Sharing and shifting of corporate losses – The new profit shifting?
René Matteotti (Switzerland)
Chair: Sam Kaywood (USA)
The panel will review arrangements to shift of losses among entities in a multinational group to optimize tax planning as well as tools deployed by tax authorities to combat them. In particular, the panel will cover the migration of assets or companies with built-in losses to other jurisdictions, the duplication of losses in different countries, the use of transfer pricing arrangements to transport profits or losses (through the migration of intangibles or otherwise), techniques to refresh expiring tax attributes and the use of financial arrangements to base erode a high-tax jurisdiction while creating stateless income. The panel will explore specific tools to implement these arrangements, including the use of dual resident companies, cross-border reorganizations, hybrid instruments and hybrid entities. The panel will also consider the use of “soft doctrines” to attack these arrangements as well as the impact of Pillar 2.

Good faith in domestic and international tax law
Craig Elliffe (New Zealand) and Sjoerd Douma (Netherlands)
Chair: Hon. Marshall Rothstein, CC, KC (Canada)
Good faith is a fundamental legal principle in international law and most domestic legal systems worldwide, both civil and common law. The meaning of good faith varies across different contexts and jurisdictions, which can be a challenge in the international context where consistency is desirable. In the domestic tax context, good faith can be relevant to the relationship between taxpayers and tax authorities. In the international tax context, the good faith principle applies to dealings between contracting States, in particular to tax treaties and their interpretation. It is similarly relevant to dealings between taxpayers and the tax authority of a contracting State. This panel will explore various issues, focusing on the history and foundation of the principle of good faith in the international context; the application of this principle in the tax treaty context, including potential remedies for breaches; and the application of this principle against the background of selected current issues in international tax practice and illustrated by specific case studies.

Attribution of profits to PE’s: AOA vs. UN Model
Chair: Richard Vann (Australia)

Who is winning the race?
Chair: Natalia Quiñones Cruz (Colombia)
This seminar will discuss whether base erosion and profit shifting (BEPS) has been fully addressed by the current rules or if mobility, new technologies, and new business strategies make BEPS a persistent challenge for the international tax system. The seminar will additionally address the issue of whether BEPS is the same across the globe or if it has a particular detrimental effect for the developing world. Finally, the seminar explores some options to address the issue of persistent BEPS, which range from continuing with the implementation of current rules to unitary taxation and formulary apportionment.

International mobility and remote work: Corporate tax implications
Chair: Ana Claudia Utumi (Brazil)
The purpose of this panel is to examine the international tax implications, especially for multinational enterprises (MNE), to have personnel working at distance, having them relocated to other countries, or even directly hiring people that live in other countries as employees. Many of the MNEs reduced the sizes of their physical offices, showing that remote work came to stay, and not as a temporary measure.
The number of issues related to international relocations/international employees is significant. Characterisation of permanent establishment, interaction with other companies of the group to share costs/functions exercised by certain employees, taxation of cross-border services, impact of tax treaties on remuneration for the services provided by those employees, taxation on the use of digital means to allow the remote work, determination of tax residency etc.

Transfer pricing controversial topics - problems and solutions
Chair: Monique van Herksen (Netherlands)
The panel will look at transfer pricing controversy and resolution trends, and consider the impact of new developments, such as a Global Minimum Tax. The following questions will be raised: Is it time to conclude that Profit Split and TNMM are the de facto methods of choice (witness recent tax litigation) or is their application merely opportunistic depending on whose side you are on and what outcome you support? Considering this, do APAs and MAP provide adequate dispute resolution or should other (international) instruments be used? Will the Global Minimum Tax reduce transfer pricing controversy?
