Irrevocable Life Insurance Trust (ILIT): Calculate Your Estate Tax Savings
Use this guide to understand the assumptions, inputs, results, and next steps behind the calculator.
An Irrevocable Life Insurance Trust (ILIT) is a sophisticated estate planning tool designed to prevent life insurance proceeds from being counted as part of your taxable estate. For individuals and couples with a net worth exceeding the federal estate tax exemption—projected to be around $7.5 million per person in 2026—an ILIT can potentially save heirs hundreds of thousands, or even millions, of dollars in taxes. This is especially critical as the current, historically high exemption levels are scheduled to be cut nearly in half.
This calculator helps you quantify that savings. It projects your potential federal estate tax liability both with and without an ILIT, factoring in the costs of premiums and trust administration. By comparing these two scenarios, you can determine the net financial benefit of using an ILIT to protect your legacy and provide tax-free liquidity for your beneficiaries. It's designed for those evaluating whether their life insurance needs warrant the creation of a specialized trust.
2026 Estate & Gift Tax Rules: The Post-Sunset Landscape
The primary driver for creating an ILIT is the federal estate tax. For high-net-worth families, 2026 marks a pivotal year. The Tax Cuts and Jobs Act of 2017 (TCJA) temporarily doubled the estate tax exemption, but this provision is set to expire at the end of 2025. This "sunset" will effectively revert the exemption to its pre-TCJA level, adjusted for inflation.
This change means that many more estates will suddenly become subject to the 40% federal estate tax. An ILIT is one of the most effective ways to shield a large, liquid asset—your life insurance death benefit—from this tax.
Here are the key projected figures for 2026 that influence an ILIT's effectiveness:
| Tax Rule | Projected 2026 Amount | Impact on ILIT Strategy |
|---|---|---|
| Federal Estate Tax Exemption | ~$7,500,000 | Estates over this value are subject to tax. An ILIT removes the death benefit from this calculation. |
| Lifetime Gift Tax Exemption | ~$7,500,000 | Unified with the estate tax exemption. Taxable gifts to the ILIT (premiums) reduce this amount. |
| Top Federal Estate Tax Rate | 40% | This is the tax rate applied to every dollar of your estate that exceeds the exemption threshold. |
| Annual Gift Tax Exclusion | ~$19,000 per recipient | Gifts up to this amount can be made to the ILIT each year without using up the lifetime exemption. |
Note: These figures are projections. The calculator's defaults reflect these anticipated changes, which are critical for forward-looking estate planning.
How an ILIT Reduces Your Taxable Estate
The core function of an ILIT is to change the legal ownership of a life insurance policy. When you personally own a life insurance policy, the death benefit is included in your gross estate for tax purposes. If your total estate value exceeds the exemption, your heirs could lose 40% of the insurance proceeds to federal taxes.
An ILIT solves this problem by creating a separate legal entity—the trust—to own the policy. Here’s how the process works:
- Creation: You, the "grantor," work with an attorney to create an irrevocable trust document. You name a trustee (who cannot be you) to manage the trust and beneficiaries to receive the proceeds.
- Funding: You make cash gifts to the trust. The trustee uses this cash to pay the annual premiums on the life insurance policy on your life.
- Ownership: The trust is the owner and beneficiary of the life insurance policy.
- Payout: Upon your death, the insurance company pays the death benefit directly to the trust. Because you did not personally own the policy, the proceeds are not part of your taxable estate.
- Distribution: The trustee manages and distributes the funds to your trust beneficiaries according to the terms you established, free from federal estate taxes.
With vs. Without an ILIT: A Scenario
Consider a widow with a projected taxable estate of $12 million and a $5 million life insurance policy.
- Without an ILIT: Her total taxable estate is $17 million ($12M + $5M). Assuming a $7.5 million exemption, $9.5 million is subject to a 40% tax. The estate tax bill would be $3.8 million.
- With an ILIT: The $5 million policy is owned by the trust. Her taxable estate is only $12 million. With the same $7.5 million exemption, $4.5 million is taxable. The estate tax bill is $1.8 million.
In this scenario, the ILIT saves her heirs $2.0 million in federal estate taxes. This tax-free liquidity can then be used by the beneficiaries to pay the remaining estate tax, buy assets from the estate, or simply serve as their inheritance. It's a crucial part of determining your total retirement needs and legacy goals.
Key ILIT Rules and Considerations
While powerful, an ILIT comes with strict rules that cannot be ignored. The "irrevocable" nature of the trust means you give up significant control.
- Irrevocability: Once you create the trust and transfer assets to it, you generally cannot change the terms, beneficiaries, or trustee. You lose all rights to the policy's cash value and cannot alter the trust's instructions.
- The 3-Year Look-Back Rule: This is a critical IRS provision. If you transfer an existing life insurance policy into an ILIT and pass away within three years of the transfer, the IRS will "look back" and pull the death benefit back into your taxable estate, defeating the purpose of the trust. To avoid this, it's often better for the trustee to purchase a new policy from the outset with funds gifted to the trust.
- Crummey Powers and Gifting: To pay the policy premiums, you must make annual gifts to the trust. For these gifts to qualify for the annual gift tax exclusion ( ~$19,000 per beneficiary in 2026), the beneficiaries must be given a temporary right to withdraw the gifted amount. This is known as a "Crummey power." By using this technique, you can fund significant premiums without eating into your lifetime gift tax exemption, which is a key part of an effective retirement withdrawal strategy for your overall estate.
The Math Behind Your ILIT's Net Benefit
The calculator determines the value of an ILIT by comparing the estate tax outcome in two scenarios and then subtracting the total costs associated with the trust.
The primary calculation is for the potential estate tax liability:
Estate Tax = (Total Taxable Estate - Federal Estate Tax Exemption) × Federal Estate Tax Rate
Where:
- Total Taxable Estate = For the "Without ILIT" scenario, this is your projected estate value plus the life insurance death benefit. For the "With ILIT" scenario, it's just your projected estate value.
- Federal Estate Tax Exemption = The amount you can pass on tax-free (projected at ~$7,500,000 for 2026).
- Federal Estate Tax Rate = The tax rate applied to the estate value above the exemption (typically 40%).
The calculator then determines the net financial benefit after accounting for all costs:
Net Benefit of ILIT = Gross Estate Tax Savings - Total ILIT Costs - Potential Gift Tax Paid
Where:
- Gross Estate Tax Savings = The difference in the estate tax paid between the "Without ILIT" and "With ILIT" scenarios.
- Total ILIT Costs = The sum of all life insurance premiums and annual trust administration fees paid over the life of the trust.
- Potential Gift Tax Paid = Tax due if your taxable gifts to the trust (premiums not covered by the annual exclusion) exceed your lifetime gift tax exemption.
Finally, to assess the impact on your lifetime gift exemption, the calculator figures out how much of each premium payment is a taxable gift.
Annual Taxable Gift = ILIT Annual Premium - (Annual Gift Tax Exclusion × Number of Beneficiaries)
This formula shows why having multiple beneficiaries with Crummey powers is so valuable—it allows you to fund larger premiums without making taxable gifts.
Is an ILIT Worth the Cost and Complexity?
An ILIT is not a "set it and forget it" solution. It requires ongoing management and incurs costs that must be weighed against the potential tax savings.
Key Costs to Consider:
- Legal & Setup Fees: Drafting a proper ILIT document requires a qualified estate planning attorney. These costs can range from a few thousand to several thousand dollars. See our estate planning attorney cost calculator for estimates.
- Life Insurance Premiums: These are the largest ongoing cost and must be paid consistently to keep the policy in force.
- Trustee & Administration Fees: A professional trustee or institution will charge an annual fee to manage the trust, file tax returns (if necessary), and handle Crummey notices. These fees can range from $1,000 to over $5,000 per year.
An ILIT generally makes financial sense when the projected Gross Estate Tax Savings significantly exceeds the total lifetime costs of premiums and administration. If your estate is well below the federal exemption or if the policy death benefit is relatively small, the complexity and expense may not be justified. In such cases, other legacy planning tools, like a straightforward inheritance goal calculator, might be more appropriate.
Frequently Asked Questions About ILITs
What is an Irrevocable Life Insurance Trust (ILIT)?
An ILIT is a type of trust created specifically to own a life insurance policy. By placing the policy inside the trust, the death benefit is legally separated from your personal estate, shielding it from federal estate taxes and providing tax-free funds for your beneficiaries.
Who needs an ILIT?
ILITs are most beneficial for individuals whose net worth is expected to exceed the federal estate tax exemption (projected to be ~$7.5 million in 2026). If your estate, including life insurance, is above this threshold, an ILIT can be a primary tool for reducing your family's tax burden.
Can you change or dissolve an ILIT?
No, the trust is "irrevocable," meaning you cannot easily amend its terms, change beneficiaries, or dissolve it once it's created. This loss of control is the fundamental trade-off for the significant tax benefits it provides.
How are the life insurance premiums paid in an ILIT?
The grantor (the person creating the trust) makes annual cash gifts to the ILIT. The trustee then uses these funds to pay the policy premiums. These gifts must be structured carefully using Crummey powers to qualify for the annual gift tax exclusion and avoid using up your lifetime gift exemption.
ILIT vs. just owning a life insurance policy?
Owning a policy personally is simpler but includes the death benefit in your taxable estate. An ILIT adds complexity and cost but removes the death benefit from your taxable estate, which can result in substantial tax savings for large estates. The right choice depends on your net worth relative to the estate tax exemption.
What happens if the estate tax exemption increases again in the future?
This is a valid consideration. If tax laws change and the exemption rises significantly, an ILIT created solely for tax purposes might become less necessary. However, ILITs can also provide non-tax benefits, such as asset protection for beneficiaries and controlled, structured payouts over time.
Does an ILIT avoid state estate taxes?
Yes, in most cases. States with their own estate tax (which often have much lower exemptions than the federal level) generally follow similar rules regarding policy ownership. An ILIT can typically remove life insurance proceeds from the state-level taxable estate as well. You can check potential liability with an inheritance tax calculator.
Next Steps in Your Estate Plan
Understanding the potential benefits of an ILIT is a critical first step. Use this calculator to model different scenarios with your own numbers. Once you have an estimate, consider the following actions:
- Quantify Your Needs: Determine the appropriate size for your life insurance policy with a life insurance needs calculator. The policy should be large enough to cover estate taxes, provide for heirs, or meet other legacy goals.
- Assess Your Overall Legacy: See how this strategy fits into your broader financial picture. A tool like the how long will my money last calculator can help project the longevity of your assets for both yourself and your heirs.
- Consult a Professional: An ILIT is a complex legal instrument. The next step is always to consult with a qualified estate planning attorney and a financial advisor to design a trust that meets your specific family and financial objectives.
