Global Tax Treaty Commentaries (GTTC)

Global Tax Treaty Commentaries (GTTC) 

The IBFD Global Tax Treaty Commentaries (GTTC) is the authoritative source for analysis and interpretation of tax treaty practices across the globe. This peer-reviewed, cutting-edge publication is authored by world-class academics and tax practitioners.

The GTTC Model articles and Issues collection provides high-level analysis of and commentaries with respect to each article in the OECD Model and the UN Model, along with a series of chapters on meta-topics. The GTTC Country Policy and Practice guides offer a comprehensive analysis of the treaty practice of many countries worldwide.

GTTC Country Policy and Practice identifies patterns in the tax treaties of a country and the main deviations from the OECD Model, UN Model and/or national tax treaty model in its policy and practice. The possible existence of a standard country treaty model and the presence of and reasons for any tax treaty deviations from the OECD and UN Models are assessed. This could include revealing different policies for treaties entered into with developing and developed countries. Furthermore, the publication reflects practical issues regarding the interpretation of treaty provisions by courts and tax administrations. GTTC Country Policy and Practice also indicates whether case law or tax rulings on the interpretation of treaties of a jurisdiction refer to recommendations from international organizations such as the OECD and UN or the Vienna Convention on the Law of Treaties.

The GTTC collection set incorporates the alternative treaty instruments developed in recent years in relation to tax administrative cooperation. These include tax information exchange agreements (TIEAs), the multilateral mutual administrative assistance (MMAA) treaty and ,of course, the Multilateral Instrument and how it has affected domestic treaty policy and tax treaties already in force.

The two collections, focusing on model analysis and country practice respectively, are intertwined. They follow an organic structure that will do justice to the interaction of the articles of the OECD Model and the UN Model in theory and practice in various countries. The publications are regularly updated, with all revisions remaining connected with each other. An abundance of material on the interpretation and application of treaty variations found in many countries but not reflected in the models is systematically analysed. Authors substantiate their statements by reference to the OECD Model and the UN Model, official commentaries, treaties, case law, journal articles and other sources, all accessible via hyperlinks.

GTTC Model Articles and Issues:

As theory and practice do not always coincide, this publication covers commentary not only on the model conventions but also on the most important variations, as well as diverging national tax treaty policies. The commentaries are based on the perspectives of internationally renowned experts on each article. The collection gives a complete picture of the realities of everyday international tax treaty practice and reflects the impact of recent instruments such as the MLI, tax information exchange agreements (TIEAs) and the MMAA treaty.

GTTC Model Articles and Issues has been completed and consists of 30 chapters, each dedicated to one of the articles of the OECD and UN Model provisions, along with six chapters on important meta-topics relating to specific issues: “Treaty Interpretation”, “Interaction of Tax Treaties with International Economic Laws”, “Time in Tax Treaties”, “Application of Tax Treaties to Fiscally Transparent Entities”, “Qualification Conflicts”, “Beneficial Ownership” and “Triangular Cases”. By weaving all these aspects together, in combination with seamless links to other content on the IBFD Tax Research Platform, IBFD offers tax professionals – from the advisory and corporate sectors to government and the judiciary, along with the academic arena – a rich tapestry of information unmatched by any existing product.

GTTC Country Policy and Practice:

GTTC Country Policy and Practice reveals the hidden pattern in the tax treaty policy of a country and the main deviations from the OECD Model, UN Model and/or national tax treaty model in its policy and practice. It now covers 20 countries, and more are to follow from all continents. GTTC Country Policy and Practice is deeply linked to GTTC Model Articles and Issues, matching an analysis of each model article in general with the country perspective. The chapters will be highly standardized, enabling search and comparison per article per country. The publication is suitable for tax professionals from the corporate and advisory sectors, as well as for governments, universities, and the judiciary.

The scholars, practitioners and tax officials authoring the publication establish whether a jurisdiction uses its own (official or non-official) tax treaty model or follows a documented tax treaty policy. These top-notch experts determine the possible existence of a standard country treaty approach per country. They assess the presence of and the reasons for any tax treaty deviations from the OECD and UN Models and determine whether there are different policies for treaties entered into with developing and developed countries. The collection allows the user to get a comprehensive view per treaty article per country. It helps to elucidate not only the different articles of the model conventions and the diverging national treaty policies but also how each rule has been incorporated in a country’s treaty network and policy. It thereby takes the same approach as used in the GTTC Model Articles and Issues publication.

The collection also addresses whether case law or tax rulings on the interpretation of treaties of a jurisdiction refer to recommendations from international organizations such as the OECD and UN or the Vienna Convention on the Law of Treaties. GTTC Country Policy and Practice will be regularly updated to track developments and assess the effect of new instruments like the MLI on domestic treaty policy and the tax treaties already in force.
