Revenue Effects of the Global Minimum Corporate Tax Rate for African Economies

By Seydou Coulibaly

This policy brief provides the first piece of empirical evidence on the revenue implications of the recent global minimum tax rate reform agreement for African economies. We implement a regression discontinuity design to evaluate the effect of having an effective corporate tax rate of at least 15% on tax revenue collection for a panel of 28 African economies over the period 2000-2020.

The estimation results indicate that the implementation of the global minimum effective corporate tax rate of 15% proposed under Pillar II of the Organisation for Economic Co-operation and Development (OECD) Two Pillar Solution has a positive but not statistically significant likely impact on corporate tax revenue and total tax revenue at the conventional significance levels. This suggests that the global minimum tax deal is unlikely to increase tax revenue for African economies. These findings exhort the Inclusive Framework and all the stakeholders of the global tax reform negotiations to consider revising the global minimum tax rate rules to ensure that the agreement will effectively benefit African countries through better tax revenue collection.

Evaluating the Impact of Pillars One and Two

By Suranjali Tandon and Chetan Rao

The proposed OECD Pillar One and Two reforms mark a significant shift in the way large multinational enterprises are taxed on their global incomes. However, while considering the reform at the proposed scale tax administrators must be able to compare the revenue gains with alternatives. This paper uses open-source data to provide tentative estimates of the impact of Pillars One and Two. The methodology has been detailed so that administrators can replicate it for comparison. Further, the paper provides an assessment from the perspective of developing countries of some of the key design elements of the proposals so as to understand whether they are administrable and to foresee possible challenges.

UN Model Tax Convention: Selective Territoriality – The Specter of Privileged Player in a Rigged Game

By Muhammad Ashfaq Ahmed

This paper lays out the chessboard on which taxes on international incomes from immovables are contested, bargained, and harvested as per pre-determined rules that are starkly tilted in favor of developed countries. This embedded and pronounced bias in the international taxes regime in favor of developed countries makes them a privileged player. The developed countries then make maneuvers to optimize on their economic gains at the expense of developing nations rendering it a rigged game setting. The paper derives its rationale from an exceptionally selective choice of territoriality on incomes from immovables, which was astonishingly not aligned with the expected reverse capital movement, that is, from developing to developed countries. The genesis and evolution of selective territoriality are traced through its various institutional development phases – League of Nations (LN), Organisation for Economic Co-operation and Development (OECD), and United Nations (UN). An overwhelming international consensus on selective territoriality on incomes from immovables notwithstanding, the UN’s role is brought into spotlight to argue that the developing countries may have suffered massively over the past one hundred years by instinctively believing in the UN Model Tax Convention’s (MTC) efficacy and blindly pursuing Article 6 in their bilateral double taxation conventions (DTCs). The inimical implications of herd-mentality on part of developing countries got galvanized in the particular wake of developed countries employing innovative optimization tools – citizenship/residence by investment programs, tax havenry, manipulable ownership structures, beneficial ownership legislations, and porous exchange of information regime – to maximize on the economic gains. The paper undertakes both normative and structuralist evaluation of selective territoriality to sum up that this is an unjust principle of distribution of fiscal rights at the international level particularly in asymmetric economic relationships, and can hold its ground only until developing countries attain full cognition of the reality and start raising their vocal chords in unison to dismantle it.

Impact of a Minimum Tax Rate under the Pillar Two Solution on Small Island Developing States

By Kuldeep Sharma

The Research Paper commences with an overview of Pillar One and Pillar Two followed by detailed discussions on salient provisions of Pillar Two.

Pillar Two is envisaged to have a widespread impact on Small Island Developing States (SIDS) which are a distinct group of 38 United Nations (UN) Member States and 20 Non-UN Members/Associate Members of UN regional commissions that are exposed to unique social, economic and environmental vulnerabilities. In all, 36 SIDS that are members of the Group of Seventy-Seven (G-77) have been analysed, namely, Antigua and Barbuda, Bahamas, Bahrain, Barbados, Belize, Cabo Verde, Comoros, Cuba, Dominica, Dominican Republic, Fiji, Grenada, Guinea-Bissau, Guyana, Haiti, Jamaica, Kiribati, Maldives, Marshall Islands, Mauritius, Federated States of Micronesia, Nauru, Papua New Guinea, Samoa, São Tomé and Príncipe, Seychelles, Singapore, Solomon Islands, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Suriname, Timor-Leste, Tonga, Trinidad and Tobago, and Vanuatu.

¿Una elección difícil? Comparación de los ingresos fiscales que recaudarán los países en vías de desarrollo a partir de los regímenes del Monto A y del Artículo 12B de la Convención Modelo de las Naciones Unidas

Por Vladimir Starkov y Alexis Jin

En este documento de investigación, pretendemos calcular los ingresos tributarios que obtendrán (o perderán) los Estados miembros del South Centre y la Unión Africana con arreglo a los regímenes del Importe A y del Artículo 12B. En nuestro análisis hemos recurrido a fuentes de información disponibles para el personal investigador del sector privado, aunque no ha conllevado el examen de ninguno de los datos que los contribuyentes proporcionan a las autoridades fiscales. Nuestra investigación demuestra que los efectos comparativos en los ingresos obtenidos con los regímenes fiscales del Importe A y el Artículo 12B dependen en gran medida de a) los detalles de diseño del régimen del Artículo 12B; b) si el país es sede de empresas multinacionales que puedan estar dentro del ámbito de aplicación de los regímenes fiscales del Importe A o del Artículo 12B; y c) la desgravación a partir de la doble tributación, de haberla, que conceda el país a los contribuyentes nacionales sujetos al pago de tributos en virtud del régimen del Importe A o del Artículo 12B.

South Centre Comments on Progress Report on Amount A of Pillar One, 18 August 2022

South Centre Comments on Progress Report on Amount A of Pillar One

The South Centre offers its comments to the OECD Inclusive Framework’s Task Force on Digital Economy (TFDE) on the Progress Report on Amount A of Pillar One.

In June 2022, the Coalition for Dialogue on Africa (CODA), a Special Initiative of the African Union, and the South Centre, jointly released country-level revenue estimates from Amount A compared with Article 12B of the UN Model Tax Convention, for the 84 combined Member States of the African Union and the South Centre. CODA and the South Centre have also provided a set of recommendations to developing countries on the taxation of the digitalized economy.

The Progress Report on Amount A, the latest version of the OECD’s proposed solution for taxation of the digitalized economy, makes it clear that the revenues expected for developing countries will dwindle even further than estimated by CODA and the South Centre.

With each successive update of the rules, the proposed solution is becoming increasingly less appealing to the developing countries. The OECD must, at a minimum, release revenue estimates for the 141 jurisdictions of the Inclusive Framework such that each can take an informed decision in the national interest. As an organization that sets ‘transparency’ standards, OECD must itself be transparent and provide countries with the essential information needed for making what may become a historic decision for the international taxation regime.

A Global Asset Registry to track hidden fortunes and for asset recovery

By Ricardo Martner

Financial opacity and offshore hidden wealth have become a major economic and political problem. Tax havens continue to exist and provide financial secrecy services that allow the richest individuals in the world to hide their wealth from national tax authorities. Implementing a Global Asset Registry could help tax authorities to identify, record and tax all wealth, regardless of where it is held. It would also be a critical tool in efforts to recover stolen assets of countries suffering from widespread corruption.

Two Pillar Solution for Taxing the Digitalized Economy: Policy Implications and Guidance for the Global South

by Irene Ovonji-Odida, Veronica Grondona, Abdul Muheet Chowdhary

The taxation of the digitalized economy is the single most important topic in international tax negotiations today. The OECD has devised a “Two Pillar solution” to the problem. Pillar One is focusing on a reallocation of taxing rights to market jurisdictions, which are largely expected to be developing countries, and Pillar Two is instituting a global minimum tax. The Pillar One solution, known as Amount A, will be codified into a Multilateral Convention (MLC) and is expected to be placed before countries for signature in early 2023. The solution ushers in a new paradigm in the taxation of multinational enterprises but has immense complexity and likely minimal revenue gains for most developing countries. It will also require them to give up the right of unilateral tax measures on all out-of-scope companies, meaning they will only be able to tax the fewer than 100 companies likely to be in-scope, if at all. The decision to sign or not is thus a historic one, as it will lock developing countries into a constricted new framework, at a time when revenue needs are especially critical to recover the economies from COVID-19 in the context of a turbulent state of the global economy.

However, the United Nations too has a solution, known as Article 12B. This operates in a different manner and is a minor modification to the existing decentralized international tax system which is based on bilateral tax treaties, and which developing countries are more familiar with. It is also likely to generate far higher revenues than Amount A, and does not restrict any of their sovereign taxing rights. This Research Paper assesses the various implications for developing countries from adopting the OECD’s or the United Nations’s respective solutions and concludes with a possible global South response to the Two Pillar solution.
