IRG Withholding, Computed Right Every Month
The 2022 Finance Law bracket, validated against a decade of real payroll
The Algerian progressive-bracket income tax withholding (IRG), with reference figures captured directly from a real production system that computed this exact tax for over a decade.
The bracket table (threshold / rate / deduction) lives as editable data, not code - update it the day the Finance Law changes, no module upgrade required.
Validated against a real production Algerian payroll system that computed this exact tax for over a decade (2013-2026) - the test suite's reference figures were captured directly from that system's own output.
Full partial-month fidelity: a mid-month hire, termination, or unpaid-leave period scales the imposable base up to a full month before the bracket lookup, then scales the computed tax back down - matching how production has always handled it.
A long-standing indexing quirk above 160,000 DZD/month is preserved intentionally rather than silently "corrected" - production reference figures confirm it is what has actually been withheld and declared for years.
Standalone, or as the tax engine behind Algeria - HR Payroll
Use it on its own as an IRG simulator against any Human Resources setup, or install Algeria - HR Payroll alongside it to wire IRG straight into full payslip computation - CNAS-employee-deduction-folded-in base included.
