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.

This study explores how the tax design called the X tax could alleviate the complexities and avoidance opportunities plaguing the existing U.S. system for taxing international business income.

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.

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.

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.

In a global economy where multinational enterprises (MNEs) play a prominent role, governments need to ensure that the taxable profits of MNEs are not artificially shifted out of their jurisdiction and that the tax base reported by MNEs in their country reflects the economic activity undertaken therein. For taxpayers, it is essential to limit the risks of economic double taxation.
