Déclaration de revenus en ligne review
Free French tax filing with prefilled data, calculations, receipts, and mobile support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Déclaration de revenus en ligne is the French government service for filing personal income-tax returns through impots.gouv.fr. It is intended for individuals who need to declare income, deductions, reductions, or tax credits online, including situations involving self-employment, investment income, or rental income. Users authenticate through a personal Finances publiques account, review pre-filled taxpayer information, complete the return, sign it, and receive confirmation and a tax-status notice.
The service is free, with web and mobile access included rather than divided into paid tiers. Its filing workflow covers automatic tax calculation, mileage-expense calculation assistance, and automatic transfer of information between annexes and the main return. Electronic confirmation and a receipt provide a record after submission, while post-submission correction supports changes when a return needs updating. These features make the service suitable for taxpayers who want a single official route for preparing and submitting a French return without a subscription.
Platform choice matters. The website supports the full online filing process, while the official mobile application offers a simplified declaration flow for eligible taxpayers, including some micro-entrepreneur income. Taxpayers with several annexes or certain income types should use the website rather than rely on mobile filing. The service supports cloud and mobile deployment, with email and documentation channels and two-factor authentication. Choose it for official French online filing and a straightforward mobile option; do not choose the mobile flow when the return requires more complex annexes or income details.
