Family office in Zurich: the Swiss federal framework at the heart of private banking

Zurich concentrates Switzerland's largest banks, many private and foreign banks, the SIX Swiss Exchange, insurers, reinsurers, independent asset managers, law firms and audit firms within a compact city with an international airport. For a family that runs its wealth actively — direct investments, private equity and real estate, bankable portfolios spread over several custodians — this ecosystem is the main reason to choose Zurich over smaller cantons. The trade-off is tax: Zurich has no special family office regime and its ordinary company and personal taxes are higher than in Zug or Schwyz. Many families therefore separate the questions of where the office operates and where the principals live.

Switzerland does not regulate the label 'family office'; it regulates functions. Under FinIA Article 2(2)(a), persons who manage solely assets of persons with whom they have business or family ties are outside the Act. FinIO Article 4 lists those ties: relatives in the direct line, collateral relatives up to the fourth degree, spouses and registered partners (and their relatives), coheirs, and portfolio managers controlled by such persons or by a trust or foundation set up for them — even if charitable entities are also beneficiaries. A single family office (SFO) built within these limits needs no FINMA licence. Professional trustees are treated in the same way: a private trust company serving only family trusts can stay outside the trustee licence.

Once an office manages assets for unrelated families on a commercial basis, it becomes a portfolio manager (or, for trusts, a trustee) under FinIA. Commerciality is presumed under FinIO Article 19 where gross earnings exceed CHF 50,000 a year, there are more than 20 contractual partners, or there is unlimited power of disposal over third-party assets above CHF 5 million; family-tie relationships are disregarded in the count. A licensed manager needs Swiss domicile and effective management, qualified managers of good repute, minimum capital of CHF 100,000, risk management and compliance, ongoing supervision by a FINMA-authorised supervisory organisation and an annual audit. Managing collective investment schemes above the FinIA Article 24 de minimis thresholds requires a manager of collective assets licence. An office that only advises clients other than the family must also consider FinSA conduct rules and, for client advisers of non-supervised firms, registration in a client adviser register.

Anti-money laundering is a separate analysis. A family office with powers of disposal over others' assets may qualify as a financial intermediary under AMLA unless an exemption for family or group relationships applies; where caught and not supervised by FINMA, it must join a recognised SRO and apply KYC, beneficial owner identification, record keeping and suspicious activity reporting. The new Legal Entities Transparency Act entered into force on 1 October 2026 and requires Swiss companies to report their beneficial owners to a federal register maintained by the Federal Office of Justice, with transitional deadlines for existing entities. Switzerland applies the CRS and FATCA, so each entity, trust and foundation in the structure must be classified and, where relevant, report.

Taxes shape the design. Canton Zurich abolished lump-sum (expenditure-based) taxation after a popular vote on 8 February 2009, effective 1 January 2010, so a principal living in Zurich is taxed on worldwide income and wealth at ordinary rates; families wanting the lump-sum regime typically live in a canton that still offers it (for example Zug, Schwyz or Geneva) and work in Zurich. Zurich voters rejected a reduction of the cantonal profit tax rate on 18 May 2025, leaving a combined effective company rate of roughly 19.5–19.6% in the city of Zurich, though participation relief largely removes tax on qualifying dividends and capital gains of a holding company. Zurich exempts spouses and direct descendants from cantonal inheritance and gift tax, and Swiss voters rejected a federal inheritance tax initiative on 30 November 2025. Switzerland has no domestic trust law but recognises foreign trusts under the Hague Trusts Convention, which is why Zurich offices often serve a common-law trust, a private trust company or a Liechtenstein foundation.
