Ahead of India with an average annual outflow of $34.39 billion were China ($107.56 billion), Russia ($88.10 billion), Mexico ($46.19 billion) and Malaysia ($37.04 billion), according to the study published Thursday by Global Financial Integrity (GFI).
In 2011 alone, such outflows drained $946.7 billion from the developing world, up more than 13.7 percent from 2010, when illicit financial outflows totalled $832.4 billion, said the Washington DC-based research and advocacy organisation.
It also marked a dramatic increase from 2002, when illicit outflows totalled just $270.3 billion.
GFI also found that India, with $84.93 billion, was the third top exporter of illegal capital in 2011 behind Russia with $191.14 billion and China with $151.35 billion.
"As the world economy sputters along in the wake of the global financial crisis, the illicit underworld is thriving-siphoning more and more money from developing countries each year," said GFI president Raymond Baker.
"This study should serve as a wake-up call to world leaders: the time to act is now."
The study is authored by GFI Chief Economist Dev Kar and GFI Junior Economist Brian LeBlanc.
"It's extremely troubling to note just how fast illicit flows are growing," stated Kar.
"Over the past decade, illicit outflows from developing countries increased by 10.2 percent each year in real terms-significantly outpacing GDP growth," he said.
"This underscores the urgency with which policymakers should address illicit financial flows."
"Significant progress has been made on automatic exchange of tax information over the past year, with the G20 economies agreeing to exchange tax information between themselves by the end of 2015," said Raymond Baker.
"That said, this study underscores how important it is to quickly extend automatic tax information exchange to non-G20 developing countries," he added.
