Assessing how Asia and the Pacific can benefit from stronger tax systems, this comparative analysis drills down into the set-ups and performance of revenue bodies in 41 economies to highlight reform challenges and outline opportunities. Drawing on the results of the International Survey on Revenue Administration (ISORA 2022) survey, it provides background on each economy, details the performance of their revenue bodies, and looks at growing digitalization. The seventh edition in the series, it outlines major trends and sets out ways governments and officials can reform their revenue bodies to build more effective and efficient tax systems.

Improved tax systems can help countries in Asia and the Pacific generate the resources needed to implement the Sustainable Development Goals. This report provides information on current tax administration practices in the region to help governments identify opportunities to strengthen their tax systems. It analyzes the administrative frameworks, practices, and performance of revenue bodies in 34 economies. The analysis was largely based on survey data gathered by the Asian Development Bank in collaboration with the Organisation for Economic Co-operation and Development and the International Monetary Fund.

This report is the twelfth edition of the OECD's Tax Administration Series. Containing a wealth of data and other information from 58 jurisdictions, it is intended to be used by tax administration analysts allowing them to understand the design and administration of tax systems in other jurisdictions and to draw cross-border comparisons. While primarily aimed at analysts, it can also be a useful tool for senior tax administration managers or officials in ministries of finance when considering changes in tax system administration. The 2024 edition includes performance-related data, ratios and trends up to the end of the 2022 fiscal year. For the first time since 2019, this edition also examines in more detail the administrative, operational and organisational practices of participating tax administrations. Finally, it contains a special feature which explores how tax administrations are estimating tax gaps. The underlying data for this report comes from the International Survey on Revenue Administration, and in certain areas it also uses information from the Inventory of Tax Technology Initiatives.

Revenue Statistics in Asian and Pacific Economies is jointly produced by the Organisation for Economic Co-operation and Development (OECD)’s Centre for Tax Policy and Administration (CTP) and the OECD Development Centre (DEV) with the co-operation of the Asian Development Bank (ADB), the Pacific Island Tax Administrators Association (PITAA), and the Pacific Community (SPC) and the financial support of the European Union and the government of Japan.

This paper presents the results of the International Survey on Revenue Administration (ISORA) deployed during 2016 and covering fiscal years 2014 and 2015. It is made possible by the participation of 135 tax administrations from around the world that provided data.

The IMF Fiscal Affairs Department’s Revenue Administration Gap Analysis Program (RA-GAP) assists revenue administrations from IMF member countries in monitoring taxpayer compliance through tax gap analysis. The RA-GAP methodology for estimating the VAT gap presented in this Technical Note has some distinct advantages over commonly used methodologies. By using a value-added approach to estimating potential VAT revenues, as compared to the more traditional final consumption approach used by most countries undertaking VAT gap estimation, the RA-GAP methodology can provide VAT compliance gap estimates on a sector-by-sector basis, which assists revenue administrations to better target compliance efforts to close the gap. In addition, the RA-GAP methodology uses a unique measurement for actual VAT revenues, which isolates changes in revenue performance that might be due to cash management (e.g., delays in refunds) from those due to actual changes in taxpayer compliance.

This paper examines the role of tax administration in developing countries from an economic perspective. The traditional separation of tax policy and tax administration in the literature is shown to break down in developing countries, where tax administrators decide in what manner complicated tax legislation should actually be applied. After surveying economic literature dealing with tax administration, the paper offers guidelines on how tax administrators can help implement more efficient and equitable tax systems.

Taxation is increasingly in the limelight as a development agenda item, particularly with the emergence of the G20 as the premier international forum. This volume highlights the challenges faced by the Asia and Pacific region regarding tax policy and administration. Partly reflecting the diversity of the region, the region’s voice still appears to be low in comparison with that of other regions such as Europe and Latin America. This book introduces ADB’s and ADBI’s active roles in assisting developing countries with respect to taxation. In addition, this book is an attempt to narrow the gap in understanding between development specialists and tax specialists. This publication, an anthology by contributors who have been involved in ADB’s and ADBI’s activities on fiscal policy and taxation in various capacities is classified into three groups: (i) bird’s-eye overviews that discuss tax and development issues in Asia and the Pacific; (ii) country case studies that present theoretical policy analysis of a particular economy; and (iii) another set of country case studies that share practical experiences regarding the tax system of a particular economy.

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.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.
