Tax Administration and Compliance

Many of the challenges low-income countries face in mobilising domestic resources are related to tax administration as much as tax policy. Our research on this theme encompasses all aspects of tax administration, from technology adoption, to data management and strategies for collecting revenue from different types of taxpayers. Tax compliance is a key focus, as low-income countries struggle with widespread evasion, corruption, and limited administrative capacity. Our research on compliance includes survey-based studies of taxpayers’ perceptions and attitudes, case studies, and large-scale field experiments.

Are Women More Tax Compliant than Men? How Would We Know?
by Jalia Kangave, Ronald Waiswa & Nathan Sebaggala

Most research on tax compliance, including research on gender differences in compliance, is based on one of two problematic sources of data. One is surveys enquiring about attitudes and beliefs about taxpaying, or actual taxpaying behaviour. The other is experiments in which people who may or may not have experience of paying different types of…

Using administrative data to assess the impact of the pandemic in low-income countries: An application with VAT data in Rwanda
by Giulia Mascagni & Adrienne Lees

This paper uses administrative data from Value Added Tax (VAT) returns to provide insights on the impact of the COVID-19 pandemic in Rwanda. We show that the lockdown in Rwanda had a severe impact on the domestic economy, despite relatively low case numbers. However, the economy quickly rebounded after restrictions were lifted, with overall sales…

Tax Compliance in Rwanda: Evidence from a Message Field Experiment
by Giulia Mascagni & Christopher Nell

In early 2016 the Rwanda Revenue Authority sent messages to 9,000 taxpayers, aimed to encourage compliance. Each taxpayer was randomly allocated to a treatment group, or to a control group that received no message. Treatment messages varied in terms of content (deterrence, fiscal exchange, reminder) and delivery method (letter, email, SMS). Our RCT evaluates the…

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….

Simulating the Impact of COVID-19 on Formal Firms in South Africa
by Adrienne Lees, Giulia Mascagni & Michael Kilumelume

This note uses administrative tax data for formal firms to measure the direct impact of lockdown restrictions on firms’ profitability, employment, and exit rates. The authors separate the economy into three categories, according to the size of the shock experienced, and consider two lockdown scenarios: one lasting three months and one lasting five months. These…

How Effective has the TADAT Framework Been in Improving Tax Administration in Uganda?
by Doris Akol, Margaret Magumba, Patrick Loke, Milly Nalukwago Isingoma & Tina Kaidu

Like several other revenue administrations, prior to the introduction of the Tax Administration Diagnostic Assessment Tool (TADAT) in Uganda, there was no comprehensive standard tool for assessing revenue administration against internationally recognised good practices. Detailed assessment was spread across different facets of revenue administration and indicators were not standardised. The first TADAT assessment of Uganda’s…

Gender and Tax Compliance: Firm Level Evidence from Ethiopia
by Seid Yimam & Fissha Asmare

Many Sub-Saharan African countries, characterised by government budget deficits, have been undergoing reforms and improvements to enhance tax revenue collection. However, such improvements often fall short of expectations and do not yield the expected revenue. These economies are highly vulnerable to tax avoidance and tax evasion, mainly due to the lack of a strong, modernised…

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 several respects, they are, on average, more reformed and more efficient than tax administrations in other low-income regions. Many have made major organisational changes, responding effectively to a number of major challenges. This includes the introduction of VAT, a rather complex…

What is the connection between taxation and more open societies that the British aid programme aims to support? In long-term historical perspective, it is very close. The societies that enjoy the most open, democratic and accountable government are also those that tax the most – and spend the most on making life better for their…

Informal economies in North Africa have frequently captured public attention in recent years. They not only make up over half of the region’s labour force and a substantive part of its GDP, but often put workers into unsafe environments or in conflict with authorities. While Mohamed Bouazizi’s self-immolation is surely the most famous example, deaths and…

Domestic revenue mobilization is a priority for many SSA countries. Yet, low tax compliance constitutes a major challenge to this drive. Improving tax compliance will require an understanding of the underlying factors influencing a taxpayer’s decision to either pay taxes or not. However, little is known about tax compliance behaviour in most SSA countries; insights…

Does Gender Matter in Tax Compliance? The Case of URA’s Individual Taxpayers
Project Researchers: Ronald Waiswa, Uganda Revenue Authority, Nathan Sebaggala & Jalia Kangave, ICTD

There is now an extensive body of literature looking into the factors that influence tax compliance. These studies, loosely known as tax morale studies, employ various tools to understand why some people pay taxes while others do not. In some cases, the studies are gender disaggregated, thereby enabling us to understand how men and women…

Improving State Taxation Capacity using Administrative Data
Project Researchers: Aprajit Mahajan, JPAL-South Asia, Shekhar Mittal & Ofir Reich

Improving the state’s ability to tax effectively is central to the development process. However, tax collections (as a percentage of GDP) are low in most developing countries — in India the ratio is about 15% — and non-compliance is widely seen as an important problem. A common strategy to evade taxes is to establish shell…
