The Swiss Lump Sum Taxation and Residency Program lets non-Swiss citizens take up residence in Switzerland and pay a pre-negotiated lump sum tax based on annual living expenses rather than foreign income. To qualify, both spouses must have no Swiss nationality and no tax residency or work in Switzerland in the last 10 years, hold clean police records, and be over 18.
The taxable base is negotiated canton by canton and is generally the highest of CHF 434,700, seven times the annual rent or rental value of the Swiss residence, or the family's worldwide living expenses, with the canton's ordinary rate of roughly 22% to 45% applied. You can include a married spouse and unmarried children under 18 through family reunification. The main applicant and dependents must spend over 6 months a year in the chosen canton. Permits last 5 years for EU, Icelandic, Liechtenstein, and Norwegian nationals and 1 year for others, both renewable. Permanent residency is possible after 5 or 10 years and citizenship after 10. The process takes about 3 to 6 months.
