Tax revenue forms the backbone of any economy. The quality of the e-services provided by a revenue authority is therefore crucial, as e-service quality directly influences the burden of complying with tax obligations, and hence affects the tax compliance climate in a country. The aim of the study is the development of a measuring instrument that encapsulates the ‘lens of a tax practitioner’ in an e-service revenue authority setting. In order to develop a conceptual framework, an in-depth, qualitative approach was used to identify a comprehensive range of service attributes and dimensions that potentially drive e-service quality in the revenue authority setting. This framework is then compared with other relevant service quality models to derive at a proposed e-service quality-measuring instrument. Findings from this study may advance the understanding and the management of the e-service quality of the e-services in a revenue authority setting.
