The book describes the difficulties of the current international corporate income tax system. It starts by describing its origins and how changes, such as the development of multinational enterprises and digitalization have created fundamental problems, not foreseen at its inception. These include tax competition—as governments try to attract tax bases through low tax rates or incentives, and profit shifting, as companies avoid tax by reporting profits in jurisdictions with lower tax rates. The book then discusses solutions, including both evolutionary changes to the current system and fundamental reform options. It covers both reform efforts already under way, for example under the Inclusive Framework at the OECD, and potential radical reform ideas developed by academics.

This paper discusses the theory and practice of tax design to achieve an efficient and equitable outcome, i.e. in support of inclusive growth. It starts with a discussion of the key principles from tax theory to guide practical tax design. Then, it elaborates on more granular tax policy, discussing key choices in the structure of the personal income tax on labor and capital income, taxes on wealth, the corporate income tax, and consumption taxes. The paper concludes by highlighting the political economy considerations of the issues with concrete recommedtions as to how to implement tax reform.

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).

Discusses important tax policy issues facing developing countries today, provides a review of the role of tax incentives, and identifies some policy challenges posed by the globalization of the world economy. Draws on country cases.

Edited by Parthasarathi Shome, this Handbook was written primarily for economists who are responsible for analyzing and evaluating economic policies of developing countries at an applied level, and who would benefit from a comprehensive discussion of the concepts, principles, and prevailing issues of taxation.

There is a widespread concern that, in some parts of the world, governments are unable to exercise effective authority. When governments fail, more sinister forces thrive: warlords, arms smugglers, narcotics enterprises, kidnap gangs, terrorist networks, armed militias. Why do governments fail? This book explores an old idea that has returned to prominence: that authority, effectiveness, accountability and responsiveness is closely related to the ways in which governments are financed. It matters that governments tax their citizens rather than live from oil revenues and foreign aid, and it matters how they tax them. Taxation stimulates demands for representation, and an effective revenue authority is the central pillar of state capacity. Using case studies from Africa, Asia, Eastern Europe and Latin America, this book presents and evaluates these arguments, updates theories derived from European history in the light of conditions in contemporary poorer countries, and draws conclusions for policy-makers.

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.

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.
