Zimmerman (1983) propõe que as grandes companhias devem apresentar alíquotas tributárias efetivas superiores às das pequenas companhias em decorrência dos custos políticos tributários. A aplicabilidade da hipótese dos custos políticos referentes à esfera tributária de Zimmerman (1983) ao Brasil pode ser defendida, uma vez que também se apresentam aqui muitos dos fatores institucionais que acabam por direcionar a atenção dos políticos e dos organismos regulamentadores/fiscalizadores para as grandes companhias. Sendo a questão de pesquisa do presente trabalho verificar se existe relação progressiva entre o tamanho das companhias brasileiras e a alíquota tributária efetiva, a hipótese metodológica adotada foi a de que existe relação regressiva entre a alíquota tributária efetiva e o tamanho das companhias. Tal proposição se pautou em Siegfried (1972) que defende que as grandes empresas, em função de contar com recursos financeiros e intelectuais superiores aos disponíveis aos pequenos contribuintes, acabam por reduzir, através do lobby e de estratégias de planejamento tributário, o montante de tributos a ser recolhido aos cofres públicos. O objetivo geral do trabalho foi traçar um diagnóstico de como se dá a relação, isto é, se esta realmente existir, entre a alíquota tributária efetiva e o tamanho das companhias. Dentre as restrições, cabe mencionar que o trabalho focou apenas o Imposto de Renda - Pessoa Jurídica (IRPJ) e a Contribuição Social sobre o Lucro Líquido (CSLL) e que foi pressuposto desta pesquisa que os valores das despesas tributárias apurados pelas companhias estão aderentes à legislação fiscal, ou seja, não foi utilizado nenhum mecanismo ilícito para redução de tais custos. O período analisado compreende os anos de 2006 a 2011 e a amostra foi composta por 3037 empresas distribuídas em 23 setores. Foi utilizada a técnica estatística de dados em painel, que permitiu trabalhar a base de dados sob duas perspectivas: temporal (within) e cross-section (between). Sob a perspectiva temporal, a única variável que impacta a alíquota tributária efetiva é o tamanho. Adicionalmente, o relacionamento dessa variável é inverso ao tamanho, sendo, portanto, possível afirmar que, no Brasil, quanto maior uma empresa, menor sua alíquota tributária efetiva. Pela análise cross-section é possível afirmar que impactam a alíquota tributária efetiva: ser a empresa listada na bolsa (capital aberto), controle estatal, sede localizada na região norte e nordeste e alguns setores de atividades. Foi evidenciada a relação positiva entre a alíquota tributária efetiva e ser a empresa de capital aberto, tal relação é justificada, visto que essas companhias passam a ser acompanhadas por investidores e analistas, o que restringe a atividade de planejamento tributário. Com relação à região de localização da sede existe a tendência de maior pagamento de tributos para empresas cuja sede esteja localizada na região norte e nordeste. Considerando que no período analisado ocorrem mudanças legislativas relevantes, também foi testada a ocorrência de quebra estrutural nos painéis com relação ao Regime Tributário de Transição (RTT), cuja hipótese foi rejeitada, sendo possível concluir que o RTT cumpriu com seu objetivo, qual seja manter a neutralidade tributária. / Zimmerman (1983) contends that major U.S. corporations pay effective tax rates which are higher than those of small companies, as a result of political costs. The applicability of the political cost hypothesis, within the scope of Zimmerman\'s study (1983), to Brazil, could also be defended since there are many institutional factors in this country that lead politicians and the regulatory/supervisory agencies to scrutinize large companies more closely. Accordingly, the objective of this study is to examine whether there is a progressive relation between the size of Brazilian firms and the effective tax rates. The methodological hypothesis adopted was that there is a regressive relation between the effective tax rate and the size of the firms. This proposition is based on Siegfried (1972) who defends that, since major corporations have access to greater financial and intellectual resources than those available to smaller taxpayers, these firms are able to reduce, through lobbying and tax-planning strategies, the amount of tax payable to the public coffers. The general objective of this research was to map the relationship, if it actually exists, between effective tax rates and company size. Among the limitations, it should be stressed that this work focuses solely on corporate income tax (IRPJ) and social contribution on net income (CSLL) and that the study assumed that the determination of tax by the firms is compliant with fiscal legislation, i.e. no illicit tax evasion mechanisms were used. The period under analysis is from 2006 to 2011 and the sample comprised 3037 companies distributed among 23 sectors. The statistical technique for panel data analysis was used, permitting the database to be analyzed from two perspectives: temporal (within) and cross-sectional (between). From a temporal perspective, the only variable that affects the effective tax rate is size. In addition, the relationship of the variables is inverse and, accordingly, it is possible to affirm that, in Brazil, the larger the company the lower its effective tax rate. Based on a cross-sectional analysis, it is possible to affirm that the effective tax rates of companies are impacted when they are: stock-exchange listed (publicly held), state controlled, headquartered in the North and Northeast regions of Brazil and operate in specific activity sectors. A positive relation was evidenced between the effective tax rate and companies that are publicly held and this relation is justified by the fact that these companies are closely scrutinized by investors and analysts, thereby restricting their tax planning activity. As regards location, companies whose headquarters are located in the North and Northeast regions tend to pay higher taxes. Considering that during the period under analysis, significant changes to tax legislation occurred, the occurrence of a structural break in the panel data, related to the Transitional Tax Regime (RTT), was also tested and the hypothesis was rejected, and it was possible to conclude that RTT fulfilled its objective, which is to maintain tax neutrality.

如何使企業所負擔之租稅成本降至最低之租稅規劃，對於企業的生存與競爭具有莫大的影響力。個案公司以境外公司之名義報價與接單，並透過OBU帳戶收受佣金收入，將利潤保留在境外公司，但營業費用卻於台灣公司認列，使得因三角貿易賺得之佣金收入是否歸屬於境外來源所得而免稅，一直為爭議性之話題。 　　為避免將利潤保留在境外公司而不匯回，擬於所得稅法修正草案中將決議分配股利時才認列投資收益，改成依照財務會計上之權益法認列投資收益。並配合響應政府提倡亞太營運中心計劃及經發會提出健全資金回流機制，增（修）訂促進產業升級條例第七十條之一及兩岸人民關係條例第二十四條第二項，並開放OBU得與大陸地區金融機構直接通匯。 　　根據以上結論，本研究提出建議如下： 　　一、對企業界之建議 　　企業進行國際租稅規劃時，應把握合法性、注重實質、評估規劃之成本效益及考慮相關法令變遷之風險等四項原則。 　　二、對政府修法之建議 　　　1.發展台灣成為營運總部之租稅配合措施 　　　　(1)加強簽署國際租稅協定 　　　　(2)建議評估營利事業所得稅由屬人主義改採屬地主義之可行性 　　　2.對租稅政策之建議 　　　　(1)反租稅天堂措施之建議 　　　　(2)重新檢討所得稅法等有關涉外法規之適用 　　　3.我國現行稽核制度的改進意見 　　　　(1)加強國際租稅人才的培訓 　　　　(2)提昇稅務稽查技術 　　　　(3)增強稽核人力素質 / Using case study method and by interviews with field experts, this thesis studies the application of OBU (off-shore banking unit) in international tax planning. Planning to decrease tax costs has long been an important task for multinational companies to compete in the international market. To avoid paying domestic taxes, companies can structure transactions by the name of offshore subsidiaries and receive commissions through their OBU accounts. Consequently, profits are reserved in the offshore companies but costs of running business are claimed in Taiwan's tax returns. Under certain circumstances, commissions earned from this kind of triangle trading are tax-free, causing substantial losses of tax revenues to Taiwanese government. The thesis discusses this controversial issue relating to commissions from triangle trading. 　　To encourage remitting back profits generated in overseas, the tax law for taxes on investment income should be changed. This thesis suggests the use of equity method for recognizing investment income for tax purposes. Further, the regulation on banking operations between Taiwan and China also needs to be revised to expedite the transfer of fund across the strait. The thesis suggests the opening of direct remittance between Taiwan's OBUs and China's banks. 　　In summary, in devising an effective tax planning, companies should take into account both tax and nontax costs, and keep abreast of the risks of changes in tax laws and governmental policies. As for the government to develop Taiwan as the headquarter of global operation, promotion of the international tax agreements is essentially important to help firms avoid double taxation. Further, to attract more international companies investing in Taiwan, the government should evaluate the feasibility and impacts of shifting the taxation principle of corporations from worldwide taxation to territorial taxation.

<p>This thesis deals with the legislative problem of thin and thick capitalization of subsidiary companies situated abroad. This kind of companies are often used for tax planning purposes, as means for transferring company profit from a high tax state to a low tax state. Today, the legislative flora around the world mainly focuses on the question"how low/high can the capitalization level of the company be, before thin/thick capitalization can be considered to be at hand?". Instead, this thesis raises the question"how far from the optimal capitalization rate is a probable capitalization level for a company, and can this be an alternative approach to legislation?". The object of the thesis is to point out possibilities, as well as obstacles, to this approach, but also to show a possible design of a regulation based on the approach. It is discussed whether the uncertainty in determining the optimal capitalization rate overthrows the theory behind the approach, or in fact strengthens it. Several advantages, but also a number of drawbacks, are shown. Hence, the conclusion of the study is neither in favor of, nor against, a regulation founded on the optimal capitalization rate, but rather an invitation to further discussion and calculations.</p>

Tax planning is a core service provided by tax practices of public accounting firms. Performing this service well is important to the firms, their clients and the tax professionals involved. This study experimentally examines the effects of supervisory advice on the judgment of tax professionals performing tax planning tasks of different complexity, in the presence of the tax contextual features of accountability and time pressure, and finds that such advice is not necessarily helpful to performance. The advice, task complexity and accountability literatures are used in framing arguments and developing hypotheses, which propose that the timing of advice and the complexity of the task interact, so that advice is not necessarily beneficial. The study also draws on the behavioral tax, audit and accounting literatures. Discussions with senior tax practitioners indicate that supervisory advice is usually given to tax professionals before they commence tax planning tasks. The results of this study support the hypotheses and demonstrate that this practice of giving advice may not improve performance in a tax planning task and may even be detrimental. First, the results indicate that the giving of advice by a supervisor should be conditional on task complexity. Supervisory advice is beneficial for a higher-complexity task but detrimental to a lower-complexity task. Second, the timing of when any advice is provided is important. Although advice is beneficial for the higher-complexity task, the results indicate that when advice is given before the tax professional commences the task it interferes with the processing of information and insightful judgments. The giving of advice after the tax professional has thought through the task and prepared a tentative solution results in better performance for this more complex task. / Accounting

The subject matter of the thesis is new as the phenomenon of the Box Corporation has not been the subject of a specialized investigation from the fiscal perspective before. A foreign subsidiary indirectly owned in a third country jurisdiction is in the thesis classified as a Box Corporation. The subject of the thesis is primarily to analyze and establish the following connections: the intended corporate objectives and ends and the modus operandi and the means that often require the Box Corporation as a necessary vehicle to attain those ends. The close connections between corporate law and tax law as intended legal results interdependent on one another. The application of the Box Corporation as an important vehicle for international tax planning by Swedish corporate groups on ever increasing competitive international markets and the special tax problems connected to the Box Corporation as it presents serious challenges to the pursuits for a consistent, neutral and undistorted Swedish corporate tax system. The thesis also investigates legislative and regulatory public reactions to the Box Corporation in the ways of CFC tax provisions, of denying tax treaty privileges by Limitation of Benefits clauses and of increasing domestic requirements on reportable transactions and international exchange of information and co-operation.

The present work researches the taxation and tax planning of foreign-invested holding companies in the People's Republic of China. The scientific field of the work is the science of Tax Management. The research is undertaken with the goal to deliver a profound presentation of the corporate taxation of such foreign-invested holding companies established in the PRC. Based on such presentation, internationally known tax planning methods are examined to find clues for valid tax-planning means and methods for such holding companies. The scientific approach is to be seen as content-analytical with a strong reference to the basics of corporate holding taxation as exercised in Austria. The author describes the legal nature of holding companies, as they exist in Austrian and Chinese law setting the focus on incorporated holding companies. The legal conditions of establishing a foreign-invested holding company in the PRC are explained and clues for the tax examination are presented. Based on the finding that the Austrian "Gruppenbesteuerung" offers a tax consolidation model, which allows the setting off tax results amongst qualifying members, the author researches the Chinese tax laws for a similar group-relief system. However, as the research shows Chinese law does not contain any form of tax group-relief regime for foreign-invested holding companies. Therefore, the work continues to research further tax facts and tax events of Chinese tax legislation for means that allow foreign corporate investors to efficiently structure their investments from a tax point of view. In order to conduct such a search of alternative tax planning clues the research, basically, follows the systematic of the balance sheet of corporations determining the taxation of the individual balance sheet items. Finally, the work hints to the coming introduction of a new Chinese enterprise tax law which may change the situation of the taxation and tax planning of foreign-invested holding companies in the PRC altogether.

O presente trabalho procura identificar e descrever as possibilidades da utilização de procedimentos de reorganização societária tais como fusão, cisão e incorporação como formas de planejamento tributário. As reorganizações societárias vêm sendo utilizadas freqüentemente com a finalidade de se reduzir o ônus tributário das empresas e, conseqüentemente, aumentar sua lucratividade. Primeiramente procurou-se descrever e conceituar os processos de reorganização societária, bem como seus aspectos formais e burocráticos. Na seqüência abordou-se a questão da elisão e evasão fiscal, com ênfase na Lei Complementar 104/2001. Ainda, discorreu-se brevemente sobre o planejamento tributário, suas definições, características e importância para as empresas. Após isso abordou-se a questão da interpretação econômica dos atos. E, por fim, tratou-se brevemente sobre o planejamento tributário e a reorganização societária sobre o ponto de vista ético. As principais conclusões acerca do estudo foram: a legalidade da aplicação da reestruturação societária como instrumento de planejamento tributário e a necessidade de profundo conhecimento da legislação antes da operacionalização destes processos, uma vez que é sutil a diferença entre elisão (forma lícita de planejamento tributário) e a evasão (forma ilícita de redução tributária). / This study seeks to identify and describe the possibilities of the use of reorganization procedures such as merger, division and incorporation as forms of tax planning. The reorganizations have been used frequently for the purpose of reducing the tax burden of enterprises and, consequently, increase their profitability. First we tried to describe and conceptualize the processes of reorganization, as well as its formal aspects and bureaucracy. Following addressed the issue of tax evasion and avoidance, with emphasis on Complementary Law 104/2001. Still, talked briefly about tax planning, their definitions, characteristics and importance for businesses. After that addressed the issue of economic interpretation of the acts. And finally, it was briefly about tax planning and corporate restructuring on the ethical point of view. The main conclusions of the study were: the legality of the implementation of corporate restructuring as a tool of tax planning and the need for deep knowledge of the legislation before the operationalization of these processes, since the difference is subtle elision (lawful tax planning) and evasion (illegally tax reduction).

This research examined the concept of base erosion and profit shifting in the context of tax schemes employed by multinational corporations. The objective of this thesis was to identify weaknesses within South Africa’s income tax legislation, based on these schemes, and further to propose recommendations to counter the occurrence of base erosion and profit shifting by multinational companies. The research also comprised of a limited review of current global and South African initiatives to address the problem of base erosion and profit shifting. It was concluded that there are a number of weaknesses in the definitions and provisions of the South African income tax legislation that need to be addressed in order to reduce base erosion and profit shifting. Brief recommendations were proposed in relation to each of the weaknesses, in order to address them.
