The capital-gains page preserves the KRW 2.5 million annual basic deduction, real-estate long-term holding deduction, asset-type separate rates, and 10 percent local income tax. This English calculator calls the Korean page feature lib directly. The UI is translated, but the numbers come from the same pure calculation path instead of a generic value-times-rate stub.

Capital gains income tax calculator

This English guide translates the Korean capital-gains income tax page and preserves transfer income, acquisition cost, necessary expenses, annual deduction, holding-period deduction, asset-type rate, and local tax.

Transfer income and basic deduction

Transfer income is calculated as transfer price minus acquisition price and necessary expenses. The Korean capital-gains utility then applies the KRW 2.5 million capital-gains basic deduction before taxable income is calculated.

For real estate, holding period can also produce a long-term holding deduction. For stocks and other assets, the applicable rate can differ by asset type, major-shareholder status, and whether separate or comprehensive taxation is selected.

Separate versus comprehensive taxation

The calculator preserves the separate-tax path for asset-specific rates and the comprehensive-tax path that applies progressive brackets after deductions. Local income tax is added at 10 percent of income tax.

One-house exemptions, listed-stock treatment, farmland exemptions, and other statutory exceptions can change the answer. The English guide keeps those issues visible so users do not treat the calculator result as a universal transfer-tax answer.

How to prepare inputs

Users should collect purchase contract, sale contract, registration costs, broker fees, capital-improvement evidence, acquisition tax receipts, and other necessary expense evidence before relying on the output.

The calculator is most useful for scenario planning: sale timing, holding-period change, deductible expense evidence, and whether separate or comprehensive treatment creates a lower tax result.
