The OECD released a public request for input on the base erosion and profit shifting (BEPS) action plan Action 11 on 4th August 2014. Action 11 aims  to establish methodologies to collect and analyse data on BEPS.:

Action 11 aims to develop recommendations regarding indicators of the scale and economic impact of BEPS and ensure that tools are available to monitor and evaluate the effectiveness and economic impact of the actions taken to address BEPS on an ongoing basis. This will involve developing an economic analysis of the scale and impact of BEPS and actions to address it. The work will also involve assessing a range of existing data sources, identifying new types of data that should be collected, and developing methodologies based on both aggregate (e.g. FDI and balance of payments data) and micro-level data (e.g. from financial statements and tax returns), taking into consideration the need to respect taxpayer confidentiality and the administrative costs for tax administrations and businesses.

The OECD wants to identify relevant data which are currently collected and available for analysis in a specific country for a larger group of countries and other relevant data that could be utilized to analyze and monitor BEPS, e.g. economically available datasets.

Comments are also invited on:

  • issues to be excluded in a quantitative measure of BEPS;
  • potential methodologies for estimating the scale and impact of particular BEPS behavior;
  • suggestions on  which effective tax rates (ETRs) should be used for monitoring BEPS;
  • data and methodologies to assess BEPS-related spillover effects;
  • data and methodologies to develop an economic analysis of the effects of BEPS counter-measures; and
  • data collection tools to monitor the effectiveness of the actions taken to address BEPS on an ongoing basis.
