Inputs to the Outcome Document

By grounding policy decisions in solid evidence, countries can better navigate the complexities of tax reforms and ensure that their strategies effectively support the financing of the SDGs. Administrative data and ex-ante policy modelling, such as tax-benefit microsimulation modelling, are indispensable in providing a full picture to policymakers. Data and modelling infrastructure should be public goods accessible to the government and its agencies, academia, think tanks and CSOs to enable an inclusive debate about the choices governments face when making decisions on tax and benefit policies.

Asia-Pacific experience suggests a central role of rationalized tax structure, strengthened tax administration, and reduced wasteful tax exemptions in episodes of swift tax revenue enhancement. Nevertheless, to achieve greater and sustained results in the longer term, broader socioeconomic progress and improvements in public governance are equally indispensable. Meanwhile, better exploration of tax potentials of direct income and wealth taxes and of the region’s booming real estate markets will be key for further public revenue enhancement.
