Family allowances are paid by the CAF (or the MSA for the agricultural scheme) to families who bear the effective and permanent responsibility for at least two children residing in France. The general rule sets the end of entitlement at the child’s 20th birthday, but several conditions frame this limit, and a reform that came into effect in March 2026 modifies the threshold for the increase for certain children.
Reform of the family allowance increase: the threshold moves from 14 to 18 years
Common content mentions an increase in family allowances starting at 14 years. This rule remains true, but only for children born before March 1, 2012.
Since March 1, 2026, the increase no longer triggers at 14 years but at 18 years for children born on or after March 1, 2012. In practice, two children from the same family may be subject to different rules depending on their birth date.
This distinction based on birth date makes calculations more complex for large families. To understand the age limit for family allowance and its implications, this new factor must be integrated into the overall calculation of the household’s benefits.
The increase represents a percentage of the monthly calculation base for family allowances (BMAF). Its postponement to 18 years means that some families lose several years of supplement, which weighs on the budgets of households with teenagers.
Family allowance: conditions of effective responsibility and residence in France
The payment of family allowances is based on two pillars: the effective and permanent responsibility for the child and residence in France.
Effective responsibility covers housing, food, and clothing. A child placed with a third party or in an institution may cause the initial parent to lose the benefit of the allowance.
Condition of residence and stay
For a French beneficiary, the usual residence must be in France, or the stay must exceed nine months per year (consecutive or not). The child themselves must reside in France. If they leave the territory for more than three months, the allowances are suspended, except in certain cases:
- The child is studying or receiving medical care in a neighboring country while regularly returning to their family.
- The child is staying abroad to learn a foreign language in a supervised setting.
- The child accompanies a parent on a temporary professional trip outside of France.
Condition related to the child’s remuneration
A child under 20 who works remains dependent as long as their net monthly remuneration does not exceed 55% of the net SMIC. Beyond this threshold, the CAF considers that they are no longer dependent, and the allowances are recalculated accordingly. This remuneration ceiling is rarely highlighted, even though it directly concerns apprentices and young people on student contracts.
Flat-rate allowance after 20 years: a scheme for families with three or more children
The 20-year limit does not always definitively close the right. When a family was receiving family allowances for at least three children and one of them turns 20, a flat-rate allowance may be paid until the month preceding that child’s 21st birthday.
This mechanism prevents a sudden drop in the total amount of benefits. It is conditioned on the fact that the 20-year-old still meets the residence and remuneration ceiling criteria.
For housing assistance and family supplement, the age limit rises to 21 years. These two benefits use a threshold distinct from that of classic family allowances, which sometimes creates confusion among beneficiaries who see one aid stop while another continues.
Amount of family allowances and income ceilings
Family allowances are calculated as a percentage of the BMAF and are adjusted according to the household’s income. The amount varies according to three income brackets:
- Income below the first ceiling: full amount, the highest.
- Income between the first and second ceiling: amount divided by two.
- Income above the second ceiling: amount divided by four.
These ceilings are re-evaluated every year and depend on the number of dependent children. A family with three children has a higher ceiling than a family with two children.
The amount increases with each additional child. The age-related increase (now at 18 years for children born on or after March 1, 2012) is added to the base amount, except for the eldest child in a family of two children, who does not qualify for this increase.
Declaration of resources and role of the CAF
The CAF automatically retrieves the income declared for tax purposes to determine the applicable bracket. No specific steps are necessary for the adjustment, but any change in family situation (birth, departure of a child, separation) must be reported quickly to avoid overpayment.
The right to family allowances generally ends at the child’s 20th birthday, with a possible extension up to 21 years for the flat-rate allowance, family supplement, and housing assistance. The March 2026 reform on the increase adds an additional variable based on each child’s birth date. Regularly checking one’s CAF file remains the most reliable way to ensure that the amounts paid correspond to the household’s actual situation.
