Switzerland Lump-Sum Taxation: How It Works and Who Actually Gets It
A family with a nine-figure fortune wants one thing more than a low rate: they want the number to be knowable, private, and durable. Their banker suggests a Swiss canton where, instead of declaring the true size of the estate, they would agree a tax bill based on what it costs them to live there. It is not zero. It is a fixed, negotiated figure in a country that has offered exactly this to foreign wealth for over a century.
What the forfait fiscal really is
Switzerland's lump-sum taxation, the forfait fiscal or expenditure-based taxation, replaces the normal system of taxing worldwide income and wealth. Instead, the canton taxes a deemed base tied to your annual living expenses, then applies ordinary federal, cantonal and communal rates to that base. Your actual global income and net worth are not the measuring stick; your cost of living is.
How the base is calculated
The taxable base is the highest of several figures, and cannot fall below statutory floors:
- Seven times the annual rent or rental value of your Swiss home (or three times the cost of board and lodging if you live in a hotel).
- A federal minimum base of 435,000 Swiss francs for 2026.
- A cantonal minimum, which varies widely, from roughly 400,000 to over 1 million Swiss francs depending on the canton.
A control calculation also applies: the tax must be at least what you would pay on your Swiss-source income and certain assets, so the forfait cannot undercut tax on genuinely Swiss income.
| Element | Detail (2026) |
|---|---|
| Basis of tax | Deemed living expenses, not worldwide income |
| Rent multiplier | 7 times annual rent or rental value |
| Federal minimum base | 435,000 Swiss francs |
| Cantonal minimum base | Roughly 400,000 to 1,000,000+ Swiss francs |
| Typical annual tax | Low-to-mid six figures of Swiss francs, negotiated |
| Eligibility | New foreign residents, no Swiss employment |
Who can, and cannot, use it
The forfait is deliberately narrow. It is available to foreign nationals taking up Swiss residence for the first time, or after at least ten years away, who do not carry on any gainful activity in Switzerland. That means:
- Swiss citizens cannot use it, even returning ones.
- Anyone employed or self-employed in Switzerland is excluded. You may run businesses and hold investments abroad, but not earn a Swiss living.
- The canton matters enormously. Several cantons, including Zurich, abolished the regime by popular vote; others, such as Vaud, Valais, Geneva and Ticino, actively welcome it. Where you settle decides both availability and price.
How it compares
Against Italy's 300,000 euro flat tax or Greece's 100,000, the Swiss forfait is usually pricier in absolute terms and cannot be used by anyone who wants to work locally. What Switzerland offers that the Mediterranean regimes do not is its particular blend of stability, discretion, central-European location and a private-banking ecosystem built for exactly this client. It is the choice of families optimising for permanence and privacy rather than for the lowest possible headline number.

Start my free diagnosis →The practical sequence
- Confirm eligibility: foreign national, first Swiss residence (or 10 years away), and no plan to work in Switzerland.
- Choose the canton that offers the regime and negotiates a base you can accept; this is the single biggest lever.
- Agree the ruling with the cantonal authority before you commit, so the annual bill is known in writing.
- Secure a home whose rent or rental value supports the intended base.
- Exit your current tax residency cleanly, settling any exit or departure tax, and file annually to keep the ruling alive.
Frequently asked questions
How does Swiss lump-sum taxation work?
Instead of taxing your worldwide income and wealth, Switzerland taxes a deemed base tied to your annual living expenses. The taxable base cannot be lower than seven times your annual rent or rental value, and cannot fall below a federal minimum, which is set at 435,000 Swiss francs for 2026. Normal federal, cantonal and communal tax rates are then applied to that base.
What is the minimum tax under the Swiss forfait?
There is no single national figure because rates and minimum bases vary by canton. The federal minimum taxable base is 435,000 Swiss francs for 2026, and cantonal minimum bases range from roughly 400,000 to over 1 million Swiss francs. The actual tax bill is negotiated with the canton and commonly lands in the low-to-mid six figures of Swiss francs per year, depending on where you settle.
Who can use Swiss lump-sum taxation?
It is open to foreign nationals taking up Swiss residence for the first time (or after a ten-year absence) who do not carry on any gainful employment in Switzerland. Swiss citizens cannot use it, and anyone working in Switzerland is excluded. Some cantons, including Zurich, have abolished it, so the canton you choose matters.
Is lump-sum taxation the same as paying no tax?
No. You pay real Swiss tax on a substantial deemed base, typically producing a bill in the six figures of Swiss francs a year. The appeal is not zero tax but certainty and privacy: a predictable, negotiated bill that ignores the true size of a large worldwide fortune, in a stable country with strong banking and treaty access.
