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.
To realize their domestic revenue potential, countries need research and technical cooperation. International organizations and bilateral donors provide essential training and resources to strengthen tax administrations and skills for policy analysis in government and academia. Governments in the Global South can progress faster towards the SDGs by partnering with experienced institutions. Technical assistance and research collaboration are key, with hands-on learning from experts.
