How To Establish A Tax Policy Unit

How to Establish a Tax Policy Unit

Risks to macroeconomic stability posed by excessive private leverage are significantly amplified by tax distortions. ‘Debt bias’ (tax provisions favoring finance by debt rather than equity) has increased leverage in both the household and corporate sectors, and is now widely recognized as a significant macroeconomic concern. This paper presents new evidence of the extent of debt bias, including estimates for banks and non-bank financial institutions both before and after the global financial crisis. It presents policy options to alleviate debt bias, and assesses their effectiveness. The paper finds that thin capitalization rules restricting interest deductibility have only partially been able to address debt bias, but that an allowance for corporate equity has generally proved effective. The paper concludes that debt bias should feature prominently in countries’ tax reform plans in the coming years.

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.

Building on previous FAD work in the tax administration field, this paper defines broad criteria for diagnosing the problems in a country’s tax administration and formulating an appropriate reform strategy. To be effective, this strategy should be based on the size of the tax gap and the country’s particular circumstances. This paper discusses some guiding principles which have provided the basis for successful reforms, including: reducing the tax system’s complexity, encouraging taxpayers’ voluntary compliance, differentiating the treatment of taxpayers by their revenue potential, and ensuring the reform’s effective management. Also discussed are specific bottlenecks that hinder the effectiveness of the tax administration’s operations.

This note aims to inform governments on how to account for tax expenditures and use that information in fiscal management. The emphasis is on developing and emerging market economies, where the use of such accounts is in its infancy because of data constraints, insufficient human and financial resources, and weak fiscal institutions. Most developing economies, more-over, do not have tax policy units in their Ministry of Finance to provide analytical support to the govern¬ment and legislature that integrates all revenue policy aspects. As a result, the tax policy framework can be fragmented: line ministries compete in the provision of sectoral tax incentives, but do not report on their cost. The note is organized as follows. The second section outlines the role that tax expenditure measurement and reporting can play in fiscal management. The third section provides a step-by-step approach on how tax expenditure accounts can be built, with emphasis on data, methods and models, and institutional requirements. The section is concerned primarily with the direct cost of tax expenditures—that is, the revenue forgone because of them. It does not deal with their indirect costs, which could include economic efficiency losses and additional tax administration resources, and it does not address assessment of the benefits of tax expenditures. The fourth summarizes the current sta¬tus of tax expenditure reporting in developing econo¬mies, with some reference to advanced economies. The last section concludes.

The purpose of this note is to provide a framework for improving tax policy design in fragile and conflict-affected states, which face political and institutional constraints. This note begins with an overview of experiences in revenue mobilization in fragile states, including relative to other country groups—in particular, nonfragile states and formerly fragile states; that is, countries that exited fragility during the period under study. A discussion follows of how the principles of tax policy design should be applied in fragile states, particularly the relative importance of the revenue objective vis-à-vis other objectives, such as equity and efficiency. The two sections that follow provide guidance on tax policy design in the emergency and consolidation phases, respectively, and discuss how governments can use tax policy to transition from one phase to another, eventually overcoming fragility. The note concludes with key lessons and a set of guiding principles for tax reform in fragile states.

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.

Analysis and comparison of taxation in different countries, looking at what tax systems have in common, how they differ and trying to explain both the similarities and the diffences. The first part concerns tax structures. The second part looks at individual taxes or related groups of taxes. The third section deals with some aspects of policy-making and tax administation.
