As of January 1, 2026, the Organisation for Economic Co-operation and Development has officially launched the first global data collection phase of its Crypto-Asset Reporting Framework (CARF), marking a major step toward standardized international tax oversight of digital assets.
The framework requires crypto-asset service providers (CASPs) in participating jurisdictions to begin collecting detailed user transaction and identity data, laying the groundwork for cross-border tax information sharing starting in 2027.
From the start of 2026, regulated crypto platforms operating in participating countries must collect and store expanded customer information. This includes tax residency declarations and Tax Identification Numbers (TINs), alongside transaction records covering crypto-to-crypto trades, crypto-to-fiat conversions, and certain high-value transfers.
The 2026 calendar year will serve as the baseline reporting period. Although tax authorities will not begin automatically exchanging data until 2027, all information gathered during 2026 will form the first comprehensive dataset under the new global standard.
The initial rollout includes 48 jurisdictions, covering all European Union member states through the DAC8 directive, as well as the United Kingdom, Japan, South Korea, and Singapore.
For individual investors, the practical impact is increased disclosure requirements on regulated platforms. Users must provide accurate self-certifications of tax residency, which will later be used by national tax authorities to match reported crypto activity with domestic tax filings.
Once international data exchanges begin in 2027, tax agencies will be able to receive standardized information on users’ crypto activity across borders, significantly reducing the ability to obscure offshore digital asset transactions.
Crypto exchanges, brokers, and custodial wallet providers must integrate CARF requirements into their existing KYC and AML systems. Failure to comply can result in material penalties. In the United Kingdom, for example, fines of up to £300 per customer apply if required information is not properly collected.
The reporting scope is broad. CARF applies not only to major cryptocurrencies such as Bitcoin and Ethereum, but also to stablecoins, tokenized securities, and certain NFTs that function as payment or investment instruments.
The United States is not a signatory to the OECD’s multilateral CARF agreement. Instead, it is rolling out a parallel domestic framework. Beginning in 2026, U.S. brokers will report gross proceeds from digital asset transactions using Form 1099-DA, covering activity that occurred during 2025.
Meanwhile, a second wave of 27 jurisdictions, including Australia, Canada, Switzerland, and Hong Kong, is scheduled to begin data collection on January 1, 2027, with their first automatic information exchanges planned for 2028.
The start of CARF data collection represents a structural shift in how governments monitor digital assets. While immediate enforcement consequences may not be felt until reporting exchanges begin, 2026 marks the point at which crypto activity on regulated platforms becomes fully integrated into the global tax transparency system.
For both investors and businesses, the era of fragmented, jurisdiction-by-jurisdiction reporting is giving way to a coordinated international framework with long-term implications for compliance, privacy, and cross-border crypto usage.
