Taxes & Year-End Settlement

If you’re employed in Korea, income tax is withheld from your salary each month, and early each year (usually Jan–Feb) a year-end settlement (연말정산) reconciles your annual tax — you get a refund or pay more. Foreign workers may choose a flat-rate special option instead of the progressive rates (but lose deductions); whether it’s better depends on your situation. If you have freelance/business income, you also file a separate global income tax return each May.

What to bring

  • ARC
  • Withholding receipt for earned income (from employer)
  • Deduction proofs — medical, rent, education, donations, insurance, etc.
  • A Hometax login (joint/simple cert) or documents via your employer
  • (If choosing the flat rate) an application form to your employer

Step by step

  1. 1Your employer requests year-end materials — submit deduction proofs
  2. 2Check/download your data on Hometax (hometax.go.kr) “simplified” service
  3. 3Compare flat rate vs. standard rate (use the simplified estimate)
  4. 4Submit to your employer → get a refund or pay extra by the result

Tips

  • ⚠️ The flat rate forgoes most deductions/credits — compare both via the simplified service first.
  • Foreigner help: NTS foreign-taxpayer line ☎1588-0560 (English); general tax counseling ☎126.
  • ⚠️ Freelance/side/business income may require a May global income tax filing (penalties if missed).
