📖How to Calculate Stock Capital Gains Tax
1Enter Your Trades
Add both profitable and loss-making trades. Loss trades reduce your total taxable gain through gain-loss netting.
2Gain-Loss Netting
Gains and losses from the same tax year are netted together. Example: +$5,000 gain and -$2,000 loss = $3,000 net gain.
3Apply Deduction and Rate
Subtract the 2.5M KRW annual deduction from the net gain. The remaining amount is taxed at 22%. Tax is due the following May.
