How Massachusetts Taxes Work in 2026
Massachusetts levies a flat state income tax rate of 5.00% on all taxable income. A flat tax means every taxpayer pays the same percentage, regardless of income level, which simplifies tax filing. Massachusetts offers a standard deduction of $0 for single filers and $0 for married filing jointly. This deduction reduces your taxable income before the 5.00% rate is applied. In addition to the 5.00% state income tax, Massachusetts residents also pay federal income tax (10% to 37% based on income) and FICA taxes (6.2% Social Security + 1.45% Medicare).
