Tax behaviour is now a major feature of corporate reputation with instant communication putting intense pressure on international companies to publish information on how they meet their tax obligations and manage tax risks.

Fiscal  transparency and fairness are key concepts not just for enterprises and individuals, but for the government and financial institutions who compete to promote and attract international trade and investment. The G20/OECD project to tackle base erosion and profit shifting – BEPS - has brought together over 135 countries in a collaborative effort to combat tax avoidance, with a key focus on digitalisation.
