Massachusetts Just Added a 9% Millionaire Tax — What Every 2026 Paycheck Now Keeps
Massachusetts built its tax reputation on being relatively straightforward — a flat 5% income tax rate that applied equally to everyone from minimum wage workers to millionaires. That simplicity ended in January 2023 when Massachusetts voters approved a constitutional amendment adding a 4% surtax on all income above $1 million per year — effectively creating a two-tier system with a 5% rate for most workers and a 9% combined rate for high earners. For the vast majority of Massachusetts workers earning below $1 million the flat 5% rate still applies and the paycheck calculation remains clean. But for the growing number of tech executives, finance professionals, and business owners in Boston and Cambridge whose total annual income crosses that threshold — including capital gains, business income, and wages combined — Massachusetts has become one of the most expensive states in America for high earners. The take home pay calculator on CalcMint Pro gives you the exact 2026 numbers for any Massachusetts salary instantly.
Massachusetts Income Tax Structure (2026)
Unlike most states with complex bracket systems Massachusetts keeps its wage income tax simple for most workers.
| Massachusetts Taxable Income | Tax Rate |
|---|---|
| $0 — $1,000,000 | 5% flat rate |
| Above $1,000,000 | 9% (5% base + 4% surtax) |
Massachusetts offers a personal exemption rather than a standard deduction — $4,400 for single filers and $8,800 for married filing jointly in 2026. This is more generous than Maryland's $2,400 standard deduction but far below Colorado's $15,000 or the federal $15,000. Most Massachusetts workers apply the flat 5% to the vast majority of their gross wages after subtracting the personal exemption.
Massachusetts also has no local income taxes anywhere in the state — not in Boston, Cambridge, Worcester, or Springfield. Workers pay the state flat rate once with no additional city or county layer on top. This is a meaningful advantage compared to Maryland where county taxes add up to 3.20% on top of state tax or New York City where the local tax adds nearly 3.876% on top of New York State tax.
The Massachusetts Paycheck Formula (Plain English)
Gross Pay − Pre-Tax Deductions (401k, health insurance, HSA/FSA — reduces both federal and Massachusetts taxable income) − Massachusetts Personal Exemption ($4,400 single / $8,800 married) − Massachusetts State Income Tax (5% flat on income up to $1 million; 9% on income above $1 million) − Federal Income Tax (IRS 2026 progressive brackets) − Social Security Tax (6.2% up to $176,100 wage base) − Medicare Tax (1.45% on all wages; +0.9% above $200,000) = Massachusetts Net Take-Home Pay
For workers earning below $1 million the calculation is among the simplest of any income-tax state — multiply taxable wages by 5% and that is your Massachusetts state tax. The complexity only enters for very high earners where the surtax kicks in and where the definition of income subject to the surtax — which includes capital gains, business income, and other non-wage sources in addition to wages — becomes critically important.

How to Use the CalcMint Pro Take-Home Pay Calculator for Massachusetts
Step 1 — Enter your Massachusetts gross salary or hourly wage. Boston area workers in tech, biotech, finance, and healthcare often receive total compensation packages combining salary, bonus, and equity — for paycheck purposes enter only your base salary gross figure. If you are paid hourly use the hourly to salary calculator to convert before running the full Massachusetts calculation.
Step 2 — Select Massachusetts as your state. The calculator loads the flat 5% rate and personal exemption automatically. For workers whose total annual income approaches or exceeds $1 million the surtax calculation requires knowing your total income from all sources — not just wages — since the $1 million threshold applies to combined income.
Step 3 — Choose your filing status. Married filers receive an $8,800 personal exemption versus $4,400 for single filers — double the shelter before the 5% rate applies. At high income levels this difference is relatively small in dollar terms but every exemption dollar saves $0.05 in Massachusetts state tax.
Step 4 — Add pre-tax deductions. Massachusetts recognises traditional 401k contributions as pre-tax for state income tax purposes — unlike New Jersey. On a $110,000 Massachusetts salary contributing $15,000 to a 401k saves approximately $750 in Massachusetts state tax in addition to the federal saving. The pre-tax vs post-tax deductions guide explains how to maximise this across both tax levels.
Step 5 — View your Massachusetts net pay breakdown. Federal tax, Massachusetts flat state tax, Social Security, and Medicare all appear as separate lines. The calculation is notably cleaner than multi-bracket states like Minnesota or Maryland because the flat 5% applies uniformly to most workers.
Massachusetts vs Neighbouring States: The $100,000 Salary Comparison
New England workers frequently compare Massachusetts against Connecticut, New Hampshire, Rhode Island, and Maine. Here is the real take-home on a $100,000 salary across the region.
| State | State Tax | Federal Tax | FICA | Annual Take-Home | vs Massachusetts |
|---|---|---|---|---|---|
| New Hampshire | $0 | ~$16,124 | ~$7,650 | ~$76,226 | +$5,806 more |
| Maine | ~$4,500 | ~$16,124 | ~$7,650 | ~$71,726 | +$1,306 more |
| Massachusetts | ~$4,780 | ~$16,124 | ~$7,650 | ~$71,446 | baseline |
| Rhode Island | ~$5,000 | ~$16,124 | ~$7,650 | ~$71,226 | −$220 less |
| Connecticut | ~$5,500 | ~$16,124 | ~$7,650 | ~$70,726 | −$720 less |
| New York State | ~$6,450 | ~$16,124 | ~$7,650 | ~$69,776 | −$1,670 less |
| New York City | ~$10,140 | ~$16,124 | ~$7,650 | ~$66,086 | −$5,360 less |
The New Hampshire comparison is the most dramatic in New England. New Hampshire charges zero state income tax on wages — making it the closest no-tax state to Boston. A Massachusetts worker earning $100,000 pays approximately $4,780 in state income tax that a New Hampshire worker at the same salary pays nothing. Over a 10-year career that gap totals $47,800 — which is precisely why the New Hampshire border towns of Nashua and Manchester have seen significant population growth from Boston-area workers who work remotely or commute.

Who Uses the Massachusetts Paycheck Calculator Most
Boston biotech and pharmaceutical workers — Massachusetts is the global centre of the biotech industry with hundreds of companies in the Kendall Square, Waltham, and Route 128 corridors. Scientists, researchers, and executives in this sector earn salaries ranging from $70,000 for entry-level roles to well above $300,000 for senior positions — and the flat 5% Massachusetts rate applies consistently across that entire range below the millionaire threshold.
Technology workers at Boston and Cambridge startups who receive base salary plus equity compensation. When stock options vest and are exercised the resulting income may push total annual earnings above the $1 million surtax threshold — creating a sudden jump from 5% to 9% on the excess that can mean tens of thousands of dollars in additional Massachusetts tax in a single year.
Workers considering relocation to New Hampshire — the most searched comparison for Massachusetts workers on a budget. NH has no income tax on wages, housing costs are lower in most NH markets than comparable Boston suburbs, and the Massachusetts border is within commuting distance of much of southern NH. For fully remote workers the financial case for relocating from Massachusetts to New Hampshire is straightforward — approximately $4,800 per year in tax savings on a $100,000 salary with no commuting cost increase.
Healthcare workers at Massachusetts General, Brigham and Women's, and other major Boston hospital systems who want to understand their exact take-home before accepting shift assignments or overtime. The overtime calculator combined with the Massachusetts 5% flat rate helps nurses and technicians model their real net overtime rate accurately — Massachusetts overtime earnings are taxed at the same 5% state rate as regular wages making the calculation straightforward.
Federal employees and military personnel stationed at Massachusetts installations including Hanscom Air Force Base, Natick Labs, and the various Coast Guard facilities. Military base pay is subject to Massachusetts income tax for MA residents — unlike some states that exempt military pay from state taxation.
Real-World Example: $88,000 Salary in Boston
Priya is a data scientist at a Cambridge biotech firm earning $88,000 per year paid biweekly. She files as single, contributes 8% to her 401k, and pays $125 per biweekly period for health insurance pre-tax.
Gross biweekly pay: $3,384.62 401k (8%): −$270.77 (reduces both federal and Massachusetts taxable income) Health insurance: −$125.00 Adjusted gross per period: $2,988.85
Massachusetts taxable income annualised after $4,400 personal exemption and pre-tax deductions: approximately $67,844 Massachusetts state tax (5% flat, annualised): ~$3,392 (~$130.46 per biweekly period) Federal income tax (estimated): ~$287.00 per biweekly period Social Security (6.2%): ~$185.46 Medicare (1.45%): ~$43.37
Priya's Massachusetts net take-home: approximately $2,217.56 per paycheck — roughly $57,657 per year.
When Priya receives her annual $12,000 performance bonus she runs it through the bonus tax calculator. At 22% federal flat withholding plus 5% Massachusetts state tax plus 7.65% FICA, her $12,000 bonus nets approximately $8,202 — she directs $5,000 into her emergency fund and uses the remaining $3,202 to make an additional 401k contribution before the year-end deadline.
Priya is tracking her total annual income carefully — her base salary, bonus, and a small amount of investment income combined. If her total income ever approaches $1 million the Massachusetts surtax would apply to the excess at 9% rather than 5% — a $40,000 additional tax bill on $1 million of income that requires careful planning to manage efficiently.
The Massachusetts Millionaire Tax — Who It Actually Hits
When Massachusetts voters approved the 4% surtax in November 2022 the debate centred on whether it would primarily affect hedge fund managers and tech billionaires or reach more ordinary high earners. The reality in 2026 is that the $1 million threshold is not indexed to inflation — meaning as wages and investment returns grow over time, more workers will gradually cross the threshold.
Currently the surtax primarily affects:
Business owners whose pass-through business income combines with wages to cross the $1 million threshold in successful years.
Tech executives with large equity grants that vest in single calendar years — a $400,000 base salary plus $700,000 in vesting RSUs crosses the threshold and subjects the $100,000 excess to the 9% combined rate.
Real estate investors and developers whose property sale gains count toward the $1 million threshold in years they complete large transactions.
High-earning physicians and attorneys in private practice whose combined professional income approaches or exceeds the threshold.
For these workers Massachusetts has become meaningfully more expensive since 2023 — and the data shows it. Massachusetts recorded net out-migration of high-income households to Florida, New Hampshire, and Texas in 2023 and 2024 at rates above historical averages. The salary raise calculator helps workers in this category model exactly what gross income they need to maintain a target after-tax income as their earnings approach the surtax threshold.
Pro Tip: Massachusetts Flat Rate Makes Overtime and Bonuses Predictable
One genuine advantage of Massachusetts's flat 5% rate is that every additional dollar of income — whether from a raise, overtime, or a bonus — is taxed at exactly the same state rate. There are no surprise bracket jumps where earning slightly more triggers a higher rate on your existing income. For workers below the $1 million threshold Massachusetts state tax on any additional earnings is always exactly 5 cents per dollar — making income planning and budgeting more predictable than in progressive states like Minnesota or New Jersey where additional income can push into materially higher brackets. Use the overtime calculator alongside the flat 5% Massachusetts rate to model any overtime scenario quickly — the state tax portion of the calculation never changes regardless of how many hours you work.

Frequently Asked Questions
What is Massachusetts state income tax rate for 2026?
Massachusetts has a flat 5% state income tax rate for all wage income up to $1 million per year in 2026. Income above $1 million is subject to an additional 4% surtax — called the Millionaire Tax — bringing the combined rate to 9% on the excess. The surtax applies to total income from all sources including wages, capital gains, and business income combined — not just wages alone.
How much does an $85,000 salary take home in Massachusetts?
A single filer earning $85,000 in Massachusetts takes home approximately $62,847 per year or $5,237 per month in 2026 after federal income tax of roughly $11,124, Massachusetts flat state tax of approximately $4,030 on income above the $4,400 personal exemption, and FICA of $6,503. Massachusetts has no local income taxes anywhere in the state so there are no additional city or county deductions beyond the flat state rate.
Does Massachusetts tax bonus income at 5%?
Yes — Massachusetts taxes all supplemental wages including bonuses, commissions, and overtime at the same flat 5% state rate as regular wages for income below $1 million. This makes Massachusetts bonus tax calculations straightforward — federal withholding at 22% plus Massachusetts at 5% plus FICA at 7.65% means most Massachusetts workers keep approximately 65 cents of every bonus dollar below the $1 million threshold.
How does Massachusetts paycheck compare to New Hampshire?
New Hampshire charges zero state income tax on wages making it the closest no-tax state to Massachusetts. A single filer earning $100,000 in Massachusetts pays approximately $4,780 in state income tax that a New Hampshire worker at the same salary pays nothing. Over a 10-year career that gap totals nearly $48,000 — which is why many remote workers and commuters have relocated from Greater Boston to southern New Hampshire border towns like Nashua and Manchester in recent years.
