How do you file taxes in France in 2026?

Most obliged residents file online in the spring campaign after the income year. Deadlines vary by département and filing method; use the date shown in your personal space rather than a forum memory. First-year movers may receive a paper welcome or create the account after payroll starts. Keep bank, employer, and foreign-income documents ready before you open the form.

Tax residence rules on Service-Public decide whether France taxes your worldwide income. A titre de séjour alone does not settle that question. Cross-border workers, partial-year arrivals, and exit years need careful day-count and foyer fiscal analysis, often with a professional for the first declaration.

Open or confirm your impots.gouv.fr access once you have a numéro fiscal. Link bank details for refunds or payments. Update your address when you move; foreigners with longer cards also report address changes on ANEF when required: paperwork after moving.

Housing benefits, mutuelle, and childcare aids sit on other portals but still interact with tax household composition: Apply for housing benefit. Self-employed and company directors add separate social and corporate calendars beyond the plain salarié déclaration.
