Permit G Switzerland: The Complete Guide for Cross-Border Workers (Frontaliers)

A Permit G (officially: Ausweis G / Livret G) is a Swiss cross-border worker permit issued under the Agreement on the Free Movement of Persons (AFMP) between Switzerland and the EU/EFTA.

Key characteristics:

• It allows you to work in Switzerland while residing in an EU/EFTA state (most commonly France, Germany, or Italy)

• Valid for 5 years if you hold an indefinite employment contract (renewed automatically)

• Valid for the duration of your contract if fixed-term (minimum 3 months to maximum 364 days)

• You must return to your country of residence at least once per week (Article 7 AFMP)

• The permit is canton-specific — it is issued by the canton where your employer is located

• It is not a residence permit for Switzerland — you cannot establish your domicile (domicile fiscal) in Switzerland with a Permit G

To obtain a Permit G, you must meet all of the following conditions:

• Be a citizen of an EU/EFTA member state (or a family member with derivative rights)

• Have a confirmed employment contract with a Swiss employer (or a binding offer)

• Maintain your primary residence in an EU/EFTA country — typically within the border zone, though since June 2007 the geographic restriction has been lifted for EU-25 nationals

• Return to your residence at least once per week

• Not be subject to any transitional restrictions (currently applies only to Croatian nationals until 2026)

UK nationals who held a Permit G before 31 December 2020 retain their rights under the EU-UK Withdrawal Agreement. New UK applicants must follow third-country national rules.

Step 1 — Secure a Swiss job offer: Your employer will initiate the process. The work contract must specify your job title, salary, working hours, and workplace canton.

Step 2 — Employer files the application: Your Swiss employer submits the Permit G application to the cantonal migration office (Office cantonal de la population / Amt für Migration). Required documents typically include:

• Completed application form (canton-specific)

• Copy of your valid EU/EFTA passport or ID card

• Passport-size photos (biometric format)

• Signed employment contract

• Proof of residence in your home country (e.g., attestation de domicile, utility bill)

Step 3 — Receive your permit: Processing takes 2–4 weeks in most cantons. The Permit G is issued as a credit-card-sized biometric card.

Step 4 — Register with local authorities: In France, you should register with your local mairie and, if applicable, with URSSAF or CPAM for social security purposes.

Taxation for Permit G holders depends on your canton of employment and country of residence:

• Geneva: Tax is withheld at source in Switzerland (impôt à la source). You declare and pay taxes in Switzerland only on your Swiss employment income. France grants a tax credit to avoid double taxation (Convention fiscale franco-suisse, Article 17).

• Vaud, Valais, Neuchâtel, Jura, Bern, Bâle-Ville, Bâle-Campagne, Soleure: You are taxed in France on your Swiss salary. Switzerland does not withhold tax. You must declare your Swiss income on your French tax return (formulaire 2047) and benefit from the special frontalier regime.

• Other cantons: Check the specific bilateral agreement — rules vary.

The distinction between "taxation at source" (Geneva model) and "taxation in the country of residence" (other cantons) is crucial and affects your net income significantly.

The AdminLanding Cross-Border Pack (€29) includes a personalised tax simulation for your canton, helping you understand exactly where and how much you will pay. When it's time to file on impots.gouv.fr or register with CPAM, Guide: Démarches en France annotates every field on the official site — in English or French — available as a Chrome extension or Android app on Google Play.

As a Permit G holder residing in France, you face the droit d'option for health insurance:

• LAMal: Swiss compulsory health insurance — fixed premium, coverage in both countries

• CMU/PUMa: French universal coverage — income-based contribution, coverage in France only

You must choose within 3 months of starting work. This choice is irrevocable. See our detailed LAMal vs CMU comparison guide.

For other social security benefits:

• Family allowances: You may be entitled to French CAF allocations AND a Swiss differential complement (allocations familiales différentielles) — the higher benefit applies

• Unemployment: If you lose your Swiss job, you claim unemployment in France (Pôle Emploi), not Switzerland. Your Swiss employer pays Swiss unemployment insurance, but benefits are paid by the country of residence (EU Regulation 883/2004, Article 65)

• Retirement: You accumulate rights in both the Swiss (AVS/LPP) and French systems simultaneously

• Automatic renewal: If you hold an indefinite contract and remain employed, your Permit G renews automatically every 5 years

• Job change: You can change employers freely within Switzerland. Notify the cantonal migration office within 14 days

• Canton change: If your new employer is in a different canton, you need a new Permit G from that canton

• Job loss: If you lose your job, your Permit G remains valid until its expiry date. You have the right to seek new employment in Switzerland during this period

• Telework limits: Since 1 January 2023, cross-border workers can telework up to 49.9% of their working time from home without losing their Swiss social security affiliation (multi-state worker agreement). Exceeding this threshold triggers a change in applicable social security legislation

• Not returning weekly: The weekly return obligation is a legal requirement, not a suggestion. Prolonged absences can invalidate your Permit G status.

• Wrong health insurance choice: Missing the 3-month droit d'option deadline locks you into LAMal automatically. Run the numbers before deciding.

• Ignoring cantonal tax differences: The difference between Geneva (taxed in CH) and Vaud (taxed in FR) can mean thousands of francs per year.

• Forgetting French tax declarations: Even if taxed at source in Geneva, you must still declare your Swiss income in France (formulaire 2047), even though you receive a tax credit.

• Telework without checking limits: Working from home more than 49.9% of the time from France shifts your social security affiliation to France — this has significant cost implications for your employer.

• Not claiming CAF differential: Many frontaliers miss out on the French family allowance complement.
