Massachusetts Paycheck Calculator
Massachusetts has a flat income tax rate of 5.0% on most income. Starting in 2023, an additional 4% surtax applies to income over $1 million (the "millionaire tax"), effectively creating a 9% rate on income above that threshold. The state uses personal exemptions rather than a standard deduction.
