Tax transparency continues to be a key focus of governments and the public, as demonstrated by the continuing media coverage surrounding data leaks in recent years. These data leaks have also shown that tax evasion is not an isolated financial crime, but is commonly linked to a broad set of activities, including money laundering and corruption, that negatively impact societies. The leaks revealed the use of companies and trusts to hide the beneficial owners of assets and highlighted the key role that transparency of ownership information can play in preventing tax evasion, corruption and other related activities.  International standards require minimum levels of transparency concerning the beneficial owners of companies, trusts and other legal arrangements for tax as well as anti-money laundering purposes. It is more difficult for tax evaders and other lawbreakers to hide their criminal activities and proceeds of crime in jurisdictions where these standards are fully implemented.  This toolkit contains policy considerations that Global Forum member jurisdictions can use to implement legal and supervisory frameworks to identify and collect beneficial ownership information, which is now a requirement of the international standards.
