In brief: Since 2019, the CNSS declaration in Morocco is monthly and must be filed electronically via the Damancom portal (damancom.ma). The employer must declare salaries and pay contributions by the 10th of the following month. Any delay incurs penalties of 3% for the first month and 1% for each additional month.
The Damancom Portal: Central Declaration Tool
The Damancom portal is the online platform of the National Social Security Fund (CNSS) that enables employers to manage all their declaration and payment obligations. Launched to modernise and simplify administrative procedures, Damancom has become the essential tool for social management in Morocco.
Key Damancom Features
- Online salary declarations: entering the salary declaration form (BDS) online
- Online contribution payments: secure payment by bank transfer or direct debit
- Employee management: registration, staff arrivals and departures
- Account consultation: declaration history, balances and certificates
- Certificate requests: compliance certificate, affiliation certificate
To access Damancom, the employer must hold a CNSS affiliation number and create an online account with their credentials.
Transition to Monthly Declarations
Reform Context
Before 2019, CNSS declarations were filed on a quarterly basis. The transition to monthly declarations was introduced to:
- Improve real-time contribution tracking
- Reduce payment arrears
- Strengthen employee social protection through more frequent updates of their entitlements
- Align the Moroccan system with international standards
Declaration Calendar
The monthly declaration must be filed and contributions paid by the 10th of the month following the relevant payroll period. For example:
- January 2026 salaries → declaration and payment by 10 February 2026
- February 2026 salaries → declaration and payment by 10 March 2026
Content of the Salary Declaration
Salary Declaration Form (BDS)
The BDS is the core document of the CNSS declaration. It contains the following information for each employee:
- Employee’s CNSS registration number
- National Identity Card (CIN) number
- Employee’s full name
- Number of days worked during the month
- Declared gross salary (base + bonuses + benefits)
- Ceiling applied for branches subject to capping
Employer Summary
The BDS also includes an overall summary showing:
- Total number of declared employees
- Total payroll
- Total contribution amount (employer share + employee share)
- Amount payable
Employer Obligations
Company Affiliation
Any employer hiring one or more employees must register with the CNSS within 30 days of hiring the first employee. Affiliation is done by submitting an application to the relevant CNSS agency, accompanied by:
- Affiliation application form
- Copy of the trade register or company articles
- Copy of the legal representative’s CIN
- Professional tax (patente) registration certificate
Employee Registration
The employer must register each employee with the CNSS. This registration assigns the employee a unique number that follows them throughout their career. Required documents include:
- Registration application form
- Copy of the employee’s CIN
- Identity photograph
Reporting Staff Arrivals and Departures
Each staff movement (hiring or departure) must be reported to the CNSS:
- Arrival: to be declared in the month of hiring, via the monthly BDS
- Departure: to be declared in the month of leaving, indicating the contract end date and reason (resignation, dismissal, end of fixed-term contract, retirement)
Mandatory Online Payment
CNSS contribution payments must be made electronically via Damancom. Accepted payment methods are:
- Bank transfer to the CNSS account
- Automatic direct debit
- Online payment via the Damancom platform
Payment by cheque or cash is no longer accepted for companies registered on Damancom.
Late Payment Penalties
Applicable Surcharges
Late declaration or payment of contributions incurs surcharges calculated in accordance with the 1972 Dahir:
- 3% of the amount due for the first month of delay
- 1% additional for each subsequent month or fraction thereof
Penalty Calculation Examples
For a 3-month delay on contributions amounting to MAD 10,000:
- 1st month: 10,000 × 3% = MAD 300
- 2nd month: 10,000 × 1% = MAD 100
- 3rd month: 10,000 × 1% = MAD 100
- Total penalties: MAD 500 (i.e., 5% of the amount due)
Other Sanctions
In addition to financial surcharges, the employer may face:
- Enhanced inspections by the CNSS
- Adjustment of undeclared contributions
- Legal proceedings in cases of non-affiliation or fraud
- Inability to obtain compliance certificates required for public tenders
CNSS Certificates
Compliance Certificate
The CNSS compliance certificate confirms that the employer is up to date with declaration and payment obligations. It is required for:
- Participation in public tenders
- Obtaining certain bank loans
- Various administrative procedures
Affiliation Certificate
The affiliation certificate confirms that the company is duly registered with the CNSS and states its affiliation number.
Inspection and Adjustment
The CNSS has a body of inspectors authorised to conduct on-site inspections at companies. These inspections aim to verify:
- Compliance of declarations with actual remuneration paid
- Registration of all employees
- Adherence to declaration and payment deadlines
Where irregularities are found, the CNSS issues a contribution adjustment, together with late payment surcharges. The employer has the right to contest before the CNSS appeals commission.
Frequently Asked Questions (FAQ)
What happens if I do not declare my employees to the CNSS?
Failure to declare exposes the employer to financial penalties (late surcharges), adjustment of unpaid contributions and legal proceedings. The undeclared employee also loses their rights to social benefits (retirement, health, family allowances).
Can I correct a CNSS declaration already submitted?
Yes, it is possible to file an amended declaration via Damancom. Corrections should be made promptly to avoid additional penalties.
Is the CNSS declaration mandatory even if no salaries were paid?
Yes, the affiliated employer must file a declaration each month, even in the absence of salaries paid (nil declaration). This obligation continues as long as the company is affiliated with the CNSS.
How do I obtain a CNSS registration number for a new employee?
Registration is done via Damancom or directly at the local CNSS agency. The number is assigned within a few days of submitting the complete file.
