How it reads on exam day
The exam is in French, so this is the question you will see: « Est-il obligatoire de déclarer ses revenus chaque année en France ? ». Learn the English idea above and the French words in the options.
This question comes from the list of the naturalisation version of the exam (PDF relayed by Le Français des affaires, read on 14 October 2026; the Ministry's own page for this list did not answer). The list's wording: “Est-ce obligatoire de déclarer ses impôts chaque année en France ?”.
