Understanding Taxes in Paris (Île-de-France)
Paris salaries are subject to French national income tax calculated on a household quotient basis, plus employee social contributions including CSG (9.2%), CRDS (0.5%), and various insurance contributions. France has no regional income tax variation — the tax system is uniform nationwide. However, Parisian salaries tend to be 15-30% higher than the national average to offset the high cost of living. The French tax year runs January to December, with returns filed the following spring.
