Board Activities: Corporate Governance in Practice
Since the discussion, described in the case, more examples have emerged of companies and rich individuals (including some well-known media and sports personalities) adopting legal, but morally questionable, tax avoidance schemes. In a few cases, schemes have been challenged and tax has had to be paid.
Attitudes seem to be changing slowly, away from acceptance of tax avoidance, provided it is within the law, towards disapproval. Some countries now require companies to reveal profits and taxes paid country by country. But international co-operation is essential if tax havens are to become a thing of the past.
