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 Paycheck Calculator for Remote & Hybrid Workers
Remote and hybrid work created a headache for the Massachusetts paycheck: which state gets your income tax? The general rule per the Mass.gov DOR filing guide is that MA taxes wages "sourced" to Massachusetts — meaning wages you earn for work physically performed in the state. A New Hampshire resident who commutes to a Boston office pays MA tax on Massachusetts-workdays only; work-from-home days performed in NH are typically not MA-sourced (the pandemic-era "convenience rule" that briefly claimed otherwise was ruled unconstitutional). If you split time between MA and another state, keep a workday log — the calculator above assumes 100% MA-sourced income and will over-estimate MA state tax if you actually worked out-of-state for part of the year. File a Form 1-NR/PY (non-resident/part-year) to allocate correctly.
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.
Massachusetts Paycheck Take-Home by Salary (2026 Quick Reference)
Sanity-check the calculator's net pay against these 2026 reference figures — single filer, standard deduction, no 401(k) or pre-tax deductions, 100% MA-sourced income. Federal brackets per the IRS 2026 inflation adjustments; Massachusetts flat 5% per Mass.gov DOR; PFML worker share 0.208% up to the SSA wage base per the Mass.gov PFML page:
- $50,000 gross → ~$38,910 take-home (~$3,243/mo) | effective tax ~22.2%
- $75,000 gross → ~$56,590 take-home (~$4,716/mo) | effective tax ~24.5%
- $100,000 gross → ~$72,760 take-home (~$6,063/mo) | effective tax ~27.2%
- $150,000 gross → ~$104,240 take-home (~$8,687/mo) | effective tax ~30.5%
- $250,000 gross → ~$166,340 take-home (~$13,862/mo) | effective tax ~33.5%
Married-filing-jointly take-home runs roughly 3–7 % higher at the same gross because of the higher federal standard deduction ($30,000 in 2026). Above $1,083,150 the Millionaire's Surtax kicks in — the calculator applies it automatically.
Paycheck Calculator Massachusetts: Bonuses, RSUs, and Supplemental Wage Withholding
The paycheck calculator massachusetts above assumes regular wages, but bonuses and RSU vests are withheld differently. Per IRS Publication 15 (Circular E, 2026), employers must withhold federal supplemental wages at a flat 22% (or 37% above $1M/year) instead of running them through your W-4 elections. Massachusetts DOR requires supplemental wages to be withheld at the flat 5% state rate per 830 CMR 62B.2.1. Combined with 6.2% Social Security + 1.45% Medicare + 0.208% PFML, a $10,000 Boston-based bonus arrives as roughly $6,530 net — not the ~$7,100 the regular calculator would suggest. If you're a Boston tech RSU-holder, run the calculator on your base salary, then subtract 22% federal + 5% state + 7.65% FICA from any supplemental line item separately. Updated 2026-07-28.
Updated 2026-07-28. Results are 2026 estimates based on published federal IRS brackets and Massachusetts DOR rates. Actual withholding may differ based on W-4 elections, additional voluntary withholding, M-4 state allowances, or contributions to retirement plans.

Frequently Asked Questions
What is the Massachusetts state income tax rate?
Massachusetts personal income tax is a flat 5% on most types of income (wages, interest, dividends, short-term capital gains). A separate 4% Millionaire's Surtax applies only to taxable income above $1,083,150 in 2026 — for almost all wage earners, the effective state rate is 5%.
Is Massachusetts state tax really 9%?
Not for most workers. The 9% figure is the combined rate (5% flat + 4% Millionaire's Surtax) and only applies to taxable income above ~$1.08M in 2026. Sites quoting 9% as the standard Massachusetts paycheck tax rate are over-estimating tax for any earner below the surtax threshold.
How is take-home pay calculated in Massachusetts?
Take-home is gross pay minus federal income tax (10%–37% across 2026 brackets), Social Security 6.2% (capped at $176,100 wage base), Medicare 1.45%, the Massachusetts 5% flat state tax, the PFML employee share (~0.46%), the 4% surtax on any income above $1.083M, and any pre-tax deductions you elected (401(k), HSA, pre-tax health insurance).
Does Massachusetts give a standard deduction?
No. Unlike federal tax, Massachusetts does not allow a standard deduction. The 5% flat rate is applied to Massachusetts taxable income (gross pay minus pre-tax 401(k), HSA, and certain other adjustments). MA does allow specific deductions and exemptions (personal exemption, dependents, rent, commuter expenses) — but no broad standard deduction.
What is the Massachusetts PFML deduction on my paystub?
PFML (Paid Family & Medical Leave) is a state-mandated payroll contribution that funds paid family and medical leave benefits. In 2026, the total contribution rate is 0.88% of wages up to the Social Security cap. Employers with 25+ workers split it; the employee share is roughly 0.46% (medical-leave portion). Smaller employers may absorb more of the cost.
Is the Millionaire's Surtax really in effect in Massachusetts?
Yes. Massachusetts voters approved Question 1 in November 2022, adding a 4% surtax on taxable income above $1 million. It took effect January 1, 2023 and is indexed for inflation — the 2026 threshold is approximately $1,083,150. Revenue is constitutionally earmarked for education and transportation.
Why does Massachusetts tax me at a flat rate when federal tax is bracketed?
Massachusetts adopted a flat-rate income tax through its 1915 constitutional amendment, which until 2023 prohibited graduated state income tax rates. Question 1 (2022) created the first true graduated component (the 4% surtax above $1M). Beneath that threshold, every Massachusetts taxpayer pays the same 5% rate — no brackets, no graduation.
I work remotely from New Hampshire for a Massachusetts employer — do I pay MA tax?
Only on wages earned for work physically performed in Massachusetts. NH residents who work in MA some days and remotely from NH other days pay MA tax on the MA-workday portion of wages only. Keep a workday log and file MA Form 1-NR/PY to allocate. The pandemic-era 'convenience of the employer' rule that briefly taxed 100% of NH remote work as MA-sourced was ruled unconstitutional — do not use it.
How accurate is this Massachusetts paycheck calculator for 2026?
Rates are verified against the 2026 IRS inflation adjustments (Rev. Proc. 2025-32) and Mass.gov DOR tables. Federal 2026 brackets, standard deduction ($15,000 single / $30,000 MFJ), Social Security wage base ($176,100), and the MA millionaire surtax threshold ($1,083,150) are all current as of July 2026. Actual paycheck withholding may differ based on your W-4 elections, M-4 state allowances, additional voluntary withholding, and specific pre-tax elections — treat the result as a strong estimate, not a substitute for your payroll provider's exact numbers.
What is the take-home pay on a $100,000 salary in Massachusetts in 2026?
Approximately $72,760 per year (~$6,063/mo) for a single filer using the standard deduction with no 401(k) contributions. Effective tax burden is about 27.2%, made up of ~15% federal + 5% MA flat + 6.2% Social Security + 1.45% Medicare + ~0.208% PFML employee share. Maxing a $23,500 401(k) pushes take-home closer to $79,000 by shielding that amount from both federal and MA state tax.
Do I get a lower Massachusetts paycheck if I move above the $1M surtax threshold?
Only on the dollars above $1,083,150 (the 2026 indexed threshold). The 4% Millionaire's Surtax is added only to income above that line — not retroactively to the whole salary. A $1.2M earner pays 5% on $1,083,150 and 9% (5%+4%) on the last $116,850, adding roughly $4,674 to the state tax bill. Below the threshold, the surtax does not apply at all.
