A Crummey letter is a written notice a trustee sends to each beneficiary of an irrevocable trust after someone contributes money to it, telling the beneficiary they have a short, defined period to withdraw their share of that contribution. The point of the notice is tax treatment: the temporary withdrawal right converts what would otherwise be a “future interest” gift into a “present interest” gift, which is what lets the contribution qualify for the federal annual gift tax exclusion of $19,000 per recipient in 2026.1Internal Revenue Service.

The letter is a formality, but it’s a formality with real tax consequences when it’s missing or done wrong.
Why the Letter Exists
Federal gift tax law excludes the first $19,000 you give to any one person each calendar year, but only if the gift is a present interest, meaning the recipient can use or enjoy it immediately.2Office of the Law Revision Counsel. 26 USC 2503 – Taxable Gifts Money placed in an irrevocable trust usually can’t be reached by the beneficiaries until some future date or event, so the IRS treats it as a future interest gift, which doesn’t qualify.
Without that exclusion, every contribution to the trust either triggers gift tax or eats into the grantor’s $15 million lifetime exemption.3Internal Revenue Service. Whats New – Estate and Gift Tax For a trust that has to be funded every year, such as an irrevocable life insurance trust that pays annual policy premiums, the numbers get large quickly. Giving each beneficiary a brief, enforceable right to withdraw their portion of a new contribution satisfies the present-interest requirement, even though everyone involved expects the money to stay in the trust.
The name comes from the 1968 Ninth Circuit decision in Crummey v. Commissioner, which held that a beneficiary’s temporary right to withdraw was enough to qualify contributions for the annual exclusion.4Justia. D. Clifford Crummey et al. v. Commissioner of Internal Revenue, 397 F.2d 82 (9th Cir. 1968) The ruling stuck, and the technique became standard.
What the Letter Should Say
A Crummey letter doesn’t need to be long, but it does need to be specific. Standard practice is to include:
- The date of the contribution and the exact amount.
- A clear statement that the beneficiary has the right to withdraw a specified dollar amount.
- The exact date by which the beneficiary must act, not just the number of days.
- Instructions for making a withdrawal request, including who to contact and whether the request has to be in writing.
Vague notices create audit risk. If the letter doesn’t clearly communicate the withdrawal right, the IRS can reclassify the contribution as a future interest gift and deny the annual exclusion.
Timing and the Withdrawal Window
Two timing questions matter: when the letter goes out, and how long the beneficiary has to act.
The notice should go out promptly after each contribution, not batched at year-end. The withdrawal right attaches to a specific contribution, so a generic annual letter doesn’t work. Four contributions in a year means four rounds of letters.
The IRS requires that beneficiaries receive actual notice and a reasonable opportunity to exercise the right before it lapses. Several IRS private letter rulings have accepted a 30-day exercise period as sufficient, and many trust agreements set the window at 30 to 60 days. A three-day window has been found so short as to make the withdrawal right essentially meaningless, and the exclusion was denied. Thirty days is the practical floor.
Proving Delivery
Sending the letter is only half the work. If the IRS questions whether beneficiaries actually received notice, the trustee has to prove it. The safest options are certified mail with return receipt, or a signed acknowledgment from each beneficiary confirming receipt. Keep those records indefinitely. Without proof of delivery, the trustee is left arguing years later that the beneficiary somehow knew about a withdrawal right, and that argument rarely holds up in an audit.
Notices for Minor Beneficiaries
A minor obviously can’t read a legal notice and decide whether to withdraw trust funds. The Crummey case itself addressed this: the Ninth Circuit held that a parent, acting as natural guardian, could exercise the withdrawal right on behalf of a minor child.4Justia. D. Clifford Crummey et al. v. Commissioner of Internal Revenue, 397 F.2d 82 (9th Cir. 1968) The IRS later accepted that minors qualify for the annual exclusion as long as nothing in local law or the trust document prevents a guardian from exercising the right.
In practice, the letter for a minor beneficiary should go to the parent or legal guardian, and the trust agreement should explicitly authorize a guardian or conservator to exercise withdrawal rights on the minor’s behalf. If the trust is silent, the IRS has more room to argue the right was illusory.
What Happens When the Window Closes
This is where Crummey trusts get technical. When a beneficiary lets the withdrawal window close, the IRS treats the lapse as though the beneficiary made a gift back to the trust. The logic is that the beneficiary had the right to take the money and chose not to, which is functionally the same as taking it and putting it back.
Federal law provides a safe harbor. A lapsed withdrawal right is only treated as a taxable release to the extent it exceeds the greater of $5,000 or 5% of the trust’s total value.5Office of the Law Revision Counsel. 26 USC 2514 – Powers of Appointment This is the “5-and-5” rule. If a trust holds $200,000, the safe harbor is $10,000. A $19,000 withdrawal right that lapses in that trust exceeds the safe harbor by $9,000, and that excess could be treated as a taxable gift by the beneficiary.
Hanging Powers
Estate planners work around this with a “hanging power.” Instead of the full withdrawal right lapsing at once, the trust document provides that the right lapses each year only up to the 5-and-5 safe harbor amount. Any excess “hangs,” meaning it stays exercisable and carries forward, lapsing gradually in later years as the safe harbor allows. The beneficiary never actually exercises the hanging portion, but its continued existence prevents the immediate gift-tax problem. Most well-drafted Crummey trusts include this feature. Older trusts drafted before hanging powers became standard may not.
What if a Beneficiary Actually Withdraws
Beneficiaries almost never exercise their withdrawal rights, but the right has to be real. If a beneficiary does request the money, the trustee has to distribute it. For an irrevocable life insurance trust, withdrawn funds can no longer pay the policy premium, and the policy may lapse if the trust has no other resources. Family dynamics can shift, too: exercising the right may signal to the grantor that further contributions aren’t wanted.
The trust cannot penalize a beneficiary for exercising the right, and there can’t be any agreement, written or unwritten, that beneficiaries won’t withdraw. If the IRS concludes the withdrawal right was never genuinely available, the whole Crummey structure fails.
Common Pitfalls the IRS Targets
Certain patterns reliably draw IRS scrutiny.
Withdrawal Rights Given to Non-Beneficiaries
Some trusts grant Crummey rights to people with no real stake in the trust just to multiply annual exclusions. After the Estate of Cristofani case, the IRS said publicly it would challenge arrangements where the withdrawal power sits with someone who is only a contingent beneficiary or has no genuine interest, viewing it as evidence of a tacit agreement that no one will withdraw.
Blanket Waivers of Future Notices
A beneficiary cannot waive the right to receive future Crummey notices. The IRS has ruled that when beneficiaries signed blanket waivers, subsequent contributions were not present-interest gifts and the exclusion was denied. Each contribution needs its own notice. Trustees who get sloppy after the first few years of a trust are gambling with every exclusion they claim.
Windows That Are Too Short
The exercise period has to give the beneficiary a real chance to act. A few days is not enough, and neither is a notice sent so late that the window is effectively gone. The IRS asks whether the opportunity was genuine, not just theoretical.
Where Crummey Letters Come Up
The technique is most closely associated with irrevocable life insurance trusts, where the grantor contributes cash each year to cover premiums. Without valid Crummey notices, every premium payment becomes a future-interest gift that either triggers tax or drains the lifetime exemption. Education trusts, dynasty trusts, and special needs trusts use the same approach for the same reason. Because the annual exclusion resets each calendar year, the letter process repeats with every contribution, and missing a beneficiary or skipping a year can unravel the tax treatment for that contribution entirely.
