Treaty residence: the key to everything
Where an individual is resident in both States, the treaty resolves the question through a series of ranked criteria (Article 4). The order is as follows: first, the permanent home; failing that, the centre of vital interests, that is, the place of the closest personal and economic ties; then habitual abode; and, as a last resort, nationality. This cascade is decisive. A person settled in the UAE but who keeps their family home, the bulk of their income or the seat of their business in France may be reclassified as a French resident within the meaning of the treaty. French domestic law (Article 4 B of the CGI) moreover applies alternative criteria — home or main place of stay, professional activity, centre of economic interests — any one of which is enough to establish domicile in France. The treaty prevails over domestic law, but it only applies where there is a genuine and demonstrable Emirati residence. The firm systematically assesses, upstream, the strength of the connection to the UAE before reasoning about the allocation of taxing rights.
