DGI progressive tax (0%–40%), INSS social security (5% employee + 5% employer, capped). Annual computation per DGI bands.
INSS employee contribution (5%, capped) is fully deductible from taxable income before PAYE is calculated. Employer INSS (5%, capped) is an additional cost shown in employer chart.
Ten annual bands: 0% on first CDF 524,160; 3%–5% on CDF 524,161–2,700,000; 10%–15% on CDF 2,700,001–7,260,000; 20%–25% on CDF 7,260,001–13,908,000; 30%–35% on CDF 13,908,001–21,168,000; 40% above CDF 21,168,000. Applied on an annual basis to taxable income (after INSS deduction).
Yes — the employee's mandatory 5% INSS contribution (capped on base salary) is fully deductible from gross pay before calculating PAYE. This reduces your taxable income and therefore your PAYE tax. The employer's matching 5% contribution is a separate employer cost, not deducted from your pay.
The Institut National de Sécurité Sociale (INSS) provides social security coverage for employees in the Democratic Republic of Congo, including pension, disability, and survivor benefits. Total contribution is 10% (employee 5% + employer 5%), with employee contribution capped on the base salary component.
Beyond INSS employer contribution (5%), employers may also face additional taxes depending on sector and organisation type. Always consult with a Congolese tax professional for comprehensive employer cost calculations.
Effective tax rate = (Total PAYE tax / Gross salary) × 100%. This shows the average percentage of gross salary paid in income tax. The marginal rate (on the next CDF earned) may be higher due to progressive tax bands.
Marginal rate is the tax rate on your next CDF of income (the highest band you're in). Effective rate is your total tax divided by total income. Because of progressive bands, your marginal rate is typically higher than your effective rate. Both matter for tax planning.
