For ADB members in Asia and the Pacific, stronger tax systems are now more important than ever—to boost revenues enabling recovery from the economic shocks of COVID-19, and to reinforce implementation of Sustainable Development Goals. Using comparative data up to the fiscal year 2020, and drawing from the International Survey on Revenue Administration (ISORA 2021), this sixth edition in our series analyzes the administrative setups and performance of revenue bodies in 40 economies across the region—to help governments and officials identify promising options for building more efficient, inclusive 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 5th edition of ADB’s A Comparative Analysis of Tax Administration in Asia and the Pacific. It provides internationally comparative data on aspects of tax systems and their administration in 38 economies and detailed analysis of the comparative results across the region, aiming to assist the revenue bodies to improve their performance by providing opportunities to benchmark their administration against similar economies in the region. The comparable data and analysis are based largely on the 2020 round of the International Survey on Revenue Administration, for the 2018 and 2019 fiscal years.

This comparative analysis report, the second in a series, is part of ADB’s regional research and development project on tax administration that analyzes the administrative frameworks, functions, and performance of 21 economies in Asia and the Pacific. The initial version of this report was published in 2014. The primary objective of the series is to motivate governments and revenue officials by sharing knowledge of important developments and trends in tax administration practice and performance, and to identify opportunities to enhance the operation of their tax systems.

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.

This report is the eleventh edition of the OECD's Tax Administration Series. It provides internationally comparative data on aspects of tax systems and their administration in 58 advanced and emerging economies.

A robust and sustainable tax system requires good tax administration. This report compares the administrative frameworks, functions, and performances of tax administration bodies in 22 jurisdictions in Asia and the Pacific. The descriptive analysis is based on surveys of tax administration conducted in 2012 and 2013. The surveys attempt to provide internationally comparable data on aspects of the sample jurisdictions' tax systems and their administration. Tentative conclusions emerge from the descriptive and comparative analysis.
