Analysing the Impact of UN and OECD Subject to Tax Rule for G-24 and South Centre Member States
By Suranjali Tandon and Chetan Rao
The Subject to Tax Rule (STTR) is meant to address base erosion and profit shifting in cross –border transactions. The United Nations (UN) and Organisation for Economic Co-operation and Development (OECD)/Group of Twenty (G20) Inclusive Framework have developed models of the STTR that countries may choose to adopt in their treaties. This paper provides a review of these designs of two STTR models and proceeds to estimate the revenue gains for the Intergovernmental Group of Twenty-Four on International Monetary Affairs and Development (G-24) and South Centre Member States that may arise from a STTR that covers different kinds of payments. The OECD STTR is limited to related-party payments and imposes thresholds based on mark-up and materiality, reducing its applicability in practice. In contrast, the UN STTR offers broader coverage, applies to both related and unrelated parties, and does not impose restrictive thresholds, making it more administratively feasible for developing countries. Although the estimated gains from the OECD STTR appear modest due to its narrow scope, the UN STTR shows greater potential. The analysis also highlights data limitations and the need for access to microdata for accurate country-level assessments.

Will the Pact for the Future Advance a Common Global Agenda on the Challenges Facing Humanity?
By Viviana Munoz Tellez, Danish, Abdul Muheet Chowdhary, Nirmalya Syam, Daniel Uribe
At a time when multilateralism is needed more than ever to address the global challenges and rising geopolitical tensions, paradoxically, the capacity and delegated power of the United Nations (UN) to uphold a rule-based order to keep peace and security is being weakened. Even in an increasingly multipolar world, a retreat towards unilateralism by world powers masked as national sovereignty is dangerous and highly unfavourable for developing countries. In this light, the United Nations Pact for the Future, a new forward-looking agenda of commitments adopted by consensus by UN Member States in September 2024, is a welcome initiative. The Pact for the Future, nonetheless, is short in delivering commitments on transformative changes in global governance and solutions to the most pressing global challenges. This document briefly examines some of the actions and high-level commitments in the Pact of the Future to strengthen multilateral cooperation and provides recommendations for their implementation.
The draft contains six principles, and detailed commentary to elaborate on each principle and direct stakeholders to additional resources. The principles are meant to help policymakers and other stakeholders navigate the policy, legislative and administrative issues related to tax incentives, with a particular focus on the circumstances of developing countries. The consultation process invited input on the draft’s content, coverage, applicability, and recommendations for refinement.
Towards a UN Protocol for Taxing Cross-Border Services in a Digitalized Economy
By Abdul Muheet Chowdhary, Anne Wanyagathi Maina and Kolawole Omole
This Policy Brief offers a way forward on the United Nations Framework Convention on International Tax Cooperation’s (UNFCITC) protocol for taxing cross-border services in a digitalized economy. Such a protocol can provide a way to standardize and harmonize the existing plethora of widely varying Digital Services Taxes (DSTs), which can reduce political tension between the Global North and South, ease compliance costs and uncertainties for business, while providing a basis for the elimination of double taxation. The revenue generated can help bridge the Sustainable Development Goals (SDGs) financing gap and for the realization of human rights in the Global South. The Group of Twenty (G20) can act as a forum where key countries in the North and South can hammer out the architecture of the protocol for taxing cross-border services.

The upcoming 4th conference on financing for development (FfD4) represents an important opportunity for developing countries to achieve a deep reform of the international financial architecture so that it meets their sustainable development needs and enhances the scale of development finance to fully realize the 2030 Agenda for Sustainable Development.

Determining the Upper Bound of the Scoping Criteria for Amount B in the OECD/G20 Two-Pillar Solution: A Policy Guide for Developing Jurisdictions
By Chetan Rao, Ruchika Sharma, and Dr. Vijit Patel
Amount B, a component of the OECD/G20 Two-Pillar Solution, has been designed to simplify transfer pricing for baseline distribution activities. With the aim of developing a practical policy guide for developing jurisdictions to fine tune the quantitative scoping criterion under Amount B, i.e., “annual operating expense to annual net revenue” ratio, this paper critically analyses various aspects of this criterion. The upper bound of this ratio is purported to help jurisdictions in identifying baseline distributors. It is currently set as a flexible range from 20% to 30%, with the choice available to each adopting jurisdiction deciding the exact point in the range for implementation of Amount B within its jurisdiction. Given the lack of any data-backed rationale in the Amount B report for development of this range, the authors suggest that the upper bound range might have been politically negotiated. For this very reason, developing countries need to tread carefully while setting the upper-bound and consider both its tax as well as policy implications. Through an empirical analysis of independent distributors in India, the paper highlights the link between the upper bound, functionality, and profitability, illustrating how these metrics impact developing countries with lower asset and expense intensities. The findings suggest that setting the upper bound at the higher end of the range could unintentionally bring above-baseline distributors into scope, thus foregoing long-term taxing rights for developing jurisdictions. Through this analysis, the paper offers practical insights and recommendations for jurisdictions, especially developing ones, for setting this upper bound to protect their taxing rights and minimize risks of misclassification of above-baseline distributors as baseline.
