Three key points
- Living outside France does not automatically make you a French tax non-resident.
- French-source income is taxable in France only within the applicable framework, including treaty provisions.
- Tax already withheld does not always remove the filing requirement; the average-rate mechanism may, subject to conditions, reduce tax charged under the progressive scale.
Tax residence is a person’s connection to a country for the application of its tax rules. A tax treaty is an agreement between countries allocating taxing rights and providing for relief from double taxation. This guide explains the French framework for individuals. It does not replace examination of the treaty with your country of residence or your obligations there.
A practical situation
Fictional example. You live and work abroad, where your household is established. You rent out an unfurnished flat in Caen and receive a pension from a French institution. You assume that no French return is needed because your salary is taxed in your country of residence. The rent and pension must nevertheless be examined separately: they do not necessarily fall under the same treaty article or filing arrangements.
1. Are you genuinely a French tax non-resident?
Under French law, several criteria may connect your tax domicile to France: your home or principal place of stay, main professional activity and centre of economic interests. These must be assessed on the facts. An address abroad is not enough if the main part of your family life or interests remains in France.
The often-mentioned “183-day rule” does not resolve every situation. Counting days does not replace examination of your home, activity and economic interests. Tax residence is not simply chosen by entering an address on a form.
If two countries’ domestic rules each regard you as resident, the applicable treaty may resolve the competing claims using its own criteria. Read the treaty in force, any amendments and their effective dates. Moving during the year or a couple living in different countries requires particular care.
Gather evidence explaining your connection: places of residence, activity, travel and foreign tax documents. Owning French property does not, by itself, make you resident, but may create tax obligations.
2. Which French income should be examined?
Once non-residence is established, identify income potentially arising from French sources. French legislation covers various categories, including certain property, professional and investment income, pensions and capital gains. Where the money is paid is not a universal test: a transfer into a French bank account does not, by itself, turn foreign income into French-source income.
For property in France, distinguish unfurnished from furnished letting. The former generally falls under revenus fonciers, the French property-income category; the latter under bénéfices industriels et commerciaux (BIC), the commercial-profits category. The return sections and forms depend on that classification and the applicable regime. Letting through a platform does not remove this distinction.
For salary, where the work is performed is essential, subject to the treaty’s particular rules. A French employer therefore does not mean that all work carried out abroad is automatically taxable in France. International remote working needs to be assessed against the actual locations and periods of work.
For pensions, determine their exact nature: public, private or social security, according to the classifications in the relevant treaty. One retired person may receive several pensions subject to different treatment. The commercial name of a policy or the pension provider’s location alone may not be enough to reach a conclusion.
| Income or transaction | First check | Point requiring attention |
|---|---|---|
| Letting French property | Furnished or unfurnished; direct ownership or company ownership | Appropriate tax category and returns |
| Salary | Location and periods of work | Treaty rules and any withholding |
| Pension | Exact nature of the pension | Relevant treaty article |
| French dividends | Distributing company and recipient | Withholding, treaty and evidence |
| Sale of property or shares | Nature of the asset and sale conditions | Separate regime and possible formalities |
3. How is double taxation avoided?
The treaty may allocate taxation exclusively to one country or allow both to tax with a corrective mechanism. Depending on the treaty, relief may take the form of an exemption or tax credit, meaning an amount offset under the specified conditions. You should not assume that the second country automatically disregards income already taxed in the first.
The analysis must be made income by income. For the rent in the example, examine the property-income article and the residence country’s method of relieving double taxation. For the pension, start again with its category. A correct conclusion for rent cannot be applied to every receipt without further analysis.
Also distinguish the right to tax from the steps needed to apply it. A tax residence certificate or particular form may be required to obtain a treaty rate or seek a refund. Keep evidence of withholding already applied and tax assessments from both countries.
A signed treaty is not necessarily effective: check its application date. Without a treaty, both domestic systems need examination, with no general guarantee that double taxation will be eliminated.
4. How is French tax calculated?
For income subject to the non-resident progressive tax scale, the calculation follows French rules and includes a minimum-tax mechanism. In the general case for income from metropolitan France, minimum rates are 20% on a first portion of net taxable income and 30% above the threshold applicable to the income year. Particular rules apply to income from the French overseas departments.
You may request the average rate (taux moyen) where it is more favourable. This is the rate produced by a French calculation based on the household’s worldwide income, meaning French and foreign income, under the required rules. That information is used to calculate the rate: it does not, by itself, make all your foreign income taxable in France.
Salaries and pensions may be subject to specific non-resident withholding. Dividends and certain capital gains also have their own rules. The minimum-rate mechanism must therefore not be applied indiscriminately to every amount received. Check what has been withheld, what remains reportable and what, if anything, is final withholding.
Finally, income tax and social levies are different matters. For certain property income, membership of a foreign social security system may change the contributions due, depending on the country and applicable conditions. Foreign nationality alone does not create a general exemption. These matters must be documented and addressed separately from the average-rate calculation.
5. How should you prepare a return from abroad?
Start by updating your address and checking access to your French online tax account. Identify the responsible office: the service des impôts des particuliers non-résidents generally manages non-residents’ income tax, while certain matters, particularly those relating to property, remain handled locally. Use your assessment and secure messaging to direct enquiries.
Prepare an annual file: residence evidence, income by category, withholding statements, rent and expenses, foreign tax returns and documents on family circumstances. For the average rate, worldwide income must be established under the relevant French rules with the necessary evidence. A gross figure on a foreign document cannot always be reused directly.
The main return is supplemented by the forms relevant to your position, including property income, furnished letting or withholding on salaries and pensions. Form 2042-NR concerns, in particular, the relevant periods in the year of departure or return; it is not a universal replacement for the ordinary return for everyone living abroad.
Check the filing year: the ordinary 2026 annual return generally concerns 2025 income. Deadlines and forms need checking each year. Keep the filing receipt and supporting file to review the subsequent tax assessment.
Must you file if tax has already been withheld?
It depends on the income and whether the withholding is final. Certain withholding does not complete all obligations. Check the reported sections to avoid both omissions and double counting.
Does having no income tax to pay remove every French obligation?
No. Assets or a transaction in France may create other obligations: property taxes, reporting how a property is occupied, real estate wealth tax (impôt sur la fortune immobilière) or a return linked to a sale, depending on the conditions of each regime.
