Switzerland tax residency: the 30-day rule
Switzerland treats you as a tax resident at 30 days in any rolling 12-month window — but the day count is only the part we can calculate. It is one of Switzerland's tests, not the whole rule (see the others below). Source: Eidgenössische Steuerverwaltung, last reviewed 2025-09-01.
30 days isn't the only route — Switzerland can also treat you as resident on non-day grounds (tax domicile (home + intent to settle), municipal registration / centre of life). See every test below.
Spend 30 days or more in Switzerland across any rolling 12-month window — the count does not reset on 1 January — and residency can attach.

How does Switzerland count days for tax residency?
According to Eidgenössische Steuerverwaltung, you become a tax resident of Switzerland once you spend 30 days or more there in any rolling 12-month window. Crucially, this is a rolling window: it does not reset on 1 January. Any qualifying span that contains enough days can trigger residency, so you have to watch a moving window rather than a fixed year.
30 days with gainful activity
30 days · any rolling 12-month windowSpend 30 days or more in Switzerland across any rolling 12-month window — the count does not reset on 1 January — and residency can attach.
Art. 3 LIFD/DBG: tax residence (sojourn) attaches if you stay in Switzerland 30+ days while carrying on a gainful activity. Cantonal rules apply on top.
90 days without gainful activity
90 days · any rolling 12-month windowSpend 90 days or more in Switzerland across any rolling 12-month window — the count does not reset on 1 January — and residency can attach.
Art. 3 LIFD/DBG: tax residence (sojourn) attaches if you stay 90+ days without any gainful activity (e.g. a long holiday or sabbatical).
What else makes you a tax resident of Switzerland?
The day count is only one route. Switzerland can also make you a tax resident through any one of the following — regardless of how few days you spend there. These don't depend on a day count, so Yuravia can't track them for you; weigh them against your own situation.
Tax domicile (home + intent to settle)
The primary test (Art. 3 LIFD/DBG): you are resident if you take up residence in Switzerland intending to settle — a permanent home plus your centre of life there — independent of any day count.
Municipal registration / centre of life
Registering with the commune and moving your centre of personal and economic life to Switzerland establishes domicile-based residency.
Switzerland at a glance
- Tax year
- 1 January – 31 December (calendar year)
- How days are counted
- Switzerland does not use a fixed 183-day count; residency attaches on a consecutive stay (ignoring short absences) of at least 30 days with gainful activity, or at least 90 days without. PwC's guidance frames these as consecutive periods and does not specify any arrival/departure or part-day rule, so the precise day-by-day treatment is not authoritatively stated.
- What residency means
- A Swiss tax resident is taxed on worldwide income and wealth, levied at federal, cantonal, and municipal levels (real estate and permanent establishments abroad are exempted by allocation). There is no general first-years remittance exception.
- Notable regime
- Lump-sum / expenditure-based taxation (forfait fiscal / Pauschalbesteuerung), for foreign nationals taking up Swiss residence for the first time or after 10+ years' absence and not gainfully employed in Switzerland; tax is based on living expenses with a federal minimum base (CHF 435,000 for 2026, plus cantonal minimums).

Frequently asked questions
How many days can I stay in Switzerland without becoming a tax resident?
According to Eidgenössische Steuerverwaltung, Switzerland treats you as a tax resident at 30 days across any rolling 12-month window (the "30 days with gainful activity"). Staying under that is necessary but not sufficient — a permanent home, family, or your centre of vital interests can make you resident on fewer days.
Is the day count the only way to become a tax resident of Switzerland?
No. Beyond the day count, Switzerland can treat you as resident through tax domicile (home + intent to settle), municipal registration / centre of life — any one of these can apply even if you stay well under 30 days. They don't depend on counting days, so confirm them against your own circumstances.
Does Switzerland have more than one day-count test?
Yes — Switzerland has 2 day-based tests on this page (30 days with gainful activity; 90 days without gainful activity). Any one of them can make you resident, so track against the lowest threshold that could apply to you.
What counts as a day of presence in Switzerland?
In most jurisdictions any day on which you are physically present — including the arrival and departure days — counts as a full day. Treating both as counted is the conservative assumption. Always confirm the exact rule with Eidgenössische Steuerverwaltung.
What is the official source for Switzerland's tax-residency rule?
