CRS 2.0 and CARF: When Will China’s Crypto Data Join Global Tax Exchange?

Woofun AI reports that the Chinese mainland is currently absent from the OECD’s list of jurisdictions committed to implementing the Crypto Asset Reporting Framework (CARF), a critical gap identified in an article by ChandlerZ for Foresight News. This exclusion stands in contrast to the broader global shift toward transparency, as the Common Reporting Standard (CRS) 2.0 upgrades are actively being discussed in major financial media, including a detailed analysis by Caixin. The core question remains: when will the data of Chinese users begin to flow into this global tax exchange network, and what are the immediate implications for Web3 participants? The absence of China from the initial CARF roster does not imply immunity from scrutiny, but rather highlights a complex regulatory lag that may soon be addressed through domestic enforcement or future international agreements.

Caixin published an article titled "A Detailed Explanation of Taxation on Overseas Income and Insurance Proceeds" on August 5, which serves as a pivotal reference point for understanding the scope of these regulatory changes. The article explicitly notes that crypto assets will fall under the reporting scope of the upgraded Common Reporting Standard (CRS) 2.0.

For Web3 users, the direct impact is mediated through the Crypto Asset Reporting Framework (CARF), which mandates that once relevant jurisdictions pass legislation and establish exchange relationships, crypto platforms must submit annual transaction data based on the tax residency status of their users. This mechanism transforms previously opaque digital asset activities into structured, reportable financial events, fundamentally altering the privacy landscape for individuals holding overseas assets.

The shift from voluntary disclosure to mandatory automated exchange represents a significant tightening of the global tax net.

The official frameworks of the OECD are bifurcated into two distinct but complementary parts, each addressing different layers of the digital asset ecosystem. The revised CRS covers CBDCs, eligible electronic currency products, and crypto assets held indirectly through derivatives and investment entities, thereby capturing institutional and indirect exposure. In contrast, direct transactions of assets such as Bitcoin and stablecoins are mainly regulated by CARF, which targets the retail and direct trading layer. CARF applies to crypto assets that can be used for payment or investment, including cryptocurrencies, stablecoins, and derivatives issued in the form of crypto assets. This dual-track approach ensures that whether an asset is held through a traditional financial wrapper or traded directly on a decentralized platform, it falls within the purview of global tax reporting standards.

The entities subject to CARF reporting obligations are broadly defined to capture the full spectrum of crypto service providers. Exchanges, brokers, traders, and crypto ATM operators that facilitate the buying and selling of fiat currencies, currency exchanges, or asset transfers may all become services responsible for reporting crypto assets.

Notably, the framework extends its reach into decentralized finance; some decentralized trading services may also be included if there is a party that can control or significantly influence the operation of the platform. This provision is critical, as it prevents entities from evading reporting duties by merely adopting a decentralized label while maintaining centralized operational control. The definition of 'control or significantly influence' ensures that the regulatory net captures the economic reality of platform governance, not just its technical architecture.

Data collection requirements for reporting platforms are exhaustive, designed to provide tax authorities with a granular view of user activity. Trading platforms must collect users’ names, addresses, tax residency jurisdictions, taxpayer identification numbers, and dates of birth, establishing a clear link between the digital wallet and the real-world individual.

Furthermore, platforms must summarize data such as the amount of fiat purchased, sales revenue, fair value of currency exchanges, number of asset units, number of transactions, and incoming/outgoing amounts for each type of crypto asset. When platforms can identify transfer types such as airdrops, staking rewards, or loans, further classification is required. These fields record the total amount, quantity, and frequency of transactions, creating a comprehensive ledger that goes beyond simple balance reporting to capture the dynamic nature of crypto wealth generation and movement.

Self-custody wallets and non-reporting scenarios present a unique challenge to the OECD’s framework, but the rules are designed to close loopholes. The reporting obligations under CARF mainly fall on the services that facilitate transactions; individuals do not need to submit a list of their wallets to the OECD. Transfers that occur entirely between two self-custody wallets without the involvement of any reporting service will not trigger platform reporting, nor will developers who only provide wallet software without executing transactions on behalf of users bear equivalent obligations just because they release code.

However, when users transfer assets from exchanges to self-custody wallets, platforms still need to aggregate the relevant amounts and fair values of these outflows. When assets are re-deposited into reporting platforms, corresponding inflows will also be recorded. The OECD also requires service providers to retain reconciliation and reporting materials for at least five years, ensuring that historical data remains accessible for audit and verification purposes.

The data structure of CARF differs significantly from that of traditional CRS, reflecting the unique nature of digital assets. Traditional CRS typically requires reporting of year-end balances of financial accounts, interest, dividends, and total proceeds from selling financial assets, a snapshot approach that may miss intra-year volatility. In contrast, CARF is more akin to an annual transaction ledger categorized by assets, providing a continuous record of activity.

How acquisition costs, cross-year losses, and different types of income are handled remains determined by the tax laws of the user’s jurisdiction. This distinction is crucial, as it shifts the burden of calculating taxable profit from the platform to the user and their local tax authority, requiring more sophisticated accounting and compliance efforts from individuals. The OECD’s role is limited to data transmission, leaving the interpretation of tax liability to national laws.

Woofun AI data shows. Precedent from Hong Kong insurance tax cases illustrates the practical enforcement capabilities of cross-border data exchange. Cases related to taxation of Hong Kong insurance show that the core events involve the overseas insurance sector, with specific instances in Beijing and Hangzhou, Zhejiang, where taxes were imposed on proceeds from Hong Kong insurance policies. These proceeds included policy dividends and interest from prepaid premiums, with a tax rate of 20% in such cases.

After consulting tax lawyers, commercial banks, and Hong Kong insurance industry professionals, Caixin emphasized that such cases are not yet common, and there are no unified enforcement standards across different regions. Insurance products are already within the scope of CRS, and insurance contracts with cash value require reporting of the cash value or surrender value. Financial institutions also collect information such as the identity, tax residency, and taxpayer identification number of account holders, which is first sent to the tax authority in the location of the financial institution and then to the tax residency jurisdiction of the account holder.

Recent tax recovery figures and global exchange timelines highlight the accelerating pace of international cooperation. The State Taxation Administration revealed in June that in the first five months of 2026, tax authorities promoted taxpayers to pay back approximately 13 billion yuan in taxes through enhanced publicity and compliance guidance regarding overseas income. This figure covers all types of overseas income, and it is not specified how much of it comes from various types of overseas earnings, though it cannot be entirely attributed to CRS.

The significance of the Hong Kong insurance cases lies in the fact that data obtained from cross-border exchanges can already be used to identify specific targets for verification and taxation. According to the list published by the OECD as of June 23, 2026, 46 jurisdictions plan to initiate their first CARF information exchanges in 2027, 29 jurisdictions plan to start in 2028, and the United States plans to begin in 2029. Hong Kong is on the 2028 list, while the Chinese mainland has no set timeline yet, underscoring the disparity in regulatory readiness.

Hong Kong’s legislative progress and China’s future compliance path remain the key variables in this evolving landscape. The Hong Kong government promulgated draft regulations for CARF and the revised CRS on May 22 and submitted them to the Legislative Council for the first reading on June 3. As of August 7, the Hong Kong Inland Revenue Department still marks them as pending review by the Legislative Council. If approved, crypto asset service providers that meet Hong Kong’s relevant rules will start registering, identifying users’ tax residency status, and collecting transaction data from January 1, 2027, with Hong Kong planning to conduct its first exchanges in 2028.

China’s Individual Income Tax Law stipulates that resident individuals who have a domicile in China or have lived in China for 183 days or more within a tax year must declare their domestic and overseas income in accordance with the law. Whether crypto transaction information can be automatically exchanged under CARF, whether specific gains are taxable, how costs should be determined, and which income categories apply still need to be determined based on China’s current tax laws and subsequent regulations.

The outcome of the Legislative Council’s review of the draft regulations, the list of exchange partners announced by the Hong Kong Inland Revenue Department, and whether the Chinese mainland makes arrangements for implementing CARF will determine when transactions involving Chinese tax residents on overseas platforms will be included in the automatic exchange system. This marks a critical juncture for global tax transparency, where the alignment of domestic laws with international standards will define the future of digital asset taxation.
