Life insurance in an estate: the ILIT and the three-year rule

Compiled by the Sitonce editorial team from CFP Board sources listed belowUpdated 3 min readFacts verified 1 September 2026
The short answer

A death benefit is included in the estate where the decedent held incidents of ownership. An irrevocable life insurance trust owns the policy instead, keeping the proceeds outside the estate while providing liquidity to pay tax.

Life insurance is income tax free and not estate tax free, and clients regularly conflate the two.

Incidents of ownership

The full death benefit is in the gross estate where the decedent held any of them. The list is broader than owning the policy outright.

  • The right to change the beneficiary.
  • The right to surrender or cancel the policy.
  • The right to borrow against cash value.
  • The right to assign the policy.
  • A reversionary interest exceeding a specified threshold.

Any one of them is enough. A client who transferred a policy but kept the right to change beneficiaries has kept an incident of ownership and has achieved nothing.

The three-year rule

Transferring an existing policy away brings the full death benefit back into the estate if the transferor dies within three years.

The rule exists to prevent deathbed transfers. Its practical consequence is clear: where a new policy is being purchased, the trust should apply for and own it from the outset, so there is never a transfer to claw back.

The three-year rule has no partial credit

Dying in month thirty-five brings the entire death benefit back. There is no proration. That cliff is why the trust-purchases-it-directly route is the standard recommendation rather than one option among several.

The irrevocable life insurance trust

The trust owns the policy and is the beneficiary. The grantor makes gifts to the trust, which the trustee uses to pay premiums.

Proceeds are outside the estate, available to the trust, and the trust can lend to the estate or buy assets from it - providing liquidity to pay estate tax without the proceeds themselves being taxed.

That indirect route is deliberate. A trust obliged to pay the estate's taxes would be treated as an estate asset, so it lends or purchases instead.

Crummey powers

Gifts into a trust are future interests and do not qualify for the annual exclusion. A Crummey power gives each beneficiary a temporary right to withdraw the contribution, converting it to a present interest.

Notice must actually be given, and the withdrawal window must be genuine. A trust where beneficiaries were never notified is a common failure, and it means the exclusion was never available.

When the ILIT is not needed

At a USD 15 million exclusion, most clients have no estate tax exposure and therefore no need for the structure.

It remains useful for a state with a low exclusion, for a very large estate, for a business owner needing liquidity, and for control over how proceeds are used. Recommending one for a client with no exposure is over-engineering, and questions do test proportionality.

Figures are for the 2026 tax year

The transfer tax exclusion was changed by the 2025 reconciliation act and is indexed thereafter. Confirm the current figure before relying on it, and check state law separately.

Common questions

Is life insurance subject to estate tax?

The death benefit is income tax free but is included in the gross estate where the decedent held incidents of ownership - including the right to change the beneficiary or borrow against the policy.

What is the three-year rule?

Transferring an existing policy away brings the full death benefit back into the estate if the transferor dies within three years. There is no proration.

How does an ILIT work?

The trust owns the policy and is the beneficiary, funded by gifts the trustee uses to pay premiums. Proceeds stay outside the estate and can be lent to the estate to provide liquidity.

What are Crummey powers?

Temporary withdrawal rights given to beneficiaries so that gifts into the trust are present interests qualifying for the annual exclusion. Notice must genuinely be given for them to work.

Does every client need an ILIT?

No. At a USD 15 million exclusion most clients have no exposure. It remains useful in low-exclusion states, for very large estates, for business liquidity and for control over how proceeds are used.
