In this cross-border worker guide for Switzerland, the essentials fit in one sentence. Becoming a cross-border worker means working in Switzerland while living in France and returning home at least once a week. You need a Swiss contract, a permit G (requested by your employer), and two decisions you cannot afford to get wrong: your tax regime, which depends on the canton, and your health insurance, to be chosen within 3 months between the French CMU and the Swiss LAMal. This choice is irreversible. The application itself follows Swiss conventions, which differ from French habits.
More than 236,000 French residents cross the border every day to work in Switzerland, according to the Federal Statistical Office. If you live in Haute-Savoie, in the Ain, the Doubs or the Territoire de Belfort and you are looking toward Geneva, Lausanne or Neuchâtel, you are one of those asking a question that seems simple on the surface: where to start, and in what order.
Cross-border status is a real advantage, but it comes with precise procedures. Choosing the wrong tax regime or insurance can be costly, sometimes for several years. This cross-border worker guide for Switzerland puts things in order: the permit, the taxes, the insurance, then the application, which remains the first step to clear.
What does it mean to be a cross-border worker in Switzerland?
Cross-border worker status rests on three cumulative conditions. You must hold the nationality of an EU or EFTA country, live in the border zone on the French side, and have an employment contract with an employer based in Switzerland. On top of that comes one simple rule: you return to your main residence in France at least once a week.
It is this weekly-return rule that defines a cross-border worker in the strict sense. As long as you physically cross the border and your home stays in France, you keep your status. The sectors that recruit the most cross-border workers are healthcare, IT, finance, watchmaking and construction, but the logic stays the same whatever your job.
How do you obtain the permit G?
The permit G is the document that authorises a French resident to work in Switzerland as a cross-border worker. Good news: the process does not rest on you. Your future Swiss employer files the request with the relevant cantonal office, normally before your first day of work.
The length of the permit depends on your contract.
| Type of contract | Permit G duration | Renewal |
|---|---|---|
| Permanent contract or contract over one year | 5 years | Every 5 years, on supporting documents |
| Contract of 3 to 12 months | Duration of the contract | Depending on the new contract |
For EU and EFTA nationals, renewal at the end of the 5 years is essentially a formality as long as you are still working in Switzerland. The cantonal authority contacts you a few months before the deadline and asks for the usual supporting documents: contract still active, proof of residence in France, recent salary statement. The permit is tied to your job, so remember to report any change of employer.
Taxes: do you pay in France or in Switzerland?
This is the point that surprises new cross-border workers the most. Your taxation does not depend on a single national rule, but on the canton where you work. Two systems coexist.
| Your canton of work | How you are taxed | In practice |
|---|---|---|
| Geneva | Tax at source | Your employer deducts the tax from your salary each month |
| Vaud, Neuchâtel, Bern, Valais, Solothurn, Jura, Basel-City, Basel-Country | 1983 agreement | Salary paid without tax deducted, tax paid in France the following year |
If you work in Geneva, the tax is withheld directly from your payslip according to a scale linked to your situation. So you receive a salary already net of Swiss tax. Conversely, in the eight cantons covered by the 1983 agreement, you receive almost your full salary, but you have to set aside enough to pay your tax in France the following year. Many cross-border workers in these cantons get caught out in the first year by forgetting to put money aside.
A word on remote work, which has become central. A France-Switzerland agreement allows you to work remotely from France up to 40% of your annual time without changing your tax regime. Beyond that threshold, your tax situation can shift. If you negotiate remote work when you are hired, keep this limit in mind and have it validated by your employer.

Health insurance: CMU or LAMal, how do you choose?
Here is the decision with the heaviest consequences, because it is irreversible. As a cross-border worker, you have the right of option: you choose your health insurance regime between two systems.
- The CMU (French regime). You contribute to French health insurance, based on your income.
- Cross-border LAMal (Swiss regime). You insure with a Swiss provider, with a flat premium per person.
You have 3 months after starting your job to make this choice and communicate it to the relevant cantonal authority. It is a short window, which starts as soon as you take up the role. Crucial point: the choice is final. Once made, you cannot go back as long as you remain a cross-border worker.
What happens if you do nothing? If you fail to choose within the deadline, you are enrolled by default, generally in the Swiss LAMal, with no possibility of changing afterwards. In other words, inaction is itself a decision. Take the time to compare the two based on your family situation and income, because neither option is better in absolute terms.
And where does the application fit in?
Everything above is only triggered by one thing: a Swiss contract. And landing that contract means applying to Swiss standards, which differ from French habits. A CV sent as-is from France often misses the mark.
Three habits make the difference:
- State your cross-border worker status. Indicating that you are targeting a role as a cross-border worker with a permit G reassures the recruiter: they know your work authorisation will not be a problem. This is not an administrative detail, it is a selling point.
- Respect the Swiss format. In French-speaking Switzerland, the professional photo is still widely expected, as is a clear, understated and detailed CV. The conventions are not those of a French CV. We compare them in our article on the Swiss CV versus the French CV.
- Tailor every application to the posting. The Swiss market values precision. A CV and cover letter calibrated to the target role, rather than a generic file, clearly increase your chances at the first screening.
That is exactly what candidat.app does: from your real background, the tool generates a CV and a letter tailored to each Swiss posting, with the right conventions and without inventing anything about you. You prepare the administrative ground, but first you land the interview.
In short
Becoming a cross-border worker follows a logical order. First the Swiss contract, obtained by applying to the country's standards. Then the permit G, which your employer requests for you, valid 5 years for a permanent contract. Then two decisions to lock in quickly: your taxation, which depends on the canton (tax at source in Geneva, taxation in France in the eight cantons of the 1983 agreement), and your health insurance, to be chosen within 3 months between CMU and LAMal, that choice being final. Remote work remains possible up to 40% of the time with no tax impact. Take each step in order, and cross-border status becomes a real lever rather than a headache.
FAQ
Who requests the permit G, me or the employer?
It is your Swiss employer who files the request with the relevant cantonal office, normally before your first day of work. You do not have to carry out this procedure yourself, but you do have to provide the documents requested, such as your contract and proof of residence in France.
Will I pay my taxes in France or in Switzerland?
It depends on the canton where you work. In Geneva, tax is deducted at source each month from your salary. In the eight cantons of the 1983 agreement (Vaud, Neuchâtel, Bern, Valais, Solothurn, Jura, Basel-City, Basel-Country), you are taxed in France the following year and therefore have to set money aside.
Can I change my health insurance later?
No. The right of option between the CMU and the LAMal is exercised only once, within 3 months of starting your job, and the choice is irreversible. If you do not choose within the deadline, you are enrolled by default, generally in the Swiss LAMal.
How many days of remote work from France are allowed?
A France-Switzerland agreement allows you to work remotely up to 40% of your annual time from France without changing your tax regime. Beyond that threshold, your tax situation can change, so validate any remote-work arrangement with your employer.
Do you have to live right next to the border?
You must live in the border zone on the French side and return to your main residence at least once a week. This weekly return is the condition that defines cross-border worker status; your home must stay in France.
