Abstract Because of its unconstrained capability, tax negotiation system directed by the tax administration in general renders taxpayers and tax agent uncertain about the examined result of tax cases. The purpose of the paper is to investigate factors affecting tax agents¡¦ satisfaction on the tax negotiation system. In addition, we also examine the impact of tax agents¡¦ cognition and matching attitude to the tax negotiation system on the degree of satisfaction on the system. The research was conducted by distributing 520 questionnaires to subjects selected by purposive quota sampling from the tax agent of national tax administration of southern district. Among these 520 questionnaires, 444 valid subjects have been received. Our research results show that: 1. gender, category, age, education, experience, scale and county have significant influence on cognition, attitude and satisfaction. 2. if a tax agent has higher cognition on the tax negotiation system then his/her matching attitude to the system will also be higher which results in stronger satisfaction involvement on the system.

Vu la nature complexe de la matière fiscale et son lien étroit à un environnement évolutif, le litige entre contribuables et administration devient une réalité inéluctable. Aujourd’hui, la pratique fiscale révèle que la voie juridictionnelle n’est pas toujours la meilleure façon de satisfaire aux besoins des litigants. Sous cet angle, le fisc veut instaurer de nouveaux instruments de règlement du litige, dit modes amiables, pour des nouveaux rapports avec le contribuable. En effet, la DGI examine aujourd’hui les différentes dimensions de ses litiges avec les contribuables, dont le but est d’aboutir à une gestion participative. Pour ce faire, elle cherche à mettre en place une pratique qui fournit de nouvelles manières d’aborder les difficultés. Il s’agit d’une nouvelle approche qui se focalise sur les éléments les plus importants du litige, elle propose un mode de règlement amiable de style coopératif, visant d’abord à identifier les intérêts mutuels pour une solution consensuelle. Cette pratique non juridictionnelle du règlement de litige évolue très rapidement. Elle a suscité un débat passionnant au sein de la théorie du droit public, tant sur le plan du fond que sur le plan de la forme. Les spécialistes ont débattus en effet les différentes possibilités juridiques de l’intégrer dans les procédures et de la mettre en examen pour tester sa comptabilité avec le système fiscal. Au bout du compte, la pratique qui a été admise par la DGI est celle de règlement négocié du litige, aboutissant à une transaction. Cette évolution reflète la montée en puissance de l’autorité de la fonction consultative en matière fiscale. En pratique, cela entraîne l’invention des instruments administratifs ou juridiques propres à l’administration fiscale qui facilitent le mécanisme de règlement du litige. L’incorporation des pratiques amiables reconnaît l’intérêt croissant de faire face au litige, mais quelques améliorations restent encore à réaliser, car le mécanisme a besoin d’un appui législatif et juridique, mais aussi d’une véritable volonté d’éliminer tout litige de la part du contribuable. / Given the complex legal nature of the tax and its close connection to a changing environment in Morocco, the conflict between the tax administration and its users become an inescapable reality. The judicial process was and is the traditional tool to adjust, but the Moroccan tax practice today reveals that this route is not always the best way to meet the needs of litigants. From this angle, the Moroccan tax legislator wants to introduce new tax disputes resolution tools for new relations between the tax authorities and taxpayers. The Moroccan tax administration examines now the different dimensions of his disputes with the different categories of taxpayers. The long term goal is to achieve participatory management of disputes. To this end, the DGI seeks to put in place following the new instruments that provide new ways to see the disputes that may arise between different tax services and their users. The current approach focuses on the most important elements of the conflict between the administration of the taxpayer, and that impact on how to approach and manage. This approach offers alternative methods of settling tax disputes cooperative style first to identify mutual interests for a consensual solution. These non-judicial methods of settling tax disputes evolve very quickly in the Moroccan case. They aroused passionate debate in the theory of public law, both on the substance of the plan on the level of form. Moroccan specialists have indeed discussed the various legal possibilities of integrating them into the overall system of dispute resolution, which have been under investigation to test their compatibility with the tax system. The accepted and mastered by DGI modes are negotiated settlement of tax disputes techniques such as negotiation and transaction. Other collection methods and under different and innovative forms in tax matters are being explored to integrate into the system. This reflects the rise of the authority of the advisory function in tax matters. In practice, this leads to the invention of administrative or legal instruments to the tax authorities that facilitate dispute resolution mechanism. Thus, the incorporation of alternative dispute resolution recognizes the growing interest to deal with tax disputes, but some improvements are still to be made, since the mechanism needs a legislative and legal support in Morocco, but also a real willingness to eliminate tax disputes from Moroccan citizens.

The thesis deals with finding definition characters of agents as permanent establishments (dependent agents) available from publicly accessible sources, including its negative definition in comparison with the concept of an independent agent. The second part of the thesis analyses all possible and suggested ways of tax base creation, i.e. application of substitute methods of profit assessment and tax base enumeration from accounting profit or difference between revenues and expenses. Further this part of the thesis focuses on the issue of appropriateness of the Proposal for a Council Directive COM(2011) 0121 of 16 March 2011 on a Common Consolidated Corporate Tax Base (CCCTB) for dependent agent's purpose. Used methods include analogy, analysis, synthesis, deduction and comparison.
