This research explores this question in two different ways: first, from Legal Theory point of view, will be analyzed the formal institutions related with object, with especial attenction to the unconstitutional norm sanction; second, confronting all theoretical models, this research collected data from one of Brazilian High Corts (Superior Tribunal de Justiça) and from High Administrative Court for Tax Disputes (Conselho Administrativo de Recursos Fiscais) with the scope to get a qualitative diagnosis of judicial and administrative decision making in disputes envolving the same object of this dissertantion. From these premisses, was found a trend to assign biding effects to Supreme Court precedents related to tax issues, inserting a new normative expectation to be obeyed by Governement and taxpayers. So, without any legislative reform, any incidental Supreme Court colegial decision can modify res judicata state of right, allowing the interruption of the future effectiveness of such sentences / O presente trabalho tem por o objeto de pesquisa pretende, a partir da contextualização da teoria do direito e direito positivo vigente, estabelecer a resposta para a seguinte pergunta: É possível a cessação dos efeitos da coisa julgada de relações jurídicas continuativas em matéria tributária em face de superveniente decisão plenária do Supremo Tribunal Federal? Para tanto, divide-se o trabalho em duas partes. Na primeira parte, analisaremos os seguintes aspectos: a) enfoque da teoria do direito, onde se estabelecem as premissas teóricas que serão contextualizadas no curso de todo o trabalho; b) complementando as premissas iniciais desenvolvidas anteriormente, analisa-se sanção de inconstitucionalidade sob a ótica constitucional. Ainda estudaremos o modelo teórico difundido pela maior parte da doutrina que o contrapõe ao direito positivo nacional; c) em seguida, a partir do estudo sistemático da coisa julgada e da eficácia da decisão plenária do Supremo Tribunal Federal sobre as relações jurídicas tributárias, serão indicadas as premissas menores do trabalho. Na segunda parte, busca-se, a partir da coleta de dados dos repositórios de jurisprudência do Superior Tribunal de Justiça e Conselho Administrativo de Recursos Fiscais, estabelecer uma análise qualitativa do modelo decisório definido por aquele órgão. A partir das premissas articuladas, conclui-se que o ordenamento jurídico brasileiro, ao menos no que se refere à relação tributária, atribui um caráter vinculativo às decisões plenárias do Supremo Tribunal Federal. Tal caráter constitui verdadeira alteração do arcabouço normativo prévio, pois insere uma nova expectativa normativa que deve ser obedecida pela administração pública e os contribuintes. Logo, a superveniente decisão do STF possui o condão de alterar o estado de direito da sentença atingida pela coisa julgada, o que permite a sustação da eficácia futura da sentença, por meio da ação de modificação

This study investigates the impact of aspects of tax design on the operating costs of the tax system. The thesis focuses on the Australian and UK regimes for taxing the capital gains of individuals. It contends that the compliance burden faced by personal taxpayers and the administrative costs incurred by revenue authorities are directly influenced by the design of the capital gains tax ('CGT') regimes in each country. The study bridges the divide between theoretical analysis of CGT and empirical studies on tax operating costs. It uses a hybrid research design to test a series of hypotheses that emerge from a review of the literature and the experience of the researcher. It combines a technical analysis of the relevant Australian and UK legislative provisions (including an analysis of the policy and other background data that underpins those provisions) with empirical research on the views and experience of practitioners who are responsible for the operation of the legislation in the two countries. The results obtained from this combined methodology indicate that the operating costs of taxing capital gains in Australia and the UK are directly affected by the design of the legislative provisions. Moreover, the study outcomes indicate that operating costs in both countries are high (on a number of comparative measures), have not reduced over time, and are both horizontally and vertically inequitable. The research indicates that the primary factors that cause the high operating costs include the complexity of the legislation and the frequency of legislative change, together with record-keeping and valuation requirements. The thesis identifies specific legislative changes that would address operational cost concerns. These include the phasing out of the 'grandfathering' exemption together with the introduction of an annual exempt amount, and the rationalisation of business concessions in Australia; and the abolition of taper relief and its possible replacement with a 50% exclusion in the UK. More importantly, it seeks a more principled approach to the taxation of capital gains in both countries, and emphasises that legislative change can and should only be enacted with a full and clear understanding of the operating cost implications of that change.

Tax amnesties are government programs that typically allow a short period of time for tax evaders to voluntarily repay previously evaded taxes without being subject to penalties and prosecution that discovery of such tax evasion normally brings. Tax amnesties differ widely in terms of coverage, tax types, and incentives offered. A state’s Voluntary Disclosure Programme is another avenue available to taxpayers to assist them in resolving their state tax delinquencies. This programme is an on-going programme as compared to a tax amnesty, which is there for a limited time period only. The main goal of the research was to describe the tax amnesty and the voluntary disclosure programmes in South Africa and to assess their advantages and disadvantages. This thesis also discussed another form of voluntary disclosure programme, referred to as an Offshore Voluntary Disclosure Programme, which allows taxpayers with unreported foreign bank accounts, and presumably unreported foreign income, to voluntarily disclose their affairs. The study found that, due to tax amnesties, Government raises more tax revenue not only in the short run from collecting overdue taxes but also by bringing former non-filers back into the tax system for the long run. It was also found that, initially short-run revenue brought in from overdue taxes will be positive for the first amnesty and then decline each time the amnesty is offered repeatedly. The reason for the decline in revenue might be that tax amnesties provide incentives for otherwise honest taxpayers to start evading taxes because they will anticipate the offering of future amnesties, thereby weakening tax compliance. The costs associated with amnesty programmes include negative long run revenue impact and also that amnesty programmes reduce compliance by taxpayers in the long-run. In South Africa tax amnesties, especially the voluntary disclosure programme, are likely to be successful since they will increase the revenue yield and also bring non-filers back on the tax rolls.

The main objective of the study was to analyze the potential tax collection from the informal rental housing market in Zambia, using household level rental housing data collected for the Lusaka Urban District by the Central Statistical Office (CSO) as a basis for computation and extrapolation to the national level. This data was used to analyze household monthly expenditure on housing (rent), the total number of households in rented accommodation, and the tax regime applicable on rental income, to estimate the potential tax revenue that could be realized from this emerging sector. The estimates indicate that about K9.7 billion revenue could be collected on income from rental housing in Lusaka Urban District alone and a total of K83 billion nationally per annum. This represents about 0.4 percent of the country’s GDP in 2007. Compliance needs to be improved and legislation revised to ensure that the landlords are compelled to remit tax to the Zambia Revenue Authority. The current legislation makes enforcement and compliance difficult as it places the statutory tax burden on tenants, who are very mobile. It is, therefore, recommended that the landlord is made responsible for the payment of taxes due on rental income and that any compliance requirements be enforced against the real estate/property that is generating the income. This study also examines the performance of the presumptive taxation regime in Zambia The study uses data from the Zambia Revenue Authority on revenue collection from presumptive taxes which were introduced to capture income from the informal sectors. The presumptive taxes already introduced in Zambia include: base tax, advance income tax and turnover tax for minibuses and taxi operators. To analyze the performance of the presumptive tax regime, the study utilizes data on imports made by those not registered for taxes, to estimate how much revenue could be generated by imposing a 3 percent turnover tax on the value of their imports at importation. The analysis shows that the Zambia Revenue Authority increased revenue collection from K5.3 billion in 2004 to K33.5 billion in 2007. This improvement in revenue collection is far below the potential, however, which is estimated at over K501 billion on imports of unregistered traders alone. To collect this revenue and expand the tax base, the tax authority needs to improve the administration of advance income tax on unregistered importers, and raise the advance income tax rate to a level where the importer is indifferent between paying the advance tax at the border and paying turnover tax inland.

Bibliography: pages 133-135. / There is an administrative law relationship between the taxpayer and the Commissioner for Inland Revenue, (hereinafter referred to as 'the Commissioner') The basis of this relationship is that the Commissioner is required to collect tax and the taxpayer is required to pay the tax. In exercising his powers under the Income Tax Act No. 58 of 1962 (hereinafter referred to as the Act), the Commissioner has been conferred with discretionary powers. In this thesis, this administrative law relationship is examined with specific reference to the means of regulating the exercise by the Commissioner of his discretionary powers. There are a number of ways in which the discretionary powers of the Commissioner may be regulated. Generally discretion may be regulated by 'rule based administrative action' (1). This means that discretionary power is exercised subject to internal rules which state how discretionary power must be exercised. Another method of regulating the exercise of discretionary power is subsumed under the category of 'adjudicative techniques of decision' (2). The essence of the latter category is that the affected person participates in the decision which affects him. The exercise of discretionary power may be regulated furthermore if the Minister who has responsibility for the Department is required to be responsible for and account publicly for the actions of his subordinate. In this thesis, examples of rule based administrative action and adjudicative techniques of decision are examined.

Taxation statutes often provide opportunities for tax avoidance by taxpayers who exploit the provisions of the taxing statute to reduce the tax that they are legally required to pay. It is, however, important to distinguish between the concepts of tax avoidance and tax evasion. The central issue, especially where the contract has no business purpose, is whether it is possible for the substance and legal form of the transaction to differ to such an extent that a court of law will favour the substance rather than the legal format. The debate is whether the courts should be encouraged to continue with their "judge-made" law or whether the tax jurisdictions should be supporting a legislative route as opposed to a judicial one, in their efforts not only to combat tax avoidance but also to preserve taxpayer certainty. The question is whether the Doctrine of "Substance over Form" as applied by the judiciary is effective in combating tax avoidance, or whether a legislated general anti-avoidance provision is required. An intensive literature survey examines the changes which have occurred in the application of judicial tests from the 1930's to date and investigates the different approaches tax jurisdictions follow in order to combat tax avoidance. The effect of the introduction of anti-avoidance provisions in combating tax avoidance is evaluated by making a comparison between the United Kingdom and South Africa. [n the United Kingdom, the courts are relied on to create anti-tax avoidance rules, one of which is the Doctrine of "Substance over Form". The doctrine is very broad and identifies various applications of the doctrine, which have been developed by the courts. In South Africa, the Doctrine of "Substance over Form" has been applied in certain tax cases; however the South African Income Tax Act does include anti-tax avoidance sections aimed at specific tax avoidance schemes, as well as a general anti-tax avoidance measure enacted as section 103. The judicial tests have progressed and changed over time and the introduction of anti-avoidance legislation in the Income Tax Act has had an effect on tax planning opportunities. A distinction needs to be made between fraudulent and bona fide transactions while recognising the taxpayer's right to arrange his or her affairs in a manner which is beneficial to him or her from a tax perspective. Judicial activism and judicial legislation in the United Kingdom has created much uncertainty amongst taxpayers and as a result strongly supports the retention of a general anti-avoidance section within an Income Tax Act. A general anti-avoidance provision, following a legislative route, appears to be more consistent and effective in combating tax avoidance.

Revenue collection agencies across the world aim to maximise revenue collection by minimising tax noncompliance. The different types of tax noncompliance are collectively referred to as the tax gap phenomenon, which revenue collection agencies address by means of various enforcement approaches and capabilities. Much like any organisation, the resources required to execute these capabilities are finite and require accurate organisational decision-making in order to make optimal use thereof. Information technology, and specifically decision support systems (DSS), is critical in enabling this decision-making process. Using the Structuration Model of Technology, the information needs, demand and offerings of revenue collection agencies are explored given their objective of narrowing the tax gap phenomenon using DSS. Emphasis is placed on the manner in which IT is used to address taxpayer noncompliance, the way in which IT supports knowledge creation and subsequently also facilitate the decision-making process of tax practitioners, and also the different types of IT offerings made available to decision-makers in the form of DSS. In doing so, this research presents the results of a case study on the South African Revenue Service in which a conceptual decision support system framework is developed aimed at minimising the tax gap phenomenon. The research is conducted as a qualitative single case study and presented through a narrative analysis. The framework is systematically constructed as the research findings emerge and concluded by means of a framework validation and transfer ability test. The research result is a conceptual DSS framework acting as a reference point to other revenue collection agencies with the objective of addressing taxpayer noncompliance through DSS. / Jurisprudence / D.

The cumulative system is still applied, but many scholars argue that this form of taxation is detrimental to society because it has \"cascade\" effect. When drafting the law that determines on the non-cumulative PIS / COFINS (Social Integration Program / Contribution to Social Security Financing), the legislature created the obligation linked to this form of calculation of Income Tax systematic. Thus, companies are taxed on taxable income required to calculate their social contributions to the non-cumulative basis, on the other hand, companies that are on presumed income will have cumulative PIS / COFINS rates. In addition, legislation has listed punctually what are the inputs and credits allowed to relieve the supply chain. These attitudes have caused a mismatch with the general objectives of the creation of non-cumulative, this because the set which credits are allowed to discount, no full applicability of the principle of non-cumulative. Plus, segregate the determination in cumulative and non-cumulative basis in the computation of income provides a number of non uniform taxpayers with distinct characteristics and especially with costs / expenses divergent. It is noteworthy that the borrowing under the heading input, the nomenclature used in the legislation, generates different interpretations by taxpayers causing the taxman questions on recognition of that cost. Given these facts, we attempted to study the impact that the non-cumulative because the results of companies segregating them for industrial, commercial and service delivery branch. As a result of the survey conducted, it was found that, for these companies in the industrial and commercial sectors, noncumulative reached their goals relieving the supply chain, but the understated way, because only deducts the credits listed in the law. As for the two analyzed service providers, who are bound to non-cumulative contributions of the non-cumulative only led to higher cumulative systematic payments. Through the analysis performed it is concluded that the first non-cumulative must be exercised in full and unrestricted manner, as it is the essence of the Principle of Non Cumulativity and more, the taxpayer must have the free decision choose to be cumulative or non-cumulative, thereby exerting an efficient and effective tax administration / A n??o cumulatividade surgiu com o objetivo de desonerar a cadeia produtiva. O sistema cumulativo ainda ?? aplicado, por??m muitos estudiosos afirmam que essa forma de tributa????o ?? prejudicial ?? sociedade, pois tem efeito cascata . Quando da elabora????o da lei que determina sobre a n??o cumulatividade do PIS/COFINS (Programa de Integra????o Social/ Contribui????o para Financiamento da Seguridade Social), o legislador criou a obrigatoriedade dessa sistem??tica atrelada ?? forma de apura????o do Imposto de Renda. Assim, empresas tributadas no Lucro Real est??o obrigadas a apurar suas contribui????es sociais na forma n??o cumulativa, por outro lado, empresas que est??o no Lucro Presumido ter??o as al??quotas cumulativas para o PIS/COFINS. Al??m disso, a legisla????o elencou pontualmente quais seriam os cr??ditos e insumos permitidos para desonerar a cadeia produtiva. Essas atitudes causaram um desencontro com os objetivos gerais da cria????o da n??o cumulatividade, isto porque, ao definir quais cr??ditos s??o permitidos para desconto, n??o h?? aplicabilidade plena do Princ??pio da N??o Cumulatividade. E mais, segregar a apura????o em cumulativo e n??o cumulativo com base na apura????o do lucro estipula um n??mero de contribuintes desuniformes, com caracter??sticas distintas e principalmente com custos/despesas divergentes. Ressalta-se ainda que a tomada de cr??dito sob a rubrica insumo, nomenclatura utilizada na legisla????o, gera diversas interpreta????es por parte dos contribuintes ocasionando questionamentos do Fisco sob o reconhecimento desse custo. Diante desses fatos, buscou-se estudar os impactos que a n??o cumulatividade causa nos resultados das empresas segregando-as por ramo industrial, comercial e de presta????o de servi??o. Como consequ??ncia do levantamento efetuado, identificou-se que, para estas empresas dos setores industriais e comerciais, a n??o cumulatividade atingiu seus objetivos desonerando a cadeia produtiva, por??m de forma suavizada, pois deduz apenas os cr??ditos elencados em lei. J?? para os dois prestadores de servi??o analisados, que s??o obrigados a n??o cumulatividade das contribui????es, a n??o cumulatividade s?? ocasionou pagamentos superiores ?? sistem??tica cumulativa. Atrav??s da an??lise efetuada conclui-se que primeiramente a n??o cumulatividade deve ser exercida de forma plena e irrestrita, tal qual ?? a ess??ncia do Princ??pio da N??o Cumulatividade e mais, o contribuinte deve ter a livre decis??o em optar por ser cumulativo ou n??o cumulativo, exercendo assim uma gest??o tribut??ria eficiente e efetiva
