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?

Affiliation is done at a branch or through the Altawathik platform, with the affiliation form, the employment contract and a copy of the national ID card. The deadline is the one in article 10 of loi n° 83-14: the affiliation request must be sent within ten (10) days following the recruitment of the worker. The text says ten days, not ten working days. Loi n° 04-17 only appends a second paragraph covering the self-employed to that article and leaves the first one unchanged. After that deadline article 12 lets the fund affiliate the worker of its own motion, and article 13 puts the cost of not affiliating at 1,000 DA per unaffiliated worker, rising before the court to 10,000 to 20,000 DA per worker under article 41. The full scale is on /penalites-cnas-employeur-algerie.

What is the DAS declaration?

The DAS (annual salary declaration) is the nominative declaration of salaries and employees that article 14 of loi n° 83-14 requires from every employer, within thirty (30) days following the end of each calendar year. It shows the remuneration received between the first and the last day, quarter by quarter, together with the amount of contributions due: it is annual, with a quarterly breakdown inside it. The same article adds that this periodicity may be changed by regulation. What is quarterly for an employer with fewer than ten workers is the payment of contributions under article 21, not the DAS. Filing late costs 15 % of the contributions due, plus 5 % per month (article 16). See /penalites-cnas-employeur-algerie.

What penalty applies to late affiliation?

Article 13 of loi n° 83-14, as rewritten by loi n° 04-17, sets a penalty of 1,000 DA per unaffiliated worker, imposed and collected by the fund. Before the court, article 41 adds a fine of 10,000 to 20,000 DA per unaffiliated worker and a prison term of two to six months, or one of those two penalties, raised to 20,000 to 50,000 DA and two to twenty four months on a repeat offence. The full scale, article by article, is on /penalites-cnas-employeur-algerie.

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. That processing time belongs to the CNAS and we do not state it.

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.

Employer filings and their statutory deadlines

Four obligations, four deadlines, all of them set by loi n° 83-14 of 2 July 1983 on the obligations of persons covered by social security. Loi n° 04-17 of 10 November 2004 rewrote part of it, but it leaves article 14 and article 21 untouched, so their 1983 wording is the one that applies.

Declaration of activity: within ten (10) days following the start of the activity (article 6, as rewritten by article 5 of loi n° 04-17). Failing to file it costs 5,000 DA plus a 20 % surcharge per month of delay (article 7).
Affiliation request for an employee: within ten (10) days following the recruitment of the worker (article 10, first paragraph). The text says ten days, not ten working days. Loi n° 04-17 merely appends a second paragraph covering the self-employed and leaves the first one unchanged.
Annual salary declaration (DAS): within thirty (30) days following the end of each calendar year (article 14). It is a nominative declaration of salaries and employees, showing the remuneration received between the first and the last day, quarter by quarter, together with the amount of contributions due. The same article adds that this periodicity may be changed by regulation.
Payment of contributions: within the first fifteen (15) days following the end of each calendar quarter if the employer has fewer than ten (10) workers, and within the first fifteen (15) days following the end of each month if it has more than nine (9) workers (article 21). What is quarterly for a small employer is therefore the payment, not the DAS, which stays annual.
All four deadlines were read on the image render of pages 1217 and 1218 of Journal officiel no. 28 of 5 July 1983: https://www.joradp.dz/FTP/jo-francais/1983/F1983028.pdf

Contributions and penalties

The overall social security contribution rate is 34.5 % of the gross salary, split into 25 % payable by the employer, 9 % payable by the employee and 0.5 % charged to the social works fund (fonds des œuvres sociales), per article 2 of décret exécutif 94-187 as rewritten by décret exécutif 15-236. The branch by branch detail and the matching amounts are in the table at the top of this page.

In the event of non-compliance:
Failure to affiliate: 1,000 DA per unaffiliated worker, imposed by the fund (article 13 of loi 83-14, rewritten by article 9 of loi 04-17), then before the court a fine of 10,000 to 20,000 DA per unaffiliated worker and two to six months in prison, or one of those two penalties (article 41). The statement of contributions due is what the CNAS sets at the time of the audit.
Failure to declare salaries: a 15 % penalty on the contributions due + a 5 % surcharge.
Failure to declare the activity: a 5 000 DA fine + a 20 % surcharge.
