CNSS contributions Benin: rates, base and 2026 cost

CNSS contributions Benin amount to between 20% and 23% of gross salary in 2026: 3.6% paid by the employee and 16.4% to 19.4% paid by the employer, depending on the occupational risk rate. They are calculated on total pay, with no ceiling. Below are the rates by branch, the contribution base, the calculation, an example for an SME, the filing process and the mistakes that come up in inspections.

CNSS contributions Benin: rates by branch in 2026

The Caisse nationale de sécurité sociale (CNSS, the national social security fund) provides social protection for private-sector employees. The rates below are those published as at 1 January 2024 by CLEISS, the French public liaison body for social security, and applied in 2026.

An uncapped base

Contributions are calculated on total gross earnings. Unlike other countries in the region, there is no ceiling: a salary of FCFA 2,000,000 contributes on FCFA 2,000,000. For a group that also runs subsidiaries in Cameroon or Senegal, this is a parameter not to copy from one country to another.

The occupational risk rate

The work-injury rate ranges from 1% to 4% depending on the risk of the activity. It is assigned to the employer according to its activity: a design office and a construction site do not carry the same rate. Check your classification at registration, then whenever your main activity changes.

Calculating CNSS contributions Benin step by step

1. Rebuild the month’s gross pay: base salary, overtime, bonuses, allowances and benefits in kind. In Benin, the General Tax Code sets flat values for several benefits in kind (housing, vehicle, electricity): document the value used for CNSS and apply it consistently.
2. Apply 3.6% to that gross for the employee deduction.
3. Apply 6.4% and 9% for the employer pension and family benefit shares.
4. Apply your occupational risk rate, between 1% and 4%.
5. Reconcile total declared bases with the payroll ledger before filing.

Worked example: an SME with 20 employees

As an illustration, take a distribution company in Cotonou with 20 employees and a monthly gross payroll of FCFA 5,000,000, classified at 2% occupational risk.

Over the year, this SME’s CNSS contributions Benin reach FCFA 12,600,000, of which FCFA 10,440,000 is borne by the company. If it were classified at 4%, the employer charge would rise by FCFA 100,000 a month, or FCFA 1,200,000 a year: the risk classification deserves a check. On top of these contributions comes the employer payroll tax, which is not a CNSS contribution (see below).

At individual level, the absence of a ceiling gives a constant rate: for an employee on the minimum wage (SMIG), set at FCFA 52,000 a month since 1 January 2023, the employee deduction is FCFA 1,872 and the employer share, at 2% occupational risk, FCFA 9,048. For a FCFA 1,500,000 salary, they are FCFA 54,000 and 261,000.

Budgeting a new hire or a new entity

Because there is no ceiling, budgeting is a matter of simple multiplication, provided gross pay is complete. For a new hire, add to the planned gross salary the benefits in kind and regular allowances, apply 3.6% for the net pay offer and 16.4% to 19.4% for the employer budget, then add the 4% VPS. For a new subsidiary, the occupational risk rate is the only parameter that varies: ask for your classification at registration rather than assuming the lowest rate. A budget built at 1% and a notified rate of 3% means a 2-point gap on the whole payroll from the first month, which is exactly the kind of difference a finance director discovers too late.

What does not count as CNSS contributions Benin

Two levies appear on the same payslip but are collected by the tax administration:

• the versement patronal sur salaires (VPS, an employer payroll tax): 4% borne by the employer (2% for private schools), on the same base as ITS, paid to the tax office;
• the impôt sur les traitements et salaires (ITS, the salary income tax), withheld from salary on a progressive scale, with the ORTB broadcasting levy in March and June.

For the full path from gross to net, with the ITS scale, see our guide to payroll management in Benin.

Filing and paying CNSS contributions Benin

Since February 2020, the tax authority (DGI) and the CNSS have offered a single online return for declaring and paying salary taxes and social contributions, aimed first at medium and large companies. One entry feeds ITS, VPS and CNSS, so the bases must match line by line.

ITS and VPS are due by the 10th of the following month. For the CNSS deadline, secondary sources disagree: use the date shown in your filing account or confirmed in writing by the CNSS, and set your payroll close accordingly.

Before each filing, check three points: every employee of the month is registered, including new starters; the declared occupational risk rate is the one notified; the CNSS and ITS bases in the single return match the payroll ledger.

Common mistakes with CNSS contributions Benin

• Applying a ceiling. Reusing another country’s settings under-declares every high salary.
• Excluding benefits in kind. Housing, a vehicle or electricity paid by the employer are part of pay; leaving them out creates a multi-year adjustment in an inspection.
• Using the wrong occupational risk rate. A 2-point gap on a FCFA 5,000,000 payroll is FCFA 100,000 a month.
• Counting VPS as CNSS. The employer cost is right, but reconciliations by body become wrong.
• Paying without declaring each employee. Employee rights (pension, maternity, work injury) rest on an accurate named return.

Special cases

First job and domestic staff: CNSS registration conditions a tax exemption

The Tax Code exempts from VPS, for two years, pay for the first job of an employee of Beninese nationality, provided the employee is declared to the CNSS. Employers of domestic staff are also exempt from VPS, provided they declare and pay CNSS contributions. Without CNSS registration, the exemption falls away.

Interns

Compulsory internship pay, within the Tax Code limits (three months at most, under 30, up to three times the SMIG a month), is exempt from ITS and VPS. Confirm the social security treatment of interns with the CNSS before leaving them out of returns.

Maternity

Maternity leave lasts 14 weeks. Maternity cash benefits are funded by the 0.2% share included in the 9% family benefit rate.

Automating CNSS contributions Benin

With an uncapped base, the calculation looks simple; the difficulty lies elsewhere: capturing every variable item of the month, applying the right occupational risk rate and producing a single return consistent with ITS and VPS. An HRIS that feeds payroll from time and absence data for accurate CNSS contributions Benin, with an HR document vault to keep payslips and supporting documents, secures these steps.
