The fiscal crisis of both developed and developing countries has put tax avoidance more firmly on the agenda than ever before. Although leading companies claim to be socially responsible, the focus of their CSR efforts up to now has been on environmental, labour and human rights issues and taxation has rarely featured. Indeed, many TNCs see no contradiction in espousing CSR while at the same time seeking to minimise their tax liabilities, often through aggressive tax avoidance. They are facilitated in doing so by the absence of tax issues from the CSR agenda. In the wake of the global financial crisis the climate of opinion is changing and civil society organisations are putting increasing pressure on companies over their tax contributions.
