Did you know your employer also pays tax on your salary? It costs the employer 66,200 원 to pay you 346,160 원. In other words, every time you spend 10 원 of your hard-earned money, 3.15 원 goes to the government.
Real tax rate
26.5%
So, with you and the employer both paying tax, what used to be a 12.4% tax rate now rises to 26.5%, meaning your real tax rate is actually 14.1% higher than what it seemed at first.
Summary
If you make 18,000,320 원 a year living in South Korea, you will be taxed 2,230,897 원. That means that your net pay will be 15,769,423 원 per year, or 1,314,119 원 per month. Your average tax rate is 12.4% and your marginal tax rate is 14.3%. 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 14.32 원, hence, your net pay will only increase by 85.68 원.
Bonus Example
A 1,000 원 bonus will generate an extra 857 원 of net incomes. A 5,000 원 bonus will generate an extra 4,284 원 of net incomes.
