Lump-Sum Taxation in Switzerland: The Forfait Fiscal Explained

Last reviewed on 25 April 2026.

Switzerland's lump-sum taxation regime — known as forfait fiscal in French, Pauschalbesteuerung in German, and "expenditure-based taxation" in formal English — is one of the most-discussed and least-understood features of the Swiss tax system. Done correctly, it is a transparent, negotiated arrangement with cantonal authorities that taxes a wealthy non-working resident on imputed living expenses rather than worldwide income and wealth. Done incorrectly, it is the source of bad advice, miscalibrated expectations, and disputes that can unwind years of planning.

This page explains how the regime actually works: who qualifies, how the assessment base is built, how cantons differ, how it interacts with the country you are leaving, and the practical questions to settle before moving. It is general information and not personal tax advice — anyone considering relocation should engage a Swiss tax specialist and a tax adviser in their country of departure.

What lump-sum taxation is, and what it is not

Lump-sum taxation is an alternative method of computing taxable income and wealth at the cantonal level (and, separately, for federal direct tax). Instead of declaring worldwide income and assets, an eligible taxpayer agrees with the cantonal tax authority on an annual expenditure base — broadly, the cost of the household's lifestyle in Switzerland — and pays tax at ordinary rates on that base.

It is not:

A fixed-fee tax. There is no flat "CHF X per year" payment; the regime computes a base and then applies normal rates.
A way to escape Swiss tax altogether. The minimum bases described below ensure that meaningful tax is paid.
A shield against your home country's continuing taxing rights. You may still be exposed to citizenship-based taxation (notably the U.S.) or to exit-tax regimes from your country of departure.
Available to everyone with money. Eligibility is narrowly defined and is the part most prospective applicants get wrong.

Who qualifies

Eligibility for lump-sum taxation is set out in federal law for direct federal tax and, in parallel, in each canton's tax law. The core conditions are consistent:

The taxpayer is not a Swiss citizen. Swiss nationals cannot use the regime, even if they have lived abroad for decades.
The taxpayer is taking up Swiss tax residence for the first time, or is returning after at least ten years abroad.
The taxpayer does not perform gainful activity in Switzerland. Salary, self-employment, or active business management within Switzerland disqualifies the regime. Passive ownership of foreign businesses is generally compatible, with limits that need careful drafting.
For married couples, both spouses must meet the conditions. A working Swiss spouse breaks the regime for the household.

The "no gainful activity in Switzerland" rule is the most common stumbling block. Hosting board meetings of a foreign company in Switzerland, running an investment vehicle from a Swiss desk, or even significant remote work for a foreign employer can be reclassified as Swiss-source activity by the tax authorities. The line is real and deserves explicit advance ruling from the canton concerned.

How the assessment base is built

The expenditure base is computed using two checks, and the higher of the two applies:

The expenditure check

The taxpayer estimates annual worldwide living expenses — housing, staff, travel, education, vehicles, and so on — for themselves and their dependants. The canton scrutinises this estimate and, in practice, treats Swiss housing costs as the anchor: the imputed rental value of an owned Swiss home, or the actual annual rent for a rented Swiss home, multiplied by a defined factor (commonly seven for federal tax, with cantonal equivalents) is the floor that the expenditure base cannot fall below.

Two practical implications:

The kind of property you live in drives the floor. A modest chalet produces a much lower base than a large lakefront villa.
Cantons keep updating the multipliers and minimums, and have powers to challenge expenditure estimates that look implausibly low for the household profile.

The control calculation (Kontrollrechnung)

Alongside the expenditure check, the taxpayer is required to compute tax on a defined set of Swiss-source income and assets, plus foreign income for which they claim treaty relief in Switzerland. If that figure exceeds the expenditure base, it becomes the base. The control calculation prevents very wealthy taxpayers from sheltering substantial Swiss-source income inside the regime.

Statutory minimums

Federal law sets a minimum expenditure base (currently CHF 421,700 at the federal level, with cantons setting their own minimums, often higher). The taxpayer cannot agree a lower base with the canton. Wealth tax under the regime is computed using a separately defined formula that approximates the income base — cantons differ on how this is implemented.

Cantonal differences are decisive

Lump-sum taxation is a federal regime and a cantonal regime. While the federal element is uniform, cantonal acceptance and parameters differ sharply.

Several cantons have abolished lump-sum taxation at the cantonal level by popular vote (Zurich was the first, in 2009; Schaffhausen, Appenzell Ausserrhoden, Basel-Landschaft and Basel-Stadt followed). In those cantons, federal lump-sum taxation can still apply, but the cantonal portion of tax is computed in the ordinary way.
Other cantons — Vaud, Valais, Geneva, Ticino, the Grisons and several inner-Swiss cantons — continue to operate the regime, with their own minimum bases and multipliers.
Within accepting cantons, the practical bargaining range varies. Some are well-known for being open to negotiation around the floor; others stick more rigidly to published guidelines.

The decision of where to settle is therefore more than a property-shopping exercise. The canton determines whether the regime is available at all, what the minimum looks like, and how disputes are handled.

Worked example: a couple relocating from outside Europe

Consider a hypothetical non-EU couple in their late fifties, with substantial liquid wealth, no Swiss employment plans, and an interest in the Lake Geneva region. After ruling out Geneva for cost reasons, they focus on Vaud.

They identify a property in Canton Vaud with an annual rental value (or actual rent) of CHF 240,000.
The expenditure-multiplier floor for the federal calculation is 7 × CHF 240,000 = CHF 1.68 million. The cantonal floor is set separately and is in a similar range in Vaud.
The federal statutory minimum (CHF 421,700) is below this rental floor, so the rental floor binds.
The control calculation tests Swiss-source income (none material) and foreign treaty-relief income (modest). The control figure is well below the rental floor, so the rental floor remains the base.
Tax is computed at ordinary federal and cantonal rates on a base of CHF 1.68 million. In Vaud, the resulting effective tax bill is significantly higher than the public minimum but materially lower than worldwide-income taxation in many of the couple's possible alternatives.

The number that matters is therefore not the headline minimum but the house. Choosing a smaller property in a cheaper municipality of the same canton would produce a different — and potentially lower — base; the canton's tax administration looks at the totality.

Interaction with the country you are leaving

Swiss lump-sum taxation does not, by itself, disconnect a taxpayer from the country they are leaving. Several issues need to be settled before the move is effective on a net-of-everything basis.

Exit taxes. Several countries levy a deemed-realisation tax on certain assets (typically equities) when residence ends. The Swiss regime does not avoid these — the planning happens before departure.
Continuing source taxation. Income arising in the home country (rental property, partnership distributions, dividends from local companies) remains taxable there at source rates. Swiss tax then applies on the relevant base under treaty rules.
Treaty access while on lump-sum. Some treaties limit benefits for taxpayers under expenditure-based taxation, particularly Italy and France. Swiss tax authorities issue a treaty residence certificate, but a "modified lump-sum" basis (taxing certain treaty-country income in full) may be required to access the treaty rate. This needs to be designed in advance.
Citizenship-based taxation. U.S. citizens remain subject to U.S. federal income tax on worldwide income regardless of Swiss residence. Lump-sum taxation does not change that — it only sets how Switzerland computes its share. The full Swiss/U.S. picture for U.S. citizens is sufficiently complex that it warrants its own specialised advice; see also the account-opening guide on FATCA.

Lump-sum taxation and Swiss banking

The link to Swiss banking is more than incidental. A taxpayer who agrees a substantial expenditure base with a canton needs banking infrastructure that can handle it cleanly: multi-currency accounts for foreign-source income, custody for the assets that generate that income, lending against those assets when liquidity is needed without triggering a sale, and compliance reporting that fits the chosen treaty position.

Practical implications when shortlisting banks:

Private banks with experience of expenditure-based clients tend to have streamlined onboarding for the documentation a canton produces (residence permit, tax-ruling letter, expenditure declaration).
Where the chosen canton has a strong cantonal bank, holding everyday banking there alongside a private-banking relationship elsewhere is common and reduces operational friction.
Source-of-wealth documentation for opening accounts should match the picture presented to the canton. Inconsistencies create pain at both ends.

Common mistakes

Believing the public minimum is the price. The CHF 421,700 federal floor is a backstop, not a target. The rental-multiplier floor almost always binds for households actually wealthy enough to consider the regime.
Choosing canton before testing eligibility. Buying a property in a canton that has abolished the regime locally — without testing federal-only viability — is a classic error.
Underestimating the "no gainful activity" rule. Remote work for a foreign employer, board mandates of operating companies, and active management of a family business can all create issues. Get an advance ruling from the canton.
Forgetting the home-country side. The Swiss design only works if the move is also clean from the country of departure. Exit taxes, residence-tie tests, and continuing source taxation are not Swiss problems — but they can dominate the economics.
Treating the agreement as static. Cantons review expenditure declarations periodically, especially when the household profile changes (new property, new dependants, new staff). The base is not frozen at the original figure.

Decision criteria

Before engaging Swiss tax counsel, it is worth being explicit about the following:

Are you a Swiss national, or have you lived in Switzerland in the last ten years? If yes, the regime is unavailable.
Do you intend to perform any work in Switzerland — including for a foreign employer? If yes, the regime is at risk.
What is your home country, and what does its tax system do when you leave (exit taxes, deemed realisations, citizenship-based taxation)?
Which cantons accept the regime, and which of those produce a tolerable headline base given the property profile you actually want to live in?
How will treaty access work for the most material foreign-source income streams? Is a modified lump-sum compatible with that?
What banking arrangements are needed to operate the household and the investment portfolio cleanly under the chosen base?

Most of these questions are not Swiss-tax questions in isolation — they are joint questions across at least two tax systems and a banking system. That is why expenditure-based residency tends to be set up by a small team: a Swiss tax adviser, a tax adviser in the country of departure, and a Swiss banking relationship that has seen the documentation before. The role of a site like SwissBanks.net is to set the scene and frame the right questions; the answers should always come from professionals who have examined your actual file.
