Article Summary
An ILIT is a permanent, irrevocable trust that owns your life insurance policy — removing the death benefit from your taxable estate under both federal and Illinois estate tax law.
Without an ILIT, life insurance proceeds are included in your gross estate even though you named a beneficiary on the policy — because the IRS looks at who had ownership and control over the policy, not who received the money. An ILIT transfers that ownership to the trust, so the death benefit falls outside your taxable estate entirely.
This guide explains what an ILIT is, how it works step by step, who should consider one in Illinois, and what the most common pitfalls are — including the Crummey notice requirement that many families overlook until it is too late.

What Is an Irrevocable Life Insurance Trust (ILIT)?
An irrevocable life insurance trust (ILIT) is a specialized legal arrangement in which a trust — not you — owns your life insurance policy. You create the trust, name a trustee to manage it, and designate beneficiaries who will ultimately receive the death benefit. But crucially, the trust itself holds the policy. You give up ownership and control over the insurance in exchange for a significant tax advantage: when you die, the policy proceeds pass to your beneficiaries without being counted as part of your taxable estate.
The word “irrevocable” is the central defining feature. Unlike a revocable living trust — which you can modify, dissolve, or take assets back from at any time — an ILIT cannot be undone once it is created and funded. You cannot serve as trustee, you cannot change the beneficiaries at will, and you cannot reclaim the policy. This irrevocability is precisely what makes the tax benefit work: the IRS accepts that you have genuinely given up ownership.
Illinois residents use ILITs primarily to address two estate tax thresholds: the Illinois estate tax, which applies to estates exceeding approximately $4 million (as of 2026), and the federal estate tax, which applies to estates exceeding the federal exemption. Because Illinois has a much lower exemption than the federal government, many Illinois families who would not owe federal estate tax still owe Illinois estate tax — making an ILIT particularly relevant for mid-size estates in the $4 million to $13 million range. For a detailed look at how Illinois's estate tax cliff affects planning, see our guide on the Illinois estate tax cliff.
Why Life Insurance Is Often Part of Your Taxable Estate
Many people are surprised to learn that life insurance proceeds — even those payable directly to a named beneficiary like a spouse or child — can still be included in the deceased’s taxable estate. This happens because federal estate tax law (and Illinois follows the same general framework) focuses on incidents of ownership: who had the right to control the policy at death, not who ultimately received the money.
If you owned the policy at the time of your death — meaning you had the right to change the beneficiary, borrow against the cash value, assign the policy, or surrender it — the full face value of the death benefit is included in your gross estate for estate tax purposes. The fact that your beneficiary receives the money directly, bypassing probate, does not remove it from the estate tax calculation.
A common misconception about life insurance and estates
“My life insurance goes directly to my beneficiary, so it’s not part of my estate.” This is one of the most widespread misconceptions in estate planning. Life insurance proceeds bypass probate — meaning they are not distributed through your will — but they are counted in your gross estate for estate tax purposes if you owned the policy. The distinction between probate and estate tax is one of the most important concepts in all of estate planning.
Consider a practical example. An Illinois family has a $6 million estate, including a $1.5 million life insurance policy the deceased owned personally. The full $6 million is potentially subject to Illinois estate tax (which kicks in above approximately $4 million). If instead the $1.5 million policy had been owned by an ILIT, the taxable estate would be only $4.5 million — and the estate tax savings could easily exceed $100,000 depending on where the estate falls on the Illinois rate schedule. For larger estates, the savings are proportionally greater.
It is also worth noting that beneficiary designations on a life insurance policy determine who receives the proceeds — but they say nothing about estate tax treatment. Naming your child as beneficiary means your child gets the money without probate; it does not mean the money is excluded from your estate for tax purposes. Only giving up ownership — through an ILIT or by transferring the policy to the beneficiary directly — accomplishes that.
How an ILIT Works in Illinois
Setting up and operating an ILIT is more involved than creating a standard revocable trust, because the IRS scrutinizes ILITs carefully. The steps must be followed precisely — and maintained year after year — for the trust to achieve its intended tax benefit.
Creating the ILIT
Draft the trust document
An estate planning attorney drafts the ILIT document, specifying the trustee, the beneficiaries, the distribution terms for the death benefit, and the powers and limitations of the trustee. The trust must be drafted carefully to avoid provisions that would give you retained control over the policy — which would cause the proceeds to be pulled back into your taxable estate.
Fund the ILIT with an insurance policy
The ILIT either purchases a new life insurance policy directly (the preferred approach for most clients) or accepts the transfer of an existing policy from you. If you transfer an existing policy, the three-year lookback rule under IRC Section 2035 applies: if you die within three years of the transfer, the proceeds are still included in your estate as though the transfer never happened.
Name the ILIT as both owner and beneficiary of the policy
The trust is listed as the policy owner and the primary beneficiary of the death benefit on the insurance application. This is the step that removes the policy from your estate — because you no longer own it, the proceeds are not included in your gross estate at death.
You remain the insured person
You remain the insured on the policy — your death is what triggers the payout. But the trust owns the policy and collects the proceeds. Being the insured alone, without any ownership rights, does not give you incidents of ownership that would pull the proceeds into your estate.
Funding the ILIT: The Crummey Notice Requirement
Once the ILIT is created, you need to pay the insurance premiums. But you cannot pay them directly — the trust must pay the premiums, because the trust, not you, is the policy owner. The process works like this: you make a cash gift to the ILIT, the trustee sends Crummey notices to the beneficiaries, and then the trustee uses the contributed funds to pay the insurance premium.
The Crummey Notice: Why It Matters
What Happens at Your Death
When you die, the life insurance company pays the death benefit directly to the ILIT — not to your probate estate. Because the trust owns the policy, the proceeds are not part of your gross estate and are not subject to Illinois or federal estate tax. The trustee then manages and distributes those proceeds according to the trust terms. Common distribution structures include:
Immediate outright distribution
The trustee distributes the proceeds immediately to the named beneficiaries — often the simplest approach for families with adult beneficiaries who can responsibly manage a lump sum.
Held in continuing trust
The proceeds remain in the ILIT and are distributed over time — for example, a portion at age 25, another at 30, and the remainder at 35 — useful when beneficiaries include minor children or young adults.
Support for a surviving spouse
ILIT proceeds can be structured to benefit a surviving spouse during their lifetime without being included in the spouse's own taxable estate — though this requires careful drafting to avoid inclusion issues at the second death.
Estate liquidity funding
If the main estate has illiquid assets such as a family business or real estate, the ILIT can loan money or purchase assets from the estate, providing liquidity for estate taxes without forcing a fire sale.
Who Needs an ILIT in Illinois?
Not every Illinois family needs an ILIT. The trust is most valuable — and worth the additional cost and complexity — in specific situations. Here are the strongest indicators that an ILIT belongs in your estate plan:
Your estate (including life insurance) exceeds $4 million
Illinois imposes estate tax on estates above approximately $4 million. If your total assets — including the face value of your life insurance — exceed this threshold, an ILIT can remove the policy value from your Illinois taxable estate and potentially save a significant amount in state estate taxes. The Illinois estate tax rate runs from 0.8% to 16%, making the savings meaningful even for estates only moderately above the exemption.
You are a business owner with significant life insurance
Business owners often use life insurance to fund buy-sell agreements or provide liquidity for their estate's heirs. If that life insurance is owned by the business owner personally, the proceeds land in a potentially taxable estate on top of the business value. An ILIT separates the insurance from the taxable estate while preserving the policy's liquidity purpose for the family and the business.
You have a blended family or complex beneficiary situation
An ILIT gives you control over exactly how insurance proceeds are distributed — by age, by need, by relationship — in ways that a simple beneficiary designation cannot accomplish. For blended families where you want to provide for a surviving spouse without disinheriting children from a prior relationship, a properly structured ILIT can accomplish both goals simultaneously.
Estate planning for blended families in IllinoisYou want to protect insurance proceeds from beneficiaries’ creditors
When a beneficiary receives a direct life insurance payout, that money is generally available to the beneficiary's creditors. If the proceeds are held in an ILIT and distributed at the trustee's discretion, the funds may be shielded from creditors, divorcing spouses, or a beneficiary's poor financial decisions. This asset protection benefit is valuable even for families who do not face estate tax issues.
ILIT vs. Simply Naming a Beneficiary
If you are not facing estate tax exposure, naming a beneficiary directly on your life insurance policy is simpler and perfectly adequate. But for families above the Illinois estate tax threshold, or those with complex beneficiary needs, the comparison looks very different.
Direct Beneficiary vs. ILIT: A Comparison
| Factor | Direct Beneficiary | ILIT |
|---|---|---|
| Included in taxable estate? | Yes — if you owned the policy | No — trust owns the policy |
| Probate? | No — passes directly to beneficiary | No — paid to trust; trust distributes |
| Creditor protection | Limited once received by beneficiary | Strong — trustee holds and distributes carefully |
| Control over distributions | None once paid — lump sum to beneficiary | Full control — by age, need, or conditions |
| Beneficiary changes | Flexible — change the designation anytime | Difficult — trust is irrevocable |
| Illinois estate tax savings | None | Significant — removes proceeds from taxable estate |
| Complexity and cost | Simple and free | Higher — attorney fees, annual administration |
| Best for | Estates below the IL $4M tax threshold | Estates above $4M or with complex beneficiary needs |

Drawbacks and Limitations of an ILIT
An ILIT is a powerful tool, but it is not the right solution for everyone. Before committing to one, Illinois families should understand the genuine limitations involved.
Irrevocability is permanent
Once created, an ILIT cannot be changed, modified, or dissolved by the grantor. You cannot change the beneficiaries without the beneficiaries' consent and careful legal maneuvering. You cannot reclaim the policy or its cash value. Life changes — divorce, beneficiary deaths, new children — can complicate an ILIT that cannot easily be updated. This is why ILIT drafting must anticipate future scenarios with great care.
You cannot serve as trustee
As the grantor, you cannot be the trustee of your own ILIT. Serving as trustee would give you incidents of ownership over the policy, defeating the estate tax purpose. You must choose a trustee who is both trustworthy and capable of managing the contributions, sending Crummey notices, paying premiums on time, and eventually distributing proceeds — all without ongoing court supervision.
Annual administration is required every year
An ILIT is not a create-and-forget tool. Every year, you must contribute funds for the premium payment, the trustee must send Crummey notices to beneficiaries, and the trustee must pay the premium on time. Missing a year or sending defective notices can jeopardize the annual gift tax exclusion and create compliance problems. Some professional trustees charge annual fees for this ongoing work.
The three-year lookback rule for transferred policies
If you transfer an existing policy to an ILIT rather than having the ILIT purchase a new one, IRC Section 2035 pulls the proceeds back into your estate if you die within three years of the transfer. For people in poor health or advanced age, this rule may make the ILIT strategy ineffective for existing policies.
Not necessary for smaller estates
If your total estate — including life insurance — falls well below the Illinois estate tax exemption of approximately $4 million, the cost and complexity of an ILIT likely exceeds the benefit. For these families, correctly naming beneficiaries and keeping the estate plan current is the better approach.
