Every year, countries lose $492bn in tax a year to multinational corporations and wealthy individuals using tax havens to underpay tax, says the Tax Justice Network. Two-thirds of these losses, or $347.6bn, are attributable to tomultinational corporations shifting profit offshore to underpay tax. The remaining $144.8bn is due to “wealthy individuals hiding their wealth offshore.”

Almost half of these losses come from eight countries that oppose the adoption of a tax treaty under the aegis of the UN: Australia, Canada, Israel, Japan, New Zealand, South Korea, the United Kingdom and the United States, says the report. These “harmful eight,” according to the Tax Justice Network, cost the world $212bn in lost tax revenue every year.
