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.

The Implications of Treaty Restrictions of Taxing Rights on Services, Especially for Developing Countries

By Faith Amaro, Veronica Grondona, Sol Picciotto

Taxation of cross-border services has been identified as a high priority issue in the United Nations (UN) negotiations to establish a new global framework for tax. This paper analyses the defects of international tax rules as applied to services, and their exploitation by multinational enterprises (MNEs), focusing on the impact on developing countries. Services have become increasingly important for economic development, but international tax rules favouring delivery by non-residents act as a disincentive to the growth of local services providers, particularly disadvantaging developing countries which are mainly hosts to MNEs. We analyse the restrictions on source taxation of services in tax treaties, particularly those based on the model of the Organisation of Economic Co-operation and Development (OECD), and show that their spread has been accompanied by a widening deficit in services trade of developing countries, while the weakening of their attempts to protect their tax base through withholding taxes has resulted in increasing losses of tax revenue. The paper combines detailed qualitative analyses of tax treaties with quantitative estimates of their effects on trade and tax revenues for services of five developing countries: Argentina, Brazil, Colombia, Kenya and Nigeria. Our analysis suggests that a new approach is needed for taxation of services, breaking with the residence-source dichotomy, and adopting formulary apportionment. This could be based on the standards agreed in the Two Pillar Solution of the OECD/Group of Twenty (G20) project on base erosion and profit shifting (BEPS) and developed now through the UN.

Taxation of the Digital Economy 

by Adnan Sose, Nicolás Tascon and Anders Viemose

As globalisation has pushed through complex inter-State trade in goods and services, in parallel there is a growing complexity in determining the taxation of Multinational Enterprises (MNEs) in an increasingly digitalized economy. This report reviews existing bilateral tax treaties between South Centre’s Member States and States where most digitalised MNEs are headquartered, using a threshold of EUR 750 million in annual turnover to limit the number of in-scope MNEs in the study. This analysis produced primary data on South Centre Member States’ source taxing rights scores and the implications of this on tax treaty negotiations to enable effective taxation in the digital economy through the inclusion of the United Nations (UN) solution for digital taxation, Article 12B of the UN Model Tax Convention. Further, the study sought to identify ‘weak’ tax treaties with low source taxing rights which merited a comprehensive renegotiation beyond the inclusion of Article 12B. Furthermore, the reports examined the treatment of “Computer Software” in the tax treaties under study, and concluded with recommendations going forward.

Inequalities in Taxing Rights

Thursday, 16 December 2021, 02:00 PM (South African Standard Time), Virtual Meeting

The Coalition for Dialogue on Africa (CODA) and the South Centre, together with other key stakeholders are co-organizing a series of dialogues to discuss and address the issues related to stemming IFFs from Africa.

The main objective of this dialogue series is to bring together key stakeholders to discuss the current global processes towards combatting IFFs, re-allocation of taxing rights, the role of African regional institutions, the importance and place of Africa’s voice and representation in these processes.

The dialogue series will examine the legitimacy of these processes, including the nature of Africa’s representation in the global conversations and the outcome of the processes with respect to Africa’s interest.

The Place of Multilateralism in Tax Reforms: Exclusionary Outcomes of a Purported Inclusive Framework

By Alexander Ezenagu

Countries have come to accept the wide application of international tax rules in both their domestic and international tax affairs. However, where international tax rules fall short of the legitimate expectations of countries and fail to provide necessary guidance, countries may be compelled to seek other sources of guidance. In this paper, it is argued that in the absence and failure of international tax rules to provide adequate guidance and encourage a fair tax system, countries should not be prohibited from exercising their fiscal sovereignty.
