Did you know your employer also pays tax on your salary? It costs the employer 67,040 원 to pay you 384,000 원. In other words, every time you spend 10 원 of your hard-earned money, 3.99 원 goes to the government.
Real tax rate
33.9%
So, with you and the employer both paying tax, what used to be a 22.4% tax rate now rises to 33.9%, meaning your real tax rate is actually 11.5% higher than what it seemed at first.
Summary
If you make 99,840,000 원 a year living in South Korea, you will be taxed 22,369,435 원. That means that your net pay will be 77,470,565 원 per year, or 6,455,880 원 per month. Your average tax rate is 22.4% and your marginal tax rate is 29.0%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 원 in your salary will be taxed 29 원, hence, your net pay will only increase by 71 원.
Bonus Example
A 1,000 원 bonus will generate an extra 710 원 of net incomes. A 5,000 원 bonus will generate an extra 3,550 원 of net incomes.
