An irrevocable trust is included in the grantor’s gross estate when the grantor kept strings attached to the transferred property. Four Internal Revenue Code sections do the pulling: Section 2036 captures retained use, enjoyment, or income; Section 2038 captures a retained power to alter, amend, revoke, or terminate the trust; Section 2037 captures transfers that only vest if a beneficiary outlives the grantor; and Section 2042 captures life insurance proceeds over which the insured held incidents of ownership. The label on the trust document is irrelevant. What matters is what the grantor actually gave up.
For 2026, the federal estate tax exemption is $15 million per individual, so these inclusion questions produce an actual tax bill only for estates near or above that line.1Internal Revenue Service. What’s New – Estate and Gift Tax Married couples can effectively shield $30 million by combining both spouses’ exemptions through portability, and the generation-skipping transfer exemption is also $15 million for 2026.2Internal Revenue Service. Revenue Procedure 2025-32 Inclusion still matters below those thresholds for a different reason, discussed near the end: it determines whether assets get a stepped-up cost basis at death.
Keeping the Right to Use the Property or Collect Its Income
Section 2036 is where most irrevocable trusts fail. If you transferred property to the trust but kept the right to possess it, enjoy it, or receive income from it for life (or for a period that does not end before your death), the full value of that property comes back into your gross estate.3Office of the Law Revision Counsel. 26 USC 2036 – Transfers With Retained Life Estate The statute reaches both express retentions written into the trust and informal, implied understandings. What you actually did with the property matters as much as what the document says.
Living in a House You Transferred
Deeding your home into an irrevocable trust and continuing to live there rent-free is the textbook trigger. If you stay without paying fair market rent, the IRS treats the arrangement as retained possession, and the full value of the home is pulled back into the estate. Silence in the trust document doesn’t help; the pattern of occupancy without rent creates the implied agreement on its own.
Avoiding this requires a real lease at fair market rent, with payments actually flowing from you to the trust. The arrangement has to survive scrutiny of its economic reality, not just its paperwork.
Income Rights and Support Obligations
Section 2036 also catches a retained right to income. If the trust entitles you to all net income, dividends, or interest from trust property for life, those assets are included in full.
A related trap: when trust income gets used to satisfy your personal legal obligations, especially the duty to support minor children, the Treasury regulations treat that income as yours.4eCFR. 26 CFR 1.662(a)-4 – Amounts Used in Discharge of a Legal Obligation Consistent distributions covering what you would otherwise owe look like a retained economic benefit of the underlying assets.
Deciding Who Gets What
The second prong of Section 2036 reaches a subtler problem. If you kept the right to designate who possesses or enjoys the property or its income, alone or with someone else, the assets are included.3Office of the Law Revision Counsel. 26 USC 2036 – Transfers With Retained Life Estate The classic example is a grantor who serves as sole trustee with open-ended discretion over distributions. The assets are technically out of your name, but you still choose the beneficiaries and the timing. That’s enough.
Keeping a Power to Change the Trust
Section 2038 asks a different question: not what you kept the right to enjoy, but what you kept the right to change. If at the time of your death you held a power to alter, amend, revoke, or terminate any interest in the trust, those assets come into the gross estate.5Office of the Law Revision Counsel. 26 USC 2038 – Revocable Transfers The power doesn’t need to benefit you. The ability to reshuffle beneficiaries or adjust their shares is enough. And the capacity in which you hold it (trustee, protector, or individual) doesn’t change the result.
Section 2038 also has a three-year lookback. Giving up one of these powers within three years of your death puts the assets back in the estate as if you never let go.
The HEMS Safe Harbor
A grantor who serves as trustee can escape inclusion under Sections 2036 and 2038 when distribution powers are limited by an “ascertainable standard.” In practice this means distributions are restricted to a beneficiary’s health, education, maintenance, and support, commonly abbreviated as HEMS. A power limited by this standard isn’t a general power of appointment and doesn’t give the grantor the kind of unconstrained discretion that triggers inclusion.6Office of the Law Revision Counsel. 26 USC 2041 – Powers of Appointment, General Rule
The reason HEMS works is that it creates an objective limit a court can enforce. A trust that lets the trustee distribute “as the trustee sees fit” offers no such limit, and a grantor-trustee holding that discretion has an inclusion problem.
Power to Swap Assets
Many irrevocable grantor trusts give the grantor a power to substitute assets of equivalent value in and out of the trust. This power, authorized under Section 675(4)(C), is what makes the trust a grantor trust for income tax purposes, meaning the grantor pays the income tax on trust earnings and effectively shrinks the taxable estate without that payment counting as an additional gift.7Office of the Law Revision Counsel. 26 USC 675 – Administrative Powers
The IRS has generally accepted that a properly structured substitution power does not trigger inclusion under Section 2036 or 2038, provided the swap truly involves property of equivalent value. The trust should require an independent trustee to verify equivalence, or at a minimum require equivalent value on its face. Without that guardrail, the power starts to look like unrestricted control over the trust’s assets.
Transfers That Only Vest at Death
Section 2037 covers a narrower situation. Property is included when both of two conditions are met:8Office of the Law Revision Counsel. 26 USC 2037 – Transfers Taking Effect at Death
- The beneficiary can obtain possession or enjoyment of the property only by surviving the grantor. If any beneficiary had an independent path to the property during the grantor’s lifetime, this condition fails.
- The grantor retained a reversionary interest (a possibility the property returns to the grantor or the grantor’s estate, or that the grantor regains a power of disposition over it) worth more than 5% of the property’s value immediately before death.
The 5% figure is an actuarial valuation that uses the Section 7520 rate in effect at the time, which changes monthly.9Internal Revenue Service. Section 7520 Interest Rates Section 2037 triggers far less often than 2036 or 2038, but it catches trusts drafted so that remainder interests vest only on the grantor’s death and no beneficiary has any lifetime access.
Life Insurance Trusts and Incidents of Ownership
Irrevocable life insurance trusts exist to keep policy death benefits out of the insured’s estate. Section 2042 pulls the full death benefit back in if the insured held any “incidents of ownership” in the policy at death.10Office of the Law Revision Counsel. 26 USC 2042 – Proceeds of Life Insurance
The Treasury regulations define incidents of ownership broadly: the power to change the beneficiary, surrender or cancel the policy, assign it, pledge it as collateral, or borrow against its cash value.11GovInfo. 26 CFR 20.2042-1 – Proceeds of Life Insurance Any one of them is enough. Powers held indirectly, such as through a corporation the insured controls, count too. This is why the insured grantor should not serve as trustee if the trustee role carries any of these powers.
The Three-Year Rule for Existing Policies
If you transfer an existing policy to an irrevocable trust and die within three years, Section 2035 includes the full death benefit as though you still owned it.12Office of the Law Revision Counsel. 26 USC 2035 – Adjustments for Certain Gifts Made Within 3 Years of Decedent’s Death When the trust itself applies for and purchases a brand-new policy from the beginning, the three-year rule generally does not apply, because the insured never personally held incidents of ownership in that policy. The grantor contributes cash to the trust, and the trustee buys the policy and pays the premiums.
The Bona Fide Sale Exception
Sections 2036, 2037, and 2038 each carve out transfers made as “a bona fide sale for an adequate and full consideration in money or money’s worth.”3Office of the Law Revision Counsel. 26 USC 2036 – Transfers With Retained Life Estate If you sold assets to the trust at fair market value rather than gifting them, these inclusion rules don’t reach the transfer even where some interest or control was retained.
This exception underlies the sale-to-grantor-trust technique. The grantor sells appreciated assets to a grantor trust in exchange for a promissory note. The sale produces no capital gains tax because the IRS treats grantor and trust as the same taxpayer for income tax purposes, and Sections 2036 and 2038 don’t apply because the trust paid full consideration. Future appreciation grows outside the estate; only the note itself (and whatever remains unpaid at death) sits inside it.
Why Inclusion Can Be Worth It Anyway
Keeping assets out of the gross estate carries a cost that surprises many families. Under Section 1014, property included in a decedent’s gross estate generally receives a basis equal to its fair market value at the date of death, wiping out unrealized capital gains.13Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Assets excluded from the gross estate don’t get that step-up. Revenue Ruling 2023-2 confirmed that property owned by an irrevocable grantor trust and excluded from the estate keeps the grantor’s original cost basis after death.14Internal Revenue Service. Internal Revenue Bulletin 2023-16, Revenue Ruling 2023-2 Stock the grantor bought for $100,000 that grew to $2 million keeps its $100,000 basis in the beneficiaries’ hands, exposing $1.9 million to capital gains tax on sale.
For estates above $15 million, removing assets from the gross estate usually saves far more in estate tax than beneficiaries lose in capital gains. For estates comfortably below the exemption, a successful exclusion can cost the family more in capital gains tax than it ever would have saved in estate tax. The arithmetic deserves a close look from a tax advisor before the trust is funded, not after.
Disclosure on Form 706
Even when the trust properly keeps assets out of the gross estate, the executor must still disclose it. Form 706 requires reporting of lifetime transfers on Schedule G, which covers transfers potentially falling within Sections 2035, 2036, 2037, or 2038.15Internal Revenue Service. About Form 706, United States Estate and Generation-Skipping Transfer Tax Return The executor lists the property, the date of transfer, and the nature of the transaction, and the IRS may request the trust instrument. Full disclosure is required whether or not the executor concludes the assets are taxable. Reporting a trust that turns out to be excluded is a small matter; omitting one the IRS later decides should have been included is not.
