M.Comm. / The first objective of this dissertation is to establish whether wealth or capital taxes are relevant to South Africa. If the answer is yes, the further objective is to identify the various forms of capital and wealth taxes in order to determine which form of wealth or capital tax would be suitable in South Africa in the future (refer chapter 2). The second objective, once the form of capital tax for a future South Africa is identified, is to determine which assets or, in other words, which property will be subjected to such a tax (chapters 3-5). The third objective is to analyse the recommendations contained in the fourth interim report of the Katz Commission of Inquiry into certain 3 aspects of the tax structure of South Africa (hereafter, referred to as the Katz Commission) and to examine the effect of these recommendations on the inclusion of property in the deceased's estate which will be subjected to such a tax (chapter 5). The fourth objective is to provide the reader with two diagrams which will enable such person to determine: whether a deceased person's estate will be subject to estate duty in terms of the current Act 45 of 1955, as amended (hereafter, referred to as the Act); and what an estate consists of (chapter 6). The fifth objective is to provide the reader with a comprehensive alphabetical property checklist to enable such person to determine whether a specific asset should be included in the estate of a deceased person (chapter 6).

This Master's thesis deals with the theme of tax mix. The main goal is analysis of the Czech Republic tax mix development and its comparison to the EU member states during the years 1995 -- 2010. The first theoretical part is focused on the basic tax terms, which are related to the theme of the tax mix. These include tax, tax system, tax reform and tax quota. The following section reflects the structure and development of the Czech tax mix and the major reforms of the Czech tax system until 2010. The third part focuses on a comparison of the tax mix and its development with the EU member states. First, the proportions of specific taxes in tax mixes of the EU member states are compared and then the development of the Czech tax mix is compared to the development of the EU member states average tax mix. In conclusion, there are complete comparisons and predictions expressed in the development of the tax mix of the Czech Republic.

The first essay studies the Marginal Cost of Funds in the existence of tax evasion. We develop a general equilibrium model of tax evasion, including the expected utility of taxpayers and three different revenue-raising government policies. In this rich model environment, we analytically derive the marginal cost of funds (MCF) for the alternative policy instruments. We consider two main fiscal reforms: the revision in the nonlinear tax scheme and the changes in enforcement mechanism (the audit and penalty rates). First, we derive the MCF for the tax reform and find its key determinants. The derived MCF is greater than the previous ones since it includes a "risk-bearing cost" as well as tax distortion. The reform in enforcement mechanism generates MCFs in different forms. Two more MCFs with respect to audit and penalty rates are presented. Finally, we compare these three different MCFs in numerical example and provide some policy implications. The second essay explores optimal tax structure in the presence of status effect. When the consumption of certain goods affects one's social status, this externality creates two opposite effects in a society. Seeking higher status through “positional goods" gives individuals much incentive to supply labor but still allocates income for less “nonpositional goods" as well. In this case, differential taxes on positional goods work as corrective instruments to internalize the social cost stemming from status seeking. Furthermore, the differential taxes generate revenue that can be used to alleviate preexisting income tax distortion. Thus, the differential taxes on positional goods could give so called “double dividend." I develop a game-theoretic model in which each individual with a different labor productivity unknown to the others engages in a status-seeking game, and the government has a revenue requirement. Then I show that, under a condition in which utility is separable between positional goods and leisure, a revenue-neutral shift in the tax mix away from nonlinear income taxes towards positional-good taxes enhances welfare. Hence, the differential taxes on positional goods are necessary together with the nonlinear income taxes for an optimal tax structure. The third essay explores the impact of increasing capital mobility on regional growth and environment. I develop an endogenous growth model in which each local government competes against the others, to induce imperfectly mobile stock of capital into its region. Then I show that an increase in capital mobility generates “tax importing" due to which each locality experiences a higher growth rate and more degraded environment. That is, the increasing mobility dampens the capital tax and transfers the burden of pollution abatement to the locality. This finding supports the hypothesis of “race to the bottom" in environmental standards. Identifying a reduction in overall welfare of residents, I consider two alternative federal interventions in the model: uniform environmental standard and requirement of lump sum transfer or tax. Both of these federal instruments enhance the residents' welfare. / text

Trusts are subject to multiple fOl1lls of legislative regulation dealing with taxation and governance. Trusts were widely used by planners as taxavoidance shelters. Tax legislation was amended to subject trusts, other than special trusts as defined, to the highest income tax rate of forty percent, in tel1llS of section 5(2) of the Income Tax Act, 58 of 1962. The inter vivos trust is also subject to a wide range of anti-avoidance measures, including those contained in sub-sections (3) to (8) of section 7 of the Income Tax Act and Part X of the Eighth Schedule to the Act, as well as the general anti -avoidance measures in section 103. These measures impact negatively on the use of trusts for estate-planning purposes. The research objective was to evaluate the use of testamentary and inter vivos trusts for estate-planning purposes and to develop a holistic estate-planniD.g model incorporating these planning instruments. Both the testamentary trust and the inter vivos trust were evaluated against broad principles of effective estate planning and the taxes and duties applicable to them. The research also reviewed the writings of financial planners on various techniques and models used for estate planning, as wells as case studies documented in the literature. The research developed and evaluated holistic estate-planning models incorporating testamentary trusts and inter vivos trusts, respectively. By neutralizing the effects of various taxes and duties, it was demonstrated that it is possible to develop an estate plan that satisfies most of the requirements of effective estate planning.
