The latest BEPS updates are detailed in EY’s Global Tax Report, with the underlying premise of transparency.
Summary:
OECD: On 5 December 2016, the OECD released an updated version of the Guidance on the Implementation of Country-by-Country Reporting, providing flexibility for notification filing dates for countries not requiring a country-by-country (CbC) report for 2016.
Belgium: New innovation deduction covering patent and other IP rights.
EU: Proposal for hybrid mismatch rules with non-EU countries
Norway: Adoption and regulations for CbC reporting
UK: Interest limitation rules, among other provisions
US: CbC Form 8975 released
From a MNE perspective, it is increasingly apparent that deductions to, and benefits from, tax haven countries are under attack and substance is the key to business and tax decisions.
