Standard employees with Massachusetts withholding on their paychecks
How much Massachusetts tax will you pay?
Massachusetts uses a flat tax rate of 5% on most income, making it one of the easiest state taxes to calculate. Unlike states with progressive brackets, nearly everyone pays the same 5% rate regardless of income level or filing status.
The simple math
For most employees, the calculation is straightforward:
Annual MA tax = (Taxable income) × 5%
This applies to wages, salaries, bonuses, and most other income types. The only major exception is the 4% surtax on income over $1 million (so ultra-high earners pay 9% on income above $1M).
Real-world examples by salary level
How withholding appears on your paycheck
Your Massachusetts withholding depends on:
According to the Massachusetts Department of Revenue withholding tables, employers calculate this by taking your gross pay, subtracting pre-tax deductions (401k, health insurance, etc.), then applying the 5% rate to the remaining amount.
Example: $75,000 salary detailed breakdown
Let's walk through a typical biweekly paycheck:
This matches our annual calculation: $75,000 × 5% = $3,750 ÷ 26 pay periods = $144 (small difference due to rounding).
Special situations to know about
Massachusetts vs. other states
The 5% flat rate makes Massachusetts relatively straightforward compared to progressive systems. For middle-income earners, it's often more expensive than states like New Hampshire (no income tax) but less than high-tax states like California or New York for equivalent income levels.
What you should do
Check your paystub to verify your MA withholding matches 5% of your taxable income. If you consistently get large refunds or owe money, adjust your M-4 form with HR. The flat rate system means there's less complexity in getting withholding right compared to progressive tax states.
Key takeaway: Massachusetts' 5% flat tax is simple to calculate - just multiply your taxable income by 5%. A $75,000 earner pays exactly $3,750 annually, or about $144 per biweekly paycheck.
