Concept
Swiss lump-sum taxation should be described by its legal name: expenditure-based taxation. In German the statutory term is Besteuerung nach dem Aufwand; in French, imposition d'apres la depense. It is a tax regime, not a residence permit, a banking product or a confidentiality wrapper.
The regime is grounded in Article 14 of the Federal Act on Direct Federal Tax and Article 6 of the Federal Act on the Harmonisation of Direct Taxes of Cantons and Communes. The Federal Tax Administration describes it as available in most cantons to individuals without Swiss citizenship who take up tax domicile or residence in Switzerland for the first time, or after at least ten years' absence, and who do not exercise gainful activity in Switzerland.
The regime replaces ordinary income-tax assessment for eligible individuals only within the statutory limits. It does not eliminate the need to prove eligibility, does not override immigration law and does not automatically give full double-tax-treaty access.
Institutions and their function
The Federal Tax Administration (FTA/ESTV) supervises direct federal tax and publishes the Swiss tax-system guidance. It is the federal source for the legal architecture of expenditure-based taxation, direct federal tax, tax residence and the interaction between federal and cantonal tax systems.
Cantonal tax administrations assess the individual file. They decide how expenditure-based taxation is implemented under cantonal law, whether the canton still offers the regime, what cantonal minimums or wealth-tax treatment apply, and what information is required to verify the taxpayer's living expenditure and control calculation.
Cantonal migration authorities and SEM sit outside the tax decision. They decide the residence permit and work-authorisation side. A tax agreement may make the residence file coherent; it is not the document that grants residence.
Eligibility
The federal tax concept is narrow. The taxpayer must be an individual without Swiss citizenship, must take up tax domicile or residence in Switzerland for the first time or after at least ten years' absence, and must not exercise gainful activity in Switzerland. The FTA also states that the taxpayer claiming expenditure-based taxation has to submit the designated tax return and prove that the requirements are met.
The no-gainful-activity condition is the main eligibility risk. For founders, executives and active directors the regime is not compatible with ordinary Swiss work. Management of personal assets is a different question from an active, remunerated role in or from Switzerland. If the file contains board functions, investment-management work, consulting, operating control or remuneration connected to Swiss territory, the activity analysis has to be resolved before the regime can be relied on.
Spouses are not a footnote. Under the federal regime, a household analysis can matter because the expenditure base concerns the taxpayer and family maintained by the taxpayer. Article 14 paragraph 2 DFTA makes this a statutory condition: spouses living in a legally and factually undivided marriage must both meet the eligibility conditions, so a couple in which one spouse is Swiss or works in Switzerland cannot use the regime.
Calculation
Expenditure-based taxation is calculated by reference to the annual expenditure of the taxpayer and the taxpayer's family. The public simplification rent x 12 is wrong. Federal law and FTA guidance describe an expenditure base, statutory minimum tests and a control calculation.
The housing multiple is only one statutory floor. Article 14 DFTA uses the taxpayer's living expenditure and minimum bases tied to the Swiss home or board and lodging; since the 2016 reform the housing floor is seven times the annual rent or imputed rental value, in force for new arrivals from 2016 and for pre-existing lump-sum taxpayers from 2021. The base is the highest of the four tests: actual worldwide living expenditure, the housing multiple, the indexed federal minimum and the canton's own minimum.
The federal minimum is set by Article 14 paragraph 3 letter a DFTA and indexed to the consumer price index; it applies to direct federal tax only. The indexed figures are CHF 429,100 for 2024, CHF 434,700 for 2025 and CHF 435,000 for 2026 (the series is published in Geneva's indexation table). The 2026 amount was written straight into Article 14 paragraph 3 letter a DFTA by article 3 of the FDF Ordinance of 10 September 2025 on the Compensation of the Effects of Cold Progression (Cold Progression Ordinance, VKP, SR 642.119.2; AS 2025 579), in force since 1 January 2026; CHF 400,000 is the 2016 reform figure and no longer appears in the current statutory text.
Cantonal minimums under Article 6 THA are a separate quantity, set canton by canton and applying only to cantonal and communal tax — several cantons also index theirs independently of the federal series, and several add a wealth-tax minimum expressed as a multiple of the expenditure base — Geneva's LIPP (RSG D 3 08) does both. Canton tables therefore date quickly, and a cantonal minimum read as the federal one misstates both: the reliable figure for any canton is the one in its own law for the current tariff year.
The tax is then calculated using ordinary tax rates. Lump-sum taxation is not a flat percentage and not a single Switzerland-wide tax bill. The total burden depends on the canton, commune, church-tax position where relevant, wealth-tax treatment and the control calculation.
Control calculation and treaty relief
The control calculation is the legal answer to the claim that the taxpayer never discloses foreign income or assets. The FTA explains that the tax may not be lower than the ordinary tax on Swiss-source income and wealth components, and on foreign income for which the taxpayer seeks full or partial foreign-tax relief under a double-tax treaty.
That means treaty use can require specific income to be included in the calculation. A person taxed on expenditure may still need to identify Swiss assets, Swiss-source income and foreign-source income for which treaty relief is being claimed. The regime reduces ordinary worldwide-income assessment, but it is not a promise that the tax authority will never examine foreign income, assets, structures or treaty-relevant items.
For seven treaties the price is set out explicitly: FTA Circular No. 44 of 24 July 2018 (section 5.2) records that under the agreements with Belgium, Germany, Italy, Norway, Canada, Austria and the United States a Swiss-resident individual may claim treaty benefits only if all income from that contracting state which is taxable under Swiss law is subject to the direct taxes of the Confederation, the canton and the commune. This is the modified expenditure basis: claiming relief on one line pulls every item of income from that state into the Swiss assessment base, including items nobody asked relief for, and the tax on them is computed at the rate corresponding to total income. The decision is therefore arithmetic — the withholding the treaty gives back, set against the increase in the Swiss bill from the income drawn in. Other treaties are resolved on their own text.
The practical legal conclusion is that expenditure-based taxation can be clean for a passive foreign resident with a documented lifestyle base. It is fragile where the individual wants to work, claim treaty benefits broadly, hold Swiss operating assets, receive Swiss income or present the regime to another state as conclusive tax-residence evidence.
Residence and work boundary
A Swiss lump-sum tax arrangement does not grant a residence permit. EU/EFTA nationals who are not working rely on the free-movement framework and must show sufficient financial means and adequate health and accident insurance. Third-country nationals need a legal basis under the Foreign Nationals and Integration Act, such as retired-person admission, another non-gainful basis or a recognised public-interest derogation.
The tax and migration files must be consistent. If the residence story says the applicant is moving to Switzerland as a non-working person, the tax file cannot simultaneously rely on active Swiss employment. If the business story requires self-employment or executive work in Switzerland, expenditure-based taxation may cease to be the correct tax frame.
Cantonal boundary
The regime is not uniform across Switzerland. The FTA's Swiss tax-system publication states that in most cantons expenditure-based taxation exists, but it also notes cantonal abolition or limitation. Five cantons have abolished it: Zurich (January 2010), Schaffhausen, Appenzell Ausserrhoden, Basel-Stadt and Basel-Landschaft. Bern, Lucerne, St Gallen and Thurgau kept the regime but tightened its rules. The federal tightening took effect for cantonal and communal tax on 1 January 2014 and for direct federal tax on 1 January 2016.
No single table of canton minimums stands in for federal law: the live canton, commune and tax year decide, and a canton-specific figure is reliable only from the canton's own sources. The cantonal minimum is also always a pair of figures rather than one: the minimum expenditure base for cantonal and communal tax, and a minimum wealth-tax base that the canton expresses as a multiple of it — five times in Ticino, ten in Obwalden, twenty in Schwyz and Zug — while Geneva adds 10 per cent to the expenditure base instead of a multiple. The table below covers only cantons whose floor is confirmed in the canton's own statute or by its tax administration; for any other canton the figure for the tariff year is read from that canton's law directly, and the cantons that abolished the regime are listed above.
| Canton | Minimum cantonal expenditure base |
|---|---|
| Bern | CHF 400,000 — art. 16 para. 3 let. a of the cantonal Tax Act (Steuergesetz, BSG 661.11, version of 1 January 2025); the figure is fixed in the statute and not indexed annually. The canton sets no separate wealth-tax minimum base: under para. 6 only Bernese real property is subject to wealth tax |
| Ticino | CHF 400,000 as the base figure of art. 13 para. 3 let. a of the cantonal Tax Act (Legge tributaria, RL 640.100); the canton indexes it to the consumer price index (para. 8), and since 1 January 2025 the minimum stands at CHF 434,700 per the FTA cantonal sheet for Ticino. Minimum wealth-tax base: five times the expenditure base (para. 5) |
| Obwalden | CHF 400,000 — art. 16a paras. 1–4 of the cantonal Tax Act (Steuergesetz, GDB 641.4); not indexed. Minimum wealth-tax base: ten times the expenditure base. The same figure appears in the cantonal tax administration's Merkblatt (in force since 1 March 2022) and in the FTA cantonal sheet |
| Schwyz | CHF 600,000 — § 15a para. 1 let. a of the cantonal Tax Act (Steuergesetz, SRSZ 172.200, consolidated version of 1 February 2026); minimum wealth-tax base twenty times the expenditure base (§ 15a para. 3). Not indexed annually: § 49 StG, as amended on 21 May 2025 and in force since 1 January 2026, recalculates the minimum once every three years. The Merkblatt of the Schwyz cantonal tax administration and the FTA cantonal sheet carry the same figure |
| Geneva | CHF 426,357 for 2026: the base CHF 400,000 of art. 14 para. 3 LIPP is indexed by the canton under art. 67 para. 3 LIPP separately from the federal figure; the 10 per cent uplift on account of wealth tax (para. 4) carries it to CHF 468,993, per the Geneva tax administration's indexation table for 2026 |
| Zug | CHF 500,000 — § 4 of the Ordinance to the Tax Act (Verordnung zum Steuergesetz, BGS 632.11, version of 1 January 2021) on the basis of § 14 StG (BGS 632.1); the floor has applied since 1 January 2016 and the ninth revision of the Tax Act (in force 1 January 2026) left it unchanged. Minimum wealth-tax base: twenty times the expenditure base (§ 14 para. 4 StG), as the FTA cantonal sheet for Zug also records |
| Luzern | CHF 647,100 for the 2026 tax period — § 21 paras. 3–7 of the cantonal Tax Act (Steuergesetz of 22 November 1999); the Regierungsrat adjusts the figure to the consumer price index every year, so it is the highest confirmed cantonal floor in the country. Minimum wealth-tax base: twenty times the assessment basis (FTA cantonal sheet for Luzern) |
| St Gallen | CHF 600,000 — art. 27 para. 2 of the cantonal Tax Act (Steuergesetz of 9 April 1998): the base is seven times the rent or imputed rental value but not less than that figure. Minimum wealth-tax base: twenty times the expenditure base (para. 3), per the FTA cantonal sheet for St Gallen |
| Vaud | CHF 415,000 — art. 15 of the Law on direct cantonal taxes (Loi sur les impôts directs cantonaux of 4 July 2000); the figure already carries a 15 per cent uplift covering wealth tax, and the alternative tests — seven times the rent for a head of household, three times the annual board-and-lodging price otherwise — are likewise increased by 10 per cent (FTA cantonal sheet for Vaud) |
| Valais | CHF 250,000 — art. 11 of the cantonal Tax Act and art. 1 of the ordinance on expenditure-based taxation (OID); the lowest confirmed floor after Jura. Minimum wealth-tax base: at least four times the expenditure amount, that is CHF 1,000,000 at the floor (FTA cantonal sheet for Valais) |
| Neuchâtel | CHF 400,000 — art. 17 para. 1 let. a of the Law on direct cantonal taxes (LCdir), with art. 8 para. 1 of its implementing regulation. Minimum wealth-tax base: five times the base determinative for income tax (art. 17 para. 3), per the FTA cantonal sheet for Neuchâtel |
| Jura | CHF 200,000 — art. 3 of the ordinance of 15 December 2015 on expenditure-based taxation, under art. 54 para. 3 let. a of the cantonal tax law; the lowest confirmed cantonal floor in Switzerland. Wealth tax is computed on at least eight times the income figure retained (art. 54 para. 5), per the FTA cantonal sheet for Jura |
| Nidwalden | CHF 400,000 — § 5 para. 1 of the Tax Ordinance (StV) under art. 16 paras. 3–5 of the cantonal Tax Act; the canton states the wealth side as an absolute figure as well, a minimum taxable wealth of CHF 8,000,000 (§ 5 para. 2) — twenty times the floor (FTA cantonal sheet for Nidwalden) |
| Uri | CHF 400,000 under art. 14 paras. 3–7 of the cantonal Tax Act, indexed in step with the federal figure and therefore CHF 435,000 for the 2026 tax period; the Regulation on expenditure-based taxation of 16 February 2016 sets the procedure. Minimum wealth-tax base: twenty times the expenditure base (art. 14 para. 4), per the FTA cantonal sheet for Uri |
Deviations run upwards from the federal figure, so the floor of the chosen canton is checked in that canton's law for the relevant tariff year, and a cantonal minimum read as the federal one misstates both.
Transparency: what the regime does not switch off
An expenditure base does not take the account holder out of automatic exchange, and since 2026 that statement carries a date. On 26 November 2025 the Federal Council brought the amended Act on the International Automatic Exchange of Information in Tax Matters (AEOIA) and its Ordinance into force with effect from 1 January 2026, so Switzerland now applies the revised Common Reporting Standard. One amendment matters directly to a lump-sum file: associations and foundations, together with their accounts, fall under the standard in their own right — an exemption is available where the conditions are met, but by default a structure held through a Verein or a Stiftung now reads the way an ordinary bank account does.
The crypto half of the same package is deferred. The AEOIA and Ordinance provisions on the exchange of information on crypto-assets do not apply in 2026: Switzerland will implement that exchange no earlier than 1 January 2027, and the decision on the effective date for activating the international legal basis rests with Parliament. The provisions sit in the statute from January 2026; what is deferred is their application. How the crypto exchange itself works is set out separately in crypto-asset reporting.
What the regime does not provide
The label flat tax is shorthand: the legal basis is expenditure-based taxation, and no fixed annual payment replaces disclosure. The taxpayer files the designated return, proves eligibility and remains subject to the statutory control calculation.
A Swiss residence permit does not provide free movement in Europe beyond the Schengen limits. Swiss residence is relevant for Schengen travel, but it is not EU residence and does not create the right to live or work in EU member states.
Family reunification is not an automatic addition to a tax ruling, for adult children and parents least of all. Family residence is an immigration question and depends on the applicant's status, nationality and legal basis for family reunification.
Choosing the canton
Fourteen confirmed floors run from CHF 200,000 in Jura to CHF 647,100 in Luzern — a spread of more than three to one on the same federal statute. The cheapest floor is not the cheapest bill, because the floor only fixes the base: the tax itself is the ordinary cantonal and communal tariff applied to it, and the canton with the lowest floor may carry a heavier tariff than the canton with the highest. Two cantons show the extremes of drafting: Thurgau names no expenditure floor at all and instead guarantees the outcome — income and wealth tax to canton and communes together must reach at least CHF 150,000 a year, with the base built as ten times the rent or four times the board-and-lodging price. Graubünden does the opposite and imports the federal figure, so its cantonal minimum equals CHF 435,000 for 2026.
The second price is the wealth-tax base, and it is the one most often left out of a comparison. Twenty times the expenditure base is the standard — Uri, Nidwalden, Appenzell Innerrhoden, Aargau, Schwyz, Zug, St Gallen and Luzern all use it — while Obwalden takes ten times, Ticino and Neuchâtel five, and Valais four. Geneva uses no multiple and instead adds 10 per cent to the expenditure base; Vaud builds a 15 per cent uplift into the CHF 415,000 figure itself; Bern charges wealth tax on Bernese real property only. Because the multiple attaches to the base rather than to the floor, it scales with the housing test: a base of CHF 2,100,000 in a twenty-times canton produces a deemed taxable wealth of CHF 42,000,000 whatever the family actually owns. That is why the multiple bites hardest on the moderately wealthy — someone with CHF 4 million of assets and a large rented house — and barely registers for a family whose real wealth exceeds the deemed figure.
The floors matter less often than canton tables suggest. The base is the highest of four tests, and in most files the housing multiple wins: seven times an annual rent of CHF 300,000 is CHF 2,100,000, which clears every cantonal minimum in the country. The floor becomes decisive only for the modest end of the regime — a lower rent, a small household — and that is exactly the segment where the choice between Jura at CHF 200,000 and Luzern at CHF 647,100 changes the answer by a factor of three.
Geography of practice diverges from the table of floors. Five cantons abolished the regime after cantonal votes — Zurich with effect from January 2010, then Schaffhausen, Appenzell Ausserrhoden, Basel-Stadt and Basel-Landschaft — and most expenditure-taxed residents live in Vaud, Valais, Geneva, Ticino and Graubünden, that is in the French-speaking and Italian-speaking cantons rather than in the low-tariff cantons of central Switzerland. The last consolidated federal count, on the FDF's page on expenditure-based taxation, is 4,557 people paying CHF 821 million at the end of 2018; the FDF itself directs anyone wanting fresher numbers to the cantons.
Profile against canton
| Profile | What decides the base | Where to look first |
|---|---|---|
| Large rented residence, wealth above the deemed figure | The housing test — seven times the rent — overrides every floor | Tariff and commune, not the floor: the French-speaking cantons where the practice sits |
| Modest household, substantial portfolio | The cantonal floor, and the wealth multiple on top of it | Jura (CHF 200,000, eight times) and Valais (CHF 250,000, four times) |
| Wealth well below twenty times the base | The wealth-tax multiple, which can exceed the real balance sheet | Geneva (plus 10 per cent), Vaud (15 per cent inside the figure), Bern (Bernese real property only) |
| Predictability of the annual bill above all | A guaranteed amount rather than a base | Thurgau: at least CHF 150,000 of income and wealth tax a year |
| Non-EU national needing a residence permit as well | The migration file, decided by the canton separately from the tax agreement | The canton's migration authority: a tax arrangement is not a permit |
Zug against Geneva on the same tenancy
Take a family renting at CHF 5,000 a month. The housing test gives seven times CHF 60,000, or CHF 420,000 — below the indexed federal minimum, so the federal layer is assessed on CHF 435,000. The cantonal layer then follows the canton's own floor: CHF 500,000 in Zug against CHF 426,357 in Geneva, which the 10 per cent wealth uplift carries to CHF 468,993. The Zug base is about 6.6 per cent higher than the Geneva figure — and on the wealth side the gap is of a different order: Zug deems taxable wealth at twenty times the base, CHF 10,000,000, while Geneva takes no multiple at all. For a family with CHF 4 million of assets, Zug's deemed wealth is two and a half times the real balance sheet.
Raise the rent to CHF 25,000 a month and the picture inverts. Seven times CHF 300,000 is CHF 2,100,000, so both floors fall away and the two cantons start from the same base; in Zug the deemed wealth then rises with it, to CHF 42,000,000, while in Geneva the uplift adds 10 per cent and nothing more. The decision is therefore arithmetic in both directions: at a modest rent the floor and the multiple decide, at a large rent the tariff and the commune decide, and in neither case does the canton with the lowest published minimum automatically win.
Q/A
Which canton is cheapest for expenditure-based taxation?
The question has no single answer, because the published minimum is only the floor of the base. Confirmed floors run from CHF 200,000 in Jura and CHF 250,000 in Valais to CHF 600,000 in Schwyz and St Gallen and CHF 647,100 in Luzern for 2026, and the bill is the ordinary cantonal and communal tariff applied to whichever of the four tests produces the highest base. Thurgau does not publish a floor at all and instead guarantees a minimum of CHF 150,000 of income and wealth tax a year.
How does the wealth-tax multiple change the calculation?
It adds a second base that most tables omit. Uri, Nidwalden, Appenzell Innerrhoden, Aargau, Schwyz, Zug, St Gallen and Luzern deem taxable wealth at twenty times the expenditure base, Obwalden at ten times, Ticino and Neuchâtel at five and Valais at four; Geneva adds 10 per cent to the base instead, Vaud carries a 15 per cent uplift inside its CHF 415,000 figure, and Bern taxes only Bernese real property. Because the multiple attaches to the base, a housing test of CHF 2,100,000 produces a deemed wealth of CHF 42,000,000 in a twenty-times canton.
Is the lump-sum regime a pre-agreed fixed annual tax?
No. It is expenditure-based assessment: the tax base follows annual living costs and statutory floors, while ordinary tax rates apply. The canton, commune, housing test and control calculation all affect the result, so a figure in a ruling does not turn the regime into a flat rate.
Can a Swiss citizen or someone working in Switzerland use the regime?
No. The federal regime is for a foreign national who takes Swiss tax residence for the first time, or after at least ten years away, and does not exercise gainful activity in Switzerland. Acquiring Swiss citizenship or starting such work ends eligibility.
Can a lump-sum taxpayer avoid disclosing all foreign income and assets?
There is no blanket exemption. The claimant files the designated return and proves eligibility; the control calculation covers Swiss-source items and foreign income for which treaty relief is claimed. The canton may require the information needed to test those elements and the expenditure base.
Is CHF 435,000 for 2026 the final amount of tax?
No. It is the indexed federal minimum assessment base for direct federal tax, not the bill payable. A canton sets its own base and wealth-tax treatment, while actual living expenditure or seven times the annual rent may produce a higher base than either minimum.
Is the regime available in every canton and does it grant residence?
No. The regime is unavailable in some cantons, and those retaining it apply their own floors and procedures. A tax arrangement also does not grant a residence permit: the migration authority separately tests the legal route, sufficient means, insurance and any restriction on work.
