What Is an Irrevocable Life Insurance Trust?
An irrevocable life insurance trust, commonly called an ILIT, is a trust you create to own and control a life insurance policy. Once the trust is funded and the policy is transferred, you generally cannot change the beneficiaries, take loans against the cash value, or revoke the arrangement. Because you give up incidents of ownership, the death benefit usually stays outside your taxable estate. That keeps the payout away from estate taxes and, in many cases, from creditors and divorcing spouses.

For people with large estates or complex family situations, an ILIT is a planning tool rather than a simple product. It works alongside other estate documents and demands ongoing attention from a trustee who understands the rules.
How an ILIT Works in Practice
You create the trust document, name a trustee, and fund the trust with enough money to pay the premiums. The trust then purchases the life insurance policy, either through a new policy or by transferring an existing one. The trustee manages contributions, pays premiums, and distributes the death benefit according to the trust terms.
Step-by-Step Setup
- Draft the trust agreement with an estate attorney, specifying beneficiaries, trustees, and distribution rules.
- Fund the trust with cash or other assets that can cover premium payments.
- The trust applies for and owns the life insurance policy.
- Premiums are paid from the trust, not from your personal accounts.
- The trustee files any required trust tax returns and tracks the three-year lookback rule for policy transfers.
Key Roles
- Grantor: The person who creates the trust and may also be the insured.
- Trustee: Manages contributions, pays premiums, and makes distribution decisions.
- Beneficiaries: Receive the death benefit according to the trust terms, often in installments or for specific needs.
Benefits of an Irrevocable Life Insurance Trust
The primary benefit is estate tax reduction. In 2025, the federal estate tax exemption is $13.61 million per individual, but state thresholds can be much lower, and exemptions can change. An ILIT keeps the death benefit out of your estate, which protects liquidity for heirs and avoids forcing a sale of assets to pay taxes.
Other advantages include creditor protection, since the trust owns the policy rather than you, and divorce protection, because the death benefit is not marital property if the trust is properly structured. ILITs also let you control how and when beneficiaries receive proceeds, which can prevent spendthrift behavior or probate delays.
Costs and Trade-Offs
An ILIT is not a set-and-forget solution. You lose control over the policy, which means you cannot borrow against the cash value or change beneficiaries without trustee approval. If you die within three years of transferring an existing policy, the IRS may pull the death benefit back into your estate.
Trustees charge fees, and the trust may need its own tax return. Premiums must come from the trust, so you need liquidity planning to keep the policy in force. Mistakes in drafting can turn a tax-saving tool into a taxable event, so professional guidance is essential.
| Factor | Detail | Context |
|---|---|---|
| Estate tax exclusion | $13.61 million per individual (2025) | ILITs matter most when estate value approaches or exceeds this threshold |
| Three-year lookback | Death benefit included in estate if insured dies within 3 years of transfer | Applies to transfers of existing policies; new policies are generally safer |
| Control | Grantor cannot revoke, change beneficiaries, or take loans | Trade-off for estate tax removal and creditor protection |
| Trustee fees | Varies by complexity and trustee type | Corporate trustees cost more but bring expertise |
| State taxes | Many states have lower exemptions or no estate tax | Impact depends on residence and where assets are located |
Who Should Consider an ILIT?
An ILIT makes sense for individuals with estates large enough to face estate taxes, business owners who need liquidity to pay estate taxes without selling the business, and parents or grandparents who want to leave tax-free proceeds to younger beneficiaries or special-needs family members.
It is less useful for people with modest estates well below the exemption, unless they live in a state with a low estate or inheritance tax threshold. Because the rules are strict and the consequences of errors are serious, anyone considering an ILIT should work with an estate planning attorney and a tax professional before moving forward.
