The fight against tax crimes, money laundering, financing of terrorism, and bribery and corruption requires a concerted international effort through enhanced inter-agency cooperation, and exchange of information is the key goal of the G7 and the Organisation for Economic Cooperation and Development (OECD). To achieve it, they have indicated their commitment to ensuring access to beneficial ownership for tax authorities, financial intelligence units and law enforcement agencies, and to combating Common Reporting Standards (CRS) circumvention, extending an invitation to the G20 for endorsement of these initiatives. Could this be the foundation for the use of CRS, Country-by-Country and other effective beneficiary registries on matters other than tax? The OECD drive to fight tax crimes, bribery and corruption through enhanced transparency was echoed by the G7’s 2016 London Anti-Corruption Summit and ratified in the G7 Bari Declaration on Fighting Tax Crimes and Other Illicit Financial Flows. Will the G20, under Argentina’s leadership, embrace this initiative? How can corporations and high-net-worth families prepare to cope with such scrutiny?
