Does Massachusetts Have an Estate Tax?
Whether Massachusetts levies its own estate tax, the exemption threshold that decides if an estate owes anything, and what a surviving spouse inherits tax-free. Estate tax is separate from any inheritance tax. Cited to the statute.
How the estate tax works in Massachusetts
The exemption threshold, how the tax applies only to value above it, and the transfers the law leaves untaxed.
| How the tax works | What it means |
|---|---|
| The estate pays, above a $2,000,000 threshold | Massachusetts taxes the estate itself, not the heirs. For deaths on or after January 1, 2023, no tax is due if the estate is worth $2,000,000 or less. Above that figure the estate files and may owe tax. |
| A credit means only the amount over $2,000,000 is taxed | The law gives a credit of up to $99,600 against the tax. In practice that shelters the first $2,000,000, so the tax falls on the value above the threshold rather than on the whole estate. |
| The old cliff is gone; rates reach 16% | Before 2023 an estate just over the line was taxed on its entire value. The 2023 law removed that cliff. Above the threshold the graduated rates run up to 16%. A return is generally due nine months after the death. |
| What is exempt | What it means |
|---|---|
| Unlimited marital deduction | Property that passes to a surviving spouse is fully deductible, so a transfer to a spouse is not taxed no matter its size. Tax may apply later when that spouse dies. |
| Charitable transfers | Gifts to qualifying charities are deducted from the taxable estate. Amounts left to charity are not counted when the estate is measured against the $2,000,000 threshold. |
| No portability between spouses | Massachusetts does not let a surviving spouse carry over a deceased spouse’s unused exemption. Each estate uses its own $2,000,000, so planning matters for married couples with combined assets over that figure. |
What you can do right now
Concrete, neutral steps if an estate in Massachusetts may be near the threshold. This is general information, not tax or legal advice.
- Add up the gross estate
Total the value of everything the person owned at death, including real estate, accounts, and life insurance they controlled. If the estate is over $2,000,000, a Massachusetts return is likely required.
- File Form M-706 on time
The Massachusetts estate tax return is Form M-706, filed with the Department of Revenue. It is generally due within nine months of the death. Confirm the current form and deadline before filing.
- Apply the marital and charitable deductions
Subtract transfers to a surviving spouse and to qualifying charities before measuring the estate against the threshold. These deductions can lower or remove the tax.
- Get help for estates near or over $2,000,000
The credit and the removed cliff changed how the tax is figured after 2023. Confirm the numbers with the Department of Revenue or an estate attorney before filing.
Estate tax turns on the total value of the estate and the current exemption. The state department of revenue publishes the return and the threshold in effect for the year of death.

What people in Massachusetts get wrong about estate tax
Massachusetts levies a state estate tax that the estate pays before assets pass to heirs. A 2023 tax relief law reshaped it. For deaths on or after January 1, 2023, the effective exemption is $2,000,000, up from the old $1,000,000. Estates worth $2,000,000 or less owe nothing. The law works through a credit of up to $99,600, which shelters the first $2,000,000 so that only the value above the threshold is taxed. Just as important, the 2023 change removed the old cliff. Under the prior rule an estate that crossed the line was taxed on its entire value, not just the excess. Above the threshold the graduated rates run up to 16%. Transfers to a surviving spouse are fully deductible, and so are gifts to charity. Massachusetts does not allow portability between spouses. Keep this separate from an inheritance tax, which the heir would pay based on relationship. Massachusetts has an estate tax but no inheritance tax, and the federal estate tax can still apply on top.
Common questions
Does Massachusetts have an estate tax?
Yes. Massachusetts levies a state estate tax under M.G.L. c. 65C. The estate pays it, and for deaths on or after January 1, 2023 it applies once the estate is worth more than $2,000,000.
What is the estate tax exemption in Massachusetts?
The effective exemption is $2,000,000 for deaths on or after January 1, 2023, raised from $1,000,000. A credit of up to $99,600 shelters the first $2,000,000, so only the value above it is taxed.
Does the whole estate get taxed if it goes over $2,000,000?
No, not anymore. The 2023 law removed the old cliff. Now only the value above $2,000,000 is taxed, at graduated rates up to 16%.
Are transfers to a spouse taxed in Massachusetts?
No. Massachusetts allows an unlimited marital deduction, so property that passes to a surviving spouse is not taxed, no matter its value. Tax may apply later when that spouse dies.
Is Massachusetts estate tax the same as inheritance tax?
No. The estate tax is paid by the estate before assets pass, and only when the estate is over $2,000,000. An inheritance tax is paid by the heir. Massachusetts has no inheritance tax.
