June 07, 2025

In today’s digital economy, the movement of cross-chain assets is becoming increasingly frequent, encompassing blockchain technology, cryptocurrencies, and various decentralized finance (DeFi) products. The trading of these cross-chain assets not only provides users with diverse investment opportunities but also introduces complexities in tax processing. With the rapid development of blockchain technology, tax authorities in many countries and regions have begun to focus on the tax issues related to cross-chain assets, striving to promote technological innovation while ensuring the proper collection of taxes. The following discussion will explore this topic from the perspectives of policy background, tax processing challenges, specific case analysis, and matters that taxpayers should pay attention to.

I. Definition and Development of Cross-Chain Assets

Cross-chain assets refer to digital assets that circulate or are exchanged between different blockchains. For example, the representation of Bitcoin on the Ethereum network, or under cross-chain bridge technology, assets can be exchanged and used across different chains. Their emergence has promoted the liquidity of digital assets and provided investors with more options.

With the rise of emerging applications such as DeFi and NFTs, the environment for using cross-chain assets has become increasingly complex. Various protocols and platforms are rapidly emerging, and users are often unclear about their tax responsibilities when conducting cross-chain transactions. This makes understanding and mastering the tax treatment of cross-chain assets particularly important.

2. Tax Policy Background

  • International tax rules
  • International tax organizations such as the Organization for Economic Cooperation and Development (OECD) are working on tax governance for the digital economy. Under the guidance of the OECD, countries are considering how to establish appropriate tax frameworks for digital assets. For example, the "global tax agreement" proposed by the OECD aims to address issues of base erosion and profit shifting brought about by the digital economy.

  • Differences in national policies
  • There are significant differences in the tax treatment of cross-chain assets among various countries. For example, the U.S. Internal Revenue Service (IRS) treats cryptocurrencies as property and taxes their capital gains. In some European countries, however, income from digital asset transactions may be regarded as business income and subject to different tax rates. Additionally, some countries have not yet introduced relevant policies, resulting in uncertainty in the tax treatment of cross-chain assets.

    3. Difficulties in Tax Treatment of Cross-Chain Assets

  • Determination of the Nature of Assets
  • The nature of cross-chain assets may affect their tax treatment. Assets may exhibit different characteristics on different chains; for example, the tax treatment of stablecoins may differ from that of traditional cryptocurrencies. Therefore, determining the classification of the asset is crucial for subsequent tax processing.

  • The complexity of the trading model
  • Cross-chain transactions involve various trading models, including swaps, lending, staking, and others. How these transaction types are classified for tax purposes, as well as how the resulting gains are calculated, are both complex and challenging issues.

  • The reporting mechanism is inadequate.
  • Currently, most tax authorities have not established a comprehensive reporting mechanism for cross-chain asset transactions. The lack of transparency and standardized reporting methods makes it easy for taxpayers to overlook or misreport their tax obligations, increasing tax risks.

    4. Tax Obligations for Cross-Chain Assets

  • Obligations of Individual Taxpayers
  • For individual investors, the buying and selling of cross-chain assets and the resulting profits are generally considered capital gains. Investors need to accurately report their earnings and pay the corresponding taxes in accordance with the laws and regulations of their respective countries.

  • Responsibilities of Corporate Taxpayers
  • As participants in cross-chain assets, enterprises must comply with stricter tax regulations. When conducting cross-chain transactions, enterprises need to consider multiple taxes such as income tax and value-added tax, which brings more challenges to tax planning.

    4. Specific Case Analysis

    Case 1: Capital Gains of Individual Investors

    Zhang traded Bitcoin for Ethereum on a certain cross-chain trading platform. When Zhang purchased the Bitcoin, the price was 50,000 yuan, and later he sold it at a price of 70,000 yuan, theoretically generating a capital gain of 20,000 yuan. According to local regulations, Zhang is required to pay taxes on this 20,000 yuan capital gain.

    Case 2: Enterprise Lending on DeFi Platforms

    A company uses its held crypto assets for lending on DeFi platforms. During the loan period, although the company does not actually sell the assets, it should be noted that the interest income generated from lending is also subject to taxation. This portion of income may be recognized as the company's operating income and must be taxed according to the applicable corporate income tax.

    VI. Matters to Which Taxpayers Should Pay Attention

  • Accurately record transactions
  • Taxpayers are required to maintain complete transaction records, including the transaction time, counterparty, transaction amount, and specific assets involved in the transaction. This information not only helps in calculating tax liabilities but also provides effective evidence during audits.

  • Stay informed about policy changes in a timely manner.
  • Given that policies related to cross-chain assets are still evolving rapidly, taxpayers should regularly monitor changes in relevant laws and regulations to ensure the legality and compliance of their tax treatment.

  • Professional consultation
  • The tax treatment of cross-chain assets is relatively complex. It is recommended that taxpayers seek advice from professional tax consultants to obtain targeted guidance and ensure that potential legal risks are minimized during the tax processing.

    5. Conclusion

    The tax treatment of cross-chain assets is a complex and important topic. In the rapidly evolving field of digital assets, tax policies are also continuously developing. Investors, businesses, and relevant practitioners must take tax issues in cross-chain asset transactions seriously, and fulfill their tax obligations in a reasonable and compliant manner through accurate record-keeping, timely policy updates, and professional advice.
