A French tax resident is in principle taxable in France on all of their income, wherever it comes from, subject to international tax treaties. A non-resident is in principle taxable in France only on French-source income. The difference between the two statuses is therefore significant, and a person living abroad may need to prove their tax residence abroad, for example to the French tax authorities or to a French bank.
In brief
- French tax residence is determined under Article 4 B of the CGI (home or place of principal stay, main professional activity, centre of economic interests), subject to tax treaties.
- To establish tax residence abroad, the most common documents are a certificate of tax residence issued by the foreign tax authorities, form 5000 certified by those authorities, or a foreign tax assessment.
- Some institutions require a recent document, for example less than three months old, showing the tax identification number.
- A simple utility bill is generally not enough on its own; in the event of a dispute, residence is assessed on the basis of all the facts.

Determining Your Tax Residence
Under Article 4 B of the French General Tax Code (CGI), a person is in principle domiciled in France for tax purposes where they have their home or place of principal stay there, where they carry out their main professional activity there, or where they have the centre of their economic interests there; in principle, one of these criteria is enough. The place of principal stay is generally considered to be in France where the person stays there for more than 183 days in a calendar year. Where a person is also considered resident by another State, the applicable tax treaty, if any, generally makes it possible to settle the question.
Documents to Prove Your Tax Residence Abroad
To prove your tax residence abroad to the French tax authorities or to a French institution (bank, insurer, etc.), the documents generally accepted include the following:
- a tax assessment issued in the country of residence, showing the tax identification number;
- a certificate of tax residence issued by the tax authorities of the country of residence, showing the tax identification number; some institutions require it to be less than three months old;
- form 5000 (certificate of residence) for the current year, certified by the tax authorities of the country of residence;
- a certificate from the local tax authority containing the information required by form 5000.
A simple water or electricity bill is generally not sufficient, on its own, to prove tax residence in a country.
Form 5000 and Tax Treaties
International tax treaties allocate taxing rights between France and the other State, in order to avoid double taxation.
Depending on the treaty, a non-resident receiving French-source income, such as dividends, interest or royalties, may, in some cases, benefit from a reduced rate of withholding tax in France, or even an exemption; only an analysis of the situation by a lawyer can determine whether or not the treaty allows this. Form 5000 (certificate of residence), certified by the tax authorities of the State of residence and accompanied, where applicable, by a form specific to the type of income (form 5001 for dividends, for example), is in principle used to establish residence with the paying institution.
In addition, people who are tax resident abroad and receive French-source income taxable in France must in principle file an income tax return in France.
Other Means of Proof
Where the foreign tax authorities do not complete form 5000, it remains possible in principle to prove residence by any means. More broadly, in the event of a dispute over residence (for example during a tax audit), residence is assessed on the basis of all the facts; the following may in particular be taken into account:
- an employment contract or payslips abroad;
- documents proving enrolment in a school or university abroad;
- bank statements abroad;
- electricity, telephone, water, gas or rent bills abroad.
These items are generally assessed together: none of them is enough on its own to establish tax residence, and each tax treaty may have its own rules.
Proving tax residence abroad can therefore be complex. Each situation deserves to be analysed, ideally with a tax lawyer, in order to identify the relevant supporting documents under French rules and the applicable treaty.
What I see in my cases
The most frequent misconception I come across is that spending fewer than 183 days in France would be enough to no longer be tax resident there. This is inaccurate: the criteria of Article 4 B of the CGI are alternative, and in principle it is enough for the family to live in France, or for the main professional activity to be carried on there, to remain resident there, whatever the number of days; the length of stay only comes into play where there is no home. The most frequent error, in the year of departure, lies in incomplete or poorly handled formalities, with the risk of still being regarded as a French resident: hence the importance of supporting documents gathered from the outset.
FAQ
Who may ask for proof of tax residence abroad?
In practice, proof may be requested by the French tax authorities, for example to apply the rules specific to non-residents or a tax treaty, by a French bank or insurer, to apply the appropriate withholding tax, or by a notary.
What is form no. 5000 for?
It is a certificate of residence stamped by the tax authorities of the State of residence. It may, depending on the case, allow a non-resident to benefit, on certain French-source income (dividends, interest, royalties), from the reduced withholding tax rates provided for by the treaty, usually together with a form specific to the type of income; it is necessary to have one’s situation analysed by a lawyer to find out whether or not these reduced rates apply.
Is a utility bill enough to prove one’s residence?
Generally not. A bill may supplement a file, but tax residence is assessed in the light of all the facts: housing, family, professional activity, economic interests, length of stays.
What happens if the French tax authorities dispute the residence abroad?
They may, depending on the case, treat the person as a French resident and claim tax on all of their income for the years not yet time-barred, with late-payment interest and, where applicable, surcharges. The evidence gathered and the applicable treaty then play a central role; an analysis of the situation by a lawyer is necessary, in particular to find out whether or not the treaty can limit this taxation in France.
For how long can supporting documents be useful?
In principle, the tax authorities may adjust income tax until the end of the third year following the year for which the tax is due; this period may be longer in some cases, for example up to ten years for income linked to an undeclared foreign account (see the article on reassessment time limits). Keeping supporting documents for these periods may therefore be useful.
