Life insurance proceeds paid to a trust are generally not taxable as income, no matter how large the policy.1Office of the Law Revision Counsel. 26 USC 101 – Certain Death Benefits The harder questions sit on either side of that clean rule: whether the death benefit gets dragged into the insured’s taxable estate, and what happens to the money once the trust invests it. Both can produce real tax bills, and both turn on how the trust was set up.
The Death Benefit Itself Is Income-Tax-Free
Federal law excludes life insurance death benefits from the recipient’s gross income.1Office of the Law Revision Counsel. 26 USC 101 – Certain Death Benefits It doesn’t matter whether the beneficiary is a person, a trust, or the insured’s estate. A $500,000 policy and a $10 million policy get the same treatment. The full death benefit arrives in the trust free of federal income tax.
One small exception catches trustees off guard. Any interest the insurer credits between the date of death and the date it actually cuts the check is ordinary taxable income.2Internal Revenue Service. Life Insurance and Disability Insurance Proceeds The amount is usually modest, but it needs to go on the trust’s income tax return.
Estate Tax Is the Real Risk
Escaping income tax does not automatically mean escaping estate tax. Under federal law, life insurance proceeds are pulled into the insured’s gross estate in two situations: the proceeds are payable to or for the benefit of the estate, or the insured held any “incidents of ownership” in the policy at death.3Office of the Law Revision Counsel. 26 USC 2042 – Proceeds of Life Insurance
An incident of ownership is any right to control the policy’s economic benefits. Changing the beneficiary, surrendering or canceling the policy, borrowing against its cash value, pledging it as collateral, or holding a reversionary interest worth more than 5% of the policy’s value all qualify.4eCFR. 26 CFR 20.2042-1 – Proceeds of Life Insurance The right doesn’t have to be exercised. Simply holding it is enough to pull the entire death benefit into the estate.
If the insured serves as trustee of their own life insurance trust, or if the trust document gives the insured any power over the policy, the IRS treats the insured as still owning it for estate tax purposes. The result is the same as if the trust had never been created.
How Much That Costs
For 2026, the federal estate tax exemption is $15 million per individual, set and indexed for inflation by the One, Big, Beautiful Bill signed into law on July 4, 2025.5Internal Revenue Service. Whats New – Estate and Gift Tax A married couple using portability can shelter up to $30 million combined. Below that threshold, inclusion costs nothing in federal estate tax. Above it, every included dollar is taxed at marginal rates reaching 40%.6Office of the Law Revision Counsel. 26 USC 2001 – Imposition and Rate of Tax
For someone with a $20 million estate and a $5 million policy, inclusion means roughly $2 million in additional federal estate tax. That is the number that drives most ILIT planning.
The Three-Year Lookback
Transferring an existing policy into a trust does not produce instant results. If the insured dies within three years of the transfer, the full death benefit snaps back into the gross estate as if the transfer never happened. The lookback hits the entire death benefit, not just the premiums paid during those three years. Congress specifically carved life insurance transfers out of the small-transfer exception that protects most other gifts from this rule.7Office of the Law Revision Counsel. 26 USC 2035 – Adjustments for Certain Gifts Made Within 3 Years of Decedents Death
The clean workaround is to have the trust apply for and own the policy from day one. When the trust is the original applicant and owner, the insured never technically held the policy and the three-year clock never starts.
What an ILIT Does to Prevent Inclusion
An Irrevocable Life Insurance Trust is the standard tool for keeping proceeds out of the taxable estate. It owns the policy and receives the death benefit, so the insured never holds any of the rights that trigger inclusion. Three structural features make it work:
- Irrevocability. The grantor cannot amend or revoke the trust. Retaining the power to revoke would itself be an incident of ownership.
- Independent trustee. Someone other than the insured or the insured’s spouse must hold and exercise all ownership rights over the policy.
- No retained control. The insured cannot hold any power that looks like control, even indirectly. Serving as an investment advisor to the trust, or holding a power to remove and replace the trustee with a related party, can be enough to cause problems.
Corporate and professional trustees charge annual fees to administer the trust, and those costs run for the life of the policy. For large policies the estate tax savings dwarf the administrative expense; for smaller ones the math is closer.
Income Tax on What the Trust Earns Afterward
The death benefit arrives tax-free, but the moment the trustee invests the proceeds, any income those investments generate is taxable. And trusts face compressed income tax brackets that reach the top rate almost immediately. For 2026, a trust hits the 37% federal bracket at just $16,000 of taxable income.8Internal Revenue Service. Revenue Procedure 2025-32 An individual doesn’t reach that rate until well over $600,000. The full 2026 trust schedule:
- 10% on the first $3,300 of taxable income
- 24% from $3,301 to $11,700
- 35% from $11,701 to $16,000
- 37% on everything above $16,000
A $2 million death benefit invested at 5% generates $100,000 in annual income. Kept inside the trust, the federal income tax on that would run around $34,950. The trustee can cut that bill by distributing income to beneficiaries, who then report it on their own returns at their individual rates. The trust claims a distribution deduction for whatever income it pays out, shifting the tax to lower-bracket beneficiaries.9Internal Revenue Service. 2025 Instructions for Form 1041 and Schedules A, B, G, J, and K-1 Whether to distribute or accumulate is one of the most consequential ongoing decisions the trustee makes.
Generation-Skipping Transfer Tax
If the trust benefits only the grantor’s spouse and children, the generation-skipping transfer tax never enters the picture. It becomes relevant when the beneficiaries include grandchildren or later generations. The GST tax applies at the maximum estate tax rate, currently 40%.10Office of the Law Revision Counsel. 26 USC 2641 – Applicable Rate
Each individual has a GST exemption equal to the estate tax exemption, which is $15 million for 2026.11Office of the Law Revision Counsel. 26 USC 2631 – GST Exemption A grantor who allocates a small slice of exemption to cover each year’s premium can shelter the entire eventual death benefit from GST tax across generations.
The allocation is not automatic for most life insurance trusts. A transfer only gets an automatic zero inclusion ratio if the trust benefits a single individual during that person’s lifetime.12Office of the Law Revision Counsel. 26 USC 2642 – Inclusion Ratio Since life insurance trusts usually name several beneficiaries, the grantor must affirmatively allocate GST exemption on Form 709 each year contributions are made. Skipping that step, or assuming it happens automatically, is one of the more expensive mistakes in this area.
State Estate and Inheritance Taxes
Federal planning is only half the picture. Roughly a dozen states and the District of Columbia impose their own estate taxes, many with exemptions far below $15 million. State exemptions range from about $1 million to the full federal amount, with most clustered between $1 million and $7 million. A handful of states also impose inheritance taxes, where the rate depends on the beneficiary’s relationship to the deceased; non-relatives face the steepest rates and surviving spouses are generally exempt.
A trust structured correctly to avoid federal estate tax inclusion should also keep the proceeds out of the taxable estate for state purposes, but state rules vary. In a state with a $2 million threshold, even a modest policy can push an estate over the line, so the structure needs to be confirmed under the applicable state’s law.
