The Contested Shaping of International Tax Rules: The Growth of Services and the Revival of Fractional Apportionment

by Sol Picciotto

The digitalisation of the economy has spotlighted fundamental flaws in international tax rules, which have been exacerbated since the 1970s with the wider shift to the services economy and the growth of international services. These systemic flaws have been more evident from the perspective of countries that are mainly importers of services that have tried…

There and Back Again: The Making of Uganda’s Mobile Money Tax

by Doris Akol & Adrienne Lees

This paper evaluates the appropriateness of the tax policymaking process that led to the introduction, and the later adaptation, of a tax on mobile money transactions in Uganda in 2018. We examine the unusual source of the proposal, how this particular tax diverged from the usual tax policymaking process, and whether certain key stakeholders were…

The Role of Social Influence in Enforcing Tax Compliance: Experimental Evidence from Nigeria

by Adedeji Adeniran, Mma Amara Ekeruche & Chukwuka Onywkwena

Economic development is linked with increased state capacity including the ability to mobilise domestic tax resources. For many developing countries, high levels of informality are a major constraint in this regard. Yet, economic incentives like changing the tax rate or increasing the filling and audit rate can be ineffective in a highly informal economic structure….

Taxing Agricultural Income in the Global South: Revisiting Uganda’s National Debate

by Graeme Stewart-Wilson & Ronald Waiswa

The issue of agricultural taxation has almost completely disappeared from the scholarly and policy agendas in recent decades. And yet, agriculture is taxed very lightly despite contributing substantially to GDP across many Global South countries today. In some cases, light-touch taxation may be necessary to encourage investment in the sector and to protect small and…

Taxation and Customs Reforms in Fragile States: Between Bargaining and Enforcement

by Thomas Cantens & Gael Raballand

This paper explores why taxation reforms are so different in fragile states, the conditions in which they occur, and what can be done to make these reforms more successful – including contributing, whenever possible, to state-building. Based on extensive engagement and fieldwork in the Sahel and other regions in sub-Saharan Africa (including Central and West…

Profit Shifting of Multinational Corporations Worldwide

by Javier Garcia-Bernardo & Petr Janský

Multinational corporations (MNCs) avoid taxes by shifting their profits from countries where real activity takes place towards tax havens, depriving governments worldwide of billions of tax revenue. Earlier research investigating the scale and distribution of profit shifting has faced methodological and data challenges, both of which we address. First, we propose a logarithmic function to…

Explaining Informal Taxation and Revenue Generation: Evidence from south-central Somalia

by Vanessa van den Boogaard & Fabrizio Santoro

Most people in low-income countries contribute substantially to the financing of local public goods through informal revenue generation (IRG). However, very little is known about how IRG works in practice. We produce novel evidence on the magnitude and regressivity of IRG and its relationship with the state in a fragile context, Somalia. We rely on…

The VAT in Practice: Equity, Enforcement and Complexity

by Giulia Mascagni, Roel Dom & Fabrizio Santoro

The value added tax (VAT) is supposed to be a tax on consumption that achieves greater economic efficiency than alternative indirect taxes. It is also meant to facilitate enforcement through the ‘self-enforcing mechanism’ – based on opposed incentives for buyers and sellers, and because of the paper trail it creates. Being a rather sophisticated tax,…

Tax Certainty? The Private Rulings Regime in Uganda in Comparative Perspective

by Samuel Kahima, Solomon Rukundo & Victor Phillip Makmot

Taxpayers sometimes engage in complex transactions with uncertain tax treatment, such as mergers, acquisitions, demergers and spin-offs. With the rise of global value chains and proliferation of multinational corporations, these transactions increasingly involve transnational financial arrangements and cross-border dealings, making tax treatment even more uncertain. If improperly structured, such transactions could have costly tax consequences….

At the Table, Off the Menu? Assessing the Participation of Lower-Income Countries in Global Tax Negotiations

by Rasmus Corlin Christensen, Martin Hearson & Tovony Randriamanalina

Since 2013, the formal structure of global corporate tax policymaking at the OECD has changed. Decisions are no longer made by 37 OECD members, but by 137 countries from all regions and levels of development through the ‘Inclusive Framework’ (IF). Official documentation emphasises that all countries participate on an ‘equal footing’, but some participants and…

Strengthening Tax-Accountability Links: Fiscal Transparency and Taxpayer Engagement in Ghana and Sierra Leone

by Vanessa van den Boogaard, Wilson Prichard, Rachel Beach & Fariya Mohiuddin

There is increasingly strong evidence that taxation can contribute to expanded government responsiveness and accountability. However, such positive connections are not guaranteed. Rather, they are shaped by the political and economic context and specific policies adopted by governments and civil society actors. Without an environment that enables tax bargaining, there is a risk that taxation…

Gender and Tax Compliance: Firm Level Evidence from Ethiopia

by Seid Yimam & Fissha Asmare

Developing countries often lack tax information and enforcement capacity necessary to effectively implement instruments of a modern tax system, such as VAT, income taxes and others. An alternative strategy to increase tax compliance, and thus revenue, in these countries may depend on the capacity of policymakers to harness individual’s civicmindedness, social norms, reciprocity and cultural…
