Single base for self-employed social contributions and CSG

Article 18 of the 2024 Social Security Financing Act aligns the base of social contributions paid by self-employed workers with that of the general social contribution (CSG, Article L. 136-3 of the Social Security Code), for contributions due for periods from 1 January 2025 (non-agricultural) and 1 January 2026 (agricultural). Decree 2025-708 of 25 July 2025 sets the implementing rules: charges not deductible from the CSG base, treatment of certain dividends, calculation of provisional payments and adjustment.
