Technological advances have had a major impact on traditional retail shopping changing it from a physical undertaking to a completely digitised experience where consumers buy digital media online. VAT systems that do not specifically provide for, or which have not been adapted to cope with, technology-driven advances, generally do not provide for the adequate levying and collection of VAT on cross-border digital trade. The South African VAT system is no different. The taxation of e-commerce should not artificially advantage or disadvantage e-commerce over comparable traditional commerce, or unnecessarily hinder the development of e-commerce. This thesis determines whether the South African VAT Act 89 of 1991 in its current form, can be applied adequately to raise and collect VAT on cross-border digital transactions. Where shortcomings in the VAT Act are identified, the harmonised VAT rules of the European Union (EU), together with the Organisation for Economic Cooperation and Development (OECD) proposals on consumption taxes, are analysed and discussed to seek possible solutions and make recommendations. / Mercantile Law / LL.D.

Prior to 1994, South African taxpayers had little protection from fiscal legislation or the decisions, actions or conduct of the South African Revenue Service (“SARS”) that violated their common law rights. Parliament reigned supreme and in tax matters, the strict and literal approach to the interpretation of statutes was employed, with the judiciary often quoting the mantra that there is “no equity about tax”. The Income Tax Act (Act No 58 of 1962) was littered with discriminatory and unfair provisions based on age, religion, sex and marital status. Even unreasonable decisions taken by SARS could not be reviewed by the judiciary as “unreasonableness” was not a ground for review of the exercise of a discretion by SARS. On 27 April 1994, the constitutional order changed. Parliamentary supremacy was replaced with constitutional supremacy and the rights to privacy, equality, human dignity, property and just administrative action were codified in a Bill of Rights. The codification of these fundamental rights has materially changed the nature and extent of the rights of South African taxpayers. The objective of this thesis, therefore, is to identify, analyse and discuss South African taxpayers’ rights from a constitutional perspective. The following major conclusions can be drawn from the research done: - the judiciary have been forced to reappraise their approach to the interpretation of statutes from a “strict and literal” to a “purposive” approach that is in accordance with the values underpinning the new constitutional order; - new legislation has amended some of the so-called “reverse” onus of proof provisions that were constitutionally unsound – this should result in greater fairness and consistency for affected taxpayers especially in the area of when penalties may be imposed; - the concept of clean hands and good facts can influence the judiciary when arguing that a taxpayer’s right to just administrative action has been violated; and - discriminatory and unfair legislation and conduct on the part of SARS may and should be attacked on a substantive law basis, especially where human dignity is at stake. The overall conclusion is that taxpayers’ rights are more far-reaching than prior to 1994 but still have some way to go before they are fully interpreted and developed. / Accounting Science / D.Compt.

Trusts are subject to multiple fOl1lls of legislative regulation dealing with taxation and governance. Trusts were widely used by planners as taxavoidance shelters. Tax legislation was amended to subject trusts, other than special trusts as defined, to the highest income tax rate of forty percent, in tel1llS of section 5(2) of the Income Tax Act, 58 of 1962. The inter vivos trust is also subject to a wide range of anti-avoidance measures, including those contained in sub-sections (3) to (8) of section 7 of the Income Tax Act and Part X of the Eighth Schedule to the Act, as well as the general anti -avoidance measures in section 103. These measures impact negatively on the use of trusts for estate-planning purposes. The research objective was to evaluate the use of testamentary and inter vivos trusts for estate-planning purposes and to develop a holistic estate-planniD.g model incorporating these planning instruments. Both the testamentary trust and the inter vivos trust were evaluated against broad principles of effective estate planning and the taxes and duties applicable to them. The research also reviewed the writings of financial planners on various techniques and models used for estate planning, as wells as case studies documented in the literature. The research developed and evaluated holistic estate-planning models incorporating testamentary trusts and inter vivos trusts, respectively. By neutralizing the effects of various taxes and duties, it was demonstrated that it is possible to develop an estate plan that satisfies most of the requirements of effective estate planning.

La thèse est une collection de cinq articles académiques, chacun apportant une contribution originale à la connaissance et à la recherche scientifique dans le domaine de l’économie de l’imposition du capital et des sociétés. Les travaux empiriques de Gaëtan Nicodème se situent dans le contexte de la concurrence fiscale en Europe.<p><p>Le premier chapitre ‘Corporate Tax Competition and Coordination in the European Union: What do we know? Where do we stand? (Publié dans International Taxation Handbook) revisite la problématique de la concurrence fiscale dans l’Union Européenne, discute la littérature économique théorique et empirique sur la question et analyse les réponses politiques qui y sont apportées. Après avoir remis la problématique dans son contexte institutionnel, l’auteur compare les résultats provenant de la littérature avec les caractéristiques propres à l’Union Européenne, notamment en termes de l’étendue et des conséquences de la concurrence fiscale. Il passe ensuite en revue les questions théoriques et de mise en œuvre pratique que soulèvent une possible harmonisation et consolidation des bases fiscales de l’impôt des sociétés en Europe. Tout en gardant à l’esprit la diversité des solutions qui existent dans la mise en œuvre, il montre que l’harmonisation des bases fiscales est à même de générer des gains économiques. Le deuxième chapitre ‘Comparing Effective Corporate Tax Rates’ (à paraître dans Frontiers in Finance and Economics) passe en revue les méthodes de calcul de taux effectifs de l’impôt des sociétés. Le mérite de la contribution est non seulement d’offrir une typologie des ces taux mais également de montrer que leurs résultats sont très différents selon la méthode utilisée, que ce soit en niveau ou en classement des pays. L’auteur calcule également ces taux pour un échantillon de pays Européens avec une désagrégation sectorielle. Le troisième chapitre ‘Do Large Companies have Lower Effective Corporate Tax rates ?A European Survey’ utilise ces méthodes pour étudier s’il existe un lien entre les taux effectifs et la taille des entreprises. Utilisant de multiples méthodes d’estimation, l’auteur trouve un lien robuste et négatif entre le nombre d’employés et le taux effectif d’imposition des entreprises. Le quatrième chapitre ‘Foreign Ownership and Corporate Income Taxation :an Empirical Evaluation’ (co-auteur H. Huizinga et publié dans European Economic Review) constitue la première évaluation empirique pour l’Europe des théories d’exportation fiscale. Lorsque la mobilité du capital est imparfaite et que celui-ci est détenu par des actionnaires étrangers, les Etats ont un incitant à hausser la fiscalité pour exporter la charge fiscale sur ces actionnaires. L’étude empirique trouve une relation positive robuste entre le degré d’actionnariat étranger et la charge fiscale moyenne, validant ces théories. Le cinquième et dernier chapitre ‘Are International Deposits Tax Driven ?(Co-auteur H. Huizinga et publié dans Journal of Public Economics) analyse l’impact de l’imposition de l’épargne et de la fortune ainsi que de l’échange d’informations fiscales sur les dépôts bancaires internationaux. Utilisant des données bilatérales confidentielles de la BRI, l’étude montre que ces variables fiscales ont un impact sur ces dépôts, suggérant qu’ils sont en partie effectués pour éluder l’impôt.<p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

This work entails a study of some of the schemes that are employed by country residents when companies and trusts are used as vehicles for investing in offshore tax-haven and low tax jurisdictions so as to avoid taxes. The study also entails a critical analysis of the effectiveness of the some of the laws in South Africa that curb such offshore tax avoidance schemes. Similar laws in the United Kingdom and in the United States are analysed in order to come up with some recommendations that could be considered for possible reform of the relevant South African laws where they are found wanting. Since offshore tax avoidance is an international issue, the effectiveness of the recommendations of some international organisations in preventing the depletion of countries' tax bases are also analysed. / JURISPRUDENCE / LLD

Abstract in English, Afrikaans and Zulu / In 2016, Zimbabwe introduced specific transfer pricing legislation to prevent abusive tax strategies by taxpayers. This study uses a qualitative interpretive inquiry to assess the adequacy of the new transfer pricing regime. This study contributes to the body of knowledge in that it explores transfer pricing as a tax avoidance tool, a concept that is at its nascent stage in academic taxation literature. Furthermore, it addresses a methodological gap by employing a qualitative inquiry in an area that is predominated by quantitative research. Indepth interviews and document review were used to gather data, and deductive content analysis was employed with the aid of ATLAS.ti 8™. This study confirms previous findings that tax consultants play a significant role in the compliance decisions of Multinational Enterprises (MNEs) through the examination of the exploitative strategies practiced by these MNEs. The comparison of the OECD and UN transfer pricing guidelines in search for the applicability of international guidelines to Zimbabwe’s specific needs helped uncover the contemporary dilemmas in global standards versus domestic standards. This study responds to the knowledge gap regarding the transfer pricing phenomenon in Zimbabwe through the lenses of an under-explored three-layered rationality concept; legal, implementation and exploitative rationality. The argument maintained in this study is that this rationality trichotomy is a useful lens to understand transfer pricing as a tax avoidance tool, and that international standards are not universal and so each country’s unique situation should be addressed at a domestic level. / Zimbabwe het in 2016 bepaalde oordragprysingswetgewing ingestel om onregmatige belastingstrategieë deur belastingbetalers te voorkom. Hierdie studie het ’n kwalitatief-interpretatiewe ondersoek gebruik om die toereikendheid van die nuwe oordragprysingsregime te assesseer. Die studie lewer ’n bydrae tot die kennismateriaal omdat dit oordragprysing as ’n belastingvermydingsinstrument ondersoek, ’n konsep wat in sy kinderskoene in akademiese belastingliteratuur staan. Dit verken ook ’n metodologiese gaping deur ’n kwalitatiewe ondersoek te gebruik op ’n gebied wat deur kwantitatiewe navorsing oorheers word. Omvattende onderhoude en dokumentbeoordelings is gebruik om data in te samel en deduktiewe inhoudsontleding is met behulp van ATLAS.ti 8™ gedoen. Hierdie studie bevestig vorige bevindinge dat belastingkonsultante ’n baie belangrike rol speel by die nakomingsbesluite van multinasionale ondernemings (MNO’s), gebaseer op die ondersoek van die uitbuitende strategieë wat deur hierdie MNO’s beoefen word. ’n Vergelyking van die Organisasie vir Ekonomiese Samewerking en Ontwikkeling (OESO) en die Verenigde Nasies (VN) se oordragprysingsriglyne om die toepaslikheid van internasionale riglyne ten opsigte van Zimbabwe se bepaalde behoeftes te bepaal, het gehelp om die eietydse dilemmas van globale standaarde versus huishoudelike standaarde bloot te lê. Hierdie studie stem ooreen met die kennisgaping rakende die oordragprysingsverskynsel in Zimbabwe deur deur die lens van ’n onderontgindedrielaag-rasionaliteitskonsep, naamlik wetlike, implementerings- en uitbuitende rasionaliteit, te kyk. Die studie voer aan dat hierdie rasionaliteitsdrieledigheid ’n nuttige manier is om oordragprysing as ’n belastingvermydingsinstrumente te verstaan, dat internasionale standaarde nie universeel is nie en dat elke land se unieke situasie derhalwe op ’n huishoudelike vlak aangespreek moet word. / Ngonyaka we-2016, izwe laseZimbabwe lithula imithetho ebhekene ngqo nokwedluliselwa kwezezimali zentengiselwano ukuvimbela ukusetshenziswa ngendlela esakuhlukumeza amasu ezentela ngabakhokhintela. Lolu cwaningo lusetshenziselwa uphenyo olukhombisa ukuhumusha okuphathelene nobungaki bento ukuze luhlolisise ukudluliselwa kwesikhathi sokuphatha esisha ekudlulisweni kokubekwa kwamanani emali. Ucwaningo lunomethelela olwazini olufanele ngokuthi lihlola ukubekwa kwamanani njengethuluzi eligwema ukukhokhwa kwentela, njengomqondo osesesigabeni sokuqala ukukhula ezifundweni zemibhalo yezentela. Ngaphezu kwalokho, sikhuluma ngegebe elikhombisa indlela yokwenza izinto ngokusebenzisa uphenyo olukhombisa ubungako bento endaweni egxile ocwaningweni olubheke obungako bento. Ukuthola ulwazi ngalokhu kuye kwasetshenziswa izinhlolokhono ezijulile kanye nokubuyekezwa kwemiqulu yamabhuku, kanye nokusetshenziswa kokuhlaziya okuqukethwe okuphunguliwe ngokubambisana nosizo le-ATLAS.ti 8™. Lolu cwaningo luqinisekisa okutholakale ngaphambilini okubonisa ukuthi abeluleki bezentela badlala indima ebalulekile ezinqumweni zokuthobela imithetho yezinkampani zamazwe angaphandle ngokusekelwe ekuhlolweni kokuxhashazwa kwamasu enziwa yizo izinkampani zamazwe angaphandle. Ukuqhathaniswa kwe-OECD kanye ne-UN mayelana nokudlulisela imihlahlandlela yamanani ekufuneni ukusebenza kwemihlahlandlela yeziqondiso zomhlaba wonke ngokwezidingo zaseZimbabwe kusize ekwembuleni izinkinga zesikhathi esizayo emazingeni omhlaba ngokuhambisana namazinga ezindinganiso zomhlaba jikelele ngokuhambisana namazinga asekhaya. Lesi sifundo siphendula igebe lolwazi elimayelana nokwedluliselwa kwesimo sokubekwa kwenani lemali kwezezintengiselwano eZimbabwe ngokusetshenziswa kokubhekwa komqondo onezigaba ezintathu ongaphansi kwesilanganiso sokuhlola, okungumthetho, ukwenziwa kwakhona kanye nokuxhashazwa kwemiqondo. Lolu cwaningo luphikisana nokuthi lomqondo ongunxantathu yinto ebhekwe ngamehlo abomvu futhi ebalulekile ekuqondeni ukudluliselwa kokubekwa kwesimo sezemali njengethuluzi lokugwema ukukhokhwa kwentela, okusho ukuthi amazinga omhlaba awasiyo into efanayo nokuthi izwe ngalinye linesimo salo esingafanani nelinye okwenza ukuthi isimo ngasinye sibhekwe ngokwesimo sezinga lasekhaya. / Financial Accounting / D.
