What is Year-End Tax Settlement? (Yeonmal Jeongsan)

Yeonmal Jeongsan is the process of reconciling the taxes already withheld from your monthly salary with your actual final tax liability for the year. By applying various social insurance deductions, credit card spending, and rent credits, you determine if you've overpaid (Refund) or underpaid (Payable). For foreigners in Korea, this is essential to maximize refunds.

19% Flat Tax Rate

Foreign workers can choose to pay a flat 19% tax on their gross income instead of the progressive tax (6~45%).

  • Good for: High earners (usually > ~150M KRW).
  • Trade-off: No deductions allowed (Credit card, Rent, Medical, etc. are ignored).
  • Valid for: 20 years from start of work.

Progressive Tax (Standard)

Standard Korean tax system used by locals. Tax rate increases with income (6% ~ 45%).

  • Good for: Most employees (< 150M KRW).
  • Benefit: Allows various deductions (Card, Rent, Medical) to lower your tax base.

Don't worry about choosing now. Your company's accounting team (or tax accountant) should automatically apply the more favorable method for you. However, to benefit from the Progressive Tax method, you MUST submit your income deduction documents (PDF from Hometax) during the Year-End Settlement period (Jan-Feb).
