The agreed salary is never the price of the employee — compute before signing
In short: A first recruitment rarely fails on the person; it fails on math and paperwork. On math: 34.5 % of social-security contributions — 9 % withheld from the employee, 25 % charged to the employer, 0.5 % for works-council funding — plus source-withheld income tax and a minimum wage raised to 24,000 DZD, which also floors the contribution base. Practical result: an employee agreed at 60,000 DZD net approaches 80,000 DZD of monthly employer cost. On paperwork: a pre-hiring declaration ten days before start date, employer affiliation, worker registration, medical visit, payslips and the quarterly salary return — late filing costing 15 % then 5 % per month, and each omitted employee 1,000 DZD in fines. This article walks computation, formalities and risks, text by text.

1. 1. What does an employee really cost? The end-to-end computation
Three figures coexist and must never be confused: the net salary the candidate negotiates, the gross salary written in the contract, and the employer cost borne by the company. Between the last two sits social security: 9 % withheld from the employee's gross, 25 % charged to the employer, plus 0.5 % of total gross payroll for works-council funding.
| Computation step | Rule | Example — 65,000 DZD gross |
|---|---|---|
| Employee contribution | 9 % of gross, withheld before income tax | − 5,850 DZD |
| Income-tax withholding | Monthly source withholding on the progressive scale in force | Per bracket |
| Net salary paid | Gross − 9 % − IRG | ≈ what the candidate negotiated |
| Employer contribution | 25 % of gross | + 16,250 DZD |
| Works-council funding | 0.5 % of total gross payroll | + 325 DZD |
| Total employer cost | Gross × ~1.255 | ≈ 81,575 DZD |
The 1.255 multiplier is the most useful tool in a manager's kit: multiply gross by it and you have the real price of the post, before any benefit. Two safeguards complete the computation: the floor — the national guaranteed minimum wage was raised to 24,000 DZD by presidential decree No. 26-01 of 7 January 2026, and that value also floors the contribution base; and the uncapped base — unlike other systems there is no contribution ceiling: a highly paid manager carries proportionally identical charges.
A final scope reminder: this computation concerns employees. A majority-shareholder manager falls under CASNOS — the non-salaried regime with distinct bases, quantified in our article How much to invoice to net 100,000 DZD? The two funds do not merge, and confusing the two regimes is the most common declaration error of young companies.
2. 2. Which formalities should start before the first day?
The hire is documented before the employee walks through the door — every missing document becomes a weakness in a dispute or audit.
The written contract
The employment relationship is formalised in writing before taking up the post. The contract type — open-ended as the principle, fixed-term only in the cases exhaustively listed by Law No. 90-11 — states the post classification, the basis for everything downstream (probation, grading, notice).
Employer affiliation
First hire means the company itself must affiliate with CNAS as employer (register extract, tax ID, planned posts list). Without an employer number, no later declaration is possible.
The pre-hiring declaration
Declare the hire at least ten days before start date — the document that opens the employee's rights and protects the employer.
Worker registration and medical visit
Affiliate the worker with CNAS under his personal social-security number and organise the pre-hiring medical examination — an undeclared worker is not covered in case of a work accident, a situation exposing the employer twice over.
3. 3. Open-ended, fixed-term, internship: which contract for which starting need?
The contract is not paperwork detail: it decides what the employee's exit will cost as much as their entry.
| Form | When it justifies itself | The trap |
|---|---|---|
| Open-ended (CDI) | The default contract: any permanent post, even part-time | Its termination follows formal procedures — anticipate them in grading and appraisal |
| Fixed-term (CDD) | Only in the cases enumerated by law: replacement of an absent employee, one-off peak, seasonal works… | Concluded outside those cases it is requalified into permanent before labour courts, retroactive indemnities included |
| Part-time | Genuine partial needs; rights pro-rated to time worked | Contributions follow actual pay — no magic flat rate |
| Internship / insertion / apprenticeship | Dedicated schemes with their own funding regimes | An "internship" actually filling a permanent post gets requalified: qualification follows facts, not labels |
The probation period, framed by Law No. 90-11 per post qualification and renewable once only subject to express writing, is the sole legal space where either party can withdraw simply. It must still be provided in the contract and genuinely appraised: extending without writing or working beyond its duration without decision equals definitive integration. And one rule crosses all forms: the post classification written in the contract commands grading, probation and notice — drafting it vaguely to keep margin means conceding that margin to the employee on the first disagreement day.
4. 4. Which obligations return after the hire?
The hire installs a monthly and quarterly mechanics that must run without interruption:
| Deadline | Obligation | Vigilance point |
|---|---|---|
| Each payroll | Detailed payslip: gross, contributions, withheld IRG, net paid | The payslip is the evidence in a dispute — "cash by hand, no paper" proves nothing |
| Monthly or quarterly | CNAS contribution payment depending on headcount | Late-payment interest runs fast |
| Quarterly | Salary declaration (DAS) | The piece the audit cross-checks — it must match payslips and payments |
| Ongoing | Staff register kept current | Required from the first employee during labour inspections |
| Yearly | Works-council funding (0.5 %) allocated as required | A contribution distinct from strict social security |
And general coherence plays out across three documents: payslips, CNAS declarations and bank movements tell the same story — otherwise that gap is precisely what feeds a reassessment. Our article Tax audits: deadlines, rights and preparation describes how these reconciliations are performed.
5. 5. What does a sloppy hire cost? The sanctions, text by text
Social-security sanctions are progressive and stack with labour-law risk:
| Breach | Sanction | Basis |
|---|---|---|
| Failure to file the salary declaration | 15 % of contributions due, plus 5 % per month late | Law No. 83-14, art. 16 |
| Employee omitted from the declaration | Fine of 1,000 DZD per omitted worker — and full recovery of contributions | Law No. 83-14, art. 16 bis |
| Undeclared employee victim of a work accident | Employer liable for consequences, outside any coverage | Work-accident regime |
| Fixed-term contract concluded outside admitted cases | Requalification into permanent, retroactive indemnities included — a frequent litigation scenario | Law No. 90-11 · litigation practice |
| Salary below the minimum wage | Labour-code sanctions and recovery — the floor now stands at 24,000 DZD | Presidential decree No. 26-01 |
The real risk is not the fine: it is the inverted chronology. A hire documented after the fact — contract signed late, forgotten pre-declaration, reconstructed payslips — turns every document into an admission about dating. In the files we see pass, it is almost never the contribution rate that hurts; it is the date at which the papers claim everything began.
