The global challenge of tax evasion presents a profound impact, leading to diminished tax revenues that are the lifeblood of a nation's seamless operations. This issue is exacerbated by the ingenious strategies employed by tax evaders, which distort economic performance benchmarks and create financial imbalances. Amidst these concerns, cryptocurrencies have emerged as a contentious subject, accused of abetting tax evasion. The covert nature of cryptocurrency transactions poses a significant hurdle for regulatory oversight and transaction recording. In response to this burgeoning concern, our comprehensive study delves into the intricate interplay between cryptocurrencies and tax evasion, utilizing annual data spanning from 2013 to 2020. With an extensive scope testing thirty two hypotheses and twelve interaction terms, our research unfurls the multifaceted dynamics at play. This study embarks by constructing a latest tax evasion index for the esteemed G-7 nations. Employing asymmetric/symmetric panel techniques, our investigation unveils a compelling revelation: cryptocurrencies exert a counteractive influence on instances of tax evasion. Furthermore, the nexus between economic performance and cryptocurrencies bears considerable sway over their correlation with tax evasion. Innovatively, our research charts the intricate relationship between tax evasion and cryptocurrencies across varying levels of economic performance. Notably, our findings underscore that Economic Freedom, Government Integrity, Government Spending, Business Freedom, Labor Freedom, Monetary Freedom, Investment Freedom, and Bureaucracy function as moderators, influencing the association between tax evasion and cryptocurrencies. These insights transcend academia, delivering significant implications to policymakers with informed guidance to devise nuanced strategies and policies.
