Algerian payroll must be explainable
Payroll software in Algeria should not only generate payslips faster. It must explain the calculation: base salary, monthly variables, CNAS contribution base, employee contribution, salary IRG, net pay, employer cost, declarations and accounting entry.
DZ Compta structures the payroll file around CNAS payroll calculation, salary IRG, payslip controls, social contributions, payroll automation and multi-company payroll.
Key points for 2026
For salaried workers in Algeria, the correct social security body is CNAS, not CNSS. The CNAS employer page states that, in the general case, the contribution rate is 34.5%: 25% employer share, 9% employee share and 0.5% of gross payroll for social works.
The DGI salary IRG page states that monthly salary income up to 30,000 DA is exempt, that higher brackets follow the progressive scale with abatements, and that non-monthly bonuses or reminders have a specific treatment. It also mentions the annual G29 declaration and the 2026 requirement to include the NIN for each employee.
What the software must control
A serious payroll workflow should cover:
- Complete employee file: identity, contract, entry date, RIB, NIN, company and establishment.
- Payroll items classified by CNAS base, IRG base, accounting account and period.
- Calculation of gross pay, CNAS employee share, employer share, salary IRG and net pay.
- Payslip that is readable and consistent with declarations.
- Review of entries, exits, absences, bonuses, reminders and abnormal net pay.
- Payroll accounting entry linked to accounting.
- Period locking after validation.
Link with accounting
Payroll does not stop at the payslip. Net pay becomes a liability to employees. CNAS contributions become social liabilities. IRG withheld becomes a tax liability. Employer contributions become part of payroll cost. The accounting journal and general ledger must explain these balances.

Practical takeaway
Reliable payroll is not a hidden formula. It is a monthly process that can be reviewed from the employee file to the payslip, declaration, payment and accounting entry.
