Family allowances are a benefit paid by the CAF to families residing in France who bear the effective and permanent responsibility for at least two children under the age of 20. The amount depends on the household’s income and the number of children. Behind this simple rule, several mechanisms deserve to be detailed, particularly the loss of rights that occurs on a child’s twentieth birthday.
To fully understand until what age one can receive family allowances, it is necessary to distinguish the general age limit (20 years) from certain exceptions related to the composition of the household and the type of benefit.
Flat-rate allowance after 20 years: the scheme that families with three children are unaware of
When a family has three children or more and one of them turns 20, the loss of a rank in the calculation of family allowances leads to a significant decrease in the amount paid. To cushion this shock, the CAF provides a transitional flat-rate allowance.
This allowance is paid for one year starting from the month following the child’s twentieth birthday. It applies only to families that continue to have at least two dependent children after this milestone. The child who has just exceeded the age limit must not receive a net monthly income exceeding a ceiling set in reference to the minimum wage (approximately 55% of the net minimum wage).
This scheme remains little known because the official documents from the CAF and Service-public.fr mention the age limit without detailing the transition mechanism. Families with two children do not have this right: when the eldest turns 20, the entire benefit stops, even if the youngest is still a minor and in school.
Residence and income conditions for family allowances
The entitlement is based on two pillars: residing in France and having income below certain thresholds that are revised each year.
Residence in France
For French nationals, one must have their habitual residence in France or stay there for more than nine months per year (consecutive or not). The child must also reside on the territory. If they leave France for more than three months, the allowances are suspended.
- A child studying in a neighboring country while regularly returning to their family is still considered dependent (for example: studying in Germany for an Alsatian family).
- A stay abroad for medical reasons does not suspend rights if the child returns to the household afterwards.
- Foreign nationals must hold a valid residence permit and reside in France in a stable manner.
Income thresholds
Family allowances are adjusted according to the household’s net category income (income received two years before the payment, i.e., income N-2). There are three brackets: full rate, intermediate rate, and reduced rate. The thresholds vary according to the number of dependent children and are revalued each year.
Exceeding the threshold does not completely eliminate the benefit: the amount is simply reduced to the next bracket. This modulation mechanism, implemented a few years ago, replaced the previous system where all families received the same amount regardless of their income.
Age limit for dependent children according to CAF benefits
The concept of a dependent child does not stop with family allowances alone. Depending on the benefit, the age limit varies significantly.
From birth to 3 years, a child is considered dependent without any specific conditions. Between 3 and 16 years, the obligation of school instruction must be respected. From 16 to 20 years, the child remains dependent if their net income before tax withholding does not exceed the threshold set by the CAF.
For housing allowances and family supplements, the limit is raised to 21 years. This distinction creates situations where a family loses its family allowances on the child’s twentieth birthday but temporarily retains other aids.
Loss of rights at 20 years: a budgetary shock to anticipate
The transition at the twentieth birthday concentrates most of the difficulties. For a family with two children, the scenario is the most brutal: the benefit disappears entirely as soon as the eldest crosses this limit.
This is not a simple adjustment. Families that relied on this monthly resource must absorb the loss without a transition period, unlike families with three or more children who benefit from the flat-rate allowance described above.
Several actions can help mitigate the impact:
- Check rights to family supplements if the household has at least three children, one of whom is between 3 and 21 years, subject to income conditions.
- Simulate benefits using the CAF online simulator to identify remaining aids after the loss of family allowances.
- Anticipate the income declaration of the child who has become an adult, as their attachment to the tax household or their detachment modifies the income thresholds taken into account.
The status of a dependent child is based on a criterion of effective and permanent support: food, housing, clothing. An adult child who leaves the family home and supports themselves no longer meets these conditions, which can accelerate the end of rights even before 20 years.
The annual revaluation of the monthly calculation base for family allowances (BMAF) directly determines the amounts paid. Each benefit represents a percentage of this base. Monitoring its evolution allows for precise estimation of future amounts and adapting the family budget accordingly.
