax + Massachusetts 5% — Real Take-Home Example

For a Massachusetts single filer earning $60,000 annually with no pre-tax deductions: federal income tax (2026 brackets) is about $5,309, the MA 5% flat tax is $3,000, Social Security $3,720, Medicare $870, and PFML ~$276. Total deductions ≈ $13,175 — leaving $46,825 net annual take-home, or roughly $1,800 biweekly. The federal brackets used: 10% on the first $11,925; 12% to $48,475; 22% to $103,350; 24% to $197,300; 32% to $250,525; 35% to $626,350; 37% above (single, 2026).

Massachusetts Millionaire's Surtax (4% above $1M)

Voters approved Question 1 in November 2022, adding a 4% surtax on taxable income above $1 million effective January 1, 2023. The threshold is indexed for inflation — for the 2026 tax year (filed in 2027), the trigger sits at approximately $1,083,150. The surtax applies to the marginal income above the threshold, not the entire return. Surtax revenue is constitutionally earmarked for education and transportation. If your total Massachusetts taxable income stays under $1.083M, the surtax does not apply — your effective state rate stays at the 5% flat rate.

Massachusetts PFML — What That Deduction Is

The line item on Massachusetts pay stubs labeled "PFML," "MA PFM," or "Mass Paid Family & Med Leave" is the employee share of the state's Paid Family and Medical Leave program (established 2018, mandatory contributions since October 2019). The 2026 total contribution rate is 0.88% of wages up to the Social Security wage base; employers with 25+ employees split this with workers (employee pays about 0.46% for medical leave + family leave). Smaller employers can cover the medical-leave share themselves, dropping the employee withholding to roughly 0.18%–0.46% depending on company size and benefit elections.

How to Use This Massachusetts Paycheck Calculator

Pick your pay period (weekly, biweekly, semimonthly, monthly, or annual). Enter gross pay per period — what shows on your offer letter or pay stub before any deductions — and select your federal filing status (single, MFJ, MFS, or HoH). Add any pre-tax deductions per period (401(k), HSA, or pre-tax health insurance), which lower both federal and Massachusetts taxable income. The output shows federal income tax, FICA (6.2% + 1.45%), Massachusetts 5% flat tax, the Millionaire's Surtax line (zero for most filers), and PFML — broken down per period and as an annual total.

How to Reduce Your Massachusetts Paycheck Tax Bite

The most effective way to lower your Massachusetts take-home tax bill is to maximize pre-tax payroll deductions — these reduce both federal AND Massachusetts taxable income at once. 2026 limits: 401(k) employee deferral $23,500 (catch-up adds $7,500 for age 50+, plus a higher $11,250 super-catch-up for ages 60–63 under SECURE 2.0). HSA limits: $4,300 self-only, $8,550 family. Pre-tax employer health insurance premiums and FSA contributions also reduce both taxable bases. Note that Roth 401(k) and Roth IRA contributions do not reduce current taxable income — they're after-tax. For a worker maxing 401(k) + HSA on a $90,000 salary, total annual tax savings are roughly $6,000–$7,000 compared with no pre-tax contributions.

Massachusetts vs Neighbouring States — Take-Home Comparison

Massachusetts' flat 5% state tax sits in the middle of the New England pack. New Hampshire (no wage tax) and Tennessee (no wage tax) effectively beat MA by 5 percentage points. Connecticut has a graduated 3%–6.99% structure, slightly favouring lower earners but worse at the top. Rhode Island is graduated 3.75%–5.99%. New York's NY state + NYC combined tax tops 14.776% — almost 3× Massachusetts for the same income. The Millionaire's Surtax pushes MA above neighbours only at the very top — for $1.5M of taxable income, MA's effective state burden becomes about 5.8%, still well below California (13.3%) or New York City (14.776%). Cross-border commuters (NH residents working in MA) generally pay MA tax on Massachusetts-sourced income, regardless of residence state.
