Yes, Massachusetts charges state income tax on wages, investment income, and other earnings
Massachusetts has a state income tax. The tax rate is a flat 5.0% on most types of income, though certain capital gains are taxed at a higher rate. This means if you earn money in Massachusetts or live there, you will owe state income tax in addition to federal income tax.
The state collects income tax through payroll withholding if you are employed, or through quarterly estimated tax payments if you are self-employed or have investment income. Massachusetts also taxes retirement income, including distributions from IRAs and 401(k)s, though there are some exemptions for certain types of retirement accounts and income sources.
Key Takeaways
- Massachusetts taxes most income at a flat rate of 5.0%, with some capital gains taxed at 5.25%.
- If you work in Massachusetts, your employer will withhold state income tax from your paycheck automatically.
- Self-employed people and those with investment income must make quarterly estimated tax payments to avoid penalties.
- Certain types of retirement income, including Social Security benefits, are exempt from Massachusetts state income tax.
- You file Massachusetts state taxes using Form 1, the state's equivalent to the federal 1040.
How the 5.0% tax rate applies to different types of income
The standard Massachusetts income tax rate of 5.0% applies to wages, salaries, tips, and most other earned income. It also applies to interest, dividends, and rental income. This is a flat tax, meaning everyone pays the same percentage regardless of how much they earn—there are no tax brackets that increase with income the way the federal system does.
Capital gains—profit from selling stocks, real estate, or other investments held for more than one year—are taxed at 5.0% if the gain is under $100,000. Gains above $100,000 are taxed at 5.25%. This higher rate on large capital gains took effect in 2023 and applies only to gains that exceed that threshold in a single tax year.
Some income is not taxed at all in Massachusetts. Social Security benefits are fully exempt. Certain retirement distributions, including those from IRAs and 401(k)s, are also exempt if you meet age and other requirements. The state publishes a detailed list of exempt income types on the Massachusetts Department of Revenue website.
How withholding works if you are employed
When you start a job in Massachusetts, you will fill out a Form MW-4 (the state withholding form) to tell your employer how much state income tax to deduct from each paycheck. Your employer then sends that withheld amount to the Massachusetts Department of Revenue on your behalf.
The amount withheld depends on your filing status, the number of dependents you claim, and your expected annual income. If you have multiple jobs, work part-time, or have a spouse who also works, you may need to adjust your withholding to avoid owing money at tax time or overpaying and getting a refund.
You can change your withholding at any time by submitting a new Form MW-4 to your employer. This is useful if your life circumstances change—for example, if you get married, have a child, or take on a second job. The form is available on the Massachusetts Department of Revenue website.
Self-employment and estimated tax payments
If you are self-employed, own a business, or have significant investment income, you likely owe quarterly estimated tax payments to Massachusetts. These are payments you make four times a year (usually in April, June, September, and January) to cover the state income tax on income that is not subject to withholding.
You calculate estimated payments based on your expected income for the year. If you underestimate and owe more than $400 at tax time, you may face a penalty. If you overestimate, you will receive a refund when you file your annual return. Many self-employed people use their prior year's tax return as a guide to calculate the current year's payments.
The Massachusetts Department of Revenue provides a worksheet and instructions for calculating estimated payments on its website. You can pay online through their payment portal, by mail, or through an authorized payment processor.
Filing your Massachusetts state tax return
Massachusetts residents and anyone who earned income in the state must file a state tax return if their income exceeds the filing threshold. For 2024, the threshold varies by age and filing status but is generally around $15,000 for single filers under 65 and higher for those 65 and older or filing as married.
You file using Form 1, which is Massachusetts's main income tax return form. You can file on paper by mailing it to the Department of Revenue, or you can file electronically through the state's online system or through tax software that supports Massachusetts returns. E-filing is faster and reduces the chance of errors.
Your state return is due on the same date as your federal return—typically April 15. If you file for a federal extension, you automatically receive an extension for your state return as well. You can request an extension online through the Department of Revenue website.
Tax credits and deductions available in Massachusetts
Massachusetts offers several tax credits that can reduce the amount of state income tax you owe. The Earned Income Tax Credit (EITC) is available to low- and moderate-income workers and is calculated as a percentage of the federal EITC. The state also offers a child and dependent care credit, a property tax credit for renters and homeowners, and credits for education expenses.
Unlike the federal system, Massachusetts does not allow a standard deduction. Instead, you claim a personal exemption of $4,400 per person (for 2024, though this amount adjusts annually). You also claim exemptions for dependents. These exemptions reduce your taxable income before the 5.0% tax is applied.
If you pay property taxes or rent in Massachusetts, you may be able to claim a property tax credit. Seniors and disabled people may also may have access to for additional credits. The Department of Revenue website lists all available credits and the forms needed to claim them.
What happens if you move to or from Massachusetts
If you move to Massachusetts during the year, you owe state income tax only on income earned while you were a resident. If you move away, you owe tax only on income earned before you left. You will need to file a part-year resident return and provide documentation of your move date, such as a lease, utility bill, or moving company records.
If you worked in Massachusetts but lived in another state, you may owe Massachusetts tax on that income even if you did not live there. However, most states have reciprocal agreements to prevent double taxation. You can claim a credit on your home state's return for taxes paid to Massachusetts. The specifics depend on which state you lived in.
Frequently Asked Questions
Do I have to file a Massachusetts tax return if I only worked there part of the year?
You must file if your income exceeds the filing threshold for your age and status, regardless of how long you worked. If you were a part-year resident, you file a part-year return and owe tax only on income earned while you lived in Massachusetts. Bring documentation of when you moved, such as a lease or utility bill.
Is Social Security taxed in Massachusetts?
No. Social Security benefits are fully exempt from Massachusetts state income tax. You do not need to report them on your state return, though you may need to report them on your federal return depending on your total income.
What if I did not have enough tax withheld and owe money?
You can pay the balance when you file your return. If you owe more than $400, you may face a penalty and interest. To avoid this next year, adjust your Form MW-4 with your employer to increase withholding, or make quarterly estimated payments if you are self-employed.
Can I file my Massachusetts return electronically?
Yes. You can file through the state's online system, through tax software that supports Massachusetts, or by mail. E-filing is faster and the state recommends it. You will need your Social Security number and prior year's return information to file online.
Do I owe Massachusetts tax on income from other states?
Generally, no. You owe Massachusetts tax only on income earned in the state or if you are a resident. If you lived in another state and worked there, you owe tax to that state instead. However, if you are a Massachusetts resident, you may owe tax on income earned anywhere, depending on the source.
