Property calculator
Estimates capital gains tax and local income tax from a Korean home’s purchase price, sale price and eligible expenses.
Estimated taxes on sale
Simplified estimate using the selected South Korean home-sale tax condition.
Actual tax depends on residence, holding period, property rights, recognized expenses, exemptions and filing facts. Confirm before filing.
How it works
For high-value one-home sales, the taxable gain is apportioned above KRW 1.2bn; selected surcharges add 20 or 30 percentage points.
Example
For an eligible one-home sale at KRW 1.3bn, the calculator treats (1.3bn−1.2bn)÷1.3bn of the gain as taxable.
Calculated from official or reliable reference material.
