- 1 - Abstract The issue of income tax is a topic that is current, whatever the political organization of the country, because it is a fact significantly affecting the political, economic and social conditions, from many different aspects. Individual load, as well as corporate income taxes is one of the key elements that most impact on people and affect their economic behavior, social and political decision-making standard. Income tax in the tax systems is one of the most important taxes, because it is burdening the income of individuals and legal entities, tax payers. Through a greater or lower tax burden on personal and corporate income it is possible to use the legislation in the area of income tax and its setting, in the period of economic stagnation, as an instrument for economic recovery. In the area of tax systems and tax systems of specific countries in the last decade we recorded a relatively significant development. The shift, consisting mainly in the approximation of national tax laws, is in our legal system particularly evident after the enter of Czech Republic to the European Union in 2004. In connection with the gradual expansion of the European Economic Community, of the customs union, common market between Member States and European Union development into as we know it today, with 27 Member...

In this paper, we test one of the fundamental assumptions in the tax competition literature, namely, that a country's taxable income depends on the tax policies pursued in the domestic and in neighbouring countries. Based on a panel of annual data of 14 western European countries spanning the period 1982 to 2004, we show that the common trend in falling corporate income tax (CIT) rates can in part be explained by the existence of fiscal externalities in the form of international resource flows. Our results confirm the presumption put forward in recent empirical tax reaction function studies, that interdependent tax setting behaviour is evidence of tax competition. However, taxable corporate income is shown to react inelastically to domestic and to foreign tax rates. Thus, the observed rise in CIT revenues in Europe between 1982 and 2004 cannot be explained by the trend in falling CIT rates. Moreover, we find that large countries' tax bases are more responsive to neighbouring countries' tax policies, which is in contrast to the classic asymmetric tax competition literature.

EU har under lång tid sökt lösa de problem som finns på den inre marknaden avseende direkt beskattning. En rad riktade åtgärder har förverkligats genom praxis. Jämte riktade åtgärder har även kommissionen arbetat med en långsiktig lösning där bolag ska ges möjlighet att använda sig av en gemensam bolagsskattebas för hela unionen. Den 16 mars 2011 presenterade kommissionen slutligen ett förslag till direktiv om en gemensam konsoliderad bolagsskattebas.

This thesis consists of four independent essays grouped in two parts. The first part analyzes the possibility and duration of a Pareto-improving pension reform. The second part considers some economic issues related to the tax avoidance activities. The possibility and duration of a Pareto-improving pension reform.Many countries face large problems in supporting current pay-as-you-go pension systems arising from demographic changes leading to the situation when returns on capital exceed population growth. Inefficiency arises from implicit taxation on pension contributions. In a closed economy, it is even more destructive due to its negative impact on savings and capital accumulation. Although the transition to a fully funded system is a great improvement of the economy, its implementation entails several difficulties if Pareto-efficiency is required. The first essay, “The Possibility of a Pareto Improving Pension Reform in a Heterogeneous Economy”, demonstrates that Pareto-improving transitions from pay-as-you-go to fully funded pension systems nearly always exist. To demonstrate this, I classify existing theoretical results according to the type of reformed economy, the form of pension benefits, and the policy instruments used during the transition. Then, I show that intergenerational heterogeneity should no longer be considered as an obstacle when implementing Pareto-improving pension reforms. To maintain redistributive or insurance mechanisms supported by pay-as-you-go systems, I propose to replace inefficient social security with redistributive tax and transfer payments inside one generation. This would save the economy from the inefficiency related to the implicit taxes on pension contributions imposed by pay-as-you-go systems. The second essay, “Designing Optimal Pareto Improving Pension Reforms: A More Distorted Economy Can be Reformed Faster”, investigates the optimal Pareto-improving debt-financed transition from pay-as-you-go to fully funded pension systems. In particular, I examine the relationship between key parameter values characterizing the preferences, the technology and the size of the initial system, and the necessary time for a Pareto-improving transition. My finding is that a more distorted economy can be reformed faster. This result gives an additional explanation to the success of the Chilean reform, where an initial pay-as-you-go system was the largest and, at the same time, the most distorting.An Economy with Clever Tax Avoidance Providers.In the third essay “The Importance of Income Distribution for the Price of the Tax Avoidance Service”, I design a model with a clever tax avoidance provider, who maximizes a profit by setting the price for the tax avoidance services. Therefore, the price for the tax avoidance service is endogenously defined. In that setup, the change in income distribution is not less important than changes in the tax code, which together are responsible for the tax avoidance demand. The model has a wide range of applications. In particular, I analyze the relation between inequality and the collection of tax revenue. The paper shows that tax revenue as a percentage of GDP might grow with inequality when the tax code is not significantly changed. Moreover, higher inequality implies lower marginal cost of additional revenue. This assay also considers tax base broadening, providing examples where this leads to a reduction in tax revenue.In the fourth essay, “ Tax Avoidance as a Reason for Secession”, I provide an additional explanation for the intentions to secede related to expected changes in the tax codes after the ''break down of a nation''. To demonstrate my points, I use a tax avoidance model designed in the third essay, where active tax avoidance providers make a decision about the price and quantity of their services. Secession gives the avoidance provider the option of setting different prices in separate regions.  As a consequence, the price for the tax avoidance service may fall in the poorer region and the elite of this region would be able to avoid the tax, which is impossible in union. Moreover, regional separation may lead to tremendous changes in the shape of income distribution, forcing new governments to change the tax codes. Thus, the government of the richer region may reduce tax rates in order to enlarge the tax revenue collection. To avoid a breakdown of the state, the government should reduce inefficient spending and tax duties. Promoting democracy or increasing the political influence of poor households may reduce the tendency to separate. / Diss. Stockholm : Handelshögskolan, 2002

This thesis deals with the indirect support of research and development, and tax savings in the particular company.The main objective of this thesis processes the information and support for research and development. Selected costs are subject of tax deductible costs within booking. These costs are deducted from the proceeds during the calculation of the profit. The second time we deduct these costs as part of a deduction from the tax base for research and development. Selected costs incurred for research and development project may be deducted from the tax base twice.

The main aim of this graduation theses was to characterize the bad debt and is then analyzed in the reporting entity. The most important part of this graduation theses is aplication of lawful rectifying item and amortization of debts in practice and after that resulting effect on tax base and income range. After a complete analysis and mapping of debts can be stated that the company has an overview of overdue debts, records all borrowers and applied hedge funds. Also accounting entity should not fear to make up rectifying items to overdue debts because if they will be in step with law No. 593/1992 Sb. about backlog for finding the base of income tax it can have the only the positive impact for the base tax and high of tax as well.

The main target of my diploma work is the evaluation of the financial statements course and the statements in a certain company, the calculation of the income tax and the draft tax strategy for the business entity. At the beginning of the practical part I describe the individual ithems of the financial statements for the years 2010, 2011 and 2012. The following is findings profit, its subsequent transformation and the calculation of taxes of corporate income. The last part of the practical part is tax optimalization and design strategy. I suggested 3 options: tax optimalization by way of depreciation, the donations to good causes and employment of workers with reduced working capacity.
