Switzerland taxes you three times — federal, cantonal, communal — and the canton you pick matters more than any planning trick: top combined rates run from about 22% in Zug to about 42% in Geneva. Add an annual wealth tax, subtract capital gains tax on your portfolio. Here are the real 2026 numbers.
Figures verified 9 July 2026Become Swiss tax resident (183+ days, or your habitual home here) and you're taxed on worldwide income and worldwide net wealth. The federal layer is modest — capped at 11.5%. The cantonal and communal layers are where your bill is decided, and they vary enormously: the same CHF 150,000 pension income can face a total bill roughly twice as high in Geneva or Vaud as in Zug or Schwyz. Foreign real estate is exempted but counts for rate-setting. There is no joint US-style standard deduction — but pillar-system deductions, insurance deductions, and married tariffs apply.
| Tax | Who levies it | 2026 reality |
|---|---|---|
| Income tax | Federation + canton + commune | Federal max 11.5%; combined top ~22%–41.6% by canton |
| Wealth tax | Canton + commune | Annual, on net worldwide assets; ~0.1%–1% |
| Capital gains (securities) | — | None for private investors; real-estate gains taxed cantonally |
| Inheritance/gift | Cantons | No federal tax; spouses and (in most cantons) children exempt |
| VAT | Federation | 8.1% / 2.6% reduced / 3.8% lodging |
Americans: the US–Switzerland treaty (signed 1996, in force since December 1997, protocol 2019) plus foreign tax credits prevent most double taxation — but you keep filing US returns, FBAR, and Form 8938 forever, and the treaty's saving clause preserves US taxation of citizens. How US Social Security is taxed between the two countries under Art. 19(4) is genuinely messy and canton-dependent — do not rely on a blog (including ours) for this one. Swiss banks may also be reluctant to take US clients because of FATCA; expect a narrower choice of banks and funds. Canadians: the 1997 treaty (2010 protocol) caps Canadian withholding on periodic pensions at 15%; CPP is payable anywhere, OAS needs 20 years of Canadian residence after 18 to follow you abroad, and the departure tax (deemed disposition) hits when you cease Canadian residence. The totalization agreements (US: since 1980; Canada: since 1995) coordinate social security credits.
The forfait fiscal: who qualifies, the CHF 435k federal minimum, cantonal practice, and the US-citizen catch.
