All OECD and G20 countries have committed to implementing country by country (CbC) reporting, as set out in the Action 13 Report “Transfer Pricing Documentation and Country-by-Country Reporting”. Recognising the significant benefits that CbC reporting can offer a tax administration in undertaking high level risk assessment of transfer pricing and other BEPS related tax risks, a number of other jurisdictions have also committed to implementing CbC reporting (which with OECD members form the “Inclusive Framework”), including developing countries. Jurisdictions have agreed that implementing CbC reporting is a key priority in addressing BEPS risks, and the Action 13 Report recommended that reporting take place with respect to fiscal periods commencing from 1 January 2016. Swift progress is being made in order to meet this timeline, including the introduction of domestic legal frameworks and the entry into competent authority agreements for the international exchange of CbC reports. MNE Groups are likewise making preparations for CbC reporting, and dialogue between governments and business is a critical aspect of ensuring that CbC reporting is implemented consistently across the globe. Consistent implementation will not only ensure a level playing field, but also provide certainty for taxpayers and improve the ability of tax administrations to use CbC reports in their risk assessment work. The OECD will continue to support the consistent and swift implementation of CbC reporting. Where questions of interpretation have arisen and would be best addressed through common public guidance, the OECD will endeavour to make this available. The guidance in this document is intended to assist in this regard. Some questions and answers refer to articles of the Model Legislation related to Countryby-Country Reporting contained in the Action 13 Report (“Model Legislation”). Such references do not mean that countries’ domestic legislation should follow word-for-word the provisions in the Model Legislation. As indicated in paragraph 61 of the Action 13 Report “jurisdictions will be able to adapt this model legislation to their own legal systems, where changes to current legislation are required”. Countries’ domestic legal framework should however, be substantively consistent with the Model Legislation. Updated November 2017.
