Family Philanthropy: Foundations, DAFs and Cross-Border Giving

Charitable capital is a separate estate, not a wing of the family's

When a family office first raises the subject of philanthropy, the conversation usually starts with accounting and structure: who holds the asset, what deduction the donor gets, what happens to control once the transfer is done. Charitable capital behaves like a separate asset class, with its own tax regime, its own governance and its own liquidity constraints.

UBS's Global Family Office Report 2025 finds that 41% of family offices pursue their sustainability and impact agenda through philanthropy — more often than through the operating business (30%) or the investment portfolio (26%). And 44%, when planning succession, expect the next generation to be involved in charitable projects: the second most common answer after board seats. For a family office this is one of the load-bearing joints of the work.

What follows is how that joint is built technically: which instruments are available in the main jurisdictions, why cross-border giving runs into the same wall almost everywhere, and what separates a working programme from an expensive shop window.

One example runs through the whole article. A founder holds 70% of an operating company and a block of listed shares in an unrelated group; the family wants a permanent institution, a real role for two adult children, and a deduction against this year's income. Every element lands on a different gate. The operating stake cannot go into a private non-operating foundation in any size the family would recognise, because §4943 caps the foundation and its disqualified persons at 20% of the voting stock of one business. The listed block can go in at market value — but only up to 10% of that company's outstanding stock, and only if the gift completes before the family's right to any sale proceeds has ripened. The children may sit on the board and may be paid, but only for personal services that are reasonable and necessary; leasing the family's building to the foundation is barred whatever the rent. And a grant to the school the family funds abroad is not a qualifying distribution merely because the school is a charity where it sits.

Three features of the system drive everything below. First, control and benefit are policed separately: a family can keep a great deal of control and still lose the relief because benefit leaked back, and can keep almost none — a donor-advised fund — and be entirely safe. Second, every limit is a statutory number attached to a specific vehicle rather than a general principle, so a cap that makes one structure unusable may simply not exist in the next one. Third, recognition is asymmetric and one-directional: the recipient's status at home settles nothing, the grantor's own system settles everything, and it settles the question differently for income tax, gift tax and estate tax.

Why a family does it

There are four reasons, and altruism is only one of them.

Tax. A gift converts part of taxable income, or of the estate, into a deduction. The difference between instruments is measured in tens of percentage points, so the choice of structure is a thoroughly technical question.

Succession. A charitable foundation is a low-risk training ground for heirs. It has a budget, a board, reporting and decisions with consequences, but no risk of wrecking the operating business. Many families use it exactly that way, folding it into the wider logic of succession planning.

Concentration. A founder whose wealth sits almost entirely in a single holding cannot exit the position without a capital gains charge. Transferring a stake into a charitable structure is one of the few lawful ways to unwind it.

Reputation. A public foundation is a statement of values, and for that reason it carries risk as well as benefit.

United States: private foundation versus DAF

The American toolkit is the most developed and the most heavily regulated.

A private foundation gives full control: the family appoints the board, sets the strategy, hires the staff. The price of that control is the Chapter 42 regime, whose quantitative terms are all set by statute.

The numbers are half the regime; the prohibitions are the other half. Self-dealing (§4941) blocks virtually any transaction between the foundation and a disqualified person: a sale, a lease, a loan, the provision of services, a transfer of property for the benefit of such a person. The prohibition operates objectively — whether the deal is advantageous to the foundation is irrelevant. For a family planning to move a controlling block of the operating company into a private foundation, the excess business holdings cap is a stop signal.

The donor's deduction is uneven too:

The exception to that last row is qualified appreciated stock — publicly traded securities, which may be given to a private foundation at market value. A stake in the family business, or land, may not. An art collection is a case of its own: paired with public access and the related-use test it supports an FMV deduction, and that is what the private museum inside a charitable foundation is built on.

Timing the gift of a company

The founder's real problem is usually a single concentrated block, and what the deduction is worth turns less on what is given than on when. Two limits and one doctrine settle it.

The qualified appreciated stock exception is itself capped. Under §170(e)(5)(C) stock ceases to be qualified appreciated stock to the extent the contribution, added to all of the donor's earlier contributions of that company's stock, exceeds 10% in value of all the outstanding stock of the corporation. Above that line the deduction falls back to basis even for a listed security. Anything not quoted brings its own paperwork: a qualified appraisal is required once the claimed value of the contributed property exceeds US$5,000, and the appraisal itself must be attached to the return once the claimed value exceeds US$500,000 (§170(f)(11)).

Nine days too late. The doctrine that catches families is the anticipatory assignment of income: give the shares and the appreciation travels with them; give what has already become a right to proceeds and the tax stays behind. In Ferguson v. Commissioner (United States Court of Appeals for the Ninth Circuit, 7 April 1999, No. 98-70095, 174 F.3d 997) shareholders of a company under a tender offer transferred stock to charitable donees on 9 September 1988. The court held their right to the proceeds had already ripened on 31 August, when more than 50% of the outstanding shares had been tendered, and that "once a right to receive income has 'ripened' for tax purposes, the taxpayer who earned or otherwise created that right will be taxed on any gain realized from it, notwithstanding the fact that the taxpayer has transferred the right before actually receiving the income." The charities got the shares; the donors kept the gain. The working rule is therefore about sequence, not about the tax year: the transfer must complete while the sale is still genuinely contingent, not once it has become a matter of mechanics — which puts the charitable step inside the business succession timetable rather than in the year-end tax review.

The donor-advised fund sits at the opposite pole. The donor transfers funds to a sponsor (usually a public charity), takes the deduction immediately and at the generous limits, but from then on merely recommends grants. Formally there is no control; in practice sponsors follow the recommendations. There is no statutory payout requirement for DAFs — and that is the critics' main argument: the deduction is taken today, while the money may not reach beneficiaries for years. The scale makes the argument concrete. According to the DAF Research Collaborative, DAFs held USD 327.9 billion across 3.59 million accounts at the close of fiscal 2024, grants came to USD 64.6 billion, and the aggregate payout rate was 25.2%. Reform proposals — the ACE Act and its successors — would impose hard distribution deadlines; none has been enacted.

And separately: the limits in the table are ceilings. From 2026 a floor and a cap have been added to them:

2026 rules (US). From 1 January 2026 the OBBBA floors and caps apply: the deduction for itemizers works only above a floor of 0.5% of AGI, the value of the deduction in the top bracket is capped at 35 cents on the dollar, and corporations face a floor of 1% of taxable income. A new above-the-line deduction of $1,000/$2,000 is available to non-itemizers. The practical answer to the floor is bunching: several annual giving budgets in a single DAF contribution. The full arithmetic is set out in the breakdown of the charitable deduction mechanics.

Beyond the binary: the vehicles the two-way choice leaves out

"Foundation or DAF" is a false pair. US law offers at least five charitable vehicles, and the constraint that makes one of them unusable is very often absent from the next.

A private operating foundation (§4942(j)(3)) runs its own programme instead of funding other people's — a museum, an archive, a research institute, a clinic. It must make qualifying distributions equal to substantially all of the lesser of its adjusted net income or its minimum investment return, spent directly on the active conduct of its exempt activities, and satisfy one of three further tests: an assets test (substantially more than half its assets devoted directly to those activities or to functionally related businesses), an endowment test (qualifying distributions of at least two-thirds of its minimum investment return), or a support test (broad support, no single exempt-organisation source above 25%, investment income no more than 50% of total support). The payoff sits on the donor's side of the transaction: contributions take the public-charity ceilings rather than the 30/20% private-foundation ones, because §170(b)(1)(A)(vii) routes them through §170(b)(1)(F)(i).

The same subparagraph offers a second escape that costs nothing structurally. Under §170(b)(1)(F)(ii) an ordinary private foundation earns the public-charity ceilings for a given year's contributions if it makes qualifying distributions equal to 100% of those contributions not later than the 15th day of the third month after the close of the taxable year in which they were received — the "conduit" or pass-through foundation, built for a single large gift the family wants deployed quickly rather than endowed.

A supporting organisation (§509(a)(3)) is a public charity by relationship: it exists to support one or more identified public charities and, in exchange, escapes the private-foundation excise regime. The exchange is not total. §4943(f) applies the excess business holdings cap to a Type III supporting organisation that is not functionally integrated, and to a supervised or controlled organisation that accepts gifts from a person who controls the supported charity. A family that moves an operating stake into a supporting organisation has not escaped §4943, only relabelled it. §4943(e) does the same job for donor advised funds, which are read as private foundations for excess business holdings, with "disqualified person" meaning the donor, the person with advisory privileges, their family and their 35-percent controlled entities.

A charitable remainder trust (§664) answers a different question: the family wants income now and the charity to take what is left. A CRAT pays a sum certain, a CRUT a fixed percentage of assets revalued annually; either way the payout must be not less than 5% and not more than 50%, the term is a life, lives, or a fixed term of no more than 20 years, and the actuarial value of the charitable remainder — computed with the §7520 rate — must be at least 10% of the value placed in the trust (§664(d)(1)(A) and (D); §664(d)(2)(A) and (D)). A charitable lead trust inverts the order of the two interests. The deduction arithmetic for both, and how each behaves with appreciated stock, is worked through in the charitable deduction mechanics; what matters here is that a split-interest trust is the only one of these vehicles that pays anything back to the family.

Read the table as a router, not a ranking. Start from the asset and the answer usually names itself: a controlling operating stake points away from all four charity vehicles and towards a sale first; a listed block points at a DAF or a CRT; a working museum or archive points at an operating foundation; a family that wants an institution but not the staff to run it points at a supporting organisation attached to a charity that already has them.

United Kingdom: Gift Aid and the bequest threshold

The British mechanics work the other way round: the relief flows to the recipient as well as the donor. Under Gift Aid the charity reclaims 25 pence from HMRC on every pound given, while a higher-rate donor recovers the difference between their rate and the basic rate through self-assessment. The arithmetic is transparent: on a gift of £100 the charity receives £125 and the donor gets £25 back.

Gift Aid only reaches cash. Assets travel a separate route: an individual who disposes of the whole of the beneficial interest in a qualifying investment — broadly listed shares and securities, units in authorised funds and qualifying interests in land — to a charity "otherwise than by way of a bargain made at arm's length" may claim relief "by deducting the relievable amount in calculating the individual's net income for the tax year in which the disposal is made" (ITA 2007 s.431(1)–(2), with the catalogue of qualifying investments in s.432). The capital gains side is handled separately and automatically: under TCGA 1992 s.257(2)(a) the disposal and acquisition are treated as made "for such consideration as to secure that neither a gain nor a loss accrues on the disposal". The two together are the British answer to a concentrated holding — income relief at value, no charge on the gain — and the reason a UK donor sitting on appreciated listed stock should never sell first and give the cash.

Registration with the Charity Commission is compulsory once income reaches £5 000 a year. A CIO — charitable incorporated organisation — registers regardless of income: a corporate form with its own legal personality and limited liability for trustees but, unlike a charitable company, with no parallel registration at Companies House.

The most interesting piece is the bequest relief. Gifts by will fall outside IHT entirely, and where at least 10% of the net estate passes to charity the rate on the remainder drops from 40% to 36% (for deaths on or after 6 April 2012). The threshold produces a characteristic effect: near the 10% mark, increasing the charitable share barely reduces what the heirs receive — the lower rate applied across the whole taxable estate offsets the larger gift. Estate planning in a UK context is incomplete without that calculation.

The Continent: the Stiftung as a form

In civil law the role of the private foundation is played by the Stiftung. A classic Swiss foundation is created by notarial deed or by will, entered in the commercial register and placed under supervision: federal (ESA) for bodies of national or international significance, cantonal for local ones. The ESA expects at least CHF 50 000 of liquid assets on formation, an annual report within six months of the year end and, as a rule, an auditor.

The Liechtenstein model is more flexible on the private side, but for public-benefit (gemeinnützige) foundations the regime is similar: mandatory entry in the register, mandatory STIFA supervision, mandatory audit with carve-outs for smaller structures. A private family Stiftung, by contrast, is not subject to supervision at all — and that fork is the central decision when structuring a Liechtenstein foundation.

The Swiss donor's deduction runs to 20% of net income on gifts of CHF 100 or more (art. 33a DBG).

The cross-border trap

Almost everywhere, the deduction is tied to the recipient's residence.

The Swiss rule expressly requires the legal entity to have its Sitz in Switzerland. The United States is stricter: §170(c)(2) requires the organisation to be created or organized in the United States. Exceptions are granted by the treaties with Canada, Mexico and Israel — and they work only against income sourced in the country concerned. After Brexit the United Kingdom narrowed relief to UK charities: the transitional period for EU and EEA bodies ended on 1 April 2024 (for income tax and CGT, from the 2024/25 year).

Within the EU, the Court of Justice's rulings in Stauffer and Persche obliged member states to extend relief to comparable organisations established in other member states. But comparability has to be proved by the donor, and the administrative costs often exceed the value of the gift.

Hence three workarounds.

The diagram below shows whom the money passes through in each of them and where the receipt for the deduction arises.

• Transnational Giving Europe: the donor gives to a partner foundation at home, receives a domestic receipt, and the partner forwards the funds to the foreign recipient.
• "Friends of" structures: a US 501(c)(3) raising money for a foreign project — on condition that it genuinely controls the funds rather than serving as a conduit.
• Dual-qualified structures for those taxed in two jurisdictions: a UK charitable company treated by the IRS as a disregarded entity of a US sponsor, so that a single contribution produces both Gift Aid and a US deduction.

Death and lifetime gifts are not judged alike

The residence rule that blocks a lifetime deduction belongs to the income tax, and it does not carry across to the transfer taxes. The asymmetry is worth real money and is routinely missed.

§170(c)(2)(A) requires the recipient to be "created or organized in the United States or in any possession thereof, or under the law of the United States, any State, the District of Columbia, or any possession of the United States." The estate tax charitable deduction contains no such words: §2055(a)(2) allows the deduction for a transfer "to or for the use of any corporation organized and operated exclusively for religious, charitable, scientific, literary, or educational purposes" and never asks where it was organised. The gift tax deduction in §2522(a)(2) is drafted the same way. So a US citizen or resident who gives a foreign charity a million dollars in life gets no income tax deduction at all and a full gift tax deduction; the identical sum left to the identical charity by will comes straight out of the taxable estate.

The mirror image catches the family on the other side of the border. For a decedent who is neither a citizen nor a resident, §2106(a)(2)(A)(ii) allows the deduction only for a transfer to a domestic corporation, and §2522(b)(2) imposes the same domestic requirement on lifetime gifts by a nonresident non-citizen. A non-US family holding US-situs assets therefore has the opposite problem from the American donor: the charity has to be American, or the relief is simply absent. That belongs in the planning for anyone already inside the US estate tax perimeter, and it changes the ordinary lifetime gifting sequence rather than sitting beside it.

Governance: where philanthropy stops being a chequebook

A foundation can be set up in a month. It becomes a programme once three documents exist.

The mission statement is a working constraint: it determines which applications are considered at all. Without it the foundation turns into a reactive cash desk handing out money to acquaintances. It belongs in the same circuit as the family constitution.

The investment policy for charitable capital is a document separate from the family portfolio. The key question is whether return may be sacrificed for mission. In the United States the answer is given in Notice 2015-62: foundation managers may take the relationship between an investment and the exempt purposes into account when assessing whether it is prudent — meaning that mission-related investing does not by itself constitute a jeopardizing investment under §4944.

And the grant policy: the procedure that separates grant-making from impulse — selection criteria, timelines, evaluation of results.

The same place marks the boundary between three modes of operation.

• A grant is non-returnable.
• Impact investing is returnable and demands a financial return.
• Venture philanthropy sits in between: patient money, deep engagement in the recipient's management, metrics.

The skills required differ, and trying to run all three with one team usually ends with the foundation doing all of them badly.

Donor intent and the shape of the gift

A completed charitable gift changes ownership. Once the transfer is legally complete, the asset belongs to the charity, foundation or fund, and the donor holds no property in it. What survives the transfer is not control but intent — and intent binds only to the extent it was written into the gift.

An unrestricted gift hands the recipient full discretion over use, timing and eligibility, within the recipient's own charitable objects. A restricted gift ties the money to a stated purpose, programme, place, class of beneficiary or time horizon — an endowment that must be held while only its income is spent is the classic form. The restriction is a legal condition on the recipient, enforceable as such; it is not a leash back to the donor.

Who enforces it matters. In common-law systems the state Attorney General — in England, the Charity Commission alongside the Attorney General — holds the primary power to enforce charitable purposes under the parens patriae doctrine. A donor, once the gift is complete, generally has no standing to sue over misuse unless standing was reserved: by an express contract or standing clause, by a reversion (the gift returns to the donor or a named successor charity on breach), or by statute. That is why donors of large restricted gifts increasingly negotiate enforcement rights into the gift agreement rather than relying on goodwill.

The sharpest version of the distinction lives inside the donor-advised fund. After a DAF contribution the sponsoring charity owns the money outright; the donor keeps only advisory privileges — the right to recommend, not to direct. A recommendation the sponsor is legally free to decline is an advisory preference, not a legal obligation, however reliably sponsors follow it in practice. The same line runs through a family foundation: a founder who sits on the board exercises a fiduciary duty to the foundation's purpose, not a personal power over its assets.

The grant, end to end

A grant is not a payment; it is a controlled transfer with conditions that outlive the cheque. The cycle is the same whether the grantor is a US private foundation, a Swiss Stiftung or a DAF sponsor, even though the statutory hooks differ.

Eligibility screen. The mission statement decides which applicants are considered at all; the grant policy sets objective criteria. This is where the grantor confirms the applicant's status and that a grant would fall within the grantor's own charitable objects.

Due diligence on the recipient. The grantor verifies the recipient's legal form and charitable or tax status, its governance and financial health, and — critically — whether that status lets the grant count as a qualifying distribution without extra compliance. A grant to a domestic public charity is clean; a grant to an individual, a foreign body or a non-charity is not, and triggers the machinery below.

Grant agreement. The document that turns intent into obligation. It states the restricted purpose, the disbursement schedule (often tranches tied to milestones rather than a lump sum), permitted and prohibited uses, reporting obligations, the treatment of unspent funds, and — the load-bearing clause — the recipient's promise to repay any amount not used for the grant's purpose.

Disbursement and monitoring. Money moves against conditions: a first tranche on signature, later tranches on satisfactory reports or milestone evidence. Conditions give the grantor leverage that a completed lump-sum gift does not.

Reporting and close-out. The recipient accounts for how the funds were spent; the grantor evaluates against the stated outcomes and closes the grant — or acts on a diversion.

For US grantors two statutory regimes turn this from good practice into a compliance requirement. When a private foundation grants to anything other than a recognised public charity — a foreign organisation, another private foundation, an individual for travel or study — it must exercise expenditure responsibility under §4945, or the grant becomes a taxable expenditure. A DAF faces a parallel rule: a distribution to an individual, or to a non-charity without expenditure responsibility, is a taxable distribution under §4966, taxed at 20% on the sponsoring organisation and 5% on the fund manager.

The controls scale with how far the recipient sits from that safe harbour. Set side by side, the three recipient types demand very different paper.

The lesson of the table is that the recipient's own label never settles the treatment: the grantor's compliance path does.

Recognising the recipient across borders

The single most common mistake in cross-border giving is to treat "it's a charity" as the answer. A deduction, or a qualifying distribution, depends on the recipient's specific status in the grantor's own tax system and on the grantor following the right compliance path — not on a charity label the recipient carries at home.

The cross-border trap above showed why: relief is tied to the recipient's residence. When a US private foundation wants to fund a foreign body that has no IRS determination letter, it has two lawful routes rather than a shortcut. It can obtain an equivalency determination — a good-faith, written opinion from a qualified tax practitioner (attorney, CPA or enrolled agent) that the foreign grantee is the equivalent of a US public charity, prepared under Rev. Proc. 2017-53 and generally reliable for the two tax years following the opinion. Or it can exercise expenditure responsibility on the foreign grant. Either route makes the grant a qualifying distribution rather than a taxable expenditure; neither is optional simply because the recipient is "a charity in its own country."

For individual donors the residence rule is starker still, and the workarounds — Transnational Giving Europe, a genuinely controlling "friends of" charity, dual-qualified structures — exist precisely because a foreign charity's home-country status does not, by itself, produce a deduction back home.

Who may benefit: the charitable class and the personal-nexus bar

Before any of the machinery above engages, one question decides whether the structure is charitable at all: who is permitted to benefit. Families get this wrong in a predictable direction — they define the beneficiaries by their connection to the family.

In England and Wales the gate is statutory. A charitable purpose must fall within one of the thirteen descriptions in section 3(1)(a) to (m) of the Charities Act 2011 — from the prevention or relief of poverty through education, religion, health, citizenship, the arts, amateur sport, human rights, the environment, relief of those in need, animal welfare and the efficiency of the armed forces, to the sweeping-up head in paragraph (m) — and be for the public benefit (s.2(1)). Section 4(2) removes the old shortcut in terms: "In determining whether the public benefit requirement is satisfied in relation to any purpose falling within section 3(1), it is not to be presumed that a purpose of a particular description is for the public benefit."

A section of the public cannot be defined by who your people are. In Oppenheim v Tobacco Securities Trust Co Ltd (House of Lords, [1951] AC 297) a trust to educate the children of employees and former employees of a company and its subsidiaries failed as a charity even though the class ran to more than a hundred thousand people, because the beneficiaries were tied to one employer rather than to the community. The Upper Tribunal restated the point in The Independent Schools Council v The Charity Commission for England and Wales (Upper Tribunal, Tax and Chancery Chamber, 2011, [2011] UKUT 421 (TCC), refs TCC-JR/03/2010 and FTC/99/2010), quoting Lord Simonds — "it is a clearly established principle of the law of charity that a trust is not charitable unless it is directed to the public benefit" — and treating the employment nexus as precisely what made that trust private rather than public. The one way round it is narrow and, in the tribunal's own word, anomalous: trusts for the relief of poverty. The regulator states the rule flatly in its public benefit guidance (PB1, published 16 September 2013, last updated 20 August 2026): beneficiaries generally may not be defined by "their family relationship", by "their employment by an employer" or by "their membership of an unincorporated association", and "a charity must not have a purpose which is for the benefit of named individuals, whether or not they are poor."

Same risk, a different technique. US law runs no personal-nexus test on the class; it reaches the same destination through the requirement that assistance go to a charitable class and through the private-benefit doctrine. IRS Publication 3833 (Rev. 12-2014) puts it as a size-and-definiteness test: a charitable class "must be large enough or sufficiently indefinite that the community as a whole, rather than a pre-selected group of people, benefits when a charity provides assistance", an organisation "cannot target and limit its assistance to specific individuals", and "donors cannot earmark contributions to a charitable organization for a particular individual or family." The practical result is identical on both sides of the Atlantic. A hardship fund for the founder's relatives is not a charity anywhere. A hardship fund open to everyone in the town where the family's plant closed can be one everywhere — and the family may still choose the town.

Related parties and private benefit

Charitable capital is tax-favoured on one condition: the benefit flows to the public purpose, not back to the family. Every regime polices that boundary, and a grant is the most common place it is crossed.

In the US, self-dealing under §4941 bars almost any transaction between a private foundation and a disqualified person — substantial contributors, foundation managers, and their family and controlled entities — regardless of whether the deal is fair or even favourable to the foundation. A sale, a lease, a loan, paying a family member's company for services: all are penalised objectively. Beyond self-dealing, the doctrines of private inurement and private benefit can cost a charity its exempt status where its resources enrich insiders or serve private interests more than incidentally. Inside a DAF, §4967 taxes a prohibited benefit: if a grant recommended from the fund produces a more than incidental benefit to the donor, advisor or a related person — a bifurcated payment that discharges the donor's personal pledge, or tickets and a table at a gala — the person who advised it faces a 125% tax and the fund manager a 10% tax.

The US numbers deserve naming, because they are punitive rather than compensatory: §4941(a) charges the self-dealer 10% of the amount involved and a knowing foundation manager 5%, and §4941(b) adds 200% on the self-dealer and 50% on the manager where the transaction is not corrected. The single gap in that wall is §4941(d)(2)(E): a foundation may pay a disqualified person for personal services that are "reasonable and necessary to carrying out the exempt purpose of the private foundation", provided the compensation "is not excessive". Salaries and professional fees can pass through that door. A sale, a lease or a loan cannot, however favourable the terms are to the foundation.

The United Kingdom polices the same boundary from the opposite end — it takes the relief away from the donor instead of taxing the transaction. The tainted charity donation rules in Part 13 Chapter 8 of the Income Tax Act 2007 (ss.809ZH–809ZR, introduced by Finance Act 2011 in place of the old substantial donor regime) bite where three conditions are met. Condition A (s.809ZJ(2)) asks whether a linked person entered into arrangements such that "the donation would not have been made and the arrangements would not have been entered into independently of one another". Condition B (s.809ZJ(5)) asks whether a linked person who is not a charity "receives financial assistance ... directly or indirectly from the charity to which the donation is made or from a connected charity". Condition C (s.809ZJ(6)) carves out charity-owned companies and certain housing providers. Where a donation is tainted, s.809ZM removes the relief for the same tax year and s.809ZMA claws it back in a later one.

What you got back decides what you gave. The line runs through the deduction itself as well, and two Supreme Court decisions set the test. In United States v. American Bar Endowment (Supreme Court of the United States, 23 June 1986, No. 85-599, 477 U.S. 105) the Court held that a taxpayer making a "dual payment" may deduct only the excess of the payment over the market value of the benefit received, and only where the taxpayer "purposely contributed money or property in excess of the value of any benefit he received" — the members lost, because they could not show that comparable insurance cost less. In Hernandez v. Commissioner (Supreme Court of the United States, 1989, No. 87-963, 490 U.S. 680) the Court applied the same structural analysis to payments for religious auditing and training, holding that §170 gives no special preference to payments made in expectation of a religious benefit and that "the external features of the ... transactions strongly suggest a quid pro quo exchange." Read together they explain why the gala table and the auction lot are not philanthropy: the deduction stops at fair market value, and inside a DAF the residue is worse than merely non-deductible — it is the §4967 prohibited benefit.

The through-line: a grant that routes money to a family member's organisation, discharges a family member's binding pledge, or buys the family goods, tickets or influence is not philanthropy the tax system will subsidise, however charitable the ultimate cause.

Changing the purpose, ending the structure

Restricted charitable capital is deliberately hard to redirect — that rigidity is what makes a restriction worth anything. When the original purpose becomes impossible, unlawful, wasteful or simply obsolete, the answer is not that the donor takes the money back; it is a supervised change of purpose that stays as close as possible to the original intent. The common-law name is cy-près.

In England and Wales, the Charities Act 2011 (s.62, refined by the Charities Act 2022) lists the occasions when purposes may be altered cy-près: where they have been fulfilled or cannot be carried out, where they no longer provide a suitable and effective use of the property, or where the original area or class of beneficiary has ceased to be suitable — always judged against the spirit of the gift. The change is made by a Charity Commission scheme, not by the trustees alone.

The US endowment analogue is UPMIFA. A donor-imposed restriction can be released or modified with the donor's written consent; failing that, a court may modify a restriction that has become impracticable, wasteful, impossible or unlawful, on notice to the Attorney General and consistent with the donor's intent. For a small, old fund — the uniform default is a fund under US$25,000 and more than 20 years old, though some states set a higher ceiling — the institution itself may modify the restriction after notifying the Attorney General.

Civil-law foundations reach the same result through their supervisory authority. A Swiss foundation's purpose may be changed by the competent authority under art. 86 ZGB where the original object has altered so much in significance or effect that the foundation has become estranged from the founder's intent; under art. 86a the founder can change the purpose only if that right was reserved in the deed and at least ten years have passed since establishment or the last change — and a public-benefit purpose must remain public-benefit. Liechtenstein is stricter on founder power: the right to amend the deed or revoke the foundation exists only where reserved in the founding deed, is personal to the founder and non-inheritable, and exercising it can push the foundation into "controlled" status with tax and asset-protection consequences.

Four situations

The mechanics above resolve the recurring hard cases. Each turns on separating a legal obligation from a preference, and a restriction from a right of return.

The recipient breaks the purpose. A grantee spends restricted funds on something else. The grant agreement, not sentiment, governs: the grantor withholds further tranches and invokes the repayment covenant. A US foundation under expenditure responsibility must, in addition, report the diversion and take reasonable steps to recover the funds and secure their proper use — or the grant becomes a taxable expenditure. Where the recipient is itself a charity whose trustees misapplied the money, its regulator adds a second track: in England the Charity Commission expects the trustees to pursue recovery and can hold trustees who acted deliberately or recklessly personally liable to restore the loss.

The original purpose becomes impossible. A disease is cured, an institution closes, a cause is fully provided for by the state. The capital is not released to the donor or the heirs; it is redirected cy-près — by Charity Commission scheme, by court order under UPMIFA, or by the supervisory authority in a civil-law foundation — to the nearest purpose consistent with the original intent.

A foreign recipient is not recognised for a deduction. The recipient's home-country charity status does not travel. The grantor either obtains an equivalency determination or exercises expenditure responsibility, or the individual donor gives through a domestic intermediary. A direct wire on the strength of a foreign charity certificate produces neither a clean deduction nor, for a foundation, a qualifying distribution.

The donor and the board disagree. A living founder wants the foundation to fund a cause the board considers outside the mission or imprudent. Here the distinction is everything. If the founder reserved a legal power — a retained amendment right, a designated protector role, board control written into the constitution — it is exercisable within its terms. If the founder holds only moral authority, or in a DAF only advisory privileges, the board's fiduciary duty runs to the foundation's purpose and the sponsor's legal control governs; the founder's wish is a preference the fiduciaries may decline. Advisory weight is not a veto.

Where this is heading

Professionalisation. UBS records a shift from administering grants to coordinating impact across all of a family's assets; 27% of offices say they work on systemic causes rather than one-off relief.

The next generation is already inside. Exponent Philanthropy's 2026 report finds that 71% of family foundations involve next-generation members: 60% as board members, 25% in leadership roles, 24% through junior and advisory boards.

Jurisdictions compete for philanthropic capital directly. Since 2023 Singapore has offered family offices under the 13O and 13U regimes a 100% deduction for overseas donations made through a qualifying local intermediary, capped at 40% of statutory income — conditional on hiring a philanthropy professional and on additional local business spending; the details are set out in the article on the 13O regime. The UAE took a different route: a closed list of Qualifying Public Benefit Entities (Cabinet Decision No. 37 of 2023) — such bodies are exempt from corporate tax, and donations to them are not treated as non-deductible expenditure under art. 33 of the corporate tax law. The form itself is flexible: a DIFC Foundation can be established for charitable objects as well, with no minimum capital requirement but with a mandatory guardian.

And the flip side. The louder the mission is proclaimed, the higher the cost of any gap between the impact promised and the impact measured. Impact washing is a concrete risk: the questions start with the assets funding the foundation.
