How Irrevocable Life Insurance Trusts Work for Couples in 2026

What an Irrevocable Life Insurance Trust Is and Why Couples Use One

An irrevocable life insurance trust is a trust that owns a life insurance policy so the death benefit stays outside your taxable estate. Instead of you owning the policy personally, the trust owns it, pays the premiums, and receives the proceeds when the insured dies. Because you never own or control the policy, the proceeds generally aren't counted in your gross estate.

Here's the concrete 2026 takeaway: with the federal exemption at $15 million per individual, most families won't owe federal estate tax. But if your combined estate (real estate, retirement accounts, business interests, and life insurance death benefits) approaches or exceeds $15 million individually or $30 million as a couple, an ILIT remains the primary way to keep a large death benefit from adding to that taxable total.

Deciding to set up an ILIT is a shared planning choice. You and your partner sit down together, look at what you've built, and decide how you want a future death benefit to work for your family. It's about creating clarity now so nobody is scrambling later. Couples whose combined estate is near or above the exemption, or who own illiquid assets like a family business, tend to benefit most.

How Does an ILIT Work Under IRC Section 2042

Section 2042 of the Internal Revenue Code pulls life insurance proceeds into your gross estate if either the proceeds are payable to your estate or you held any "incidents of ownership" in the policy at death. Incidents of ownership is a deliberately broad phrase. It includes the right to change the beneficiary, cancel or surrender the policy, borrow against it, pledge it as collateral, or assign it. Hold any one of those rights, and the death benefit generally comes back into your estate.

That's why the structure matters so much. The trust, not the insured, must own the policy and be its beneficiary. The insured cannot retain any strings that count as control.

One useful way to picture it: think of the ILIT as a box with a lock and a set of instructions. The lock is the irrevocable trust structure. The instructions are the trust terms that say who gets what and when. The insurance policy is the asset inside the box. If the wrong person keeps the key (meaning the insured retains control), the IRS may still treat the death benefit as part of the estate.

Watch the three-year lookback rule. If you transfer a policy you already own into an ILIT and die within three years, the proceeds are still included in your estate under Section 2035. For this reason, having the trust apply for and buy a brand-new policy from the start avoids the lookback problem entirely.

Three roles run the trust:

• Grantor: the person who creates and funds the trust (often the insured or a spouse).
• Trustee: the person or institution that owns the policy, pays premiums, sends required notices, and manages the trust. This should not be the insured.
• Beneficiaries: typically the spouse, children, or grandchildren who receive the proceeds under the trust's terms.

Because the mechanics are exacting and the tax stakes are high, this is work to do with a qualified estate planning attorney.

2026 Estate and Gift Tax Thresholds Couples Should Know

The 2025 One Big Beautiful Bill Act set the federal estate and gift tax exemption at $15 million per individual for 2026, indexed for inflation going forward. That's a meaningful shift from the roughly $13.61 million per person available in 2024 and a very different picture from the reversion many planners had braced for. The IRS estate tax pages track filing thresholds each year.

The annual gift tax exclusion for 2026 is $19,000 per recipient. That's the amount you can give any one person, including a trust beneficiary, without using any lifetime exemption or filing a gift tax return.

Portability lets a surviving spouse use the deceased spouse's unused exclusion, but only if the first estate makes a timely election on a federal estate tax return (Form 706). Miss that election and the unused amount is generally lost. Even a couple that expects to fall well under the exemption sometimes files simply to preserve portability.

A high federal number doesn't make ILITs irrelevant. Several states impose their own estate or inheritance taxes with far lower thresholds than the federal exemption, so a family with no federal exposure can still face a state bill. Add a large death benefit, a family business, or unequal heirs, and the structure keeps mattering.

Funding an ILIT With Crummey Powers

You can't just write a check to the insurance company. Every dollar that pays the premium has to flow through the trust in a way that qualifies for the annual gift tax exclusion. The grantor gifts cash to the trust, and the trustee uses it to pay the premium.

The catch: the annual exclusion under Section 2503(b) applies only to gifts of a "present interest," and a gift to a trust normally isn't one. The fix is a Crummey power, named after a 1968 Ninth Circuit case (Crummey v. Commissioner). The trust gives each beneficiary a temporary right to withdraw their share of the contribution, usually for 30 to 60 days. That withdrawal right converts the gift into a present interest, so it qualifies for the $19,000 exclusion.

To document this, the trustee sends a Crummey letter to each beneficiary every time a contribution is made, notifying them of their withdrawal right. Beneficiaries typically let the window pass without withdrawing, and the trustee then pays the premium. No letters, no qualifying gifts, and the IRS can treat the contributions as taxable gifts that eat into your lifetime exemption.

Two technical points that trip families up:

• The 5-or-5 rule and hanging powers. A lapsing withdrawal right can be treated as a taxable gift by the beneficiary if it exceeds the greater of $5,000 or 5% of the trust's value. Trusts often use "hanging" powers that carry the excess forward across years to avoid this.
• GST exemption tracking. Gifts that fall under the annual exclusion aren't required to be reported on a gift tax return, which means generation-skipping transfer tax (GST) exemption allocation is easy to overlook. Tax practitioners have documented how failing to affirmatively opt in or out of the automatic GST allocation rules, and not tracking exemption use, can undermine a plan meant to benefit grandchildren.

The theme here is discipline. The trust setup is the easy part. It's the year-after-year documentation that keeps the proceeds out of the estate. Professional administration is what prevents an expensive misstep years down the road.

Second-to-Die Survivorship Life Insurance in an ILIT

A survivorship policy (also called "joint last survivor" or "second-to-die" insurance) insures two lives, usually a married couple, and pays a single death benefit only after the second insured dies. Nothing pays out at the first death.

That design keeps premiums lower. Because the carrier doesn't have to pay until both spouses have passed, the expected timeline stretches out, and premiums are generally lower than buying two separate single-life policies for the same total coverage. For couples planning a large death benefit together, that pricing is a real advantage.

Here's why the pairing fits estate planning so well. When the first spouse dies, the unlimited marital deduction usually means no estate tax is due, since assets pass to the surviving spouse tax-free. The tax pressure shows up at the second death, exactly when a second-to-die policy pays out. Holding that survivorship policy inside an ILIT aims to remove the proceeds from both spouses' estates while delivering cash right when the family needs it.

That liquidity matters most for illiquid estates. A common scenario: everything looks fine while both spouses are alive, then the second spouse passes, the estate tax bill comes due, and the family can't liquidate the business or sell a property that's been in the family for generations quickly enough. Tax-free proceeds from an ILIT-owned survivorship policy can cover the estate tax, debts, and administrative costs, and can help replace the marital deduction lost at the second death, without forcing a fire sale of the family business or real estate.

Second-to-die policies inside an ILIT do require careful structuring around valuation and premium timing, so this is a plan to build with an attorney and a CPA rather than off the shelf.

ILIT Pros and Cons and How Neptune Guides Couples Through the Process

An ILIT gives you estate liquidity at death, meaningful creditor considerations for the proceeds, and control over how and when your beneficiaries receive the money. That last point is something an ordinary policy paid directly to heirs can't offer. You set the terms.

The trade-off is right there in the name: irrevocable. Once it's created and funded, you generally can't change it or take the policy back, and you give up control by design (that's what keeps the proceeds out of your estate). It also demands ongoing administrative discipline, the Crummey letters, the recordkeeping, the GST tracking.

This is exactly the kind of decision that benefits from an honest conversation between partners. As Michael C. Cotugno, Esq., Managing Partner, Neptune Legal, puts it: "True strength in any relationship comes not from avoiding uncomfortable truths or difficult conversations, but from confronting them with courage, compassion, and an unwavering commitment to clarity and mutual respect." Planning for what happens at death is one of those conversations, and doing it together tends to bring couples closer.

Neptune manages the full process end to end. We pair you with experienced estate planning attorneys (20+ years), CFPs, and CPAs, then coordinate the moving pieces: the trust drafting, the policy structuring, the funding mechanics, and the annual administration that keeps everything working. Couples who plan together, grow together, and Neptune's role is to shepherd that planning from the first conversation through the ongoing years of a trust that has to be run correctly to do its job.
