Massachusetts Take-Home Pay Calculator
Estimate your Massachusetts paycheck using MA's flat 5% state income tax rate — plus the 4% "Millionaires Tax" surtax for very high earners — and federal income tax and FICA.
What comes out of a Massachusetts paycheck
Massachusetts taxes most income at a flat 5%. On top of that, voters approved a constitutional amendment in 2022 adding a 4% surtax — the "Millionaires Tax" — on annual taxable income above an inflation-adjusted threshold ($1,083,150 for 2025). Only the portion of income above that line is taxed at the extra 4%; the rest is still taxed at the standard 5%. For the overwhelming majority of Massachusetts workers, this calculator's 5% flat rate is the whole story.
MA-taxable income: $80,000 − $4,000 pre-tax − $4,400 personal exemption = $71,600. MA tax: $71,600 × 5% = $3,580 (well below the surtax threshold, so no additional 4% applies).
Federal tax (on $61,000 taxable) ≈ $8,334 · MA state tax ≈ $3,580 · Social Security $4,960 · Medicare $1,160.
Annual take-home ≈ $57,966 → about $2,229 per biweekly paycheck (72.5% of gross).
How the "Millionaires Tax" actually works
The 4% surtax only applies to the slice of taxable income above the yearly threshold — it's a true marginal addition, not a rate that applies to your whole income once you cross the line. A taxpayer with $1,200,000 in taxable income for 2025 would pay the standard 5% on the first $1,083,150, then an additional 4% (9% total) only on the remaining roughly $117,000. The threshold rises each year with inflation — it was $1,083,150 for 2025 and rises to $1,107,750 for 2026.
Common mistakes when estimating Massachusetts take-home pay
- Applying the 4% surtax to all income once triggered. It only applies to the amount above the threshold, not the entire taxable income.
- Worrying about the surtax at typical income levels. It affects only taxpayers above roughly $1.08 million in taxable income — a small fraction of filers.
- Confusing Massachusetts's personal exemption with a standard deduction. It's a smaller, fixed per-filer amount rather than a large standard deduction.
