Does Massachusetts have an estate tax? Yes, it does. Massachusetts is one of about a dozen states with its own estate tax, separate from the federal one. If you are planning ahead, this matters more than many people expect.
The state limit is much lower than the federal limit. As a result, families who would never owe federal estate tax can still owe Massachusetts estate tax. A paid-off home, a retirement account, and life insurance can add up fast. If you are settling a loved one’s estate right now, take a breath. This guide walks through the rules in plain English, one step at a time.
Does Massachusetts Have an Estate Tax in 2026? The Short Answer
Yes. In 2026, Massachusetts taxes estates worth more than $2 million. An estate is everything a person owned when they died. That includes the home, bank accounts, investments, retirement accounts, and often life insurance. The tax comes out of the estate before the heirs get their shares. The heirs do not pay it out of their own pockets.
The $2 million limit comes from Chapter 50 of the Acts of 2023, a state tax relief law. It doubled the old $1 million limit. It applies to anyone who died on or after January 1, 2023. The rules are in Massachusetts General Laws Chapter 65C, the state’s estate tax law.
The 2023 law also fixed the old “cliff.” Before the change, an estate just over $1 million could owe tax on the whole amount. Now the law gives every estate a credit of $99,600. In most cases, that credit means the first $2 million is never taxed at all.
Massachusetts Estate Tax Rules and Key Figures
Here are the main numbers to know. Keep in mind that the state figure is fixed by law. Typically, it does not rise with inflation each year like the federal limit does.
| Rule | Massachusetts | Federal (2026) |
|---|---|---|
| Exemption amount | $2,000,000 | $15,000,000 per person |
| Top tax rate | 16% | 40% |
| Indexed for inflation? | No | Yes |
| Unused exemption passes to spouse? | No | Yes (called “portability”) |
| Tax return | Form M-706 | Form 706 |
| Return and payment due | 9 months after death | 9 months after death |
| Inheritance tax? | No | No |
The tax uses graduated rates. That means the rate climbs as the estate grows, topping out at 16%. However, only the part above $2 million is actually taxed. For example, an estate worth $2.3 million owes tax tied to the extra $300,000, not to the full $2.3 million.
One rule surprises many married couples. Massachusetts has no “portability.” Portability lets a surviving spouse use whatever exemption the first spouse did not use. The federal system allows it, but Massachusetts does not. As a result, if the first spouse leaves everything to the other, that first $2 million exemption can be lost.
So, does Massachusetts have an estate tax for people who live elsewhere? Sometimes. A non-resident who owns Massachusetts real estate, like a Cape Cod cottage, may owe tax on that property. The 2023 law also made clear that a Massachusetts resident’s out-of-state real estate is left out of the state tax math.
What to Do Next If You Are Planning or Settling an Estate
If you are planning ahead, start with a simple list. Write down your home value, savings, investments, retirement accounts, and life insurance amounts. Many people are surprised to land near the $2 million line. If you are close, you may be able to lower the future tax with planning.
For example, many married couples use a “credit shelter trust.” This is a trust that holds assets up to the first spouse’s $2 million exemption. Because of this, that exemption is not wasted. A licensed Massachusetts estate planning attorney can explain whether this fits your family.

If you are an executor settling an estate, the timing matters most. An executor is the person named in a will to wrap up someone’s affairs. In most cases, Form M-706 and any tax due must reach the Massachusetts Department of Revenue within 9 months of the death. An extension to file may be possible. However, interest can still build on unpaid tax. Check the Massachusetts Department of Revenue website or ask a licensed attorney or tax professional for help.
Finally, remember that estate tax and probate are not the same thing. Probate is the court process that confirms a will and moves property to heirs. An estate can owe tax even if it skips probate, such as when assets sit in a trust. When people ask, “does Massachusetts have an estate tax on trust assets?” the answer is often yes, because those assets still count toward the $2 million total.
Frequently Asked Questions
Does Massachusetts have an estate tax and an inheritance tax?
No, only an estate tax. Massachusetts does not have an inheritance tax. As a result, people who inherit generally do not pay state tax just for receiving money or property.
Is the whole estate taxed if it is over $2 million?
No. Since the 2023 law change, the $99,600 credit protects the first $2 million. Typically, only the amount above $2 million is taxed, at graduated rates up to 16%.
Do I need to file a Massachusetts estate tax return if no tax is owed?
In most cases, a Form M-706 is only required when the estate is worth more than $2 million. However, the rules for counting lifetime gifts and certain assets can be tricky. If the estate is close to the line, check with the Department of Revenue or a licensed professional.
Make Sure Your Plan Actually Works
A will or trust only does its job if the rest of your plan lines up. Two quick checks before you finish:
- Get your state’s exact rules — witnesses, notary, probate cost, and tax thresholds vary by state.
- Beneficiary forms beat your will — make sure your life-insurance beneficiaries are current, because named beneficiaries pass outside your will.
