Tax reform in Latin America during the 1980s emphasized broad-based, low-rate consumption taxes over steeply progressive income and property taxes, primarily to simplify the tax structure and facilitate tax administration. While tax reform need not necessarily raise tax-to-GDP ratios, countries that undertook tax reform experienced a higher revenue gain in terms of GDP relative to those that did not. Tax reform issues during the 1990s will include a minimum income tax, alternative corporate taxes (cash flow tax, assets tax), capturing difficult tax bases (financial intermediation, property), environment taxes, extending withholding as a taxing mechanism, and tax harmonization.

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 book was written in the context of new and innovative policies for customs and tax administration reform. Eight chapters describe how measurement and various quantification techniques may be used to fight against corruption, improve cross-border celerity, boost revenue collection, and optimize the use of public resources. More than presenting “best practices” and due to the association of academics and practitioners, the case studies explore the conditions under which measurement has been introduced and the effects on the administrative structure, and its relations with the political authority and the users. By analyzing the introduction of measurement to counter corruption and improve revenue collection in Cameroon, two chapters describe to which extent the professional culture has changed and what effects have been noted or not on the public accountability of fiscal administrations. Two other chapters present experiments of uses of quantification to develop risk analysis in Cameroon and Senegal. By using mirror analysis on the one hand and data mining on the other hand, these two examples highlight the importance of automated customs clearance systems which collect daily extensive data on users, commodities flows and officials. One chapter develops the idea of measuring smuggling to improve the use of human and material resources in Algeria and nurture the questioning on the adaptation of a legal framework to the social context of populations living near borders. Finally, two examples of measurement policies, in France and in South Korea, enlighten the diversity of measurement, the specificities of developing countries and the convergences between developing and developed countries on common stakes such as trade facilitation and better use of public funds.

Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

Excise taxes on tobacco and alcohol products can be an effective instrument for promoting public health through the curbing of smoking and excessive drinking, while raising significant financing for development priorities. Designed and implement well, excise taxes represent a win-win for public health and finances. While the public policy rationale for excise reforms is strong in both developed and developing countries, realizing reforms in practice often faces significant opposition by the industry and vested interests. Low level, complex and poorly designed excise tax regimes persist. Getting the technical details right, and effectively managing the political economy of reforms, are vital to securing better excise tax outcomes. The Philippines passed in 2012, implemented, and has been results monitoring a successful tobacco and alcohol tax, dubbed Sin Tax. The reform not only greatly increased, simplified and improved the excise tax reform, but also earmarked the significant part of the large ensuring incremental revenues to helping finance Universal Health Care (UHC) for the bottom forty percent of the population. Sin Tax Reform in the Philippines summarizes both the technical and political economy aspects of tobacco and excise tax reforms. The study analyzes issues of rate structure and levels, implementation phasing, and equity impact analysis. The book is intended as a resource for audiences in both the Philippines and other countries wishing to promote successful excise tax reforms to towards between public sector governance, finances and health. For the Philippines, it highlights measures to ensure that the revenue and expenditure measures associated with the reform continue to be delivered, and can be deepened over time. The Philippines experience should prove encouraging and useful for reform champions in other countries advancing similar types of excise tax and development financing/expenditure earmarking for equitable development and public health.

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.
