The present diploma thesis is focused on the analysis and the assessment of the state of the art of legal regulations of rights and duties of the persons who participate in the administration of taxes in relation to basic principles of tax administration. The core legal regulation which is relevant for the theme under study is the tax rules that comprise a basic survey of principles applicable by the entities of the administration of taxes in practice.

Essence même des rapports sociaux, la réciprocité est le principe fondamental qui gouverne les échanges entre les êtres humains et qui permet de définir l’équilibre de leurs relations. Protéiforme et fonctionnelle, elle demeure une notion délicate à circonscrire puisqu’elle s’inscrit à la fois dans la coopération et la lutte, qu’il s’agisse de la sociologie ou du droit. Cet équilibre ne peut rimer avec égalité dès lors qu’il s’agit d’étudier les relations entre l’Administration et les usagers. En effet, les individus n’agissent pas sous couvert d’un voile d’ignorance et les Administrations préservent les intérêts de l’État. Le hiatus affiché, il est incarné essentiellement par l’unilatéralité et la légalité du droit fiscal. Le caractère réciprocitaire n’est pas exclu pour autant. Dérivé adapté du principe d’égalité, la réciprocité serait un concept juridique et anthropologique au service de chacun, en proportion. À l’origine des valeurs et des structures humaines, de l’organisation de la famille jusqu’à celle de la société, la réciprocité imprègne tant le système fiscal que des instruments plus particuliers. Conformément à sa double nature, elle peut revêtir la forme de la « vengeance » – compliance et vérification, défaillance et rectification… – à l’instar du droit international, mais également la forme de « l’alliance » - Chartes, contrôle, transaction… -, à l’instar du droit des obligations. Stabilisatrice, la réciprocité participe donc du renouvellement de ces relations à tous les stades des procédures fiscales – imposition, contrôle et contentieux – dans le sens d’un équilibre obligatoirement différencié, générateur d’échange de bons procédés dans la préservation asymétrique, ou simplement différée, des intérêts de chacun. / Essence of social relations, reciprocity is the fundamental principle which governs human exchanges and defined the balance of their relationships. Protean and functional, it remains a delicate notion, between cooperation and struggle, in sociology but also in law. This balance cannot rhyme with equality when we study public relations: people don’t act behind a veil of ignorance and Administrations must work for public interest. The hiatus displayed, it is embodied basically in the unilateralism and legality of tax law. The reciprocal character is not excluded from these relations; from equality, it could be the anthropological and legal concept, serving each one, proportionally. Source of the human values and structures, from the family organization to the society organization, reciprocity colours both tax system that more special instruments. In accordance with its double nature, it may be in the form of “revenge” – tax compliance and tax inspection, failure to fulfil tax obligations and tax adjustment... – like in international law, but also in the form of “alliance” – Charters, tax audit, transaction... – like in contract law. Stabilizer, reciprocity is related to the renewal of these relations at all stages of the tax procedures – taxation, control, litigation – in the sense of a necessarily differentiated balance, which leads to an exchange of goods in the asymmetric conservation, or simply deferred, of the interests of each one.

Revenue collection agencies across the world aim to maximise revenue collection by minimising tax noncompliance. The different types of tax noncompliance are collectively referred to as the tax gap phenomenon, which revenue collection agencies address by means of various enforcement approaches and capabilities. Much like any organisation, the resources required to execute these capabilities are finite and require accurate organisational decision-making in order to make optimal use thereof. Information technology, and specifically decision support systems (DSS), is critical in enabling this decision-making process. Using the Structuration Model of Technology, the information needs, demand and offerings of revenue collection agencies are explored given their objective of narrowing the tax gap phenomenon using DSS. Emphasis is placed on the manner in which IT is used to address taxpayer noncompliance, the way in which IT supports knowledge creation and subsequently also facilitate the decision-making process of tax practitioners, and also the different types of IT offerings made available to decision-makers in the form of DSS. In doing so, this research presents the results of a case study on the South African Revenue Service in which a conceptual decision support system framework is developed aimed at minimising the tax gap phenomenon. The research is conducted as a qualitative single case study and presented through a narrative analysis. The framework is systematically constructed as the research findings emerge and concluded by means of a framework validation and transfer ability test. The research result is a conceptual DSS framework acting as a reference point to other revenue collection agencies with the objective of addressing taxpayer noncompliance through DSS. / Jurisprudence / D.
