🇨🇭 Swiss Lump Sum Taxation

Forfait Fiscal — A Unique Swiss Tax Privilege

Switzerland offers a remarkable tax regime to wealthy foreigners taking up Swiss residency. Instead of paying tax on actual worldwide income and assets, qualifying residents pay a fixed annual tax based on a deemed expenditure base — typically resulting in a far lower effective rate than standard Swiss progressive income tax.

💰

Minimum Tax Base (2026)

CHF 435,000

Federal floor. The actual base is the highest of: this amount, 7× annual rent, 3× pension payments, or total worldwide living expenditure.

🗺️

Cantons Offering It

21 of 26

Five cantons have abolished the regime: Zurich, Schaffhausen, Appenzell Ausserrhoden, Basel-Landschaft and Basel-Stadt.

⚖️

Break-Even Point

CHF 800k – 1.2M

Typical worldwide income level at which lump sum tax becomes advantageous over standard Swiss progressive rates. Varies by canton.

📊 The Kontrollrechnung (Control Calculation)

The Swiss authorities run an annual check: if tax calculated on actual Swiss-source income plus income from 7 modified double-tax-treaty states (Germany, Austria, Belgium, Canada, Italy, Norway and the USA) would exceed the lump sum tax, the higher amount becomes payable. This safeguard prevents residents using the forfait purely to claim treaty benefits at near-zero cost.
