Switzerland attracted a net inflow of 3,000 migrating millionaires in 2025, according to Henley & Partners — a figure that places it among Europe’s top wealth destinations alongside Italy and Portugal. Much of this appeal traces back to a single policy: the forfait fiscal, or lump-sum tax regime, which allows qualifying foreign nationals to settle their Swiss tax liability on a notional base of living expenses rather than worldwide income or assets. For HNWIs exploring European residency in 2026, few arrangements come close to the efficiency and predictability of the Swiss lump-sum.
Key Takeaways
- Switzerland’s forfait fiscal applies to non-Swiss nationals who are new to Swiss residency and do not engage in gainful activity in the country.
- The federal minimum taxable base for 2026 is CHF 435,000 — tax is calculated on this notional figure, not on global income or assets.
- Low-tax cantons such as Zug and Schwyz deliver combined effective rates of approximately 21–24%, producing annual tax bills well below CHF 100,000 in many cases.
- Five cantons — including Zurich and Basel — have abolished the regime; HNWI applicants must choose from the remaining 21 cantons.
- Henley & Partners ranks Switzerland joint-second globally in its Residence Program Index for 2026, alongside Italy and the UAE.
How the Forfait Fiscal Works in 2026
Switzerland’s lump-sum taxation (Pauschalbesteuerung, or forfait fiscal) was introduced in 1862 and has served as the mechanism through which the country has attracted generations of wealthy foreign nationals. Under the 2026 rules, the taxable base is set at the higher of: seven times the annual rental value (or actual rent) of the Swiss residence; or CHF 435,000 at the federal level. Cantons impose their own minimums — Geneva requires approximately CHF 500,000 and Vaud approximately CHF 450,000, while Zug and Schwyz apply minimums closer to the federal floor.
Tax is then charged on this notional base at the applicable cantonal and municipal rates — meaning a billionaire and a centimillionaire may pay identical Swiss tax if they occupy similar properties. KPMG Switzerland confirms that the total annual tax liability in a low-tax canton typically falls between CHF 60,000 and CHF 80,000 on the federal minimum base, though the precise figure depends on the specific municipality chosen.
Eligibility and Residency Requirements
To qualify for the forfait fiscal, an applicant must: (1) be a non-Swiss national; (2) be relocating to Switzerland for the first time, or returning after an absence of at least ten years; and (3) not engage in any paid employment or business activity on Swiss soil. EU and EFTA citizens enjoy a reduced federal minimum of CHF 400,000. The regime does not impose a formal minimum wealth threshold, but applicants must demonstrate that their worldwide assets and lifestyle are commensurate with the declared tax base — in practice, most cantonal tax authorities require evidence of clear HNWI status.
Swiss residence permits for lump-sum taxpayers are issued under standard B-permit or C-permit frameworks. Family members may be included, and children may attend Swiss schools. After ten years of continuous residence under a B-permit, permanent residency (C-permit) can be obtained — and Swiss citizenship may follow after twelve years total.
What This Means for HNWIs
The forfait fiscal is most advantageous for HNWIs whose passive income — dividends, capital gains from foreign assets, carried interest — would generate substantial tax liabilities in a standard residency jurisdiction. For a HNWI with CHF 10 million in annual passive income, relocation to Zug under the lump-sum regime could reduce Swiss tax exposure to approximately CHF 70,000–80,000 per annum — a fraction of what a comparable income would attract in Germany, France, or the United Kingdom. UK HNWIs exiting following the abolition of the non-dom regime in April 2025 represent a significant share of recent inquiries directed at Swiss lump-sum advisers, according to Swiss private client law firms.
HNWIs should also be aware that Switzerland maintains a broad double tax treaty network (over 100 treaties), but access to treaty benefits under the forfait fiscal is limited: Switzerland only extends treaty protection for income earned in Switzerland. Specialist advice from a Swiss-qualified tax attorney is essential before relying on treaty treatment for foreign-source income. For a broader overview of HNWI tax residency strategies in low and zero-tax jurisdictions, the landscape extends well beyond Switzerland.
Canton Comparison
Selecting the right canton is arguably the single most important decision in a lump-sum relocation. While Zug and Schwyz consistently rank lowest for combined tax rates, other cantons offer distinct lifestyle and infrastructure advantages:
- Zug — Combined effective rate approximately 21–23%; lowest combined rates in Switzerland; home to numerous family office structures; 30 minutes from Zurich Airport.
- Schwyz — Combined effective rate approximately 22–24%; minimal bureaucratic friction; appeals to principals seeking quieter Alpine lifestyles.
- Valais — Lower property prices; internationally recognised ski resorts (Verbier, Zermatt); strong lifestyle appeal.
- Vaud — Minimum base approximately CHF 450,000; Lake Geneva access; proximity to Lausanne; higher combined rates (~30%).
- Geneva — Minimum approximately CHF 500,000; rates ~33–38%; preferred by HNWIs requiring international schools, UN access, and private banking infrastructure.
Risks and Considerations
- Cantonal abolition risk: Five cantons have already abolished the regime via referendum, and political pressure at the federal level resurfaces periodically. HNWIs should monitor legislative developments closely.
- Treaty limitations: Limited access to Switzerland’s double tax treaty network may create double-taxation exposure on foreign-source income if not carefully structured in advance.
- Activity restrictions: Any gainful activity in Switzerland — including board seat compensation for Swiss companies — can disqualify the lump-sum regime. Family office principals should review governance structures before relocating.
- Currency risk: The CHF minimum base is denominated in Swiss francs; USD or EUR-denominated wealth faces fluctuating effective burdens based on exchange rate movements.
The Bottom Line
Switzerland’s forfait fiscal remains one of the world’s most powerful tax residency tools for HNWIs — delivering predictable, capped Swiss tax liability regardless of global wealth levels. For individuals relocating from high-tax European jurisdictions, or those exiting the former UK non-dom regime, Switzerland in 2026 offers a compelling combination of legal certainty, political stability, world-class infrastructure, and fiscal efficiency. The key is early canton selection and specialist structuring before the move.
