Estate tax planning helps Massachusetts individuals and families structure wealth transfers while accounting for state and federal estate and gift tax rules. In 2026, Massachusetts generally requires an estate tax return when the gross estate plus applicable adjusted taxable gifts exceeds $2 million, while the federal basic exclusion amount is $15 million per individual. Executives, founders, and other high-net-worth individuals may require additional planning when stock options, RSUs, concentrated stock positions, business interests, or other appreciating assets significantly affect estate value and liquidity.
Key Takeaways
- Massachusetts and federal estate taxes operate under different rules and thresholds. An estate may face Massachusetts estate tax even when no federal estate tax is due.
- For deaths in 2026, the federal basic exclusion amount is $15 million per individual, while the Massachusetts estate tax filing threshold remains $2 million.
- Stock options, RSUs, concentrated company stock, business interests, and other appreciating assets can cause an estate’s value to change substantially over time.
- Estate planning for illiquid or concentrated wealth should consider how an estate would obtain cash to meet taxes and other obligations without forcing an unfavorable asset sale.
- Gifting and trust strategies may allow future appreciation to occur outside an individual’s taxable estate in appropriate circumstances, but income, gift, estate, and other tax consequences should be evaluated together.
- Estate planning for executives and founders should be coordinated with tax, financial, and other professional advisors rather than approached as a stand-alone legal exercise.

What Are the Massachusetts Estate Tax Rules in 2026?
Massachusetts imposes its own estate tax, separate from the federal system.
For decedents dying in 2023 and thereafter, a Massachusetts estate tax return generally must be filed when the gross estate plus applicable adjusted taxable gifts exceeds $2 million. Estates of decedents dying on or after January 1, 2023, also receive a credit of up to $99,600 against the Massachusetts estate tax.
Importantly, Massachusetts has decoupled its estate tax from subsequent changes in federal estate tax law. Massachusetts generally calculates its estate tax using provisions of the Internal Revenue Code as they existed on December 31, 2000.
That distinction means an estate can be well below the federal exclusion while still facing Massachusetts estate tax exposure.
How Does the Federal Estate Tax Differ From Massachusetts Estate Tax?
The federal threshold is substantially higher.
For individuals dying in 2026, the federal basic exclusion amount is $15 million. The federal gift and estate tax systems are also unified, meaning taxable lifetime gifts generally use part of the same exclusion that would otherwise be available at death.
The federal system also provides planning opportunities that differ from Massachusetts law, including portability of a deceased spouse’s unused federal exclusion when the required election is properly made.
Because the two systems operate differently, a Massachusetts resident may need a plan that addresses state estate tax exposure years before federal estate tax becomes a concern.
How Can Stock Options, RSUs, and Company Stock Affect Estate Planning?
Executives and founders often accumulate wealth differently from individuals whose assets consist primarily of cash, diversified investments, and a residence.
An estate may contain:
- Vested or unvested stock options
- Restricted stock units (RSUs)
- Concentrated publicly traded company stock
- Closely held business interests
- Carried or other equity interests
- Employer retirement benefits
These assets can create valuation and timing issues.
A concentrated stock position, for example, may appreciate significantly between the time an estate plan is created and the owner’s death. Closely held business interests can be even more difficult to value because there may be no readily available market price.
Executive compensation may also be subject to plan-specific rules governing what happens after disability, retirement, or death. Estate planning documents should therefore be coordinated with the terms of the underlying compensation arrangements.
Why Does Liquidity Matter in Estate Tax Planning?
A high-value estate is not necessarily a liquid estate.
A founder might have substantial net worth concentrated in a privately held company. An executive may hold significant company stock but relatively little cash. A family may own valuable real estate that generates income but cannot be sold quickly.
Estate taxes, administration expenses, debts, and other obligations can create cash needs after death.
Planning may therefore consider how those expenses would be paid without requiring beneficiaries or fiduciaries to sell valuable assets at an undesirable time. Appropriate strategies depend heavily on the estate’s composition and the owner’s broader objectives.
How Can Gifting Affect Future Estate Tax Exposure?
Lifetime gifting can be one component of estate tax planning.
For 2026, the federal annual gift tax exclusion remains $19,000 per recipient. Gifts exceeding that amount do not necessarily trigger an immediate gift tax, but they may require reporting and may use part of the donor’s lifetime federal exclusion.
For individuals holding appreciating assets, the timing of a transfer may matter because future appreciation generally occurs in the hands of the recipient or trust rather than remaining in the donor’s estate.
That does not mean gifting is always advantageous. Transfers can create income tax, basis, control, cash flow, and family considerations that should be evaluated before assets are transferred.
Estate tax reduction should not be considered in isolation from the broader financial consequences of a gift.
How Can Trusts Be Used in Estate Tax Planning?
Trusts can serve different purposes depending on the client’s assets and objectives. Some provide management and probate benefits without removing assets from the taxable estate. Others may be structured to transfer assets or future appreciation outside the estate when applicable legal requirements are satisfied.
For executives and founders, trust planning may be considered in connection with:
- Appreciating company interests
- Family wealth transfers
- Life insurance
- Business succession
- Long-term asset management
- Charitable objectives
The appropriate structure depends on the degree of control an individual wants to retain, the nature of the assets, family circumstances, and applicable tax rules.

FAQs About Estate Tax Planning in Massachusetts
Should Estate Planning Be Coordinated With Your Other Advisors?
Yes. Seder Law regularly works alongside clients’ accountants, financial advisors, valuation professionals, and other advisors so that legal planning fits within the broader financial and tax strategy.
Are RSUs and stock options included in an estate?
Equity compensation can affect the value transferred at death, but treatment depends on the type of award, whether it has vested or been exercised, and the governing plan documents. Executives should review compensation arrangements as part of their estate planning rather than assuming all equity awards receive identical treatment.
Can I give company stock to my children to reduce my estate?
Lifetime transfers of stock may be possible and can shift future appreciation, but they can also have gift tax, income tax basis, control, and financial consequences. The appropriate approach depends on the individual’s holdings and objectives.
How often should a high-net-worth estate plan be reviewed?
A review may be appropriate whenever there is substantial appreciation, a business transaction, new equity compensation, a change in family circumstances, or a significant change in tax law. Even without a major event, periodic review helps ensure the plan still reflects current asset values and objectives.
