1. Introduction
In July 2024, the Global Forum on Transparency and Exchange of Information for Tax Purposes (the Global Forum) submitted a report titled *Bringing Tax Transparency to Crypto-Assets – An Update* to the Organisation for Economic Co-operation and Development (OECD) and the G20. The report outlines recent progress in global tax transparency initiatives for crypto-assets—specifically, the implementation of the Crypto-Asset Reporting Framework (CARF).
The OECD and G20 are leveraging CARF to promote automatic exchange of tax information globally, ensuring transparency in crypto-asset transactions and reducing risks of tax evasion and avoidance. Currently, 58 OECD member jurisdictions have announced their intention to implement CARF by the end of 2027. This article by the TaxDAO Research Team analyzes key points from the report and explores future trends in global tax information exchange.
2. Key Contents of the Report
2.1 Overview of the Report and Key Implementation Timelines for CARF
*Bringing Tax Transparency to Crypto-Assets – An Update* first introduces the background and objectives of the report, discusses definitions, uses, and development of crypto-assets, and highlights challenges related to tax transparency and information exchange. It then calls for a new global standard for crypto-assets, describing G20 efforts to advance tax transparency and detailing how OECD and G20 countries collaborated to develop CARF. Next, it explains the implementation framework of CARF, including domestic legislative frameworks, international legal frameworks, technical systems, administrative mechanisms, and standards for confidentiality and data protection. It also discusses how the Global Forum’s experience implementing the Common Reporting Standard (CRS) can inform CARF rollout. The report further outlines actions taken by the Global Forum to ensure broad adoption of CARF, concluding with an assessment of progress and emphasizing its potential benefits for tax transparency and information exchange.
The Global Forum aims to ensure that most relevant jurisdictions begin automatic exchange of information (AEOI) on crypto-assets by 2027. As of the report’s publication, 58 countries and territories—including 10 developing economies—have publicly committed to launching crypto-asset information exchanges under CARF before 2027.
To ensure timely implementation by 2027, the Global Forum has set a critical mid-term milestone: finalizing the CARF commitment process by the time of its 2024 Plenary Meeting (expected in November 2024). This means that by the end of 2024, the Global Forum will identify most participating jurisdictions and urge them to enact domestic legislation necessary to launch crypto tax information exchange by 2027. Additionally, recognizing that some developing countries may require more time for technical preparation, the CARF Working Group is considering whether limited flexibility could be granted to allow certain jurisdictions to delay implementation if needed.
2.2 How the Global Forum Will Advance CARF Implementation
2.2.1 Introduction to CARF
CARF aims to establish a unified tax information exchange framework to address regulatory gaps in crypto-asset taxation and provide tax authorities with third-party data on taxpayers’ crypto-related activities. Built upon the CRS framework, CARF was finalized by the OECD in 2023. It requires Reporting Crypto-Asset Service Providers (RCASPs)—intermediaries in the crypto space—to conduct detailed due diligence to identify reportable information and ensure accurate, timely reporting to tax authorities. CARF consists of rules and commentaries covering: 1) the scope of crypto-assets covered; 2) entities and individuals subject to data collection and reporting obligations; 3) reportable transactions and associated information; and 4) due diligence procedures to identify users and controllers of crypto-assets and their relevant tax jurisdictions for reporting and exchange purposes.
After receiving reports from RCASPs, tax authorities will use the CARF framework to exchange information internationally, enabling global oversight of crypto-assets and enhancing tax transparency.
2.2.2 Current Status of CARF Implementation
At the invitation of the G20, the Global Forum established the CARF Working Group to design the commitment process for CARF by the end of 2024, ensuring widespread global implementation. Participating countries are expected to begin exchanging information under CARF starting in 2027. The Global Forum's goal is to ensure all relevant jurisdictions commence CARF implementation within a coordinated timeframe, preventing any jurisdiction from becoming a tax avoidance "loophole."
To support CARF implementation, the Global Forum is developing essential technical infrastructure, including data reporting and exchange systems. These systems will ensure accuracy and security of information and facilitate effective cross-border cooperation.
2.2.3 Domestic Legal Implementation of CARF
There are significant synergies between CRS and CARF, which the Global Forum intends to leverage for rapid CARF deployment. To implement CARF, governments must: establish domestic legal frameworks requiring RCASPs to perform due diligence and submit reports; create international legal frameworks governing cross-border transmission of reported information; build technical infrastructure to receive RCASP data and enable international exchange; and meet expected standards for confidentiality and data protection to ensure secure handling of exchanged information.
2.3 CARF Is Essentially the Extension of CRS-Based Automatic Information Exchange into the Crypto-Asset Domain
2.3.1 Overview of the AEOI Regime
Automatic Exchange of Information (AEOI) is an international tax cooperation mechanism designed to enhance tax transparency and prevent cross-border tax evasion and avoidance. Under this regime, financial institutions are required to report financial account information of non-resident account holders, which is then automatically exchanged with the tax authorities of the account holders' home jurisdictions. The cornerstone of AEOI is the Common Reporting Standard (CRS), jointly developed by the OECD and G20 countries in 2014. CRS mandates that participating countries collect financial account information on non-resident clients through financial institutions and automatically exchange this information among themselves.
2.3.2 Extending AEOI to Crypto-Assets
As previously noted, CARF applies the CRS-based AEOI mechanism to Reporting Crypto-Asset Service Providers (RCASPs), requiring them to report crypto-asset information on their non-resident clients and automatically exchange such information with the tax authorities of those clients’ home countries. This extension enhances tax transparency in the crypto sector and helps combat tax evasion and avoidance.
2.3.3 Specific Requirements under AEOI
Key requirements under AEOI include: Account Due Diligence—financial institutions must conduct due diligence on accounts they hold to determine whether account holders are non-resident taxpayers and collect necessary information for exchange. Information Reporting—financial institutions must report relevant data to their domestic tax authorities in prescribed formats and timelines. Tax authorities then exchange this information based on international agreements. Data Protection and Privacy—countries must safeguard the security and privacy of exchanged data, preventing unauthorized disclosure. Technical Standards—for efficient and accurate information exchange, AEOI participants typically adopt uniform technical standards and data formats.
For financial institutions or taxpayers failing to comply with AEOI requirements, jurisdictions may impose various penalties, including fines to recover lost tax revenue resulting from evasion or avoidance. In serious cases, additional sanctions such as license revocation or travel restrictions may apply. However, these enforcement measures are defined by individual countries’ domestic laws and vary across jurisdictions.
3. Potential Impacts of CARF Implementation
First, enhanced tax transparency: CARF implementation will significantly improve tax transparency in the crypto-asset domain, enabling tax authorities to more accurately assess taxpayers’ crypto holdings and related income, thereby effectively curbing tax evasion and avoidance.
Second, promoting fair tax competition: By establishing a uniform global reporting standard for crypto-assets, CARF helps create a level playing field and prevents certain jurisdictions from becoming safe havens for tax evasion and avoidance.
Third, increasing government revenue: Improved tax transparency and fairer competition will help boost government revenues, providing greater funding for public services.
Fourth, strengthening public trust: By combating tax evasion and avoidance, CARF can enhance public confidence in financial systems and public institutions, contributing to financial market stability and development.
Overall, the OECD and the Global Forum aim to draw on their experience with CRS to guide CARF implementation. At the same time, the Global Forum demonstrates special attention toward developing countries—ensuring they benefit from CARF while avoiding their transformation into “tax havens.” Clearly, in response to the global and anonymous nature of crypto-assets, countries are moving toward closer collaboration on crypto-asset tax regulation. CARF is poised to enhance global tax transparency, reduce tax evasion, and strengthen institutional trust and international consensus in the years ahead.
