South Korea has ended years of speculation by confirming that a long-delayed tax on virtual asset gains will finally come into force on January 1, 2027. Deputy Prime Minister Koo Yun-cheol stated during a National Assembly Finance and Economy Committee meeting on July 29 that the government currently assumes taxation will begin next year and will review the framework if necessary.
The tax structure imposes a 20% national rate on annual crypto gains exceeding KRW 2.5 million (approx. $1,900), with local taxes potentially raising the total burden to 22%. Virtual asset profits will be classified as ‘other income,’ not capital gains, and a basic annual deduction of 2.5 million won will apply. Taxpayers must calculate gains by subtracting acquisition costs from disposal proceeds, requiring detailed records from both domestic and overseas platforms.
The policy has faced three delays since its original 2022 target due to insufficient reporting infrastructure. With this confirmation, exchanges are expected to play a central role in providing transaction data for filings, though investors using multiple platforms may face reconciliation challenges. Lawmaker Kim Sang-hoon raised concerns over the absence of loss carryforward deductions, warning it could weaken domestic trading demand. The government indicated it might review this after implementation, but broader changes—such as treating crypto gains as capital gains—would require a comprehensive review of the entire capital market tax system.
As one of the largest retail crypto markets, South Korea’s move could reshape local trading activity and spur volatility as investors adapt to the new costs.
