About this procedure

Everyone tax-resident in France must file an annual income tax return, even if no tax is due, and even in your first year. The first declaration is often on paper or requires getting a numéro fiscal, after which you file online on impots.gouv.fr. The assistant clarifies whether you are a French tax resident, how to get your tax number, which income to declare and how to complete your return without missing key boxes.

Documents usually involved

  • Numéro fiscal (or first-declaration details)
  • Income statements (payslips, pension, self-employment)
  • Information on any foreign income and accounts
  • Previous year's notice if you have one
  • RIB for any refund or payment

Your done-for-you dossier turns this into a checklist tailored to your exact case.
