Latest rates for National Pension, Health, Long-term Care, and Employment Insurance; non-taxable benefits, dependent deductions, and salary tier simulations
📌 Employee-Side Contribution Rates (2026 Standard)
South Korea's 4 major social insurances—National Pension, National Health Insurance, Long-Term Care Insurance, and Employment Insurance—form the backbone of the country's social safety net. Together with Industrial Accident Insurance (fully employer-funded), they constitute the 5 mandatory social insurances.
The amounts shown on employee paystubs reflect only the employee-side share. Employers contribute matching amounts separately, so total combined rates are effectively double the employee percentages (for Pension, Health, and Employment Insurance).

💵 Tax-Saving Strategy: Leveraging Non-Taxable Benefits
Non-taxable items are excluded from both income tax and social insurance calculations, making them the most effective lever for increasing net pay. As of January 2023, the non-taxable meal allowance was raised from KRW 100,000 to KRW 200,000 per month, dramatically boosting its tax-shelter value.
Key non-taxable items include: (1) meal allowance up to KRW 200,000/month, (2) private-vehicle allowance up to KRW 200,000/month, (3) job-related child tuition support, (4) research activity allowance up to KRW 200,000/month for researchers. When explicitly stated in the employment contract, these can reduce taxable income by over KRW 2.4 million annually.
For a worker with KRW 40 million annual salary claiming the KRW 200,000/month meal allowance: • Annual taxable income reduction: KRW 2.4 million • Income tax savings (15% bracket): ~KRW 360,000/year • Social insurance savings (9.4%): ~KRW 225,000/year • Total tax savings: ~KRW 585,000/year
📊 Take-Home Pay by Annual Salary
Based on the 2026 National Tax Service simplified withholding table and current insurance rates, we simulated monthly take-home pay across common salary brackets. Assumes the KRW 200,000 non-taxable meal allowance is applied and the worker has no dependents.

| Annual (KRW M) | Gross/mo (KRW) | Insurance (KRW) | Income+Local Tax (KRW) | Net/mo (KRW) |
|---|---|---|---|---|
| 30M | 2,500,000 | ~216,000 | ~55,000 | ~2,229,000 |
| 40M | 3,333,333 | ~291,000 | ~138,000 | ~2,904,333 |

👨👩👧👦 Maximizing Dependent Tax Deductions
The NTS simplified withholding table reduces income tax based on the number of dependents and dependent children under 20. Each dependent reduces monthly income tax by KRW 10,000–20,000, and children under 20 additionally qualify for the child tax credit (KRW 150,000/year per child).
Eligible dependents include: (1) spouse (annual income under KRW 1M), (2) parents aged 60+ (annual income under KRW 1M), (3) children under 20, (4) siblings aged 60+. A family with 4 dependents (spouse, 2 children, 1 parent) can lower monthly income tax by KRW 50,000–100,000, adding KRW 600,000–1,200,000 to annual take-home pay.
⚠️ Year-End Settlement vs. Comprehensive Income Tax
Regular employees have income tax withheld monthly per the simplified table, then reconcile with actual tax owed via the year-end settlement each February. Freelancers and business owners undergo 3.3% withholding and reconcile via the May Comprehensive Income Tax filing.
Major deduction and credit categories available during year-end settlement include: (1) credit/debit card usage deduction (amounts exceeding 25% of gross salary), (2) medical/education/donation tax credits, (3) housing subscription savings deduction, (4) pension savings and IRP tax credits (up to KRW 7M annual limit), (5) monthly rent tax credit. Effective use can yield refunds exceeding KRW 1M annually.
