CRS 2.0 Incorporates Cryptographic Assets into the Global Tax “Sky Eye,” Signaling a Comprehensive Tightening of Overseas Taxation

According to Caixin, the global tax “satellite surveillance system,” CRS 2.0, is accelerating its rollout worldwide. Cryptographic assets, central bank digital currencies (CBDCs), and certain electronic money products have now been included within the scope of financial asset reporting. Hong Kong plans to implement CRS 2.0 by 2028 and simultaneously advance the Crypto-Asset Reporting Framework (CARF). In the future, cryptocurrency exchanges, brokers, and operators of crypto ATMs will be required to report cryptocurrency–fiat currency conversions, cross-cryptocurrency swaps, and domestic and cross-border transfers of cryptographic assets. Reports must precisely specify the full names of assets—for example, Bitcoin (BTC), Ethereum (ETH), and Tether (USDT)—and aggregate data by transaction dimension, including total market value, total holdings, and number of transactions. For retail payment transactions, individual transactions exceeding USD 50,000 must be reported separately. Although mainland China has not yet officially announced a timeline for implementing CRS 2.0, since 2025, tax authorities in multiple regions have begun notifying taxpayers—via phone calls and text messages—to self-report overseas income earned between 2022 and 2024 and fulfill their tax obligations accordingly. It is understood that CRS 2.0 will not only fully expose overseas-held cryptographic assets to tax oversight but may also trigger coordinated scrutiny by other regulatory bodies.
