Investment in strengthening public institutions has been identified as necessary for effective policy implementation and public service delivery. Lately, key inter-governmental institutions including the OECD, UN and World Bank have identified tax administration (SDG17-Target-17.1) as one particular public institution that must be strengthened to mobilize the additional revenue required for implementing the Sustainable Development Goals (SDGs), in an efficient, accountable manner (SDG16-Target-16.6). There is increasing anecdotal evidence that some of the digital technologies can significantly support the transformations required in public institutions to tackle societal challenges like those associated with the SDGs. However, systematic studies on how digital technologies have been harnessed to address specific societal challenges or employed in specific public institutions to achieve significant changes remain sparse. Recently, tax administrations in OECD countries, led by the Irish Revenue, highlighted their experiences on the adoption of advanced data analytics technologies across different functions in their respective institutions. These tax institutions and others with experience of digital technologies deployment present a rare opportunity for detailed investigation of challenges, strategies, mechanisms and accrued benefits of the use of these technologies. This project aims to carry out a rigorous study of how the contextual, organisational, technological and human factors interact in the adoption of data analytics and digital technologies in tax administrations. Through in-depth interdisciplinary case studies of selected tax authorities that have adopted and used data analytics and other digital technologies, we will: 1) develop a refined understanding and model of successful digital technology adoption in public institutions, 2) translate findings into guidelines for decision-makers on how to effectively deploy digital technologies, in a transparent and accountable manner; and 3) Identify necessary technical updates to standards related to the deployment of the respective digital technologies in public institutions. Our findings are expected to impact the capacity of tax administrations to effectively support the implementation of SDGs.
