How It's Calculated
Year-end tax settlement follows these steps:
1. Total Salary − Non-taxable allowances = Gross Taxable Income 2. Employment Income Deduction (근로소득공제): sliding scale 70%–2% based on income brackets 3. Income Deductions: Personal (₩1.5M/person), National Pension, Health Insurance, Employment Insurance 4. Special Deductions: Insurance premiums, medical expenses (>3% of salary), education, housing rent/interest, donations 5. Taxable Income = Gross − Employment Deduction − Income Deductions − Special Deductions 6. Calculated Tax = Progressive rates (6%–45%) 7. Tax Credits: Child credit, retirement pension (12–15%), standard credit (₩130K) 8. Determined Tax = Calculated Tax − Credits 9. Refund/Additional = Already withheld − Determined Tax (positive = refund)
