How can Low-Income Countries (LICs) enhance tax revenue collection to finance their vast development needs? We address this question by analyzing seven tax reform experiences in LICs (Burkina Faso, The Gambia, Maldives, Mauritania, Rwanda, Senegal, and Uganda). Three lessons stand out, although reforms must be tailored to individual circumstances: (i) Tax reforms require first and foremost political commitment and buy-in from key stakeholders; (ii) Countries that pursue both revenue administration and tax policy reforms tend to see much larger and persistent gains; and (iii) A successful strategy often starts with fiscal reform measures with immediate effect to build momentum. These can include: simplifying the tax system; curbing exemptions; reforming indirect taxes on goods and services (e.g., excises); and better managing compliance risks through strengthening taxpayer segmentation (often beginning with strengthening the Large Taxpayers Office). A comprehensive reform strategy (e.g., a medium-term revenue strategy) can help to properly sequence reform measures and facilitate their implementation.

Taxes are a crucial policy issue, especially in developing countries. Just recently, proposals to raise middle-class taxes toppled the Bolivian government, and plans to extend or increase the value-added tax caused political unrest in Ecuador and Mexico. Despite the impact of tax policy on developing countries, a comprehensive study has yet to be written. Treating Argentina, Brazil, India, Kenya, Korea, and Russia as key case studies, this volume outlines the major aspects of current tax codes and explores their economic and political implications. Examples of both the poorest and wealthiest developing countries, Argentina, Brazil, India, Kenya, Korea, and Russia uniquely demonstrate the diverse fiscal problems of tax reform. Each economy relies heavily on indirect and corporate income taxes, though recently some have reduced their tariff rates and have switched from excise to value-added taxes. There is a large, informal economy in most of these countries, and tax evasion by firms is a significant concern. As a result, tax revenue remains low, even though rates are as high as those in developed economies. Also, unconventional methods to collect revenue have been implemented, including bank debit taxes, state ownership of firms, and implicit taxes on individuals in the informal sector. Exploring these and other concerns, as well as changes in tax law, administration, and fiscal pressures, this comprehensive anthology clarifies the current landscape of tax administration and the economic future of the world's poorer economies.

How do countries mobilize large tax revenue—defined as an average increase in the tax-to-GDP ratio of 0.5 percent per year over three years or more? To answer this question, we build a novel dataset covering 55 episodes of large tax revenue mobilization in low-income countries and emerging markets. We find that: (i) reforms of indirect taxes and exemptions are the most common tax policy measures; (ii) multi-pronged tax administration reforms often go hand in hand with tax policy measures or are stand alone; and (iii) sustainability of the episodes hinges on tax administration reforms in the key compliance areas (risk-based audits, registration, filing, payment, and reporting).

The Fund has long played a lead role in supporting developing countries’ efforts to improve their revenue mobilization. This paper draws on that experience to review issues and good practice, and to assess prospects in this key area.

A review of current thinking on taxation which examines the changes in tax structure occurring in 11 countries, ranging from Indonesia and Mexico to Sweden and the United States. The book coincides with a trend towards tax reform which has taken hold in many developed and developing countries.

This paper addresses core challenges that all tax administrations face in dealing with noncompliance—which are now receiving renewed attention. Long a priority in developing countries, assuring strong compliance has acquired greater priority in countries facing intensified revenue needs, and is critical for fairness and statebuilding.
