Why Is the Irrevocable Life Insurance Trust (ILIT) a Common Estate Tax Planning Tool for High-Net-Worth Families?

When can life insurance proceeds raise your estate tax? How an irrevocable life insurance trust (ILIT) works, who it fits under the 2026 exemption, and key rules.

For families with significant assets, passing wealth smoothly to the next generation while keeping estate tax as low as possible is a core part of legacy planning. Life insurance is often used for this purpose because it delivers a large lump sum of cash when the insured dies. What many people don’t realize is that if the policy is owned the wrong way, the death benefit itself can be counted as part of the estate and end up increasing the estate tax bill.

The irrevocable life insurance trust (ILIT) is designed to address exactly this problem. Put simply, it is a trust set up specifically to own a life insurance policy, and once it is established, the person who created it generally cannot change or revoke it. For families who expect their estate to exceed the estate tax exemption, an ILIT is one of the more commonly used planning tools.

Which tax does an ILIT help avoid on life insurance proceeds?

Life insurance death benefits are generally not subject to federal income tax, but estate tax is a different matter. Under Internal Revenue Code Section 2042, if the insured held any “incidents of ownership” in the policy at death (for example, the right to change the beneficiary, surrender the policy, or borrow against it), or if the proceeds are payable to the insured’s own estate, the death benefit is included in the gross estate (the total value of everything the person owned at death), which can increase the estate tax owed.

How many families this actually affects depends on the size of the estate. In 2026, the federal estate and gift tax lifetime exemption is $15 million per person (the level set by the tax law passed in July 2025), and a married couple can shelter up to $30 million combined (provided the surviving spouse makes the portability election to carry over the first spouse’s unused exemption); amounts above the exemption are taxed at a top rate of 40%. So for families whose total assets, including insurance proceeds, are well below that level, federal estate tax is usually not the main concern. But consider a single person with $12 million in assets plus a $5 million policy held in their own name: the estate totals $17 million, and the roughly $2 million above the exemption, taxed at 40%, produces about $800,000 in federal estate tax. If that policy were held in an ILIT instead, that $800,000 could in principle be avoided.

How does an ILIT work?

An ILIT works by moving ownership of the policy out of the insured’s name and into the trust. The process usually involves these steps:

  1. Establish the trust: The person creating the trust (the grantor or settlor) sets up an irrevocable trust and names a trustee (the person or institution responsible for managing trust assets according to the trust document) and beneficiaries (usually the grantor’s spouse and children). To keep the proceeds out of the estate, the insured generally should not serve as trustee.

  2. Transfer or purchase the policy: The grantor can gift an existing policy to the ILIT, or the ILIT can apply for and own a new policy from the start. The difference between the two is explained below under the “three-year rule.”

  3. Pay the premiums: The grantor typically gifts cash to the ILIT each year, and the trustee uses it to pay the premiums. So that these gifts qualify for the annual gift tax exclusion, the trust usually gives beneficiaries a Crummey withdrawal right, meaning the right to withdraw the contribution for a short window (typically about 30 days), and the trustee notifies the beneficiaries in writing. For 2026, the annual gift tax exclusion is $19,000 per recipient. Amounts above that must be reported on Form 709 and generally just use up part of the lifetime exemption.

  4. Death benefit: When the insured dies, the insurance company pays the death benefit directly to the ILIT as the policy’s owner and beneficiary.

  5. Excluded from the taxable estate: Because the policy belongs to the trust rather than the insured at death, and as long as the three-year rule described below is also satisfied, the proceeds are not included in the insured’s taxable estate.

  6. Trust administration and distribution: The trustee manages the proceeds according to the trust document and distributes them to the beneficiaries. The trust can specify the timing, conditions, and manner of distributions, such as paying out in installments or restricting funds to purposes like education.

Why is an ILIT a commonly used planning tool?

  • Keeps the death benefit out of the taxable estate: This is the ILIT’s central function, and the example above shows its effect.

  • Provides liquidity: Estate tax is generally due within nine months of death, and many families’ main assets are real estate or business interests that cannot be sold quickly. The proceeds received by the trust can help the family pay estate tax, settle debts, or support heirs without being forced to sell assets at a discount. In practice, an ILIT typically buys assets from the estate or lends money to it rather than paying the estate’s taxes directly, since doing so could pull the proceeds back into the estate; this needs to be spelled out in the trust terms. As for capital gains tax, inherited assets generally receive a new cost basis equal to their market value at death (a “step-up in basis”), so the inheritance itself usually does not trigger that tax.

  • Asset protection: If the trust document includes a spendthrift clause (a provision that prevents beneficiaries from transferring or pledging their interest in the trust), trust assets in most states can be shielded to some degree from the beneficiaries’ creditors. The extent of protection depends on state law and how the trust is drafted.

  • Distribution according to the grantor’s wishes: Although the trust is irrevocable, the grantor can set out in detail how the proceeds will be distributed when the trust is created, so the wealth passes to the next generation as intended.

  • Avoids probate: Probate is the court-supervised process for settling an estate, and in California it is often lengthy, expensive, and a matter of public record. Proceeds paid to a trust do not go through probate. That said, a policy with a named individual beneficiary already bypasses probate, so the added value of an ILIT here lies mainly in the control it provides over how the money is used.

What to watch for when setting up and managing an ILIT

Once the trust is established, it is very difficult to change. Gifts to the trust must be evaluated for gift tax and generation-skipping transfer tax (GST tax, a separate tax on transfers to grandchildren or other beneficiaries who skip a generation; the 2026 GST exemption is also $15 million per person). Crummey notices must also be sent on time and correctly each year, or the annual gift exclusion may be disallowed.

If an existing policy is transferred to an ILIT, the “three-year rule” (Section 2035) also applies: if the grantor dies within three years of transferring the policy, the proceeds are still included in the estate. Having the ILIT purchase a new policy as the original owner generally avoids this issue.

For families whose assets and members are spread across countries (for example, the U.S. and China), planning becomes more complex. A spouse who is not a U.S. citizen, for instance, does not qualify for the unlimited marital deduction, which requires separate arrangements. Estate tax rules and exemptions for non-U.S. residents also differ significantly from those for U.S. citizens and green card holders, and countries differ in how they recognize and tax trusts, so the design needs to reflect each family member’s status and where the assets are located.

How to decide whether an ILIT is right for you

Start with three questions. First, once the insurance proceeds are added to your other assets, could your total estate exceed the 2026 exemption of $15 million per person ($30 million per couple), or does your family have special circumstances such as a non-citizen spouse or cross-border assets? If your estate is well below the exemption, an ILIT’s estate tax value is limited, and the question becomes whether its control and protection features justify the cost of setting it up and maintaining it. Second, are you comfortable with the trust being irrevocable and no longer controlling the policy yourself? Third, are you willing to maintain the trust properly over the long term, including annual Crummey notices and any required gift tax filings? If the answers lean toward yes, an ILIT deserves serious consideration. You are welcome to contact Meta Mega Group to review it in the context of your family’s situation.
