On June 5, 2021, the Finance Ministers and Central Bank Governors of the G7 countries issued a Communiqué announcing their agreement on the conceptual framework for a substantial revision to global tax policy (the “Communiqué”). The Communiqué puts the G7’s stamp of approval on recent efforts by the OECD (supported by a big push by

In a decision dated December 11, 2020 (Value Click Case), the French Administrative Supreme Court overturned a Paris Court of Appeal decision dated March 1, 2018, and concluded that the French affiliate of the group (“French Co”) should be considered as the dependent agent of the Irish affiliate company (“Irish Co”) in France for permanent establishment (“PE”) purposes. The decision is a significant reversal of prior court cases, such as the Google decision dated April 25, 2019, and it may lead to the unilateral application by France of an expansive interpretation of the definition of PEs under Article 12 of the MLI adopted with no reservation by France.

Just in time for the holidays, the OECD has published detailed guidance about the impact of the COVID-19 pandemic on transfer pricing. The guidance has useful information for taxpayers and tax administrations alike. It contains general advice on the application of basic transfer pricing principles during the pandemic, as well as specific advice on four issues: (i) comparability analyses, (ii) allocating losses, (iii) government-assistance programs, and (iv) advance pricing arrangements (“APAs”). The OECD guidance is broadly consistent with comments we made in a prior post about the impact of the pandemic on transfer pricing.

As indicated in an earlier post, the EU Commission had proposed in July to amend the Directive on Administrative Cooperation, to extend the EU tax transparency rules to digital platforms. The Member States have now agreed on the proposal. The agreed proposal on administrative cooperation (DAC 7) will ensure that Member States automatically exchange information on the revenues generated by sellers on digital platforms, whether the platform is located in the EU or not.

The European Union passed a sixth version of its Directive on Administrative Cooperation in the Field of Taxation, known as “DAC 6” (Directive (EU) 2018/82 2), on 25 May 2018. DAC 6 introduces reporting requirements for professional intermediaries (and under certain circumstances tax payers) relating to their involvement in a wide range of cross-border arrangements and transactions featuring “hallmarks” of tax planning concerning one or more EU Member States or the UK. These are referred to in DAC 6 as “reportable cross-border arrangements“. Specific hallmarks relate to transfer pricing (category E) and they do apply without main benefit test.

Failure to comply with DAC 6 could imply significant penalties under domestic legislations of the EU member states (and the UK) as well as reputational risks for not only intermediaries ( law firms, accounting firms , banks …) but also for businesses and individuals.

Multinational Enterprises (“MNE”) that are looking to mitigate their exposure to market changes provoked by crisis may find themselves considering the termination or suspension of intercompany agreements with non-performing parties. Terminating an existing intercompany agreement can very well be a key step that an MNE undertakes to protect its business; however, MNEs should also be aware that terminating arrangements could lead to unintended transfer pricing and tax consequences and may ultimately impact the structure of the group.

COVID-19 has placed unforeseen stress on the distribution structures of Multinational Enterprises (“MNE”) due to catastrophic losses and costs from supply chain interruptions and plummeting demand. Existing intercompany agreements most likely do not cover the allocation of catastrophic costs or losses and several questions may need to be addressed. For example, should catastrophic costs be shared among group members, and if the answer is yes, then how?

This week is a busy week for the digital industry. The EU Court of Justice is closing two cases involving digital-economy giants. At the same time, the EU Commission released its new Tax Package covering three separate but related initiatives: a Tax Action Plan (25 distinct actions) to make taxation “simpler, fairer and better attuned to the modern economy over the coming years,” a proposal on administrative cooperation (“DAC 7”) extending EU tax transparency rules to digital platforms, and a Communication on tax good governance proposing a reform of the Code of Conduct, which addresses tax competition and tackles harmful tax practices within the EU. DAC 7 and the new transparency rules will directly impact the digital industry.

Many multinational enterprises (“MNEs”) are providing new forms of financial, technical, or other support to group members facing COVID-19-related business issues such as plant (temporary) closures or supply chain disruptions. This support may in some cases give rise to a transfer of value, such as the knowhow of a seconded employee. It may also involve a transfer of assets coupled with the ability to perform certain functions and assume certain risks. Such transfers could be viewed as a “business restructuring” as defined by the Chapter IX of the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (2017) (the “OECD Guidelines”) and may trigger transfer pricing and tax consequences.
