Did you know your employer also pays tax on your salary? It costs the employer 21,323 원 to pay you 111,500 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 1,338,000 원 a year living in South Korea, you will be taxed 143,014 원. That means that your net pay will be 1,194,986 원 per year, or 99,582 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.
