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 additional tax ("penalties") imposable in terms of section 76(1) of the Income Tax Act (No 58 of 1962) when a taxpayer is in default, can be very harsh (up to 200% of the tax properly chargeable). The Commissioner may, in terms of section 76(2)(a), remit any penalty imposed, as he sees fit. However, when there was intent on the part of the taxpayer to evade the payment of tax, the Commissioner may not remit any portion of the 200% penalty imposable, unless he is of the opinion that "extenuating circumstances" exist. This dissertation examines the meaning of "extenuating circumstances", as interpreted by the judiciary, and lists the factors and defences that a taxpayer may plead to justify a remission of penalties, both in the case of an intention by the taxpayer to evade tax and in cases where the taxpayer is merely in default of section 76(1). / Accounting / MCOM (Accounting)

The research examined whether the services provided by the “sharing economy” platforms are adequately dealt with by the current South African tax systems. In addressing this main goal, the research analysed how the South African tax systems deal with the income and expenses of Uber, Airbnb and their respective service providers. The research also investigated how South Africa could classify “sharing economy” workers and how this would affect the deductibility of the worker’s expenses. A brief analysis was made of the taxation of the “sharing economy” businesses in Australia and the United States of America. These countries have implemented measures to effectively deal with regulating the “sharing economy” businesses. An interpretative research approach was used to provide clarity on the matter. Documentary data used for the research consists of tax legislation, case law, textbooks, commentaries, journal articles and theses. The research concluded that the current taxation systems have loopholes that are allowing participants in the “sharing economy” to avoid paying tax in South Africa. The thesis recommends that the legislature could adopt certain measures applied in Australia and the United States of America to more effectively regulate “sharing economy” in South African and remedy the leakages the current tax systems suffer, causing SARS to lose potential revenue.

Income tax in South Africa is levied in terms of the Income Tax Act, 58 of 1962 (the South African Income Tax Act) on taxable income, which by definition, is arrived at by deducting from ''gross income" receipts and accruals that are exempt from tax as well as deductions and allowances provided for in the Act. The South African Income Tax Act provides no guidance with regard to the taxation of income and expenditure from illegal activities. In this mini thesis, case law and legislation is reviewed in an attempt to provide clarity on the tax consequences of income and expenses arising from illegal activities. An overview is provided of the taxation of income and expenditure in respect of illegal activities in the United States of America, Australia and New Zealand. Similarities are found between the American, Australian, New Zealand and South African tax regimes in relation to the taxation of income earned from illegal activities, but there appears to be more certainty in America, Australia and New Zealand with regard to the deduction of expenses arising from illegal activities. In South Africa, taxpayers earning income from ongoing illegal activities will, in principle, comply with the definition of “trade” as defined in section 1 of the South African Income Tax Act. However, this is contrary to the view of the South African Revenue Service that illegal activities do not meet the definition of “trade”, a viewpoint that may not hold if challenged in court. Recommendations are made for the amendment of the South African Income Tax Act to specifically provide for the inclusion in “gross income” of income from illegal activities and to prohibit the deduction of expenditure arising from illegal activities.

The purpose of this study was to develop a conceptual framework to aid in the reduction of the taxation gap in South Africa (SA) through the use of third-party data and information technology. In order to develop a framework to prevent non-compliance, an understanding was required of the areas that would enable such a framework to be successful. Since governance, risk and compliance (GRC) is an emerging area in the corporate and information technology domain, organisations, including revenue bodies, are confronted with an increased risk and a growing number of regulatory, legal and other compliance requirements. The frame of reference for integrated governance, risk and compliance was used as base to determine the areas that had to be included in the new feasibility framework for the South African Revenue Service (SARS) in order for the framework to enhance compliance. Thus, the frame of reference for integrated governance, risk and compliance provided a contextual understanding of the areas that had to be reviewed in order to ensure that the framework that was developed adhered to all aspects that would make it a suitable and acceptable framework within SARS. Since the new conceptual framework will be used to address compliance and risk management, existing frameworks had to be considered – one in particular, namely the Compliance Risk Management Process as described by the Organisation for Economic Co-operation and Development (OECD). The OECD guidance note outlines compliance risk management as a structured iterative process for the “systematic identification, assessment, ranking, and treatment of tax compliance risks” that will enhance decision-making. This structural process is depicted in the Compliance Risk Management Process which can be used by revenue bodies, including SARS. Thus, once the different areas had been identified, discussed and understood, the existing Compliance Risk Management Process as described by the OECD was discussed to identify how the new conceptual framework that would be developed as part of this study could enhance this existing framework. Finally the framework was developed by making use of an extended literature review on the main characteristics of ‘big data’, which was then tested with the use of two selected case studies and concluded with a comparative analysis of the case studies. Overall, the framework will aid to determine whether it is feasible to continue with a project to use third-party data and information technology to automate the detection and prevention of taxation gaps before spending too many resources without any significant effect on diminishing the taxation gap. It is therefore recommended that SARS implement this new feasibility framework as a pre-check in order to determine whether:  there is third-party data available for a specific type of transaction that will result in the reduction of the taxation gap;  the third-party data is reliable and usable. If not, which changes are required from the third party in order to ensure that it can be linked to specific taxpayers (for example, such as capturing additional data or changing the format of existing data that had been captured in order to ease the extraction process);  any tax acts or legal aspects should be enhanced to ensure all relevant taxpayer information is available from a specific third party; and  both organisations (SARS and the third party) have the relevant information technology to ensure SARS can extract, store and manipulate the data in a timely fashion in order to obtain the maximum effect. In conclusion, a new feasibility framework was developed as part of this study in order to aid SARS with the reduction of the taxation gap by using third-party data and information technology. The purpose of the new feasibility framework is to identify whether there is third-party data available and whether any changes are required to the data in order to provide SARS with a mechanism to link it to specific taxpayers. This will provide SARS with guidance as to the steps that are required in order to automate the process of collecting third-party data through by using information technology. The feasibility framework would also indicate whether it is feasible to continue with such an automation project before exhausting too many resources without any significant effect on reducing the taxation gap. / Taxation / M.

This study investigated and examined the effectiveness and implementation of the existing internal controls designed specifically for exempted micro-enterprises (EMEs) contracting with the South African Social Security Agency (SASSA), in order to minimise the risk of possible tax evasion within the supply-chain management (SCM) processes. The research was completed by conducting a document review and face-to-face interviews with SASSA‟s SCM practitioners, risk manager, fraud and corruption manager, internal-control manager and internal auditor in order to identify risks of possible tax evasion within the SCM processes. It was concluded that there is a risk of possible tax evasion within the SCM processes due to the ineffectiveness and inconsistent implementation of internal controls designed for EMEs contracting with SASSA. This risk could be minimised by incorporating possible anti-tax-evasion procedures in the risk-assessment process, and ultimately in SASSA‟s broader fraud and corruption strategies. Such procedures should then help minimise funds being lost to the fiscus due to tax evasion in the SCM processes. / Taxation / M. Phil. (Accounting Sciences)

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.

This work entails a study of some of the schemes that are employed by country residents when companies and trusts are used as vehicles for investing in offshore tax-haven and low tax jurisdictions so as to avoid taxes. The study also entails a critical analysis of the effectiveness of the some of the laws in South Africa that curb such offshore tax avoidance schemes. Similar laws in the United Kingdom and in the United States are analysed in order to come up with some recommendations that could be considered for possible reform of the relevant South African laws where they are found wanting. Since offshore tax avoidance is an international issue, the effectiveness of the recommendations of some international organisations in preventing the depletion of countries' tax bases are also analysed. / JURISPRUDENCE / LLD
