A family office is a platform, not a structure
The expression "family office" describes an organised capability: a set of functions that a family performs consistently, with defined responsibility, defined reporting and defined decision-making. Those functions typically include investment oversight and manager selection, consolidated reporting across banks and jurisdictions, liquidity and treasury coordination, tax compliance oversight, coordination of legal and fiduciary advisers, administration of philanthropic activity, and the preparation and staging of succession.
None of those functions determines who owns anything. Ownership is determined by the vehicles beneath the platform: operating companies, holding companies, investment companies, foundations, and trusts governed by foreign law. A family office administers, monitors and coordinates. A vehicle holds, transfers and, on death or incapacity, continues.
Keeping the two layers distinct has practical consequences. Regulatory analysis, staffing, cost allocation and service agreements belong to the platform. Tax residence, treaty access, withholding tax, succession effects and forced-heirship exposure belong to the vehicles. An arrangement that answers only one of the two layers is incomplete, however well it is documented.
It is equally important to state what a family office is not. It is not a tax-reduction product, and a family whose motivation is limited to a reduction of the effective tax burden is unlikely to obtain a defensible or durable result. The economic case for a Swiss family office rests on control, continuity, quality of oversight, professional access and the orderly transmission of assets across generations. Tax and regulatory efficiency are constraints to be respected within that case — not the case itself.
Single-family and multi-family offices are different regulatory objects
A single-family office serves one family and manages assets that belong to that family. A multi-family office serves several unrelated families, and in commercial terms sells a service. The distinction is not descriptive: in Switzerland it determines whether the entity operates inside or outside the authorisation perimeter of the Financial Institutions Act (FinIA/LEFin/FINIG), which since 1 January 2020 subjects portfolio managers and trustees to licensing and prudential supervision.
FinIA does not apply to persons who manage assets exclusively for persons with whom they have family ties. The Financial Institutions Ordinance defines those ties with precision — including relatives by blood or by marriage in the direct line, relatives up to the fourth degree in the collateral line, spouses and registered partners, and further defined categories. The exemption is therefore a legal test with an identifiable boundary, not a general concession to private wealth.
The boundary is where the analysis becomes demanding. Extended families with branches that have separated over generations, unrelated business partners retained inside a shared vehicle, in-laws after a divorce, key executives admitted to a co-investment programme, and "friends of the family" invited into a club deal are all situations in which the composition of the client base can move outside the definition without anyone taking a decision to that effect. Where it does, the activity may require authorisation as a portfolio manager, with the corresponding organisational, capital, personnel and audit requirements, and affiliation with a supervisory organisation.
The composition of the served group therefore needs to be monitored as a live compliance parameter rather than assessed once at incorporation. In our experience this is the single most common regulatory drift in family office arrangements: the structure was correctly outside the perimeter when it was created, and no one re-examined the position when the family, or the circle around it, changed.
What actually triggers authorisation
The trigger is the activity, not the label on the door. Managing assets on the basis of a mandate, on a commercial basis, for persons outside the exempt circle is the paradigm case. Acting as trustee of a trust governed by foreign law is separately captured: FinIA subjects trustees to authorisation, again subject to the defined exemptions, so a family that intends to keep the trustee function "in house" in Switzerland must analyse that function on its own terms and not as an incident of the family office.
Advisory-only arrangements, purely administrative services, accounting, consolidated reporting and the coordination of external managers do not, in themselves, constitute portfolio management. That is a genuine planning space, but it is narrower than it is often presented, because the question is whether discretionary decisions are in substance taken by the family office, irrespective of who signs the instruction. Where the family office selects, allocates, rebalances and instructs, describing the mandate as advisory does not change the characterisation.
Some families resolve the question by keeping discretionary management entirely with authorised external managers and confining the family office to oversight, reporting, controlling and coordination. Others accept the licence and build a supervised entity, which can be the right answer where the family intends to serve several branches, admit unrelated participants, or eventually operate as a multi-family office. Both are legitimate; what is not legitimate is remaining ambiguous about which of the two has been chosen.
The Financial Services Act (FinSA/LSFin/FIDLEG) operates on a different axis: it governs conduct at the point of interaction with clients — classification, information, suitability and appropriateness, documentation and accountability. Where the family office provides financial services to persons who qualify as clients, the conduct duties apply according to the classification of those clients, independently of whether the entity requires a FinIA authorisation.
Anti-money laundering duties
The Anti-Money Laundering Act (AMLA/LBA/GwG) applies to financial intermediaries. Whether a family office is one depends on what it does: accepting or holding assets belonging to third parties, or assisting in their investment or transfer, on a professional basis, is the relevant activity. A pure in-house office administering only the family's own assets is generally outside the concept; an entity that holds or moves assets for others, acts as trustee, or provides company formation and administration services to third parties, may fall inside it.
Where the duties apply, they are substantive: identification of the contracting party, establishment of the beneficial owner, clarification of the economic background of unusual transactions, documentation, organisational measures, and reporting obligations. Affiliation with a self-regulatory organisation or supervision under the applicable regime follows.
Even where a family office is outside the AMLA perimeter, it operates in an environment in which banks, custodians, insurers and administrators are inside it. The practical consequence is that the family will be asked, repeatedly and by several counterparties, to evidence source of wealth, source of funds, beneficial ownership and the rationale of the structure. Files that are assembled in advance — coherent, consistent across jurisdictions and capable of being updated — reduce friction and account-opening delay far more effectively than any explanatory letter written after a request has been made.
The Federal Council decided on 12 June 2026 to bring the revised Anti-Money Laundering Act into force on 1 October 2026, together with the new legislation on the transparency of legal entities. The revision is discussed in Part 3, because its practical significance for families lies principally in the identification and registration of beneficial owners.
Governance: the part that is not regulatory
The regulatory analysis defines what the family office may do. Governance defines whether it works. The two are routinely confused, and only the first is usually documented.
Effective governance for an international family normally requires: a written statement of the family's investment objectives and risk tolerance, and a defined process for revising it; a clear allocation of decision rights between family members, the family office and external managers, with thresholds; an investment committee or equivalent body that actually meets, with minutes; consolidated reporting on a defined periodicity, in a single currency, across all custodians and vehicles; a conflict-of-interest policy that covers related-party transactions and the remuneration of family members; and a defined procedure for incapacity and for death, which is where informal arrangements fail most visibly.
Philanthropy deserves its own line rather than being treated as a residual. A Swiss charitable foundation is subject to supervision, must pursue a public-interest purpose, and — where tax exemption is sought — must meet the conditions applied by the competent cantonal and federal authorities, including irrevocable dedication of assets to the charitable purpose. A family that intends to use philanthropy as a vehicle for family cohesion across generations should design the governance of that activity, including the involvement of the next generation, at the same time as the legal form.
Succession coordination is likewise a governance function before it is a legal one. The documents — wills, marriage contracts, shareholder agreements, foundation deeds, trust instruments, powers of attorney and advance care directives — must be consistent with each other and with the actual holding structure. Where they are drafted at different times, in different jurisdictions, by advisers who never speak to each other, inconsistency is the normal outcome rather than the exception.
Swiss corporate vehicles
The company limited by shares (Aktiengesellschaft / société anonyme) and the limited liability company (GmbH / Sàrl) are the ordinary vehicles for holding participations, investment portfolios and, where appropriate, the family office entity itself. They offer legal personality, transferable participation rights, a defined governance framework under the Code of Obligations, and access — subject to conditions — to Switzerland's treaty network.
For a holding function the relevant Swiss tax mechanism is the participation deduction, which reduces the tax on qualifying dividend income and on qualifying capital gains on participations, subject to the statutory thresholds and holding requirements. Since the 2020 reform of corporate taxation the former cantonal holding privilege no longer exists; the analysis is now conducted under the ordinary rules and the replacement measures adopted at cantonal level. It is a mistake, still frequently made in family planning documents, to describe a Swiss holding company as benefiting from a special holding status.
The family office operating entity is a different animal. It provides services, employs people, incurs costs and should be remunerated on arm's length terms by the entities or persons it serves. Where the office serves multiple related entities in several countries, the pricing of those services, the deductibility of the corresponding charges and the VAT treatment of intra-group services all require attention. Swiss VAT is not neutral in this setting: management and administrative services supplied for consideration are in principle taxable supplies, while certain financial-sector supplies are exempt without credit, so the composition of the service catalogue affects the recoverability of input tax.
Withholding tax remains a central constraint. Swiss withholding tax of 35 per cent applies in principle to dividends distributed by Swiss companies, with relief available through domestic notification procedures where applicable and through the applicable double taxation agreement or the Switzerland–EU agreement, subject to beneficial ownership, to the conditions of the relevant instrument and to anti-abuse rules. A structure that assumes treaty relief without verifying entitlement is exposed at the level of cash flow, not merely of assessment.
Foundations and associations
A Swiss foundation is an endowment of assets dedicated to a specific purpose. It has no members and no owners; once established, the founder does not retain ownership of the endowed assets, and the purpose can be amended only within the narrow limits permitted by the Civil Code. That characteristic is the reason foundations are effective for philanthropy and for long-term dedication — and the reason they are unsuitable as a general substitute for family ownership.
Swiss law expressly restricts family foundations. A family foundation may be established for defined purposes connected with the costs of upbringing, endowment, support of family members and similar objects; a foundation whose purpose is simply to maintain the family's wealth and distribute it to members according to discretion is not an available Swiss instrument. Families who have been shown structures presented as "Swiss family foundations" performing a discretionary distribution function should treat that presentation with caution and obtain a specific legal opinion.
The association (Verein / association) is occasionally used for governance purposes — for example as the membership body of a family council or as the carrier of a non-profit activity — but it is a membership organisation with a non-economic primary purpose and is not an ownership vehicle for family wealth.
For philanthropy, the ordinary Swiss route is a charitable foundation under federal or cantonal supervision, with tax exemption granted, where the conditions are satisfied, by the competent cantonal authority for cantonal and communal taxes and for direct federal tax. Exemption is neither automatic nor permanent: it depends on the actual pursuit of the public-interest purpose, on the exclusion of private benefit, and on continuing compliance, including reporting to the supervisory authority.
Trusts: foreign law, Swiss recognition
Switzerland does not have a domestic trust. There is no Swiss trust law under which a settlor can create a Swiss trust, and any presentation to the contrary is inaccurate. What Switzerland does have is recognition: as a party to the Hague Convention of 1 July 1985 on the Law Applicable to Trusts and on their Recognition, in force for Switzerland since 1 July 2007, Switzerland recognises trusts validly created under a foreign governing law, and the Private International Law Act contains the corresponding provisions on jurisdiction, applicable law and recognition of foreign decisions.
The legislative project to introduce a trust into Swiss substantive law did not result in legislation, and families should plan on the basis of the framework as it stands: a trust used by a Swiss-connected family is governed by a foreign law, is administered by a trustee whose activity may itself be subject to Swiss authorisation under FinIA where the trustee acts from Switzerland, and interacts with Swiss law principally at the level of recognition, of tax treatment and of succession.
The Swiss tax treatment of trusts does not follow from recognition. It follows from the characterisation of the trust and of the position of the persons connected with it. Swiss practice distinguishes broadly between revocable and irrevocable arrangements, and within irrevocable arrangements between those in which beneficiaries have fixed entitlements and those in which distributions are discretionary; the consequences for income tax, wealth tax and the taxation of distributions differ accordingly, and the analysis must be performed under the law and practice applicable to the actual settlor, trustee and beneficiaries. Where a settlor or a beneficiary is or becomes Swiss resident, the position must be examined before the move, not after it.
Trusts also interact with succession law in a way that is regularly underestimated. Recognition of a trust does not displace the compulsory-portion rules that may apply to the estate of a settlor, whether under Swiss law or under the law otherwise governing the succession. A transfer into trust may remain subject to challenge by protected heirs under the applicable succession regime, and the practical value of the arrangement depends on the interaction between the governing law of the trust, the law governing the succession and the place where enforcement would be sought.
Residence, effective management and substance
A company is resident in Switzerland for tax purposes if it has its registered office in Switzerland or if it is effectively managed in Switzerland. The second limb is factual: it looks at where the day-to-day management decisions of the entity are actually taken, as distinct from where shareholders' resolutions are formally adopted or where documents are signed.
This cuts in both directions for family offices. A Swiss-registered entity that is in reality directed from abroad may be treated by the other state as resident there, generating a dual-residence conflict to be resolved, where a treaty applies, by the applicable tie-breaker — increasingly by mutual agreement rather than by an automatic place-of-effective-management rule, following the amendments introduced by the Multilateral Instrument in the treaties concerned. Conversely, a foreign entity that is in reality directed from a Swiss family office may become taxable in Switzerland on that basis, which is a risk that materialises quietly when a family relocates and continues to run its foreign companies from its new home.
Substance is therefore not decoration. For a Swiss family office entity it normally means: premises, qualified personnel in Switzerland proportionate to the functions performed, board members able to take and evidence decisions, meetings actually held in Switzerland with contemporaneous minutes, separate accounting, its own bank relationships, and service agreements that correspond to what is really provided. Where functions are outsourced, the outsourcing must be documented and the entity must retain the capacity to supervise them.
Treaty access adds a further layer. The principal purpose test introduced through the Multilateral Instrument into a large number of Switzerland's treaties denies a benefit where obtaining it was one of the principal purposes of an arrangement, unless granting it would be in accordance with the object and purpose of the relevant provisions. For a family holding structure this means that the commercial and governance rationale must be real, contemporaneous and documented, rather than reconstructed at the time of a refund claim.
Automatic exchange: the revised CRS applies from 1 January 2026
International families are inside the automatic exchange of information regime, and the regime has changed. The amended Common Reporting Standard, together with the corresponding Swiss implementing amendments, entered into force in Switzerland on 1 January 2026, and the State Secretariat for International Finance and the Federal Tax Administration have since issued updated technical guidance, including guidance published in the course of 2026.
For a family office the operative points are structural rather than technical. Entities within a family structure must be classified — as financial institutions or as non-financial entities, and in the latter case as active or passive — and the classification determines who reports and who is reported. Passive non-financial entities are looked through to their controlling persons, which for a family holding company or a trust means that individual family members are identified and reported to their states of residence. A private investment company managed by a financial institution may itself be classified as a financial institution, with its own reporting obligations. Misclassification is a recurring source of remediation work, because it is usually discovered only when a custodian revisits the file.
The amendments also affect the scope of what is reported and the diligence expected in establishing tax residence and controlling persons. Families should expect renewed self-certification requests across their banking relationships during 2026, and should ensure that the answers given to different institutions, in different countries, about the same structure are consistent. Inconsistent self-certifications are among the most common triggers for enquiry.
Crypto-assets: CARF is a framework, not yet a Swiss exchange
The Crypto-Asset Reporting Framework has been transposed into the Swiss legal framework, but the timing must be stated precisely. According to the State Secretariat for International Finance, Switzerland will implement the Crypto-Asset Reporting Framework at the earliest from 1 January 2027, with activation depending on the decision of Parliament and on the partner states with which exchange is agreed.
For families holding digital assets, the planning consequence is not to wait. Data quality — wallet inventories, custody arrangements, acquisition records, valuation methodology and the identification of the entity that holds each position — takes longer to assemble than the reporting itself, and the Swiss income, wealth and, where applicable, VAT analysis of those holdings applies now, independently of any future exchange of information.
Beneficial-owner transparency: future law with a fixed date
On 12 June 2026 the Federal Council set 1 October 2026 as the date of entry into force of the revised Anti-Money Laundering Act and of the new federal legislation on the transparency of legal entities and the identification of beneficial owners, together with its implementing ordinance. As at 11 September 2026 this is future law: the framework is adopted and the date is fixed, but the obligations are not yet in force.
The direction is unambiguous. Swiss legal entities will be required to identify their beneficial owners and to report them to a federal register that is not public but is accessible to defined authorities, with sanctions for failure to comply and with a transitional period for existing entities. The reform is complemented, on the professional side, by extended duties for certain advisory activities in the context of corporate and real-estate structuring.
For an international family the preparatory work is concrete and can be done now: establish, for every Swiss entity in the structure, who the beneficial owners are under the applicable definition; verify that the answer is consistent with what has already been declared to banks and to foreign registers; identify the entities in the chain that will need to file; and allocate responsibility for filing, updating and evidencing the position. Structures involving foreign entities, foundations or trusts require a specific analysis, because the identification of the beneficial owner in those cases does not follow mechanically from a shareholding percentage.
Because the rules are not yet in force, no family should be advised to act as though a filing obligation already exists. The correct posture is readiness: the information assembled, the analysis performed, and the filing made when the obligation applies.
Cross-border succession: what a Swiss structure can and cannot do
Succession is where international families most often discover that their structure answers a different question from the one they asked. A Swiss holding company does not determine who inherits its shares. A Swiss family office does not determine which law governs an estate. Those questions are answered by the succession rules that apply to the deceased, which for an internationally mobile family may be the rules of more than one state.
Switzerland's Private International Law Act attributes jurisdiction and applicable law on the basis of the deceased's last domicile, with defined possibilities for a national of another state to subject the estate to the law of that state, and with specific rules for immovable property and for foreign proceedings. Where a family has connections to a European Union member state, the European Succession Regulation may apply on the other side of the border, with its own connecting factor of habitual residence and its own possibility of a choice of national law. Coordinating those two systems — and ensuring that a choice of law made in a will is effective under both — is a specialist exercise and should never be assumed.
Forced heirship is the substantive constraint. Swiss law provides compulsory portions for defined heirs, reduced by the succession law reform in force since 1 January 2023, which removed the compulsory portion of the parents and reduced that of descendants, thereby increasing the freely disposable quota. Other civil-law systems apply their own, sometimes more restrictive, protection, and some regard it as a matter of public policy. A structure that transfers assets during lifetime may reduce the estate, but transfers can be brought into account or reduced under the applicable law, and the enforceability of the result depends on where the assets and the heirs actually are.
The honest statement to an international family is therefore this: Swiss vehicles can organise ownership, professionalise administration, stage the involvement of the next generation and provide continuity on death or incapacity. They do not override foreign succession law, and any presentation suggesting that they do should be treated as a reason to seek a second opinion.
Building the structure in the right order
The sequence that works in practice begins with the family, not with the entities. First, establish the actual objectives — control, continuity, liquidity, philanthropy, protection of a vulnerable member, preparation of a sale — and the positions of the individuals concerned, including their tax residences, nationalities, matrimonial regimes and existing testamentary dispositions.
Second, map the assets as they are: what is held, where, by whom, under which law, with what encumbrances, and with what latent tax exposure on transfer. Families are routinely surprised by the results of this exercise, and it frequently changes the plan.
Third, decide the ownership layer, jurisdiction by jurisdiction and asset by asset, with the succession and transparency consequences analysed at the same time as the tax treatment. Fourth, and only then, design the platform: the perimeter of the family office, whether it stays outside the FinIA authorisation regime or accepts supervision, what it will do in-house and what it will outsource, how it will be staffed, priced and governed. Fifth, implement, document contemporaneously and review periodically — the composition of the served group, the substance of each entity, the classification of entities for exchange-of-information purposes, and the consistency of the succession documents.
Timing matters most before a relocation, before a liquidity event and before a generational transfer. After any of those, the facts are fixed and the work becomes presentation rather than planning.
The TCC perspective
In our experience the structures that fail are rarely the aggressive ones. They are the fragmented ones: a company incorporated in one year for one reason, a trust established in another jurisdiction for another, a philanthropic vehicle created after a liquidity event, wills drafted in two countries by advisers who never spoke, and a family office assembled last to administer the result. Each element may be defensible on its own. The combination is frequently inconsistent, and inconsistency is what an authority, a bank or a disappointed heir will find first.
The second recurring failure is confusing form with function. A vehicle that performs no function, employs no one and takes no decisions does not create substance; a governance document that is never applied does not create governance; and a family office that exists on paper but whose decisions are taken elsewhere will be assessed on where the decisions are actually taken.
TCC Tax & Corporate Consultants SA approaches these mandates as a structure rather than as a collection of individual advisers, coordinating the Swiss tax and regulatory analysis with corporate implementation, fiduciary administration, transparency and reporting obligations, and the succession dimension, and cooperating with counsel in each of the other jurisdictions concerned. The objective is a family arrangement that is coherent in every state in which the family is present, capable of surviving a change of residence or a change of generation, and defensible on its facts.
