We will analyze the leaks on the web tax documents from Luxembourg, and then we will decide whether to launch new investigations, said Commissioner Magrete Vestager.
"If it is confirmed that the documents are legitimate and contain classified information about the European market, it means that the EC will order a full investigation," Vestager added.
The statement came after Luxembourg said the documents were "stolen" and the government was not responsible for the leaked information. However, the Commission rejected this argument and confirmed that it would seek legal liability.
The EC also stated that this investigation will lead to a new wave of tax investigations, and all previous reports will be subjected to a new, more comprehensive and in-depth analysis.
Leaked classified information relating to Luxembourg tax administration (known as "Lyuksliyks"), sparked a debate about the liberal tax system and provoked many to think that the EC had been "turning a blind eye" until this point. According to the documents, over 240 international companies are based in the duchy, paying just 0.25% on their profits.
