Abstract

This paper investigated this timeless problem of tax evasion with the use of cryptocurrencies in a post-blockchain reality, in terms of legal grey zones and regulatory frameworks in various jurisdictions. Tax evaders have taken advantage of the legal grey areas, decentralized finance (DeFi) protocols, and privacy-based tools in order to hide their transactions despite the blockchain being transparent. The study used a qualitative multinational comparative research approach in which the authors have used document research and interviews with experts to examine enforcement processes in different jurisdictions including the United States, Canada, Germany, Japan, Australia and Nigeria. Conclusions were that effective statutory frameworks, high technological means of enforcement and stringent penalties were found to impact on the compliance rates positively as can be seen in Germany and Japan. Conversely, in other countries, there were high cases of non-compliance due to weakly disunity of regulation and little technological capacity, e.g., Nigeria and Canada. The introduction of DeFi became another problem since it eliminated centralized intermediaries and made the traditional tax pay reporting system more complicated. Moreover, the paper has highlighted that enforcement tactics should give due attention to enable them to balance between surveillance and privacy safeguards to keep the citizens trusty and willingly follow the law. The solution policy proposals involved integration of legal and legislative frameworks across countries globally, the integration of automated reporting solutions and investment in compliance solutions that preserve privacy. Future study on taxpayer conduct, technological breakthroughs and inter-jurisdictional cooperation to come up with resilient tax governance systems should be a matter of priority. This study added to the argument about an effective and fair establishment as an economy, as well as tax frameworks, goes digital.
