Taxation Chamber progressive tax (0%–15%), NSIF social security (8% employee + 17% employer). Monthly computation per official bands.
NSIF employee contribution (8%) is fully deductible from taxable income before PAYE is calculated. Employer NSIF (17%) is an additional cost shown in employer chart.
Four monthly bands: 0% on SDG 0–10,000; 5% on SDG 10,001–40,000; 10% on SDG 40,001–70,000; 15% above SDG 70,000. Applied monthly to taxable income (after NSIF deduction).
Yes — the employee's mandatory 8% NSIF contribution is fully deductible from gross pay before calculating PAYE. This reduces your taxable income and therefore your PAYE tax. The employer's matching 17% contribution is a separate employer cost.
The National Social Insurance Fund (NSIF) provides social security coverage for employees, including pension, disability, and survivor benefits. Total contribution is 25% (employee 8% + employer 17%).
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 SDG earned) may be higher due to progressive bands.
Marginal rate is the tax rate on your next SDG of income (your current band). Effective rate is your total tax divided by total income. Because of progressive bands, your marginal rate is typically higher than your effective rate.
Beyond NSIF, there may be pension contributions, union dues, and other statutory deductions depending on employer policy. Always consult your employer or a Sudanese tax professional for comprehensive information.
