South Korea will align with the OECD’s new global standards for crypto transaction reporting, moving to implement the Crypto-Asset Reporting Framework (CARF) in the coming years.
Data sharing to begin by 2027
The Ministry of Economy and Finance confirmed that South Korea will participate in CARF, which mandates automatic information exchange on cross-border cryptocurrency transactions. According to reports, Korean exchanges will be required to share data on foreign users with their respective tax authorities, while transactions by Korean residents on offshore platforms will be disclosed to South Korea’s National Tax Service. The phased rollout is expected to begin with data collection in 2026, followed by international information exchange in 2027.
The decision places South Korea among a growing number of jurisdictions that have agreed to adopt the OECD framework. Policymakers view the move as essential to combating tax evasion, curbing illicit flows, and enhancing global regulatory coordination in the fast-evolving digital asset sector.
Part of a broader global initiative
The OECD developed CARF in response to mounting concerns from governments worldwide over the opacity of digital asset transactions. Unlike traditional financial institutions, which already fall under the Common Reporting Standard (CRS) for automatic tax information exchange, cryptocurrency exchanges and wallet providers have operated with limited cross-border disclosure obligations. CARF aims to close that gap by imposing similar reporting standards on digital asset intermediaries.
South Korea’s participation signals its commitment to aligning with global norms, reinforcing measures already underway at the domestic level. The country has steadily introduced tighter oversight in the sector, including the licensing of crypto exchanges, mandatory real-name trading accounts, and the impending introduction of capital gains taxes on digital asset transactions. By joining CARF, Seoul is preparing to synchronize its domestic regulations with international frameworks, ensuring that Korean regulators have access to critical data about their citizens’ offshore activities.
For local exchanges such as Upbit, Bithumb, Coinone, and Korbit, the new requirements will mean significant compliance upgrades. These platforms will be expected to track, verify, and report detailed information on foreign users’ transactions to Korean authorities, which will then be shared with other participating jurisdictions. Conversely, South Korea will also gain access to information about its citizens’ activity on overseas platforms, a step expected to broaden the tax base and improve enforcement.
Industry observers note that while the transition may increase operational costs for exchanges, it could ultimately boost investor confidence by enhancing transparency and aligning Korea’s regulatory standards with those of leading global markets. Some analysts also highlight that participation in CARF may support Korea’s ambition to strengthen its role as a fintech and blockchain innovation hub, as compliance with international norms is increasingly seen as a prerequisite for institutional adoption.
The implementation timeline allows exchanges and regulators some breathing room, with full data sharing not scheduled until 2027. However, experts warn that preparation will need to begin immediately, given the technological and procedural upgrades required for compliance. The OECD has already released technical guidance, including updated XML schema standards, to assist jurisdictions and industry participants in preparing for the rollout.
As South Korea takes steps to integrate into the CARF system, the move underscores a broader global trend: digital assets are no longer operating in regulatory isolation. Instead, they are being brought under the same international frameworks that govern traditional finance, with implications that will reshape the industry for years to come.
