Charitable Remainder Annuity Trust Listed Transaction Rules

From 9 July 2026, a specific charitable remainder annuity trust pattern is a listed transaction: property is contributed to a CRAT, the trust claims a stepped-up basis it is not entitled to, sells the asset largely tax-free, buys an annuity, and the beneficiary treats most of the payout as untaxed. Participants and advisers must disclose. Genuine philanthropy is unaffected.

For philanthropic US-connected families, the arrival of a charitable remainder annuity trust listed transaction designation is unsettling for the wrong reason. Most people who hear the phrase assume the CRAT itself is under attack. It is not. Section 664 trusts remain a wholly legitimate, statutorily blessed way to convert a concentrated low-basis position into a lifetime income stream while committing a meaningful remainder to charity. What the Treasury has done is far narrower, and far more surgical: it has identified one engineered fact pattern, given it a name, and attached mandatory disclosure to everyone who touches it.

The distinction matters because the penalty regime for listed transactions is severe and largely indifferent to intent. At Jungle Tax we advise US-UK families whose charitable structures were built years ago, often by advisers on one side of the Atlantic only, and who now need a defensible file rather than a comfortable assumption. This guide sets out what the regulations actually reach, how a genuinely charitable family conducts a review, what the substantially-similar test captures, and where the UK side of a dual-resident family creates its own reporting exposure.

What the final regulations actually target

The flagged arrangement is not a CRAT in isolation. It is a sequence of four steps that only produces its promised result if every step holds. Strip out any one of them and the transaction is either ordinary or simply ineffective.

Step one: contribution of appreciated property

The settlor contributes highly appreciated property to a charitable remainder annuity trust. Frequently this is farmland, development land, a closely held interest, or a concentrated equity position. Nothing is wrong at this stage; this is the classic and intended use of a CRAT.

Step two: the basis assertion

Here is the fault line. The promoters of the flagged structure assert that the trust takes a fair market value basis in the contributed property, as though the transfer were a transmission at death under section 1014. It is not. A lifetime gift to a charitable remainder trust is a carryover basis transaction under section 1015. The asserted step-up is the entire engine of the scheme, and it is unsupported.

Step three: the near tax-free sale

Armed with the inflated basis, the trust sells the property and reports little or no capital gain. Because a properly administered CRAT is itself exempt from income tax on its own gains, the mischief is not in the trust-level exemption; it is in the character and amount of gain that lands in the four-tier accounting system and therefore in the beneficiary's hands.

Step four: the annuity wrapper

The trust applies the proceeds to purchase a single premium immediate annuity. The annuity payments flow to the beneficiary, who then reports only the modest interest element under the general annuity rules, treating the balance as a tax-free return of investment. The suppressed gain from step three never surfaces. Millions of dollars of appreciation are, on the promoter's theory, simply extinguished.

Once you see the structure laid out this way, the reason for the listed-transaction treatment is obvious. This is not aggressive planning at the margin. It is a claimed basis that has no statutory foundation, dressed in the clothing of a respectable charitable vehicle.

Is my existing CRAT now a listed transaction?

Almost certainly not, if it was built and administered properly. Ask yourself three questions.

• What basis did the trust use when it sold the contributed asset? If the trust reported the settlor's carryover basis and recognised the full economic gain into the trust's tier-one and tier-two accounts, the defining element of the flagged pattern is absent.
• Did the trust buy an annuity with the sale proceeds? A CRAT that invests in a diversified portfolio and pays the annuity amount out of trust assets is structurally different from one that outsources the payment obligation to an insurance contract in order to re-characterise it.
• Is the charitable remainder economically real? Genuine structures satisfy the 10 per cent minimum remainder value test and the 5 per cent probability test with room to spare, and the named charity is a real institution with a real expectation of receiving something.

Where all three answers are clean, the trust is what it purports to be. Where any answer is unclear, the correct response is a documented file review, not silence. The reporting obligation attaches to participation in a transaction the same as or substantially similar to the identified one, and the taxpayer bears the burden of showing why the description does not fit.

Where does the substantially similar test bite?

This is the provision that causes the most anxiety, and rightly so. The substantially-similar standard is deliberately broad: it captures transactions expected to obtain the same or similar types of tax consequences and that are either factually similar or based on the same or a similar tax strategy. Cosmetic differences do not save an arrangement.

In practice, the following variations should be treated as inside the perimeter until an adviser concludes otherwise in writing:

• Use of a deferred annuity, a period-certain annuity, or a commercial annuity issued by a related or offshore carrier rather than a straightforward single premium immediate annuity.
• Interposing a partnership, LLC or holding company between the settlor and the trust so that the trust receives units rather than the underlying asset, while the same basis assertion is made at one remove.
• Using a charitable remainder unitrust rather than an annuity trust while replicating the basis step-up and annuity-wrapper mechanics.
• Splitting the arrangement across two or more trusts, or across two tax years, so that no single filing shows the whole picture.
• Contributing property subject to debt, or contributing an asset shortly before a pre-negotiated sale, in a way that relocates gain away from the settlor.

Conversely, structures that share only the CRAT wrapper and none of the basis or annuity mechanics are not caught merely because they are tax-efficient. Efficiency is not avoidance. The regulations reach a claimed tax result, not a vehicle.

Who has to disclose, and on what form?

Two separate populations acquire obligations, and they are not interchangeable.

Participants — the settlor, the trust itself, and in many cases the annuity beneficiary — file a reportable transaction disclosure statement with the return for each year of participation, and send a copy to the IRS Office of Tax Shelter Analysis. The IRS guidance on the disclosure form is set out at About Form 8886. A charitable remainder trust separately files its annual split-interest information return, which is where an examiner will first see the four-tier accounting that either supports or undermines the family's position.

Material advisers — the promoter, and potentially the accountant, attorney or valuer who provided material aid, assistance or advice above the applicable fee threshold — file a separate material adviser disclosure and must maintain and produce a list of advisees on request. The IRS description is at About Form 8918. Families are often surprised to learn that their own long-standing adviser may have a filing obligation that is independent of, and may precede, their own.

The background rules for split-interest trusts generally, including the four-tier ordering system, are summarised on the IRS charitable remainder trusts page. That ordering is the single most useful diagnostic in a review: if a trust has distributed large sums while reporting almost no tier-one or tier-two income, something needs explaining.

US and UK treatment compared

For a dual-resident or mixed-nationality family, the two systems do not merely differ in rate. They differ in whether the vehicle is recognised at all.

Issue	United States (IRS)	United Kingdom (HMRC)
Recognition of the CRAT	Statutory vehicle under section 664; trust is tax-exempt on its own income, with tax pushed out to the beneficiary under the four-tier system	No direct equivalent; typically analysed as an ordinary settlement, with trustee residence and beneficiary residence driving the outcome
Income tax deduction on funding	Charitable deduction for the present value of the remainder interest, subject to percentage-of-income limits and carryforward	No deduction for the remainder interest; UK relief generally requires an outright qualifying gift under Gift Aid or the gifts-of-assets rules
Charity qualification	Remainder must pass to a US-qualified organisation for deduction purposes	Relief generally requires a UK or qualifying EEA-equivalent charity; a US charity alone will usually not qualify
Beneficiary taxation of the annuity	Four-tier ordering: ordinary income, then capital gain, then tax-exempt income, then corpus	Payments to a UK resident beneficiary are assessed under UK trust and settlements rules, which do not mirror the tiers
Anti-avoidance disclosure	Reportable and listed transaction regime, with participant and material adviser filings	Disclosure of tax avoidance schemes regime, plus the general anti-abuse rule
Estate and inheritance treatment	Remainder to charity generally removes the asset from the taxable estate	Inheritance tax analysis depends on long-term residence status and whether the settlement is excluded property

The practical consequence is that a US-designed CRAT can be entirely compliant in Washington and still generate an unrelieved UK charge on a beneficiary who has become UK resident. We look at that mismatch routinely as part of cross-border tax planning for families with members on both sides.

Does HMRC have an equivalent listing regime?

Not identically, but the direction of travel is the same. The UK operates a disclosure of tax avoidance schemes regime with hallmarks that catch arrangements with a main benefit of tax advantage, alongside the general anti-abuse rule and the enablers penalties. HMRC's technical treatment of settlements is set out in its Trusts, Settlements and Estates Manual, and the disclosure framework is summarised in HMRC's guidance on disclosure of tax avoidance schemes.

The point for a US-UK family is not that HMRC will replicate the IRS designation. It is that an arrangement disclosed as a listed transaction in the United States is highly unlikely to be viewed sympathetically in the United Kingdom, and that a UK-resident settlor or beneficiary should assume the two revenue authorities will exchange the information. Our UK tax services team routinely reconciles a US filing position with what HMRC will accept on the same facts.

How should a philanthropic family run the review?

A defensible review is a documentary exercise, not a conversation. We would expect the file to contain the following.

• The trust instrument, checked against the section 664 requirements and any applicable sample form, including the annuity percentage, the payment frequency and the remainder provisions.
• The funding schedule, showing what was contributed, when, and the settlor's basis in each asset, with supporting acquisition records.
• The qualified appraisal supporting the value of the contributed property and the calculated remainder interest.
• The trust's own returns for every year of existence, with the four-tier accounting reconciled year on year rather than reconstructed.
• Investment records showing whether sale proceeds were invested in a portfolio or applied to purchase an annuity contract, and on what commercial terms.
• Beneficiary reporting, confirming that distributions were reported consistently with the trust's tier characterisation and not with a more favourable annuity analysis.
• Charity correspondence, evidencing that the named remainder organisation exists, is qualified, and has been notified of its interest.

Where the review is clean, that file is the answer to any future enquiry. Where the review identifies the flagged pattern, the family has decisions to make quickly, because disclosure obligations and the extended assessment period both turn on filing rather than on discovery. Families in that position should also review their broader offshore disclosure posture; our IRS streamlined filing specialists frequently find that a problematic trust sits alongside unreported foreign accounts or unfiled information returns.

What are the consequences of failing to disclose?

Non-disclosure of a listed transaction carries a dedicated penalty regime that is separate from, and additive to, any underpayment of tax. Key features to understand:

• The penalty for failure to disclose a listed transaction is calculated by reference to the tax benefit claimed, subject to statutory maximums that differ for individuals and entities.
• The reasonable cause defence is significantly narrowed for listed transactions compared with ordinary accuracy penalties.
• The limitation period for assessment does not begin to run in the normal way where a required listed transaction disclosure has not been furnished, which can leave old years open indefinitely.
• An accuracy-related penalty applies to any understatement attributable to a reportable transaction, at a higher rate where the transaction was not disclosed.
• Material advisers face their own penalties for failure to file and for failure to maintain or furnish the advisee list.

The asymmetry is deliberate. Disclosure is not an admission that the transaction is abusive; it is a protective filing that preserves defences. For a family with an ambiguous fact pattern, protective disclosure with a clear explanatory statement is very often the right answer, and it should be prepared by someone who understands both the technical position and how it will read to an examiner.

What this means for genuine philanthropy

Nothing in this development should discourage a family from using a charitable remainder trust for its intended purpose. The economics remain compelling: a low-basis concentrated position can be diversified inside an exempt trust, an income stream secured for a spouse or child, a current charitable deduction claimed, and the asset removed from the taxable estate. What has changed is the standard of documentation required to demonstrate that this is what you actually did.

For cross-border families there is a further planning point. Because the UK does not mirror the US treatment, the identity and residence of the annuity beneficiary is now a first-order design question rather than an administrative afterthought. A US-resident beneficiary and a UK-resident beneficiary receiving identical payments from the same trust can face materially different effective rates, and treaty relief does not always align the two. Structuring decisions of this kind sit squarely within high net worth advisory work and should be modelled before, not after, the trust is funded.
