Reading your tax treaty: avoiding double taxation

A tax treaty is an agreement between two states allocating the right to tax each category of income and wealth. For an owner domiciled outside France, it determines who taxes rents, sale gains, wealth and estates, and then how potential double taxation disappears. It is read article by article, following a nearly identical layout, which this guide walks you through without jargon. The final questions are prepared with a partner tax adviser, but the method itself takes minutes to learn.

What is a tax treaty, concretely?

Without a treaty, each state could tax the same wealth: France because the property stands on its soil, your country of residence because you are domiciled there. The treaty removes that risk: it is an agreement between two states stating, for each category of income and wealth, which of the two has the right to tax, and how the other neutralises what it may no longer collect. It is layered on top of domestic laws and overrides the domestic rule where more favourable to the taxpayer: this saving principle alone justifies reading it. A great number exist, each signed between France and a partner country, and their content, often similar, presents differences that matter.

A practical point: the treaty creates no tax, it only allocates and neutralises. Nor does it replace returns: each state keeps its own forms, deadlines and penalties. The treaty protects you from double taxation provided you invoke it correctly, that is, you declare on both sides what must be declared, then apply the method the text provides.

How is a treaty structured?

Treaties nearly all follow a common layout, inspired by an international model: scope, definitions, fiscal residence, permanent establishment, then a series of articles devoted to each category of income, and finally the methods for eliminating double taxation, non-discrimination and mutual agreement procedures. For a non-resident owner, four families of articles concentrate the essentials:

• Fiscal residence: it says which side you are attached to when the criteria of both states overlap, with tie-breaker rules provided by the text.
• Income from immovable property: almost always, this article gives the state where the property is located the right to tax the rents it produces.
• Capital gains: the sale of a building generally follows the same logic as rents, with variations between treaties.
• Successions: their treatment varies strongly from one treaty to another, and the dedicated article deserves careful reading.

A reading tip: the articles answer one another. The residence article often refers back to the definitions, the immovable property article specifies what it covers, rents, charges, gains on the sale of the building, and the elimination article lists the articles it neutralises. Reading a treaty means following that thread: start from your question, find the article dealing with it, check its cross-references, and note the elimination method that applies.

Question	Where to look in the treaty	Common trap
Where am I tax resident?	The fiscal residence article and its tie-breaker criteria	Believing you are resident wherever you already pay a global tax
Who taxes my French rents?	The income from immovable property article	Believing French taxation removes the duty to declare elsewhere
Who taxes my sale gain?	The capital gains article	Confusing French taxation with the credit in the country of residence
What happens to my property on death?	The successions article, where it exists	Assuming estate duties follow only the law of the country of residence
How is the tax settled?	The articles on elimination of double taxation	Believing exemption removes every filing duty

Exemption or credit: how does double taxation disappear?

Two broad methods exist. Exemption means your state of residence gives up taxing an income already taxed in France: the income leaves its computation, while sometimes remaining taken into account to set the rate applying to the rest, under a mechanism specific to each country. The credit method means the French income is included in the base of your state of residence, and the tax already paid in France is then deducted, within the limits set by that same state’s rules. A single treaty may combine both methods depending on the categories of income, and the outcome differs markedly according to your country. One essential point in common: even under exemption, returns remain due in both states, because the relief is obtained by declaring, never by staying silent.

Take the most common case, a rent. France taxes the rent under its own rules, regime and scales. Your country of residence then receives that rent in its return: under exemption, the rent leaves the base; under the credit method, it is included and the French tax is credited within its limits. The same reasoning carries over to capital gains and, with more variations, to successions.

Where do you find your treaty, and where do you start?

The text of each treaty is public: the tax administrations of both states publish it, and our country-by-country residence guides select, for each country, the articles that concern an owner of French property. For a first reading, follow this order: the residence article first, to confirm your attachment; then the article of the category occupying you, rents or capital gain; finally the article on elimination of double taxation, to know what your country does with the tax paid in France. Plan the practical side too: if a remainder of tax is still due in France after crediting, its settlement is prepared with an account that can be debited in euros, as explained in our guide on opening a non-resident bank account.

A final point: treaties evolve, through amendment or protocol. Check that the text you are reading is the one in force for the year that concerns you, and keep the version your adviser has validated: that is the one that will serve as reference if the administrations disagree.

Which questions should you put to your partner tax adviser?

A treaty is read all the better when you know what you are looking for. Here are the questions that structure a first exchange with an adviser:

• Is my residence attachment clear within the meaning of the treaty, and what does the text provide in case of dual residence?
• Do my rental incomes fall under the immovable property article, or under another article depending on their nature?
• Does my country apply exemption or the credit method, and with what limits of its own?
• Do my sale gains follow the same article as my rents?
• Are successions and gifts covered, and under which rules?
• Which returns will remain due in each state, even under exemption?

These questions receive answers that vary between treaties: our article on rental income for non-residents shows how they arise concretely for rents. You can also browse the Journal’s Financing & tax category.

Every residence situation is a singular combination of texts and facts: length of stays, family home, sources of income.
