Swiss Lump-Sum Taxation (Forfait Fiscal) for Non-Residents: How It Actually Works in 2026

Swiss lump-sum taxation is the regime that lets a wealthy foreigner move to Switzerland and be taxed on their living expenses instead of their global income and wealth. The French call it the forfait fiscal; the Germans, Pauschalbesteuerung; the tax law, spending-based tax. Whatever the name, the appeal is the same. You do not declare your global income or assets at all. Instead you agree a deemed taxable base with a canton, and ordinary tax rates apply to that. For someone with large overseas income, the saving can be enormous.

But the rules are precise and the who qualifies is strict. The regime is also the wrong answer for more people than the glossy guides admit. This is how Swiss lump-sum taxation works in 2026 — the real numbers, the four gates, the control calculation that catches people, and when to walk away even if you qualify.

What Swiss lump-sum taxation actually is

Ordinary Swiss residents are taxed on their global income and net wealth. Swiss lump-sum taxation replaces that with something different. Rather than your real income, the tax is based on a deemed figure built from your living expenses, and ordinary federal, cantonal and local rates are applied to that figure. You never report your actual global income or assets to the Swiss authorities at all. That is the heart of the regime. It appeals to people whose global income dwarfs what they spend living in Switzerland.

The regime is old and well settled, not a loophole. It has existed in Swiss law for over a century. It sits in Article 14 of the Federal Direct Tax Act. At the end of 2024 around 4,700 people were taxed this way, generating more than CHF 900 million in tax a year. Most of them live in Vaud, Valais, Geneva, Ticino and Graubünden. Interest has jumped since the United Kingdom abolished its non-dom regime in April 2025. That sent wealthy residents looking for a stable, lawful option. Switzerland is one of the few that fits.

Who qualifies: the four gates

Eligibility is stricter than most summaries suggest, and all four conditions must be met at once. Miss any one and the regime is simply closed to you.

The fourth gate trips up more couples than any other. Spouses are assessed together, so a single disqualifying factor on either side removes the regime for both. The third gate matters too. The line between forbidden gainful activity and permitted passive wealth management is where applications go wrong. Managing your own investment portfolio is fine. Running a Swiss company, even remotely in some readings, is not. Get a ruling on your specific activities before you rely on the regime.

How the tax base is calculated in 2026

Here is where the real numbers of Swiss lump-sum taxation live. Your deemed taxable base is the highest of four figures, and understanding which one binds is the whole game.

• The federal floor: CHF 435,000 for 2026. This rose from CHF 434,700 under the cold-progression ordinance of 10 September 2025. The base can never fall below this for federal tax.
• Seven times your annual rent or the rental value of your main home. For owners, the same 7× rate applies to the deemed rental value.
• Three times the annual cost of full board and lodging, if you live in a hotel.
• Your actual global living spending, if that is higher than all of the above.

For most wealthy arrivals, the 7× rent figure binds. The homes they rent push the base well above the federal floor. A family renting a Lake Geneva villa at CHF 20,000 a month produces a base of 7 × 240,000. That is CHF 1,680,000 a year. A Zug townhouse at CHF 10,000 a month produces 7 × 120,000, or CHF 840,000. So the house you choose largely sets your tax. That is the single most important planning lever in the regime. It is why canton and property choice come first, not last.

Once the base is fixed, ordinary federal, cantonal and local rates apply to it. In a low-tax canton the rate on the base can sit in the high teens to mid-twenties as a percentage. The lump sum also covers wealth tax. The wealth-tax base is usually a multiple of the deemed income. That can sharply cut the burden for a large global portfolio. You agree the whole deal with the canton in advance, through a tax ruling.

Which cantons still offer it, and the 2026 minimums

Not every canton offers the regime. Five abolished it at cantonal level between 2009 and 2014: Zurich, Schaffhausen, Appenzell Ausserrhoden, Basel-Landschaft and Basel-Stadt. Four of them did so by popular vote. That leaves 21 of 26 cantons offering lump-sum taxation in 2026. In an abolished canton the federal lump sum technically still applies. But cantonal and local taxes make up the bulk of the bill, so the regime is not useful there. So in practice you choose among the cantons that keep it.

Cantons can set their own minimum base above the federal floor. The table shows commonly cited 2026 cantonal practice for the most popular destinations. Treat cantonal figures as a guide. Confirm the current number for your case, because they shift and some are negotiated, not published.

There is a technical quirk worth knowing if you are drawn to central Switzerland. Nidwalden and Obwalden apply a lower rate at cantonal level, 5× rent rather than 7×. But the federal rule still demands 7× for the federal portion. So your cantonal and federal bases differ, and your ruling letter will spell out both. It is the kind of detail that separates a real practitioner from a guide that copies the headline number.

The control calculation that catches people

The lump sum is not a free pass below the deemed base. A control calculation, the Kontrollrechnung, runs alongside it. Your lump-sum tax must be at least as high as the ordinary tax on a defined list of Swiss-source items. That list covers income from Swiss real estate, income from Swiss securities, Swiss-source pensions, and anything for which you claim double-tax-treaty relief. Whichever is higher — the lump sum on the deemed base, or the control calculation — is what you pay.

This matters most when treaty relief is involved, which leads to the single most misunderstood part of the regime. To claim the benefits of certain Swiss tax treaties, you must use a modified form of lump-sum taxation. Switzerland’s treaties with eight countries change this. Germany, France, Italy, Austria, Belgium, Norway, Canada and the United States all require that income from those countries be brought into the control calculation and taxed at ordinary rates, in exchange for treaty protection. If you have real income from any of those eight countries and want the treaty to shield it, you accept modified lump-sum taxation. Most generic guides never mention this, and it can change the entire economics of a move.

When lump-sum taxation is the wrong answer

This is the section the marketing guides leave out, and it is the most valuable. Qualifying for Swiss lump-sum taxation does not mean you should use it. The regime fixes a floor under your tax, based on a deemed base of CHF 435,000 or more. Is your real global income modest next to that base? Then ordinary tax in a low-tax canton can cost you less.

As a rough guide, the lump sum tends to win above roughly CHF 800,000 to CHF 1.2 million of global income, depending on the canton and your rent. Below that band, ordinary taxation in a low-tax canton such as Zug, Nidwalden or Obwalden is often cheaper, even when you qualify for the lump sum cleanly. The regime is built for really large overseas incomes, not merely comfortable ones. Run both calculations before you commit. Choosing the lump sum when ordinary tax would be lighter is a costly and common mistake.

When it does fit, the savings are real. Take an arrival with around CHF 2 million of global income and CHF 15 million of wealth. The lump sum can save several hundred thousand francs a year against ordinary Swiss tax. The exact figure swings widely by canton. That is the prize that makes the regime worth the strict conditions — for the right profile.

Lump-sum taxation, residence and the UK non-dom wave

Swiss lump-sum taxation is also a residence route. The agreed lump-sum ruling supports a standard Swiss residence permit, and a non-EU national usually secures a B permit on this basis, while EU and EFTA nationals rely on free-movement rights. You must make Switzerland your real main home. That means spending the greater part of the year there, with the centre of your life in the country, not just a postal address. Social-security payments also apply, often around CHF 25,000 a year per person.

This is why interest has surged in 2026. When the United Kingdom abolished its non-dom regime in April 2025, thousands of internationally mobile people who had relied on it began looking for a stable, lawful option. Swiss lump-sum taxation offers something rivals do not always match. Italy’s flat tax of EUR 200,000 and Greece’s EUR 100,000 regime are newer and narrower. Switzerland brings a century-old system, deep private banking, and a country whose voters rejected a harsh wealth-tax vote in late 2025. For a displaced non-dom comparing options, the forfait is often the most credible destination of all.

The bottom line on Swiss lump-sum taxation

Swiss lump-sum taxation is one of the most strong legal tax regimes in the world for the right person: a wealthy, non-employed foreigner with large overseas income, taking up Swiss residence for the first time. The 2026 federal floor is CHF 435,000. Twenty-one cantons still offer it, the 7× rent rule usually sets your base, and the control calculation and modified treaty rules decide the fine print.

But it is not for everyone who qualifies. Below roughly CHF 800,000 of income, ordinary tax in a low canton may beat it. So choose the canton and the house first. Model both the lump sum and ordinary tax. Mind the four gates and the spouse rule, and get a cantonal ruling before you move. Done properly, Swiss lump-sum taxation is the cleanest path to Switzerland for serious international wealth.
