Benin Social Contributions Guide 2026

Benin's social security system is administered by the Caisse Nationale de Sécurité Sociale (CNSS). Contributions are mandatory for all employees: 5.4% employee share and 17.4% employer share of gross salary, capped at a monthly ceiling. The system provides pension, disability, survivor benefits, and occupational health insurance.

Overview — CNSS

The Caisse Nationale de Sécurité Sociale (CNSS) manages Benin's social security system. All employers must register with CNSS and contribute on behalf of their employees. Contributions are calculated as a percentage of gross salary, subject to a monthly earnings ceiling (plafond). The ceiling is periodically adjusted by CNSS. Self-employed individuals may voluntarily contribute to CNSS for pension coverage under specific schemes.

Contribution Rates

  • Employee contribution — 5.4% of gross salary (capped)
  • Employer contribution — 17.4% of gross salary (capped)
  • Total — 22.8% of gross salary

The monthly contribution ceiling (plafond) is approximately XOF 1,200,000 for 2026. Earnings above this ceiling are not subject to CNSS contributions. The employer is responsible for remitting both contributions to CNSS monthly, by the 15th of the following month.

Employer Obligations

Employers must: (1) register with CNSS within 8 days of hiring the first employee, (2) declare all employees and their salaries, (3) calculate and deduct the employee share (5.4%) from salary, (4) add the employer share (17.4%), and (5) remit the total to CNSS monthly. Employers must also file annual salary declarations and maintain individual employee records. Failure to register or remit contributions attracts penalties and interest.

  • Disability pension — for permanent disability of at least 66.67%
  • Survivor pension — for dependants of deceased insured persons
