South Korea Advances CARF: New Developments in Tax Information Exchange for Encryption Assets

Written by: FinTax

News Overview

According to the latest report from cryptonews, the South Korean government will initiate practical procedures to implement the “Crypto-Asset Reporting Framework (CARF)” led by the OECD, sharing trading information of foreign investors on local exchanges such as Upbit and Bithumb with other countries.

This move is part of South Korea's fulfillment of its international commitments. As early as November 2023, South Korea joined a group of 48 countries, committing to jointly implement an international digital asset reporting standard called the “Crypto Asset Reporting Framework.” This framework aims to facilitate the automatic exchange of tax information related to cryptocurrency transactions in a standardized manner. However, South Korea's initiative is not an isolated case but part of a global trend to enhance tax transparency. Tax authorities in multiple countries, including the UK, Germany, and Japan, are actively promoting similar policies to prevent offshore tax evasion.

The report also clarified the timeline for the plan: the entire information sharing system will officially launch in 2027, but the collection of transaction records will begin in 2026.

FinTax Viewpoint

As cryptocurrency assets evolve into an indispensable component of the global financial system, their inherent characteristics of decentralization, anonymity, and cross-border flow pose unprecedented challenges to the global tax system. The current international tax information exchange standard, known as the “Common Reporting Standard” (CRS), was primarily designed to address financial accounts held by traditional financial institutions such as banks, and it inadequately covers transactions conducted through cryptocurrency service providers, thereby creating a significant potential tax gap.

In response to this global tax compliance risk, the OECD has taken the lead in formulating and launching the CARF. The fundamental purpose of this framework is to incorporate the cryptocurrency ecosystem into the global tax transparency trajectory by establishing a standardized automatic exchange mechanism for tax-related information, effectively combating international tax evasion using cryptocurrencies, and maintaining the integrity and fairness of tax bases in various countries.

The operational logic of CARF assigns the core reporting obligations to key intermediary nodes within the ecosystem - “Crypto-Asset Service Providers” (CASPs). This is a broad definition aimed at encompassing any individual or entity that provides cryptocurrency trading services to clients as part of their business, including but not limited to centralized cryptocurrency exchanges, cryptocurrency brokers, and market makers. To fulfill reporting obligations, these service providers must implement a strict set of due diligence procedures to accurately identify their customers' identity information and tax residency.

After completing customer identity verification, CARF requires service providers to report a comprehensive range of transaction information and summarize it annually by category of cryptocurrency assets. For each type of transaction, service providers must report the total acquisition amount, total disposal amount, and the number of transactions within the year. Once this information is collected, it will be automatically exchanged through the existing international legal framework. Specifically, service providers located in Country A will report the identities of tax residents of Country B and their transaction data to the tax authorities of Country A, which will then automatically and in bulk transmit this information to the tax authorities of Country B annually, thus achieving a global information closed loop.

The South Korean government's active adoption and swift action on CARF is significant far beyond merely a country fulfilling its international commitments. As one of the largest markets in the world in terms of cryptocurrency trading volume and user participation, South Korea's position serves as a strong barometer. The actions taken by South Korea send a clear signal to global cryptocurrency service providers: compliance is no longer optional but a necessity for survival. This is especially true for large exchanges operating globally, as meeting the regulatory requirements of a major market means they must accelerate the establishment of a compliance system that can adapt to global standards.

For individual investors caught in this wave of transformation, the most fundamental change is that the past “gray area” of tax planning or even evasion using information opacity and barriers of cross-border jurisdiction is being completely eliminated. The assumption that “cryptographic assets are unknown” no longer exists. Tax authorities can now hold direct and conclusive data through CARF to cross-check with taxpayers' annual declarations, significantly enhancing the efficiency of tax audits.

Overall, South Korea's implementation of the CARF rules not only reflects the inevitable trend of global tax compliance for crypto assets, but also further indicates that compliance is a threshold that participants in the crypto market must cross. At the same time, it further reminds individual investors to discard the past belief that crypto assets do not require tax payments, and to pay attention to the tax policies regarding crypto assets in their respective countries. Under the compliance framework, they should hold crypto assets in order to avoid tax risks and maximize long-term returns.
