Did you know your employer also pays tax on your salary? It costs the employer 9.56 원 to pay you 50 원. In other words, every time you spend 10 원 of your hard-earned money, 2.98 원 goes to the government.
Real tax rate
25.0%
So, with you and the employer both paying tax, what used to be a 10.7% tax rate now rises to 25.0%, meaning your real tax rate is actually 14.3% higher than what it seemed at first.
Summary
If you make 13,000 원 a year living in South Korea, you will be taxed 1,390 원. That means that your net pay will be 11,610 원 per year, or 968 원 per month. Your average tax rate is 10.7% and your marginal tax rate is 10.7%. 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 10.69 원, hence, your net pay will only increase by 89.31 원.
Bonus Example
A 1,000 원 bonus will generate an extra 893 원 of net incomes. A 5,000 원 bonus will generate an extra 4,466 원 of net incomes.
