Irrevocable Life Insurance Trust

An irrevocable life insurance trust (ILIT) is an estate-planning device in which a trustee—not the policy owner—holds legal title to a life insurance policy, receives the death benefit upon the insured’s passing, and distributes those proceeds according to the trust terms. Because the insured neither owns nor controls the policy, the death benefit falls outside the taxable estate, escaping the 40% federal estate tax. For high-net-worth individuals, an ILIT can shelter millions of dollars of wealth-transfer value with minimal gift tax cost.

Why life insurance in the estate is a problem

When a person owns a life insurance policy at death, the full death benefit is included in the taxable estate. A $5 million death benefit adds $5 million to the taxable estate. If the estate already uses most or all of the $13.61 million federal exemption (as of 2026), that $5 million is subject to a 40% federal estate tax—a $2 million tax bill funded from the very death benefit intended to provide for family.

This is a costly inefficiency. Insurance is often bought as a wealth-replacement tool—to provide liquidity and capital to heirs, pay debts, or fund charitable gifts. Yet if the owner includes the policy in their taxable estate, the government claims 40% of the benefit before heirs see anything.

The ILIT solves this problem by removing the policy from the insured’s estate entirely. Because the trust, not the person, owns the policy and is listed as the beneficiary, the proceeds do not flow through the insured’s probate estate and are not included in the insured’s taxable estate for federal tax purposes.

Structure: who owns, who controls, who receives

An ILIT is a trust created during the life of the insured (the “grantor” or “settlor”). The grantor transfers ownership of an existing policy to the trust or funds the trust to purchase a new policy. The trust, not the grantor, is the owner and beneficiary.

A trustee—often a professional corporate trustee, a family member, or a co-trustee arrangement—holds and administers the policy. The trustee collects the death benefit at the insured’s death and distributes it according to the trust document. The grantor must relinquish all control: no power to change beneficiaries, surrender the policy, borrow against it, or receive distributions. The moment any of these powers are retained, the policy inclusion in the estate tax is not avoided.

The trust can name multiple beneficiaries—the insured’s spouse, children, or more distant descendants. A common structure names the spouse as primary beneficiary and children as remainders, allowing the spouse to access funds if needed, with any surplus remaining for children.

The funding mechanism: premiums and the annual exclusion

The ILIT does not fund itself. Someone (typically the insured, or a family member on their behalf) must donate money to the trust each year to pay the policy premiums. These donations are gifts.

If a parent donates $25,000 to the ILIT each year to pay premiums on a $1 million policy, the $25,000 is a taxable gift unless it qualifies for the annual exclusion. Ordinarily, gifts to trusts do not qualify for the annual exclusion because the beneficiary has no present right to the money. But an ILIT uses a workaround: Crummey letters.

A Crummey letter (named after a tax case) is a notice sent to each trust beneficiary stating that they have a limited window—typically 30 days—to withdraw their pro-rata share of the contribution. If a parent puts $25,000 in an ILIT with two children as beneficiaries, each child receives a letter saying they can withdraw $12,500 within 30 days. In practice, beneficiaries rarely (if ever) exercise this right, but the existence of the withdrawal right qualifies the contribution for the annual exclusion. The parent can exclude $18,000 per beneficiary (as of 2026) from gift tax, even though the money goes to the trust.

If the ILIT has two children as beneficiaries, a parent could fund $36,000 per year ($18,000 × 2), all excluded from gift tax. Over a 20-year period, that is $720,000 in tax-free funding of a policy that might pay out $5 million at death—a powerful multiplier effect.

Three-year rule and incidents of ownership

The ILIT rules contain a critical timing trap: the three-year rule. If the insured owns a policy and then transfers it to the ILIT within three years of death, the entire death benefit is pulled back into the taxable estate. This is a strict rule with no exceptions.

The solution is to plan early. An insured who is in good health should establish the ILIT and transfer an existing policy (or fund the trust to purchase a new policy) as far in advance as possible. If the insured passes more than three years after the transfer, the benefit is safely excluded. For someone with a terminal diagnosis, the three-year rule is already unavoidable, so funding the ILIT after diagnosis provides no estate tax benefit.

Incidents of ownership are equally important. If the insured retains any incidents—power to change beneficiaries, right to borrow against the policy, power to surrender or assign it—the benefit is included in the estate. The trust agreement must explicitly deny the grantor any such powers.

Tax treatment of distributions and income

Once the trust owns the policy, the annual premiums are paid by trust assets. If the trust is funded each year with cash gifts from family members, that cash flows to the trustee, who directs it to the insurance company. The trust itself does not pay income tax on the policy; inside a policy, earnings are tax-deferred.

At the insured’s death, the death benefit is paid to the trust tax-free (life insurance proceeds are income-tax-free). The trustee then distributes the proceeds to beneficiaries. Beneficiaries do not pay income tax on distributions (the proceeds were already tax-free). However, if the trustee retains proceeds in the trust and the trust earns interest or other income, that income is taxable to the trust or beneficiaries under ordinary trust taxation rules.

Distributions from the trust to beneficiaries may have estate tax consequences for the beneficiaries themselves if the trust gives them power over the assets. A trust that distributes insurance proceeds outright to a beneficiary is simple; a trust that holds proceeds in further trust for a beneficiary, with power of appointment, can create tax complications. Professional drafting is critical.

Coordination with overall estate planning

An ILIT is often one component of a larger estate-planning strategy. For a couple with a $25 million estate and $13.61 million exemption each, an ILIT can fund a $5 million policy to provide liquidity for estate taxes, charitable bequests, and family wealth. When the first spouse dies, the ILIT proceeds can fund the surviving spouse’s needs and preserve the marital deduction. When the surviving spouse dies, the ILIT distributes to the next generation tax-free.

An ILIT can also coordinate with dynasty trusts and GST exemption allocation. If the ILIT is structured to benefit grandchildren or more distant descendants, GST exemption should be allocated to the trust. The premium gifts can be made using both spouses’ annual exclusions (via gift splitting) and, for amounts exceeding the exclusion, both spouses’ lifetime exemptions.

Common pitfalls and administrative duties

A frequent mistake is retaining control. If the insured reserves the right to approve trustee decisions, access the cash surrender value, or change beneficiaries, the policy remains in the taxable estate. The grantor must truly relinquish power—the trustee acts independently.

Another error is using the insured as trustee. If the insured is also the trustee and makes investment decisions for the trust or approves distributions, the IRS may argue the insured retained practical control, voiding the estate tax benefit. Best practice is to appoint a corporate trustee or a family member (not the insured) as trustee, or a co-trustee arrangement where an independent party has a veto over certain decisions.

Administrative neglect is common. A trustee must:

• Maintain accurate records of contributions and Crummey withdrawal periods
• Send Crummey letters annually and retain evidence of delivery
• File Form 3520 (if required) to report trust creation and transfers
• File Form 3520-A annually (if the trust is a grantor trust) to report income and distributions
• Ensure the trust holds legal title to the policy and is the designated beneficiary

Failure to follow Crummey procedures—forgetting to send letters one year, or failing to document delivery—can disqualify gifts in that year from the annual exclusion, creating unexpected gift tax exposure.

Divorce also complicates an ILIT. If the insured divorces, the ex-spouse may remain named as a beneficiary or retain withdrawal rights unless the trust document is amended. A thorough estate plan review is warranted after divorce.

The three-generation leverage

An ILIT’s true power emerges across three generations. A parent funds the ILIT with annual gifts, the policy pays at the parent’s death, and the trustee distributes to children and grandchildren. If the trust is properly drafted with GST exemption allocation, the proceeds can skip a generation (from grandparent to grandchild) with no generation-skipping transfer tax. The death benefit becomes free wealth for grandchildren, untouched by any form of federal estate or transfer tax.
