My diploma thesis is focused on German taxation and the impact on Czech subjects exporting to Germany. The main aim of this thesis is to give Czech entrepreneurs useful and current information about the German taxation system and to show basic tax calculations. My thesis is split into four chapters. The opening chapter deals with the internal market of the European Union, its history and its four freedoms. The second chapter outlines export of goods and services from the Czech Republic to Germany, the possibilities of entering the German market and the basic steps to be carried out while entering this area. Second part of the thesis presents the practical part. The third chapter includes particular German tax system and the comparison of Czech and German tax systems. The last chapter is focused on the use of German tax system in practice, especially VAT and it gives (as well as the third chapter) practical taxation examples.

The aim of this thesis is to compare the benefits of the vehicle acquisition for businesses on a financial leasing or a loan. The theoretical part is in greater detail focused on the current state of the legislation on tax and non-tax obligations of businesses associated with the acquisition of a vehicle. The theoretical part also briefly describes two systems of EU countries which tax their cars based on the CO2 production. The practical part of this thesis is a model example which compares the economic advantages of a financial leasing and a loan. The results are also being compared with the current state of the Czech Republic market.

This thesis is dealing with development and analysis of value added tax rates and income tax rates in developed countries. Developed countries are member states of European Union and member states of Organisation for Economic Co-operation and Development. Standard value added tax rates are analysed during period 1971 till 2011 for both formations with following comparison. The development of corporate tax rates is observed from 1981 to 2011 again for both formations with comparison afterwards. For the same period of time are analysed free marginal rates of personal income tax but only within OECD. Next can be found analysis and comparisons of rates mentioned above from seven chosen states including the Czech Republic. In the final part, the development of tax rates in chosen states with respect to the development of GDP in these states is presented. The development in chosen states is surveyed for the period 1981-2011.

The topic of this master thesis is the German tax system which is a relatively complicated entity. The aim of this thesis is to provide the updated and practical information useful for the Czech exporters and for their business activities in Germany. The thesis consists of five chapters. The first chapter describes the main export features from the Czech Republic to Germany. Next chapter analyses the different legal forms of companies that can be set up in Germany. The third chapter presents the process of the tax harmonisation and co-ordination within the EU. Next two chapters create the practial part of the master thesis. Particular types of both direct and indirect taxes are object of the fourth chapter. Finally, the last chapter applies the theoretical knowledge gained from the previous parts of the thesis in form of examples and situations from the tax practice and real business life of the entrepreneurs who export their goods and services to Germany.

This diploma thesis focuses on the comparison of corporate tax in the Czech Republic and Austria. The theoretical part deals in general with the taxes and tax systems of both countries. The next part is focused on the analysis and comparison of corporate tax in the Czech Republic and Austria. This issue is further illustrated on the selected company for the tax period 2020.

This diploma thesis “Tax Harmonisation in the European Union” focuses on an assessment of current developments in the harmonization of the various types of taxes. It compares the pros and cons of tax harmonization versus tax competition. It assesses continuation of the harmonisation process feasibility and its consequences. It contains an overview of the implementation of harmonization measures into the tax system in the Czech Republic.

This master thesis is dealing with development and application of a model that employs fuzzy logic. The model is used to support a decision of a selected Czech company that plans to invest abroad and establish a subsidiary. Selected indicators determine an investment risk in all countries considered for the investment. The model was implemented in parallel in two systems: MS Excel and MATLAB®.

The diploma thesis deals with the tax system in the Visegrad Four countries, specifically with the determination of the corporate income tax base and their comparative analysis. The thesis provides characteristic of items involving the corporate income tax base in Hungary, Poland and the Slovak Republic. Subsequently, these items are compared, and the comparison also includes determination of the corporate income tax base in the Czech Republic. Further, the thesis also analyzes the impact of legislative regulations of the corporate income tax base on the tax base width, the effective tax rates and the tax revenue in these countries.

C’est le droit des entreprises en difficulté qui a permis de mettre en évidence la complexité que pouvait revêtir la détermination de la date de naissance des créances. Or, celle-ci apparaît fondamentale en droit privé. Constituant le critère d’application de certains mécanismes juridiques, elle incarne l’existence de la créance et représente dès lors un enjeu pour toute règle de droit ayant celle-ci pour objet ou pour condition. Deux courants doctrinaux s’opposent, la thèse classique fixe la date de naissance au stade de la formation du contrat, tandis que des thèses modernes la fixent au stade de l’exécution du contrat. La thèse matérialiste, fondée sur le droit des entreprises en difficultés, fait naître la créance de prix au fur et à mesure de l’exécution de la contre-prestation. La thèse périodique, reposant sur une réflexion doctrinale quant aux contrats à exécution successive, fait renaître toutes les créances du contrat à chaque période contractuelle. L’examen des thèses moderne à l’aune des mécanismes juridique qui ne peuvent qu’incarner la véritable date de naissance de l’authentique créance aboutit à leur invalidité. La thèse classique se trouve donc à nouveau consacrée. Mais la résistance que lui oppose le droit des entreprises en difficulté ne peut reposer sur la technique d’une fiction juridique, car d’autres manifestations du même phénomène peuvent être mises en évidence en dehors de ce domaine. Un changement de paradigme s’impose donc pour résoudre le hiatus. Derrière ce phénomène persistant se cache en réalité une autre vision, une autre conception de la créance, la créance économique qui vient s’articuler avec la créance juridique dans le système de droit privé pour le compléter. La dualité des dates de naissance recèle donc en son sein une dualité du concept de créance lui-même, la créance juridique classique et la créance économique. La créance économique n’est pas un droit subjectif personnel. Elle n’est pas la créance juridique. Elle n’est pas autonome de la créance juridique et ne doit pas être confondue avec une créance née d’un cas d’enrichissement sans cause. La créance économique représente la valeur produite par le contrat au fur et à mesure de l’exécution de sa prestation caractéristique. Elle permet de corriger l’application ordinaire du concept de créance juridique par en assurant la fonction de corrélation des produits et des charges d’un bien ou d’une activité. Ses domaines d’application sont divers. Outre son utilisation dans les droits comptable et fiscal, la créance économique permet la détermination de la quotité cédée dans le cadre d’une cession de contrat, la détermination du gage constitué par un patrimoine d’affectation dans le cadre de la communauté légale, de l’EIRL ou encore de la fiducie, ainsi que la détermination du passif exempté de la discipline d’une procédure collective. Dans ces domaines, ce n’est donc pas la date de naissance de la créance juridique qui s’applique, mais la date de naissance de la créance économique. La cohérence du système de droit privé se trouve donc ainsi restaurée quant à la date de naissance de la créance. / It is the laws governing companies experiencing difficulties which have revealed the complexity of determining the dates of the origination of the claims. And yet this appears to be fundamental in private law. As it constitutes the criterion for implementing certain legal mechanisms, it epitomizes the existence of the claim and hence represents a challenge for any rule of law in which the existence of this claim is a goal or condition. There are two conflicting doctrinal currents: the traditional approach sets the date of origination at the stage of the formation of the contract, while modern approaches situate it at the stage of the execution of the contract. The materialistic approach, based on the law governing companies experiencing difficulties, staggers the origination of the price debt over the period of the execution of the service. The periodical approach, which relies on a doctrinal reflection on successive execution contracts, is that of the re-origination of all the claims under the contract at each contractual period. An examination of the modern approaches, under the auspices of the legal mechanisms which can only epitomize the true date of origination of the authentic claim leads to the invalidity thereof. The traditional approach is therefore once again consecrated. But the resistance constituted by the laws governing companies in difficulty cannot rely on the technique of legal fiction, because other manifestations of the same phenomenon can be identified outside this domain. Therefore, a change of paradigm is in order if the hiatus is to be resolved. Behind this persistent phenomenon lies in fact another vision, another concept of the claim: the economic claim which, interwoven with the legal claim in the private law system, supplements it. The duality of the dates of origination therefore conceals in its bosom the duality of the very concept of a claim, the traditional legal claim and the economic claim. The economic claim is not a subjective personal right. It is not a legal claim. It is not autonomous of the legal claim and must not be confused with a claim originating in a case of unwarranted enrichment. The economic claim represents the value produced by the contract as the service which characterizes it is provided. It permits the rectification of the ordinary application of the concept of legal claim by ensuring the function of correlating the proceeds with the costs of a commodity or an activity. Its domains of application are varied. In addition to its use in accounting and fiscal law, the economic claim permits the determination of the portion transferred in the context of the transfer of a contract, the determination of the collateral consisting in a special-purpose fund in the context of a legal joint estate, a limited liability individual contractor or a trust, as well as the determination of the liabilities which escape the discipline of collective proceedings. In these domains, it is therefore not the date of origination of the legal claim which applies, but the date of origination of the economic claim. The coherence of the private law system is therefore restored as concerns the date of the origination of the claim.
