The LuxLeaks (or Luxembourg Leaks) scandal surfaced in November 2014 when the International Consortium of Investigative Journalists (ICIJ) exposed several hundred secret tax rulings from Luxembourg, which had been leaked
by former employees of PricewaterhouseCoopers (PwC). The LuxLeaks dossier allegedly documented how hundreds of multinational corporations were using the system in Luxembourg to lower their tax rates, in some cases to less than one per cent (source).
