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.
