The excessive complexity and burden of the Brazilian tax system, riddled by cumulative indirect taxes and heavy payroll contributions, have led to an accumulation of fiscal incentives aimed at reducing its burden on taxpayers and productive activities. Federal and subnational tax expenditures currently stand at over 5 percent of GDP. Rationalizing them can only be comprehensively feasible in the context of a broader sequenced tax reform, and could reduce resource misallocation and income inequality, as well as provide new revenues.

“The most important book on government policy that I’ve read in a long time.” —David Leonhardt, New York Times Even as they have become fabulously wealthy, the ultra-rich have seen their taxes collapse to levels last seen in the 1920s. Meanwhile, working-class Americans have been asked to pay more. The Triumph of Injustice presents a forensic investigation into this dramatic transformation, written by two economists who have revolutionized the study of inequality. Blending history and cutting-edge economic analysis, Emmanuel Saez and Gabriel Zucman offer a comprehensive view of America’s tax system alongside a visionary, democratic, and practical reinvention of taxes.

There is a growing debate on the relative merits of universal and targeted social assistance transfers in achieving income redistribution objectives. While the benefits of targeting are clear, i.e., a larger poverty impact for a given transfer budget or lower fiscal cost for a given poverty impact, in practice targeting also comes with various costs, including incentive, administrative, social and political costs. The appropriate balance between targeted and universal transfers will therefore depend on how countries decide to trade-off these costs and benefits as well as on the potential for redistribution through taxes. This paper discusses the trade-offs that arise in different country contexts and the potential for strengthening fiscal redistribution in advanced and developing countries, including through expanding transfer coverage and progressive tax financing.

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.

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.
