Abstract
As crypto assets gradually enter the mainstream financial system, jurisdictions are shifting from early regulatory gaps to institutionalization in their tax treatment. The OECD's 2020 publication, "Taxing Virtual Currencies," was one of the early comprehensive studies that systematically compared the tax treatment of crypto assets across multiple jurisdictions. Subsequently, with the development of the crypto asset market, an increasing number of jurisdictions have begun clarifying relevant tax treatments through existing tax laws, special provisions, or tax guidance, leading to continuous growth in the procedural and complex nature of crypto asset taxation.
From the perspective of existing systems, the taxation of crypto assets remains primarily built upon traditional tax frameworks. Jurisdictions typically incorporate them into existing income tax, capital gains tax, corporate income tax, and indirect tax systems based on the nature of the asset and transaction activities, further specifying details through special provisions or tax guidance. The maturity of rules varies across different activities. Common activities such as buying/selling and mining entered the tax system earlier, while on-chain native activities like DeFi and NFT involve more complex asset exchanges, income recognition, and transaction structures, with related tax rules still relatively lagging.
Meanwhile, significant differences exist in tax treatment and effective tax burdens across jurisdictions. Crypto assets may involve direct taxes, indirect taxes, and property-related taxes simultaneously. Different holding periods, transaction methods, income nature, and taxpayer status can also alter tax outcomes. Therefore, the global crypto asset tax system is gradually shifting from the question of whether to tax towards more refined classification and treatment of different assets, transactions, and economic activities.
Crypto Tax Rules Continue to Expand
Crypto assets entered the tax system relatively late. The OECD's 2020 report, "Taxing Virtual Currencies: An Overview of Tax Treatments and Emerging Tax Policy Issues," conducted a systematic comparison of the income tax, consumption tax, and property tax implications of crypto assets based on the participation of over 50 jurisdictions. It was the first comprehensive study of its kind covering such a broad range of jurisdictions at the time. The OECD noted that research into the tax implications of crypto assets in various regions was still in its early stages, with no consistent treatment established on fundamental issues such as asset nature, taxable events, income classification, and valuation.
Since then, the coverage of crypto asset tax rules has continued to expand. PwC data from 2021 showed that jurisdictions with tax guidance for crypto assets increased from 7 in 2014 to 29 in 2021, more than quadrupling in seven years. By 2025, this number had further increased to 43. While coverage continued to expand, existing systems also accelerated in refinement and extension.
Existing Tax Regimes Still Dominate, with Diverging Rule Maturity
Currently, the taxation of crypto assets still primarily relies on existing tax systems. The U.S. continues to treat digital assets as property subject to general tax rules, while Australia's 2025 tax review concluded that existing tax laws already cover digital asset transactions. A European Commission comparison across 27 member states showed that most member states handle crypto assets mainly within the existing tax framework, with corporate crypto business income uniformly included in corporate income tax.
Tax rule coverage for different crypto activities is uneven. In PwC's 2021 survey of over 40 jurisdictions, the proportions having tax guidance for individual and corporate crypto asset buying/selling were 86% and 83% respectively, 72% for mining, but only 31% for staking, and just 7% each for DeFi and NFT. By 2025, this disparity persisted: Germany's latest income tax guidance for crypto assets covers many common transaction types, but NFT and liquidity mining are still not included; Australia also lists DAOs, DeFi, GameFi, and NFT as areas requiring further study. Overall, activities more easily mapped to traditional assets, income, and financial transactions are more readily absorbed by existing tax laws; the more complex the on-chain structure, the more tax rules tend to lag.
Significant Tax Burden Differences Across Jurisdictions
Crypto asset taxation is highly complex. The tax burden is not determined by a single rate but may involve multiple tax types such as personal income tax, capital gains tax, corporate income tax, value-added tax or sales tax, property tax, and inheritance tax. Specific application also depends on the nature of the transaction. For example, buying/selling, payments, mining, staking, and business operations may respectively constitute asset disposal, investment income, or business income, subject to different tax calculation rules.
Therefore, so-called "crypto tax friendliness" is a comprehensive judgment based on individual needs and jurisdictional rules. Beyond nominal tax rates, factors such as tax residency status, individual or corporate entity status, income classification, holding period, tax-exempt thresholds, and long-term holding incentives must be considered. The same jurisdiction may be friendly towards long-term personal investment but apply a completely different tax burden for high-frequency trading, mining, or corporate operations.
The figure below compares representative tax rates in major jurisdictions, considering common scenarios such as personal investment disposal, corporate income, staking rewards, and mining rewards. The comparison also factors in economic scale, crypto asset market activity, and regional representativeness, revealing significant differences in actual tax burdens. Given the complexity and continuous evolution of crypto asset tax rules globally, certain applicable conditions and special rules have been simplified in the figure for easier visual comparison.
