The challenges and opportunities of new technologies in the tax field Technological developments induced major reforms in the regulatory international and domestic tax landscapes as well as in the developments in the use of technology by tax administrations and taxpayers. New technology, especially the innovations in virtual asset-light cross-border business organizations, data analytics, service and process automation, on one hand, disrupted the well-established legal tax principles and rules and, on the other, stimulated informed data-driven and structured solutions in tax compliance. Technological advances affected nearly every area and each aspect of taxation: Direct tax regulations, indirect tax law, and tax procedures including tax compliance, and tax control functions. International organizations such as the Organization for Economic Co-operation and Development (OECD), the United Nations (UN), and the European Commission as a supranational organization fostered critical legislative reforms and proposals among which are the OECD Two-Pillar Solution to Address the Tax Challenges Arising from Digitalisation of the Economy, Article 12B of the UN Model Tax Convention to tax automated digital services, new rules for tracing transfers of crypto-assets in the EU, as well as the EU ́s VAT e-commerce package and "VAT in the Digital Age" package. While these proposals aim to address a wide range of the benefits and challenges of Economy 4.0, certain questions arise concerning the consistency of the legislative developments with their initial objectives, the appropriateness of the legal form for the economic substance of the regulated relations for the effectiveness of the regulations as well as their coherence. This volume contains a collection of scientific chapters on the general topic "Tax and Technology" that were successfully completed by the 2022/2023 LL.M. graduates of the Institute for Austrian and International Tax Law, WU. The volume is divided into three parts that contain the contributions dealing with the impact of the technology on international tax law, indirect tax law, and procedural law. Each chapter provides an in-depth analysis of a unique research question aiming to innovatively contribute to the current debate and develop a practical approach for implementing the findings.

Dependent Agents as Permanent Establishments The article on business profits may be the most relevant one in tax treaties. If patterned after the OECD Model Tax Convention, this article allocates the exclusive taxing right over the profits of an enterprise to the residence country, unless the enterprise carries on business in the source country through a permanent establishment. Considering the importance of allocating taxation rights, tax authorities and courts of many countries have increasingly focused on the concept of agency permanent establishment. This book includes 12 chapters which provide an in-depth analysis of the key aspects that need to be taken into account for interpreting the concept of agency permanent establishment. It incorporates the perspectives of leading scholars and practitioners dealing with international tax cases. This book is designed to provide essential insights to academics, practitioners, tax officials and judges who deal or are interested in the field of international taxation.

An in-depth analysis of the specific aspects of justice, equality and tax law "Justice, Equality and Tax Law" is a topic that is both old and new at the same time. Even if the society changes, the demands that tax needs to be just and equal seem to be immutable. What changes, of course, is the perception of the content of those demands. International taxation post-BEPS has been fraught with new challenges that warranted urgent responses. These challenges were mainly provoked by the unprecedented rise of the digital economy which truly marked a change in the way business is conducted, how value is created, and how goods and services are produced and consumed. Digitalization, in turn, had repercussions on all aspects of taxation - direct taxation, indirect taxation, and even tax procedures. For instance, the quest for more justice and equality in profit taxes was the reason why, in October 2021, a historical deal based on a two-pillar solution to address the tax challenges arising from the digitalization of the economy was negotiated within the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting and agreed upon by 137 member countries. It was also the motive behind the shift from a typical vendor collection model to an intermediary collection model supported by centralized registration points in indirect taxes, notably the VAT/GST. Abundant data from the European Union or the OECD signalized an ever-increasing gap between expected VAT revenues and VAT actually collected, making it obvious that the classical system of VAT/GST collection was unable to respond to challenges posed by the digital economy. Therefore, new solutions based on the participation of digital platforms as intermediaries had been introduced. Finally, new technologies, such as blockchain, paved new avenues in enhancing tax compliance. In this context, this volume entitled "Justice, Equality, and Tax Law" contains not only a selection of the best master ́s theses of the full-time LL.M. programme in 2021/2022 but also represents an in-depth analysis of various aspects of this evergreen topic.

The Multilateral Instrument (MLI) proposed in OECD BEPS Action 15 will lead to the modification of numerous tax treaties. As tax treaties can have different wording, terminology and structure, a great challenge is to find a proper way to accomplish their modification without distorting the underlying framework or triggering undesirable effects. This book analyses the MLI, which was signed by over seventy jurisdictions on 7 June 2017. The topics covered include: • the procedural mechanisms on how the new measures to prevent base erosion and profit shifting (BEPS) will interact with and complement existing tax treaties; • the scope of the MLI in order to ascertain which tax treaties and taxes are covered; • the interpretation of terms used in the MLI and the relationship between the languages used in the MLI and in the particular tax treaties; • the implementation of the minimum standard through the MLI, as well as how states can exercise various options offered by the MLI and reserve the right not to apply certain provisions of the MLI; • the legal consequences of the exercise of options and reservations for the other states; • the notification procedure through which states declare their choices; and • the possibilities and procedure for withdrawal from the obligations entered into upon signing the MLI. Finally, the book discusses whether the mechanism of the MLI can serve as a role model for future changes to the OECD Model Convention. The book incorporates the analyses of leading scholars and practitioners dealing with international tax matters. Critical insights are offered for academics, practitioners, tax officials and judges who deal with or are interested in the field of international taxation.

Time to discuss anti-BEPS measures around digitalization In the course of the BEPS Report on Action 1, it was concluded that there was no instantaneous need for specific rules to address base erosion and profit shifting (BEPS) made possible by the digitalization of enterprises and new digital businesses. At the same time, it was acknowledged that general measures may not suffice with the assessment of results to begin in 2020. While awaiting possible fundamental reforms of the tax framework, it is time to discuss anti-BEPS measures bearing in mind the peculiar features of the digital economy such as increased mobility, no need for physical presence, and dematerialization.
