The finance ministers of Britain, France and Germany have launched a drive to force big business to pay its fair share of tax and halt the schemes of top firms to keep payments to a minimum.
Britain's George Osborne, France's Pierre Moscovici and Germany's Wolfgang Schaeuble said it was time for internationally co-ordinated action to clamp down on the practice of shifting profits from the company's home country to pay less tax under another jurisdiction.
The drive - which is backed by a study by the Organisation for Co-operation and Economic Development (OECD) on the consequences of the so-called profit shifting - comes as cash-strapped governments try to use every means to inject new funds into their budgets.
"We are talking about something that is fundamentally legal. We need to modify the law," said OECD secretary general Angel Gurria. "Avoiding double taxation has become a way of having double non-taxation.
"No single country can go by itself," he said at a news conference on the sidelines of the G20 finance ministers' meeting in Moscow, insisting that the drive was not aimed at "bashing" individual corporate giants.
Schaeuble said it was "unfair that multinational companies should be able to use globalisation as a tool" not to pay their fair share of taxes while Moscovici described the issue as a "matter of fairness for our citizens".
Osborne said current global tax rules had been developed almost 100 years ago - along principles set out by the League of Nations in the 1920s - and few changes had been made since.
"This means that the tax system does not reflect how international companies do business.
"We want businesses to pay the taxes that we set in our countries. And this cannot be achieved by one country alone. No one country can create an international tax system by itself."
The ministers emphasised that their proposal was supported by the Russian presidency of the G20.
Online retailer Amazon, internet giant Google as well as coffee shop chain Starbucks have been under the spotlight for their tax strategies in Britain and other EU countries in recent months.
