A couple in their early seventies in suburban Boston sits down with their accountant expecting a routine year-end check-in. They own a $2.1 million home, have $1.4 million in retirement accounts, $400,000 in a brokerage account, $300,000 in cash, and a life insurance policy they own personally. They have always assumed the federal estate tax exemption, now $15 million per individual in 2026, makes their estate a non-issue. Then they hear two words that stop the conversation cold: Massachusetts estate tax.
The shock is common. Variations of this scenario fill threads in r/EstatePlanning and r/Bogleheads, where Massachusetts residents repeatedly post some version of “I thought I was way under the limit, why am I getting hit with a six-figure state tax bill?”
The answer is straightforward: Massachusetts runs its own estate tax, on its own scale, and it does not track the federal number.
The Numbers That Actually Matter
- Couple: 71-year-old married filing jointly, Massachusetts residents
- Gross estate: $4.2 million (home, retirement, brokerage, cash, personally owned life insurance)
- Federal exposure: Effectively zero
- Massachusetts exposure (worst case, no planning): Roughly $380,000
Why the Massachusetts Tax Is the Whole Story
Massachusetts taxes estates above a $2 million exemption, raised from $1 million in 2023, with a progressive rate that starts at 7.2% and tops out at 16%. The Commonwealth delivers that exemption through a credit of up to $99,600, which effectively shelters the first $2 million from tax. On a $4.2 million estate, the tax on the amount above $2 million produces roughly $200,000 to $220,000 in liability.
The bigger trap is structural.
Massachusetts does not allow portability of the unused exemption between spouses. If everything passes to the surviving spouse under the unlimited marital deduction, no tax is due at the first death, but the first spouse’s $2 million exemption disappears permanently. When the second spouse dies owning the full $4.2 million, only one $2 million exemption remains. Add a personally owned life insurance policy that gets pulled into the taxable estate at its full death benefit, and the combined bill can reach the $380,000 headline figure.
One comparison frames the stakes plainly. The 10-year Treasury note currently yields around 4.55%. A $380,000 tax bill represents roughly what a $2 million bond ladder generates in income over four full years. That is the cost of doing nothing.
Three Paths That Actually Move the Number
- Build a credit-shelter (bypass) trust. At the first death, up to $2 million in assets are placed in an irrevocable trust that benefits the surviving spouse while remaining excluded from their taxable estate. Both spouses’ $2 million exemptions get used, and analysis of this scenario suggests the single move cuts exposure by roughly $170,000. For most Massachusetts couples with estates between $2 million and $5 million, this is the highest-leverage step available.
- Move the life insurance into an Irrevocable Life Insurance Trust (ILIT). A policy owned personally by the insured is includible in the gross estate at the full death benefit. Re-titling the policy into an ILIT, properly structured and seasoned with at least three years before death, removes that death benefit from Massachusetts’s reach entirely under IRC Section 2042.
- Use lifetime gifts. Massachusetts abolished its state gift tax in 1971, meaning gifts made during life permanently remove assets from the Massachusetts taxable estate with no minimum waiting period and no state-level clawback. The federal annual gift exclusion is $19,000 per recipient in 2026, allowing a couple to transfer meaningful sums each year without triggering federal gift tax reporting. Systematic gifting is one of the more flexible tools available because it does not require trust formation or professional restructuring to begin.
- Change residency. Florida, Texas, and Nevada have no state estate tax. The trade-off is real. Massachusetts per capita personal income ran approximately $93,900 in 2024 per Bureau of Economic Analysis data, compared to roughly $76,400 in Florida in 2025. Beyond the income gap, family, doctors, and grandchildren rarely relocate with you. For a retired couple already weighing a move south, the estate-tax savings can serve as a meaningful tiebreaker, but the decision should account for the full picture of lifestyle and financial costs.
What To Do This Quarter
Pull the most recent statements together and total the gross estate, including the life insurance death benefit rather than the cash value. If the number exceeds $2 million, an existing “I love you” will that passes everything outright to the surviving spouse is almost certainly leaving money on the table. That arrangement feels generous and costs the family a six-figure tax bill that disciplined planning largely eliminates. The most important context is timing: the Massachusetts estate tax return is due nine months after death, and most of the strategies that reduce it require planning years before that deadline arrives.
It is also worth noting that the federal landscape shifted significantly in mid-2025. The One Big Beautiful Bill Act, signed into law on July 4, 2025, made the $15 million per-person federal estate tax exemption permanent and inflation-indexed going forward. That change eliminates federal estate tax exposure for the vast majority of Massachusetts families but does nothing to address the state-level bill. The gap between $15 million and $2 million is precisely where the planning opportunity sits.
Editor’s note: This update corrects the Massachusetts estate tax starting rate to 7.2% (from “around 7%”), updates the 10-year Treasury yield to approximately 4.55% reflecting mid-July 2026 levels, adds context on the $99,600 exemption credit, refreshes per capita income figures to the most recent Bureau of Economic Analysis data, adds Massachusetts lifetime gifting as a fourth planning path (noting the state has no gift tax), and incorporates the July 2025 One Big Beautiful Bill Act, which permanently set the federal estate tax exemption at $15 million per individual.
