Estimates using federal brackets, FICA and your state rate. Not tax advice.
Massachusetts uses a flat 5 percent income tax rate on wages for 2026. Unlike graduated states, the same 5 percent rate applies to all taxable wage income from the first dollar through the upper six figures. Above approximately $1.08 million in annual income, Massachusetts adds a 4 percent surtax under the so-called Fair Share Amendment approved by voters in 2022, bringing the effective top rate to 9 percent for very high earners. For the vast majority of Massachusetts workers, the 5 percent flat rate is the only state income tax they pay.
On a $65,000 salary, Massachusetts state income tax is about $3,250 per year. Massachusetts allows a personal exemption and certain deductions that can reduce taxable income slightly, so your actual withholding may come in a bit below that estimate depending on your filing status. The $1.08 million surtax threshold does not affect workers at this income level.
Massachusetts does not impose a local income tax at the city or county level, so Boston residents and workers in smaller towns all pay the same statewide 5 percent rate with no municipal add-on. The calculator covers federal income tax brackets, FICA (Social Security and Medicare), and the Massachusetts flat rate, which you can adjust for your situation. Results are estimates, not tax advice.

No. Massachusetts does not allow cities or towns to levy a local income tax on wages, so all residents pay only the statewide 5 percent flat rate regardless of where they live or work within the state.
