Expanding Taxable Capacity And Reaching Revenue Potential

An effective tax system is fundamental for successful country development. The first step to understand public revenue systems is to establish some commonly agreed performance measurements and benchmarks. This paper employs a cross-country study to estimate tax capacity from a sample of 104 countries during 1994-2003. The estimation results are then used as benchmarks to compare taxable capacity and tax effort in different countries. Taxable capacity refers to the predicted tax-gross domestic product ratio that can be estimated with the regression, taking into account a country's specific economic, demographic, and institutional features. Tax effort is defined as an index of the ratio between the share of the actual tax collection in gross domestic product and the predicted taxable capacity. The authors classify countries into four distinct groups by their level of actual tax collection and attained tax effort. This classification is based on the benchmark of the global average of tax collection and a tax effort index of 1 (when tax collection is exactly the same as the estimated taxable capacity). The analysis provides guidance for countries with various levels of tax collection and tax effort.

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.

In 1997, Uganda undertook extensive reforms in tax legislation. This had been preceded by the structural reforms in tax administration that saw the creation of the Uganda Revenue Authority in 1991. The aim of the far reaching reforms was to improve the tax system and increase its revenue productivity. This book demonstrates that the reforms were not as successful as anticipated and revenues have not improved in a sustained way. The revenue from direct taxes only contributes about 20% to the total revenue, well below the Sub-Saharan average of 40%. This has focused attention on the appropriateness of the reforms. The focus of the reforms on achieving efficiency did not sufficiently take into account the fundamental importance of equity within the system. As a result, the Income Tax Act 1997 embodies distortions and inequalities in the treatment of taxable income and taxpayers that have led to inefficiency in the system as a whole. The tax reforms also took a narrow technical view of the tax system. The book employs political economy and optimal theory to explain the weaknesses in the tax system. It is argued that the reforms, although well designed, were not likely to be successful given the timing and context of implementation. The multidisciplinary and functionalist approach of the book is helpful in highlighting the constraints in which tax design and tax reform is undertaken in Uganda. It is argued that the reforms we “blunted” by the manner of their formulation and context of implementation. Taxation is a socio-political issue and yet the IMF and World Bank which supported the reforms did not take into account the limited political will. The lack of consensus in policy formulation has weakened the socio-contract and allowed the government to blame external factors for the poor performance. The weaknesses in governance and corruption have had an impact on the tax system by encouraging tax avoidance and evasion among political elites as well as on activities in the informal sector.

Domestic revenue mobilization has been a longstanding challenge for countries in the Middle East and Central Asia. Insufficient revenue has often constrained priority social and infrastructure spending, reducing countries’ ability to reach the Sustainable Development Goals, improve growth prospects, and address climate related challenges. Moreover, revenue shortfalls have often been compensated by large and sustained debt accumulation, raising vulnerabilities in some countries, and limiting fiscal space to address future shocks. The COVID-19 pandemic and the war in Ukraine have compounded challenges to sustainable public finances, underscoring the need for revenue mobilization efforts. The recent global crises have also exacerbated existing societal inequalities and highlighted the importance of raising revenues in an efficient and equitable manner. This paper examines the scope for additional tax revenue mobilization and discusses policies to gradually raise tax revenue while supporting resilient growth and inclusion in the Middle East and Central Asia. The paper’s main findings are that excluding hydrocarbon revenues, the region’s average tax intake lags those of other regions; the region’s fragile and conflict-affected states (FCS) face particular challenges in mobilizing tax revenue; In general, there is considerable scope to raise additional tax revenue; countries have made efforts to raise tax collection, but challenges remain; tax policy design, notably low tax rates and pervasive tax exemptions, is an important factor driving tax revenue shortfalls; weak tax compliance, reflecting both structural features and challenges in revenue administration, also plays a role; and personal income tax systems in the region vary in their progressivity—the extent to which the average tax rate increases with income—and in their ability to redistribute income. These findings provide insights for policy action to raise revenue while supporting resilient growth and inclusion. The paper’s analysis points to these priorities for the region to improve both efficiency and equity of tax systems: improving tax policy design to broaden the tax base and increase progressivity and redistributive capacity; strengthening revenue administration to improve compliance; and implementing structural reforms to incentivize tax compliance, formalization, and economic diversification.

This book includes papers presented at the 14th International Conference “Economies of the Balkan and Eastern European Countries” (EBEEC), held in Florence, Italy, in May 2022. It sheds new light on the micro- and macroeconomic developments in the Eastern European and Balkan countries, taking into account also the broader regional and global factors influencing these developments. In particular, it includes the latest theoretical and empirical research and policy insights from Central and Southeastern Europe and presents new ideas on how to resolve economic problems, also generated by the pandemic, in the Balkan and Eastern European economies in a pan-European context. By examining how the decisions and the performance of economic, social, and political actors in the area are intertwined with wider events, also at a global level, the papers highlight the dynamic development in Eastern Europe and the Balkans region. Further, the book demonstrates how the area is evolving within the framework of European economic integration and the global effervescent economy.

Taxation and Development highlights the importance of better understanding the ways in which taxes and expenditure are linked. Focusing on developing countries, the book argues for a broader approach to the topic, with a secondary focus on developing a
