Massachusetts is one of the most expensive U.S. states, ranking consistently in the top five for cost of living.
The state's index is approximately 130 to 140 (U.S. average = 100), driven primarily by exceptionally high housing costs in the Greater Boston area.
The state's world-class universities, biotech and life sciences industry, and financial services sector attract a highly educated and well-paid workforce, which in turn drives up costs.
Areas outside Boston — western Massachusetts (Springfield, Pittsfield), Cape Cod in off-season — are considerably more affordable.
Massachusetts is often compared to the cost of living in Connecticut, the cost of living in New Jersey, and the cost of living in New York — all expensive Northeastern states.
Those choosing Massachusetts should review 2026 cost of living increases and their average net worth by age to ensure their finances are positioned for one of the country's highest-cost environments.
Housing Costs in Massachusetts
Boston and its inner suburbs have some of the highest housing costs in the U.S. Median home prices in Boston proper exceed $700,000. Cambridge, Brookline, and Newton median prices approach $900,000 to $1.2 million. Even outer suburbs like Framingham and Lowell have median home prices above $450,000.
Western Massachusetts (Springfield, Northampton) offers significantly lower prices of $250,000 to $350,000.
Anyone purchasing in Massachusetts should carefully assess how much house you can afford at these price points, and understand how mortgage amortization works on large loan balances.
The average mortgage payment in the Boston metro is among the highest in the country.
The mortgage interest deduction provides some relief for high-balance Massachusetts mortgages, and homeowners insurance tax rules are worth reviewing for high-value properties. Renters should model their budget using affordable rent thresholds before committing to Boston-area rents.
Taxes in Massachusetts
Massachusetts has a 5% flat state income tax for most income. However, a 4% millionaire's surtax (Proposition 80) took effect January 1, 2023, applying to annual income above $1 million — making Massachusetts's effective top rate 9% for high earners. The state sales tax is 6.25%.
Massachusetts has no county-level income tax. Property taxes are moderate by state standards despite high property values.
Healthcare — Universal Coverage
Massachusetts was the first state to implement near-universal health insurance coverage with the 2006 Massachusetts Health Care Reform Act (Chapter 58), which served as the model for the ACA.
Residents who can afford health insurance must have it or face a state tax penalty.
Coverage is available through employers, the Massachusetts Health Connector (state marketplace), or MassHealth (Medicaid).
Massachusetts healthcare costs are among the highest in the nation.
Biotech and Education Economy
The Greater Boston area is one of the world's premier biotech and life sciences clusters. Major employers include Biogen, Moderna, Genzyme, and numerous smaller biotech companies. Harvard, MIT, Tufts, Boston University, and Boston College are major institutions.
The concentration of high-paying research, technology, and financial services jobs supports high wages and, in turn, high prices.
Workers in Massachusetts's dominant industries should benchmark their pay using the software engineer salary, pharmacist salary, and financial analyst salary guides.
Healthcare professionals should review the physician salary and registered nurse salary data.
All high-income Massachusetts workers benefit from strong salary negotiation skills and maximizing 401(k) contributions and Roth IRA savings given the state's high cost environment.
