Irrevocable Life Insurance Trust (ILIT): Removing the Death Benefit from Your Taxable Estate (2026)
An ILIT owns the policy. The grantor pays premiums via Crummey-letter gifts. At death, the death benefit lands outside the gross estate and provides liquidity for the family without triggering federal estate tax.
The Core Problem an ILIT Solves
Federal estate tax applies at 40% to the value of a decedent's gross estate above the unified exemption ($15,000,000 per person for 2026 under the OBBBA, $30,000,000 for married couples through portability). Under IRC §2042, life insurance proceeds are included in the gross estate if the decedent owned the policy or held any incidents of ownership in the policy at death.
For a high-net-worth family with an estate well above the exemption, the death benefit on a sizable life insurance policy can push the estate over the exemption and trigger 40% estate tax on amounts that would otherwise have gone to family. A $5,000,000 policy on a person with a $20,000,000 estate (already above the $15M exemption) effectively converts to $3,000,000 of after-tax benefit and $2,000,000 of federal estate tax due. Worse, the estate tax is typically due nine months after death, often forcing the family to liquidate assets to pay the tax bill.
The ILIT solves this by removing the policy (and the death benefit) from the gross estate entirely. The trust owns the policy, the trust holds all incidents of ownership, the grantor has no §2042 connection to the policy, and the death benefit passes to trust beneficiaries (children, grandchildren) outside the gross estate. The full death benefit reaches the beneficiaries; no estate tax applies to the proceeds.
What “Incidents of Ownership” Means
Treas. Reg. §20.2042-1(c)(2) defines incidents of ownership broadly as any right of the insured (or the insured's estate) to the economic benefits of the policy, including the right to:
- Change the beneficiary
- Surrender or cancel the policy
- Assign the policy or revoke an assignment
- Pledge the policy for a loan
- Borrow against the policy cash value
- Receive disability income or other living benefits
- Vote on any policy features
The ILIT structure works only if none of these rights are held by the insured. The trust must own all incidents of ownership. The insured cannot serve as trustee (most importantly), cannot retain any reversionary interest in the policy, and cannot be a beneficiary of the trust. Drafting errors that inadvertently leave the insured with any of these rights cause the §2042 inclusion to apply and pull the death benefit back into the gross estate.
How an ILIT Funds the Policy: Crummey Letters and the Annual Exclusion
Life insurance premiums must be paid. The trust holds the policy, but the trust needs cash to pay premiums. The grantor solves this by gifting cash to the trust each year in an amount sufficient to cover the premium. These gifts are subject to federal gift tax under IRC §2501.
The federal gift tax annual exclusion under IRC §2503(b) allows each person to gift up to $19,000 per recipient per year (for 2026; indexed annually) without using any lifetime exemption and without filing a gift tax return. But the annual exclusion applies only to gifts of present interests. A gift to an irrevocable trust is generally a gift of a future interest (the beneficiaries cannot use the money until the trust distributes it) and does not qualify for the annual exclusion.
The Crummey doctrine, from Crummey v. Commissioner, 397 F.2d 82 (9th Cir. 1968), solves this by giving each ILIT beneficiary a temporary right to withdraw their share of any contribution within a defined window (typically 30 days). The withdrawal right converts the gift to a present interest, qualifying it for the annual exclusion. After the window closes, the trustee uses the contributed funds to pay the insurance premium.
For an ILIT with five beneficiaries, the grantor can contribute up to $95,000 per year (5 × $19,000) without using any lifetime gift exemption. For a married couple gift-splitting under IRC §2513, the limit doubles to $190,000 per year. This is sufficient to fund substantial life insurance premiums in most planning scenarios.
Crummey letters must be issued each year for each contribution, and beneficiaries must actually have the legal right to withdraw. The IRS has scrutinized Crummey trust structures aggressively. Best practice is to document each contribution, issue written Crummey letters with delivery confirmation, and ensure beneficiaries have a reasonable opportunity to exercise withdrawal rights even though they almost never do.
The 3-Year Look-Back Under §2035
IRC §2035(a) creates a 3-year claw-back rule for transfers of life insurance policies. If the insured transfers an existing policy to an ILIT (or to anyone else) and dies within three years of the transfer, the policy proceeds are pulled back into the insured's gross estate as if the transfer had not occurred. The §2035 rule prevents deathbed transfers of life insurance to escape estate tax.
The §2035 rule applies only to transfers of existing policies. If the ILIT applies for the policy directly (the trustee is the applicant, the trust is named as owner from inception), there has been no transfer by the insured, and §2035 does not apply. The death benefit is excluded from the gross estate regardless of how soon after policy issue the insured dies.
For this reason, the standard ILIT practice is to (1) establish the trust before applying for the policy, (2) have the trustee apply for the policy with the trust as initial owner and initial beneficiary, and (3) fund the trust by Crummey gifts to pay the premiums going forward. Transferring an existing personally-owned policy to an ILIT works but introduces the 3-year risk window, which the family must outlive.
Survivorship (Second-to-Die) Policies
A survivorship policy (sometimes called second-to-die or last-to-die insurance) pays the death benefit only when the second of two insureds dies. For a married couple using the unlimited marital deduction under IRC §2056, no federal estate tax is due at the first death; estate tax (if any) is due at the second death. A survivorship policy is timed to provide liquidity exactly when the tax is due.
Survivorship policies are typically owned by an ILIT for the same §2042 reason as single-life policies. The trust holds all incidents of ownership; neither spouse has any retained interest. The death benefit pays into the trust at the second spouse's death and is distributed to children and grandchildren according to the trust terms, outside the gross estate of either spouse.
Survivorship policy premiums are typically lower than single-life premiums of equivalent face value because both insureds must die before the carrier pays. This makes survivorship policies cost-effective for funding estate tax liquidity in larger estates where both spouses are insurable.
Generation-Skipping Transfer (GST) Tax and the ILIT
If the ILIT beneficiaries include grandchildren or more remote descendants, the generation-skipping transfer tax under IRC §2601 may apply. The GST tax is a flat 40% tax on transfers to skip persons (grandchildren or more remote) above the GST exemption ($15,000,000 per person for 2026 under OBBBA).
The grantor can allocate GST exemption to ILIT contributions on Form 709 (gift tax return). With proper allocation, the death benefit (which may be many times larger than the contributions) passes to grandchildren without GST tax because the leverage is captured under the exemption allocation. ILITs designed for multi-generational use (sometimes called Dynasty ILITs) are typically structured with full GST exemption allocation from inception. See our dynasty trust page for the broader multi-generational planning framework.
Common ILIT Use Cases
Estate tax funding for large estates
The classic ILIT use case is for an estate well above the federal estate tax exemption ($15M individual, $30M couple). The ILIT provides liquidity to pay the estate tax due nine months after death without forcing the family to liquidate the underlying estate (closely-held business, family real estate, illiquid investments). The 40% federal estate tax savings on the death benefit itself is a significant additional benefit.
Family business succession
A family business owner can use an ILIT to fund a buy-sell agreement under which non-operating family members sell their inherited stake to operating family members at the owner's death. The death benefit funds the buy-out; the operating family members keep the business; the non-operating family members receive cash. The ILIT structure removes the death benefit from the owner's gross estate.
Equalization among children
A parent who wants to leave the family business to one child (typically the child who works in the business) can use an ILIT to provide equivalent inheritance to other children. The business goes to one child; the death benefit goes through the ILIT to the other children in amounts that equalize the inheritance.
Charitable giving with family-replacement
A parent who wants to leave a significant portion of the estate to charity (and capture the charitable estate tax deduction) can use an ILIT to replace the charitable gift for the family. The estate goes to charity (no estate tax); the ILIT death benefit provides equivalent inheritance for the family (no estate tax because the ILIT is outside the gross estate). The strategy is sometimes called wealth replacement.
ILIT vs SLAT: A Common Comparison
A Spousal Lifetime Access Trust (SLAT) is sometimes used as an alternative or complement to an ILIT. A SLAT is an irrevocable trust drafted with the spouse as a permissible beneficiary, allowing the grantor to retain indirect access to trust assets through the spouse. SLATs are typically funded with assets other than insurance, but a SLAT can also own life insurance.
For a couple where one spouse expects to outlive the other and the surviving spouse will need access to the trust assets, a SLAT may be preferable to a traditional ILIT because the surviving spouse can receive distributions during life. For a couple where neither spouse needs trust access (sufficient outside assets to live on) and the goal is pure estate tax exclusion for the next generation, a traditional ILIT is structurally cleaner. For the full SLAT framework, see our life-insurance-in-an-irrevocable-trust page.
Costs and Ongoing Administration
Typical ILIT setup cost: $3,500 to $7,500 attorney fee. Ongoing administration includes annual Crummey letters (typically $150 to $500 in attorney or trust administrator time), annual gift tax return filing if contributions exceed annual exclusion thresholds for any reason, and policy premium administration (some clients delegate to the trustee, others handle as the grantor through gift deposits to the trust account).
The cost is generally trivial compared to the estate tax savings. A $5,000,000 policy excluded from a taxable estate above the exemption saves approximately $2,000,000 in federal estate tax (40% of $5M). Setup and ongoing costs over 20+ years total well under 1% of the savings. The cost-benefit math is overwhelmingly positive for any family with an estate above the exemption who wants meaningful life insurance.
Frequently Asked Questions
What is an Irrevocable Life Insurance Trust?
An irrevocable trust that owns one or more life insurance policies on the grantor's life. Because the grantor has no incidents of ownership under IRC §2042, the death benefit is excluded from the grantor's federal taxable estate.
What is a Crummey letter?
A notice giving ILIT beneficiaries a temporary right to withdraw their share of any contribution to the trust. The withdrawal right converts the gift from a future interest (no annual exclusion) to a present interest (annual exclusion available). Named for Crummey v. Commissioner, 397 F.2d 82 (9th Cir. 1968).
What is the 3-year rule for ILITs?
Under IRC §2035(a), if the insured transfers an existing life insurance policy to an ILIT and dies within three years, the policy is pulled back into the gross estate. The rule applies only to transfers of existing policies; if the trustee applies for a new policy directly, §2035 does not apply.
Can a married couple use one ILIT for both spouses?
Yes. A single ILIT can own a survivorship (second-to-die) policy paying only at the second spouse's death. Standard structure when the goal is to fund the estate tax due at the second death after the marital deduction defers tax at the first.
Does the death benefit from an ILIT avoid income tax?
Life insurance death benefits are excluded from gross income under IRC §101(a)(1) regardless of who owns the policy. The ILIT structure affects estate tax (excludes the death benefit from the gross estate under §2042), not income tax.
