How Your Massachusetts Paycheck Works

Federal Income Tax
Calculated using 2025 federal brackets from 10% to 37%, applied to your taxable income after the standard deduction.
Social Security
6.2% of your gross pay up to $176,100. Funds the Social Security retirement and disability program.
Medicare
1.45% of all gross pay with no income cap. High earners over $200K pay an additional 0.9% surtax.
Massachusetts State Tax
Massachusetts taxes wages at 5.0% after a personal exemption of $4,400 (single) or $8,800 (MFJ). High earners above $1M face an additional 4% surtax.
