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…

How to Best Nudge Taxpayers? The Impact of a Tailored Letter Experiment in Eswatini

by Fabrizio Santoro, Edward Groening, Winnie Mdluli & Mbongeni Shongwe

Very little is known about why taxpayers in sub-Saharan Africa (SSA) remit their taxes. In collaboration with the Eswatini Revenue Authority (SRA), this study implements a nationwide randomised controlled trial nudging more than 20,000 income tax payers with behaviourally-informed mailings. This study attempts to shed new light on the drivers of SSA taxpayers’ compliance, and…

What is Wrong with African Tax Administration?

by Mick Moore

National tax administrations in sub-Saharan Africa have undergone considerable reform in recent decades. In a number of respects, they are, on average, more reformed and more efficient than tax administrations in other low income regions of the world. They have responded effectively to a number of major challenges. However, we now have evidence from benchmarking…

To File or Not To File? Another Dimension of Non-Compliance: The Eswatini Taxpayer Survey

by Fabrizio Santoro, Edward Groening, Winnie Mdluli & Mbongeni Shongwe

Non-filing refers to taxpayers who fail to submit a tax declaration, thus becoming ghosts in the eyes of tax authorities. It is a widespread phenomenon in sub-Saharan Africa, and has a number of detrimental fiscal effects. Non-filing has been largely unexplored in the literature, which focusses more on active filers. The overall aim of this…

Tax Compliance of Wealthy Individuals in Rwanda

by Jalia Kangave, Kieran Byrne & John Karangwa

Low-income countries are increasing their fiscal independence through the improvement of domestic taxation systems. To continue to do so, they must ensure that these systems are perceived as equitable and preserve their integrity. An essential characteristic of an equitable tax system is the treatment of wealthy individuals. In this paper, we use key informant interviews…

A Simplified Method for Taxing Multinationals for Developing Countries: Building on the ‘Amount B’ Proposal to Repair the Transactional Net Margin Method

by Michael C. Durst

This paper considers whether the ‘Amount B’ proposal currently being negotiated in the Inclusive Framework, for the attribution of fixed remuneration for the ‘routine’ distribution and marketing activities of MNE affiliates, may offer a useful template for the re-working of the widely used ‘transactional net margin’ transfer pricing method (TNMM). The TNMM has for years…
