In total, the OECD (Organisation for Economic Co-operation and Development) estimates that money lost to developing countries through tax havens is three times more than they receive in aid each year.
More foreign investments in developing countries go through tax havens than investments in developed countries, according to ActionAid's report, How Tax Havens Plunder the Poor.
Mike Lewis, ActionAid's tax expert who carried out the research, said: "As we have seen with recent cases like Google and Amazon, tax avoidance is a huge issue here in the UK. But evidence shows that poor countries are losing even more from tax avoidance, and are least equipped to protect fragile public revenues.
"Developing countries are being deprived of billions of dollars of tax revenue by wealthy corporations and investors using secretive tax havens.
"Tax havens are one of the main obstacles in the fight against global poverty. Their secrecy and harmful tax regimes leach money out of developing countries that could be used to end hunger and provide hospitals, schools and clean water."
In another case, a major mining firm is reported to get 84% of its revenue from Africa but has just four of its 81 subsidiaries registered in African countries, and 47 registered in tax havens.
The report comes shortly before the G8 Summit in June when world leaders, including David Cameron, have an historic opportunity to call time on tax havens. The UK is responsible for one-in-five global tax havens, more than any other country. G8 countries are collectively responsible for 40% of tax havens.
Research by ActionAid shows that 98 of the FTSE 100 companies use tax havens, showing the high involvement of British companies.
