How to use this tool
Enter the gross prize in Korean won. Amounts up to KRW 2 million are exempt; exceeding that threshold does not mean that KRW 2 million is simply deducted before calculating the taxable amount.
Results and examples
A KRW 1 million prize produces no tax. KRW 10 million incurs KRW 2.2 million at the combined 22% rate, leaving KRW 7.8 million; the portion above KRW 300 million uses the combined 33% rate.
Limitations
- Annuity-style prizes and every other contest or award category are not covered.
- This is a withholding illustration; classification and payer-specific handling still need confirmation.
