The OECD BEPS project continues to dominate the international tax world with the UK government’s view published alongside the Budget and further significant discussion drafts published by the OECD itself. Draft legislation has been published to remove the extended time limit restriction introduced in FA 2007 that impacted certain EU claims and, staying with EU law, the AG has issued an opinion on the Dutch fiscal unity rules. In Switzerland, guidelines on the taxation of principal companies have been published which could impact groups which already have or are planning to establish principal company structures there.
