Massachusetts has its own estate Tax rules, which can affect individuals with estates over a certain exemption amount; understanding how to avoid estate tax in Massachusetts is key for estate planning, eligibility, calculation methods, and timing. This comprehensive guide covers who the Massachusetts estate tax impacts, how it is calculated, strategies to minimize or avoid it, current exemption thresholds, important deadlines, and critical compliance issues for residents and nonresidents with property in the state.
Direct Answer
The Massachusetts estate tax applies to estates exceeding the $2 million exemption as of recent updates (verify every year on official Massachusetts sources).
To avoid or minimize this tax, strategies include reducing your taxable estate below the exemption through lifetime gifts, charitable donations, or establishing certain trusts.
Massachusetts does not tax the first $2 million, but once the estate exceeds this, only the amount over is subject to tax.
There are no portability provisions—unused exemption cannot be transferred to a surviving spouse.
Gifting assets during your lifetime may remove them from your taxable estate, but federal gift tax rules and reporting may apply.
Out-of-state property is generally excluded from the Massachusetts estate tax calculation for nonresidents, while Massachusetts real and tangible property is always subject.
Consult official Massachusetts estate tax forms and instructions for annual changes and filing steps, and always confirm with official Massachusetts sources.
Scope & Who This Applies To
The Massachusetts estate tax targets estates of decedents who were Massachusetts residents, as well as nonresidents who own real or tangible property in the state.
Applies to individuals with a total taxable estate value exceeding $2 million (per 2025 sample, subject to legislative change).
No distinction is made based on marital status for the purpose of the state exemption—exemption is not portable between spouses.
Estates with property in other states may have complex allocation and apportionment issues.
Businesses, trusts, and other entities are affected if the decedent held qualifying interests in Massachusetts property.
Federal estate tax may also apply at much higher thresholds; Massachusetts estate tax is separate and in addition to any federal taxes.

How the Tax Is Calculated
The taxable estate includes all assets owned at death (real estate, bank accounts, securities, retirement accounts, certain life insurance, business interests, etc.).
Subtract debts, funeral and administrative expenses, qualified charitable deductions, and other allowable deductions as per official Massachusetts rules.
If the net estate exceeds $2 million (sample/illustrative for 2025), only the amount in excess is subject to Massachusetts estate tax.
The state uses a progressive rate schedule (approx. 0.8% to 16%, sample), applied only to the portion of the estate that exceeds $2 million.
For nonresidents, only Massachusetts-sited real and tangible property is included.
Massachusetts does not allow “portability”: if one spouse dies without using the full exemption, the remainder does not transfer to the surviving spouse.
No estate tax owed at or below threshold (2025, check updates annually)
$2,000,001 to $3,000,000
~0.8% to 7%
All
Progressive schedule; sample/illustrative
$3,000,001 to $10,000,000+
~7% to 16%
All
Top rate applies to amounts well above threshold (sample/illustrative)
Representative example: An estate of $2.5 million (sample/illustrative, 2025 rules) would face Massachusetts estate tax only on the $500,000 above the exemption.
On $500,000 subject to tax, using a progressive schedule, a rough (non-official) liability might be $20,000 to $40,000 (sample)—actual tax varies depending on deduction eligibility and exact rate schedule.
The gross estate can usually deduct debts, mortgages, certain funeral and administration expenses, and charitable bequests.
Marital deduction: assets left to a surviving spouse (if U.S. citizen) are generally deductible from the MA estate calculation, but the unused exemption is not transferrable (no portability).
Charitable deduction: gifts/bequests to qualifying charities are typically deductible.
Credits: Massachusetts allows a state death tax credit in line with its own calculations; not all federal credits apply.
Gather all documentation on decedent’s assets, debts, prior gifts, and any prior tax returns (federal and state).
Calculate gross estate and allowable deductions; determine if total exceeds the $2 million (sample/illustrative) exemption.
If tax is due, complete Massachusetts Form M-706 and file within nine months of death.
In complex cases, attach supporting schedules and federal Form 706 as required.
Payment must be made by the same deadline; file for a six-month extension if needed (extension is for filing, not payment).
Submit directly to the Massachusetts Department of Revenue; use certified mail or e-filing if supported for tracking.
Preserve copies of all filings and documentation for at least three years after filing.
Common Pitfalls & Compliance Notes
Missing the nine-month filing or payment deadline leads to penalties and interest.
Failing to value property properly (especially business interests or out-of-state real estate) can trigger audits.
Relying on outdated exemption amounts—Massachusetts rules have changed several times in recent years.
Assuming the federal estate tax exemption (much higher) applies to the state tax—it often does not.
Improper allocation of deductions between state and federal returns; state rules can differ.
Not keeping records of gifts made within three years of death, which may be pulled back into the estate for calculation.
