South Korea's income tax runs from 6% to 45% across 8 brackets, but the hidden 10% local income tax surtax pushes the true top rate to 49.5% for income above ₩1 billion (~$715,000 USD). Foreigners get a powerful option: a flat 19% + 1.9% local = 20.9% total for up to 20 years, with no deductions but massive savings for high earners above ₩130 million. The 5-year rule protects expats: if you've been in Korea less than 5 years in any 10-year period, only Korean-source income is taxed. Social security adds ~13%: National Pension 4.75% + Health Insurance 4.07%.
