  • The new French regulation applying to national insurance contributions for managers and shareholders

    French insurance contributions on executive and shareholder remuneration (pay + dividends) have been substantially increased by the National Insurance Funding for 2013 Act, No. 2012-1404, of 17th December 2012. Until 31st December 2012, all dividends were subject to national insurance contributions on unearned income but henceforth, under Article L136-3 of the National Insurance Code, amended by Act No. 2012-1404, certain dividends   are considered as pay received by executives and shareholders and are therefore subject to the national insurance contributions on pay. The Act also abolished the ceiling on health insurance contributions payable by the self-employed and all this means that businesses must rethink the way that they have been structured until now.
