01 What is the Korean Year-End Tax Settlement (Yeonmal Jeongsan)?
Every January and February, all salaried wage earners in South Korea—including foreign workers—participate in the Year-End Tax Settlement (Yeonmal Jeongsan) administered by the National Tax Service (NTS).
The process recalculates your actual annual tax liability against the monthly taxes withheld from your paycheck throughout the year, resulting in either a tax refund or an additional tax payment in your February/March salary.
02 The 19% Flat Tax Rate Special Exemption for Foreign Workers
Under Article 18-2 of the Restriction of Special Taxation Act, foreign executives and employees working in Korea can elect to pay a flat 19% income tax on their gross Korean employment income instead of standard progressive tax brackets (which range from 6% to 45%).
Key Trade-off: If you choose the 19% flat rate, you forfeit all non-taxable allowances, personal exemptions, and tax credits (such as medical, education, and credit card deductions). Generally, higher-income earners (annual gross income above 80M~100M KRW) benefit substantially from the 19% flat rate, while modest earners typically save more with progressive brackets and standard deductions.

03 Top Deductible Expenses for Foreign Employees
If you file under the standard progressive tax system, maximizing the following categories through the NTS Hometax Simplified Tax Settlement Service is critical:
1) Credit, Debit & Cash Receipts: Deductions on spending exceeding 25% of your annual gross salary.
2) Medical Expenses: Out-of-pocket medical bills for yourself and eligible dependents exceeding 3% of your salary.
3) Monthly Rent (Wolse) Deduction: Cash receipts issued for monthly rent on an officetel or apartment registered under your name.
4) Insurance Premiums: National Health Insurance and qualified private health/term insurance policies.
04 Step-by-Step Filing via NTS Hometax Portal
1) Log into the official NTS Hometax portal (hometax.go.kr) using a registered Joint/Financial Certificate or PASS mobile authentication.
2) Open the 'Simplified Year-End Tax Settlement Service' (Yeonmal Jeongsan Ganso-hwa) and download your consolidated PDF tax deduction summary.
3) Submit the PDF summary along with any paper receipts not captured digitally to your company's HR/Payroll department before the annual company cutoff date.
