This diploma thesis deals with tax optimization of companies. The thesis is divided into two main parts - the theoretical and practical part. The introduction of the theoretical part describes the history of taxes, their basic characteristics and the importance of their collection for today's society. Subsequently, the tax system of the Czech Republic with a focus on value added tax and corporation tax is presented. The practical part deals with specific possibilities of optimization of the amount of corporate income tax and value added tax. The opening chapter of the practical part emphasizes the difference between tax optimization and tax evasion. Subsequently, the options for optimizing the income tax are presented - from the very start of business, through the optimization of the tax base, tax deductions and deductible items. In the case of value added tax, the work deals on one hand with the tax registration itself and on the other with the group tax registration. Work should provide comprehensive guidance for reducing tax burden on businesses.

The thesis is focused on the evaluation of the financial performance of the company GEFOS, Inc. The aim is to evaluate the financial performance and impact of the original recommendations, which the company has applied, from the previous bachelor thesis. Based on the findings, a successive financial development will be assessed together with further possible measures for economic growth of the company. The first part contains theoretical knowledge of the apparatus of a financial analysis and selected methods and analysis of macro environment. In the second part, which is based on the stated goal, the gained expertise is used in practice. The work also contains, based on the results of the analysis, a sectoral comparison that helps to illustrate the overall financial situation of the selected company.

This dissertation entitled The Economical Implications of Institutional Restructuring of Applied Czech Agricultural Research solves the issue of effectiveness of applied national agrarian research, which is financed from public funds. The purpose of this thesis is to describe the current basis of applied agricultural research funded by the governance, respectively those scientific institutions that are eligible for an annual institutional grant to long-term development. Describe their focus and structure of results. Another purpose is to look for possible reserves in the system and to propose the restructuring of national applied agricultural research in organizations established by the Ministry of Agriculture of the Czech Republic. I have focused on comparing the outputs of scientific institutions in the periods of science and research support programs since 2007. In the data evaluated by the research institutions, I have been using bases in the last five years. From the point of view of the effectiveness of applied agricultural research, I am using data from 1989, respectively 2003. I solved the chosen topic of the dissertation by progressive steps. First, I evaluated the individual research institutions in terms of their outputs within the announced programs of support for science and research. I was looking for the argument that there is a substitute in the form of a private research organization in the current system of public research institutions. Which I didn´t find. State established applied agricultural research is unique in its content. For a comprehensive view, I have analysed the structure and types of research results achieved in the announced support programs. Problematics was solved mainly by comparison analysis based on literature, data and their aggregated results. The economic and social policy impacts are processed on the performance of the agriculture - food industry complex in terms of gross added value, socio-demographic data about workers in the field and complex. The dissertation proposes a new organization structure of applied agricultural research established by the state. A system of the central agriculture research organization is designed on the base of the current geographical distribution on the territory of the capital city Prague and Brno. The solution provides a more complex use of the existing unused potential of agriculture public research organizations. At the same time the standard elements of modern management are applied. Research has shown that the current system of funding science and research, which prefer quantity rather than output quality, is a major failure. At the same time, the work has shown that there is a way-out from the current fragmented system of the organization of applied agricultural research while preserving its unique possibilities. The results of this work enable, in the case of political will, the realization of greater efficiency of applied agricultural research established by the state in the Czech Republic.

This thesis deals with problematic of non-monetary deposits into basic capital of new emergent capital companies per Czech legislation. It is divided into five chapters, four of them are theoretical and the last one is a practical example. Theoretical part deals with definition of capital companies, their authorities, basic capital and ways of founding. Part of accounting deals with evaluation of non-monetary deposits at the depositors and the acquirer and with disclosure of the assets in the balance sheet. The tax section focuses on all major taxes related to deposits. The application part summarizes theoretical knowledge on the example from practice. The main goal of the thesis is to contain the issue in a comprehensive way. Consider the legal, accounting and tax rules that are closely related to non-monetary deposits and show the impact of non-monetary deposits at the acquirer and the depositor.

Cette thèse vise à analyser expérimentalement une structure flexible et légère dans différents régimes d’écoulement, dont le régime cavitant. Un protocole expérimental a donc été mis en place afin de caractériser le comportement hydroélastique d’un profil NACA 0015 en polyoxyméthylène (POM) et de le comparer à un profil en acier inoxydable considéré comme « rigide ». Des mesures en écoulement subcavitant ont été réalisées : chargement hydrodynamique, contraintes, déformées statiques, réponse vibratoire et champ de vitesse ont été mesurés pour les deux matériaux. Enfin, une analyse vibratoire a été menée en écoulement cavitant. Ces mesures nous ont permis de constater que les déformées statiques du profil flexible sont similaires aux déformations observées sur une poutre encastrée : la flexion est la déformation principale et la torsion est faible. Toutefois les performances du profil flexible sont moins bonnes que pour un profil rigide : la portance diminue tandis que la traînée augmente. D’autre part, il apparaît que la dynamique du profil est contrôlée par l’écoulement. En effet, lorsque l’incidence du profil est proche de l’angle de décrochage, une fréquence liée au détachement tourbillonnaire apparaît sur les spectres de vibration des profils. Elle conduit à une réduction des fréquences propres liées à la flexion : si l’influence de cette fréquence sur le profil rigide reste faible à basse vitesse, sa proximité avec la fréquence propre du profil flexible conduit à un lock-in. Celui-ci se produit également en écoulement cavitant : lorsque la poche de cavitation devient instable, sa fréquence d’oscillation devient très énergétique et prend le contrôle de la dynamique du profil flexible. Le lock-in prend fin quand une supercavitation se développe autour du profil. Il conduit à une augmentation de la masse ajoutée au profil alors qu’elle devrait diminuer en présence de vapeur d’eau. / This work deals with an experimental analysis of a flexible and light lifting profile for various flow conditions, including cavitation. An experimental protocol was set up to study a flexible NACA 0015 made of polyoxymethylene (POM) and compare its behaviour with a foil made of steel, which is considered as rigid. The forces, strains, stresses and vibrations of the foils were measured, as well as the velocity field. Moreover, a vibratory analysis was performed in cavitating flow. The flexible foil behaves like a built-in beam : the deformations corresponds to predictions from the beam theory, with high bending and low twisting. These deformations imply lower lift and higher drag compared to the rigid foil. The vortex shedding frequency appears on the vibration spectra near stall. It increases with flow velocity and leads to a decrease of the natural bending frequency. But flexibility involves lower natural frequencies : the first bending frequency of the flexible foil is 3.5 times lower than the rigid one. This allows lock-in between the first bending frequency of the flexible foil and the vortex shedding frequency. Lock-in occurs in cavitating flows too : when cavitation becomes unstable, it oscillates with a frequency close to the bending natural frequency of the flexible foil. This lock-in ends when the cavitation number is low enough, what leads to a decrease of the cavitation oscillation frequency. In those conditions, the added mass of the flexible foil does not decrease with the cavitation number as the added mass of the rigid foil.

Paragraph 7(1) of the VAT Act provides for the charging of VAT at 14 percent on the supply of goods or services by a vendor in the course or furtherance of an ‘enterprise’, the importation into South Africa of goods by any person or the supply of ‘imported services’. The term ‘enterprise’ has been interpreted to require an on-going activity and therefore once off sales should be excluded. The sale must relate to enterprise activities, thereby excluding private sales. Furthermore the enterprise activities are required to be carried out in the Republic or partly in the Republic. Establishing whether the enterprise activities are carried out in the Republic remains a contentious issue as the VAT Act does not specify the minimum required business activities to meet this criterion. ‘Imported services’ excludes services imported for the purposes of making taxable supplies and the liability of accounting for VAT on ‘imported services’ lies with the recipient of the imported service. Supplies (imported services) which are chargeable in terms of s 7(1)(a) and supplies, which if made in the Republic, are exempt from VAT or zero rated. ‘Imported services’ definition requires services to be consumed in South Africa. Services offered outside South Africa therefore generally do not qualify as imported services even the South African entity benefits from such services, for example a training course attended in a foreign country. Technological developments in the field of e-commerce globally have required countries to examine VAT laws relating to e-commerce. Extensive research has been done by the OECD on this topic, with reports issued on recommendations of how e-commerce should be taxed. Most guidance issued by the OECD on taxing e-commerce relates to indirect electronic commerce, which refers to goods or services where ordering, payment and delivery occur on line. Distinction is drawn between taxation of business-to-business transactions and business-to-consumer transactions. The OECD suggests that the ‘reverse-charge’ or self-assessment method should be applied to the taxing of B2B transactions resulting in minimal compliance and administrative costs. It is further recommended that for B2C transactions place of consumption should be defined as the recipient’s usual jurisdiction of residence and that non-resident suppliers should be required to register and pay VAT in the jurisdiction of the consumer, as this would result in the most effective tax collection method. ‘Enterprise’ includes electronic services from a foreign supplier where the recipient is a resident of South Africa or where the payment originated from a South African bank account. The Minister’s regulation, which came into effect on 1 June 2014, includes the following items in the definition of electronic services: educational services, games, online auction services, miscellaneous services and subscription services. The South African VAT legislation draws no distinction between B2B and B2C supplies of electronic services. The reasoning behind this was to avoid situations in which private customers could pose as business customers in order to avoid the levying of tax. A review of the services currently included in the Minister’s regulation on electronic services indicate that services that would relate to B2B supplies have mostly been excluded from the regulation. Effectively the South African VAT legislation manages to indirectly exclude B2B supplies from the definition of electronic services and therefore achieves the objective of minimising the administrative burden on B2B supplies.

The aim of the thesis is to evaluate the performance of the company AGRALL Ltd., which sells agricultural equipment. This thesis is split into two parts. The first part describes the theoretical assumptions and used methods. The second part applies theoretical knowledge to the data of the selected company. At first, the performance is evaluated by traditional indicators of profitability and then by using the economic value added which is calculated according to the methodology of the Ministry of Industry and Trade of Czech Republic. The company data are compared with values of indicators for the sector and with the data of the selected competition to ensure better explanatory capability. At the end of thesis the findings are evaluated and improvements are recommended.

This thesis is focused on the implementation of the reverse charge mechanism on supplies of electricity and gas, which was imposed on these goods on 1st February 2016. The main aim of the thesis is to determine whether carousel frauds in our territory disappeared after the introduction of the reverse charge mechanism and to attempt to estimate the amount of tax evasion before the implementation. The other topics in the thesis include a description of principles of carousel frauds and measures adopted in order to eliminate them as well as an evaluation of the contemporary level of implementation of this mechanism in the Czech Republic and other EU countries. The analysis of foreign trade statistics has indicated a significant decrease in these figures as a consequence of a possible elimination of related carousel frauds. The estimation of the amount of tax evasion in the period of six months before the implementation achieved 1.05 billion CZK.
