The European Commission published its ambitious anti-tax avoidance package on 28 January 2016. It is a follow-up to its June 2015 Action Plan. The aim of the package is to ensure that member states take a coordinated stance both in the implementation of the BEPS project and against tax avoidance. The four main elements are an Anti-Tax Avoidance Directive, a recommendation on tax treaties, a revision of the CbCR directive and a communication on third country tax governance. Some member states are likely to be concerned about these proposals, which will require changes to national laws.
