A child celebrating their 18th birthday in September, another starting a paid apprenticeship at 17: in both cases, the question of maintaining family allowances arises very concretely. Payments do not automatically stop at adulthood, but the CAF applies a specific age rule, coupled with a condition regarding the child’s income that can cut off the right well before the deadline.
Family allowances and child income: the trap before 20
It is often thought that only the birthday matters. In practice, it is the child’s level of remuneration that causes most early interruptions. The CAF considers a child as “dependent” as long as their net monthly income does not exceed 55% of the net minimum wage. As soon as this threshold is crossed, even at 16 or 17 years old, the child loses their dependent status and family allowances cease for them.
In practical terms, a teenager in an apprenticeship contract or a regular student job can push the entire family out of entitlement. The CAF does not always provide prior warning: it is during the quarterly or annual resource declaration that the anomaly appears, sometimes with an overpayment to be reimbursed.
To better understand the age limit for family allowances according to the CAF, it can be noted that the birthday sets the framework, but the child’s income condition acts as an independent cutoff.
End of family allowances at 20: how the CAF calculates the exact date
Family allowances are paid until the month preceding the child’s 20th birthday. If your child was born on March 15, the last payment concerning them covers the month of February. The month of March is already excluded, even if they have not yet blown out their candles at the time of calculation.
This rule of “the month preceding the 20th birthday” is the same for all beneficiaries, regardless of the child’s professional or educational situation. Whether they are a student, job seeker, or inactive, the date falls the same way.
Families with two children close in age
The most common scenario is that of two children where the elder is approaching 20. When they cross the threshold, the family falls below the threshold of two dependent children and loses all family allowances, since having only one dependent child does not entitle them to this benefit. They find themselves with zero euros overnight, without a transition period.
To mitigate this shock, the CAF pays a flat-rate allowance for one year to families who lose a dependent child and retain at least two other children under 20. This flat-rate allowance is not automatic in all configurations: it targets families with three or more children who see one of them exceed the age limit.
After 20: what CAF benefits remain open
Family allowances stop at 20, but other CAF aids continue beyond that. The family supplement and housing assistance can be maintained up to 21 years in mainland France, provided that the child remains dependent on the household and still meets the income ceiling.
Feedback varies on this point depending on local situations, but here are the main benefits whose age limit exceeds that of family allowances:
- Housing assistance (APL, ALS, ALF): the child attached to the household can be taken into account up to 21 years for the calculation of the amount, provided they do not receive housing assistance personally.
- The family supplement: paid to families with at least three children, it includes children up to 21 years, which can maintain the right even when family allowances have ceased.
- The back-to-school allowance (ARS): it concerns children aged 6 to 18. Its age limit is therefore lower than that of family allowances, creating another cutoff date to watch for.
In summary, the end of family allowances at 20 does not mean the end of all ties with the CAF. But each benefit has its own schedule, and none extend family allowances themselves beyond 20 years.
Resource declaration and maintaining rights: common mistakes
Most payment suspensions observed do not come from an oversight by the CAF, but from a failure to declare on the beneficiary’s side. Two situations recur regularly.
The first concerns the child who starts working without the parents updating their situation on the CAF space. As long as the declaration is not made, allowances continue to be paid, and then the CAF regularizes with sometimes significant overpayments.
The second affects blended families. When a child changes their primary residence (moving to the other parent, leaving for independent housing), the parent who declared the child as dependent must report the change within the month. Without this reporting, rights are calculated on a false basis in both households.
What can be done before the child’s 20th birthday
Checking each year that the child’s remuneration remains below the threshold of 55% of the net minimum wage is the most useful reflex. If the child has a seasonal job, the months of exceeding can be enough to challenge the dependent status for the month concerned.
It is also possible to simulate rights directly on the service-public.fr website to anticipate the loss of the allowance and check if other benefits take over.
The 20-year rule seems simple, but it is the child’s income condition that generates the most unpleasant surprises. Updating the situation of each child on their CAF space as soon as a change occurs remains the most reliable way to avoid overpayments or a sudden interruption of payments.
