The income subject to IR is divided into seven categories: industrial and commercial profits, non-commercial and agricultural profits, land income, salaries and wages, pensions and annuities, movable income, and capital gains. Individuals' total income is taxed if they are resident in France, whether they have French nationality or not. Individuals not living in France are taxed only on their income from French sources. The tax is calculated for each "fiscal household", "i.e." the family unit composed of either a single person, or two partners and their children or other dependents. Whatever the nationality, a person who is a tax resident in France is taxable on their worldwide income. People not living in France are subject to limited tax on their income from French sources only.
