A valid Crummey letter has to do five things: name the exact contribution amount, give the date of the contribution, state the beneficiary’s right to withdraw that amount from the trust, specify the calendar date the right lapses, and explain how to exercise it (typically a written demand to the trustee). It also has to reach the beneficiary — or the guardian of a minor or incapacitated beneficiary — promptly after each contribution, with proof you can produce in an audit. Meeting every one of these Crummey letter requirements is what converts a gift into an irrevocable trust from a future interest into a present interest eligible for the $19,000 annual gift tax exclusion in 2026.1Internal Revenue Service. What’s New — Estate and Gift Tax
Why the Letter Has to Exist at All
The annual exclusion under IRC Section 2503(b) only applies to gifts of a “present interest” — property the recipient can use or enjoy right away.2Office of the Law Revision Counsel. 26 USC 2503 – Taxable Gifts A contribution to an irrevocable trust normally fails that test, because the beneficiary cannot touch the money until the trust terms allow a distribution. A Crummey power fixes this by giving the beneficiary a temporary, legally enforceable right to pull the contributed amount out of the trust immediately after each gift. The right itself — not whether anyone exercises it — is what makes the gift a present interest. The Crummey letter is the evidence that the beneficiary was actually told the right existed. Without that evidence, the IRS’s position under Revenue Ruling 81-7 is that the right was effectively postponed and the gift is a future interest, which means no annual exclusion.
The stakes are concrete. A defective notice can force the gift against the grantor’s lifetime exemption, or, once that exemption is used up, trigger an actual gift tax bill at 40%.
What the Letter Must Contain
Each notice has to stand on its own. The beneficiary should be able to read it and know, without hunting down anything else, exactly what they can demand and by when. At minimum, include:
- The exact dollar amount contributed and available for withdrawal.
- The date the contribution was deposited in the trust, which anchors the withdrawal period.
- A clear statement that the beneficiary has the right to demand immediate distribution of that amount (or the portion subject to the Crummey power, if the trust limits it to less than the full contribution).
- The specific calendar date the right lapses.
- Instructions for exercising the right — whom to contact and what form the demand must take, typically a written request to the trustee.
- The identity of the donor, which matters when a trust takes contributions from more than one grantor or when spouses are splitting gifts.
Vagueness is where challenges start. A letter saying only that “a contribution was made to your trust,” with no amount, or one that leaves out the lapse date, gives an examiner room to argue the beneficiary never had meaningful notice. Treat the letter as a document that has to work in isolation, years later, in front of someone looking for a reason to disallow the exclusion.
Timing and Proof of Delivery
The notice has to go out promptly after each contribution. Not batched at year-end, and not sent before the gift actually arrives in the trust. A letter dated weeks after the deposit opens the question of whether the beneficiary had a reasonable opportunity to withdraw before the window closed. Within a few business days of the contribution is the safe practice.
Delivery method matters almost as much as content, because in an audit the trustee carries the burden of proving the beneficiary received the notice. Three methods hold up:
- Certified mail, return receipt requested. The signed green card is hard evidence of the delivery date.
- Hand delivery with a signed, dated acknowledgment on a copy of the notice. The trustee keeps the original.
- Email with a written acknowledgment reply from the beneficiary. A passive read receipt alone is weaker than a reply confirming receipt.
Regular first-class mail is risky. With nothing to show the letter arrived, the trustee has nothing to show the examiner. If the IRS concludes a beneficiary never received notice, the annual exclusion for that beneficiary’s share is denied and the gift is charged against the grantor’s lifetime exemption.
How Long the Withdrawal Window Must Stay Open
Neither the Code nor the regulations fix an exact number of days. The standard is a “reasonable period” for the beneficiary to exercise the right after receiving notice. Most planners use 30 to 60 days, and the IRS has accepted 30 days as sufficient in published guidance and private rulings. Shorter windows have been upheld in some cases but carry needless risk.
The trust document sets the period, and the letter has to report whatever the trust says, converted into a specific calendar date. During the open window the trustee has to keep enough liquid assets on hand to honor a withdrawal demand. A trust that moves every dollar into illiquid real estate the day after a contribution makes the withdrawal right look illusory even when the letter was flawless.
Notice to Minors and Incapacitated Beneficiaries
The Crummey court held that a minor’s inability to sue does not destroy the withdrawal right, because a parent or court-appointed guardian can make the demand on the child’s behalf.3Justia Law. D. Clifford Crummey v. Commissioner of Internal Revenue When the beneficiary is a minor, deliver the Crummey letter to the legal guardian, or to a natural guardian — usually a parent. The same principle covers adult beneficiaries who lack legal capacity; the notice goes to the conservator or legal representative.
One wrinkle catches people. If the trustee is also the minor’s parent, the trustee is essentially notifying themselves of a right they could exercise on the child’s behalf. Courts have not treated this as automatically disqualifying, but it does invite harder scrutiny of whether the parent-trustee genuinely considered exercising the power. A brief memo in the trust file documenting the decision not to withdraw helps show the right was taken seriously.
Records to Keep for the Audit That May Come Later
Crummey notices are documents nobody thinks about until an estate tax audit, which can land years or decades after the gifts were made. For every contribution, the trustee’s permanent file should contain the signed or receipted copy of the letter, proof of delivery, a record of the lapse date, and a note confirming no beneficiary exercised the right — or, if one did, a copy of the written demand and proof of distribution.
The limitations period on gift tax matters only if a return was filed. For gifts properly disclosed on a timely Form 709, the IRS generally has three years to examine them. If no return was filed — because the grantor believed the annual exclusion eliminated the filing requirement — there is no limitations period, and the gift stays open to examination indefinitely. For that reason many estate planners file Form 709 every year a Crummey trust receives contributions, even when every gift sits within the $19,000 exclusion. Filing starts the clock.
Married couples who split gifts have a separate Form 709 trap. Both spouses must consent to split, and both must file Form 709 for the year, even if neither spouse’s individual gifts exceeded the exclusion.4Internal Revenue Service. Instructions for Form 709 (2025) The Crummey letter should reflect the combined contribution and name both donors, so the beneficiary sees the full amount available to withdraw. Missing a 709, or filing only one spouse’s return, can undo the split and strand half the gift outside the exclusion.
Trustees who let documentation slide sometimes try to reconstruct Crummey letters after the fact. Don’t. Backdated notices are affirmatively fraudulent and destroy credibility with an examiner far more thoroughly than a simple gap in the records. If a year’s notice was missed, the honest path is to treat that contribution as a future interest, report it on Form 709, and apply it against the lifetime exemption.
What a Good Letter Does Not Fix
A technically perfect Crummey letter secures the gift tax annual exclusion. It does not, by itself, resolve several related problems that trip up Crummey trusts.
When a beneficiary lets a withdrawal right lapse, the lapse is treated as a release of a general power of appointment — effectively a deemed gift from the beneficiary to the trust’s other beneficiaries. IRC Section 2514(e) provides a safe harbor only to the extent the lapsing amount exceeds the greater of $5,000 or 5% of the trust’s assets.5Office of the Law Revision Counsel. 26 USC 2514 – Powers of Appointment A $19,000 lapse in a small or new trust can leave a sizable amount outside the safe harbor. Well-drafted trusts use a “hanging power” to spread the lapse over multiple years, but the hanging amount makes the beneficiary a partial owner of the trust under IRC Section 678, which means they owe income tax on a proportionate share of trust earnings they never receive.6Office of the Law Revision Counsel. 26 USC 678 – Person Other Than Grantor Treated as Substantial Owner
If the trust benefits grandchildren or other skip persons, the generation-skipping transfer tax runs on a separate track. A Crummey power that qualifies a gift for the gift tax annual exclusion does not automatically qualify it for the GST annual exclusion. Under IRC Section 2642(c), a transfer gets a zero GST inclusion ratio only if the trust benefits a single skip person, no distributions can go to anyone else during that person’s life, and the assets would be in the beneficiary’s estate at death.7Office of the Law Revision Counsel. 26 USC 2642 – Inclusion Ratio A typical multi-beneficiary family trust fails those requirements, so contributions still consume the grantor’s GST exemption even when the Crummey letter does its job on the gift tax side.8Congress.gov. The Generation-Skipping Transfer Tax (GSTT)
And when grantors stretch by handing Crummey powers to people with no real stake in the trust — contingent remainder beneficiaries added only to generate extra annual exclusions — the IRS has signaled it will challenge those “naked” powers under substance-over-form principles, as it did in Technical Advice Memorandum 9628004. Giving withdrawal rights to beneficiaries with a genuine economic interest in the trust is the safer design, regardless of how carefully the letter is drafted.
None of these issues changes what has to be in the letter itself. They do mean the letter is one piece of a larger structure, and the structure needs its own review by the attorney who drafted the trust and the accountant who files the returns.
