Crypto in South Korea

South Korea established comprehensive cryptocurrency regulation through the Act on Reporting and Using Specified Financial Transaction Information, which took effect March 25, 2021. This legislation mandates all Virtual Asset Service Providers (VASPs) operating in South Korea to register with the Financial Intelligence Unit (FIU) under the Financial Services Commission (FSC). The registration requires VASPs to implement real-name bank account verification systems with domestic commercial banks, maintain anti-money laundering (AML) protocols, and obtain Information Security Management System (ISMS) certification from the Korea Internet & Security Agency (KISA). The FSC and Bank of Korea jointly oversee the market, with the FSC focusing on VASP supervision and the central bank monitoring systemic risks and developing the Digital Won CBDC. On July 19, 2023, the FSC passed the Virtual Asset User Protection Act, South Korea's first standalone crypto consumer protection law, which takes effect July 2024. This act defines virtual assets, prohibits insider trading and market manipulation, and mandates exchange segregation of customer and corporate assets.

South Korea imposes a 20% capital gains tax on annual cryptocurrency profits exceeding 2.5 million KRW (approximately $1,900), effective January 1, 2025. The tax implementation was delayed twice from its original 2022 start date due to legislative pushback and technical challenges in tracking transactions. Taxable events include profits from trading, staking, and mining activities. Residents must report crypto gains as part of their annual comprehensive income tax return filed each May. The National Tax Service (NTS) has enhanced its transaction tracking capabilities through data-sharing agreements with registered VASPs. For corporations engaged in crypto businesses, standard corporate income tax rates apply, with crypto holdings treated as intangible assets. The government has not yet finalized taxation rules for decentralized finance (DeFi) activities and non-fungible tokens (NFTs), creating uncertainty for participants in those sectors.

South Korea hosts over 5 million registered cryptocurrency users, representing nearly 10% of its 52 million population, according to FSC data from December 2023. Retail trading volume on domestic exchanges averaged $4.2 billion daily in Q1 2024, with Upbit, Bithumb, Coinone, and Korbit controlling 98% of the market. The "Kimchi Premium"—where Bitcoin prices on Korean exchanges trade 2-8% above global averages—persists due to capital controls and high retail demand. Institutional adoption accelerated in 2023 when Mirae Asset Securities launched the country's first Bitcoin futures ETF on the Hong Kong exchange. Samsung, SK Group, and LG have integrated blockchain technology into supply chain management and digital identity systems. The Bank of Korea completed the second phase of its Digital Won CBDC pilot in December 2023, testing offline payments and cross-border remittances with 100,000 simulated users.
