How Massachusetts taxes a paycheck in 2026
Massachusetts taxes wages at a flat 5%. Flat 5% plus a 4% "millionaires tax" surtax on income above ~$1.08M (2026, indexed). On $100,000 (single), the 2026 math: federal $13,170, state $4,775, FICA $7,650 – leaving $74,405 net, or $6,200 per month.
Federal numbers use the 2026 standard deduction of $16,100 and the current bracket schedule. Pre-tax 401(k) and health premiums reduce these figures further – model them in the calculator above.
How the 4% surtax actually applies
Massachusetts adds a 4% surtax on taxable income above ~$1,083,000 in 2026 (indexed annually), on top of the 5% flat rate – a 9% marginal rate at the top. The surtax applies only to the dollars above the threshold.
One-time events are the trap: selling a business or home with a large gain can cross the line in a single year. Installment sales and gain timing are the standard mitigations – worth professional advice well before the transaction.
Affordability: what that net pay buys here
Against Massachusetts's typical one-bedroom rent of $2,400, a net of $74,405 leaves $45,605 per year after housing – a comfortable margin by national standards. The state's cost index is 127 (US = 100).
