How does the tax rate change with salary in South Korea?

South Korea’s income tax rate increases significantly as your salary rises, operating on a progressive system. For example, your effective tax rate is around 16.8% at a $50,000 salary, jumping to 21.2% at $75,000, and 26.4% at $100,000. This upward trend continues, reaching approximately 32.4% at $150,000. It's important to remember that these figures include local income tax, which is 10% of your national income tax. So, if your national tax rate is 20%, your local tax adds another 2%. The highest income tax bracket in South Korea is 45% for incomes exceeding 1 billion KRW (roughly $730,000 USD). This progressive structure means higher earners contribute a larger percentage of their income to taxes. When planning your move, calculate your net income carefully. A higher salary in South Korea doesn't always translate to proportionally more take-home pay due to this escalating tax burden.
