Lump Sum Taxation by Canton in Switzerland

Who can apply for lump sum taxation

The regime is open to foreign nationals taking up tax residence in Switzerland for the first time, or returning after an absence of at least ten years, provided they do not exercise gainful employment or self-employment in Switzerland. Swiss nationals do not qualify, and neither does a foreign national who already works in the country, even part time.

Both spouses in a couple must meet the eligibility conditions; if one spouse works in Switzerland, the household generally loses access to the regime and is taxed ordinarily. Eligibility is assessed at the point of arrival and is not automatic: it results from an application to, and an agreement with, the cantonal tax administration.

How the minimum taxable base is calculated

Since the 2016 federal reform of expenditure-based taxation, the taxable base for direct federal tax may not be lower than a multiple of the annual rental value of the taxpayer's Swiss home, or of the rent actually paid, with a statutory minimum floor set in the federal tax legislation. Most cantons that retain the regime apply an equivalent or higher minimum for cantonal and communal tax.

In practice, the tax administration also cross-checks the proposed expenditure base against a control calculation that adds up the taxpayer's actual worldwide living costs known to the authorities, and taxes on whichever base is higher. The final figure is agreed with the canton before residence begins and is generally reviewed at intervals, so it is not a fixed number quoted in advance without that negotiation.

• •Eligibility: no gainful activity in Switzerland, first-time or returning residence
• •Base: multiple of rental value or rent paid, subject to a statutory minimum
• •Comparison: a worldwide expenditure control calculation, taxed on the higher amount
• •Agreement: negotiated with the cantonal tax administration before arrival

Cantons that still offer lump sum taxation, and cantons that abolished it

Following a federal popular vote, cantons remain free to decide whether to offer expenditure-based taxation at cantonal and communal level; the regime otherwise continues to exist for direct federal tax under the tightened 2016 rules. Several cantons have held their own popular votes and abolished the cantonal regime entirely, so residents there are taxed ordinarily on worldwide income and wealth regardless of federal eligibility.

The cantons known to have abolished lump sum taxation at cantonal level are Zurich, Schaffhausen, Appenzell Ausserrhoden, Basel-Landschaft and Basel-Stadt. Most other cantons, including the Lake Geneva region, Bern, Ticino and Graubünden, continue to offer the regime, each applying its own minimum base and administrative practice within the federal floor.

Where families and executives usually get stuck

The regime looks simple on paper but the difficulty is comparative: each canton applies its own minimum multiple, its own control calculation, and its own appetite for negotiation, so the same household can face materially different outcomes depending on where it settles, even between two cantons that both still offer the regime.

A second layer of difficulty comes from timing. Because eligibility depends on not having worked in Switzerland before arrival, and the agreed base is set before residence starts, decisions about the canton, the property, and the household's activities need to be sequenced correctly from the outset rather than adjusted afterwards.

How the application process typically unfolds

A request for lump sum taxation is normally addressed to the cantonal tax administration before or shortly after arrival, supported by information on the household's planned Swiss residence, family situation, and absence of gainful activity in Switzerland. The administration then proposes or discusses a taxable base with the taxpayer's representative.

Because the regime interacts with residence permits, property decisions and, for non-EU/EFTA nationals, immigration procedures, coordinating these strands together, and involving a qualified independent tax adviser for the tax filing itself, is what typically determines whether the process runs smoothly.

• •Confirm the canton's current position on lump sum taxation before committing to a location
• •Assess eligibility for both spouses, not only the main applicant
• •Sequence residence, housing and any Swiss activity before the base is agreed
• •Involve a qualified independent tax adviser for the negotiation and the filing
