What Is an Irrevocable Life Insurance Trust (ILIT)? Protecting Beneficiaries from Taxes
By the PolicyZen Team · Updated March 2026 · 8 min read
Life insurance death benefits are received income-tax free by beneficiaries. That much most people know. What many don't realize: the death benefit is often included in your gross taxable estate — potentially triggering estate taxes at 40% above the federal exemption threshold. An Irrevocable Life Insurance Trust (ILIT) solves this by placing the policy outside your taxable estate entirely.
The federal estate tax exemption is $13.61 million per individual in 2025 (scheduled to be cut roughly in half after 2025 if the TCJA sunsets). For estates that could be affected, a $5M life insurance policy owned outright adds $5M to the taxable estate — potentially creating a $2M estate tax bill on a benefit that was supposed to help heirs. An ILIT removes the policy from your estate.
How an ILIT Works
- An attorney creates an irrevocable trust — you can't modify or revoke it once created
- The ILIT applies for and owns the life insurance policy (you don't own it)
- You make annual premium payments to the trust (using your annual gift tax exclusion, $18,000/person in 2024)
- Crummey letters are sent to beneficiaries notifying them of their withdrawal right (a technical IRS requirement to qualify the gifts)
- At your death, the policy pays to the trust — not your estate
- The trustee distributes benefits to beneficiaries per trust terms, outside probate, outside your taxable estate
The "3-Year Rule" for Existing Policies
If you transfer an existing policy you already own into an ILIT, the IRS requires you to survive at least 3 years for the policy to be fully excluded from your estate. If you die within 3 years of the transfer, the death benefit is pulled back into your estate. For this reason, ILITs typically work best when the trust applies for and owns the policy from inception.
Irrevocable means irrevocable. You permanently give up ownership of, and control over, the policy placed in the ILIT. You cannot borrow against the cash value, change beneficiaries, or reclaim the policy. This is the core trade-off — estate tax savings at the cost of permanent loss of control. This is an estate attorney decision, not a DIY one.
Who Should Consider an ILIT?
- Estates likely to exceed the federal exemption threshold (currently $13.61M, potentially $6–7M after 2025 sunset)
- Business owners with large life insurance policies funding buy-sell agreements
- Individuals with second-to-die policies intended to fund estate taxes
- High-net-worth individuals using life insurance as an estate planning tool
For most Americans — those with estates well under $10M — an ILIT adds complexity without meaningful tax benefit. The federal exemption is generous enough that most households don't face estate tax exposure even with substantial life insurance policies.
Frequently Asked Questions
What is an Irrevocable Life Insurance Trust (ILIT)?
An ILIT is a trust designed to own a life insurance policy, keeping the death benefit out of your taxable estate. When structured properly, the proceeds are paid to the trust (not your estate) and pass to beneficiaries free of federal estate tax. ILITs are primarily used by high-net-worth individuals with estates that may exceed federal or state estate tax exemptions.
Why does life insurance owned by me get included in my taxable estate?
If you own a life insurance policy — meaning you have the right to change beneficiaries, take loans, or surrender the policy — the death benefit is included in your gross estate for estate tax purposes, even though it passes to beneficiaries. An ILIT removes this 'incidents of ownership,' taking the death benefit out of your estate.
What is the 3-year rule for transferring existing policies to an ILIT?
If you transfer an existing life insurance policy to an ILIT and die within 3 years of the transfer, the IRS 'looks back' and includes the death benefit in your taxable estate as if the transfer never happened. To avoid the 3-year rule, the ILIT should purchase a new policy directly rather than accepting a transferred one.
Who should be the trustee of an ILIT?
The insured person should not be the trustee of their own ILIT — this would compromise the trust's purpose of removing incidents of ownership. An independent trustee (a family member, trusted advisor, or corporate trustee) is typically named. The trustee manages premium payments, beneficiary communications (Crummey notices), and eventual distribution of proceeds.
What are Crummey notices and why are they important for ILITs?
Crummey notices are required annual letters sent to ILIT beneficiaries informing them that they have the right to withdraw premium contributions made to the trust (for a limited window, typically 30 days). This withdrawal right is what qualifies premium contributions for the annual gift tax exclusion. Without proper Crummey notices, the IRS may treat contributions as taxable gifts above the annual exclusion.
