IFA Australia contributes to the global IFA scientific research program in various ways. Along with having a member of its Executive Committee, Miranda Stewart, act as Vice Chair of the global organisation’s Permanent Scientific Committee, members of IFA Australia also contribute annually by way of national reporters on two selected topics. These reports are then published in IFA’s annual publication on international tax, the Cahiers de droit fiscal international.

The subjects for the Australian National Reporters for the IFA 2022 Berlin Congress are as follows:
Subject 1
Group approach and separate entity approach in domestic and international tax law
Antony Ting (University of Sydney); Peter Stinson (Ernst & Young)
Subject 2
Big data and tax – domestic and international taxation of data driven business
Tom Ickeringill (Allens)

Subject 1 grapples with how developments in base erosion and profit shifting have affected whether systems of corporate taxation employ the separate entity approach or the group approach in assessing multinational groups, particularly in the context of cross border transactions. Questions that arise include how to approach taxing a transaction involving a larger group: what are the various approaches that can be taken, how do BEPS Pillars 1 and 2 factor into this decision, and how do we overcome the practical challenges that will likely arise?

With the rise of global business models that employ the collection, aggregation, structuring, and analysis of large amounts of data, questions arise as to whether existing measures of tax liability are sufficiently accurate and reliable when it comes to ‘Big Data’. Subject 2 dives into the various features of such businesses, and how they are and should be treated under domestic tax law, international tax systems, and indirect taxation regimes.

The subjects for the Australian National Reporters for the IFA 2023 Cancun Congress are as follows:
Subject 1
Sharing and shifting losses – the “new” profit shifting?
Michael Charles (Pitcher Partners); Leo Gouzenfiter (Pitcher Partners)
Subject 2
Good faith in domestic and international law
Paul McNab (DLA Piper)

While the practice of shifting profits to lower tax liability is becoming better known, a growing worry is that the entitlement to loss compensation for businesses can possibly result in the commoditization of losses. This could occur as companies try to use or trade their losses to receive tax relief which they would not otherwise be entitled to under ordinary principles. Subject 1 considers the extent to which countries currently deny taxpayers the chance to offset losses that actually were incurred in economic terms – what, then, would a just and equitable middle ground look like?

Lawyers and law experts the world over would be familiar with the concept of good faith as a principle that underlies the efficient running of a legal system. Despite its importance, however, ‘good faith’ can be challenging to define – and it often is easier to understand specific concepts under its umbrella such as estoppel or legitimate expectation. But how does good faith factor into systems of domestic and international tax? Understanding this requires a comparison of the role and purpose of good faith in various domestic and international tax systems, as well as the assessment of whether its presence should be reinforced to establish harmony and certainty in legal outcomes across these systems; matters tackled with in Subject 2.

Australia also participates in the IFA scientific and technical program with expert representatives taking part in panels at the annual global Congress. This includes representation at the forthcoming IFA Berlin 2022 Congress:
Australian Speaker(s)
Seminar Panel A
The linking of tax systems: dependence of domestic taxation on foreign tax treatment
Dr. Mark Brabazon (New South Wales Bar Association)
Seminar Panel C
Use of technology in taxation
Mr. Robert Thomson (Australian Taxation Office)
Seminar Panel G
Developing countries and BEPS
Professor Miranda Stewart – Chair (University of Melbourne); Mr. Michael Lennard (United Nations, Chief of International Tax Cooperation)

IFA Cahiers

Since 1939, IFA has published the Cahiers de droit fiscal international every year, a leading annual publication on international tax. The Cahiers address the international tax issues including two main subjects to be discussed at the Congress each year. Each Cahier comprises a general report, often an EU report, and country Branch reports on each of the two selected subjects.  

The Cahiers are distributed for free digitally to all members of IFA every year. Past publications from 1980 are also available to IFA members free of charge and can be accessed through the online membership platform.
