Massachusetts Paycheck Calculator
Massachusetts taxes wages at a flat 5%, softens it with exemptions that depend on your filing status, and — since 2023 — adds a 4% surtax on income above an inflation-indexed line that sits at $1,107,750 for 2026. This calculator applies all three.

Flat, with a ceiling that is not flat
The Massachusetts wage rate has been 5.00% since 2020. What changed in 2023 is the top: a constitutional amendment added a 4% surtax on the slice of taxable income above an annually indexed threshold — $1,107,750 for 2026, up from $1,083,150 in 2025. Only the excess pays 9%; the first $1.1 million pays 5% no matter what. For the overwhelming majority of paychecks the surtax line in this calculator will read zero, and it is shown separately when it does not.
Instead of a standard deduction, Massachusetts subtracts a personal exemption that depends on filing status — $4,400 single or married filing separately, $6,800 head of household, $8,800 married filing jointly — plus $1,000 per dependent. Head of household is its own figure here, not a multiple of the single one, which is why this page asks for filing status rather than assuming it.
What reduces Massachusetts wages
401(k) deferrals, Section 125 premiums, and HSA contributions all reduce state wages, matching federal treatment. At filing time Massachusetts also lets you deduct the Social Security and Medicare tax you paid, up to $2,000 per earner — a quiet deduction worth up to $100 that this paycheck-level estimate notes but does not apply. Short-term capital gains face 8.5% and long-term collectible gains 12%, but neither touches a wage paycheck.

Withholding versus this estimate
Employer withholding follows Circular M and your Form M-4, and for 2026 the Circular M tables build the surtax into withholding for very high earners — so a large RSU vest or bonus can trigger surtax-level withholding even in a year you end below the threshold; filing settles it. The Paid Family and Medical Leave contribution is a real Massachusetts paycheck line this calculator omits, because its 2026 rate was not verified against the Department of Family and Medical Leave at the time of review — expect roughly half a percent of wages there.

Frequently asked questions
Does the millionaire surtax affect me if I earn well under $1 million?
No. The 4% applies only to taxable income above $1,107,750 in 2026, and only to the excess. Below the line your rate is 5% flat. The threshold is indexed to inflation each year, so it drifts upward rather than catching more people over time.
Why does Massachusetts ask my filing status if the rate is flat?
Because the exemption is not flat: $4,400 single, $6,800 head of household, $8,800 joint. At 5%, filing jointly instead of singly is worth $220 a year in exemption relief, and head of household sits in between — the status changes the base, not the rate.
Can a big bonus push one paycheck into the surtax?
Withholding, yes; liability, no. The 2026 Circular M has employers withhold the extra 4% when annualized supplemental pay crosses the threshold, so the check may be light. Whether you actually owe surtax depends on the whole year's taxable income when you file.
What is the PFML line on my actual pay stub?
Your share of the Paid Family and Medical Leave contribution, which funds the state's leave benefits. This calculator leaves it out because its 2026 rate was not verified at review time; it has recently run on the order of half a percent of wages up to the Social Security wage base.
Is anything about my paycheck different in Boston versus the rest of the state?
No — Massachusetts has no local income taxes, so a Boston paycheck and a Worcester paycheck carry identical state lines. Local variation shows up in property tax bills, not pay stubs.
