電子化政府是現代政府知識經濟時代發展之趨勢。政府的服務能力可以藉由電腦、網路的使用而大大提升；然而，在我國各種朝向電子化政府的政策中，網路報稅堪稱為時間較長且涵蓋範圍較完整的計畫之ㄧ，自1997年開始試辦到現在已有九年，在這樣的長年實施之中，卻仍存近百萬的二維條碼申報系統使用家戶；在現階段的進程上是否只需多加過渡的步驟便可成功邁向稅務網路化的最終目標。本研究採質、量混合研究法。採行先問卷發放，探究民眾不願意跟隨政策而改變報稅工具的原因；再以質化訪談專家學者，交叉詰問提出標的團體在科技進步與政策變遷的過程中，是否能夠不被遺落在後，在政府帶領下提出解決之道。 綜合而言，無論是自量化或是質化的訪談之中發現，民眾不願意順服的因素不外乎政府使用錯誤的對策來因應政策問題；如對於民眾的慣性使用未加以重視民眾，以及當民眾已不信任政府之作為時，卻又強制性地施加壓力，引發民眾產生在適應上的困難；政府忽略了在二維的過程下可以提供的學習階梯以使民眾適應。民眾的不願意順服便展現於其對於政府的不信任與堅持其使用方式（二維條碼報稅）之上。正因如此，面對政府的作為無法解決問題，而自然形成在政府做為下不願意改變自我行為的失落標的團體，本研究即是指仍堅持使用二維條碼系統申報個人綜合所得稅者；其同樣必然會發生於現今各項電子化政府政策中。 正因為它的自然發生且面對正變遷中的政策，政府能做的便是建置基礎設施，讓網路報稅政策回歸自然的手來主導它，讓過渡與變遷的機制面對科技的進入，以民眾與政府的雙方面向加以權衡，政府僅是操槳的手，為出現失落標的團體的政策，提供快速演化至下一階段的輔助，增加其順服的條件，並加強誘因的提供上做出與市場相同的行銷動力。 政府保留二維條碼申報制度，不僅為不確定的網路虛擬時代提供具實體性的安全感，又可以是電子化的加速處理。當然這些都是在政策呈現變遷的過程中，所進行的取捨。當民眾要的不再是基於效率與服務的兼具時，報稅手段的思索就不再是一項重點。面對報稅政策的未來，為民眾的需求提供效率的服務應放在第一考量，接著是邁向科技的進程的基礎建設須建置完備，安全機制、人員在訊練等等，才是增進邁向全面網路實質申報的必需手段。 關鍵字：政策變遷、政策演化、政策順服、個人綜合所得稅、二維條碼。

A elasticidade da renda tributável despertou grande atenção recente, motivada pela perspectiva de estimar em conjunto todas as reações comportamentais a uma mudança no sistema tributário através de um único parâmetro, mensurando custos de eficiência e de bem estar suportados pela economia de forma relativamente simples. O trabalho aborda a utilização de medidas de variação de bem estar para avaliar mudanças na política tributária e faz uma resenha da literatura sobre a elasticidade da renda tributável, conceitos, características, vantagens e limitações. Um modelo de preferências é especificado para exemplificar a dimensão das reações à tributação e os custos de eficiência envolvidos, e discutir a viabilidade do emprego da elasticidade da renda tributável como parâmetro estrutural. / This study aims to analyse the social cost and behavioural responses due the taxation of earned income in Brazil using welfare concepts and the elasticity of taxable income with respect to the net of tax rate. The elasticity of taxable income has deserved great attemption and is a main issue in public economics research agenda. Under some conditions, it holds the perspectives of measuring efficiency costs of income taxation from a wide array of behavioural responses just estimating one single parameter. The study introduces the use of welfare changes measures for tax policy evaluation and reviews the concepts about elasticity of taxable income, its characteristics, advantages and limitations of use. We develop a model in which we show the dimension of responsiveness of taxpayers. Based on this model, we estimate the efficiency cost and excess burden of income taxation and discuss the use of elasticity of taxable income as a structural parameter.

This study uses aspects of time series methodology to model and forecast major taxes such as Personal Income Tax (PIT), Corporate Income Tax (CIT), Value Added Tax (VAT) and Total Tax Revenue(TTAXR) in the South African Revenue Service (SARS). The monthly data used for modeling tax revenues of the major taxes was drawn from January 1995 to March 2010 (in sample data) for PIT, VAT and TTAXR. Due to higher volatility and emerging negative values, the CIT monthly data was converted to quarterly data from the rst quarter of 1995 to the rst quarter of 2010. The competing ARIMA/SARIMA and Holt-Winters models were derived, and the resulting model of this study was used to forecast PIT, CIT, VAT and TTAXR for SARS fiscal years 2010/11, 2011/12 and 2012/13. The results show that both the SARIMA and Holt-Winters models perform well in modeling and forecasting PIT and VAT, however the Holt-Winters model outperformed the SARIMA model in modeling and forecasting the more volatile CIT and TTAXR. It is recommended that these methods are used in forecasting future payments, as they are precise about forecasting tax revenues, with minimal errors and fewer model revisions being necessary. / Statistics / M.Sc.

Thesis aims to map the developement of wages taxation in the period of 2003-2013 and to evaluate the impact of the tax on personal income from employment and function benefits to the taxpayers wit different levels of income in a variety of situations, particularly in the case of maintenance of one or more children. The aim was to identify how the changes in the Law on Income Tax had affected different income groups, which of them had been affected the most and how.

The main idea of this diploma thesis is to analyse benefits, which can be provided by employers to their employees with regard to the impact on the personal income tax base and corporate income tax base. The analysed employee benefits include tax and deduction benefits, whether they can be regarded as tax deductible expenses and whether they are included in the taxable income of an employee. The benefits provided in DELTA a. s. based in Kardašova Řečice were analysed. Their extent and impact on the tax base were examined in this company. The thesis also examines, whether it is appropriate to adjust the benefit system or not.

O presente trabalho parte da análise das normas que regem a tributação da renda no mercado imobiliário com a finalidade de possibilitar a identificação de um sistema jurídico dotado de princípios e valores próprios, que possibilite o estudo de suas normas de maneira destacada em relação às demais disposições que versam sobre a imposição da renda. Não se tem por pretensão a busca de uma autonomia das mencionadas normas; pelo contrário, o estudo parte da premissa de um único sistema jurídico, mas que pode ser estudado sob diferentes pontos de vista: um sistema que comporta subsistemas normativos, com valores e princípios próprios. Objetiva-se, assim, a identificação e posterior aproximação daquelas disposições que possuem fundamentos e princípios comuns, o que possibilitará a compreensão da extensão das previsões normativas a serem analisadas, bem como as opções efetuadas pelo legislador na produção legislativa. Antes de se efetuar o estudo das normas que versam sobre a tributação da renda imobiliária serão discutidos e apresentados os conceitos gerais necessários às análises que se seguirão. A limitação do legislador na produção legislativa é aspecto central no presente estudo. Entende-se que o sistema jurídico justo demanda uma coerência alcançada somente quando verificada a adequação valorativa das normas que o compõem e apresente unidade, por meio da observância de princípios e valores comuns, por essas mesmas normas. As normas que prevêem as imposições fiscais incidentes sobre renda no mercado imobiliário se prestarão de pano de fundo para a identificação de princípios que regem a tributação do imposto de renda nas diversas situações apresentadas. Serão, assim, objeto de análise a tributação do imposto de renda das pessoas jurídicas, tributadas pelo lucro real e pelo lucro presumido; a tributação especial das pessoas jurídicas sujeitas ao patrimônio de afetação; os rendimentos auferidos pelas pessoas físicas decorrente das atividades ligadas ao mercado imobiliário, tais como o ganho de capital na venda de imóveis e a tributação dos fundos de investimento imobiliários. Ao final da análise da legislação que versa sobre a tributação do imposto de renda nas situações acima mencionadas serão apresentados os princípios e valores escolhidos pelo legislador para a imposição da renda imobiliária. / The present arises from the analysis of principles which rule the taxation on the real estate market aiming the possibility of identifying a legal system endowed with principles and self-values and also providing an outstanding study of its rules with relation to the other provisions which deal with the income taxation. There is no intention of the search of independence from the aforementioned provisions, on the contrary, the study arises from the assumption of a unique legal system, which otherwise may be studied under different points of view, a system which involves normative sub-systems with their own values and principles. It aims, therefore, the identification and later approach to those provisions which own principles and grounds in common, providing that way, the understanding of the extension of the normative foresight to be analyzed, as well as, the legislator\'s altematives when making laws. Before the study of the principles which deal with the real estate income taxation, the general concepts needed to the analysis shall be presented and discussed. The legislator limitation to the law making shall be the central aspect of the present study. It is understood that a fair legal system demands coherence, which is just achieved when the appropriate principle values which integrate it are consolidated by the observance of the common principles and values of such principles. The rules, which provide the tax enforcement collected on the real estate income, shall be the grounds for the identification of the principles which rule the taxation on the income tax of the different situations herein presented. The corporation income tax, collected on presumed and gross profits, special corporation taxation liable to the \"patrimônio de afetação\", the earnings obtained by the individual persons regarding real estate businesses such as capital gain in property sales and the taxation on real estate funds of investments will, therefore, be the object of the analysis. After the analysis of the legislation which deals with the taxation on the income tax of the aforementioned situations, the principles and values enforced on real state earnings chosen by the legislator shall be presented.

The aim of this diploma thesis is the analysis and comparison of labour taxation in the Czech Republic and Bulgaria. After the introduction, in which the goal and methods of solving are defined, there are two chapters that describe theoretically tax systems in both compared countries with focus on personal income tax and social security systems. The following chapter is devoted to indicators of effective taxation of labour, which are used for international comparisons. Another chapter will describe the comparison of the effective taxation of labour based on the achieved results. There is also an interval and global progressiveness that are used to measure the progressivity of the personal income tax in the Czech Republic and Bulgaria. In conclusion, there is a summary of the findings and aims of this thesis.

The paper analyses whether various aspects of a country's tax system have a positive or negative influence on individuals' attitudes towards the future. These attitudes are measured by an analysis of Google search queries derived from Google Trends which allow constructing an online futureorientation index for a sample of 58 countries. There results of this analysis indicate that capital gains taxes and value added taxes discourage future-oriented behaviour. Also, high personal income tax rates at the lowest income brackets discourage, whereas - surprisingly - the top marginal rates could positively influence an individual's future orientation. The paper contributes to existing research in three ways: First, it expands the existing tax literature by providing evidence that taxes can influence very fundamental personal values, such as individuals' general attitudes towards their future. Second, it contributes to a vast body of cross-cultural studies on future orientation by introducing tax law. Third, by using Internet search patterns the paper introduces these large, automatically gathered data sets into scientific tax research, thereby opening the possibility for further research opportunities.

The aim of this thesis is to compare taxation of employee and self-employed in 2016. The thesis is divided into two parts, theoretical and practical research. In the theoretical part, there are defined terms and theoretical aspects of taxation. The practical part consists of comparison of taxation of employee and self-employed at different income levels. Taxation involves personal income tax, health insurance and social security.

The purpose of the master thesis is to compare the tax burden of employees in the Czech Republic and in the United States of America according to the legislation in 2016. The theoretical part is devoted to the description of tax systems, focusing on the taxation of income from employment. In the part United States I briefly mention the development of the tax system. The practical part consists of two chapters. The first one is focused on the calculation of the effective tax rate for taxpayers from selected types of households. The second one deals with global progressivity of the income tax. Equal income distribution in society is analyzed using the Lorenz curve and the Gini coefficient. The calculations indicate progressive tax effects both in the Czech Republic and in the United States with higher rate of tax progression and also higher inequality of income distribution in the United States. In the issue of effective rates of income tax is evident higher tax burden in the United States. Differences of total effective rates are decreasing between both countries.
