This technical note is the second of three addressing information technology (IT) themes and issues relevant to tax administrations. This note addresses how to select a suitable IT system for core tax administration functions. Note one covers the use of IT in tax administrations and how to develop an information technology strategic plan (ITSP). The third note focuses on implementation of a commercial-off-the-shelf (COTS) system. These technical notes are primarily for tax administrations that have no technology to manage their core tax processes, or their technology is limited and outdated. These notes focus on core tax functions and do not address other business systems (e.g., payroll, finance, document, and asset management systems).

New technologies are changing the way that tax administrations, taxpayers and their advisers interact, leading to a reduction in the compliance cost for taxpayers, a level playing field for large and small businesses, and fewer opportunities to engage in aggressive tax practices. Although entering a new world where processes are supported by machines inevitably disrupts traditional ways of working, the contributors to this indispensable book reveal the enormous potential of ‘tax technology’ to positively transform tax compliance, clearly showing both government and business how to manage the transition from the old to the new. With detailed treatment of the technology available in the tax field, the authors describe how to secure its benefits in such ways as the following: electronic balance sheets and invoices; automated transmission to tax authorities; innovative analytics applications; blockchain in tax law processes; process mining in VAT; real-time reporting with cryptography; and meeting the challenges to taxpayers’ rights to privacy and personal data protection. The contributions draw on an international conference held under the auspices of the Digital Economy Taxation Network at the Vienna University of Economics and Business in December 2020. The perspective throughout focuses on how to achieve better tax compliance at a lower cost. For this reason, this full-scale, practical guide on how to adapt tax law to new technologies and how to apply tax tech processes in practice will be welcomed by tax practitioners, tax administrations, and academics across the entire tax community.

This technical note is the first of three addressing information technology (IT) themes and issues relevant to tax administrations. This note focuses on the use of technology in tax administrations and how to develop an information technology strategic plan (ITSP). It is intended for tax administrations that are largely manual or have outdated legacy IT systems. The second note addresses how to select an IT system for core tax administrations functions. And the third note covers implementation of a commercial-off-the-shelf (COTS) system. These technical notes are primarily for use by tax administrations that have no technology to manage their core tax processes, or their technology is limited and outdated. These notes focus on core tax functions and do not address other business systems (e.g., payroll, finance, document, and asset management systems).

Selection of studies relating to taxation in developing countries. The papers are organized under the following subjects: approaches to development taxation, lessons from experience, taxation and incentives, problems in direct taxation, the reform of indirect taxation, the role of local taxes, tax administration and tax policy.

Building on previous FAD work in the tax administration field, this paper defines broad criteria for diagnosing the problems in a country’s tax administration and formulating an appropriate reform strategy. To be effective, this strategy should be based on the size of the tax gap and the country’s particular circumstances. This paper discusses some guiding principles which have provided the basis for successful reforms, including: reducing the tax system’s complexity, encouraging taxpayers’ voluntary compliance, differentiating the treatment of taxpayers by their revenue potential, and ensuring the reform’s effective management. Also discussed are specific bottlenecks that hinder the effectiveness of the tax administration’s operations.

Tax Administration 2015 is a comprehensive survey of tax administration systems, practices and performance across 56 advanced and emerging economies (including all OECD, EU, and G20 members).
