The December Letter That Keeps a Family Trust Gift-Tax Free
A single page mailed each December decides whether a trust contribution qualifies for the annual gift-tax exclusion. Miss it, and the IRS is under no obligation to tell you.

Families funding irrevocable trusts must send beneficiaries a one-page "Crummey letter" each year granting a temporary right to withdraw the new contribution, and skipping it can cost thousands in annual gift-tax exclusions with no warning from the IRS, according to 24/7 Wall St.
Every December, in households that would never describe themselves as tax-planning operations, someone prints a short letter, signs it, and drops it in the mail. It is rarely more than a page. It usually goes to a child, a grandchild, or a family member who has no idea what to do with it. And it is frequently the only thing standing between a trust contribution that qualifies for the annual gift-tax exclusion and one that does not.
The document is known as a Crummey letter, or more formally a Crummey withdrawal notice. Its function is narrow and its consequences are not. As 24/7 Wall St reports, most families funding irrevocable trusts lose thousands in gift-tax exclusions every year over a single missing piece of paperwork — and the IRS is under no obligation to tell them they have done it.
Why a gift into a trust is not automatically an excluded gift
The annual gift-tax exclusion lets a person give a certain amount to any number of individual recipients each year without eating into their lifetime gift and estate tax allowance and without triggering a gift-tax return requirement for that transfer. The IRS sets the figure and adjusts it periodically for inflation, publishing the current amount each year.
The catch is a phrase buried in the rule: the exclusion applies only to gifts of a present interest. That means the recipient must be able to get their hands on the money now, not at some future date on someone else's terms.
An irrevocable trust is designed to do precisely the opposite. The whole point of putting assets inside one — whether for estate-tax reasons, creditor protection, or the simple wish that an 18-year-old not receive a lump sum — is that the beneficiary cannot touch the money yet. That is a future interest. Left alone, a contribution into such a trust is a taxable gift that consumes lifetime exemption, even if the amount would have sailed under the annual exclusion had it been handed over in cash.
The workaround that a taxpayer named Crummey won in court
The solution that estate planners have relied on for decades is deceptively simple: give the beneficiary a genuine, temporary right to withdraw the new contribution. For a limited window — commonly measured in days or weeks and specified in the trust document — the beneficiary can demand the money. Once the window closes without a demand, the funds stay in the trust and are governed by its long-term terms.
Because the beneficiary had a real, immediate power to take the money, the contribution counts as a present interest, and the annual exclusion applies. The technique carries the name of the taxpayer whose court victory established that the arrangement works.
The right, however, has to be real. And a right the beneficiary was never told about is difficult to characterize as real. That is the job of the letter: it notifies each holder of a withdrawal power that a contribution has been made, states the amount available to them, and states the deadline by which they must act if they want it.
What the notice has to do to hold up
There is no government-issued Crummey form to fill in. The notice is drafted by the trustee or the family's attorney, and its adequacy is judged on substance. In practice, that means several things matter more than the prose.
- Every power holder gets one. If a trust gives withdrawal rights to four beneficiaries, four notices go out. A minor's notice goes to their legal guardian — and, awkwardly for many families, that guardian is often the same parent making the gift.
- The timing tracks the contribution. The notice should follow the funding, not float free of it. A trust funded in December generates December letters; a trust funded in three tranches generates three rounds.
- The window is honored. If a beneficiary exercises the withdrawal right, the trustee has to pay. A power that would be quietly refused is not a power.
- The paper is kept. Signed acknowledgments, mailing records, and copies in the trust file are what an examiner asks for years later — often after the person who made the gifts has died and can no longer explain the pattern.
That last point is where the real exposure sits. The failure almost never announces itself. A family can miss notices for a decade, receive no correspondence, and believe the plan is working. The reckoning tends to arrive during an estate-tax examination, when contributions the family treated as excluded are recharacterized as taxable gifts that should have been reported — with the lifetime exemption reduced accordingly and, potentially, penalties and interest attached to returns that were never filed.
Where the money actually leaks
The notice is drafted by the trustee or the family's attorney, and its adequacy is judged on substance.
The structures most likely to be affected are the ordinary ones. Irrevocable life insurance trusts are the classic case: the family gifts cash into the trust each year, the trustee pays the policy premium, and the death benefit ultimately sits outside the taxable estate. Those annual premium gifts are exactly the transfers that need Crummey notices, and they recur for as long as the policy does — which is to say, for decades.
Multi-generational trusts funded with annual gifts have the same profile, as do trusts holding marketable securities, where a portfolio compounding alongside a broad market that has continued to grind higher — the S&P 500 tracker SPY closed at $765.72 on Friday, August 21, up 0.41% on the day — quietly raises the stakes on the estate-tax math the trust was built to manage.
The loss is not theoretical. Each contribution that fails the present-interest test is exclusion the family had a legal right to and did not claim. Repeated annually across several beneficiaries, that is the multi-thousand-dollar leak described in the report — money that does not come back.
What families should check before year-end
December is when most of this gets done, because it is when annual gifting is finalized before the calendar resets the exclusion. A few questions are worth putting to whoever administers the trust while there is still time to fix the current year.
- Who exactly holds withdrawal powers under the trust document, and has each of them been sent a notice for this year's contribution?
- How long is the withdrawal window, and does the mailing date leave enough runway before year-end?
- Are signed acknowledgments being returned and filed, or are letters simply being sent into the void?
- For minor beneficiaries, is the notice going to the correct guardian, and is that documented?
- Where is the historical file — and does it cover every year the trust has been funded?
None of this requires new legislation, a new product, or a change in strategy. It requires a page, a date, and a filing cabinet. The families that treat the Crummey letter as an annual administrative ritual keep the exclusion. The ones that treat it as optional find out it was not, usually at the worst possible moment, and usually from an examiner rather than a warning notice.
Frequently asked questions
What is a Crummey letter?
A Crummey letter, or Crummey withdrawal notice, is a short written notice sent by a trustee to the beneficiaries of an irrevocable trust telling them that a contribution has been made and that they have a limited window in which they may withdraw their share of it. The notice is what makes the gift qualify for the annual gift-tax exclusion.
Why does a gift into an irrevocable trust need a special notice?
The annual gift-tax exclusion applies only to gifts of a present interest — money the recipient can access immediately. An irrevocable trust normally locks assets away, creating a future interest that does not qualify. Giving beneficiaries a temporary right to withdraw the contribution, and telling them about it, restores the present-interest character.
What happens if the letters are never sent?
Contributions may be recharacterized as taxable gifts rather than excluded ones. That consumes lifetime gift and estate tax exemption, can create unfiled gift-tax return obligations, and may expose the family to penalties and interest. The problem typically surfaces during an estate-tax examination, often years later and after the donor has died.
Does the IRS notify families that a notice was missed?
No. The report notes the IRS is under no obligation to warn families that the paperwork is missing. Nothing in the filing process automatically flags an absent Crummey notice, which is why the failure can continue undetected for many years before an examination brings it to light.
Which trusts most commonly require Crummey notices?
Irrevocable life insurance trusts are the classic example, because the family gifts cash annually to cover premiums and each of those gifts needs to qualify for the exclusion. Multi-generational family trusts funded through recurring annual gifts, and trusts holding marketable securities, fall into the same category.
What should be kept on file to prove the notices were given?
Copies of each letter, signed acknowledgments returned by beneficiaries, mailing or delivery records, and documentation of who received notices on behalf of minor beneficiaries. Examiners generally ask for the full history, so the file should cover every year in which the trust received a contribution.
