Algeria does levy personal income tax on salaries. The employer is the withholding agent: it deducts IRG monthly from payroll (retenue à la source) and remits it on the G50 declaration (PwC — Taxes on personal income; Rivermate). The progressive scale was introduced by the Loi de Finances 2022 (FL 2022), effective 1 January 2022, and remains the current scale for 2025 (no replacement scale published for 2025/2026 as of the research date).

[RESEARCH GAP — reviewer to confirm] The exact ordering (abattement vs. social-contribution deduction) and whether the 30,000 DA exemption is a clean gate or interacts with the abattement floor should be confirmed against the DGI's IRG-Traitements-et-Salaires text before finalizing.
CNAS social security runs across five branches. The total statutory rate is 35% of gross salary = employer 26% + employee 9% (PwC — Other taxes; Rivermate). Contributions are levied on gross salary with no upper ceiling (uncapped) for the general salaried regime; the effective floor is the SNMG minimum wage — contributions cannot be based on less than the SNMG (PwC; Rivermate; CLEISS).

The SNMG is a single national figure applying to public and private sectors. It is the floor for CNAS contributions (contributions cannot be based on less than the SNMG).
Context only (not a payroll deduction): the unemployment allowance (allocation chômage) was raised to 18,000 DA alongside the 2026 SNMG hike (Algeria Invest).
Conservative Defaults
| Unknown | Conservative default | Why |

| Sector (construction add-on) | Assume no CACOBATPH 0.375% add-on unless told construction | Avoids over-stating; flag if sector unknown |

| Abattement amount | Apply 40% floored 1,000 / capped 1,500 DA/month | Statutory bounds |
| CNAS base below SNMG | Floor the contribution base at the SNMG (20,000 DA for 2025) | Contributions cannot be below SNMG |
| CNAS ceiling | None — compute on full gross (uncapped) | General salaried regime is uncapped |
| Currency | Algerian Dinar (DZD) | Wages are paid in Dinars |
| Headline CNAS split | 26% employer / 9% employee / 35% total | Operative figure per PwC/Rivermate |
When an input is missing or ambiguous, apply the conservative assumption (the one that does NOT understate withholding/contributions) and FLAG it for the reviewer.

All figures use the FL 2022 (2025-current) IRG scale, CNAS employee 9% and the 40% abattement (capped 1,500 DA/month). IRG base = (gross − 9% CNAS − abattement), annualised, scaled, ÷ 12. The 30,000 DA/month full exemption overrides to IRG = 0. Amounts rounded to the cent. Construction add-on excluded (general sector).
Inputs: Gross 24,000 DA/month (the 2026 SNMG).
Bank line example: VIR SALAIRE — MARS credit 21,840.00 DA.
Inputs: Gross 30,000 DA/month.
Inputs: Gross 45,000 DA/month.
Inputs: Gross 80,000 DA/month.
Inputs: Gross 400,000 DA/month.
Employer total cost table

| Employer CNAS 26% | 0.26 × 80,000 | 20,800.00 |
| Total employer cost | sum | 100,800.00 |
Building on Example 4 (gross 80,000 DA/month, general sector):
Check: 80,000 + 20,800 = 100,800.00. Employer-on-top burden = 20,800 = 26% of gross. (Construction add-on would add 0.375% × 80,000 = 300.00 DA on top — excluded here.)

IRG monthly full exemption
Salaries up to 30,000 DA/month are fully exempt from IRG, regardless of the annual-scale outcome. Apply this exemption as a hard gate: if monthly gross ≤ 30,000 DA, IRG = 0.DGI / Radio Algérienne — news.radioalgerie.dz/fr/node/3142
Salary abattement
A 40% deduction is applied to salary income before the scale, floored at 12,000 DA/year (1,000 DA/month) and capped at 18,000 DA/year (1,500 DA/month).Radio Algérienne — node/3142
IRG base calculation order
IRG is computed on salary net of employee social contributions (the 9% CNAS employee share is deducted first) and after the 40% abattement, then the annual scale is applied: 1. Start from monthly gross salary. 2. Subtract employee CNAS (9%) → salary after social contributions. 3. Subtract the 40% abattement (min 1,000 / max 1,500 DA per month) → monthly IRG base. 4. Annualise (× 12), apply the progressive scale (subtract-method), divide by 12 → monthly IRG. 5. If monthly gross ≤ 30,000 DA, override IRG to 0 (full exemption).IRG order of operations, section 2

Reconciliation note
CLEISS itemises the employer side as 25% + 0.5% FNPOS social-housing levy = 25.5%; adding 0.5% for œuvres sociales (social works) brings the headline employer figure to the commonly cited 26%. The Big-4 / payroll summaries (PwC, Rivermate) state the headline as a flat employer 26% / employee 9% / total 35%. Both describe the same regime; the 35% headline includes the social-works and housing-fund components that CLEISS lists separately. Use 26% employer / 9% employee / 35% total as the operative payroll figures, with the CLEISS table as the branch detail.CLEISS; PwC; Rivermate

Required inputs
1. Monthly gross salary in DZD (and whether it is the ordinary/fixed base). 2. Tax/fiscal year (defaults to 2025 scale). 3. Sector (to decide the CACOBATPH 0.375% construction add-on). 4. Whether the salary is at or below the SNMG floor (20,000 DA for 2025 / 24,000 DA for 2026). 5. Any non-ordinary pay components (bonuses, primes, indemnités) and their treatment.

Tier 1 Rules
1. IRG is employer-withheld monthly (retenue à la source) and remitted to the DGI on the G50; never skip it for salaried staff (PwC; Rivermate). 2. Apply the IRG base order: gross → minus 9% CNAS → minus 40% abattement (1,000–1,500 DA/month) → annualise → progressive scale (subtract-method) → ÷ 12. 3. Salaries ≤ 30,000 DA/month are fully IRG-exempt — override IRG to 0 (DGI/Radio Algérienne). 4. CNAS is employee 9% + employer 26% = 35% total, on uncapped gross, floored at the SNMG (PwC; Rivermate; CLEISS). 5. The CNAS contribution base can never fall below the SNMG (20,000 DA for 2025; 24,000 DA for 2026). 6. Construction / public-works employers add CACOBATPH 0.375% each (employer and employee) (CLEISS). 7. Wages are paid in Algerian Dinars. 8. CNAS contributions are remitted monthly; the DAS annual return is due 31 January; the G50 is due by the 20th of the following month (Rivermate; Radio Algérienne; Fatoura). 9. Every output is an estimate pending licensed-accountant sign-off.PwC; Rivermate; DGI/Radio Algérienne; CLEISS; Fatoura

Onboarding fallback steps
If the engagement lacks key data: 1. No prior payroll register (livre de paie) available → request the last 3 months of payslips, G50 declarations, and CNAS bordereaux to back-solve the rates actually applied. 2. Unknown sector → default CACOBATPH off, FLAG; confirm before the first remittance. 3. Salary near the SNMG → confirm the contribution base is floored at the SNMG (20,000 DA for 2025 / 24,000 DA for 2026), never below. 4. Year ambiguity → default to the 2025 (FL 2022) scale; verify whether any new finance law has replaced it for periods after the research date. 5. Mixed self-employed income → route non-salarié income to a separate treatment; the non-salariés CNAS band (216,000–4,320,000 DZD/year, CLEISS) and IRG treatment differ.CLEISS

Registration requirements
Employers must register with CNAS as an affilié employeur and obtain an employer number before the first payroll; each employee is registered and assigned a social security number. Registration is triggered by hiring the first employee — there is no monetary threshold; any employer of salaried staff must register (CNAS employer portal, cnas.dz/en/employer/). Tax registration (NIF — numéro d'identification fiscale) with the DGI is required for the G50.CNAS employer portal, cnas.dz/en/employer/
Penalties

Withholding obligation
NEVER skip IRG withholding for salaried employees — the employer is the legal withholding agent.PROHIBITIONS
Exemption threshold
NEVER apply IRG to a salary of 30,000 DA/month or less — it is fully exempt.PROHIBITIONS
Abattement requirement
NEVER omit the 40% abattement (capped 1,500 DA/month) before applying the IRG scale.PROHIBITIONS
CNAS floor
NEVER apply a CNAS contribution base below the SNMG (20,000 DA for 2025 / 24,000 DA for 2026).PROHIBITIONS
CNAS uncapped
NEVER cap CNAS contributions — the general salaried regime is uncapped.PROHIBITIONS
Employer CNAS share
NEVER forget the employer's 26% CNAS share on top of the employee's 9%.PROHIBITIONS
CACOBATPH restriction
NEVER add CACOBATPH 0.375% outside the construction / public-works sectors.PROHIBITIONS
G50 penalty uncertainty
NEVER state an exact IRG (G50) late-payment penalty — the precise figure is an unconfirmed research gap.PROHIBITIONS
Currency restriction
NEVER pay or compute wages in a foreign currency — Algerian Dinars only.PROHIBITIONS
Deadline compliance
NEVER miss the monthly G50 (20th) / CNAS remittance or the 31 January DAS deadline.PROHIBITIONS
Professional review requirement
NEVER present payroll computations as definitive — always label as estimated and direct to a licensed Algerian expert-comptable.PROHIBITIONS
