  • Gross salary (as calculated in Section 29.3)
  • Capped at €9,000 per month (as of 2025)
  • Includes all taxable components
  • Excludes exempt allowances (e.g., meal vouchers up to limit)

Example:

  • Gross salary: €10,000/month
  • Contribution base: €9,000 (capped)

  • Dependency Insurance (1.4%): €3,500 × 1.4% = €49.00
  • Employment Fund (2%): €3,500 × 2% = €70.00
  • Total Employee: €497.00

Step 3: Calculate Net Salary

  • Gross salary: €3,500.00
  • Employee social charges: €497.00
  • Net salary: €3,003.00
