치즈감자Reading a Korean Pay Slip: Base Salary, Overtime, and Deductions Explained
Receiving your monthly pay slip in South Korea can feel overwhelming when confronted with a dense matrix of Korean payroll abbreviations, insurance subtractions, and tax withholdings. Yet understanding every line item on this document is essential for verifying that your employer has paid you accurately according to statutory labor regulations.
Under Article 48, Paragraph 2 of the Labor Standards Act (근로기준법), all employers throughout South Korea must provide an itemized wage statement (급여명세서) every payday, whether via printed paper, email, or mobile messaging. Failure to provide an itemized statement carries administrative fines up to 5,000,000 KRW. Use the annotated breakdown below to audit your own monthly pay.
| 사원명 / 지급일 | MINH / 2026년 10월 10일 |
|---|---|
| 1기본급 (Base Salary) | 2,150,000원 |
| 2연장근로수당 (Overtime) | 231,340원 |
| 3야간·휴일근로수당 (Night / Holiday) | 154,230원 |
| 4국민연금 (National Pension) | 96,750원 |
| 5건강보험 및 요양보험 | 86,410원 |
| 고용보험 (Employment) | 19,350원 |
| 6소득세 및 지방소득세 | 42,500원 |
| 7차인지급액 (Net Pay) | 2,290,560원 |
- 1기본급 (Base Salary) — Contractual base wage for 209 statutory hours. Divide this figure by 209 to determine your ordinary hourly wage (통상시급), which sets all overtime rates.
- 2연장근로수당 (Overtime) — Overtime compensation. Statutory formula: ordinary hourly wage multiplied by overtime hours worked multiplied by the 1.5 premium rate.
- 3야간·휴일근로수당 (Night / Holiday) — Special shift premiums. Work performed between 22:00 and 06:00, or on scheduled rest days, receives an additional 50 percent hourly premium.
- 4국민연금 (National Pension) — Statutory pension deduction (4.5% employee share, matched by 4.5% employer share). Foreign workers from qualifying countries can claim this back upon final departure.
- 5건강보험 및 요양보험 — National Health Insurance (3.545% employee share) combined with Long-term Care Insurance for the elderly. Both are shared equally with your employer.
- 6소득세 및 지방소득세 — Withholding tax deducted at source using national tax withholding brackets, combined with a 10 percent local resident income surtax.
- 7차인지급액 (Net Pay) — Net take-home pay. Total gross earnings minus total deductions. This exact sum must match the actual deposit into your bank account.
Gross earnings: Calculating base wage and overtime premiums
Your total compensation begins with gross earnings (지급총액), which combines contractual base pay with performance or statutory allowances. For full-time employees working 40 hours per week, your base salary covers 209 standard hours per month, incorporating the mandatory weekly paid holiday (주휴수당). Dividing your base pay by 209 gives your ordinary hourly wage (통상시급).
This ordinary hourly wage is the mathematical basis for all statutory overtime allowances. When you work beyond 8 hours a day, the law guarantees time-and-a-half (150 percent). If overtime takes place late at night between 22:00 and 06:00, or during a public holiday, premiums stack together. For instance, working 4 overtime hours at night entitles you to base overtime (150%) plus night differential (50%), totaling 200 percent of your base hourly rate.
The statutory minimum wage sanity check
Every year, the Korean government announces a nationwide statutory minimum hourly wage (최저시급). To confirm that your monthly base salary is legally compliant, calculate your base wage divided by 209 contractual hours. If that resulting hourly number falls even one won below the prevailing minimum wage rate, your contract violates the Minimum Wage Act (최저임금법). Fixed overtime allowances or discretionary bonuses cannot be bundled together to mask a sub-minimum base salary.
The four social insurances: Who pays what?
South Korea's comprehensive social safety net (4대 사회보험) is funded through shared contributions between employees and employers. On your pay slip, deductions appear under the deduction total (공제총액). National Pension (국민연금) charges 9 percent of gross income, with 4.5 percent deducted from your wage and the remaining 4.5 percent paid directly by the employer. Foreign nationals on E-9, E-7, or F visas should review bilateral social security treaties, as many nationalities can claim a lump-sum refund (반환일시금) with accrued interest upon permanently departing South Korea.
National Health Insurance (국민건강보험) operates similarly, split evenly at roughly 3.5 percent each for worker and firm (the rate is reset every year), plus a small surcharge for long-term elderly care. Employment Insurance (고용보험) finances unemployment benefits and vocational training; employees contribute 0.9 percent. Crucially, Industrial Accident Compensation Insurance (산재보험) never appears as a deduction on your pay slip because it is funded 100 percent by the employer. If an employer ever deducts accident insurance from your wage, that deduction is strictly illegal.
Income tax withholding versus year-end tax settlement
Every month, your company withholds estimated national income tax (소득세) and local income tax (지방소득세) using the National Tax Service simplified tax withholding table (근로소득 간이세액표). Because this monthly figure is only an estimate based on income brackets and reported family dependents, it is reconciled every February during the Year-End Tax Settlement (연말정산).
During tax settlement, you submit receipts for qualifying medical expenditures, debit and credit card spending, public transportation costs, education expenses, and monthly rent payments. If too much tax was deducted across the prior year, you will receive a handsome tax refund on your February or March pay slip. Conversely, if insufficient tax was withheld, a secondary tax settlement deduction will be applied.
Auditing discrepancies and bank transfer validation
Always compare your pay slip with your personal work attendance records and your bank account transaction statement. Check whether all approved overtime hours, weekend shifts, and meal subsidies were included in the gross calculation. Article 43 of the Labor Standards Act mandates that wages must be paid in full, in legal currency, directly to the worker's own bank account on a fixed date every month.
Employers are strictly forbidden from paying through third parties, retaining wages as forced savings, or applying arbitrary deductions labeled as administrative fees or accommodation costs without prior written consent. If you notice any discrepancy between your pay slip total and the money entering your bank account, immediately request clarification from the accounting department in writing.
