What is the Financial Investment Income Tax?

The Financial Investment Income Tax (Geumtu Tax) is a system that imposes a 20% tax (25% for amounts exceeding 300M KRW) on the excess when income from financial investments such as stocks, bonds, funds, and derivatives exceeds a certain amount (50M KRW for domestic stocks).

• Implementation Date: January 1, 2026 (scheduled)
• Tax Rate: 22% ~ 27.5% including local income tax
• Basic Deduction: 50M KRW for domestic listed stocks / 2.5M KRW for others (overseas stocks, etc.)

How Should You Prepare?

1. Utilize ISA Accounts: Profits generated in ISA (Individual Savings Account) can receive tax exemption benefits from the Financial Investment Income Tax.
2. Loss Offsetting: Since taxes are calculated by combining profits and losses, you can reduce taxes by appropriately selling stocks with losses. (Year-end tax saving strategy)
3. Long-term Investment: Holding quality stocks for the long term can be advantageous in terms of tax management and fees compared to frequent trading.
