Cross-border · France–Switzerland
Living in France, working in Geneva — taxed properly on both sides.
The 1983 France-Switzerland agreement and the canton-specific accord on Geneva mean cross-border workers pay tax in different places depending on canton, residence, and home-office days. A Geneva fiduciaire who handles this daily will save you from filing twice — and from paying twice.

Local context
What to know in Geneva
- The Geneva accord
- Salaries paid by Geneva employers to French residents are taxed in Geneva, with a fiscal compensation paid back to France — different from the regime covering Vaud or Valais.
- Home-working days
- Up to 40% of working time from home in France is currently tolerated without changing the country of taxation, under the post-Covid agreement.
- Social charges
- Generally Swiss AVS while working in Switzerland, with cross-border health-cover choice (LAMal vs CMU). Choosing wrong is expensive.
- French declaration
- You still file in France — declaring the Swiss income and the Swiss tax paid, with the convention's tax-credit mechanism applied.

FAQ
Common questions
Where is my Geneva salary taxed?
Under the canton-specific accord, salaries paid by Geneva-domiciled employers to French residents are taxed at source in Geneva. France grants a credit for the Swiss tax paid.
Does home-working in France change anything?
Up to 40% home-working time is currently tolerated without changing where you're taxed. Beyond that, a portion of your salary becomes taxable in France — this is where most disputes arise.
Should I take LAMal or CMU?
It depends on age, family size, and chronic conditions. Most Geneva fiduciaires can run the numbers in a single session — the choice locks in for three years.
