Over the past decades, economies have become more digitally and globally integrated, which has led to a skewed taxation of cross-border transactions, which were mostly focused on the brick-and-mortar business. Since technology has advanced to the point that operations may be carried out in multiple locations simultaneously, geographic distinctions are no longer significant. Since the physical presence of the activity is highly valued under current tax legislation, multinational enterprises (MNEs) are compelled to take advantage of these developments and transfer their revenue and funds to tax haven nations in order to minimize their tax liability. The major Base erosion & profit shifting initiative, which aims to develop tools and legislation, was launched by the OECD and G20 member nations with these concerns in mind to prevent tax evasion. In order to address the issues associated with digital taxes, the OECD discussed the idea of a “Global Minimum Tax” in Pillar 2 of its BEPS Action Plan 1, which was published in December 2020. The goal of this proposal is to put an end to the three-decade-long “race to the bottom” in corporate tax rates. In this research paper, using case studies, the researchers tried to unravel the potential effects of GMT (also known as the global minimum corporation tax) on tax havens.
