The activity bonus is a monthly financial supplement provided to modest workers in France who meet certain income conditions. It replaced the activity component of the active solidarity income (RSA) and the employment bonus on January 1, 2016. The bonus is managed by the Family Allowance Funds (CAF) or the Agricultural Social Mutualism (MSA). Starting April 1, 2026, the bonus received a 0.8% increase, along with a reform of how it is calculated. This reform includes raising the base flat rate and individual bonuses, potentially allowing more households to qualify for the bonus than before. To be eligible, individuals must be of legal age and either employees, civil servants, self-employed workers, or farmers. They must also reside in France in a stable and effective manner, have French nationality, or meet specific conditions for EU citizens or non-EU foreigners. Their income must not exceed a certain threshold. However, temporary workers, those on parental education leave, sabbatical, unpaid leave, or availability (unless receiving income from activity), students, or apprentices earning less than 1,117.26 euros per month (as of April 1, 2026) are not eligible unless they are solely responsible for one or more children. Disabled workers who receive the adult disability allowance (AAH) can also benefit from the activity bonus. If their income is less than 29 times the gross hourly minimum wage, the AAH is fully deducted from the bonus amount. If their income exceeds this threshold, the AAH is considered in the calculation of the bonus. Eligibility is based on various income sources, including professional income or replacement income (like unemployment benefits, sickness benefits, or maternity benefits), free housing, child support, and social benefits such as housing aids or family allowances. However, certain benefits are excluded due to their specific social purpose. For self-employed workers, the bonus is calculated based on the industrial and commercial profits (BIC) or non-commercial profits (BNC) from the last fiscal year, or the revenue from the last quarter if needed. The amount of the activity bonus in 2026 varies based on the household composition and income. A single person without children can receive up to 638.28 euros per month, while a single person with one child can receive up to 957.42 euros. The maximum increases further with additional children. For couples, the maximum is 957.42 euros without children and 1,148.90 euros with one child. These amounts may also change depending on the household structure or in cases of isolation. The activity bonus is calculated using a general formula: Activity bonus = flat rate + 59.85% of professional income + bonuses - resources taken into account - possible housing allowance. Individuals can use the Mesdroitssociaux.gouv.fr website (via FranceConnect) or the CAF website to simulate their potential bonus. The reform also introduced changes to the individual bonus, which depends on the average monthly income over the last three months. The bonus increases with income, up to a maximum of 240.63 euros. The bonus amount can also be increased based on household composition or in cases of isolation. Additional people in the household may lead to a 50% increase for the first person, 30% for the next, and 40% for those beyond the third, depending on the number of children or people under 25. Single parents receive a higher flat rate, which can be granted for 12 months over an 18-month period following events like pregnancy, birth, or separation. The activity bonus is paid on the 5th of the month following the month for which it is due. For example, the bonus for September is paid on October 5. The right to the bonus begins from the month the application is submitted, and the amount remains the same for three months, even if the situation changes. Every quarter, individuals must check their pre-filled declaration online to confirm their household's net social amount. The calculation now uses income from the months M-2 to M-4, not M-1 to M-3. Any changes in professional or family circumstances must be reported promptly through the "report a change" section.
