How to Use Massachusetts Income Tax Calculator Online
Individual income tax in the Commonwealth of Massachusetts is administered by the Massachusetts Department of Revenue (MassDOR). Massachusetts operates primarily on a flat 5.00% individual income tax rate on earned wages, interest, and ordinary income, supplemented by a constitutional 4.00% Fair Share Amendment ('Millionaires Tax') surtax on taxable income exceeding $1,000,000 (creating a 9.00% top marginal rate). Furthermore, Massachusetts employees contribute 0.46% toward Paid Family and Medical Leave (MA PFML).

1. Massachusetts 5.00% Flat Tax & The 4.00% Millionaires Surtax
Massachusetts uses a flat base individual income tax rate of 5.00% on Part B taxable income (wages, salaries, tips, and trade or business income). In November 2022, Massachusetts voters approved Question 1 (the Fair Share Amendment), creating a multi-tiered system for high-income earners:
- 5.00% Base Flat Rate: Applies to all taxable income up to $1,000,000 (adjusted annually for inflation).
- 4.00% Fair Share Surtax: Applies exclusively to taxable income exceeding $1,000,000 (indexed to ~$1,053,750 in 2024 and ~$1,083,150 in 2025/2026).
- 9.00% Combined Top Marginal Rate: Dollars earned above the $1M threshold face a combined state rate of 9.00%, dedicated by law to education and transportation projects.
- Marginal Application: Earning over $1M does not increase the tax rate on your first $1,000,000 of income.
2. Massachusetts Paid Family and Medical Leave (MA PFML) Contributions
Under the Massachusetts Paid Family and Medical Leave program (M.G.L. c. 175M), covered Massachusetts employees contribute to the state PFML Trust Fund through mandatory payroll withholdings:
- Total Employee Contribution: 0.46% of eligible wages for employers with 25 or more workers (split between medical leave at 0.18% and family leave at 0.28%).
- Wage Cap Limit: Subject to the annual Social Security wage base cap ($176,100 in 2025; $168,600 in 2024). Earnings above the cap are exempt from PFML deductions.
- Benefit Protection: Provides up to 26 weeks of paid leave per benefit year for eligible medical or family caregiving needs.
3. Personal Exemptions, Child & Family Credits, and Renter Deductions
Massachusetts offers valuable statutory exemptions and deductions that directly reduce state taxable income on Form 1:

- Short-Term Capital Gains (8.50%): Under Chapter 177, Massachusetts reduced the tax rate on short-term gains (held 1 year or less) from 12.00% to 8.50%, making Massachusetts more competitive for active investors and trading activities.
