How Massachusetts taxes your paycheck
Massachusetts applies a flat 5% income tax to wage income up to about $1.08 million for 2026, then adds a 4% 'millionaire surtax' on income above that threshold — bringing the top marginal rate to 9% at the very highest incomes. After a personal exemption of about $4,400 for a single filer, the calculator above applies the 5% rate to estimate the Massachusetts income tax withheld from your typical pay.
For the overwhelming majority of workers, Massachusetts is effectively a clean flat-5% state, since the 4% surtax only touches earnings past roughly $1.08 million. That surtax is what turns the old nickname 'Taxachusetts' into something closer to a two-tier system: flat and moderate for most, sharply higher only at the top.
The millionaire surtax and no local add-on
The 4% surtax stacks on top of the base 5% only for the slice of income above about $1.08 million, so a high earner's marginal rate reaches 9% while their effective rate stays lower. No Massachusetts city or town taxes wages, so for most people the flat 5% state rate plus federal tax and FICA is the full picture, with no municipal income tax added on.
