South Korea will implement the OECD’s Crypto-Asset Reporting Framework (CARF), collecting domestic exchange data on non-resident crypto traders and receiving residents’ records from overseas platforms, which will be reported to the National Tax Service (NTS). Formal automatic information exchange begins in 2027, but transactions from next year will be covered. Overseas crypto account holders with balances above KRW 500 million must self-report. Authorities reported KRW 11.1 trillion in overseas crypto disclosures this year. Officials added the measure follows international agreements and is separate from domestic crypto taxation, which is delayed until 2027.
