FROM BANKING SECRECY TO CRYPTOCURRENCY ANONYMITY: CHALLENGES TOWARD A FAIR INTERNATIONAL TAX JUSTICE

Abstract

The rapid growth of cryptocurrencies is reshaping the global financial landscape, challenging traditional systems of taxation and regulation. This article examines the complex interplay between cryptocurrency anonymity, legal frameworks, and the pursuit of international tax justice. Using normative legal research with a descriptive approach, this article examined the challenges posed by cryptocurrency adoption in taxation policies. The findings revealed that while blockchain technology enhances transparency and decentralisation, the anonymity features of digital assets create risks of tax evasion and illicit financial flows. Addressing these issues requires integrated efforts among international regulatory frameworks, such as the OECD's CARF and FATF's Travel Rule alongside domestic reforms like Indonesia's HPP Law and the EU's DAC8. Inclusive governance that empowers developing countries and the constitutional grounding of tax justice principles are essential to strike a balance between individual privacy and collective fiscal responsibility. This multi-layered approach is critical to ensuring cryptocurrencies serve as instruments of innovation rather than tools for inequality. Future research should focus on empirical assessments of compliance costs, enforcement effectiveness across borders, and the development of privacy-preserving technologies, such as zero-knowledge proofs, to enable proportional and fair regulation globally.
