Living in France and working in Geneva
Moving · 9 min read · Reviewed
Around a hundred thousand people cross the French border into Geneva to work every weekday. They do it because a two-bedroom flat in Annemasse costs roughly half what the same flat costs in Eaux-Vives, fifteen minutes away on the Léman Express.
That arithmetic is real and it is the single largest lever available to anyone arriving here on a Geneva salary. It also comes attached to a permit, two tax systems, a healthcare election with a three-month deadline, and a border you will cross twice a day for the rest of your time here.
This guide sets out both halves honestly. For a great many people the trade is clearly worth it. For some it clearly is not, and knowing which before you sign a French lease is the point.
What the G permit is
The G permit is the cross-border commuter permit: it lets you live in France (or another neighbouring EU state) and work in Switzerland. Your Swiss employer applies for it, as with a B permit — you cannot self-apply — and it is typically valid for five years on a permanent contract.
The critical wrinkle for a British reader is that the G permit does not, by itself, give you the right to live in France. That is a separate question answered by French immigration law, and since Brexit a British citizen needs a French long-stay visa or residence permit to be there for more than 90 days in any 180. Two permits, two countries, two processes.
This catches people out. Being hired in Geneva does not make you legally resident in Annemasse. Plan both, and plan the French side early, because it is the one nobody tells you about.
A Swiss G permit and a French residence permit are separate things. A British citizen commuting from France needs both. This is the most common and most expensive misunderstanding on this page.
Where the tax actually lands
Geneva is unusual. Under the 1966 France–Switzerland treaty and its 1983 supplement covering the border cantons, cross-border workers employed in Geneva are taxed at source in Switzerland rather than in their country of residence — which is the opposite of the arrangement in most other Swiss cantons.
You will still have French obligations: a French tax declaration, French wealth and property rules, and French social treatment depending on your health insurance election. Being taxed in Switzerland does not make you invisible to the French system.
Since 1 January 2026 Geneva has clarified the remote-working position: a cross-border worker may work from home in France for up to 40% of annual working time without changing where the salary is taxed. Beyond that threshold the treatment changes. If your role is substantially remote, this is a number worth knowing precisely.
The honest ledger
What you gain is straightforward and large: roughly half the rent, French supermarket and restaurant prices, more space, and in the Pays de Gex or above Annemasse, mountains at the end of the road.
What you take on is complexity and time. Two jurisdictions, an annual French declaration, a healthcare election you make once, a car that probably becomes necessary, and a border crossing at rush hour that on the wrong route can add half an hour each way.
Worth weighing before you commit
- Rent and general prices roughly half the Geneva level — the reason anyone does this
- You need a French residence permit as well as a Swiss G permit, and the French one is your responsibility
- Taxed at source in Geneva under the border-canton treaty, but still filing in France
- A one-time choice between Swiss LAMal and French health cover, within three months and hard to reverse
- Remote work from France capped at 40% of annual working time before the tax treatment changes
- Léman Express journeys are quick and reliable; driving across the border at peak is neither
- Swiss schooling is not open to you; your children will be in the French system unless you pay for an international school
Where people actually live
Annemasse is the default: forty thousand people, a real town centre, and the Léman Express straight into Eaux-Vives and Cornavin. It is the best-connected French option by a distance.
Ferney-Voltaire and the Pays de Gex serve CERN, the airport and the international quarter, and hold the largest established anglophone community on the French side — which for a family arriving with no French matters more than the rent difference.
Saint-Julien-en-Genevois suits the Plan-les-Ouates life-sciences cluster, with TPG buses running across the border on Swiss timetables. Thonon-les-Bains is the cheapest of the lot and the furthest, forty to fifty minutes each way along the lake.
Common questions
Can a British citizen live in France and work in Switzerland?
Yes, but it takes two permissions. A Swiss G cross-border permit, applied for by your Swiss employer, plus a French long-stay visa or residence permit, which is your own responsibility as a third-country national in France since Brexit. Neither substitutes for the other.
Where do cross-border workers in Geneva pay tax?
In Switzerland, at source. Geneva is a border canton covered by the 1983 supplement to the France–Switzerland treaty, which reverses the usual rule that cross-border workers are taxed where they live. You will still file a French declaration.
How much cheaper is living in France near Geneva?
Roughly half on rent — a one-bed averaging around CHF 950 equivalent in Annemasse against CHF 2,200 in Eaux-Vives — plus meaningfully lower prices for food, fuel and eating out. Against that, set the cost of a car, the border crossing, and the administrative overhead of two countries.
How much can a cross-border worker work from home?
Up to 40% of annual working time from France, since the position was clarified on 1 January 2026, with the whole salary remaining taxable in Switzerland. Beyond that threshold the tax and social security treatment changes, so check before agreeing a remote pattern.
