In fact, this is not the first large-scale verification action by tax authorities this year. As early as March 2025, tax authorities in Hubei, Shandong, Shanghai, and Zhejiang simultaneously conducted verifications, legally addressing the risks of taxpayers who failed to declare overseas income, and recovering taxes ranging from over 120,000 yuan to over 1.4 million yuan.
2.2 Sharing of International Tax Information
In February 2014, the Organization for Economic Cooperation and Development (OECD) adopted the "Standard for Automatic Exchange of Financial Account Information in Tax Matters" (AEOI). This standard consists of two parts: first, the "Model Agreement between Competent Authorities," which stipulates how tax authorities of different countries should conduct automatic exchange of financial account information in tax matters; and second, the "Common Reporting Standard" (CRS), which stipulates the relevant requirements and procedures for financial institutions to collect and report account information of foreign tax resident individuals and enterprises.
... In September 2014, China committed to implementing AEOI (Authorized Economic Operator). In September 2018, China exchanged tax-related information on non-resident financial accounts with other countries for the first time. Following the CRS framework, Chinese tax authorities can obtain key information about accounts held by resident individuals in overseas financial institutions through information exchange mechanisms, including the account holder's name, address, taxpayer identification number, year-end balance or net value, interest and dividend income earned during the calendar year, and gains from the transfer of financial assets. This information is generally reported by overseas financial institutions to their local tax authorities, and then exchanged between the tax authorities of those countries and the Chinese tax authorities. The entities obligated to report information are broad, covering various financial institutions such as banks, securities firms, insurance companies, and trust companies. Currently, CRS is widely implemented globally. China has integrated CRS rules into its national policy system and continuously increased the breadth and depth of international tax administration cooperation, and has now achieved routine automatic exchange of financial account information with more than 100 countries and regions (including the UK, Singapore, and Switzerland). International tax information sharing provides crucial data support for tax supervision, enabling Chinese tax authorities to more accurately and comprehensively identify undeclared overseas income.

Under the backdrop of the Golden Tax Project Phase IV, data-driven tax administration, and inter-departmental collaboration, tax authorities can effectively advance the investigation of overseas income, expanding from high-net-worth individuals to ordinary investors, achieving normalized supervision and precise enforcement. Tax big data has become a crucial foundation for tax authorities to implement tax supervision. Since 2021, the National Smart Tax Supervision Platform, Golden Tax Project Phase IV (hereinafter referred to as "Golden Tax Phase IV"), has been gradually implemented, achieving comprehensive and in-depth application by 2025, and has entered the planning and implementation stage of Golden Tax Phase V. Golden Tax Phase IV integrates modern technologies such as big data, cloud computing, artificial intelligence, and blockchain, supporting real-time sharing of full data from dozens of departments including taxation, banking, and industry and commerce. This means that through inter-departmental collaboration, tax authorities can integrate relevant payment data, entry and exit data, and foreign exchange payment data of Chinese residents to comprehensively assess risks and implement penetrating supervision. In practice, this also plays a crucial role in the tax authorities' acquisition of overseas tax-related information and tax risk investigation. 3. The Next Stop: The Era of Tax Transparency for Crypto Assets Has Arrived 3.1 Crypto Asset Income Is No Longer Hidden Currently, Chinese tax authorities have achieved in-depth supervision of core data such as overseas account balances and investment income through CRS information exchange and other means. Against the backdrop of global tax transparency and upgraded regulatory technology, the tax issues of cross-border income from crypto assets deserve more attention. CRS also applies to certain fund flows related to crypto assets. In August 2022, the OECD passed a series of revisions to the CRS framework, including specific electronic money products and central bank digital currencies; at the same time, it clarified that indirect investments in crypto assets through derivatives and investment instruments are also included in the scope of CRS regulation. In addition, in October 2022, the OECD launched the Crypto Asset Reporting Framework (CARF). Dubbed the "CRS of the crypto world," this framework mandates standardized reporting of tax information related to crypto asset transactions, with the aim of facilitating the automatic exchange of such information. While mainland China has not explicitly joined CARF, as a deep participant in CRS, it is expected to follow suit. Hong Kong has committed to participating in CARF exchanges starting in 2028, and exchanges registered in Hong Kong may report information on mainland residents. At that time, mainland tax authorities will find it easier to identify tax violations in this area. With the expansion of CRS and the implementation of the CARF framework, on-chain activities such as crypto transactions, DeFi yields, and NFT transactions conducted through overseas trading platforms will no longer be a tax blind spot. Through cross-border information exchange, tax authorities can track users' transaction records on compliant crypto platforms; even decentralized wallet addresses can be identified through off-chain identity information. Meanwhile, China's tax administration policies for crypto asset income are still unclear, leaving a policy buffer period for crypto asset holders to prepare for tax planning. Regarding overdue declarations or intentional concealment of overseas income, Articles 32 and 63 of the "Tax Collection and Administration Law" stipulate that taxpayers who fail to declare on time or make false declarations will face progressive penalties, including tax recovery, late payment penalties, administrative penalties, and even criminal penalties: A late payment penalty of 0.05% of the overdue tax amount will be added daily from the day following the expiration of the statutory declaration period; for tax evasion, in addition to full recovery of the tax, a fine of 50% to 5 times the amount of tax owed will be imposed; if the amount involved reaches the standard for criminal prosecution, criminal liability will be pursued. From a legal liability perspective, the cost of late payment fees and penalties incurred after the fact may far exceed the original tax payments. Crypto asset holders may consider truthfully declaring and paying taxes, provided they make reasonable tax arrangements. Specifically, improving the tax compliance system can be approached from three aspects: First, comprehensively review overseas assets and income, compile information on various financial accounts and digital asset wallets opened overseas, and establish a complete transaction record file. Second, classify various types of crypto income independently or with the help of professionals, accurately determine the nature of income and tax payment status. If taxes have already been paid overseas, accurately calculate the tax credit amount and obtain legal tax payment certificates. Third, based on the above, establish a personal tax health check mechanism and utilize professional tax tools to automate the tax compliance process. 4. Conclusion The continuous actions taken by tax authorities from the beginning to the end of this year indicate that the tax supervision of personal overseas income is developing towards greater precision, normalization, and standardization. The surge in domestic tax arrears has drawn attention, signaling the arrival of an era of global tax transparency. As an emerging asset class, crypto assets are being rapidly incorporated into the tax regulatory frameworks of various countries. For Web3 practitioners, tax planning capabilities are indispensable. Only market participants who proactively adapt to regulatory requirements and prioritize compliance can maintain a competitive edge and achieve sustainable development in the global crypto ecosystem.
