The goal of this diploma thesis is to analyze the evolution of the tax progressivity of the personal income tax in the Czech Republic in 1993-2010. The first part focuses on the interpretation of personal income tax and definition of terms such as a taxpayer, a tax subject, a creation and a modification of a tax base, rates and options for tax liability adjustments. The second part deals with methods for measuring tax progressivity with key focus on global indicators. In the third part the analysis itself is carried out. I measure the tax progressivity of the personal income tax by selected indicators (the Musgrave-Thin index and the Kakwani index). The Household Budget Statistics published annually by the Czech Statistical Office serves as input data. According to the results of this paper, tax progressivity of the personal income tax in the Czech Republic is low, but with increasing tendency.

This master thesis deals personal income tax, its developments in the year 2007-2017. The thesis follows the development of personal income tax on change of tax burden of model taxpayers in the monitored period. To achieve the main goal of this thesis, the basic concepts of tax theory, the structure of personal income tax and its legislation´s adjustment are mentioned in the theoretical part. And also the possibilities of assessing the individual tax burden of this tax. In the practical part the model income of employee and self-employed, are adjusted to the tax base, including the calculation of the tax from this basis. In addition, the thesis examines the burden of taxpayers through and effective tax rate and methods of measurement progressivity by using the rate of tax progressivity. The conclusion summarizes the results and reasons for differences in the tax burden of employee and self-employed persons in the monitored period 2007-2017. It also evaluates the results of tax progressive analysis in 2007,2012 and 2017.

The purpose of this master thesis is comparison of the tax burden of Czech a Swedish employees. The first part describes tax systems of both analyzed states focusing on the taxation of income from employment according to the 2016 legislation in order to successfully perform the calculations in the following sections. The second, practical part is dedicated to the comparison of selected indicators. It consists of two parts. The first is focused on the calculation of average effective tax rate for various income groups and various types of taxpayers. The next part compares values of redistribution indicators, which are interval and global progressivity indicators (Lorenz curve, Gini coefficient). The final section is devoted to the comparison of conclusions of this thesis with conclusions of thesis with similar subject, that have been successfully defended.

This thesis analyzes the redistributive impact of the individual income tax over the time. The aim is to analyze and compare the tax burden on taxpayers and the degree of progressivity from 2000 to 2010. During those ten years, several significant changes, regarding the components of individual income tax, had occurred. In particular, there was transition from the standard deduction from the tax base to the tax credits in 2005 and 2005, and then in 2008 a change in the tax base as so-called super-gross wage, the introduction of linear 15% tax rate and in the case of the social insurance to the introduction of the maximum assessment base for employees. In this thesis the requirements for personal income tax are described at first, with focus on equity and related redistribution and measurements of the tax progressivity. The second part of this thesis describes the various structural elements of the personal income tax and their changes in individual years. The final section contains both analysis of the impact of these changes on the average tax rate for individual taxpayers and the degree of progressivity and then comparison of the average tax rate and the degree of progressivity in these ten years.

The purpose of this master thesis is comparing the taxation of income of employees in the Czech Republic and Germany. The theoretical part is focused on describing the taxation of income of employees in both analyzed states. This part also includes an explanation of the social insurance system in both countries. The empirical part of thesis oncentrates on a comparison between the tax burden of Czech and German employees among various income groups and various taxpayer. The tax burden is then compared with the effective tax rate. The final section of this thesis compares values of redistribution indicators, such as indicators of interval and global progressivity (Lorenz curve, Gini coefficient.

The purpose of the thesis is to compare the taxation of the employee income in the Czech Republic and in Ireland with appropriate legislation of 2015. In theoretical part, I describe tax system of both states with an emphasis on taxation of income from employment. The theoretical part contains also a short summary of tax systems development. Practical part is divided into two different sections. First of them is focused on the calculation of effective tax rate for taxpayers in different types of households and the second one deals with the calculation of interval and global progressivity of tax in both countries, together with an analysis of income equality or inequality in society by using the Lorenz curve and the Gini coefficient. The calculations showed a progressive tax effects in both the Czech Republic and Ireland, with higher rate of tax progression and higher degree of income inequality in Ireland. From the perspective of effective income tax rates, higher tax burden is imposed in Ireland. The effective tax rate is on average 13.5 of percentage points higher than in the Czech Republic. This is also confirmed by the legal provision of the relevant tax legislation.

State and local governments play an important role in financing and delivering public services in the United States. In 2008, state and local governments collected 57 percent of total federal, state, and local revenue (Urban Institute and Brookings Institution, Tax Policy Center, 2009). The decentralization of fiscal responsibility has enabled a high degree of variation in state and local tax structures to emerge. This dissertation presents two empirical studies that extend the positive literature on state and local tax policy. The extant literature contains evidence of a direct relationship between voter ideology and state and local tax progressivity. However, the measures of voter ideology that were used either did not capture differences in the intensity of voter liberalism across states, did not vary over time, or were beset with other limitations. This study uses the measure of average voter liberalism developed by Berry et al (1998). I find that average voter liberalism is significantly and positively-related to progressivity. However, the effect is small in magnitude. The ethnic congruence between the poor and the non-poor is positively-related to progressivity and the effects are economically significant. The degree of tension between ethnic groups, measured with an index of ethnic residential segregation, is significantly and inversely-related to progressivity. Both variables are statistically significant even with average voter liberalism held constant. It is possible that the ethnic demographic context reflects aspects of voters’ redistributive preferences that are not captured by measures of ideology. Researchers have found relationships between states’ tax exporting capacities and the tax structures they adopt. Chapter 4 is the first study to examine the relationship between state tax exporting capacities and the business sales taxes. I find that the effective sales tax rate that governments impose on business purchases is not significantly influenced by a state’s capacity to export business taxes. It is, however, significantly and positively affected by a state’s ability to export taxes on households through the deductibility of state and local taxes under the federal income tax. A decrease in this offset is predicted to lead to an increase in the effective business sales tax rate, ceteris paribus.

The following article begins with the old and close relationship between labor rights and international trade, a relationship that has become more important given the creation of new instruments, mechanisms and sanctions. The labor chapter of the Peru-US Trade Promotion Agreement and its application can be analyzed from different perspectives. The following article sets its focus on three distinct facets: the principle of progressivity of social rights; the legal nature of free trade agreements; and two of the current promotional labor regimes in Peruvian legislation. The article references two complaints of non-compliance with the labor chapter presented by Peruvian unions during the period since the Free Trade Agreement entered into force. Finally, the report presents conclusions that aim to contribute to the debate on this subject. / El siguiente artículo parte de antigua y cercana vinculación entre Derecho del Trabajo y el comercio internacional, relación que en los últimos años ha recobrado importancia debido a la aparición de nuevos instrumentos, mecanismos y sanciones. El contenido laboral del TLC con los Estados Unidos y su aplicación se pueden analizar desde distintos ángulos, en el siguiente trabajo nos limitaremos a estudiarlo a la luz de tres elementos: el Principio de Progresividad de los derechos sociales, la naturaleza jurídica del TLC y dos de los regímenes laborales promocionales vigentes en la legislación peruana. Los incumplimientos a los que haremos referencia son los referidos a las dos quejas presentadas por organizaciones sindicales peruanas en el marco de los mecanismos de cumplimiento del TLC. Finalmente, se presentan algunas conclusiones que pretenden contribuir al debate sobre la materia.

The thesis analyzes and compares tax burden on employees in the Czech Republic and Belgium. The first part summarizes the tax systems of the two countries, and describes how to proceed in the calculation of their tax burden. The second part deals with the comparison of effective tax rates for different types of taxpayers. The third part discusses the tax progressivity in terms of local progressivity, which is measured by using provided intervals and determines for which income categories is the progressivity most important. Lorenz curve in the last part shows graphically global tax progressivity and redistribution of income in society. The Gini coefficient measures it. Final evaluation highlights the important ties between the two countries, compares with other countries of the European Union and its future development especially in the area of taxation of wages.
