This paper analyses presumptive taxation methods and their application in Sub-Saharan Africa. Presumptive taxation involves simple techniques to capture domestic transactions and sources of income that frequently escapes conventional taxation.

Trade is an essential driver for sustained economic growth, and growth is necessary for poverty reduction. In Sub-Saharan Africa, where three-fourths of the poor live in rural areas, spurring growth and generating income and employment opportunities is critical for poverty reduction strategies. Seventy percent of the population lives in rural areas, where livelihoods are largely dependent on the production and export of raw agricultural commodities such as coffee, cocoa, and cotton, whose prices in real terms have been steadily declining over the past decades. The deterioration in the terms of trade resulted for Africa in a steady contraction of its share in global trade over the past 50 years. Diversification of agriculture into higher-value, non-traditional exports is seen today as a priority for most of these countries. Some African countries-in particular, Kenya, South Africa, Uganda, CÔte d'Ivoire, Senegal, and Zimbabwe-have managed to diversify their agricultural sector into non-traditional, high-value-added products such as cut flowers and plants, fresh and processed fruits and vegetables. To learn from these experiences and better assist other African countries in designing and implementing effective agricultural growth and diversification strategies, the World Bank has launched a comprehensive set of studies under the broad theme of "Agricultural Trade Facilitation and Non-Traditional Agricultural Export Development in Sub-Saharan Africa." This study provides an in-depth analysis of the current structure and dynamics of the European import market for flowers and fresh horticulture products. It aims to help client countries, industry stakeholders, and development partners to get a better understanding of these markets, and to assess the prospects and opportunities they offer for Sub-Saharan African exporters.

This book captures the critical role of taxation in shaping government responsiveness and accountability in developing countries.

Turnover (sales) is frequently used in developing countries as a presumptive income tax base, to economize on the costs of tax administration and taxpayer compliance. We construct a simple model where a size threshold separates firms paying turnover tax from those paying profit tax (regular income tax), and where firms have the option of producing in the untaxed, informal sector. The optimal turnover tax rate trades off two policy concerns: reducing informality and avoiding strategic reductions in sales by firms seeking to remain below the threshold for the profit tax. We provide analytical results and calibrate the model to compute the optimal policy using realistic parameter values. The optimal turnover tax rate for countries with large informal sectors is found to be around 2.5% across most scenarios, while the threshold separating the turnover tax regime from profit tax lies for the most part between $65,000 and $95,000. Introducing an optimally designed turnover tax reduces the rate of informality of businesses by about 12 percentage points in the calibrated model.

Revenue Administration Handbook provides a comprehensive overview of the structure and management of tax and customs administrations, covering topics such as tax policy design considerations that impact tax administration, institutional setup and strategic planning, analyticalcapacities and maturity models, core business processes, and tax sanctions. It also presents pioneering work in the field of digital transformation and how to build data science capabilities, including a roadmap for policy makers and tax officials on how to incorporate and manage disruptive technologies, such as machine learning, into building modern revenue administrations while taking into account their respective maturity levels. This practical manual provides examples from real-life World Bank projects so that policy makers, tax officials, information technology experts, and information and communication technology providers can better understand the needs of revenue administrations to design and implement the most appropriate technology solutions. This reference work is intended to serve as a tool to facilitate the progress and modernization of tax and customs administrations worldwide, and to reach not only tax experts and policy makers, but also other government officials, businesses and academic communities, as well as the larger public, since all are relevant stakeholders with an active role in day-to-day revenue administration operations. ------------------------- “This is a very timely and useful reference for tax practitioners and stakeholders, coming at a time when tax administrators continue to grapple with the challenge of how to accelerate the modernization of technology systems to remain effective in a rapidly advancing and technologydriven business environment.†? MOSES WASIKE, Senior financial management specialist, World Bank “This is an impressive piece of work that pulls together many different strains on tax administration.†? JEFFREY OWENS, Director, Global Tax Policy Center, Vienna University “Applying several technologies discussed in this handbook in an innovative manner will definitely help leapfrog countries to pursue a digital transformation agenda, especially in the areas of efficiency, productivity, and citizen satisfaction.†?
