Charitable Foundations

Swiss Charitable Foundation Tax Exemption Requirements

A Swiss charitable foundation is tax-exempt only if it cumulatively meets a defined set of public-utility conditions, it serves an open circle of beneficiaries, dedicates its funds exclusively and irrevocably to that purpose, acts altruistically, and genuinely pursues its aims in practice. Exemption is not automatic: it must be applied for, and the cantonal tax authority decides. This guide explains each requirement in detail, and what disqualifies a foundation.

Key takeaways

• Tax exemption rests on five cumulative conditions: exclusive use of funds, irrevocable dedication, actual activity, a general-interest purpose with an open beneficiary circle, and altruism (no self-interest).
• The legal basis is Article 56, letter g of the Federal Direct Tax Act (DBG) and the parallel Article 23 of the Tax Harmonisation Act (StHG), interpreted through the Federal Tax Administration’s Circular No. 12 of 8 July 1994.
• A purpose limited to a single family, an association’s members, or one profession is too narrow, which is why family foundations generally do not qualify.
• The statutes must contain an asset-lock clause: on dissolution, remaining assets pass to another tax-exempt entity with a similar purpose.
• Exemption is applied for, not granted automatically, and the foundation bears the burden of proving it qualifies.

Overview: what the law requires

Tax exemption for a charitable, in German, gemeinnützige (public-utility), foundation is governed by Article 56, letter g of the Federal Act on Direct Federal Taxation (Direkte Bundessteuer, DBG) at federal level, and by the identical Article 23, paragraph 1, letter f of the Tax Harmonisation Act (Steuerharmonisierungsgesetz, StHG) at cantonal and municipal level. Both rest on the same underlying foundation law in the Swiss Civil Code Articles 80–89c.

Federal Direct Tax Act, Article 56, letter g Legal entities pursuing public or public-utility purposes are exempt from tax liability “for the profit that is exclusively and irrevocably dedicated to those purposes.”

That single sentence carries two of the core tests, exclusivity and irrevocability, but the full picture comes from practice. The Federal Tax Administration (Eidgenössische Steuerverwaltung, ESTV) set out the conditions in Circular No. 12 of 8 July 1994, the reference document for cantonal tax offices.

Three points frame everything that follows. First, the requirements are cumulative, a foundation must satisfy all of them. Second, exemption is decided by the cantonal tax authority of the foundation’s registered seat, so cantonal practice matters (we compare the leading options in our guide to the best Swiss cantons for a charitable foundation). Third, the burden of proof lies with the foundation claiming exemption.

This article concentrates on the criteria. For the application workflow itself, see our Swiss charitable foundation tax-exempt setup guide; for the resulting exemption rates and wider planning, see Swiss foundation tax benefits and exemption rates.

The core requirements, one by one

To qualify for exemption on the ground of public utility, a foundation must meet all five of the following conditions cumulatively.

1. Exclusive use of funds (Ausschliesslichkeit)

The exempt activity must be directed exclusively at the public task or the welfare of third parties. The foundation’s purpose may not be tied to commercial aims or to the private interests of the foundation, its members, or its founder. Where a foundation pursues both genuinely public-utility purposes and other purposes, full exemption is unavailable, though a partial exemption may apply to the qualifying part alone.

2. Irrevocable dedication (Unwiderruflichkeit)

Funds dedicated to the exempt purpose must be bound to it for ever. Any reversion to the founder or donors must be permanently excluded. This is the same irrevocable dedication that defines a Swiss foundation at formation: once committed, the assets belong to the foundation. The practical expression of this rule is the asset-lock clause described below.

3. Actual activity (no capital-hoarding)

A purpose proclaimed only in the statutes is not enough, the foundation must genuinely pursue it. A foundation whose main activity is simply accumulating capital, building reserves that bear no reasonable relation to any future task (a Thesaurus-Stiftung), has no claim to exemption. Where activity takes place abroad, the foundation must be able to evidence it with activity reports and annual accounts.

4. General interest and an open beneficiary circle

The activity must serve the general interest, and the circle of beneficiaries must in principle be open. This is the decisive test in many cases. As the ESTV puts it, “too narrow a circle of beneficiaries, for example, limitation to the circle of a family, the members of an association, or the members of a particular profession, excludes tax exemption on the ground of public utility.” Geographic limits, by contrast, are permitted: a foundation may serve a specific region and still qualify.

5. Altruism and no self-interest (Uneigennützigkeit)

Public utility has a subjective element as well as an objective one: the activity must rest on public spirit, with members or third parties making a genuine sacrifice that subordinates their own interests. Self-help institutions and associations devoted to leisure or hobby activities lack this altruistic character and do not qualify. No economic or personal interest of the founder or donors may be served.

”Public utility” explained

Public utility (Gemeinnützigkeit), the quality that makes a foundation a Gemeinnützige Stiftung in German tax practice, covers activities that advance the common good. The ESTV cites charitable, humanitarian, health-promoting, ecological, educational, scientific and cultural work, including social care, the arts and science, teaching, the promotion of human rights, the protection of heritage, nature and animals, and development aid. The list is illustrative, not exhaustive; whether a given activity serves the general interest is judged against prevailing public values.

Two limits matter in practice. A commercial purpose is not, in principle, public-utility. Some economic activity is tolerated, but only where it is subordinate, a mere means to the charitable end, and not the foundation’s sole economic basis (a residential training home that runs a farm and workshop is the classic example). Entrepreneurial and holding purposes are likewise generally outside public utility; a charitable foundation may hold a controlling stake in a company only where it exercises no influence over that company’s management, which requires a clear separation between the foundation board and the company’s board. Political activity also tends to fall outside it: the Federal Supreme Court has held that collecting signatures for a popular initiative does not qualify as public-benefit, treating it as partisan rather than serving the general good.

Activity abroad can qualify. Federal law no longer confines the general interest to work carried out in Switzerland, so the worldwide activity of a Swiss foundation may be exempt where it serves the general interest and is altruistic, provided the foundation documents what it does. Cantonal practice has modernised in step: from 1 February 2024, Zurich treats charitable activity abroad on the same footing as domestic activity where it carries positive spill-over effects for Switzerland and is fully documented.

Irrevocability and no self-interest

The bar on self-interest runs through every decision a tax-exempt foundation makes. Assets dedicated to the purpose cannot return to the founder, and no founder, donor or board member may draw a private benefit from the foundation’s funds. This is why grant-making to “related parties” is scrutinised so closely.

One area has been clarified rather than relaxed. Historically, board service was expected to be honorary. Under Zurich’s practice from 1 February 2024, appropriate board remuneration, commensurate with the time and responsibility involved, approved by the supervisory authority and set out in the foundation’s documents, no longer prevents exemption. The principle is unchanged: the foundation must serve its purpose, not enrich those who run it. Reasonable pay for genuine work is compatible with that; disguised distributions are not.

Once these conditions are reflected in the statutes, the foundation can move to the application itself. We set out that workflow, what to file, with whom, and in what order, in the tax-exempt setup guide rather than repeating it here.

The asset-lock clause

The statutes must contain an unalterable asset-lock clause: on the foundation’s dissolution, any remaining assets must pass to another tax-exempt entity pursuing a similar purpose. This guarantees that funds, once dedicated to the public good, can never flow back to private hands, the structural expression of the irrevocability requirement.

Tax authorities treat three statutory clauses as essential:

1. A prohibition on distributing profits to founders, board members or related parties.
2. The irrevocable allocation of funds to the stated public-utility purpose.
3. The asset-lock: transfer of any remaining assets, on liquidation, to another tax-exempt entity with a similar purpose.

A foundation deed that omits any of these will, in practice, fail the review, so the clauses belong in the foundation deed from the outset, not as an afterthought.

What disqualifies a foundation, including family foundations

A foundation falls outside tax exemption where it fails any of the cumulative conditions. The most common disqualifiers are:

• Family foundations. A Familienstiftung serves a defined family, a closed circle, so it fails the open-beneficiary test and is generally taxable. Under Swiss Civil Code Article 335, a family foundation may only meet costs of upbringing, establishment or support of family members; it cannot serve general maintenance, and it cannot be made public-utility simply by widening its wording.
• Self-help and leisure bodies. Mutual-benefit associations and hobby or leisure clubs lack the required altruism.
• Commercial, entrepreneurial or holding purposes. A purpose aimed at earning income, or at controlling a business, is not public-utility; economic activity is acceptable only as a subordinate means to the charitable end.
• Political purposes. Partisan or campaigning activity generally does not qualify.
• Capital-hoarding foundations. A foundation that merely accumulates reserves without real activity fails the actual-activity test.

Where a foundation pursues a genuine public-utility purpose alongside a non-qualifying one, the authorities may grant a partial exemption covering only the qualifying part. In borderline cases, it is prudent to seek an advance ruling from the cantonal tax office before finalising the statutes, so that any wording problems surface before, not after, formation.

Frequently asked questions

What are the requirements for a Swiss charitable foundation to be tax-exempt? The foundation must cumulatively meet five conditions: it dedicates its funds exclusively to the purpose, dedicates them irrevocably, genuinely pursues the purpose in practice, serves the general interest through an open circle of beneficiaries, and acts altruistically without self-interest. The legal basis is Article 56, letter g of the Federal Direct Tax Act and Article 23 of the Tax Harmonisation Act, interpreted through ESTV Circular No. 12.

Is a Swiss charitable foundation automatically tax-exempt? No. Exemption is neither automatic nor unconditional. The foundation must apply to the competent cantonal tax authority and prove that it meets all the public-utility conditions; the burden of proof rests on the foundation.

Why don’t family foundations qualify for tax exemption? Because a family foundation benefits a defined family, a closed circle of beneficiaries. Tax exemption requires an open, indeterminate circle, so a purpose limited to one family fails that test. Family foundations are therefore generally subject to ordinary taxation.

What is the asset-lock clause, and is it mandatory? The asset-lock is a statutory clause requiring that, on dissolution, any remaining assets pass to another tax-exempt entity with a similar purpose. It is effectively mandatory: tax authorities treat it, together with a ban on profit distributions and the irrevocable allocation of funds, as an essential statutory clause for exemption.

Can a tax-exempt foundation earn income or run a business? Only to a limited extent. A commercial or entrepreneurial purpose is, in principle, incompatible with public utility. Economic activity is tolerated only where it is subordinate, a means to the charitable end rather than the foundation’s main purpose or sole economic basis.

Which authority decides whether a foundation qualifies for tax exemption? The competent cantonal tax authority at the foundation’s registered seat decides. Because cantonal practice varies, particularly on points such as board remuneration and overseas activities, the choice of canton can affect the ease of obtaining and maintaining exemption.

What is the legal basis for tax exemption of Swiss charitable foundations? At federal level it is Article 56, letter g of the Federal Act on Direct Federal Taxation (DBG). The parallel provision at cantonal and municipal level is Article 23, paragraph 1, letter f of the Tax Harmonisation Act (StHG). Both are interpreted in practice through ESTV Circular No. 12 of 8 July 1994.

What does “open beneficiary circle” mean in Swiss tax practice? It means the group of potential beneficiaries must in principle be indeterminate, anyone who falls within the described category may benefit, not a pre-defined set of named individuals or a single family. A circle restricted to one family, the members of an association, or a single profession is too narrow and disqualifies the foundation.

Can a foundation with geographically restricted activities still qualify for exemption? Yes. Geographic limits are expressly permitted: a foundation may restrict its activities to a particular region or municipality and still satisfy the open-beneficiary and general-interest tests. What the law excludes is restriction to a defined group of persons, not restriction to a defined area.

Can a Swiss foundation carry out public-utility activities abroad and remain tax-exempt? Yes, provided the activity genuinely serves the general interest and is altruistic, and the foundation documents what it does through activity reports and accounts. Federal law no longer confines the general interest to work in Switzerland. From 1 February 2024, Zurich treats charitable activity abroad on the same footing as domestic activity where it carries positive spill-over effects for Switzerland.

May a foundation board member be paid and still maintain tax exemption? Under updated Zurich practice (from 1 February 2024), appropriate board remuneration, commensurate with the time and responsibility involved, approved by the supervisory authority and recorded in the foundation’s documents, no longer prevents exemption. The key test remains unchanged: remuneration must reflect genuine work and must not constitute a disguised distribution of the foundation’s assets.

What is a Thesaurus-Stiftung and why does it fail the tax-exemption test? A Thesaurus-Stiftung is a foundation whose main activity is accumulating capital rather than actively pursuing its stated purpose. It fails the “actual activity” condition because tax exemption requires the foundation to genuinely carry out its purpose, not merely hold and grow assets. Reserves that bear no reasonable relation to a concrete future task will lead the tax authority to deny or withdraw exemption.

Can a foundation obtain partial tax exemption if it pursues both public-utility and non-qualifying purposes? Yes. Where a foundation pursues a genuine public-utility purpose alongside a non-qualifying one, the cantonal tax authority may grant a partial exemption covering only the qualifying activity and the funds dedicated to it. The non-qualifying part remains taxable.

Is it possible to obtain an advance ruling on tax-exempt status before the foundation is formed? Yes. In borderline cases it is prudent to request an advance ruling from the cantonal tax office before the statutes are finalised. This allows any wording problems to be identified and corrected before, rather than after, the foundation is registered, avoiding the need to seek a formal amendment later.
