MassachusettsSalary Calculator 2026 — Take-Home Pay After Federal & State Taxes

Massachusetts has a flat 5% income tax on most income, but in 2023 added a 4% surtax (the 'Fair Share Amendment') on income above $1 million, creating an effective 9% top rate for high earners. For the vast majority of workers earning under $1 million, the rate is a straightforward 5%. Massachusetts does not fully conform to the federal standard deduction — it uses its own deduction calculations. The state exempts short-term capital gains at 12% and has different treatment for long-term gains. No cities in Massachusetts levy local income taxes. Massachusetts has above-average property taxes and a strong economy anchored by healthcare, education, and technology. Boston residents pay no city income tax. The 5% flat rate is predictable for mid-income earners but the healthcare and housing costs in Greater Boston significantly affect real take-home purchasing power.
