Following an in-depth investigation launched in October 2014, the Commission has concluded that a tax ruling issued by Luxembourg in 2003, and prolonged in 2011, lowered the tax paid by Amazon in Luxembourg without any valid justification. The tax ruling enabled Amazon to shift the vast majority of its profits from an Amazon group company that is subject to tax in Luxembourg (Amazon EU) to a company which is not subject to tax (Amazon Europe Holding Technologies). In particular, the tax ruling endorsed the payment of a royalty from Amazon EU to Amazon Europe Holding Technologies, which significantly reduced Amazon EU's taxable profits.
