本研究以2009年至2012年企業之財務報表中關於所得稅項目探討企業特性與財稅所得額差異之關聯性。實證結果顯示，應計項目較多的企業，其財稅所得額差異為正向關係。企業特性方面，獲利能力與銷貨成長率較高的企業，其財稅所得額差異較小，符合假說預期。另外，在控制產業特性後發現，電子業暫時性財稅所得額差異顯著高於非電子業，但電子業之投資抵減利益顯著高於其他產業，因而有較低之應納稅額。營建業之免稅財稅所得額差異顯著高於其他產業，符合我國稅法土地所得免稅之規定。最後，企業規模在永久性財稅所得額差異與暫時性財稅所得額差異都有不同的關係，在永久性差異中為負向關係，顯示出企業規模較大，較有資源進行降低應納所得稅的租稅規劃;反之，在暫時性差異中為正向關係，符合政治成本假說。應計調整項目愈多之企業，其財稅所得額差異具有正向之關係。 / Using a sample of Taiwan listed and OTC company, this research examines the relationship between firm characteristics and the differences in book-taxable income from 2009 to 2012. Empirical results show that firms with more accruals tend to have greater book-tax differences. From the perspective of firm characteristics, firms with greater profitability and sales growth rate tend to have smaller book-tax difference. The results are consistent with the expectation of the research hypotheses. Further, after controlling for the industry effects, the results show that the electronics companies have higher amount of temporary book-tax difference; however, they have greater investment tax credit than non-electronics companies, resulting in lower tax payables. In contrast, construction companies have higher tax-exempt book-tax difference than other companies, consistent with the provision of Taiwan’s tax law exempting capital gains on land transaction. Finally, the relationships between firm size and permanent or temporary book-tax income difference are different. Large firms tend to have a negative permanent book-tax difference, consistent with the notion that large firms own more resources for tax planning to reduce the tax payables. On the contrary, large firms tend to a positive temporary book-tax income difference, which is in line with the political cost hypothesis.

Based on this concept, it is necessary to analyze all existing taxation regimes in Brazil and for a better research conclusion, it will be analyzed three companies with distinct branches and areas. Legal entities, within certain rules, will be able to choose from available taxation forms, ie, Taxable Income, National Income Deemed and Simple. Currently taxes in Brazil are very relevant to legal entities cost and expenses composition, regardless the size the company presents itself. Therefore it is necessary to analyze alternatives that would fit better for a given entity, since each tax regime has particular characteristics, are quite different, and will provide advantages or disadvantages for each company given the system chosen. Thus, by the survey raised in the case study, it will be assessed the best taxation way for each type of activity the company plays, being a selling clothes business, an industrial company that manufactures textile products or a services provider in construction / O objetivo desta pesquisa é fazer um Planejamento Tributário que poderá auxiliar na busca de uma alternativa dentro dos aspectos legais à melhor ou à menor carga tributária. A partir desse conceito, é preciso analisar todos os regimes de tributação existentes no Brasil e, para melhor conclusão da pesquisa, serão analisadas três empresas com ramos e áreas distintas. As pessoas jurídicas, dentro de certas regras, poderão optar pelas formas de tributação existentes, ou seja, Lucro Real, Lucro Presumido e Simples Nacional. Atualmente, no Brasil, os tributos são bastante relevantes na composição dos custos e despesas das pessoas jurídicas, independente da empresa ser de pequeno ou médio porte, devendo-se, desse modo, analisar as alternativas, pois cada regime de tributação possui características próprias e bastante diferenciadas, e para determinadas empresas, a escolha do regime de tributação poderá ter vantagens ou desvantagens. Dessa forma, pela pesquisa levantada no estudo comparativo, será avaliada a melhor maneira de tributação para cada tipo de atividade que a empresa desempenha, sendo uma empresa comercial que revende roupas, uma empresa industrial que fabrica papéis e uma empresa de prestação de serviços na área da construção civil

本研究以我國上市（櫃）公司89年至92年財務報表資訊及營利事業所得稅申報資料進行實證研究，探討造成我國財務會計所得與課稅所得差異之原因及財稅差異與企業評價之關係。在探討造成財稅差異原因方面，實證結果顯示除折舊費用未達統計上顯著水準外，呆帳費用、投資損失、存貨跌價損失及負債比率與財稅差異呈顯著負向關係，而投資利得、證券期貨交易所得、出售土地增益、企業規模、資產報酬率、電子業及營建業與財稅差異呈顯著正向關係。在探討財稅差異與企業評價之關係方面，本文援用Ohlson模型進行分析，結果發現財稅差異殘差項與股價呈正向關係，顯示投資人視未預期之財稅差異可能具有傳遞未來樂觀之財務會計所得或可節省稅負支出之租稅利益等資訊意涵因而反應於股價之上。依據實證結果，本文發現獲利能力越好或規模越大的公司越有可能透過租稅規劃，減少租稅上之負擔，此發現可作為稅務主管機關未來選案之參考；又本文也發現財稅差異具有資訊意涵，然現今財務報表揭露所得稅相關資訊有限，因此本研究建議證券主管機關應適度加強企業所得稅相關資訊之揭露與規範。 / Using 2000 to 2003 financial statement data and tax return data of listed and OTC companies in Taiwan, this study explores the sources of difference between tax income and financial reporting income and the relationships between book-tax differences and business valuation. The empirical results show that except for depreciation expense, bed debt expense, losses on investments, loss due to market decline of inventory, and financial leverage are negatively related with book-tax differences. However gains on investments, gains on securities transactions, gains in land transactions, business size, return on assets, the electronics industry, and the building industry are positively related with book-tax differences. The results also show that the regression residuals of book-tax differences are positively related with stock prices. This means that investors regard unexplained residuals as future earnings or income tax savings which are then reflected on the stock prices. The empirical results indicate that firms with greater profitability or large firms have greater incentives to conduct tax-planning which tend to reduce taxable income relative to income for financial reporting purposes. Our findings provide evidence for the Taxation Agency when doing audit adjustments and lend support for book-tax differences contain information that is relevant to firms’ valuation. However, in practice disclosure of information about income tax in financial statements is still limited, thus restricting investors in estimating book-tax differences. The security authority should devise appropriate accounting policies to improve disclosures on firms’ income tax information.

By proposing objective parameters for assessing the limits which the tax legislation may modify the concept of profits, we construct a useful tool for endorse or refuse such modifications. For achieving this goal, the study investigates how the interpretation of tax law interacts with the legal presumptions and legal fictions / O objetivo deste trabalho é o de investigar e demonstrar cientificamente um método para avaliar a legitimidade jurídica da atribuição de efeitos quantitativos ao lucro contábil-societário pela legislação do Imposto sobre a Renda, para fins de apuração do novo lucro para efeitos tributários, o lucro real . Com a definição de parâmetros objetivos para avaliar os limites em que a legislação fiscal pode partir de um conceito ou um instituto de direito privado para atribuir-lhe efeitos que lhes altere a substância, espera-se criar um instrumento de justificação dessas modificações quando legítimas ou para a sua oposição quando contrárias à Constituição e a outros princípios legais positivados. Para atingir esse objetivo, o estudo adota como método a investigação sobre como se relacionam a interpretação do direito tributário com as presunções e ficções jurídicas, de modo a verificar os limites desses efeitos. Ao final, como resultado, propõe-se um método para avaliar a justificação ou refutação dessas tais modificações

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 thesis deals with the development of social insurance, specifically with health insurance and social security, from the standpoint of transfer of insurance-generated monies to the state budget. It presents the significance of social insurance in its current form and an analysis of the principal changes it has undergone in the last fifteen years. It particularly examines changes in the definition of participants in social insurance and changes in the use and structure of bases of measurement in individual insurance subsystems. This thesis also includes an analysis of these changes which seeks to analyze the past and potential impact of shifts in basic factors which influence the amount of money flowing from insurance to the state budget (such as minimum wage, average wage and number of paying participants) on individual participants in social insurance.

After accession to the European Union, tax issues acquired and are still acquiring an entirely new character. A new legal environment is forming both in the Czech Republic and in the European Union. Until now, only indirect taxes have been harmonised, with direct taxes having remained in the domain of each member state. However, we are now feeling pressure to harmonise this area as well. Cases concerning value added tax belong to those that are now most often being resolved in front of the European Court of Justice in Luxembourg. Cases regarding direct taxes are also becoming increasingly important. Will direct taxes be harmonized to the same extent as indirect taxes have? When potential investor is considering his investment into a company, he needs to match comparable figures. Definitely, one of the most important criterions is the amount of profit after taxation followed by payout of dividends. If there are different ways of taxation of corporations in various EU Member States, then there would be no possibility to compare corporations placed in various EU Member States objectively. Therefore, the aim of this thesis is, based on the research in the whole EU regarding taxation of corporations, to suggest a method how to harmonize taxation of corporations, which now prevents companies from trading in a single EU market, and also to minimize corporation’s costs of fulfilment of tax administration requirements of each Member State. This aim has been achieved through the following partial aims: .. An analysis of taxation of corporations in each of all 27 EU Member States, .. An analysis of proposals of the European Commission regarding harmonisation of taxation of companies, .. Suggestion of own method of harmonization of taxation of corporations in the EU. In conclusion, there are emphasized the contributions of this thesis to the science, to the practice and to education.
