Korea Real Estate Capital Gains Tax Calculator

Selling property in Korea? Capital gains tax (양도소득세) is often the single largest cost in a real estate transaction. The amount depends on how long you held the property, whether you lived there, how many homes you own, and whether the property is in a regulated area.

The basic formula: take your gain (selling price minus purchase price minus allowable expenses), subtract the long-term holding deduction (up to 80% for qualifying 1-house owners), subtract the annual basic deduction (₩2.5M), and apply progressive tax rates from 6% to 45%. Short-term sales — under 2 years — face punishing flat rates of 60–70%.

• Held for 2+ years
• In a regulated area: additionally lived there for 2+ years
• Selling price at or below ₩1.2 billion → fully tax-exempt
• Selling price above ₩1.2B → only the portion attributable to the excess is taxed

Long-Term Holding Deduction (LTSC)

For qualifying 1-house owners (held 3+ years, lived 2+ years):

• 4% per year held (capped at 40%)
• 4% per year resided (capped at 40%)
• Maximum deduction: 80%

For non-qualifying or multi-home owners:

• 2% per year held (capped at 30%)
• Applies only from year 3 onward

Tax-Saving Checklist

1. Hold for at least 2 years to escape heavy short-term rates
2. Live in the property for 2 years (if in a regulated area) to qualify for the exemption
3. Document all necessary expenses: renovation costs, broker commissions, acquisition taxes — these reduce your gain
4. Stage your sale timing: selling in a lower-income year reduces your progressive bracket
5. Consult on 일시적 2주택 (temporary 2-house) rules: buying a new home before selling the old one may still qualify for 1-house treatment if you sell the old home within 3 years
