Harmful Tax Practices 2018 Progress Report on Preferential Regimes : Inclusive Framework on BEPS: Action 5 BEPS Action 5 is one of the four BEPS minimum standards which all Inclusive Framework members have committed to implement. One part of the Action 5 minimum standard relates to preferential tax regimes where a peer review is undertaken to identify features of such regimes that can facilitate base erosion and profit shifting and therefore have the potential to unfairly impact the tax base of other jurisdictions. This progress report is an update to the 2015 BEPS Action 5 report and the 2017 Progress Report. It contains the results of review of all BEPS Inclusive Framework members’ preferential tax regimes that have been identified since the BEPS Project. The results are reported as at January 2019. In addition the Inclusive Framework agreed on a new standard for substantial activities requirements for no or only nominal tax jurisdictions. This report includes the details of this new standard and the other work on additions to and revisions of the harmful tax practices framework. Finally it contains next steps for the work on harmful tax practices.
