The news brought immediate condemnation from politicians across Europe and led to two tax investigations by the European Parliament, which promised to stamp out the so-called "sweetheart deals" and bring transparency to the EU's tax regime.
The scandal brought further investigations into tax arrangement run by Apple, Starbucks and other major companies, as well as calls for companies to be forced to pay taxes on the sale of products and services in the country in which each transaction was actually made.
However, new research from the European Network on Debt and Development (Eurodad) shows that, since the LuxLeaks scandal, the amount of secret 'sweetheart deals' between multinational corporations and European governments has increased by almost 50 percent.
"It's very surprising and deeply worrying to see that the amount of secret sweetheart deals is skyrocketing in Europe — as if the LuxLeaks scandal never happened," said Tove Maria Ryding, Tax Justice Coordinator of Eurodad.
"We know from examples like the Apple case and LuxLeaks that these secret deals can be used for large scale tax avoidance by multinational corporations. And as we can see with the LuxLeaks trial, anyone who tells the public what's in these deals can get threatened with lawsuits and jail time."
"The fact that multinational corporations now have more than one thousand sweetheart deals in Europe is deeply concerning, to say the least," Ryding said.
Developing Countries Losing Fortunes
According to the report, following LuxLeaks, the amount of deals kept increasing dramatically, from 547 in 2013 to 972 in 2014, finally reaching 1444 by the end of 2015. According to the report's analysis of new European Commission data, an increase of 160 percent in just two years.
"European countries also keep signing deeply problematic tax treaties with developing countries. The 18 European countries we've analyzed have no less than 752 treaties with developing countries. On average, these treaties lower developing country tax rates with 3.8 percent, and some of them are much more extreme than that. Developing countries are losing fortunes due to these treaties," Ryding said.
