Le boni pour l'enfant
Before January 2008 tax breaks for children were only claimable on income tax returns. This has now been replaced by a tax bonus ‘le boni pour l'enfant’ which is paid by the Family Allowance Office (Caisse Nationale des Prestations Familiales - CNPF).
The allowance is 922.50 € per year and per child. It's paid on a monthly basis of 76.88€ per child.
There is no need to fill out an application form, as the bonus will automatically be paid to anyone claiming family allowance.
