The number on your employment contract and the amount that actually hits your bank account are very different. After deducting social insurance and income tax plus local income tax, a 50 million won salary yields only about 3.4 million won per month in take-home pay. This guide compares take-home pay across salary brackets using 2026 rates and covers strategies to maximize your net income.

Gross Salary vs Take-Home Pay
Your gross annual salary is the total compensation your employer agrees to pay over one year. After mandatory deductions are subtracted, the remaining amount deposited into your account is your take-home pay.
National Pension, Health Insurance, Long-term Care Insurance, Employment Insurance — employees pay half.
Progressive rates from 6% to 45% are applied based on taxable income brackets.
An additional 10% of income tax is levied separately.
For example, an employee earning 50 million won annually receives about 4.17 million won monthly. After roughly 370,000 won in social insurance and 400,000 won in income/local tax, the take-home pay is approximately 3.4 million won.
