Imagine a family with $30 million in net worth. The patriarch buys a $10 million whole-life policy, names his children as beneficiaries, and assumes the death benefit will pass to them tax-free. Twenty years later, he dies. His estate is hit with a federal estate tax bill that includes the full $10 million life insurance proceeds — because he owned the policy. With a 40% top federal rate, that single planning mistake cost the family $4 million.
This is the trap that the Irrevocable Life Insurance Trust (ILIT) was designed to prevent. And the strange-sounding "Crummey letter" is the linchpin that lets you fund one without burning through your lifetime gift tax exemption every year you pay a premium.
If you're building serious wealth — or already there — understanding how ILITs and Crummey powers work together is one of the highest-leverage estate planning decisions you can make. This guide walks through the structure, the pitfalls, and the administrative discipline that separates a working ILIT from a paper-only one the IRS will tear apart.
Why Life Insurance Ends Up in Your Taxable Estate
Most people assume life insurance is "tax-free." That's only half the story. The death benefit is generally exempt from federal income tax, but it can absolutely be subject to federal estate tax — and at the top bracket of 40%, the difference is enormous.
Under Internal Revenue Code Section 2042, life insurance proceeds are pulled into the insured's gross estate if either of these is true:
- The proceeds are payable to (or for the benefit of) the insured's estate, or
- The insured held any "incidents of ownership" in the policy at death.
"Incidents of ownership" is a deliberately broad concept. It includes the right to change the beneficiary, surrender or cancel the policy, assign the policy, revoke an assignment, pledge the policy as collateral, or borrow against the cash value. If you, the insured, have any of these powers — directly or indirectly — the death benefit is included in your estate.
The 2026 federal estate tax exemption is generous, but it's also scheduled to keep shifting. For families above the exemption (or those who anticipate growing past it), every dollar of life insurance inside the estate gets taxed at marginal rates as high as 40%. On a $5 million policy, that's $2 million the IRS takes off the top before your beneficiaries see a dime.
The fix: don't own the policy yourself. Have a separate trust own it from inception. That trust is the ILIT.
What an ILIT Actually Is
An Irrevocable Life Insurance Trust is exactly what it sounds like: an irrevocable trust whose primary asset is one or more life insurance policies on the grantor's life. The trustee — typically a family member, attorney, professional fiduciary, or trust company — applies for the policy, owns it, pays the premiums, and ultimately receives the death benefit.
Because the grantor (the insured) doesn't own the policy, none of the Section 2042 "incidents of ownership" attach to them. When the insured dies, the death benefit flows into the trust and out to the beneficiaries — estate-tax-free.
The trust is irrevocable for a reason. The grantor cannot reserve the right to amend, revoke, change beneficiaries, or otherwise call the shots. Reserve any meaningful control and you've just recreated an incident of ownership, defeating the entire purpose.
This irrevocability also creates the central administrative challenge: how do you keep funding the trust to pay premiums without those gifts being treated as taxable transfers?
That's where Crummey powers come in.
The Gift Tax Problem and the Annual Exclusion
The federal gift tax taxes lifetime transfers, with a per-recipient annual exclusion that lets you give a certain amount to each person every year without using your lifetime exemption or filing complications. In 2026, that exclusion is approximately $18,000–$19,000 per donee, depending on year-of-year inflation indexing (confirm the current figure with your advisor).
The critical condition: the annual exclusion is only available for gifts of a present interest — gifts the recipient can use, possess, or enjoy immediately. Gifts of a future interest, where enjoyment is delayed, don't qualify.
A direct contribution to a trust is, by default, a future interest. The beneficiaries can't reach the money right now; they have to wait for distribution events. So in theory, every premium dollar you transfer to an ILIT would chip away at your lifetime gift exemption (and, eventually, trigger gift tax).
For a family paying $50,000 a year in life insurance premiums across an ILIT funded for multiple beneficiaries, that's a problem worth solving.
How the Crummey Power Solves It
The Crummey power — named after the 1968 Ninth Circuit case Crummey v. Commissioner — is a drafting solution. The trust agreement gives each beneficiary the right to withdraw their share of any contribution made to the trust within a limited window (typically 30 days). That withdrawal right transforms what would have been a future interest gift into a present interest gift, qualifying it for the annual exclusion.
Here's how it works in practice:
- The grantor wires premium money to the ILIT trustee.
- The trustee sends a Crummey letter (sometimes called a "Crummey notice") to each beneficiary. The letter says, in effect, "A contribution of Y within 30 days. After that, your withdrawal right lapses."
- The beneficiaries, in nearly every well-run ILIT, decline to withdraw. The reason is implicit: pulling the money out kills the premium payment, which kills the policy, which kills the eventual death benefit far larger than any single year's premium.
- When the withdrawal window closes, the trustee uses the contribution to pay the insurance premium.
Because each beneficiary had a real, present right to take the money, the contribution qualifies as a present interest gift. The annual exclusion absorbs it, and the lifetime exemption stays intact.
The economics depend on having enough beneficiaries with Crummey rights to absorb the annual premium. A trust with five Crummey beneficiaries and a $19,000 per-donee exclusion can absorb roughly $95,000 of premiums per year. Larger families can carry larger policies.
Why "Crummey Letters" Aren't Optional
The notice requirement isn't a formality — it's the substance the IRS will examine. To respect the present-interest treatment, the IRS expects that beneficiaries actually knew about the contribution and the withdrawal window in a way that allowed them to act on it.
Best-practice ILIT administration looks like this:
- Send a written notice for every contribution. Verbal awareness is not enough. Email is generally acceptable; many practitioners still use signed paper for the audit trail.
- Specify the amount and the deadline. "You have 30 days from the date of this notice to demand withdrawal of up to $X."
- Keep delivery proof. Certified mail receipts, signed acknowledgments, or read-receipt email logs.
- File the notices in the trust's permanent records. If the IRS audits a gift tax return or the eventual estate, the trustee must be able to produce them.
- Don't backdate or batch. A single year-end "summary notice" papering over twelve months of premium payments is a red flag.
Several Tax Court cases have allowed ILIT planning to survive challenge precisely because the trustees followed the formalities meticulously. Skipping the notice — or sending it to only some beneficiaries — risks losing the annual exclusion for the entire contribution, which retroactively converts every year's premium into a taxable gift.
The 5-and-5 Rule and the Lapse Trap
There's a subtle wrinkle baked into Crummey powers that catches unwary planners: the lapse of a withdrawal right is itself a gift.
Under IRC Section 2514(e), when a general power of appointment lapses, the powerholder is treated as having made a transfer of the property to whoever ends up benefiting from the lapse — typically the other trust beneficiaries. A Crummey withdrawal right is a general power of appointment. So when a beneficiary lets their right lapse at the end of the 30-day window, the IRS sees a small gift moving from that beneficiary to everyone else.
Section 2514(e) carves out a safe harbor: the lapse is not treated as a taxable gift to the extent it does not exceed the greater of:
- $5,000, or
- 5% of the trust's aggregate value when the lapse occurs.
This is the famous "5-or-5 rule."
Within the safe harbor, lapses are tax-free. Above it, the lapse is a taxable gift by the beneficiary to the other beneficiaries — which, in addition to creating an unexpected tax filing for them, can mess with generation-skipping transfer (GST) tax allocations and even include the lapsed amount in the beneficiary's own estate later.
For ILITs with low cash value (especially in the early years before the policy builds equity), the 5% test produces almost nothing, leaving only the $5,000 floor. If your annual premium per beneficiary exceeds $5,000, the excess Crummey lapse is technically a deemed gift.
Hanging Powers: The Drafting Workaround
Practitioners solve the lapse problem with a hanging power provision in the trust document.
Here's the structure. Each Crummey withdrawal right lapses only to the extent the lapse fits within the 5-or-5 safe harbor. Any excess continues to hang — the beneficiary retains the right to withdraw it in future years, lapsing in $5,000 (or 5%) increments until the entire amount has been safely absorbed.
For a $19,000 annual gift to a single beneficiary in an early-stage ILIT:
- Year 1: $5,000 lapses under the safe harbor; $14,000 hangs.
- Year 2: $5,000 of the prior hangover lapses; another $19,000 contribution comes in, where $5,000 of that lapses; the rest hangs.
- And so on.
Hanging powers eliminate the deemed-gift problem during the beneficiary's lifetime but introduce a different risk: if the beneficiary dies with hanging powers still outstanding, those amounts are included in their gross estate as unexercised general powers of appointment under Section 2041. Trustees and counsel typically monitor hangover balances and may strategically time later distributions or releases to keep things clean.
Some practitioners use a competing approach — a savings clause that nullifies the Crummey power to whatever extent it would be a taxable gift. The IRS has expressed hostility to "savings clauses" that retroactively rewrite the gift, and Tax Court cases have not been kind to them. Hanging powers are the better-tested path.
The Three-Year Lookback: Don't Transfer an Existing Policy
One of the most expensive ILIT mistakes happens at the very beginning. The instinct, especially for families who already own substantial life insurance, is to transfer the existing policy into the new ILIT. That triggers IRC Section 2035.
Section 2035 pulls back into the gross estate any life insurance policy that the decedent transferred (or in which the decedent relinquished incidents of ownership) within three years of death. The reasoning is anti-abuse: people shouldn't be able to dodge Section 2042 by simply re-titling the policy on their deathbed.
If you transfer your $5 million policy to your ILIT today and die two years and eleven months later, the entire $5 million death benefit is right back in your taxable estate — as if you had never set up the ILIT at all.
The cleanest fix is to have the ILIT apply for and purchase a new policy from inception. The trust is the original applicant, owner, and premium payor. The insured is the underwriting subject but never had ownership. Section 2035's three-year clock never starts because there was no transfer.
If a new policy isn't feasible (health changes, age, cost), planners sometimes structure a bona fide sale of the existing policy to the ILIT for adequate consideration. Section 2035 doesn't apply to arm's-length sales. But this introduces a tangle of issues — the transfer-for-value rule under Section 101(a)(2) can make the death benefit taxable as ordinary income to the trust unless the sale fits within an exception. This is not a do-it-yourself maneuver.
Choosing the Trustee
Who serves as trustee is a structural decision, not a personality one. The wrong choice can recreate incidents of ownership and unravel the entire plan.
The grantor must not serve. The insured-grantor as trustee retains de facto control over the policy — the textbook Section 2042 problem.
The grantor's spouse is risky. If the spouse is a beneficiary and has discretionary distribution power, the IRS can argue the spouse-trustee effectively controls the policy for the couple's benefit. Independent trustees are safer.
Adult children can serve, with care. Beneficiary-trustees are workable if the trust limits their distribution powers to an ascertainable standard (health, education, maintenance, support) and they have no power to remove and replace themselves with a non-independent successor.
Professional trustees (banks, trust companies) cost money but eliminate ambiguity. For families with multimillion-dollar policies, the trustee fee is a rounding error compared to the estate tax risk of a botched structure.
A common middle ground: an independent individual trustee (a longtime CPA, attorney, or trusted friend) with a corporate trustee as successor.
Generation-Skipping Transfer Tax Considerations
If the ILIT is designed to benefit grandchildren or skip generations, the GST tax — a separate 40% transfer tax — enters the picture. Contributions need to be either allocated GST exemption (with proper reporting on Form 709) or structured as direct skips that qualify for the GST annual exclusion.
GST allocation in ILITs is a notorious source of errors. The automatic allocation rules don't always cover ILIT contributions the way clients assume, and late or missed allocations can create permanent GST tax exposure on the death benefit. This is a place to insist on a knowledgeable estate planning attorney and to file Form 709 every year regardless of whether you "have to" — the automatic allocation can be turned on or off via election, and a clean paper trail prevents disasters.
Common Mistakes That Wreck ILITs
A working ILIT is mostly about discipline. The common ways they fail:
- Skipping Crummey notices. No notice, no present interest, no annual exclusion — every premium becomes a taxable lifetime-exemption gift.
- Beneficiaries who don't really exist as beneficiaries. Stuffing a trust with "contingent" beneficiaries solely to multiply annual exclusions invites IRS scrutiny. The Cristofani and Kohlsaat cases allow contingent beneficiaries' Crummey rights to count, but the IRS will still challenge purely synthetic arrangements.
- The grantor paying premiums directly to the insurer. Premium funds should go to the trustee, who then pays the carrier. Direct payment can be reconstructed by the IRS as the grantor's continued control.
- Borrowing against the policy. The ILIT trustee can do this; the grantor cannot. Easy to forget once the policy has serious cash value.
- Sloppy or missing records. No corporate book, no notice file, no separate bank account for the trust. The IRS does not respect informal trusts.
- Trustee resignation without replacement. A defunct trustee means no one is sending Crummey notices, paying premiums, or managing the trust. Policies have lapsed for this reason.
Of these, sloppy records are the most common. Premium-paying and notice-sending feels like paperwork. It is. But it is also exactly the paperwork the IRS will demand if your estate is audited a decade from now.
The Bookkeeping Reality
An ILIT is a separate taxpayer. It needs its own bank account, its own tax ID (EIN), and — depending on how it's structured — its own annual income tax filings (Form 1041 if it earns reportable income; usually minimal for a policy-only ILIT). Premium contributions, Crummey notices, beneficiary acknowledgments, trustee fees, and any income or distributions all need to be recorded in a permanent ledger that survives changes of trustee, beneficiary, and decade.
This is exactly the kind of long-horizon, multi-stakeholder record that benefits from a plain-text, version-controlled approach to bookkeeping. When the IRS challenges an ILIT thirty years after formation, what you need is a complete, immutable, human-readable history — not a SaaS export from a vendor that may not exist anymore.
Keep Your Wealth Plans Documented for the Long Run
Estate planning structures like ILITs live for decades and outlast software vendors, accounting firm relationships, and entire careers. As you build out family wealth structures, the records that document them — contributions, notices, premium payments, basis tracking, GST allocations — need to be just as durable. Beancount.io offers plain-text accounting that gives you complete transparency, version control, and zero vendor lock-in for exactly the kind of multi-generation recordkeeping estate plans depend on.
