Massachusetts Estate Tax 2026: $2M Exemption and Rates

The Massachusetts estate tax starts above $2 million, and a 2023 reform raised that threshold and added a credit that softened the old cliff.1 Add up the whole estate, not just the cash, before assuming it is under that line. This guide tells you whether your estate owes and how the rules changed.

If you are planning your own estate or settling a parent's, the figures below are the ones that decide it.

Massachusetts Estate Tax at a Glance

Here is the full picture in one table. Massachusetts runs a graduated estate tax, a transfer tax on the value of the decedent's estate that the estate pays before anything is distributed to a beneficiary.1

How the Massachusetts Estate Tax Works

The estate tax is a tax on the value of everything a person owned at death, paid by the estate itself, not by the heirs. The executor files the return and pays the bill out of estate assets before the remainder is distributed.

For deaths on or after January 1, 2023, the threshold is $2,000,000, raised from $1,000,000.1 An estate owes no Massachusetts estate tax if the value of the federal taxable estate is not more than that figure, and a Massachusetts return is required when the gross estate plus adjusted taxable gifts exceeds it.1 Note that those are two different measures, so an estate can owe nothing and still have to file. Massachusetts delivers the relief in an unusual way: through a credit of up to $99,600 applied against the computed tax.1

Here is the part most summaries get wrong. Above the threshold, the tax is not computed on the excess alone. Massachusetts computes it on the whole of the amount subject to Massachusetts estate tax, using the Internal Revenue Code Section 2011 credit-for-state-death-taxes table (Table B, graduated, topping out at a marginal rate of 16 percent on the adjusted taxable estate above $10,040,000), and then reduces the result by the $99,600 credit.1 So an estate at $2.2 million is not taxed on $200,000. It is taxed on that whole amount and then handed the credit.

Both measures start from the federal estate, and the amount the tax is computed on starts from the federal gross estate, not from the cash in the bank.1 Ask the estate's attorney for the full list of what counts before deciding the estate is under $2 million.

Property outside Massachusetts is treated differently, and that difference runs in the family's favour. For deaths on or after August 1, 2025, the Department of Revenue arrives at the amount subject to Massachusetts estate tax by taking the federal gross estate, subtracting the value of real and tangible property located outside Massachusetts, adding the value of MA QTIP assets, and subtracting the allowable federal deductions.1 So a Massachusetts resident's out-of-state vacation home, and the tangible property in it, are not inside the amount the Massachusetts tax is computed on. That is a separate question from the $2,000,000 threshold, which is measured on the federal taxable estate, so ask the estate's attorney to run both rather than assuming they work the same way.

The tax is not confined to Massachusetts residents, either. Someone who died a resident of another state but owned Massachusetts real or tangible property has an estate that computes Massachusetts estate tax on that Massachusetts property, on the same Table B basis.1 A Cape house owned by an out-of-state couple sits inside the Massachusetts system even though they never lived here.

Married couples should not assume the federal spousal rule carries over. Under federal law, a surviving spouse can use a deceased spouse's unused federal exclusion only if the first spouse's executor files a federal estate tax return and elects it on that return.2 The Massachusetts $2,000,000 threshold is tested on each estate's own federal taxable estate.1 If your combined assets are above $2 million, ask an estate attorney, while both spouses are living, how the Massachusetts threshold applies to each of your estates.

The executor is the one who handles all of this. The estate files a Massachusetts estate tax return and pays any tax out of estate assets before the remaining property passes to heirs. Because the return, the credit, and the graduated schedule turn on the exact value of the estate, an executor settling an estate near the $2 million line should get a professional to run the numbers rather than estimate.1

What the 2023 Reform Changed

Before 2023, Massachusetts had a harsh feature known as a cliff. An estate that crossed the threshold was taxed on its entire value, with no offset at all. An estate a few thousand dollars over the old $1 million threshold was taxed on all of its value, not on the few thousand.1

The 2023 reform did two things. It raised the threshold from $1 million to $2 million, and it introduced the credit of up to $99,600, which is what softened that cliff.1 The tax is still computed on the whole amount subject to Massachusetts estate tax; what changed is that the credit now offsets part of the result, so an estate just over the line is no longer hit with the undiluted bill. The combination took estates whose federal taxable estate is $2,000,000 or less out of the tax entirely and eased the jolt for those that still owe. If you are reading older guidance that describes a $1 million threshold or a full-estate cliff, it is out of date for any death in 2023 or later.

The practical effect of the change is real money. Under the old rules, an estate of $1.1 million was over the $1 million line, so Massachusetts taxed its entire value. That same estate today, sitting under the $2 million exemption, owes nothing.1 For families in the band between the old and new thresholds, the reform was the difference between a tax on the whole estate and no tax at all.

This is general information, not legal or tax advice. For an estate near the $2 million line, a Massachusetts estate attorney can confirm exactly how the credit and the current schedule apply to your situation.1

Estate Tax Is Not Inheritance Tax

These two terms get used as if they mean the same thing. They do not, and the difference decides who is liable.

An estate tax is paid by the estate, out of the deceased person's assets, before anything is distributed. An inheritance tax applies to the taxable value of what is left to each heir, and the heirs are liable for it even though the estate pays it.3 What Massachusetts imposes is the first kind: the Department of Revenue describes it as a transfer tax on the value of the decedent's estate before distribution to any beneficiary.1 So the bill lands on the estate and is settled by the executor before you receive anything, rather than arriving as a separate charge calculated on your own share.

For heirs, that means the estate tax can reduce what is left to divide, but it is paid out of estate assets rather than billed to each beneficiary.

Not the Federal Tax, Not Medicaid Recovery

Two other things get confused with the state estate tax. Both are different, and the distinction matters.

The federal estate tax is separate, and its exclusion is far higher. For deaths in 2026 the federal basic exclusion amount is $15 million per decedent, seven and a half times Massachusetts' $2 million threshold.2,1 An estate that falls in the gap between the two figures can owe Massachusetts tax while owing nothing to the IRS, so being under the federal exclusion does not mean no death tax is owed.2 The federal tax is figured and filed on IRS Form 706, and Massachusetts has its own return; the Department of Revenue says changes to federal estate tax law after December 31, 2000 have no impact on the Massachusetts estate tax.2,1

Medicaid estate recovery is not a tax at all. Federal law requires every state to run an estate recovery program that seeks repayment from the estates of certain Medicaid enrollees, including those 55 or older, for nursing-facility and home and community-based services.4 It applies to a different group of people, for a different reason, under separate rules. If a parent received Medicaid-paid nursing home care, recovery is its own question to raise with the estate's attorney. We cover it fully in Medicaid estate recovery; the similar name does not make them one issue.

Add up everything the estate holds, not just the cash, and see whether the total could clear $2 million.1 If it is close, bring in a Massachusetts estate attorney, because the credit and the post-2023 schedule turn on details worth getting right.
