Capital gains tax, simplified
This simplifies capital gains tax to (gain − 2.5M basic deduction) × rate. In reality the rate swings widely with holding period, home count, and location.
Rates here: under 1 year 70% (housing) or 50% (other); 1–2 years 60% / 40%; 2+ years the progressive 6–45%. A 10% local tax applies on top.
Excluded (important): the 1-home exemption (≤1.2B KRW), the long-term holding deduction (3+ years), and multi-home surcharges. Effective rates vary enormously per case — confirm with Hometax or a tax accountant. See the acquisition tax or gift tax calculators.
