France has an extensive double tax treaty (DTT) network — over 125 countries, with roughly 130 bilateral income tax treaties currently in force. Treaties generally follow the OECD Model Convention, with country-specific variations preserving certain French domestic law provisions. As of 2026, several signed treaties (Belgium, signed 9 Nov 2021; Finland, 4 Apr 2023; Rwanda, 22 Jun 2023; Cyprus, 11 Dec 2023) remain unratified and not yet in force. Treaty coverage typically includes income taxes, corporate taxes, social contribution taxes, and payroll-related taxes, and tie-breaker rules in these treaties can override France's domestic Article 4B tax residency tests.
