US tax reform breaks global rules, EU saysDec. 19, 2017
Last week, the finance ministers of Europe's five biggest economies — Germany, France, the UK, Spain and Italy — wrote an anxious letter to their American colleague, US Treasury Secretary Stephen Mnuchin, and copied it to all senior Republican politicians in the Congress and Senate.
The letter's thrust: The draft US tax bill, if passed as written a week ago, would represent a break with global fair-taxation rules as applied to corporations, and represent a thinly disguised form of trade war.
"The United States is Europe's single most important trade and investment partner," the finance ministers wrote. "It is important that the U.S. government's rights over domestic tax policy be exercised in a way that adheres with international obligations to which it has signed-up. The inclusion of certain less conventional international tax provisions could contravene the US's double taxation treaties and may risk having a major distortive impact on international trade."
A day later, a similar letter was sent to Mnuchin by the European Commission's four most senior economic officials and made many of the same points.
