This study examines the factors to consider in establishing an effective tax Ombudsman in South Africa. It seeks to establish how the democratic protection institutions such as the South African Public Protector and the South African Human Rights Commission and the Courts created in terms of the 1996 Constitution vis-à-vis the ways the South African Revenue Service‟ (hereinafter referred to as SARS) new court rules and Service Monitoring Offices safeguard and protect taxpayers rights against SARS‟ administrative abuses. The researcher reviews and analyses literature gathered from the following sources: the Australian and Canadian tax Ombudsman, the United Kingdom‟s tax adjudicator, the South African motor industry Ombudsman, the South African banking services Ombudsman, the South African Public Protector, the Tax Administration Act (28 of 2011) (hereinafter referred to as the TAA), the South African Constitution (108 of 1996), and other popular scientific articles and reports on the introduction of the tax Ombudsman in South Africa. The findings reveal the core factors that underscore the establishment of an effective tax Ombud in South Africa to include: independence, neutrality, credible review process and confidentiality. Other auxiliary factors with regard to the appointment of the tax Ombud are: leadership skills, honesty, integrity and courage. Furthermore, the provisions of the TAA, in relation to the appointment of the tax Ombud‟s funding, staffing, location, and powers with particular reference to cost recovery and disclosure of taxpayers‟ confidential information, impede on the tax Ombud‟s independence. It also emerged from this study that the independence of the tax Ombud‟s office is being over-emphasised, leaving other pertinent issues of equal importance, such as education and publicity, unattended to. The recommendations for this study revolve on the tax Ombud‟s appointment, budget and recruitment of its own staff, building a reputation of independence through public education and the power to recover costs. / MCom (South African and International Taxation), North-West University, Potchefstroom Campus, 2014

Prior to 1994, South African taxpayers had little protection from fiscal legislation or the decisions, actions or conduct of the South African Revenue Service (“SARS”) that violated their common law rights. Parliament reigned supreme and in tax matters, the strict and literal approach to the interpretation of statutes was employed, with the judiciary often quoting the mantra that there is “no equity about tax”. The Income Tax Act (Act No 58 of 1962) was littered with discriminatory and unfair provisions based on age, religion, sex and marital status. Even unreasonable decisions taken by SARS could not be reviewed by the judiciary as “unreasonableness” was not a ground for review of the exercise of a discretion by SARS. On 27 April 1994, the constitutional order changed. Parliamentary supremacy was replaced with constitutional supremacy and the rights to privacy, equality, human dignity, property and just administrative action were codified in a Bill of Rights. The codification of these fundamental rights has materially changed the nature and extent of the rights of South African taxpayers. The objective of this thesis, therefore, is to identify, analyse and discuss South African taxpayers’ rights from a constitutional perspective. The following major conclusions can be drawn from the research done: - the judiciary have been forced to reappraise their approach to the interpretation of statutes from a “strict and literal” to a “purposive” approach that is in accordance with the values underpinning the new constitutional order; - new legislation has amended some of the so-called “reverse” onus of proof provisions that were constitutionally unsound – this should result in greater fairness and consistency for affected taxpayers especially in the area of when penalties may be imposed; - the concept of clean hands and good facts can influence the judiciary when arguing that a taxpayer’s right to just administrative action has been violated; and - discriminatory and unfair legislation and conduct on the part of SARS may and should be attacked on a substantive law basis, especially where human dignity is at stake. The overall conclusion is that taxpayers’ rights are more far-reaching than prior to 1994 but still have some way to go before they are fully interpreted and developed. / Accounting Science / D.Compt.

South Africa has already implemented three tax–amnesty programmes: the Second Small Business Tax Amnesty 10 of 2006, the Exchange Control Amnesty Act 12 of 2003 and the Tax Amnesty Act 19 of 1995. In the 2010 budget announcement the Minister of Finance, Mr. Pravin Gordan, announced that there will be another chance for taxpayers to get their tax affairs in order with the Voluntary Disclosure Programme. The main goal of this study is to determine whether the Voluntary Disclosure Programme will prove to be effective or not. The research method utilised is based on an advanced literature study. The secondary goals are as follows: * to obtain a thorough knowledge regarding the three previous tax–amnesties that was implemented in South Africa. A prediction as to the success of the Voluntary Disclosure Programme can be made when using the total number of applications received and the amount of revenue that was received by the previous amnesties, as a measure of success; * to obtain a thorough knowledge of other countries' amnesty–programs, including the following: Australia, Ireland, Canada and the United Kingdom. Their experience and successes regarding their amnesty–programs will be used to predict the success of the Voluntary Disclosure Programme; an * to determine whether the Voluntary Disclosure Programme can be declared as fair. This study indicated that the Voluntary Disclosure Programme may not be effective and that it may have a negative impact on the tax compliance of taxpayers. A recommendation from this study is that the government should win the trust of taxpayers, which will lead to an automatic improvement in tax compliance. This study indicated that the tax amnesty programs should not be used as a mechanism to enhance tax compliance. An issue that needs further exploration is the impact that the Voluntary Disclosure Programme will have in the long–term on tax compliance in South Africa. / Thesis (M.Com.

Abstracts in English, Afrikaans and Northern Sotho / The tax compliance costs of individual taxpayers in South Africa are unknown, and it is essential to determine, amongst other things, whether these costs pose a risk of causing non-compliance, which could have a negative effect on the collection of tax revenue. Hence, the aim of the study was to assess the tax compliance costs of individual taxpayers in South Africa. The assessment of tax compliance costs entailed calculating these costs in relation to the submission of income tax returns and post-filing activities, ascertaining the determinants of these costs and suggesting ways to reduce them. Using data collected from an online survey conducted among 10 260 taxpayers, it was estimated (applying various methods) that income tax compliance costs of individual taxpayers for the 2018 year of assessment were between 3.61% and 5.31% of the personal income tax revenue. These results compared well with ratios reported in most studies conducted in other countries and showed a reduction from the results obtained from 752 taxpayers for the 2017 year of assessment. Chi-square automatic interaction detection (CHAID), a decision tree modelling technique, was used to ascertain the determinants of tax compliance costs and to identify specific groups of taxpayers associated with distinct ranges of the determinants that were statistically significant predictors of tax compliance costs. This breakdown enabled a better understanding of the influence that the specific values of the continuous determinants, such as the service quality rating of the South African Revenue Service (SARS), and the categorical determinants, such as education level and employment status, have on tax compliance costs. The CHAID analysis therefore provided an additional level of insight not possible with regression analysis, enhancing the usability of the results. Employment status and income tax bracket had the strongest association with tax compliance costs (on average, self-employed taxpayers and taxpayers in the highest income tax bracket had the highest total tax compliance costs). Various other determinants, for example, type of assistance obtained, gender, education level, complexity of tax legislation, complexity of SARS guides, and SARS’s service quality rating were also identified in the analyses. / Die belastingvoldoeningskoste van individuele belastingpligtiges in Suid-Afrika is onbekend, en dit is noodsaaklik om, onder andere, te bepaal of hierdie koste ʼn risiko van nievoldoening inhou wat ʼn negatiewe uitwerking op die insameling van belastinginkomste kan hê. Die doelwit van die studie was dus om die belastingvoldoeningskoste van individuele belastingpligtiges in Suid-Afrika te assesseer. Die assessering van belastingvoldoeningskoste behels die berekening van hierdie koste ten opsigte van die indiening van inkomstebelastingopgawes en ná-indieningsaktiwiteite, bepaling van die determinante van hierdie koste en voorstelle van hoe om dit te verminder. Aan die hand van data wat ingesamel is deur ʼn aanlyn opname onder 10 260 belastingpligtiges, is (deur middel van verskeie metodes) geraam dat inkomstebelasting-voldoeningskoste van individuele belastingpligtiges vir die 2018-assesseringsjaar tussen 3.61% en 5.31% van die persoonlike-inkomstebelastinginkomste was. Hierdie resultate het goed vergelyk met verhoudings soos berig in die meeste studies wat in ander lande uitgevoer is en het ʼn afname gewys in die resultate wat by 752 belastingpligtiges vir die 2017-assesseringsjaar bekom is. Chi-kwadraat outomatiese wisselwerkingbespeuring (chi-square automatic interaction detection – CHAID), ʼn besluitnemingskema-modelleringtegniek, is gebruik om die determinante van belastingvoldoeningskoste te bepaal en om spesifieke groepe belastingpligtiges te identifiseer wat statisties-beduidende voorspellers van belastingvoldoeningskoste is. Hierdie uiteensetting het ʼn beter begrip daargestel van die invloed wat die spesifieke waardes op die deurlopende determinante, soos die diensgehaltegradering van die Suid-Afrikaanse Inkomstediens (SARS), en die kategoriedeterminante, soos onderwysvlak en indiensnemingstatus, op belastingvoldoeningskoste het. Die CHAID-ontleding het dus ʼn bykomende vlak van insig voorsien wat nie moontlik is met regressieontleding nie en sodoende die bruikbaarheid van die resultate verbeter. Indiensnemingstatus en inkomstebelastingkategorie het die sterkste assosiasie met belastingvoldoeningskoste (belastingpligtiges in eie diens en belastingpligtiges in die hoogste inkomstekategorie het gemiddeld die hoogste totale belastingvoldoeningskoste). Verskeie ander determinante, byvoorbeeld, soort bystand verkry, geslag, onderwysvlak, kompleksiteit van belastingwetgewing, kompleksiteit van SARS-gidse en SARS-diensgehaltegradering is ook in die ontledings geïdentifiseer. Die studie het afgesluit met voorstelle om individuele belastingspligtiges se belastingvoldoeningskoste te verlaag. / Ditshenyegelo tša ditefelo tša go obamela melawana ya metšhelo ka balefamotšhelo ka Afrika Borwa ga di tsebje, gomme go bohlokwa gore re tsebe, gareng ga tše dingwe, ge eba ditshenyegelo tše di tliša kotsi ya go baka gore balefamotšhelo ba se ke ba obamela melawana ya metšhelo, e lego seo se ka bago le seabe sa go se loke go kgoboketšo ya letseno la motšhelo.
