Did you know your employer also pays tax on your salary? It costs the employer 403,995 원 to pay you 2,112,500 원. In other words, every time you spend 10 원 of your hard-earned money, 3.28 원 goes to the government.
Real tax rate
27.6%
So, with you and the employer both paying tax, what used to be a 13.7% tax rate now rises to 27.6%, meaning your real tax rate is actually 13.9% higher than what it seemed at first.
Summary
If you make 25,350,000 원 a year living in South Korea, you will be taxed 3,474,722 원. That means that your net pay will be 21,875,278 원 per year, or 1,822,940 원 per month. Your average tax rate is 13.7% and your marginal tax rate is 21.8%. 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 21.81 원, hence, your net pay will only increase by 78.19 원.
