Massachusetts Paycheck Calculator

Paycheck taxes in Massachusetts

Massachusetts taxes most income at a flat 5%, but the voter-approved 4% ‘Fair Share’ surtax applies to taxable income above $1,107,750 for 2026 — an effective 9% top rate. The threshold is inflation-indexed and identical for every filing status, so unlike most states a married couple gets no wider band than a single filer; it has climbed from $1,053,750 in 2024 to $1,083,150 in 2025 and $1,107,750 now. There is no standard deduction; each filer instead gets a $4,400 personal exemption ($8,800 joint).

Bonuses and supplemental wages in Massachusetts

Bonuses and other supplemental wages are frequently withheld differently from regular pay, and states set their own rules. This calculator applies Massachusetts's regular withholding to every dollar and does not model a separate supplemental rate, so a bonus paycheck can come out higher or lower than the figure above. Federal supplemental withholding is a flat 22% up to $1 million; for Massachusetts's own treatment, check the state authority linked below.

For the federal half, which this site does model, compare what withholding takes from a bonus against what you actually owe — the 22% flat rate is withholding, not a tax bill, and the difference comes back at filing.

Massachusetts vs. its neighbors

On a $100,000 salary you keep $74,400 in Massachusetts — $4,780 less than in neighboring New Hampshire, $80 more than in New York, and $30 less than in Connecticut.

Federal income tax and FICA are identical in every state, so the whole gap above is state income tax. Single filer, $100,000 of wages, no 401(k) or other pre-tax deductions, 2025 state tables. Local income taxes (city and county) are not included. Run your own salary through the calculator above, or on any state's page.

Neighbours are only part of the picture. The study behind these figures ranks what a $100,000 salary takes home in all 50 states, with Massachusetts's row in place — the entire spread between best and worst is state income tax, since federal tax and FICA are identical everywhere.

A worked example at Massachusetts's median income

Massachusetts's median household income is $113,900 (2024, U.S. Census Bureau via FRED (real median household income)). Run through the same engine as the calculator above (single filer, taxes only):

That is an effective all-in tax rate of 26.7% at the median — your own number depends on filing status, 401(k), and benefits. Enter your salary above for the exact figure.
