The content of this diploma thesis is the analysis of the systems of consumption taxes in the European Union and in South America. The main aim of this thesis is to test the hypothesis that the proportion of consumption taxes in the total tax revenue is higher in the less developed countries - specifically in South America, than in the European Union member states. The hypothesis is verified by the comparison of the structure of the total tax revenues and consumption taxes in the EU and in South America. The thesis describes the consumption taxes and the harmonisation of it in both areas and the ways of combating tax evasion used in these two areas.

This dissertation analyses local reverse charge on VAT and guarantee of the customer as the tools the Czech Republic introduced in its fight against tax frauds and shows obstacles which could arose during its transition into the Czech tax system.

The subject of this thesis is an implementation of a reverse-charge mechanism on selected goods, more specifically waste and scrap, which are listed in Annex no. 5 of the Act no. 235/2004 Coll., on Value Added Tax. The reverse charge mechanism, as is evident from the title, is the transfer of VAT obligations of provider to the recipient of taxable transactions. The reverse charge mechanism is not only in the Czech Republic, but also throughout the European Union, introduced as a measure against VAT frauds. The main objective of this thesis is an analysis of the impact of the reverse-charge mechanism on waste and scrap in the Czech Republic covering the period from 1. 4. 2008 to 31. 3. 2015. This analysis is shown that the implementation of the reverse-charge mechanism eliminated fictitious deliveries of waste and scrap related to carousel frauds within trades of Czech Republic and EU 28. The estimation of tax evasion in the period from 1. 4. 2010 to 31. 3. 2011, the period just before the implementation of the reverse-charge mechanism, is in the amount of CZK 1,561,278,000.

The diploma thesis is dedicated to tourism. It examines historical development and legal framework of tourism, attemps to discuss the accounting, tax and tour prices calculation. The focus is nevertheless on accounting of the arrangement of sale of tours with the posibility of comission capturing, accounting of advances or cancellation fees, accounting transactions denominated in foreign currencies or vouchers viewing. It describes value-added tax as well as income tax. Attention is paid to the company Čedok in order to show some areas of financial statement of this company together with general accounting principles.

This article analyzes the definitions of the main taxable events for the Value-Added Tax (VAT) based on a comparative approach to thelegislation of different countries (Spain, Mexico, Chile, Colombia, Argentina and Peru). In this regard, it analyzes which legislations offer definitions according to the principles of generality, fiscal neutrality and legal certainty for VAT. Moreover, it points out that the VAT systems of those countries do not require as a condition for the configuration of the taxable events that the transactions involve a «value added» or a final consumption. In the specificcase of «supplies of goods», the VAT systems have a similar definition of the taxable event, although there are a few differences. However, in the case of«supplies of services», which is the most important taxable event for VAT, there are important differences at the time each country defines it. This is not a desirable effect for the international trade of services, since the lack of harmonization produces double taxation or double non taxation. / El trabajo aborda la definición de los hechos gravados principalesen el Impuesto al Valor Agregado (IVA) en el derecho comparado (España, México, Chile, Colombia, Argentina y Perú), evaluando qué legislaciones proponen una definición conforme a los principios de generalidad, deneutralidad y de seguridad jurídica. Destaca que ninguna de las legislaciones exige como condición para la configuración de los hechos gravados que setrate de transacciones que generen «valor agregado» o que se trate de bienes o servicios susceptibles de consumo final. En el caso de la venta de bienes muebles, hay coincidencia en la definición del hecho gravado, aunque con matices de diferencia. En cambio, en la definición de servicios, que es la hipótesis más importante del impuesto, hay grandes diferencias entre las legislaciones. Ello definitivamente no es deseable, considerando el comercio internacional de servicios, por cuanto la falta de armonización produce fenómenos de doble imposición y doble no imposición.

Image-based quantifications of visceral adipose tissue (VAT) volumes from segmented VAT areas are increasingly considered for risk assessment in obese patients. The goal of this study was to determine the power of partial VAT areas to predict total VAT volume in morbidly obese patients (BMI > 40 kg/m2) as a function of gender, age and anatomical landmarks. 130 morbidly obese patients (mean BMI 46.5 kg/m2; 94 females) underwent IRB-approved MRI. Total VAT volumes were predicted from segmented VAT areas (of single or five adjacent slices) at common axial landmark levels and compared with the measured ones (VVAT-T, about 40 slices between diaphragm and pelvic floor). Standard deviations σ1 and σ5 of the respective VAT volume differences served as measures of agreement. Mean VVAT-T was 4.9 L for females and 8.1 L for males. Best predictions were found at intervertebral spaces L3-L4 for females (σ5 = 688 ml, σ1 = 832 ml) and L1-L2 for males (σ5 = 846 ml, σ1 = 992 ml), irrespective of age. In conclusion, VAT volumes in morbidly obese patients can be reliably predicted by multiplying the segmented VAT area at a gender-specific lumbar reference level with a fixed scaling factor and effective slice thickness.

The aim of this paper is to illustrate the recent situation of the VAT system in China, including its problems as well as reforming trends within it, in order to provide promising further research paradigms. The research methods adopted exploratory studies to find out the major problems of the VAT system. To clearly describe the problems, statistical analyses are performed and quantitative data is used to supplement the qualitative analysis. Moreover, to discuss the problems of the Chinese VAT system, this paper compares the Chinese VAT system with other countries, especially Taiwan, in order to give a detailed description of its problems. The results of this study show that the Chinese government only concentrates on how much revenue it can collect but ignores tax equity and tax neutrality as well as low income groups. The conclusions of this study show that the problems of the imperfect VAT system and the changing economic conditions of China have resulted in double taxation, an unfair tax burden, an unreasonable threshold, complex VAT rates, and a gradual worsening of local fiscal conditions. In comparisons between GDP growth and VAT revenue growth, VAT revenue growth exceeded the GDP growth. One of the major reasons is rapid economic growth. Other reasons are that price indices increase every year and, also, China adopts gross income-type VAT which results in double tax on capital investment. Another probable reason is an increased effectivity and efficiency of China’s tax administration. Analysis of these problems shows that the Chinese government needs to improve not only its VAT system but also the taxation system and its fiscal system.
