1. Introduction

Since the introduction of Bitcoin in 2009, the world of digital currencies has exploded. Today, more than 10,000 different cryptocurrencies exist. These digital assets, such as Bitcoin, Ethereum, and others, allow users to make transactions without needing a central authority like a bank. They also provide a level of privacy, as transactions are pseudonymous—meaning they are not directly linked to a person's identity. While this can be an advantage for users seeking privacy, it creates a huge challenge for tax authorities trying to track and tax cryptocurrency transactions.

Many governments across the globe are struggling to keep up with the rapid rise of cryptocurrencies. Tax systems, which were built to deal with traditional forms of money, now face the difficult task of incorporating these new digital assets. The decentralized nature of cryptocurrencies means that transactions happen across borders, without the control of a single nation. This has led to confusion about how to apply existing tax laws to cryptocurrency transactions, and even more confusion about how to create new, fair, and effective tax rules.

2. The Importance of Taxing Cryptocurrencies

For many governments, cryptocurrencies pose a real challenge when it comes to taxation. This is because cryptocurrencies can be used to hide financial activities, including income and capital gains. When cryptocurrencies are bought or sold, it can be difficult for tax authorities to determine the true value of the transaction. Additionally, the pseudonymous nature of cryptocurrencies makes it hard to trace who is conducting the transactions. These factors create opportunities for tax evasion and fraud, which could result in significant losses in tax revenue.

For example, wealthy individuals may hold large amounts of cryptocurrency, and because the ownership of these assets is hard to track, they might avoid paying taxes. Surveys have shown that a small number of people own a large percentage of all Bitcoin. This means that the tax burden could fall unfairly on average taxpayers, while those with large cryptocurrency holdings may evade taxes altogether.

3. Why Do We Need an International Framework for Cryptocurrency Taxation?

While some countries have begun implementing rules to tax cryptocurrencies, there is no global consensus on how to handle them. Different countries have taken different approaches, with some taxing cryptocurrencies like property or capital assets, while others treat them like currencies. These differing regulations create confusion for people who are involved in cross-border cryptocurrency transactions, and it could also lead to situations where cryptocurrency transactions fall through the cracks and avoid being taxed.

For example, if someone in India earns income from cryptocurrency trading in the United States, it is unclear which country has the right to tax that income. International tax laws and treaties, like the Double Taxation Avoidance Agreement (DTAA), don’t specifically address cryptocurrency, so there is uncertainty about which nation can claim the tax revenue.

In addition, there is a lack of clarity around how to value cryptocurrencies. Unlike traditional currencies or stocks, the value of a cryptocurrency can fluctuate wildly within a short period. This makes it hard for governments to determine how much tax a person owes when they buy or sell cryptocurrency. Without a standardized method for calculating cryptocurrency values, it becomes even harder to determine fair taxation.

4. How Should Cryptocurrencies Be Classified for Taxation?

One of the biggest questions surrounding cryptocurrency taxation is how to classify these assets. Should cryptocurrencies be treated like property, where they are taxed when they are sold for a profit? Or should they be treated as currency, subject to sales taxes and VAT (Value-Added Tax)?

In many countries, cryptocurrencies are currently treated as assets for income tax purposes. This means that any profit made from selling cryptocurrency is taxed as capital gains. However, because cryptocurrencies can also be used to buy goods and services, some governments believe they should be taxed like traditional currencies. This is especially true for sales taxes, where cryptocurrency purchases are treated the same way as purchases made with physical money.

However, the classification of cryptocurrencies remains an open issue, and clarity on this matter is essential. Without a clear classification, tax authorities may struggle to apply the correct tax rules, and individuals may face uncertainty about how to report their cryptocurrency earnings.

5. Valuation Issues in Cryptocurrency Taxation

Another significant issue with cryptocurrency taxation is how to determine the value of cryptocurrencies for tax purposes. Unlike traditional assets, where valuation is relatively straightforward, cryptocurrencies can experience extreme price volatility. For example, Bitcoin once surged to nearly $70,000 in 2021, but its value dropped to around $29,000 in 2024. This wild fluctuation means that the value of cryptocurrencies can change dramatically in a short amount of time, making it difficult for both taxpayers and tax authorities to calculate the exact amount of tax owed on a cryptocurrency transaction.

Governments need to create a clear system for valuing cryptocurrencies, particularly when they are used in transactions between countries. This is important to ensure that tax calculations are consistent and accurate, and to prevent tax evasion. Without a reliable valuation system, it becomes nearly impossible to ensure that cryptocurrency transactions are properly taxed.

6. Jurisdictional Challenges in Crypto Taxation

When it comes to taxation, jurisdiction refers to the authority of a country to tax income earned within its borders. With cryptocurrencies, however, jurisdiction becomes a complicated issue. Because cryptocurrencies are digital and decentralized, they can be traded across borders without any physical presence in a particular country. This makes it difficult to determine which country has the right to tax a cryptocurrency transaction.

For example, if someone in India buys cryptocurrency from a seller in the United States, it is unclear which country has the right to tax the transaction. If both countries claim the right to tax the same transaction, this could lead to double taxation, where the taxpayer ends up paying tax to both countries on the same income. This is a major issue in international taxation, and it highlights the need for coordinated efforts between countries to determine the proper jurisdiction for taxing cryptocurrency transactions.

7. Best Practices and Proposed Solutions

To address these issues, experts suggest that governments work together to create a uniform international tax framework for cryptocurrencies. This framework should include guidelines for classifying cryptocurrencies, valuing them, and determining the jurisdiction that has the right to tax them. International treaties and agreements, such as the DTAA, should be updated to include cryptocurrency, so that cross-border transactions are properly taxed.

Additionally, governments should work to ensure that cryptocurrency exchanges—whether centralized or decentralized—comply with tax reporting requirements. Centralized exchanges, where users trade cryptocurrencies in a more controlled environment, can be required to follow "know your customer" (KYC) regulations, which can help identify users and track their transactions. For decentralized exchanges, which operate without a central authority, governments may need to explore alternative methods for monitoring transactions and ensuring compliance with tax laws.

Finally, tax authorities must educate both taxpayers and cryptocurrency businesses about their tax obligations. Many people are still unaware of the tax rules surrounding cryptocurrencies, and without proper education, they may unintentionally evade taxes. Governments should also encourage cryptocurrency businesses to implement transparent and accountable practices, so that tax authorities can track transactions more easily.

8. Conclusion

The rapid growth of cryptocurrencies presents significant challenges for tax authorities around the world. These digital assets are decentralized, volatile, and often pseudonymous, which makes it difficult for governments to track transactions and enforce tax laws. The lack of international standards for cryptocurrency taxation has created confusion and uncertainty, both for taxpayers and tax authorities.

To address these challenges, countries need to work together to create a clear, unified international tax framework for cryptocurrencies. This framework should address issues like classification, valuation, and jurisdiction, and it should ensure that cryptocurrency transactions are taxed fairly and transparently. By collaborating on a global level, governments can prevent tax evasion, reduce fraud, and create a more stable and equitable tax system for the digital age.

As cryptocurrencies continue to evolve, it is crucial that tax laws evolve as well. With the right legal framework in place, the tax system can effectively handle cryptocurrency transactions, ensuring that taxpayers comply with the law while also allowing for innovation and growth in the digital currency space.
