Tax evasion often goes hand in hand with other serious economic crimes, such as bribery, corruption or money laundering. These crimes are increasingly international and rely on hiding the financial trail. As a result, OECD’s efforts in the tax area have concentrated on increasing transparency, e.g. by ending bank secrecy and strengthening access to beneficial ownership information, and promoting cross-border as well as inter-agency cooperation. Over 150 jurisdictions are working together to implement the tax transparency standards and we are breaking down the silos between law enforcement agencies through the Oslo Dialogue initiative.
