The Massachusetts threshold is just $2 million and is not indexed to inflation, but the tax is highly plannable. The main strategies are credit shelter trusts for married couples, irrevocable life insurance trusts, lifetime gifting, qualified personal residence trusts for the home, and charitable giving, usually combined to fit the size and shape of the estate.
If you have read our overview of how the Massachusetts estate tax works, you know the hard part: the threshold is just $2 million, it is not indexed to inflation, and an ordinary North Shore family with a home, retirement accounts, and life insurance can easily cross it. The good news is that this is one of the most plannable taxes there is. This article walks through the main strategies families use to reduce or eliminate it.
1. Credit Shelter (Bypass) Trusts for Married Couples
This is the cornerstone of married-couple planning, and the single biggest opportunity most couples miss. Massachusetts has no portability between spouses, meaning the first spouse's $2 million threshold can be wasted if everything simply passes to the survivor.
A credit shelter trust captures the first spouse's threshold at their death, sheltering roughly $2 million in a trust that benefits the survivor during life but is not counted in the survivor's taxable estate. Done correctly, this lets a couple protect approximately $4 million instead of $2 million. The survivor can still benefit from the trust assets; they simply are not taxed again at the second death.
2. Irrevocable Life Insurance Trusts (ILITs)
Here is a fact that surprises people: the life insurance policy you own is counted in your taxable estate. A $1 million policy meant to protect your family can be the very thing that pushes you over the $2 million line, and then gets taxed.
An irrevocable life insurance trust owns the policy instead of you. Structured and administered properly, the death benefit passes to your family outside your taxable estate. For families whose life insurance is what tips them over the threshold, this is often the highest-impact single move available.
3. Lifetime Gifting
Massachusetts does not impose a separate gift tax, which creates genuine opportunity to move assets out of your estate while you are alive. Thoughtful annual gifting to children and grandchildren, over years, can meaningfully reduce the size of the taxable estate.
A nuance worth flagging: While Massachusetts has no standalone gift tax, lifetime gifts can still interact with the estate tax calculation in technical ways, and large gifts have other consequences (including for capital-gains basis and, if long-term care is a concern, the MassHealth lookback). Gifting is powerful but should never be done in a vacuum. This is squarely a "do it with your attorney" strategy.
4. The Home: Qualified Personal Residence Trusts
For families whose home is a large share of their estate, a qualified personal residence trust (QPRT) can transfer the home to the next generation at a reduced gift value while you keep the right to live there for a set term. It is more specialized, but for the right family with a valuable home, it can remove a significant asset from the taxable estate.
5. Charitable Giving
Gifts to charity, whether outright bequests or through charitable trusts, reduce the taxable estate dollar for dollar while supporting causes you care about. For families who are charitably inclined anyway, structuring that giving through the estate plan turns a personal value into a tax advantage. See our article on charitable giving in your estate plan.
How Do These Estate Tax Strategies Work Together?
These tools are rarely used in isolation. A typical plan for a family over the threshold might combine a credit shelter structure, an ILIT for the life insurance, and a measured gifting program, each doing part of the work. The right mix depends entirely on the size and shape of your estate. What is consistent is the lesson: families who plan reduce or eliminate a tax that families who do nothing simply pay.
