Digital businesses continue to grow and generate substantial revenue in market jurisdictions without maintaining a physical presence. They mainly rely on intangibles, user data and user engagement. International tax rules have not kept pace with these developments, leaving many jurisdictions unable to tax digital economic activity effectively. In response, countries have introduced national measures, such as Digital Services Taxes (DSTs), equalisation levies, and Significant Economic Presence (SEP) taxes, while continuing to engage in multilateral efforts. This paper examines how countries have implemented such measures. The study applies structured case studies of Colombia, India, Kenya, Nepal, Nigeria, and Tanzania.  It analyzes the countries’ legal frameworks, administrative practices, and revenue outcomes, while also identifying shared features and key differences in implementation approaches. The paper explores the conceptual foundations and theoretical justifications for taxing digital revenues at source, highlighting the limitations of current profit allocation rules that overlook the role of the market. Drawing from these country experiences, the study develops a peer learning framework based on emerging best practices while recognizing the challenges in implementation. The study then proposes pathways for harmonizing digital tax measures and outlines essential design elements to inform the development of the early protocol on the taxation of cross border services (which includes digital services) under the United Nations Framework Convention on International Tax Cooperation.

A Toss Up? Comparing Tax Revenues from the Amount A and Digital Service Tax Regimes for Developing Countries

By Vladimir Starkov and Alexis Jin

In this paper, we attempt to estimate the tax revenues to be gained by the Member States of ATAF, WATAF, AU and the South Centre under the Amount A and an alternative stylized DST taxation regime. Our research demonstrates that the comparative revenue effects of the Amount A and DST taxation regimes largely depend on (a) the mix of relevant domestic economic activities at market jurisdictions (i.e., revenues sourced to the country as a market jurisdiction under Amount A and the level of revenues from automated digital services generated in the country), (b) design details of the DST regime such as the DST tax rate and the nature of activities to be taxed and (c) the relief from double taxation, if any, countries will grant to domestic and foreign taxpayers under DST. This paper contains analysis relying on sources of information available to private sector researchers and it does not involve review of any information that individual taxpayers provided to tax authorities.
