What is the CNAS in Algeria?

The CNAS (National Social Insurance Fund) manages social security for salaried workers in Algeria: sickness, maternity, work accidents, invalidity and retirement. Every employer must affiliate its employees to it.

What is the CNAS contribution rate in 2026?

The overall rate is 34.5 % of the gross payroll: 25 % payable by the employer, 9 % payable by the employee (withheld at source) and 0.5 % charged to the social works fund (fonds des œuvres sociales). The branch by branch split is set by article 2 of décret exécutif 94-187 as rewritten by décret exécutif 15-236 (Journal officiel no. 49 of 16 September 2015): social insurance 13 %, work accidents and occupational illness 1.25 %, retirement 18.25 %, unemployment insurance 1.5 %, early retirement 0.5 %.

How do you affiliate an employee to the CNAS?

The employer has 10 working days after hiring to declare the employee to the CNAS using the affiliation form + employment contract + copy of the national ID card. The declaration is made at a branch or through the Altawathik platform.

What is the DAS declaration?

The DAS (annual salary declaration) is an employer obligation reporting the detail of salaries paid and contributions settled over the year. Quarterly for large organisations, annually before 30 April for SMEs.

What penalty applies to late affiliation?

Late affiliation exposes the employer to the fine provided for by loi 83-14 as amended and to late-payment surcharges on the contributions due, with forced collection organised by loi 08-08. The exact amounts are set by the CNAS at the time of the audit: ask your branch for the statement, since regularising voluntarily always costs less than being reassessed.

How do you obtain the Chifa card for an employee?

Once the employee is affiliated, they go to their CNAS branch with their national ID card, a photograph and the affiliation certificate to trigger the issue of the Chifa card (3 to 4 weeks).

What is the difference between CNAS and CASNOS?

CNAS covers salaried workers. CASNOS covers non-salaried workers (traders, craftspeople, liberal professions, auto-entrepreneurs). Both can apply to someone who is simultaneously an employee and self-employed.

CNAS contribution table

Split of the social security contribution rate for salaried workers, exactly as written in décret exécutif n° 15-236 of 3 September 2015, which rewrites article 2 of décret exécutif n° 94-187. The global rate is 34.5 % of gross salary.

The 34.5 % rate, branch by branch
Branch	Employer share	Employee share	Social works fund share	Total
Social insuranceSickness, maternity, invalidity, death	11.5 %	1.5 %	0 %	13 %
Work accidents and occupational illness	1.25 %	0 %	0 %	1.25 %
Retirement	11 %	6.75 %	0.5 %	18.25 %
Unemployment insurance	1 %	0.5 %	0 %	1.5 %
Early retirement	0.25 %	0.25 %	0 %	0.5 %
Total	25 %	9 %	0.5 %	34.5 %

The decree gives the social works fund (fonds des œuvres sociales) its own column. It sits neither on the employee nor in the employer column: the employer column in the official table stops at 25 %.

Corresponding monthly amounts, by gross salary levelThe amounts below are a calculation, not an official schedule: they are the table's percentages applied to a monthly gross salary. IRG income tax is not included, it is a deduction separate from the CNAS contribution.
Monthly gross salary	Employee deduction (9 %)	Employer share (25 %)	Total employer cost
24 000 DZDSNMG	2 160	6 000	30 000
40 000 DZD	3 600	10 000	50 000
60 000 DZD	5 400	15 000	75 000
80 000 DZD	7 200	20 000	100 000
100 000 DZD	9 000	25 000	125 000
150 000 DZD	13 500	37 500	187 500

The 24,000 DZD row matches the SNMG in force since 1 January 2026 (décret présidentiel n° 26-01). It is a reading landmark: it does not mean the CNAS base is bounded at that amount.

What these rates apply to

The contribution base is set by ordonnance n° 95-01 of 21 January 1995, cited in the recitals of decree 15-236. Confirm your own base with your CNAS branch before computing any back payment: the pay elements taken into account go beyond basic salary.
