The European Commission plans to slam Amazon today with overdue tax bills “worth several hundred mn EUR,” according to the Financial Times (paywall). The move follows a nearly three-year long investigation alleging “that the US online retailer benefited from a sweetheart tax deal that granted it almost a decade of illegal state support from Luxembourg, the hub of its EU operations.” It also comes as part of a wider EU crackdown on multinational corporations for tax evasion, being the Commission’s fourth case in around half a dozen tax probes it has launched since 2013.
