Estate Tax in Massachusetts: Complete Guide 2026

Tax information is for educational purposes only and does not constitute tax advice. Consult a licensed estate planning attorney for your specific situation.

Massachusetts has one of the lowest estate tax exemptions in the nation at approximately ~$2.00 million. Unlike the federal estate tax, which exempts estates worth approximately ~$7 million or more, Massachusetts taxes estates exceeding just ~$2.00 million — and like New York, the tax applies to the entire estate once the threshold is exceeded, not just the excess. This means Massachusetts residents with moderate wealth, including those whose primary asset is a home in a high-cost area, must plan carefully to manage their estate tax exposure.

Massachusetts Estate Tax Rates and Exemption (2026)

Parameter	Projected 2026 Level
Estate tax exemption (filing threshold)	~$2.00 million
Lowest effective rate	~0.80%
Highest marginal rate	~16.00%

Massachusetts Estate Tax Rate Schedule

Massachusetts uses a graduated rate structure that applies to the entire taxable estate, with a credit that effectively eliminates tax for estates below ~$2.00 million:

Taxable Estate	Approximate Marginal Rate
$0 — $1,000,000	~0.80% to ~5.60%
$1,000,001 — $2,000,000	~6.40% to ~8.00%
$2,000,001 — $4,000,000	~8.80% to ~10.40%
$4,000,001 — $6,000,000	~11.20% to ~12.80%
$6,000,001 — $8,000,000	~13.60% to ~14.40%
$8,000,001 — $10,040,000	~15.20%
Over $10,040,000	~16.00%

The Effective Cliff

While Massachusetts technically uses a graduated rate schedule starting from the first dollar, a unified credit eliminates tax for estates under ~$2.00 million. Once the estate exceeds ~$2.00 million, the credit does not fully offset the graduated tax, creating an effective cliff:

Estate Value	Estimated Massachusetts Estate Tax
$2,000,000	$0
$2,100,000	~$99,600
$2,500,000	~$133,200
$3,000,000	~$182,000
$5,000,000	~$391,600
$10,000,000	~$1,018,800

The jump from $0 to approximately ~$99,600 when an estate exceeds $2.00 million by just $100,000 illustrates the punishing cliff effect.

Why Massachusetts’s Low Exemption Matters

Massachusetts’s ~$2.00 million exemption is significantly lower than the federal exemption and catches many estates that would not owe federal tax:

Exemption Level	Estate Tax
Federal (if TCJA sunsets)	~$7.00 million per person
Massachusetts	~$2.00 million per person
Gap	~$5.00 million

In high-cost Massachusetts cities like Boston, Cambridge, Newton, and Brookline, a primary residence alone can be worth ~$1.5 million to ~$3.0 million. Add retirement accounts, life insurance, and savings, and many middle-class families find themselves above the ~$2.00 million threshold. Massachusetts has been under legislative pressure to raise its exemption, but as of 2026, the ~$2.00 million threshold remains.

What Is Included in the Massachusetts Taxable Estate

Massachusetts generally conforms to the federal definition of the gross estate:

Real property (including out-of-state property owned by Massachusetts domiciliaries)
Financial accounts, investments, and retirement accounts
Life insurance proceeds (if the deceased owned the policy)
Business interests
Revocable trusts and jointly held property

Massachusetts offers an unlimited marital deduction for assets passing to a surviving spouse, as well as a charitable deduction for qualifying charitable bequests.

Comparison to Other Northeast States

State	Exemption	Top Rate	Cliff?
Massachusetts	~$2.00 million	~16.00%	Yes (effective)
Connecticut	~$13.61 million	~12.00%	No
New York	~$6.94 million	~16.00%	Yes (105%)
Maine	~$6.80 million	~12.00%	No
Vermont	~$5.00 million	~16.00%	No
Rhode Island	~$1.77 million	~16.00%	No
New Hampshire	None	N/A	N/A

Massachusetts and Rhode Island have the lowest estate tax exemptions in the Northeast. New Hampshire has no estate tax, making it an attractive destination for wealthy Massachusetts residents considering relocation.

Tips for Minimizing Massachusetts Estate Tax

Use irrevocable life insurance trusts (ILITs). Life insurance proceeds are included in the taxable estate if the deceased owned the policy. Transferring ownership to an ILIT removes these proceeds from the estate.
Make lifetime gifts. Massachusetts does not impose a state gift tax. Gifts reduce the size of the estate for Massachusetts estate tax purposes, even if they use some of the federal gift tax exemption. Strategic gifting can bring an estate below the ~$2.00 million threshold.
Maximize the marital deduction. Assets passing to a surviving spouse are exempt. A credit shelter trust (bypass trust) can help preserve both spouses’ exemptions.
Consider a qualified personal residence trust (QPRT). For families whose primary home pushes the estate over the exemption, a QPRT transfers the home to beneficiaries at a discounted value for estate tax purposes.
Charitable giving. Charitable bequests are fully deductible. A charitable remainder trust can provide income to heirs while reducing the taxable estate.
Evaluate a domicile change. New Hampshire has no estate tax and is adjacent to Massachusetts. Some residents with large estates relocate, though this must be a genuine change of domicile with supporting evidence.
