Tommaso Faccio The French car-service company Heetch recently displayed an advertising campaign on the streets of Paris (see photo), which proudly affirmed its presence in many French cities but not in Luxembourg—a clear allusion to the tax headquarters of some of its competitors. The fact that ‘paying taxes in France’ has become a commercial argument shows that the issue of corporate avoidance is rising up the public agenda in many countries. Recent research by Gabriel Zucman shows that European Union tax havens—Luxembourg, Belgium, Cyprus, the Netherlands, Malta and Ireland—are responsible for around 90 per cent of all tax avoidance within the union. The proportion of corporate tax forgone amounts to 15, 22 and 26 per cent in Italy, France and Germany respectively.
