Moving to Another EU Country

Moving from France to another EU country involves coordinating multiple French administrative systems before departure. Tax residency is determined by the 183-day rule - if you spend 183+ days in France during a tax year, you remain a French tax resident and must file in France; otherwise, you become tax resident in your new country (check double taxation treaties). Declare your departure to the Centre des impôts with your new address and final date in France; you may need to file a final partial-year tax return. For healthcare, the EHIC (European Health Insurance Card) covers temporary stays in EU countries for emergencies and necessary care. For permanent moves, you transition from French Sécurité sociale to the destination country's healthcare system - pensioners receiving French pensions can use form S1 (portable S1) allowing France to cover healthcare costs in the new country. French pension rights are fully portable within the EU thanks to EU coordination regulations 883/2004 - your French pensions (retraite de base and complémentaire) can be paid to any EU country bank account, and contribution periods from different EU countries aggregate for eligibility. Notify pension funds (Assurance Retraite, Agirc-Arrco) of your new address and foreign bank details (IBAN). Practical steps include: canceling or transferring French contracts (EDF, phone, internet - may incur early termination fees), deciding whether to maintain a French bank account (useful for ongoing French income/bills) or close it, handling carte grise by de-registering your vehicle with ANTS if exporting it (you must re-register in the new country within 6 months of residency), and setting up réexpédition (mail forwarding) at La Poste for €30-60 per 6 months to catch important correspondence during transition.
