How to read the tax treaty that actually applies to you
Most cross-border advice consists of quoting a treaty. Almost none of it involves reading the article that decides the case, and the two are not the same activity.
A double tax treaty does not exempt anyone from anything in general. It allocates, category of income by category of income, the right to tax between two states, and then specifies how the state that keeps a residual right eliminates the resulting double charge. Reading one therefore means locating three things in order: the article that decides your residence, the article that covers your particular category of income, and the elimination article that says which method applies. A treaty summary that skips the third has skipped the part that determines the amount.
Residence comes before everything
The residence article first refers back to each state's domestic law, then resolves the case where both claim you through a tie-breaker applied in a fixed sequence: a permanent home available in one state only; the centre of vital interests; habitual abode; nationality; and finally mutual agreement between the administrations. You do not select the criterion that suits you. You work down the list until one of them decides, and everything that follows in the treaty depends on the answer.
Allocation is done category by category
The body of a treaty is a series of articles, each dealing with one type of income: immovable property, business profits, dividends, interest, royalties, capital gains, employment income, directors' fees, pensions, government service, students, and a final article covering everything not otherwise mentioned. Each states which state may tax and on what terms, and several provide for a shared right with a capped rate at source. The practical consequence is that a single household commonly falls under four or five different articles in the same year, and that an answer given for a dividend tells you nothing about a pension.
The two relief methods, and why the difference shows up on the bill
Where both states retain a right, the elimination article specifies one of two mechanisms. Under exemption with progression, the state of residence removes the income from the base but takes it into account in setting the rate applied to the rest, so the income is untaxed but pushes the remainder up the scale. Under the credit method, the state of residence taxes the income and grants a credit for the foreign tax, so the effective burden becomes the higher of the two countries' charges. The same income, the same two countries, and two materially different results depending on which method the treaty specifies. France uses both, depending on the treaty and the category.
The amendments that never appear in the text you downloaded
Two traps close this. First, treaties are amended by protocols, which are published separately and are easy to miss: the text in force is the original as amended, not the original. Second, a large number of treaties have been modified by the multilateral instrument developed through the OECD base erosion work, which changes how covered treaties operate without rewriting their published text. Reading a treaty as it appeared on the day it was signed can therefore give a confidently wrong answer, and the version that matters is the one in force at the date of the facts.
France publishes the treaties it has signed, country by country and with their protocols, through its tax administration. That is the source to work from, and the reading has to be done at the date of the transaction rather than at the date of the advice.
Frequently asked questions
Does a tax treaty mean I only pay tax in one country?
Rarely, and that expectation causes most of the disappointment in this area. A treaty allocates taxing rights category by category, and for several categories it allocates a shared right: the source state may tax, often at a capped rate, and the residence state taxes as well while relieving the double charge. The result is frequently tax in both places with a mechanism that stops it being counted twice, rather than tax in one place only. Which outcome applies depends on the article covering your specific income.
What is the difference between exemption and credit relief?
It is the difference that shows up on the bill. Under exemption with progression, the residence state removes the income from its base but counts it when setting the rate on everything else, so the income escapes tax while pushing the rest up the scale. Under the credit method, the residence state taxes the income fully and allows a credit for the foreign tax, so you end up bearing effectively the higher of the two countries' charges. France uses both, and the treaty specifies which applies to which category.
Where do I find the treaty that applies to me?
The French tax administration publishes the treaties France has signed, country by country, together with their protocols. Work from that source rather than from a secondary summary, and check two things: that you have the original as amended by every protocol, and whether the treaty has been modified by the multilateral instrument produced through the OECD base erosion work, which alters how many treaties operate without changing their published wording. The version that matters is the one in force at the date of the facts.
Can I rely on a treaty article without doing anything?
Usually not. Relief at source often requires a certificate of residence issued by the administration of the state where you are resident, delivered to the payer before payment, and a claim made afterwards is administratively heavier and sometimes time-barred. Where relief comes through a credit rather than at source, the foreign tax has to be evidenced on your return. In both cases the entitlement exists in the treaty and the benefit is obtained through a procedure, which has its own timing.
