Switzerland occupies a singular place in the landscape of international wealth planning. Its centuries-old tradition of banking confidentiality (though substantially reformed under international transparency initiatives), its political neutrality, an exceptional quality of life, political stability, and — for qualifying individuals — the lump-sum (forfait) tax regime combine to make it the world's pre-eminent destination for the ultra-wealthy.
As of 2026, Switzerland is home to roughly 2.4 million foreign residents, representing approximately 26% of the population. The expatriate community is diverse — from European workers commuting to Zurich and Geneva, to family offices and HNW individuals seeking the benefits of the forfait regime, to international executives of the major global corporations headquartered there.
This guide focuses on the financial planning considerations for UK expats and HNW individuals considering Switzerland as a primary residence.
The Swiss Lump-Sum Tax Regime (Forfait)
The expenditure-based tax assessment (Aufwandbesteuerung in German, imposition d'après la dépense in French) — commonly known as the forfait — is one of the most distinctive tax regimes in the world. It allows qualifying individuals to pay Swiss tax based on their living expenses in Switzerland, rather than on their actual worldwide income and assets.
Who qualifies?
- Foreign nationals (non-Swiss) who are taking up Swiss residence for the first time, or who have not been Swiss residents in the preceding 10 years
- Who are not gainfully employed in Switzerland (i.e., they do not work in Switzerland — they are permitted to manage their own investments but may not be employed by a Swiss employer)
- Who therefore do not participate in the ordinary Swiss assessment system
How the tax is calculated:
The tax base is the individual's annual living expenditure in Switzerland, with a minimum of seven times the rental value (or rent paid) of the property they live in, subject to a minimum taxable base of CHF 434,700 (2026 federal minimum — cantonal minimums vary and are typically higher).
In practice, the negotiated tax bill reflects a lifestyle assessment by the cantonal tax authority. The individual declares their Swiss expenditure and the tax authority agrees an assessment.
Federal minimum rules (since 2016 reform): A national minimum taxable base of CHF 434,700 (2026) applies at federal level. Cantons have their own minimum bases, typically higher. (Note: Zurich abolished the lump-sum regime by cantonal referendum in 2009, so it is not available there.)
Effective tax rates: The combined federal, cantonal, and communal income tax on the assessed base depends on the canton. Switzerland's cantons vary significantly in their tax rates. Low-tax cantons historically popular with forfait taxpayers include:
- Schwyz: Among the lowest combined tax rates in Switzerland
- Nidwalden: Very low cantonal tax rates
- Zug: Low rates; also home to many international businesses
- Valais (Wallis): Popular for quality of life (ski resorts); moderate rates
For an individual assessed on CHF 600,000 of expenditure in a low-tax canton, the combined Swiss income tax bill might be in the range of CHF 80,000–130,000 per year, regardless of actual worldwide income or assets.
What forfait taxation does not cover:
- Swiss real estate: Annual wealth tax applies to Swiss property and may be separately assessed
- Swiss source income: If you receive any Swiss-source income, it is taxed under the ordinary regime
- Social Security: Voluntary Swiss AVS/AHV contributions may be made — and can be valuable for healthcare and pension purposes
Access to treaty benefits: Switzerland's double taxation treaty network is extensive (approximately 100 treaties). Historically, forfait taxpayers had limited access to Switzerland's DTAs, as treaty access requires that income is "taxed" in the conventional sense. Since 2014 reforms, Switzerland has renegotiated many treaties to extend DTA benefits to forfait taxpayers in specific circumstances — but this is treaty-by-treaty and advice is needed.
Swiss Residency
EU/EFTA nationals (and UK nationals under the UK-Switzerland bilateral agreement maintaining Bilateral I rights as of 2026) have relatively straightforward residency rights in Switzerland. For most other nationalities, the C permit (permanent residency) or B permit (renewable annual residency) routes are available, with the cantonal authority playing a significant role in approving forfait applications.
For HNW individuals seeking the forfait regime, the process typically involves:
- Identifying the most suitable canton (both for tax rate and lifestyle)
- Negotiating the tax assessment in advance with the cantonal tax authority (Vereinbarung)
- Obtaining the appropriate residence permit (cantonal authorities coordinate with federal immigration)
- Purchasing or renting suitable accommodation
Swiss Banking
Switzerland's banking sector remains one of the world's largest and most sophisticated, managing an estimated USD 2.5 trillion in offshore private wealth. Despite the end of strict banking secrecy (Switzerland now participates in the OECD's Common Reporting Standard, automatically exchanging financial account information with over 100 countries), Swiss private banks continue to offer unrivalled breadth of investment product, multilingual service, and discreet relationship management.
Major Swiss private banks include:
- Julius Baer (Geneva and Zurich)
- Pictet & Cie (Geneva — partnership structure)
- Lombard Odier (Geneva)
- Vontobel (Zurich)
- UBP (Union Bancaire Privée) (Geneva)
Universal banks with private banking divisions:
- UBS Wealth Management
- Credit Suisse (now absorbed into UBS following the 2023 emergency merger)
Account opening minimums at private banks typically start at CHF 500,000 to CHF 1 million in investable assets, with the most exclusive relationships requiring CHF 5 million+.
Multi-currency accounts, structured products, alternative investments, precious metals custody, art finance, and sophisticated FX services are standard features of Swiss private banking. Swiss banks' strength in wealth preservation over generations — managing portfolios through wars, currency crises, and market collapses — gives them a track record that newer financial centres cannot match.
CRS and FATCA compliance: Swiss banks automatically report account information to tax authorities of account holders' countries of residence under CRS. US persons are subject to FATCA reporting. Swiss banking is not a mechanism for hiding assets from tax authorities — it is a sophisticated wealth management platform, nothing more.
Wealth Tax in Switzerland
Switzerland levies an annual wealth tax on net assets — one of the few OECD countries to do so. The rate varies by canton but typically ranges from 0.1% to 1% of net assets.
Under the forfait regime, wealth tax may be applied to Swiss-situated assets (primarily Swiss real estate and Swiss bank assets) rather than worldwide assets, depending on the negotiated arrangement. In practice, many forfait taxpayers hold their investment portfolios offshore (in Guernsey, Jersey, Cayman Islands, or Luxembourg) partly to limit Swiss wealth tax exposure.
Property in Switzerland
Swiss property is expensive — among the most expensive in the world per square metre in prime locations. The Lex Koller Act restricts the right of foreign nationals to purchase residential property in certain designated "holiday resort" areas, but primary residences in most urban areas are purchasable by permit holders.
As of 2026, indicative prices:
- Zurich lake area (Zurichsee): CHF 15,000–30,000+/sqm
- Geneva (Genève): CHF 12,000–25,000+/sqm
- Zug: CHF 10,000–20,000/sqm
- Gstaad, St. Moritz, Verbier: CHF 20,000–50,000+/sqm
Property transaction costs (notary, land registry, cantonal taxes) vary by canton but typically total 2–5% of the purchase price.
Cost of Living
Switzerland is consistently ranked the world's most expensive country. A couple living comfortably in Zurich or Geneva might spend CHF 150,000–300,000 per year on accommodation, food, healthcare (mandatory private health insurance costs approximately CHF 8,000–15,000 per person per year), and lifestyle. For forfait taxpayers, this is typically the minimum lifestyle expenditure used to negotiate the tax base.
Estate Planning in Switzerland
Switzerland has no federal inheritance tax; cantonal inheritance taxes apply in most cantons (not all), at varying rates. Spouses are typically exempt; direct descendants face very low or zero rates in most cantons. More distant relatives or non-family beneficiaries face higher rates.
Swiss forced heirship rules under the Swiss Civil Code protect spouses and descendants. For non-Swiss nationals, the Hague Convention on succession and international private law principles may allow application of home-country law to Swiss estates in some circumstances.
Financial Planning Checklist for Switzerland Expats
- Identify the optimal canton for lifestyle, tax rate, and forfait assessment
- Engage a Swiss tax specialist to negotiate the forfait assessment before arrival
- Obtain the appropriate residence permit
- Find qualifying accommodation (purchase or rent)
- Open Swiss bank accounts and consider the private banking relationship
- Structure offshore investment portfolio to minimise Swiss wealth tax
- Ensure home-country departure is correctly managed (HMRC notification; UK Statutory Residence Test)
- Understand treaty access for your specific circumstances
- Consider Swiss AVS voluntary contributions for healthcare and pension
- Draft a Swiss will and coordinate with home-country estate plan
Compliance Reminder
The forfait regime requires genuine residence in Switzerland and a bona fide lifestyle assessment. It is not a mechanism to claim Swiss tax residency while actually living elsewhere. Swiss cantonal tax authorities and the OECD's standards mean that sham arrangements are discoverable and risky.
