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 Reform in Developing Countries carefully examines the experience of eight developing countries that have undergone -- and in some instances are still undergoing -- significant and comprehensive tax reform. The countries are Bolivia, Colombia, Indonesia, Jamaica, Korea, Mexico, Morocco, and Turkey. It draws on their experiences to find lessons learned and to see how they may be applied to other countries on the road to tax reform. Equal attention is given to the process of tax reform, how it is implemented, and the substance or results of reform efforts. Throughout, the focus is on the practical rather than the theoretical aspects of tax reform.

This is a collection of papers that study the constraints on fiscal systems, imposed by problems of institutions, administration, and incentives in developing, and post-Socialist economies. Chapter two focuses on the administration of indirect taxation, and provides a case study of indirect taxation in Tanzania. This shows how evasion can be documented, and quantified, through a case study that looks at a particular type of reform, aimed at curbing evasion: franchising, or privatizing the right to tax, which has been tried in several Tanzanian towns as a way of collecting vendor fees, for access to a public market. Chapter three is a theoretical study of evasion under a value-added tax (VAT), and the inefficiencies it can create. Chapter four studies the fiscal constraints within the federal politics of Russia, while Chapters five and six examine case studies (India) in fiscal federalism, in which the determination of fiscal outcomes is - to a considerable degree - a matter of bargaining between political entities in the center, and in the periphery. In both cases, it appears that large-scale distortions, away from an ideal tax system, emerge as a result, suggesting corruption can be fought by increasing functional specialization within a tax bureaucracy. The last chapter looks at the problem of opportunistic taxation, particularly regarding the African context, and studies various ways in which the problem can be alleviated.

Electricity, natural gas, telecommunications, railways, and water supply, are often vertically and horizontally integrated state monopolies. This results in weak services, especially in developing and transition economies, and for poor people. Common problems include low productivity, high costs, bad quality, insufficient revenue, and investment shortfalls. Many countries over the past two decades have restructured, privatized and regulated their infrastructure. This report identifies the challenges involved in this massive policy redirection. It also assesses the outcomes of these changes, as well as their distributional consequences for poor households and other disadvantaged groups. It recommends directions for future reforms and research to improve infrastructure performance, identifying pricing policies that strike a balance between economic efficiency and social equity, suggesting rules governing access to bottleneck infrastructure facilities, and proposing ways to increase poor people's access to these crucial services.

Tax administration improvements have contributed significantly to a doubling of China’s tax-to-GDP ratio and the substantial reduction in taxpayers’ compliance costs since the mid-1990s. This paper describes the key features of China’s tax administration and their evolution over the last 20 years. It also identifes emerging challenges to the tax system and areas where further tax administration improvements are needed to sustain tax revenue and reduce taxpayers’ compliance costs in the future.

The purpose of this note is to provide a framework for improving tax policy design in fragile and conflict-affected states, which face political and institutional constraints. This note begins with an overview of experiences in revenue mobilization in fragile states, including relative to other country groups—in particular, nonfragile states and formerly fragile states; that is, countries that exited fragility during the period under study. A discussion follows of how the principles of tax policy design should be applied in fragile states, particularly the relative importance of the revenue objective vis-à-vis other objectives, such as equity and efficiency. The two sections that follow provide guidance on tax policy design in the emergency and consolidation phases, respectively, and discuss how governments can use tax policy to transition from one phase to another, eventually overcoming fragility. The note concludes with key lessons and a set of guiding principles for tax reform in fragile states.
