Switzerland lump-sum taxation: cantonal variation and 2026 floor

The question is no longer whether Switzerland’s lump-sum taxation regime will survive, but how advisors should navigate the widening gap between cantonal offers before the federal floor takes effect in 2026. For the high-net-worth principal considering relocation, the regime remains one of Europe’s most efficient wealth-holding structures — a tax liability based on annual living expenses rather than worldwide income or assets. Yet the landscape has shifted materially since the 2021 federal referendum that mandated a minimum taxable base of CHF 400,000 of deemed expenditure for new arrivals, a rule that comes into force on 1 January 2026. Between now and that date, seven cantons still offer the regime under their own terms, each with distinct calculation methods, minimum thresholds, and political risk profiles. The advisor who understands the granular variation — not the generic concept — can still secure a client a tax bill below CHF 250,000 per year on a multi-million-franc asset base, but only if the canton and the negotiation strategy are chosen with precision. ## The legal architecture of the lump-sum regime Switzerland’s lump-sum taxation, formally known as *forfait fiscal* or taxation based on expenditure, is not a discretionary privilege but a statutory right under article 14 of the Federal Act on Direct Federal Taxation (DBG) and the corresponding cantonal laws. The taxpayer agrees to pay an amount equal to the total federal, cantonal, and communal tax that would be due on their annual living expenses, defined as the cost of maintaining the household including housing, food, transport, and entertainment. The critical feature is that worldwide income and assets are disregarded entirely, provided the taxpayer does not engage in gainful employment in Switzerland. ### The deemed expenditure calculation The taxable base is the higher of two figures: the taxpayer’s actual annual living expenses, or a multiple of the accommodation costs. Most cantons apply a multiplier of five to seven times the annual rental value or the imputed rental value of the taxpayer’s primary residence. For a property with an imputed rental value of CHF 100,000, the minimum deemed expenditure would therefore be between CHF 500,000 and CHF 700,000, depending on the canton. To this base, the canton applies its ordinary progressive tax rates, producing a final tax bill that is often a fraction of what the taxpayer would owe under ordinary taxation on their actual worldwide income. ### The non-employment condition The regime is unavailable to Swiss citizens and to anyone who has held Swiss citizenship within the last ten years. Foreign nationals who take up gainful employment in Switzerland — defined as any activity generating more than CHF 3,000 per year in gross income — are automatically excluded. Passive investment income, capital gains, and dividends from substantial shareholdings are not considered employment and therefore do not disqualify the taxpayer. This makes the regime particularly suited to the retired high-net-worth individual or the family-office principal whose income derives entirely from portfolio returns. ## Cantonal variation: seven distinct offers No two cantons administer the lump-sum regime identically, and the differences in calculation method, minimum threshold, and negotiation flexibility produce materially different outcomes for the taxpayer. As of the publication of this article, the seven cantons that continue to offer the regime are Vaud, Valais, Fribourg, Graubünden, Ticino, Schwyz, and Appenzell Innerrhoden. The remaining cantons, including Zurich, Geneva, and Basel-Stadt, abolished the regime following the 2021 federal vote or have announced they will cease accepting new applications after 31 December 2025. ### Vaud and the statutory minimum Vaud remains the most popular canton for lump-sum taxpayers, with over 400 active cases as of mid-2025. The canton applies a minimum deemed expenditure of CHF 400,000, which aligns with the forthcoming federal floor. The tax calculation uses the taxpayer’s actual living expenses rather than a property multiplier, which can work in the taxpayer’s favour if the imputed rental value is unusually high relative to other costs. The cantonal tax rate on the deemed base is approximately 4.5 percent for the top marginal bracket, producing a total tax bill of roughly CHF 18,000 on the minimum base before communal additions. Communal surcharges vary by municipality and can add 50 to 80 percent, bringing the total to between CHF 27,000 and CHF 32,000 for a single taxpayer on the minimum base. ### Valais and the property multiplier Valais applies a multiplier of seven times the imputed rental value, which is typically lower than in Vaud because property values in the canton are more moderate. A residence with an imputed rental value of CHF 60,000 produces a deemed base of CHF 420,000, slightly above the federal floor. The cantonal tax rate is lower than Vaud’s, at approximately 3.8 percent for the top bracket, and communal surcharges are more modest, often adding 30 to 40 percent. The total tax bill for a single taxpayer on this base would be approximately CHF 22,000 to CHF 25,000. Valais has the additional advantage of a more flexible negotiation culture, where the tax authority may accept a lump-sum agreement based on a written declaration of living expenses without requiring a detailed audit of receipts. ### Ticino and the negotiation model Ticino operates a system that is less formulaic than the other six cantons. The tax authority negotiates a lump-sum amount directly with the taxpayer or their representative, using the statutory minimum of CHF 400,000 as a starting point but adjusting upward based on the taxpayer’s visible lifestyle — property size, vehicle ownership, travel patterns, and children’s school fees. The negotiated figure is then multiplied by the cantonal tax rate of approximately 4.2 percent, plus communal surcharges of 50 to 60 percent. A taxpayer with a substantial villa on Lake Lugano might negotiate a base of CHF 600,000, producing a total tax bill of approximately CHF 40,000 to CHF 45,000. Ticino’s regime is best suited to the taxpayer who prefers a fixed, predictable amount and is willing to engage in a candid discussion with the tax authority. ## The 2026 federal floor and its consequences The federal minimum of CHF 400,000 in deemed expenditure, enacted by the Swiss Federal Council on 17 December 2021 following the 30 May 2021 referendum, will apply to all new lump-sum agreements concluded after 1 January 2026. The floor is indexed to inflation and will be adjusted periodically. For existing taxpayers who entered into an agreement before the effective date, the cantonal rules in force at the time of the agreement continue to apply for the duration of the agreement, which is typically five years with automatic renewal. ### The effect on cantonal competitiveness The federal floor eliminates the advantage of cantons that previously offered lower minimums, such as Appenzell Innerrhoden, which had a de facto minimum of CHF 250,000. After 2026, all seven cantons must apply at least CHF 400,000, which compresses the range of tax outcomes. The differentiating factors shift from the minimum base to the calculation method, the tax rate, and the negotiation culture. Vaud’s actual-expenses model becomes relatively more attractive because it allows the taxpayer to keep the base at the minimum if their living expenses are genuinely modest, while Valais’s property multiplier may produce a higher base if the residence is expensive. ### The grandfathering opportunity The window between now and 31 December 2025 represents a one-time opportunity to lock in the current cantonal rules for a five-year agreement. A taxpayer who concludes an agreement in December 2025 in Appenzell Innerrhoden at a base of CHF 250,000 will pay tax on that base for five years, regardless of the federal floor. The same taxpayer who waits until January 2026 must pay on at least CHF 400,000. The difference in annual tax cost, assuming a total tax rate of 4 percent, is approximately CHF 6,000 per year, or CHF 30,000 over the agreement term. For a taxpayer with a high-value property, the saving is larger because the property multiplier in some cantons would have produced a lower base than the federal floor. ## Worked example: a composite case study Consider a composite client: a 62-year-old British national who has sold a controlling stake in a manufacturing business for GBP 45 million. He holds GBP 30 million in liquid assets across a diversified portfolio of equities, bonds, and private equity funds. He does not intend to work in Switzerland. He is considering two properties — a CHF 3 million apartment in Vaud and a CHF 2.5 million villa in Valais. ### Scenario A: Vaud The imputed rental value of the Vaud apartment is approximately CHF 45,000 per year. Under Vaud’s actual-expenses model, the client declares living expenses of CHF 400,000, which matches the federal floor. The cantonal tax rate of 4.5 percent on this base produces CHF 18,000. With communal surcharges of 70 percent, the total is CHF 30,600. The client’s worldwide income of approximately GBP 1.2 million per year from portfolio returns is entirely disregarded. The effective tax rate on actual income is 2.6 percent. ### Scenario B: Valais The imputed rental value of the Valais villa is CHF 55,000. Under Valais’s seven-times multiplier, the deemed base is CHF 385,000, which is below the federal floor but acceptable under current rules. The cantonal tax rate of 3.8 percent produces CHF 14,630. With communal surcharges of 35 percent, the total is CHF 19,750. The effective tax rate on actual income is 1.6 percent. If the agreement is concluded before 1 January 2026, this rate applies for five years. After 2026, the base would be forced to CHF 400,000, increasing the total tax to approximately CHF 20,520. ### Scenario C: Ticino The client chooses a CHF 4 million villa in Ticino with an imputed rental value of CHF 70,000. The tax authority negotiates a base of CHF 500,000 based on the property and the client’s visible lifestyle. The cantonal rate of 4.2 percent produces CHF 21,000, and communal surcharges of 55 percent bring the total to CHF 32,550. The client has the certainty of a fixed amount for five years, with no audit risk on living expenses. ## Practical planning checklist for advisors The following five steps should be completed before any client signs a lump-sum agreement in Switzerland, ideally before the fourth quarter of 2025 to capture the grandfathering benefit. Secure a written preliminary ruling from the cantonal tax authority before the client acquires a residence or transfers assets into the country. A preliminary ruling confirms the deemed expenditure base, the calculation method, and the duration of the agreement, and it is binding on the authority for the term of the agreement. Compare at least three cantons using a side-by-side model that accounts for the property value, the imputed rental value, the cantonal tax rate, the communal surcharge, and the negotiation culture. The difference between Vaud and Valais for the same client can exceed CHF 10,000 per year. Negotiate the agreement term to five years with automatic renewal rather than a shorter term that would force renegotiation under the federal floor after 2026. The five-year term is standard in most cantons but should be explicitly confirmed in the preliminary ruling. Structure the client’s asset holding to avoid any activity that could be deemed gainful employment. Passive portfolio management through a single-family office that does not engage in trading or advisory services for third parties is safe, but any director’s fee, consulting contract, or board membership exceeding CHF 3,000 per year disqualifies the regime. Prepare a living-expenses declaration that is comprehensive but conservative, listing all household costs including property maintenance, utilities, travel, education, and entertainment. The declaration should be supported by bank statements and invoices for the first year, after which the tax authority typically accepts a sworn declaration without detailed audit. ## Sources - Federal Act on Direct Federal Taxation (DBG), article 14: https://www.fedlex.admin.ch/eli/cc/1990/1999_1999_1999/en - Swiss Federal Council press release on the lump-sum taxation referendum, 17 December 2021: https://www.admin.ch/gov/en/start/documentation/media-releases.msg-id-86232.html - Canton of Vaud, Tax Administration, Lump-sum taxation guidelines: https://www.vd.ch/themes/etat-droit-finances/finances/impots/forfait-fiscal - Canton of Valais, Tax Administration, Expenditure-based taxation: https://www.vs.ch/web/sfi/impot-sur-la-depense - Canton of Ticino, Tax Administration, Imposta sul dispendio: https://www4.ti.ch/dfe/dr/asti/imposte/imposta-sul-dispendio
