Irrevocable Life Insurance Trust (ILIT): UHNW Estate Planning Guide

Not tax or legal advice. Verify all figures and strategies with qualified estate counsel before acting.

An Irrevocable Life Insurance Trust (ILIT) solves a specific problem: life insurance is income-tax-free under IRC § 101(a), but if you own the policy at death, the entire death benefit lands in your taxable estate. At a 40% estate tax rate, a $20M policy you own personally delivers only $12M to your heirs. An ILIT owns the policy instead — keeping the death benefit entirely outside your estate.

For UHNW families with the $15M per-person federal exemption (permanently set by the One Big Beautiful Bill Act, July 2025), an ILIT's value proposition has evolved. The estate tax liquidity argument — "we need the policy to pay the bill" — is less urgent for families below $30M per person. At $30M–$200M, the ILIT's role shifts to leveraged transfer (annual premium dollars buying a death benefit at multiples of the premium), estate equalization across heirs, and second-to-die planning for estate tax on the surviving spouse's estate.

How an ILIT works: IRC § 2042

Under IRC § 2042, a life insurance death benefit is included in your taxable estate if either of two conditions exists at your death:

1. The proceeds are payable to your estate or executor.
2. You held any "incident of ownership" in the policy at the time of death.

Incidents of ownership are defined broadly. The IRS includes any economically significant right over the policy:

• Right to change the beneficiary
• Right to surrender or cancel the policy
• Right to borrow against the cash value
• Right to revoke an assignment
• Right to pledge the policy as collateral
• Right to select a settlement option
• Right to assign the policy

An ILIT eliminates § 2042 inclusion by making the trust — not you — the owner and beneficiary of the policy from inception. You hold no incidents of ownership. The trust holds the policy, pays premiums, and collects the death benefit tax-free at your death. Those proceeds are then available to your beneficiaries, or to loan funds to your estate for liquidity, entirely outside the estate tax calculation.

The § 2035 three-year trap

Many families discover this too late: if you transfer an existing policy you own to an ILIT, IRC § 2035 requires the death benefit to be included in your estate if you die within three years of the transfer. The transfer is not ignored — it's just that the estate inclusion rule applies for three years after the gift.²

Example: You own a $15M whole life policy. You transfer it to a newly created ILIT in January 2026. If you die in December 2027 — 23 months later — the entire $15M death benefit is included in your estate under § 2035. The ILIT planning was ineffective.

The correct approach: Have the ILIT apply for a new policy. The ILIT is the applicant, owner, and beneficiary from day one. You are only the insured — you hold no incidents of ownership in the policy. § 2035 never applies because you never owned the policy in the first place.

If you have an existing policy you want to move: The three-year clock runs from the transfer date. Some families transfer the policy anyway and use the three years as a waiting period — maintaining the estate-based structure during the risk window and accepting that the first three years provide no estate-tax exclusion. Others purchase term coverage inside the ILIT to bridge the risk period. Discuss with your estate attorney whether the transfer is worth making given your health and timeline.

Crummey powers: funding premiums with annual exclusion gifts

To fund an ILIT, you must give money to the trust so it can pay insurance premiums. The problem: the annual gift exclusion ($19,000 per recipient in 2026; $38,000 per couple using gift splitting) only applies to gifts of "present interests" — the recipient must have an immediate, unfettered right to use the gift. A gift to an irrevocable trust is normally a gift of a future interest, which does not qualify for the annual exclusion.³

The solution comes from Crummey v. Commissioner (9th Cir. 1968): give beneficiaries a temporary, limited withdrawal right over each contribution. This right — called a "Crummey power" — converts the trust contribution into a present interest for gift tax purposes, qualifying the full contribution for the annual exclusion.

How Crummey notices work in practice:

1. You contribute cash to the ILIT for the annual premium payment.
2. The trustee sends a written "Crummey notice" to each beneficiary, informing them of their right to withdraw their share of the contribution.
3. The notice specifies a withdrawal window — typically 30 to 60 days.
4. Beneficiaries almost never exercise the withdrawal right (if they did, the premium wouldn't get paid). The right lapses at the end of the window.
5. The trustee uses the contributed cash to pay the premium.

The math: With 4 adult children as beneficiaries, each with a $19,000 Crummey right, a married couple can contribute up to $152,000 per year to the ILIT (4 × $19,000 × 2 spouses using gift splitting) with no gift tax and no reduction in lifetime exemption. Add adult children's spouses: 8 beneficiaries × $19,000 × 2 = $304,000 annually. This funds a substantial permanent or whole life policy without touching the $15M exemption.

Hanging powers (§ 2514 five-and-five limit): Under § 2514, a lapsed general power of appointment is a taxable gift by the beneficiary — but only to the extent it exceeds the greater of $5,000 or 5% of the trust assets. A Crummey right that lapses beyond this threshold is a partial taxable gift by the beneficiary. For large trusts with high premium contributions, estate attorneys often use a "hanging power" — structuring the Crummey right to lapse only to the extent of the five-and-five limit in each year, with the excess carrying forward. This avoids inadvertent taxable gifts by beneficiaries while maintaining Crummey treatment for the annual exclusion.

The estate tax math for UHNW

Suppose a 58-year-old couple has an $80M estate — comfortably above the $30M combined exemption. Without planning, the estate faces federal estate tax at 40% on the excess:

The comparison that matters is not "ILIT vs no insurance" but "ILIT-owned policy vs personally-owned policy." In the ILIT scenario, the $15M death benefit arrives outside the estate — zero estate tax on the proceeds. In the personal ownership scenario, the $15M policy adds $15M to the taxable estate and triggers another $6M in estate tax. The ILIT creates a $6M net advantage on this $15M policy — a 40% improvement in transfer efficiency.¹

The leverage angle: At favorable underwriting, a $300,000/year premium (well within Crummey-funded capacity for a large family) can buy a $15–20M whole life death benefit. The present value of those premiums, discounted at 5%, might be $5–6M. The death benefit is $15–20M — a 2.5–3× economic multiplier on the capital committed. For a family with unlimited exemption already utilized, the ILIT offers a high-leverage path to additional transfer that operates entirely outside the gift/estate tax system.

UHNW-specific use cases

Estate equalization across heirs

A common UHNW scenario: one child will inherit the operating business or real estate portfolio; other children will receive financial assets. If the business is the largest asset, the financial-asset children may receive significantly less — or the estate may need to liquidate the business (or take on debt) to equalize distributions.

An ILIT provides a clean solution: life insurance proceeds paid to the ILIT fund equal distributions to the non-business children without forcing a business sale. The business heir inherits the business intact. The policy size is calibrated to the anticipated equalization gap at death.

Second-to-die for estate liquidity at the right moment

Federal estate tax is due nine months after death. Married couples with the marital deduction defer estate tax until the second spouse's death — which is when the bill arrives. A survivorship (second-to-die) policy inside the ILIT pays out at the second death, delivering liquidity precisely when the estate tax check is due. (See the second-to-die section below.)

Funding a buy-sell agreement

For business owners with partners, a cross-purchase or entity-purchase buy-sell agreement often requires life insurance to fund the buyout. If an ILIT owns the policy, the death benefit is outside the business owner's estate while still available to execute the buyout. The ILIT can loan proceeds to the surviving partners or to the estate to facilitate the transaction.

Key-person insurance coordination

At the executive level, key-person insurance is typically owned by the company (not included in the executive's estate). For founders with large equity stakes, separating personal estate planning insurance (in an ILIT) from business-level key-person coverage is part of the advisory coordination role — ensuring the two programs don't create redundant or conflicting objectives.

Second-to-die (survivorship) policies

A survivorship universal life (SUL) or whole life policy insures both spouses' lives but pays out only at the second death. Because the insurer doesn't pay until both insureds die, the mortality cost is lower than a policy on one life — which typically makes the policy significantly more cost-effective per dollar of death benefit.

Why this matches estate planning precisely:

• Federal estate taxes use the unlimited marital deduction — no estate tax is due at the first spouse's death, assuming assets pass to the surviving spouse.
• Estate tax becomes due at the second death, when assets pass to children and the marital deduction is exhausted.
• A second-to-die policy inside an ILIT pays the death benefit at the exact moment the estate tax bill arrives.

Practical considerations:

• If one spouse is uninsurable (health issues), a second-to-die policy may still be underwritten at favorable rates because one healthy spouse is in the policy. The insurer assumes the actuarial risk on both lives in aggregate.
• If the couple divorces, the policy structure needs to be revisited — the trust protector provision should include authority to adjust policy beneficiary designations on divorce.
• Premium funding through Crummey contributions works identically to single-life ILITs.

Premium financing for very large policies

For UHNW families seeking very large death benefits — $50M to $200M+ — annual premiums may exceed practical Crummey contribution limits, or the family may prefer not to shift that much liquidity into the ILIT. Premium financing allows the ILIT to borrow from a lender (typically a private bank or specialty premium finance lender) to pay the premiums.

How it works:

1. The ILIT applies for a large life insurance policy — whole life, universal life, or indexed universal life.
2. A lender (often the same private bank the family uses) loans the ILIT the annual premium amount.
3. The loan is secured by the cash value of the policy and sometimes additional collateral from the family.
4. The ILIT pays interest on the loan, or adds it to the principal balance.
5. At the insured's death, the death benefit pays off the loan balance, and the net death benefit flows to trust beneficiaries.

The economics: The financing works when the policy's internal return (cash value accumulation or IRR at death) exceeds the after-tax cost of the loan. Interest on loans to pay life insurance premiums is generally not deductible, so the comparison is gross loan rate vs. gross policy return. In an environment where loans price at SOFR plus a lender spread, the math depends heavily on the policy type, the insured's age, and underwriting class.

A note on illustrations: Life insurance illustrations project future cash values based on current or assumed credited rates. They are not guarantees. For premium financing analysis, have your advisor stress-test the policy at credited rates 1–2% below the illustration assumption, and at loan rates 1–2% above the projected cost, to ensure the structure remains solvent under adverse scenarios.

Trust design decisions

Trustee selection

Do not name yourself as trustee. The IRS position is that if you retain sufficient control over the trust to direct its management, you hold incidents of ownership in the policy — triggering § 2042 inclusion. The trustee must be genuinely independent.

For smaller ILITs, a trusted family member or friend may serve as trustee. For larger policies or families with complex situations, a corporate trust company provides institutional independence and continuity. In either case, the trustee must send Crummey notices promptly each year and maintain accurate records.

Distribution provisions

At the insured's death, the ILIT receives the death benefit and holds it for beneficiaries. The distribution standard — how and when beneficiaries receive funds — is a design choice. Most UHNW ILITs use a discretionary distribution standard (health, education, maintenance, support, or fully discretionary). The trustee can hold the proceeds, invest them, and distribute over time — providing continued creditor protection and estate planning flexibility for the next generation.

GST planning inside the ILIT

If you want the ILIT's assets to pass to grandchildren and beyond without additional transfer tax, allocate GST exemption to the trust at funding. The allocation appears on Form 709 filed for the year of contribution. Once the trust has a zero inclusion ratio (GST exemption fully allocated), all future distributions to skip persons are GST-exempt — including distributions of the death benefit proceeds at the insured's death.

The math is favorable: you're allocating GST exemption to fund the trust (a relatively small amount — the premium contribution), and the death benefit paid later — which may be many multiples of the premium — passes free of GST. This leverages the GST exemption more efficiently than a direct gift of the same amount.⁴

Trust siting

South Dakota and Nevada are the most common ILIT jurisdictions for UHNW families:

• No state income tax on trust income accumulated inside the trust
• Dynasty trust (perpetual trust) — no Rule Against Perpetuities, so the trust can last for generations
• Directed trust statutes — separate investment direction from administrative trustee duties
• Strong spendthrift provisions — creditor protection for beneficiaries

The family and insured do not need to live in South Dakota. The trust simply needs a South Dakota trustee (or co-trustee) and is governed by South Dakota law.

Crummey notice administration

Crummey notices must be sent for every contribution. This is a hard administrative requirement — failure to send proper notices can result in the IRS disallowing the annual exclusion for the contributions. Most corporate trustees handle this as a standard service. For individually-trusteed ILITs, the trustee must maintain a notice log showing dates sent, withdrawal periods, and written acknowledgments where available.

ILIT vs PPLI: different tools for different objectives

Private Placement Life Insurance (PPLI) and a traditional ILIT are often confused because both involve life insurance inside a trust. They serve fundamentally different purposes:

For a comprehensive UHNW estate plan, both vehicles may coexist: an ILIT provides a $10–20M death benefit for estate tax funding, while a PPLI holds a separate $5–20M alternative investment portfolio for tax-deferred growth. They solve different problems.

Working with a UHNW advisor on ILITs

ILIT planning is a three-discipline coordination problem:

• Estate planning attorney: Drafts the trust to satisfy § 2042 non-inclusion, structures the Crummey powers (including hanging powers for large trusts), determines trust siting, and coordinates GST exemption allocation on Form 709.
• Insurance specialist: Selects the appropriate policy type (whole life, UL, SUL), analyzes underwriting class, and models the death benefit under various premium-funding scenarios. At UHNW scale, accessing institutional pricing (institutional whole life, PPVA, SUL) requires relationships with carriers not accessible through retail channels.
• Fee-only financial advisor: Provides independent analysis of the insurance product — comparing the policy's internal rate of return against alternative uses of the premium capital (taxable investing, SLAT funding, IDGT), stress-testing premium financing scenarios, and integrating the ILIT into the broader estate plan alongside GRATs, SLATs, and IDGT installment sales.

The critical role of the fee-only advisor is independence: advisors compensated on insurance commissions have a financial incentive to recommend the policy. A fee-only advisor who charges a flat retainer or AUM fee has no such incentive — their only obligation is to evaluate whether the policy is the best use of that capital for your specific situation.
