Thesis (MAcc)--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: In November 2006 section 103(1) of the Act was abolished and replaced by a new Part IIA, containing sections 80A to 80L, which targets impermissible tax avoidance arrangements. Section 80A(c)(ii) introduced a new concept to the South African tax law: a misuse or abuse of the provisions of the Act, including Part IIA thereof. The objective of this study was to establish the origin, meaning, application and effect of section 80A(c)(ii) of the Act. The evolution of section 80A(c)(ii) was therefore examined where after the enacted version was analyzed. It was essential to determine the origin of section 80A(c)(ii) in order to establish some point of reference from which inferences could be drawn as to the possible application and effect thereof. Case law, practice statements and articles relating to its proposed root was then examined. A ‘misuse or abuse’ of a provision, it was found, implies, frustrating or exploiting the purpose of the provision. This contention was confirmed by existing Canadian precedent. Such an interpretation, however, has a strong resemblance to the words in which the draft version of section 80A(c)(ii) was couched. It is therefore in contrast to the presumption that different words (in the enacted version) imply a different meaning. The precise meaning of the words ‘misuse or abuse’ is thus still elusive. It was established that section 80A(c)(ii) has its roots in section 245 of the Canadian Act. Section 245(4) was regarded as an effective comparative to section 80A(c)(ii) as it also contained a so-called misuse or abuse rule. The application of this rule in the Canadian tax environment required the following process: - Interpret (contextually and purposively) the provisions relied on by the taxpayer, to determine their object, spirit and purpose. - Determine whether the transaction frustrates or defeats the object, spirit or purpose of the provisions. Section 245(4) had the effect of reviving the modern approach (a contextual and/or purposive theory) to the interpretation of statutes in Canada. Reference to the ‘spirit’ of a provision (above) was found not to extend the modern approach to statutory interpretation: it does not require of the court to look for some inner and spiritual meaning within the legislation. As section 245(4) was regarded as an effective comparative to section 80A(c)(ii) it was contented that it would have a similar effect, than that of its Canadian counterpart, on the approach to statutory interpretation in South Africa. However, it was established that a modern approach to statutory interpretation was already authoritative in South Africa. This finding led the author to the conclusion that section 80A(c)(ii) could at best only reinforce the case for applying such an approach. Such a purpose for section 80A(c)(ii) was however found to be void in the light of the Constitution of the Republic of South Africa, which was enacted in 1996, and provides a sovereign authority for the application of the modern approach. It was also found that the practical burden of showing that there was a ‘misuse or abuse of the provisions of this Act (including the provisions of this Part)’ will rest on the shoulders of the Commissioner, notwithstanding section 82 of the Act. / AFRIKAANSE OPSOMMING: Artikel 103(1) van die Inkomstebelastingwet is herroep in November 2006 en vervang deur Deel IIA, bestaande uit artikels 80A tot 80L, wat daarop gemik is om ontoelaatbare belastingvermydingsreëlings te teiken. Artikel 80A(c)(ii) het ‘n nuwe konsep in die Suid-Afrikaanse Inkomstebelastingreg ingebring: ‘n misbruik of ‘n wangebruik van die bepalings van die Wet, insluitende Deel IIA. Die doel van hierdie studie was om die oorsprong, betekenis, toepassing en uitwerking van artikel 80A(c)(ii) vas te stel. Die ontwikkeling van artikel 80A(c)(ii) is daarom ondersoek waarna die verordende weergawe daarvan geanaliseer is. ‘n Sleutelaspek van die analise was om die oorsprong van artikel 80A(c)(ii) vas te stel. Hierdie oefening het ‘n verwysbare bron daargestel waarvan afleidings rondom die moontlike toepassing en uitwerking van artikel 80A(c)(ii) gemaak kon word. Hofsake, praktyknotas en artikels rakende die voorgestelde oorsprong is vervolgens ondersoek. Daar is vasgestel dat ‘n ‘misbruik of wangebruik’ van ‘n bepaling neerkom op die frustering of uitbuiting van die doel van ‘n bepaling. Hierdie bewering is bevestig deur bestaande Kanadese presedent. So ‘n interpretasie is egter soortgelyk aan die woorde waarin die konsepweergawe van artikel 80A(c)(ii) uitgedruk is. Dit is daarom in teenstelling met die vermoede dat ‘n wysiging van die woorde (in die verordende weergawe) ‘n gewysigde betekenis impliseer. Die presiese betekenis van die woorde ‘misbruik of wangebruik’ is dus steeds ontwykend. Daar is bevind dat artikel 80A(c)(ii) waarskynlik sy ontstaan in artikel 245 van die Kanadese Inkomstebelastingwet gehad het. Artikel 245(4) van die Kanadese Inkomstebelastingwet is beskou as ‘n effektiewe vergelykende artikel vir artikel 80A(c)(ii), aangesien dit ook oor ‘n sogenaamde misbruik of wangebruik reël beskik. Die toepassing van hierdie reël in die Kanadese belastingmilieu vereis die volgende werkswyse: - Interpreteer (kontekstueel en doeldienend) die bepalings waarop die belastingpligtige steun, ten einde die oogmerk, gees en doel daarvan vas te stel. - Bepaal of die transaksie, deur die belastingpligtige aangegaan, die oogmerk, gees of doel van die bepalings frustreer. Artikel 245(4) het aanleiding gegee tot die herstel van die moderne benadering (‘n kontekstuele en/of doeldienende teorie) tot die interpretasie van wetgewing in Kanada. Daar is bevind dat die verwysing na die ‘gees’ van ‘n bepaling (hierbo) nie aanleiding gee tot die uitbreiding van die moderne benadering tot wetsuitleg nie: dit vereis nie dat die hof moet soek na die innerlike of geestelike betekenis van die wetgewing nie. Aangesien artikel 245(4) as ‘n effektiewe vergelykende artikel vir artikel 80A(c)(ii) beskou is, is daar aangeneem dat dit ‘n soortgelyke uitwerking, as sy Kanadese eweknie, op wetsuitleg in Suid Afrika sal hê. By nadere ondersoek is daar egter bevind dat ‘n moderne benadering tot wetsuitleg alreeds gesaghebbend in Suid Afrika is. Hierdie bevinding het die skrywer tot die gevolgtrekking gebring dat artikel 80A(c)(ii), in beginsel, slegs die saak vir die moderne benadering tot wetsuitleg in Suid Afrika sal versterk. Indien hierdie die doel is wat die wetgewer gehad het met die verordening van artikel 80A(c)(ii), sal dit egter niksseggend wees in die lig van die Grondwet van die Republiek van Suid Afrika, wat verorden is in 1996, en ‘n oppermagtige gesag bied vir die moderne benadering tot wetsuitleg. Daar is ook vasgestel dat die onus op die Kommissaris rus om te bewys dat daar ‘n ‘misbruik of wangebruik van die bepalings van hierdie Wet (waarby ingesluit die bepalings van hierdie Deel)’ was, ondanks artikel 82 van die Wet.

O imposto de renda, em seus mais variados aspectos e particularidades, tem se mostrado um dos temas mais complexos e debatidos pela doutrina especializada e pelos tribunais ao redor do mundo. No Brasil, jurisdição em que o Sistema Tributário Nacional encontra-se ampla e rigidamente arquitetado pela Constituição Federal, o tema ganha especiais contornos, dada a necessidade de fiel compatibilidade entre a legislação infraconstitucional e os limites minuciosamente desenhados pelo constituinte. A presente pesquisa pretende entrar nessa seara para abordar o intrigante binômio aspecto material e base de cálculo do imposto de renda das pessoas jurídicas. No que tange ao aspecto material, investigaremos o grau de influência da rigidez do Sistema Constitucional Tributário sobre a composição dos elementos que caracterizam a renda constitucionalmente tributável. Nesse mister, será necessário discorrer sobre as teorias que propugnam pela ampla liberdade do legislador infraconstitucional para estabelecer o significado de renda (teoria legalista) até aquelas que apontam pouca (ou nenhuma) autorização para construção do conceito de renda no âmbito infraconstitucional, eis que isso seria matéria eminentemente constitucional. E assim se fará para que, posteriormente, viabilize-se o cotejamento entre a renda constitucionalmente tributável e o lucro contábil apurado de acordo com a legislação societária, eis que, tradicionalmente, é esse o ponto de partida para a apuração da base de cálculo do imposto de renda das pessoas jurídicas. Para tanto, será preciso analisar as funções e os usuários da contabilidade, identificando a atual perspectiva e os critérios que guiam a elaboração dos relatórios contábeis. Feito isso, tratar-se á de responder a seguinte indagação: poderia o legislador tributário brasileiro adotar o modelo de dependência total, isto é, adotar o lucro contábilsocietário como base de cálculo do imposto de renda das pessoas jurídicas sem nenhuma correção ou limitação no seu processo de determinação, como acontece em alguns países? Em última análise, analisar-se-á criticamente se o lucro contábil, juridicizado que foi pelo Direito Societário e Tributário, confirmaria ou infirmaria o aspecto material do indigitado tributo a teor do Texto Magno. / The income tax, in its various aspects and particularities, can be considered as one of the most complex and discussed issues by specialized doctrine and courts around the world. In Brazil, a jurisdiction that the National Tax System is comprehensive and almost tightly provided by the Federal Constitution, the issue gains special contours, specially about the compatibility between ordinary legislation and the limits provided by the constituent. This study intends to going through in this matter in order to discuss the intriguing binomial taxable event (material aspect of taxable event) and taxable basis of corporate income tax. Regarding to the taxable event, this study will investigate the influence of the Constitutional Tax System on the composition of the elements that characterize the constitutionally taxable income. At this point, it will be necessary discuss the theories that advocate the wide freedom of ordinary legislature to establish the significance of income (legalistic theory) and those theories that advocate little (if any) authorization to construct the concept of income by ordinary legislature under the argument that this matter would be eminently constitutional. And it will be done in order to make possible the comparison between constitutionally taxable income and accounting income determined in accordance with Brazilian corporate legislation, behold, traditionally, it is the starting point for calculating the taxable basis for corporate income tax purposes. For that, we will need to analyze the functions and users of accounting, identifying the current perspective and criteria that guide the preparation of financial reports. After this, we will be able to answer the following question: could the Brazilian legislature adopt the tax total dependency model, i.e., the corporate accounting as the taxable basis for corporate income tax without any correction or limitation on your determination process, as happens in some jurisdictions? In essence, this study intends to perform critical analysis of if the accounting profit, which was provided for Corporate and Tax Law purposes, confirm (or not) the taxable event provided by Federal Constitution.

I study the role of heterogeneity and idiosyncratic risk in Macroeconomics, and their implications on problems of income taxation. In the first chapter, I study the effects of redistributive taxation in an incomplete market economy with heterogeneous agents and idiosyncratic risk. I focus on the role of distortions in labor supply decisions and the interplay of heterogeneity and uninsurable idiosyncratic shocks, conducting the first general equilibrium analysis of a Negative Income Tax (NIT). I show that a NIT is a serious candidate to replace the current income tax in the United States. I find that the optimal NIT has a marginal tax rate of 28% and a transfer of 10% of per capita GDP, roughly $4600. The welfare gains of replacing the current US income tax with a NIT are equivalent to a 6.3% increase in annual consumption in every state of the world. Low-ability agents, in the bottom quintile of the productivity distribution, benefit the most, while high-ability agents are worse off. A consequence of the reform is that the composition of the labor force changes, with high-productivity agents working more, in relative terms, than low-productivity agents. Finally, I find that the riskier the economy, the higher the welfare gains of the NIT as a provider of public insurance. In the second chapter, I study labor income dynamics over the life cycle and introduce a novel methodology that can detect the presence of patterns in the idiosyncratic earnings shocks and recognize economic forces in action. Using a sample from the Panel Study of Income Dynamics (PSID), I estimate a Bayesian Logistic Smoothed Transition Autoregressive model of order 1 (LSTAR(1)) with a rich level of heterogeneity in the innovations. I find that there is a life-cycle pattern in the earning shocks: before the age 29, young workers experience shocks with higher variance and a positive probability of lower persistence than older workers. A comparison with conventional models shows that an incorrect model specification introduces bias in the estimates. The proposed model can be easily approximated with a discrete Markov process. This means that this model can be used by macroeconomists to calibrate income processes.
