Session on Tax Trends in Asia

Several countries in Asia and the Pacific face significant revenue mobilization challenges against the backdrop of spending needs, including financing development goals. This session provides an overview of the stylized facts and recent trends in revenue mobilization: What has been the progress so far? What are the latest trends in revenue mobilization across countries in the region? How does the tax mix evolve and how is that related to policy and administrative changes? And how do countries compare to one another, as well as compare with countries in other regions? What plans are being prepared to advance revenue efforts?

Session on International Taxation  

Pillar 2 of the Inclusive Framework Agreement on the 2-pillar reform of the international tax framework is currently being implemented by several countries. This could have profound effects for all countries, including those who have not yet implemented the new rules or who are not part of the agreement. The session will discuss the implications for developing countries, including for revenue, investment and the economy. It will also discuss how countries can best respond to the new circumstances, including through building capacity in the revenue administration to cope with international tax issues, adopting simplified measures to protect the domestic tax base, and by reforming domestic policies, such as investment tax incentives. The session will also discuss issues that should feature on the future international tax agenda from the perspective of developing countries.

Session on Taxation of High-Income Individuals 

High- and rising-income and wealth inequality is increasingly recognized as a major concern for countries. While inequality at the bottom can often be addressed through targeted tax and spending policies, progressive tax systems are believed to be well-placed to address inequality at the top of the income distribution. Both wealth taxes and capital income taxes – which can be designed in different shapes and forms – have received renewed attention across the world recently. This session will discuss the merits and drawbacks of these different taxes (the effects on revenue, income distribution and the economy), experiences across countries, and administrative issues (the role of international information exchange, voluntary disclosure programs, and high-wealth individual units).

Session on Carbon Pricing 

Climate change poses major challenges to economic growth and development in the world economy as well as macroeconomic policy making. Asia is no exception with temperatures rising two times faster than the global average and an increased frequency and severity of weather-related natural disasters. To support climate change mitigation strategies, countries in Asia are increasingly turning to carbon pricing and other complementary instruments. This session discusses the expected implications of carbon pricing and how countries can address political concerns with their introduction, followed by sharing country experiences with carbon pricing schemes in Asia and lessons learned.

Session on Building Tax Capacity through Governance and Accountability 

To mobilize revenue effectively and efficiently, it is essential that the tax system is fair and adequately enforced and that people have trust in its institutions. This requires the combination of a well-designed and coherent policy framework, transparent policies and institutions, and good governance by people with appropriate technical and human skills. Building a good institutional and governance framework and maintaining its credibility over time can be challenging, however. The session will discuss the features of a good governance and accountability framework, both on the design of policies (including the required information, data, analysis and organization) and its implementation (organization, core processes, compliance management, digitalization). Countries will share experience on best practices.

Session on Digitalization and Artificial Intelligence 

Digitalization has been transforming tax administration practices over recent decades and generative AI promises to further revolutionize this. These changes go well beyond adopting new technologies – they require a transformation of organizations, people, processes and relationships with customers. While sometimes successful, digitalization also often fails to deliver its potential. This session will address the broader context of digital transformation, ranging from data integrity, information security, increasing ICT expenditures and navigating competing reform priorities. Countries will share experiences regarding emerging implications of AI in tax administration, including how to deal with challenges.  Selected AI challenges and opportunities for tax administrations will also be addressed. Moreover, the session will cover the tax policy implications of digitalization.
