Frequently Asked Questions

What is the Massachusetts state income tax rate for 2026?

Massachusetts has a flat income tax rate of 5% on most income for 2026. The state also imposes a 4% surtax on taxable income above $1,083,150, bringing the effective top rate to 9% for high-income earners. This surtax, known as the millionaire's tax, was approved by voters in 2022.

What is the personal exemption in Massachusetts?

Massachusetts offers a personal exemption of $4,400 for single filers and $8,800 for married filing jointly. This exemption is subtracted from your gross income (after pre-tax deductions) before the 5% state tax rate is applied. There is no standard deduction in Massachusetts, only the personal exemption.

Does Massachusetts have local income taxes?

No, Massachusetts does not impose local or county income taxes on wages. However, Massachusetts does require employers and employees to contribute to the Paid Family and Medical Leave (PFML) program, which is not included in this calculator estimate.

How does pay frequency affect my Massachusetts tax withholding?

Your total annual tax liability depends on your annual income, not how often you are paid. Changing from biweekly to monthly simply divides the same annual take-home into fewer, larger payments. Annual totals remain the same regardless of pay frequency.

Does Massachusetts tax Social Security and retirement income?

Massachusetts does not tax Social Security benefits. Additionally, Massachusetts offers a deduction for up to $2,000 in interest and dividend income and allows certain pension and annuity income to be excluded for seniors. Up to $15,000 of qualifying pension income may be exempt for taxpayers aged 65 or older.
