The Swiss tax system
Switzerland has 3-level taxation:
- Direct federal tax (IFD): national progressive scale (0–11.5% on income)
- Cantonal tax: varies a lot (5–25% by canton)
- Communal tax: varies by commune (40–100% of cantonal rate)
Typical total marginal rate: 22–42% by canton and income.

- Job relocation: deductible if employer-mandated
- No marriage if modest income gap (cohabitation sometimes better)
For managers and high earners
- Executive LPP plans + maximum annual buybacks
- Planned gifts: progressive transfer (CHF 25,000–50,000/yr exempt in some cantons)
- Real estate company or family structure for large assets
- Choice of applicable law if international assets
For self-employed
- Max pillar 3a (20% of income up to CHF 36,288)
- Provisions and reserves: smooth income variations
- Professional investments deductible
- Moderate salary withdrawal: leave profits in company
- Voluntary LPP setup
For real estate owners
- Choose 20% lump sum or actual for maintenance (actual often better with major work)
- Defer works to high-income years
- Mortgage kept at deductible interest level
- Partial gifts of property to children (asset reduction)
Tax-friendly cantons
Ranking (gross income CHF 200,000, single):
- Zug: 19–22% total rate
- Schwyz: 20–23%
- Nidwalden: 21–24%
- Uri: 22–25%
- Obwalden: 22–26%
Vs:
- Bern: 32–37%
- Geneva: 34–39%
- Basel-City: 32–36%
- Vaud: 31–35%
Changing canton for tax optimisation is possible and common for high earners (but cost of living varies too).
Special cases
Source tax vs ordinary declaration
- B permit with income > CHF 120,000: automatic switch to ordinary
- B permit below threshold: can request TOU (Subsequent Ordinary Taxation) to claim deductions
Couple and tax splitting
- Switzerland: joint taxation (sometimes marriage penalty)
- Partial splitting in Geneva, Vaud (lower joint rate)
- Optimisation: strategic distribution of income and assets
Expatriation and return
- On leaving: exit from taxation, possible capital taxation (LPP, 3a) at preferential rate
- On return: standard taxation resumes
Tips
- Run a simulation annually with cantonal software (often free)
- Professional tax advice: profitable from CHF 80–100k income
- Document everything: invoices, certificates, receipts (keep 10 yrs)
- Plan for life changes: marriage, birth, purchase, moving canton
- Compare cantons if your job allows (remote, self-employed)
