Swiss Foundation for UK Residents: Benefits and the UK Tax Reality

By Hansruedi Mueller, Swiss foundation lawyer · Published 4 June 2026 · Last updated 4 June 2026

A Swiss foundation (Stiftung) is an autonomous legal entity in which assets are irrevocably dedicated to a defined purpose; under the Swiss Civil Code, Article 80, it acquires its own legal personality. For a UK resident, the more important point comes next: a Swiss foundation does not let you avoid UK tax. UK anti-avoidance law is built to look through offshore structures and tax the UK person behind them.

This guide explains what a Swiss foundation can and cannot do for someone connected to the United Kingdom, a UK national, a UK resident, an expat, or a returning resident, and why competent UK and Swiss advice, taken together, is essential before you act.

Caution. This article is general information, not UK or Swiss tax or legal advice. A Swiss foundation is not a UK tax-avoidance tool. Your UK tax position depends on your own facts and must be confirmed by a qualified UK adviser.

Key takeaways

• A Swiss foundation is a legal entity (ZGB Art. 80). UK law has no “foundation” category, so HMRC treats it as the English-law entity it most closely resembles, often a trust.
• A Swiss foundation does not avoid UK tax for a UK resident: the Transfer of Assets Abroad rules, the settlements legislation and capital-gains attribution can all apply.
• The non-dom remittance basis was abolished from 6 April 2025; the new four-year FIG regime gives only a time-limited shelter to qualifying new arrivals.
• From 6 April 2025, inheritance tax is residence-based; a long-term UK resident is within worldwide IHT, and foundation assets treated as a trust can face 10-year and exit charges.
• This is general information, not advice, take UK + Swiss professional advice first.

Why UK residents consider a Swiss foundation

The interest is understandable. Switzerland is a stable, internationally respected jurisdiction, and a Swiss foundation offers genuine, legitimate advantages: durable asset protection, structured succession across generations, a credible home for philanthropy, confidentiality, and disciplined family-office governance. A Swiss family foundation (Familienstiftung) can carry a family’s intentions forward for decades.

Many people who search for “how to set up a foundation in the UK” discover that the UK has no close domestic equivalent to a continental private foundation. A UK resident who wants a foundation in the civil-law sense usually looks abroad, to a Swiss Familienstiftung or a Swiss charitable foundation. The question, then, is not only how to establish one, but how a UK resident relates to a Swiss foundation once it exists.

Here is the honest pivot. The structural benefits above are real. But your UK tax position travels with you. A Swiss foundation changes where assets sit; it does not move a UK resident outside the reach of HMRC. To see why, you first have to understand how HMRC even sees a foundation. Our foundation vs trust comparison sets out the underlying distinction in detail; this article applies it to the UK tax frontier.

How HMRC characterises a Swiss foundation, trust or company?

UK tax law contains no category called “foundation.” When a foreign entity appears, HMRC and the courts apply a resemblance test: they identify the English-law entity that the foundation most closely resembles, judged by its actual characteristics. The label given to the entity under its home law, “Stiftung”, “foundation”, is not decisive.

Because a Swiss family or private foundation holds assets for the benefit of defined beneficiaries under a governing deed, it is often treated as a trust, what UK law calls a “settlement”. In some cases, a foundation with strongly company-like features could instead be treated as a company, engaging a different set of rules. The outcome depends on the specific foundation deed, and even on the particular tax in question, since different taxes can characterise the same entity differently.

This is not a technicality to skim past. Characterisation decides which UK anti-avoidance regime applies to you. It must be assessed on your actual documents by a UK adviser, not assumed.

UK anti-avoidance: why a Swiss foundation does not escape UK tax

The UK has a layered set of rules whose express purpose is to tax UK residents who divert income, gains or assets into offshore structures. A Swiss foundation does not sit outside them.

Transfer of Assets Abroad (ToAA)

The Transfer of Assets Abroad rules sit in sections 714–751 of the Income Tax Act 2007 (ITA 2007). HMRC’s own manual explains their purpose plainly: income tax “could easily be avoided by individuals who are UK resident if they arranged for income to accrue to a person resident abroad, whilst still being able to enjoy the benefit of this income.” The rules stop exactly that. A Swiss foundation is the “person abroad.”

There are three charges:

• Section 720, the income charge. A UK-resident person who has the power to enjoy income that has become payable to the foundation can be taxed on it, even if they have not actually received it. The power to enjoy is enough.
• Section 727, capital sums. A corresponding charge where the individual receives a connected capital sum.
• Section 731, the benefits charge. This catches UK residents, typically beneficiaries, who receive a benefit from the structure, even if they did not transfer the assets in.

There are defences, but they are narrow: broadly, that avoiding tax was not a purpose of the arrangement, or that the transactions were genuine commercial transactions not designed for tax avoidance. Wealth-planning structures rarely satisfy these cleanly. A temporary EU-related exemption was repealed from 6 April 2025, narrowing the rules further.

The settlements legislation

If the foundation is treated as a settlement and you, your spouse or civil partner can benefit from it, the settlements legislation (section 624 of the Income Tax (Trading and Other Income) Act 2005) treats the foundation’s income as your own income. Section 624 provides that income arising under a settlement is treated as the income “of the settlor and of the settlor alone” where it arises during the settlor’s life from property in which the settlor has retained an interest.

Capital gains, sections 86 and 87

Capital gains are attributed too, under the Taxation of Chargeable Gains Act 1992 (TCGA 1992):

• Section 86 attributes the offshore structure’s gains to a UK-resident settlor who has an interest in it. HMRC’s manual states the purpose is “to prevent UK individuals avoiding a charge to CGT simply by holding assets through an offshore trust.”
• Section 87 applies where section 86 does not, matching the structure’s gains to capital payments received by UK-resident beneficiaries. Gains carried from earlier years can attract a supplementary charge, effectively raising the rate.

The pattern is consistent: whether you are the founder or a beneficiary, the foundation’s income and gains can be taxed in your hands.

The 2025 non-dom reform and what it means

For decades, non-UK-domiciled residents could use the remittance basis to keep foreign income and gains outside UK tax unless brought into the UK. That regime was abolished from 6 April 2025, and domicile was removed as the connecting factor for personal taxation of foreign income and gains.

In its place is the Foreign Income and Gains (FIG) regime. A qualifying new resident, broadly, someone in one of their first four years of UK residence after at least 10 consecutive tax years of non-UK residence, can claim relief on foreign income and gains arising in their first four tax years of residence, whether or not the money is brought to the UK. A claim must be made each year. After the four-year window, the individual is taxed on worldwide income and gains. The regime is in force as at June 2026.

The implication for a Swiss foundation is direct. The FIG regime is a personal, time-limited relief that a foundation neither creates nor extends. A long-settled UK resident gets no remittance-style shelter at all, and a recent arrival’s shelter expires after four years regardless of any structure. If you are within that narrow window, the interaction is genuinely complex and demands bespoke UK advice.

Inheritance tax and the foundation

Inheritance tax (IHT) also moved to a residence basis from 6 April 2025. Domicile and deemed domicile no longer determine IHT exposure; long-term residence does.

You are a long-term UK resident if you have been UK tax resident for at least 10 of the previous 20 tax years. A long-term resident is within IHT on their worldwide assets. Even after leaving the UK, that exposure persists for an “IHT tail” of three to ten years, depending on how long you were resident.

If a Swiss foundation is treated as a trust, two further consequences follow. Endowing it can be a chargeable lifetime transfer. And the foundation’s assets can fall within the relevant-property regime, which imposes IHT charges of up to 6% on each ten-year anniversary, plus exit charges when assets leave. In other words, for a long-term UK resident, a Swiss foundation does not remove assets from UK inheritance tax, and may add a layer of periodic charges. The detailed transitional rules here are intricate and must be checked individually.

Reporting obligations, secrecy is not a benefit

A common misconception is that a Swiss foundation offers UK residents privacy from HMRC. It does not.

• A UK-resident settlor or beneficiary of a non-resident structure may need to file a Self Assessment return and report attributed income, gains or benefits. Registration and disclosure obligations may also apply to the structure itself.
• Switzerland and the UK both participate in the OECD Common Reporting Standard (CRS), under which Swiss financial-account information is automatically exchanged with HMRC.
• Offshore non-compliance attracts elevated penalties. Failing to disclose is a serious risk, not a saving.

The right posture is full, accurate disclosure, built into the structure from the outset.

When a Swiss foundation can still make sense

None of this means a Swiss foundation is wrong for a UK-connected person. It means the reasons must be non-tax reasons, properly advised and fully disclosed:

• Genuine philanthropy. A Swiss public-utility (charitable) foundation is a credible, durable vehicle for charitable purpose. (A Swiss foundation is generally not a UK charity, so UK charity tax reliefs are a separate question.)
• Succession and governance continuity across generations and jurisdictions, under the Swiss foundation law in Articles 80–89c of the Civil Code and, for family arrangements, Article 335.
• Asset protection and segregation within a stable, respected jurisdiction, a frequent goal for expats using Swiss foundations for asset protection.
• Non-UK family branches. UK exposure attaches to the UK person; family members who are not UK-connected may have a different position.
• A narrow FIG window. A recent arrival within the four-year relief period may have specific, time-limited options, exactly where tailored advice matters most.

The UK-Switzerland double tax treaty may provide some relief on double-taxed income in specific circumstances, but it does not override the ToAA rules or the settlements legislation, and its application to foundation structures requires individual analysis by a UK adviser.

If you decide to proceed, the practical mechanics of establishment are covered in our guide to setting up a Swiss foundation as a foreigner.

Get UK and Swiss advice, both, together

The single most important step is to take advice on both sides of the border at once. A UK tax adviser must assess characterisation, ToAA, the settlements and CGT rules, IHT and reporting against your personal facts. Swiss foundation counsel must structure the foundation correctly under Swiss law. Neither alone is sufficient; the value is in the two working together.

Frequently asked questions

Does a Swiss foundation help a UK resident avoid UK tax? No. UK anti-avoidance law, the Transfer of Assets Abroad rules, the settlements legislation and capital-gains attribution, is designed to tax UK residents on income, gains and benefits arising in offshore structures. A Swiss foundation does not place a UK resident outside UK tax. Always take UK advice.

Is a Swiss foundation a trust or a company for UK tax? UK law has no “foundation” category, so HMRC characterises it by which English-law entity it most closely resembles. A Swiss family or private foundation is often treated as a trust (a “settlement”), though a strongly company-like foundation could be treated as a company. It depends on the specific deed and on the tax in question, and must be assessed by a UK adviser.

Can a UK resident set up a Swiss foundation? Yes. Swiss law allows non-residents, including UK nationals and residents, to establish foundations. But the UK tax position follows the UK person: the foundation’s income, gains and assets can be taxed or reported in the UK. Structure it for non-tax reasons, with UK and Swiss advice.

Did the 2025 non-dom changes affect Swiss foundations for UK people? Yes. The remittance basis was abolished from 6 April 2025 and replaced by the four-year FIG regime for qualifying new residents. A Swiss foundation does not recreate or extend that relief, and long-settled UK residents are taxed on worldwide income and gains.

Do I have to tell HMRC about a Swiss foundation? Generally yes. A UK-resident settlor or beneficiary may need to file Self Assessment and report attributed income, gains or benefits, and registration or disclosure obligations may apply. Switzerland also exchanges financial-account information with HMRC automatically under the Common Reporting Standard. Non-disclosure carries significant penalties.

How does HMRC treat a Swiss foundation differently from a trust? HMRC has no “foundation” category and applies a resemblance test. A Swiss private or family foundation is most often characterised as a trust (a “settlement”) because it holds assets for the benefit of defined beneficiaries under a governing deed. However, a foundation with strongly company-like features, for example, one that issues something akin to shares or certificates of participation, could instead be treated as a company, engaging different anti-avoidance rules such as the controlled foreign company regime rather than the ToAA or settlements legislation. Characterisation is fact-specific and must be confirmed by a qualified UK adviser.

Can a UK resident be a beneficiary of a Swiss foundation without being the founder? Yes. Under section 731 of the Income Tax Act 2007 (the ToAA benefits charge), a UK-resident beneficiary who receives a benefit from an offshore structure can be taxed on it even if they did not transfer any assets into the foundation. The charge applies to benefits in money or money’s worth. It is not limited to the original founder, so a UK-connected person who simply inherits a beneficiary position may still face a UK tax charge on distributions or benefits they receive.

What is the four-year FIG regime and how long does it last? The Foreign Income and Gains (FIG) regime replaced the remittance basis from 6 April 2025. A qualifying new resident, broadly someone in the first four tax years of UK residence after at least ten consecutive years of non-UK residence, can claim relief so that foreign income and gains arising in those four years are not charged to UK tax, whether or not the money is remitted. The relief is personal and time-limited: after four years it expires entirely. A Swiss foundation does not create, extend or renew this window, and a long-settled UK resident is not eligible for it at all.

Can a UK resident still use the remittance basis to shelter a Swiss foundation’s income? No. The remittance basis was abolished from 6 April 2025 for all UK residents. Any foreign income or gains arising on or after that date are taxable in the UK regardless of whether they are brought here. Only the narrow, time-limited FIG regime remains for qualifying new arrivals. A Swiss foundation cannot replicate or substitute for the old remittance basis.

Does the UK-Switzerland double tax treaty protect a Swiss foundation’s income from UK tax? The UK-Switzerland double tax treaty may provide some relief on income that is taxed in both countries in specific circumstances, but it does not override the Transfer of Assets Abroad rules, the settlements legislation, or the capital-gains attribution provisions. Whether the treaty applies to a particular income stream from a foundation depends on how the foundation is characterised and how the income is classified, and must be analysed by a qualified UK adviser. The treaty is not a general shelter from UK anti-avoidance rules.

Does setting up a Swiss foundation affect UK inheritance tax on death? It can, in both directions. If you endow a Swiss foundation while UK-resident, and it is treated as a trust, the transfer may be a chargeable lifetime transfer for IHT purposes rather than an exempt one. The foundation’s assets can then fall within the relevant-property regime, attracting ten-year anniversary charges of up to 6% and exit charges when assets leave. However, assets genuinely and irrevocably committed to the foundation are no longer yours on death. The net IHT picture is complex and turns on your own residence history, the foundation’s characterisation, and transitional rules, individual advice is essential.

What happens to a Swiss foundation’s UK tax position when the UK-resident founder dies? The ToAA and settlements rules that applied during the founder’s lifetime generally cease to apply after death because the “transferor” is no longer UK-resident. Section 87 of the Taxation of Chargeable Gains Act 1992 can then continue to attribute stored gains to UK-resident beneficiaries who receive capital payments. The foundation itself continues as before under Swiss law, but the UK tax profile of its beneficiaries becomes the operative concern. Any UK beneficiary needs their own UK advice on their ongoing position.

Is a Swiss charitable foundation treated differently from a private family foundation for UK tax? The characterisation principle, resemblance to a trust or company, applies to both. In practice, a charitable foundation is somewhat more likely to be distinguished from a typical settlement if its deed closely resembles a UK charitable trust operating for public benefit. However, a Swiss foundation is generally not a UK charity, so UK charitable tax reliefs (Gift Aid, charitable-company exemptions) do not automatically apply. Family and private foundations that benefit identifiable individuals are more squarely within the trust-characterisation path and the associated anti-avoidance rules.

How should I set up a Swiss foundation if I am a UK resident? The process under Swiss law, drafting a deed, registering with the commercial register, endowing assets, is the same regardless of your nationality or residence. What differs is the UK tax analysis that must accompany every step. Before you sign anything, a UK tax adviser should confirm the characterisation, assess the ToAA, settlements, CGT and IHT implications, and advise on any required reporting. Swiss foundation counsel handles the Swiss-law structure. The two advisers should work together, because decisions made under Swiss law can have direct and immediate UK tax consequences.

Disclaimer

This article is general information, not UK or Swiss tax or legal advice. UK tax treatment depends on your individual circumstances and the specific terms of any foundation, and the law changes. A Swiss foundation does not avoid UK tax for a UK-resident or long-term-UK-resident individual. Before establishing or relying on any cross-border structure, obtain professional advice from both a qualified UK tax adviser and Swiss foundation counsel.
