Switzerland’s expenditure-based tax regime, usually called lump-sum taxation, is the oldest surviving arrangement of its kind in Europe. It is also the one most often misdescribed. It is not a flat fee, and it is not available to everyone, everywhere in the country, or to anyone who intends to work.
How the assessment actually works
Under the rules published by the Federal Department of Finance, tax is calculated on the taxpayer’s total annual cost of living, in Switzerland and abroad, for themselves and their dependents. Ordinary tax rates are then applied to that base.
Two floors constrain the result. The law sets minimum values for the assessment base, and a control calculation ensures the tax is never lower than it would be on specified Swiss-source income and wealth at normal rates. The regime substitutes a different measure of ability to pay. It does not substitute a token one.
- Eligibility: foreign nationals taking Swiss tax domicile for the first time, or after at least ten years abroad
- Employment: no gainful activity in Switzerland
- Base: worldwide annual living expenditure, not income
- Floors: statutory minimum base plus a Swiss-source control calculation
- Uptake: fewer than 0.1 percent of Swiss taxpayers

Rich & Richer
The part most summaries omit
Lump-sum taxation is administered cantonally and it has been voted away. Zurich’s electorate abolished it in a 2009 popular vote, effective January 2010, and Schaffhausen, Appenzell Ausserrhoden, Basel Landschaft and Basel Stadt followed. A national abolition initiative was subsequently put to voters and rejected, which is why the regime survives federally while being unavailable in several cantons.
For anyone weighing it, that is the material risk and it is not a tax risk. It is a political one, decided by referendum on a timetable no adviser controls.
The same pattern, across the continent
Europe has spent two years repricing residence rather than abolishing it. Britain replaced the non-dom regime with a four-year window, Spain repealed its investor residence permit outright, and Switzerland’s oldest arrangement survives at federal level while shrinking at cantonal level. A residence plan resting on one jurisdiction’s current statute is resting on the least durable thing in the structure.
