Presto Vivace writes in with this story of a European Commission investigation into a secret tax agreement between Amazon and Luxembourg. "Leaked tax documents from accounting firm PwC in Luxembourg show how Amazon sidesteps the 30 per cent tax rates local [Australian] players face. The Luxembourg documents, obtained in a review led by the International Consortium of Investigative Journalists, contain some of the first hard numbers and details on how Amazon pays virtually no tax for its non-US earnings, including in Australia. Last month, the European Commission announced an investigation into the secret 2003 advance tax agreement Amazon struck with Luxembourg that is the key to its global tax strategy. The Luxembourg documents show not only the extent of the related-party transactions in Amazon's Luxembourg companies but how Amazon has changed its tax strategy after investigation by French tax authorities and the US Internal Revenue Service. The change is so dramatic it raises questions whether the European Commission is targeting the right transactions."
