Massachusetts vs New Hampshire for Remote Workers: The Live-Free-or-Die Tax Gap

Massachusetts and New Hampshire share one of the most analytically clean state-to-state tax borders in the country. Massachusetts applies a flat 5.0% income tax on most income under M.G.L. c.62, §4, layered with a 4% millionaire surtax above $1 million and a Paid Family & Medical Leave (PFML) payroll tax. New Hampshire levies no tax on wages at all under RSA Chapter 77, and fully repealed its Interest & Dividends tax effective January 1, 2025 under 2021 New Hampshire Chapter 73. The result is a tax gap that ranges from $4,000 annually at $75,000 of income to more than $25,000 at $500,000.

Despite the gap, the Massachusetts-New Hampshire corridor remains heavily traveled in both directions. Massachusetts anchors the Boston technology and biotechnology economy with employers like Moderna, Vertex, and Google's Cambridge office, while New Hampshire offers lower housing costs, no income tax, and a 60-minute commute to Boston from southern towns like Nashua, Salem, and Portsmouth. The Massachusetts Department of Revenue audits moves to no-tax states aggressively, applying the domicile factors in Technical Information Release 95-5 and the 183-day statutory residency rule under M.G.L. c.62, §1(j). This guide works through the math at $75,000, $200,000, and $500,000.

The headline comparison

The table below summarizes the structural tax differences between Massachusetts and New Hampshire for the 2025 tax year. Figures are drawn from the Massachusetts Department of Revenue, the New Hampshire Department of Revenue Administration, the New Hampshire Employment Security agency, and the relevant state statutes cited inline.

Income tax comparison at $75,000

Consider a single filer earning $75,000 in wage income in 2025. A Massachusetts resident subtracts the $4,400 personal exemption, producing taxable income of $70,600. The Massachusetts flat income tax of 5.0% applies, producing tax of $3,530. The Massachusetts PFML premium adds approximately 0.66% combined — roughly $495 in employee contributions (with the medical portion capped at the $21,000 wage base and the family portion uncapped). The combined Massachusetts burden is approximately $4,025 per year.

A New Hampshire resident earning $75,000 pays $0 in state income tax. The New Hampshire Employment Security SUI is employer-paid only, with no employee deduction. The repealed I&D tax had never applied to wages in any event. The total New Hampshire burden at $75,000 is $0. The direct annual savings of approximately $4,025 is meaningful for a household at this income level, particularly when compounded with the absence of state sales tax on consumer purchases.

Income tax comparison at $200,000

At $200,000 of wages, the gap widens substantially. The Massachusetts resident subtracts the $4,400 personal exemption, producing taxable income of $195,600. The 5.0% flat rate produces income tax of $9,780. PFML adds approximately $1,320 in employee contributions, with the medical portion capped at $21,000 of wages but the family portion uncapped on all $200,000. The combined Massachusetts burden is approximately $11,100 per year.

The New Hampshire resident at $200,000 pays $0 in state income tax and $0 in PFML. The direct annual savings of approximately $11,100 is substantial, particularly when paired with the absence of state sales tax. A high-spending household that pays $40,000 annually on taxable consumer goods saves an additional $2,500 in Massachusetts sales tax that they would otherwise owe. The total Massachusetts-to-New Hampshire savings at $200,000 approaches $13,600 — a figure that explains the strong migration flow from Boston suburbs into southern New Hampshire towns.

Income tax comparison at $500,000

At $500,000 of wages, the Massachusetts progressive structure (technically flat with a surtax threshold) approaches but does not yet engage the 4% millionaire surtax, which applies only above $1 million of taxable income. Taxable income after the personal exemption is $495,600. The 5.0% flat rate produces income tax of $24,780. PFML adds approximately $1,000 in employee contributions (family portion uncapped at 0.14% of $500,000 = $700; medical portion capped at 0.52% of $21,000 = $109). The combined Massachusetts burden is approximately $25,780 per year.

The New Hampshire resident at $500,000 pays $0. The direct annual savings of approximately $25,780 is the largest in this comparison, and it compounds further above $1 million of income where the Massachusetts millionaire surtax kicks in. At $2 million of income, the Massachusetts burden would be approximately $94,000 (5.0% on $1M plus 9.0% on the second $1M), while the New Hampshire burden remains $0 — a $94,000 annual gap. This is why the Boston-to-New-Hampshire corridor is particularly active among business sellers, executives with large equity vesting events, and partners at Boston professional service firms.

Beyond income tax: the full tax picture

Property tax cuts sharply in New Hampshire's disfavor. New Hampshire's effective property tax rate of approximately 1.77% of market value is the third-highest in the United States, driven by the state education property tax under RSA 198:39 and limited commercial tax base in many towns. Massachusetts's effective rate of approximately 1.12% is meaningfully lower. A homeowner with a $700,000 home pays approximately $12,390 in New Hampshire property tax versus $7,840 in Massachusetts — a $4,550 annual premium that partially offsets the income tax savings at lower income levels.

Sales tax favors New Hampshire decisively. Massachusetts levies 6.25% under M.G.L. c.64H on most consumer goods, while New Hampshire levies no general sales tax (the meals and rooms tax of 9% under RSA 78-A applies only to restaurant meals, hotels, and vehicle rentals). A household spending $40,000 annually on taxable consumer goods saves approximately $2,500 in Massachusetts sales tax by relocating to New Hampshire. Vehicle purchases represent a particularly large savings — a $50,000 vehicle purchase triggers $3,125 in Massachusetts sales tax and $0 in New Hampshire.

Estate tax is another major differentiator. Massachusetts levies an estate tax under M.G.L. c.65C with a $2 million exemption (one of the lowest in the country) and a graduated rate up to 16%. New Hampshire has no estate tax and no inheritance tax. For a household with a $5 million estate, the Massachusetts estate tax could exceed $400,000, while the New Hampshire estate tax is $0. This makes New Hampshire particularly attractive for retirees and high-net-worth households, and is a major driver of the Cape Cod-to-New-Hampshire retirement migration pattern. Gasoline tax slightly favors New Hampshire (approximately 24 cents per gallon versus Massachusetts's 31 cents per gallon under M.G.L. c.64A).

Cost of living comparison

Housing costs favor New Hampshire substantially outside the immediate Boston core. Median home prices in southern New Hampshire towns (Nashua, Salem, Portsmouth) range from $500,000 to $700,000, while comparable Boston suburbs (Newton, Lexington, Brookline) range from $900,000 to $1.5 million. The Boston metro is the third-most-expensive housing market in the country after San Francisco and New York. Rental costs follow a similar pattern, with Boston one-bedroom apartments renting for $2,800-$3,500 versus $1,800-$2,400 in Manchester or Nashua.

Childcare, healthcare, and food costs run 5-15% lower in New Hampshire than in Massachusetts according to BLS regional CPI data, with the largest differentials in housing and healthcare. Massachusetts has the highest healthcare costs in the country, driven by the concentration of academic medical centers (Mass General, Brigham and Women's, Boston Children's) and the all-payer claims database regulations. New Hampshire's healthcare infrastructure is solid but more limited for specialized care, with many New Hampshire residents traveling to Boston for complex procedures. Both states support remote work, with broadband availability comparable in major metros but uneven in rural New Hampshire.

Remote work considerations

Massachusetts uses physical-presence sourcing for wage income, not the convenience-of-employer rule. A New Hampshire resident who teleworks from New Hampshire for a Massachusetts employer owes Massachusetts non-resident tax only on wages earned for work physically performed in Massachusetts — typically days commuting to the Boston or Cambridge office. A purely remote worker living in New Hampshire and never setting foot in Massachusetts owes no Massachusetts income tax. This makes the New Hampshire-Massachusetts arrangement particularly favorable for full-remote workers, who capture the full New Hampshire tax savings without Massachusetts convenience-rule exposure.

The reverse direction — a Massachusetts resident working remotely for a New Hampshire employer — produces Massachusetts tax on all wages, since Massachusetts taxes its residents on worldwide income under M.G.L. c.62, §1. The New Hampshire employer should register for Massachusetts income tax withholding and SUI if the Massachusetts-based employee performs all work there, and should file Form M-4 (the Massachusetts equivalent of the federal W-4) with the employer. A Massachusetts resident who fails to set up proper withholding will owe estimated tax plus underpayment penalties under M.G.L. c.62B, §9.

The Massachusetts residency audit is the most significant risk for movers. The Massachusetts Department of Revenue audits moves to no-tax states using the close-to-12 domicile factors in TIR 95-5, including driver license, voter registration, time-in-state, location of family, location of bank accounts and brokers, and where high-value personal property is kept. The 183-day statutory residency rule under M.G.L. c.62, §1(j) creates a separate trap: a New Hampshire domiciliary who maintains a permanent place of abode in Massachusetts and spends 183 days or more in Massachusetts is taxed as a full-year Massachusetts resident on all income. Taxpayers who keep a Massachusetts apartment "just in case" face elevated audit risk and frequently receive Form DOR-1 information document requests asking for proof of the move.

Quality of life factors

Massachusetts offers world-class universities (Harvard, MIT, Boston University, Boston College, Tufts), the largest academic medical center concentration in the country, and an unmatched innovation economy in biotechnology (Moderna, Vertex, Pfizer's Kendall Square operations), robotics (Boston Dynamics), and financial services (Fidelity, Wellington Management). The state's cultural infrastructure — museums, theaters, restaurants, professional sports — is exceptional. Trade-offs include the third-highest housing costs in the country, severe traffic congestion on Route 128 and I-93, and a regulatory environment that some find burdensome.

New Hampshire offers substantially lower housing costs, no income tax, no sales tax, and excellent access to outdoor recreation in the White Mountains, Lakes Region, and seacoast. The state's economy is anchored by defense contracting (BAE Systems, Raytheon in Nashua), high-tech manufacturing, and a growing technology sector in Manchester and Portsmouth. Trade-offs include the third-highest property taxes in the country, more limited healthcare infrastructure for complex cases, and a colder winter climate than coastal Massachusetts. The "Live Free or Die" state motto reflects a regulatory environment that some find appealing and others find thin on public services. Both states support remote work, with comparable broadband availability in major metros.

Which state wins for which type of remote worker

New Hampshire wins decisively for high-income remote workers above $150,000 in wage income, particularly those who can work fully remotely and avoid Massachusetts physical presence. The annual income tax savings at $500,000 exceeds $25,000, which funds a substantial housing upgrade in southern New Hampshire towns with shorter commutes to Boston. New Hampshire also wins for households facing the Massachusetts millionaire surtax, for business sellers looking to escape the 5.0% tax on capital gains, and for households seeking to reduce consumer goods sales tax exposure on major purchases.

Massachusetts wins for workers whose careers depend on physical presence in the Boston innovation economy — biotechnology, academic medicine, venture capital — sectors where in-person collaboration drives compensation and advancement. Massachusetts also wins for households who value urban density, walkable neighborhoods, and access to specific cultural institutions. The convenience rule is not a factor in this pairing (Massachusetts does not enforce it), so the decision turns primarily on income level, lifestyle preference, and willingness to commute. For households with children approaching college age, the Massachusetts public university system (UMass Amherst, UMass Boston) and the substantial in-state tuition discount for residents can offset the income tax differential.

Common mistakes when choosing between these two states

The most common mistake is comparing only income tax rates without modeling property tax differences. New Hampshire's 1.77% effective property tax rate is the third-highest in the country and can add $4,500+ annually for a typical $700,000 home. The mistake cuts the other direction too: a Massachusetts resident moving to New Hampshire may be surprised by the property tax bill on a comparable home, partially offsetting the income tax savings at lower income levels. The second mistake is keeping a Massachusetts residence "just in case" — the 183-day statutory residency rule under M.G.L. c.62, §1(j) catches many snowbirds who maintain a Massachusetts apartment and visit frequently.

The third mistake is assuming the Massachusetts PFML is negligible — at $200,000 of wages, the 0.66% PFML contribution is approximately $1,320 annually, comparable to a moderate health insurance premium. The fourth mistake is overlooking the Massachusetts estate tax exposure. With a $2 million exemption (one of the lowest in the country), a household with a $3 million estate faces approximately $135,000 in Massachusetts estate tax, while New Hampshire estate tax is $0. The fifth mistake is assuming the New Hampshire PFML program (beginning 2026) is mandatory — the program is voluntary for most workers, with an opt-in mechanism that allows workers to decline coverage and avoid the payroll contribution.

What to do next

Run your numbers through our multi-state withholding calculator using your actual wage income, expected housing costs, and current state of residence. The calculator handles Massachusetts's flat 5.0% rate, millionaire surtax above $1M, PFML premium, and New Hampshire's zero-tax structure. If you are seriously considering a move to New Hampshire, document the domicile factors from Massachusetts TIR 95-5 before the move — change your driver license, voter registration, vehicle registration, banking, and healthcare providers on or before the move date. Keep a contemporaneous day-count log to prove fewer than 183 Massachusetts days if you maintain a Massachusetts residence. Confirm with the Massachusetts employer in writing whether remote work is permitted from New Hampshire, and ensure the payroll system withholds New Hampshire tax (zero) rather than Massachusetts tax once the move is complete. Consult a licensed CPA who handles MA-NH cross-border matters before triggering a high-income relocation.
