Key takeaways: In 2026, CNSS sanctions in Morocco include a 3% surcharge in the first month of late payment + 0.5% per additional month (since April 2025), a fine of 1,000 MAD per unregistered employee, and 50 MAD/month/employee for declarations delayed more than 7 months. Criminal penalties can reach 50 to 600 MAD per employee.
CNSS Sanctions Framework
The CNSS (Caisse Nationale de Sécurité Sociale) has a range of administrative, financial, and criminal sanctions to enforce contribution collection and compliance with reporting obligations. The penalty regime was strengthened in April 2025 with new late payment surcharges.
Late Payment Surcharges
Since April 2025, the late payment surcharge regime applies as follows:
| Delay Period | Applicable Surcharge |
|---|---|
| First month | 3% of the amount due |
| Each additional month | 0.5% of the amount due |
| Example: 6 months late | 3% + (5 x 0.5%) = 5.5% |
These surcharges are calculated on the total unpaid contributions (both employer and employee shares). They accrue automatically from the due date, without prior formal notice.
Payment Deadline
CNSS contributions are due the month following the work period. Any delay automatically triggers surcharges. Payment is made through the Damancom platform.
Non-Registration Penalties
An employer who fails to register employees with the CNSS faces:
- 1,000 MAD fine per undeclared employee
- Retroactive registration with back-payment of contributions
- Late payment surcharges on all outstanding contributions
Non-registration is one of the most severely penalized offences, as it deprives employees of their social rights (health coverage, retirement, family allowances).
Late Declarations
The monthly salary declaration must be submitted via Damancom within regulatory deadlines. In case of delay:
| Situation | Penalty |
|---|---|
| Declaration delay > 7 months | 50 MAD/month/employee |
| Incomplete declaration | Formal notice + regularization |
| Total absence of declaration | Estimated assessment by CNSS |
Estimated assessment allows the CNSS to calculate contributions due based on available information. The estimated amount is subject to surcharges and may be adjusted through a subsequent audit.
Criminal Penalties
Beyond administrative sanctions, the social security legislation provides for criminal penalties:
- Fine of 50 to 600 MAD per employee for non-declaration or false declaration
- Imprisonment of 1 to 3 months in case of repeat offence
- Possible cumulation of administrative and criminal sanctions
These criminal penalties are imposed by the court and do not replace late payment surcharges or administrative fines.
Document Retention
The employer must retain all social documents for 10 years:
- Payslips and payroll register
- CNSS declaration forms
- Proof of contribution payments
- Employment contracts
During audits, the absence of supporting documents worsens the employer’s position and may trigger an estimated assessment with surcharges.
CNSS Audit Procedure
How Audits Work
The CNSS may conduct desk-based or on-site audits. The typical process unfolds as follows:
- Prior notification: the employer receives an audit notice
- On-site verification: inspectors examine payroll registers, payslips, contracts, and declarations
- Cross-checking: comparison of declarations with accounting records
- Audit report: findings of any irregularities
- Adjustment notification: amount of recalled contributions + surcharges
- Appeals: the employer may contest before the appeals commission
Verification Period
CNSS inspectors may verify the last 10 years of declarations. This is why retaining documents for this duration is essential.
Common Audit Focus Areas
Inspectors typically verify:
- Consistency between declared salaries and payslips
- Completeness of declared employees (including paid interns)
- Correct application of the 6,000 MAD/month cap
- Compliance with declaration and payment deadlines
- Undeclared benefits in kind
How to Avoid Sanctions
To ensure CNSS compliance:
- Declare and pay contributions on time via Damancom
- Register every new employee before they start work
- Retain all social documents for at least 10 years
- Conduct periodic payroll audits to detect anomalies
- Engage a chartered accountant to secure your declarations
Frequently Asked Questions
Are late payment surcharges negotiable?
No. Late payment surcharges apply automatically and are not subject to negotiation. However, the employer may request a payment plan from the CNSS to regularize their situation. A payment plan does not cancel surcharges already calculated.
What should I do upon receiving a CNSS adjustment notice?
The employer has a deadline to contest the adjustment before the CNSS appeals commission. It is advisable to engage a chartered accountant to analyse the audit findings, identify potential errors, and prepare the contestation. Payment of uncontested amounts must be made within deadlines to avoid additional surcharges.
Can an employee report non-registration?
Yes. Any employee can report to the CNSS that their employer has not registered them or is not declaring contributions. The CNSS may then initiate an audit. The employee can also contact the labour inspectorate.
