The thesis deals with issue of international double taxation with respect to taxes on income and capital. The aim of the thesis is to provide a comprehensive overview of the issue of concluding international double tax treaties and to verify, whether the differences in their provisions can be significant enough to affect activities of internationally active entities. The body of the thesis is divided into three chapters. The first chapter explains what double taxation is, how it occurs and the possible ways of its elimination. It also deals with related tax evasion. The second chapter is devoted to bilateral and multilateral tax treates. The emphasis is on OECD and UN model conventions and related issues of exchange of information, non-discrimination and dispute resolution. The third chapter focuses on the approach of the Czech republic to enter into tax treaties. Its main part is devoted to a comparison of tax treaties which the Czech republic has concluded with the United States of America, Slovakia and Germany.

Double taxation could arise in a situation where resident- resident conflicts occur. Resident–resident conflicts occur in the situation where both countries regard such a person as a “resident” for tax purposes under their domestic legislation. For that reason, all income that is earned by that person, irrespective of the jurisdiction it is earned in, will be subject to tax in both countries. In order to resolve these conflicts, the Organisation for Economic Cooperation and Development’s (“OECD’s”) Model Tax Convention contains a tie breaker clause which states that a non-individual shall be deemed to be a resident only of the State in which the ‘place of effective management’ is situated. It was found that although there were conflicting views, the expression ‘place of effective management’ was mainly determined with reference to the place where real management actually makes decisions on key business affairs of the company. Based on the following reasons it was concluded that using ‘place of effective management’ as a tie breaker rule was ineffective. • With improved communication technology and increased mobility of top level management, it makes it very difficult to pinpoint a single location where the ‘place of effective management’ is positioned; • Changes to the generic managerial structures seen in the past, makes it increasingly complex to determine where the ‘place of effective management’ is situated; and • There is no universal interpretation of the term ‘place of effective management’ within the international arena. Against the backdrop that each option for determining the ‘place of effective management, analysed in Chapter 4 had its own flaws, it is almost impossible to determine a company’s residency based on a single test. It was therefore, recommended that the tie breaker rule consist of a hierarchy of the following tests. 1. Deemed to be resident of the country in which place of effective management is situated, as defined by SARS’ interpretation. 2. Deemed to be a resident of the country in which its economic nexus is the strongest. 3. Conflict to be resolved by mutual agreement between the two Contracting States. / Thesis (M.Com.

L’objet de cette thèse est de proposer un régime fiscal applicable à l’imposition des revenus passifs dans les situations triangulaires internationales. La première partie est consacrée à analyser la nature objective du risque de double imposition. Ce sont les situations triangulaires « passives » ou « subies ». La seconde partie est consacrée à analyser des situations triangulaires « actives » ou « choisies » qui peuvent être propices à la mise en place de structures fiscalement « avantageuses ». L’étude est complétée par des propositions de modification du Modèle de convention fiscale. / The purpose of this work is to propose a tax treatment applicable to passive income in international triangular tax cases. The first part of the study is dedicated to the analyses of the double tax exposure. These are “passive” triangular cases or “incurred”, where potential double tax and uncertainty creates an issue for economic growth. The second part of the study is dealing with “active” triangular situations that may be motivated by the tax benefit resulting from these structures. The conclusion of our study will include proposals to amend the OECD treaty Model.

The present diploma thesis is focused on the definition of differences resulting from the comparison of two chosen forms of doing business of a foreign person in the Czech Republic. It specifies differences from the viewpoint of the commercial law and the obligations as an accounting unit. Foremost, the thesis includes a detailed analysis from a tax point of view. The thesis involves a model example to define the precise amount of tax obligation incumbent on the both forms of business of a foreign person in the Czech Republic. This model example constitutes a basis for the final evaluation and to draw relevant conclusions. Suggestions and recommendations mentioned in this work can serve as an overview of the approach to the taxation of cross-border income and at the same time as a tool for the elimination of errors and discrepancies in connection with the chosen form of business of a foreign person in the Czech Republic.
