A key part of the OECD/G20 BEPS Project is addressing the tax challenges arising from the digitalisation of the economy. In October 2021, over 135 jurisdictions joined a plan to update key elements of the international tax system, which is no longer fit for purpose in a globalised and digitalised economy.
The Global Anti-Base Erosion Rules (GloBE) are a key component of this plan and ensure large multinational enterprises pay a minimum level of tax on the income arising in each of the jurisdictions where they operate.
