The Irrevocable Life Insurance Trust (ILIT)

Executive Summary

An Irrevocable Life Insurance Trust (ILIT) is a specialized trust designed to own one or more life insurance policies on the life of the grantor (or another insured). Because the trust — not the insured — is the policy owner and beneficiary, the death benefit passes to heirs both income-tax-free and outside the insured’s taxable estate.

For families with substantial estates, business interests, or charitable goals, the ILIT remains one of the most efficient and time-tested vehicles in modern estate planning. It transforms life insurance from a personal asset that may be exposed to estate tax into a leveraged, tax-advantaged engine for liquidity, wealth replacement, and multi-generational planning.

This white paper explains what an ILIT is and how it works mechanically — including a one-page visual of the full funding cycle; why the Crummey power is essential to ILIT funding; the six core benefits ILITs provide, even when federal estate tax exposure is limited; how ILITs integrate with charitable strategies such as wealth replacement for donated assets; the trade-offs, risks, and common implementation pitfalls; a step-by-step process for evaluating and establishing an ILIT; and a glossary of the key terms families will encounter along the way.

What Is an ILIT?

An Irrevocable Life Insurance Trust is a legal entity — a trust — created for the specific purpose of owning life insurance. The trust is established by a grantor (typically the insured), funded with cash gifts to pay premiums, and administered by an independent trustee for the benefit of the grantor’s chosen beneficiaries.

The defining feature is in the name: the trust is irrevocable. Once established and funded, the grantor gives up the ability to amend its terms, reclaim the policy, change the beneficiaries, or access the policy’s cash value directly. This loss of control is the deliberate price of admission for the favorable tax treatment that follows.

The Three Roles in an ILIT

• Grantor: The person who creates and funds the trust. Usually — but not always — also the insured under the policy.
• Trustee: An independent individual or corporate fiduciary who legally owns and administers the policy, sends Crummey notices, and ultimately distributes the death benefit to beneficiaries. The grantor should not serve as trustee, and naming a spouse or beneficiary creates risks worth discussing with counsel.
• Beneficiaries: The individuals (typically children or grandchildren) or charitable entities who ultimately receive the death benefit — either outright or through continuing trust provisions.

Glossary of Key Terms

The following terms appear throughout this paper and in most ILIT engagements. Definitions are simplified for orientation; precise application always depends on the trust document and current law.

Annual Gift Tax Exclusion (IRC §2503(b))

The amount a donor may give each person each year ($19,000 per donee in 2025) without using lifetime exemption or triggering gift tax. Crummey withdrawal rights are what allow ILIT premium gifts to qualify.

Beneficiary

An individual (typically a child or grandchild) or charitable entity entitled to receive trust distributions — in an ILIT, ultimately the death benefit, either outright or in continuing trust.

Charitable Gift Annuity (CGA)

A contract in which a donor transfers assets to a charity in exchange for fixed lifetime payments, with the charity keeping the remainder.

Charitable Remainder Trust (CRT)

An irrevocable trust that pays income to the donor or family for life or a term of years, with the remainder passing to charity. Often paired with an ILIT for wealth replacement.

Crummey Power / Crummey Notice

A beneficiary’s temporary right (commonly 30–60 days) to withdraw a gift made to the trust, and the written notice informing them of that right. Named for Crummey v. Commissioner (9th Cir. 1968), it converts trust gifts into present-interest gifts that qualify for the annual exclusion.

Decanting

Transferring assets from an existing irrevocable trust into a new trust with updated terms — one of the few ways to modernize an aging ILIT.

Donor-Advised Fund (DAF)

A charitable giving account that provides an immediate income tax deduction when funded, with grants recommended to charities over time.

Dynasty Trust

A trust designed to benefit multiple generations — children, grandchildren, and beyond — without incurring transfer tax at each generational level, typically through GST exemption allocation.

EIN (Employer Identification Number)

The federal tax identification number obtained for the ILIT as a separate legal entity, used for its bank account and any required filings.

Estate Liquidity

Cash available to an estate to pay taxes, debts, and administration costs — generally due within nine months of death — without forcing the sale of illiquid family assets.

Five-and-Five (5-and-5) Power (IRC §2514(e))

The rule under which a beneficiary’s lapsed withdrawal right is not a taxable gift to the extent it does not exceed the greater of $5,000 or 5% of trust corpus.

Form 709

The federal gift (and GST) tax return, filed when gifts exceed the annual exclusion or when allocating GST exemption to trust contributions.

Generation-Skipping Transfer (GST) Tax

A 40% federal tax on transfers to grandchildren or more remote generations. Each individual has a GST exemption (equal to the estate tax exemption) that, properly allocated, lets an ILIT operate as a dynasty trust.

Grantor

The person who creates and funds the trust — usually, but not always, the insured under the policy.

Hanging Crummey Power

A withdrawal right that lapses only as fast as the 5-and-5 rule permits, preserving the annual exclusion on larger contributions without creating gift tax issues for beneficiaries.

HEMS Standard

A distribution standard limiting trustee distributions to a beneficiary’s Health, Education, Maintenance, and Support — strengthening creditor protection and tax treatment.

Incidents of Ownership (IRC §2042)

Any retained right in a policy — to change beneficiaries, borrow against cash value, surrender, assign, or pledge it. If the insured holds any at death, the death benefit is included in the taxable estate.

Irrevocable Trust

A trust whose terms generally cannot be amended or revoked by the grantor after signing. Irrevocability is the deliberate price of the ILIT’s estate tax exclusion.

Lifetime Gift & Estate Tax Exemption

The cumulative amount (approximately $13.99 million per individual in 2025) that can pass free of federal gift and estate tax; scheduled to sunset at the end of 2025 absent legislative action.

Present-Interest Gift

A gift the recipient can use or enjoy immediately. Only present-interest gifts qualify for the annual exclusion — the problem the Crummey power solves for gifts in trust.

Probate

The court-supervised process of settling an estate. Death benefits paid to a properly structured ILIT bypass probate entirely.

Reciprocal Trust Doctrine

An IRS doctrine that can unwind the tax benefits of two substantially identical trusts spouses create for each other — a key drafting concern for SLAT-style ILITs.

Spendthrift Clause

A trust provision preventing beneficiaries from assigning their interest to creditors, shielding trust assets from lawsuits and divorcing spouses.

Spousal Lifetime Access Trust (SLAT)

An irrevocable trust naming the non-insured spouse as a discretionary lifetime beneficiary, giving the family indirect access to trust assets while preserving estate exclusion.

Survivorship (Second-to-Die) Policy

A policy insuring two lives that pays only at the second death — aligning the benefit with when federal estate taxes are typically due, often at significantly lower cost than two single-life policies.

Three-Year Lookback Rule (IRC §2035)

If an existing policy is transferred into an ILIT and the insured dies within three years, the death benefit is pulled back into the taxable estate. The reason new policies should be issued directly inside the trust.

Trust Protector

An independent party granted limited powers — such as replacing trustees or modifying administrative terms — to give an irrevocable trust flexibility over time.

Trustee

The independent individual or corporate fiduciary who legally owns and administers the policy, sends Crummey notices, and distributes the death benefit. The grantor should not serve as trustee.

Wealth Replacement

The strategy of using ILIT-owned life insurance to replace, for heirs, the value of assets committed to charity — letting families give more without reducing the family legacy.
