Europe is targeting Big Tech with new taxes. It’s straining the transatlantic alliance.

Last week, President Trump ordered an investigation into France’s new tax on Apple, Facebook, Google and other large digital companies. The administration is considering strong retaliatory measures, on the grounds that it unfairly targets U.S. companies.

This is the latest stage in a long-running battle. France introduced its “digital services tax” because it felt that the Group of 20 nations weren’t making progress toward a new global agreement on taxing technology companies. Britain, Spain, Italy and others are pursuing similar taxes.
