French Prime d'Activité Benefit Application (CAF)
Guidance for applying to the French CAF/MSA Prime d'Activité, a top-up benefit for people with modest professional income.
Who can claim the prime d'activité in 2026?
Any employed or self-employed worker aged at least 18, lawfully and habitually resident in France, whose net earnings from work remain modest. Students and school pupils are excluded unless their earnings exceed the CAF threshold — approximately 78% of the net monthly SMIC (France's statutory minimum wage). Civil servants and public-sector employees are eligible under the same income criteria.

About this form
The prime d'activité (activity bonus) is a monthly income top-up paid by the CAF (Caisse d'Allocations Familiales — France's family benefits authority), or by the MSA for agricultural workers, to employed and self-employed people whose earnings remain modest despite being in work. The entire application is completed online at caf.fr — no paper documents need to be mailed — and the benefit starts on the 1st of the month in which the claim is filed. The amount is calculated on the previous quarter's net income and remains fixed for three months until the next quarterly income declaration (DTR — déclaration trimestrielle de ressources). Any change in earnings only affects the benefit from the following quarter. The bonus can be combined with a salary, the ASS (allocation de solidarité spécifique, a solidarity allowance for people returning to work), and a workplace accident or occupational-disease annuity (rente AT/MP). It cannot be combined with the ASPA (solidarity allowance for older people), the ASI (supplementary invalidity allowance), or the widowhood allowance (Code de la sécurité sociale, art. L. 842-7).
Worked example
Lucie, a part-time sales assistant on a permanent contract (CDI), earns €1,050 net per month. She is single, has no dependants, rents a flat in Lyon for €580/month, and files her claim on 3 March 2026 via caf.fr. The CAF calculates a bonus of approximately €190/month based on her earnings for December 2025 to February 2026 — frozen for the quarter. The file is processed in 5 weeks: the first payment of €190 arrives on 5 May, with entitlement running from 1 March (the catch-up transfer covers both March and April in one payment). In June, Lucie completes her DTR and reports unchanged earnings for March–May; the bonus is maintained at the same amount for the next quarter. Had she missed the DTR, her payments would have been suspended from July until she regularised her account.
How to fill out the form
- Test your eligibility using the anonymous online simulator at caf.fr — no account needed — to get an estimate of your monthly amount in a few minutes.
- Create your espace personnel (personal account) on caf.fr, or log in if you are already a CAF recipient, using your CAF identifier or via France Connect (the French government single sign-on).
- Complete the online application form: enter your net earnings from work for the past 3 months, your monthly rent or mortgage repayment, and your household composition. No supporting documents are required at this stage.
- Submit the application; the CAF reviews the file and confirms its decision by post or via a notification in your espace personnel, normally within 4 to 6 weeks (statutory maximum: 2 months).
- Every 3 months, complete your DTR (déclaration trimestrielle de ressources — quarterly income declaration) via caf.fr to maintain monthly payments and allow the CAF to recalculate the amount based on your actual income.
Good to know
- Quarterly lag: a change in income during the quarter is only reflected in your bonus at the next DTR. If your earnings rise significantly, anticipate this delay to avoid an indu (overpayment that the CAF will reclaim in full).
- Cross-checking: the CAF automatically matches your declarations against data from the DGFiP (tax authority) and Urssaf (social security body). Any omitted income triggers full repayment of sums paid in error and may incur penalties. If you spot a mistake, correct your declaration without delay.
- Apply now — the bonus is never backdated beyond the month of application. The process is entirely free and requires no intermediary. Every month you delay filing is a month of bonus permanently lost.
Frequently asked questions
Who can claim the prime d'activité in 2026?
Any employed or self-employed worker aged at least 18, lawfully and habitually resident in France, whose net earnings from work remain modest. Students and school pupils are excluded unless their earnings exceed the CAF threshold — approximately 78% of the net monthly SMIC (France's statutory minimum wage). Civil servants and public-sector employees are eligible under the same income criteria.
How much is the prime d'activité in 2026?
The amount depends on household composition, net earnings from work, and rent paid. For a single person earning €1,100 net per month, the bonus is approximately €150–200. The reference flat-rate (montant forfaitaire) for a single person with no dependants is approximately €648/month following the April 2026 uprating, which is indexed annually to the reference inflation rate and published in the Journal officiel. The exact figure should be verified on caf.fr. Only the official caf.fr simulator gives a precise amount for your situation.
How do I apply on caf.fr?
Go to caf.fr, create an espace personnel (personal account) or log in if you are already a recipient (allocataire), then click 'Mes aides et services' > 'Prime d'activité'. Enter your net income for the past 3 months, your monthly rent, and your household situation. No supporting documents need to be attached to the application; the CAF may request them later for verification. The claim takes effect from the 1st of the month in which it is submitted.
When is the first payment made?
The bonus is paid on the 5th of each month. Processing a new claim typically takes 4 to 6 weeks (statutory maximum: 2 months). A claim filed at the start of March results in a first payment on 5 April or 5 May depending on processing speed, with a catch-up transfer covering the period from 1 March. Payments continue monthly provided you complete the quarterly income declaration (DTR) within the CAF's deadlines; a missed DTR causes automatic suspension of all payments.
Is there an income ceiling to qualify?
There is no single ceiling: eligibility is determined by a formula combining the reference flat-rate amount, net earnings from work, and other household resources. As a rough guide, a single person with no dependants is generally eligible if net earnings are below approximately €1,900/month; this threshold rises with dependants. The caf.fr simulator gives the exact answer for your specific household situation in a matter of minutes.
Can the bonus be combined with a salary and other benefits?
Yes. The prime d'activité can be combined with a salary, the ASS (allocation de solidarité spécifique — solidarity allowance for job-seekers returning to work), a partial invalidity pension, or a workplace accident/occupational-disease annuity. It cannot be combined with the ASPA (solidarity allowance for older people), the ASI (supplementary invalidity allowance), the widowhood allowance (Code de la sécurité sociale, art. L. 842-7), or the RSA (revenu de solidarité active — France's guaranteed minimum income) when paid with no professional activity. Combination with the AAH (disability allowance) is possible for recipients in employment; this right to cumulate the two benefits predates the October 2023 reform, which solely individualised the AAH calculation by excluding a spouse's income (déconjugalisation, loi n° 2022-1574 du 16 décembre 2022, art. 4).
