Quick answer
France has one of the world's largest tax treaty networks, with about 120 bilateral income tax treaties in 2026, most based on the OECD model. They decide which country taxes your salary, business profits, dividends and pensions, and settle dual residence. France usually removes double tax with a credit equal to the French tax, which works like an exemption with progression.

Is this guide for you?
Read on if you…
- live in France and earn salary, fees or investment income from abroad;
- live abroad and still receive French income, such as rent or a pension;
- are, or might be, resident in two countries at once.
Probably not your case if you…
- live and earn everything in France. The treaties will not change your bill;
- deal only with social security. That follows EU rules or separate agreements, not tax treaties.
What does a French tax treaty actually do?
A treaty does not create taxes. It limits them. Each country first applies its own law, then the treaty decides who may tax what, and who must give relief.
Most French treaties follow the OECD model. They cover income tax and, often, corporate tax. A smaller number cover inheritance tax. Since 2019, the Multilateral Instrument has added anti-abuse rules to many of them, including a principal purpose test: treaty benefits are refused if obtaining them was one of the main purposes of a scheme.
Who wins if both countries say you are resident?
France calls you resident under its four domestic tests: household, main stay, main work or centre of economic interests. Our guide to tax residency in France explains each one. Another country may also claim you.
The treaty's tie-breaker then applies, in this order:
- Permanent home. Where you have a home available to you all the time.
- Centre of vital interests. Basically where your life is: partner, kids, main business.
- Habitual abode. Where you spend more time.
- Nationality.
- Mutual agreement between the two tax authorities.
Good news: you only become resident of one country for treaty purposes. The catch: you must still prove it, usually with a tax residence certificate from the other country.
How are the main types of income split?
| Income | Typical treaty rule |
|---|---|
| Salary | Taxed where you physically work; home country only if under 183 days abroad, foreign employer and no local branch cost |
| Self-employed or business profits | Taxed where you live, unless you have a fixed base or permanent establishment elsewhere |
| Company director fees | Often taxed where the company is resident |
| Dividends and interest | Taxed where you live; source country may withhold a capped rate |
| Real estate income and gains | Taxed where the property is |
| Share gains | Usually where you live; some treaties let France tax substantial holdings or property-rich companies |
| Private pensions | Usually where you live |
| Government pensions | Usually by the paying state |
Remote work matters here. If you work from France for a foreign employer, your salary is usually taxable in France from day one. The 183-day exception only helps short trips while you stay resident elsewhere.
How does France avoid double taxation?
French treaties use two methods.
- Tax credit equal to French tax. The most common one for salary, pensions and business profits taxed abroad. The income is included in your French return, then a credit cancels the French tax on it. Result: no French tax, but your other income is taxed at a higher rate. That is the taux effectif rule.
- Tax credit capped at foreign tax. Used mainly for dividends and interest. You get credit for the treaty withholding abroad, and pay the difference in France.
To claim reduced withholding on French dividends as a non-resident, you file form 5000 with your bank or the payer. Our guide to capital gains tax in France shows the domestic rates treaties start from.
What special rules apply to cross-border workers?
France has specific deals with its neighbours for frontaliers (people who cross the border daily or weekly).
- Switzerland. Under the 2023 telework agreement, cross-border workers of Geneva can work up to 40% of their time from home in France without shifting tax. Other cantons follow the 1983 frontier workers agreement with taxation where the worker lives. See our Switzerland tax landscape overview and Switzerland's international tax treaties guide for the Swiss side.
- Luxembourg. Up to 34 days a year of work outside Luxembourg without changing where the salary is taxed.
- Germany, Belgium, Italy, Spain. Frontier worker rules in border zones, with details varying by treaty.
Social security is a separate question. Within the EU, Regulation 883/2004 applies. A framework agreement lets cross-border teleworkers stay insured in the employer's country up to 49% of working time.

Example – Julien, developer living in Annecy
Julien lives in France and works for a Geneva company, earning CHF 110,000. He works three days a week in Geneva and two from home, so 40% telework. Under the France–Switzerland deal for Geneva, his whole salary stays taxed in Switzerland. France includes it in his return, then grants a credit equal to the French tax. He pays no French income tax on it, but his EUR 6,000 of French rent is taxed at a higher effective rate. One extra home day a week would push him over 40% and complicate everything.
Julien's setup works because he counts his home days. Yours needs the same care.

Check my tax setup →Common mistakes (and what they cost)
- Assuming the 183-day rule protects you while living in France → the salary is taxable in France from day one, plus late interest.
- Forgetting to declare treaty-exempt income → you lose the credit and may face a 10% to 40% penalty.
- Not filing form 5000 for French dividends → 12.8% or more withheld instead of the treaty rate.
- Ignoring the principal purpose test → treaty benefits refused on artificial structures.
- Mixing up tax and social security rules → contributions owed in the wrong country, with back payments.
Frequently asked questions
How many tax treaties does France have?
France has around 120 bilateral income tax treaties in force, one of the largest networks in the world. They cover all EU countries, most of the OECD, and many countries in Africa, Asia, the Gulf and the Americas. France also has a smaller number of inheritance tax treaties with countries such as the US, Germany and the UK.
Does the 183-day rule apply in France?
Not in domestic law. France decides residence with four tests, none based on 183 days. The number appears only in treaties, in the salary article: it lets your home country keep taxing short work trips abroad. It does not make you non-resident just because you spend fewer than 183 days in France.
What happens if I am tax resident in France and another country?
The treaty tie-breaker decides. It looks at your permanent home, then your centre of vital interests, then where you habitually stay, then nationality. If all fail, the two tax authorities must agree. You end up resident of one country for treaty purposes, with proof from a residence certificate.
How does France avoid double taxation on foreign salary?
In most treaties, foreign salary taxed abroad is included in your French return, then cancelled by a tax credit equal to the French tax on it. You pay no French income tax on that salary. But it raises the rate applied to your other French-taxed income. This is called exemption with progression.
Can I work from home in France for a Swiss employer?
Yes, within limits. Cross-border workers employed in Geneva can work up to 40% of their time from home in France, and their salary stays taxed in Switzerland. Other cantons follow different rules. Beyond those limits, part of the salary becomes taxable in France. Social security rules are checked separately.
Do treaties change French tax on non-residents' property?
Rarely. French rental income and property gains are taxed in France under almost every treaty, because the property is there. The treaty then makes your country of residence give relief. Check how your new country treats French property income before you move.
