Beginning in 2015, Switzerland has struggled over the adoption of a tax system that is consistent with B.E.P.S. Many different stakeholders are involved, ranging from the Swiss Federal government to the cantons, various political parties, and the E.U. At last, a version of tax reform has been adopted by the Swiss Federal National Assembly. Known as the Federal Act on Tax Reform and A.H.V. Financing ("T.R.A.F."), it contains provisions designed to please all participants while maintaining Switzerland's global reputation as an attractive jurisdiction for multinational enterprises. Danielle Wenger and Manuel Vogler of Prager Dreifuss AG, Zurich, guide the reader through the various iterations of the reform and the provisions of the T.R.A.F.
