Reading your tax treaty: the articles that matter for a property in France, and how double taxation ends

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 dossier gives the state where the property is located the right to tax the income it produces.
• Capital gains: the sale of a building generally follows the same logic as property income, 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.

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 case of a capital gain on sale. France taxes the gain under its own rules, regime and scales. Your country of residence then receives that gain in its return: under exemption, the gain 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 the property’s income and, with more variations, to successions.
