How Are Bonuses Taxed in Massachusetts in 2025?
Bonuses in Massachusetts face both federal and state taxes, but the methods differ. The IRS treats bonuses as supplemental income, while Massachusetts uses the aggregate method. This section explains the basics.
Federal Tax on Bonuses
The IRS applies a flat rate to supplemental income:
- 22% for bonuses up to $1 million.
- 37% for amounts exceeding $1 million.
- Social Security (6.2%) and Medicare (1.45%) also apply, with thresholds adjusting for 2025.
Massachusetts State Tax on Bonuses
Massachusetts uses the aggregate method:
- Combines your bonus with annual income.
- Taxes the total at a flat 5% rate.
- Adds a 4% surtax if total income exceeds $1,053,750 (adjusted for inflation from 2023’s $1 million).
Example: A $5,000 bonus with a $60,000 salary totals $65,000. The state tax on $65,000 is $3,250 (5%), but you subtract the tax on $60,000 ($3,000), leaving $250 as the bonus tax.

How to Calculate Your Massachusetts Bonus Tax for 2025
Calculating your bonus tax involves a step-by-step process. This section provides a clear method.
Step-by-Step Calculation
- Determine Gross Bonus: Start with your bonus amount (e.g., $10,000).
- Add Annual Income: Combine with your yearly salary (e.g., $80,000 = $90,000 total).
- Apply State Tax: Multiply total income by 5% ($90,000 × 0.05 = $4,500). Subtract tax on salary alone ($80,000 × 0.05 = $4,000). Bonus state tax = $500.
- Federal Tax: Multiply bonus by 22% ($10,000 × 0.22 = $2,200).
- Social Security: If under $176,100, apply 6.2% ($10,000 × 0.062 = $620).
- Medicare: Apply 1.45% ($10,000 × 0.0145 = $145).
- Net Bonus: Subtract all taxes from gross ($10,000 – $500 – $2,200 – $620 – $145 = $6,535).
