Did you know your employer also pays tax on your salary? It costs the employer 61,319 원 to pay you 410,000 원. In other words, every time you spend 10 원 of your hard-earned money, 5.77 원 goes to the government.
Real tax rate
50.2%
So, with you and the employer both paying tax, what used to be a 42.8% tax rate now rises to 50.2%, meaning your real tax rate is actually 7.4% higher than what it seemed at first.
Summary
If you make 852,800,000 원 a year living in South Korea, you will be taxed 364,938,427 원. That means that your net pay will be 487,861,573 원 per year, or 40,655,131 원 per month. Your average tax rate is 42.8% and your marginal tax rate is 47.9%. 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 47.88 원, hence, your net pay will only increase by 52.12 원.
Bonus Example
A 1,000 원 bonus will generate an extra 521 원 of net incomes. A 5,000 원 bonus will generate an extra 2,606 원 of net incomes.
