About the Massachusetts Income Tax Calculator
The Massachusetts Income Tax Calculator gives you an instant answer from just a few inputs — filing status, gross annual income, pre-tax deductions (401(k), hsa, premiums). It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
Massachusetts runs a progressive income tax with 2 brackets, starting at 5% on the first $1,083,150 of taxable income and topping out at 9% on income above $1,083,150 for a single filer. As with federal tax, each rate applies only to the slice of income inside its own bracket — reaching the top rate does not retroactively tax your earlier dollars at that rate, which is why the effective rate this calculator reports always lands below your marginal rate. Before any of those rates apply, Massachusetts subtracts a standard deduction of $4,400 for single filers and $8,800 for joint filers. Note that Massachusetts does not widen its brackets for married couples filing jointly — the same thresholds apply regardless of filing status, which produces a marriage penalty for two-earner households. This estimate covers state income tax, federal income tax, and FICA on wage income using 2026 figures. It does not model city or county income taxes, tax credits, itemized deductions, self-employment income, or part-year residency — if you moved into or out of Massachusetts during the year you will generally file a part-year return and allocate income between states rather than paying full-year tax to either. Treat the result as a planning estimate and confirm anything you file with the Massachusetts tax authority or a qualified tax professional.
