Swiss permits B, C and L explained for new residents

Most people who move to Switzerland to live on their own means receive a B residence permit. After five or ten years, depending on nationality and integration, they can obtain a C settlement permit, which is more secure and removes most property restrictions for non-EU nationals. The L is the short-term permit; its time counts towards a C for non-EU nationals, but it is not the usual permit for people settling here.

Key facts (as of September 2026)

• B = residence permit. For non-employed EU/EFTA nationals it is normally valid 5 years.
• C = settlement permit. Non-EU: after 10 years (last 5 continuously on a B), or 5 years if well integrated (art. 34 AIG); UK, US and Canadian nationals can be considered after 5 years.
• EU/EFTA C: after 5 years for most; normally 10 years for 13 more recent member states. The C card is checked every 5 years.
• L = short-term permit; time on it counts towards the non-EU C.
• Stays of up to 90 days in 180 need no registration; otherwise register within 14 days of entry.
• Non-EU nationals with a C are not subject to the Lex Koller; with a B they may buy a main residence (a 2026 proposal would change this).

The three permits at a glance

For people moving here without working, the relevant path is almost always B, then C. Which B you get, and on what conditions, depends on your nationality:

• EU/EFTA nationals receive a B EU/EFTA permit if they have sufficient means and full health and accident insurance. See the B permit without gainful activity.
• Non-EU nationals receive a B through the retiree route (55+) or the important-fiscal-interest route, both with SEM approval. See Swiss residence for financially independent non-EU nationals.

From B to C: how long it takes

For non-EU nationals, the C matters in particular because it takes them outside the Lex Koller restrictions on buying property.

The language requirement for the early C refers to the local national language: French in Geneva or Vaud, German in Zurich or Zug, Italian in Ticino. If an early C matters to you, it is worth factoring into your choice of canton and starting lessons early.

What your permit changes in practice

Buying property

Your permit matters a great deal under the Lex Koller (BewG), the law on property purchases by persons abroad:

Note the word "actual": a permit and commune registration alone are not enough to prove domicile. Indicators include a family household, vehicle registration and full tax liability here.

A reform is under discussion. On 15 April 2026 the Federal Council opened a consultation (which ran until 15 July 2026) proposing that third-country nationals would need a permit even to buy a main residence, and would have to sell within two years if they move away. This is a proposal, not law. We track it in the 2026 Lex Koller reform.

Family members

A non-EU B holder's spouse and unmarried children under 18 may receive a permit if they live together, the housing is suitable, the family does not rely on social assistance or supplementary benefits, and there are local language skills (a language course enrolment is enough at first; children under 18 are exempt from this condition) (art. 44 AIG). EU/EFTA families are covered by the free movement agreement.

Tax

Your permit type does not decide how you are taxed. What matters for lump-sum taxation is your nationality and whether you work in Switzerland:

• A B or C permit is compatible with lump-sum taxation.
• Becoming Swiss ends it, for the whole tax period of naturalisation. Swiss dual nationals are excluded from the start.

If citizenship is a long-term goal, weigh it against the tax regime you use. For how the lump sum works, see Swiss lump-sum taxation.

Keeping your permit

A permit rests on the conditions that justified it, and those conditions have to stay true:

• EU/EFTA non-employed B: the permit can be withdrawn if your financial means or your health and accident insurance fall away.
• Non-EU retiree B: your centre of life must be in Switzerland, or renewal is refused. You also committed not to work, in Switzerland or abroad.
• Non-EU fiscal-interest B: you must have moved your centre of life here and spend most of your time in Switzerland; work is allowed only abroad.

If you are also taxed on a lump sum, the tax authority checks every year that the conditions are still met, and you must report changes without being asked (ESTV Circular 44).

Before any permit: short stays and registration

Stays of up to 90 days within any 180-day period need no registration. If you come to live here without working for more than three months, you register with your commune within 14 days of entry (art. 10 VZAE). EU/EFTA nationals have the same registration duty. From registration, you have three months to take out Swiss basic health insurance (art. 7 para. 1 KVV).

Common misunderstandings

• "Buying a home gives me a B." It does not. Owning property gives no right to a residence permit.
• "The C is automatic after five years." For most non-EU nationals, five years is the early route and depends on integration and language, and the standard is ten. Even where five years is the norm (UK, US, Canada), the C is at the canton's discretion.
• "A B permit is for life once granted." It is renewed or reviewed, and can be withdrawn if the conditions (for example means, insurance or centre of life) are no longer met.

How we help

We help new residents secure the right B permit from the start, keep the conditions met over the years, and plan the move to a C when the time comes. Our residence permit service covers the whole path, or you can begin with the eligibility check.
