South Korea confirms 22% crypto tax will apply to private wallets and foreign exchanges starting 2027

South Korea has confirmed that its upcoming 22% cryptocurrency tax, scheduled for January 1, 2027, will apply to income earned via private wallets and foreign exchanges. While the National Tax Service acknowledges the difficulty of tracking self-custodied assets, it is developing transaction-tracking software and utilizing the OECD's Crypto-Asset Reporting Framework to prevent tax evasion. Despite political opposition from the People Power Party and public petitions, the government is moving forward with implementation preparations.
