A new report from Oxfam and the Tax Justice Network estimates that $289 million in tax revenue was ripped out of developing countries in Africa in one year by mining companies exploiting tax concessions or loopholes. The report does not accuse any companies of illegal activity, but calls on mining companies to pay their “fair share” of tax by aligning payments with actual economic activity. The report found that there is little transparency about the tax affairs of mining companies. The three Australian companies reported on in detail were Perseus Mining, MMG and Iluka Resources.
