This paper presents Islamic Republic of Mauritania’s 2024 Article IV Consultation, Third Review under the Arrangement’s under the Extended Credit Facility and Extended Fund Facility, Request for Modification of Quantitative Performance Criteria, and Second Review under the Resilience and Sustainability Facility (RSF) Arrangement. The Mauritanian economy has remained resilient, with economic growth projected to slow to 4.6 percent in 2024. Growth is expected to remain favorable in the medium term. Enhancing revenue mobilization, strengthening banking supervision, and sustaining the implementation of the national governance action plan would support private sector-led inclusive growth. Program performance has been strong. Mauritania’s reform drive and sound macroeconomic management have helped strengthen debt sustainability and resilience to shocks, while creating policy space for pressing infrastructure and social spending. Continued implementation of the ambitious climate change adaptation and mitigation reform measures, supported by the RSF, will help address Mauritania’s medium- and long-term term challenges and catalyze additional financing.

The paper examines domestic revenue mobilization in Mauritania and proposes strategies to enhance tax revenue collection to address fiscal sustainability challenges and finance critical investment projects. Despite recent progress, Mauritania’s tax-to-GDP ratio remains below that of its peers, constrained by a complex legal framework, numerous derogatory tax regimes, and inefficiencies in revenue administration. The analysis indicates that Mauritania could increase tax revenues by up to 3.4% of GDP in the medium term, thus reducing its tax gap by one-third. Key policy recommendations include reducing VAT exemptions, replacing corporate tax exemptions with cost-based incentives, reforming the personal income tax system, broadening the consumption tax base, simplifying tax procedures, managing tax arrears more effectively, and strengthening tax compliance.

The Ministry of Finance has developed the Public Finance Reform Master Plan 2021-2025 (SD-RFP 2021-2025), which aims to set strategic orientations for reforms and operational guidelines for their implementation over a five-year period. The masterplan includes objectives for the General Directorate of Customs (GDC) reform, focusing on revising customs law, enhancing revenue collection, and combating fraud.

The IMF’s Fiscal Affairs Department has been working with Mauritania on capacity building in tax policy. Mauritania has recently created a tax policy unit and adopted a new General Tax Code in 2019 with a corporate income tax and a semi-dual approach to personal income taxation. However, there is significant scope to enhance the efficiency and effectiveness of income taxes, including due to the proliferation of wasteful tax exemptions. The fast urbanization also calls for a review of recurrent property taxation. The formalization of property rights requires a temporary suspension of the excessive registration fees. Consumption taxation can also be improved by broadening the tax base, for example, by abolishing regressive value-added tax exemptions or by imposing excise taxes on imported used vehicles. Finally, several recommendations aim to support the reform of the Mining Code, such as introducing some progressivity, prohibiting the negotiation of any tax parameters, and strengthening the principle of ring-fencing.

This paper has identified four episodes of large and sustained revenue mobilizations in Sub-Saharan Africa (SSA) and found common lessons from the episodes. Although there is no one-size-fits-all strategy, we can find a tax reform path suitable to Nigeria’s circumstances. Based on these cross-country experiences, this paper recommends: (i) implementing a package reform of tax administration and tax policy measures; (ii) focusing mainly on indirect tax (VAT and excise) reforms and tax incentive rationalizations; (iii) undertaking tax administration measures for improving compliance by strengthening taxpayer segmentation and automation; and (iv) launching social dialogue with key stakeholders as well as high-level political commitment.

This Selected Issues paper presents stylized facts about food insecurity in Nigeria, investigates its drivers in a cross-country setting, and assesses the role of policies. The paper describes regional aspects of Nigeria’s food insecurity and compares the impact of coronavirus disease 2019 and the war in Ukraine on food security in Nigeria and other countries. It also provides an overview of agricultural production and consumption in Nigeria. The paper investigates the drivers of food security using an empirical cross-country framework including demand, supply, and price factors, and offers thoughts on policies to improve agricultural yields and production. The important role of inputs is evident in the policy experience of comparator countries. Nigeria has achieved a substantial increase in agricultural production associated with its policies but some have been less successful. Import dependency for key staples has not fallen and the cost of these agricultural products remains driven by international prices. Further, central bank credit to the agricultural sector has not succeeded in increasing production beyond the stimulus of high rainfall and high food prices.

This paper discusses key legal issues in the design of Board Oversight in central banks. Central banks are complex and sophisticated organizations that are challenging to manage. While most economic literature focuses on decision-making in the context of monetary policy formulation, this paper focuses on the Board oversight of central banks—a central feature of sound governance. This form of oversight is the decision-making responsibility through which an internal body of the central bank—the Oversight Board—ensures that the central bank is well-managed. First, the paper will contextualize the role of Board oversight into the broader legal structure for central bank governance by considering this form of oversight as one of the core decision-making responsibilities of central banks. Secondly, the paper will focus on a number of important legal design issues for Board Oversight, by contrasting the current practices of the IMF membership’s 174 central banks with staff’s advisory practice developed over the past 50 years.

Presumptive income taxes in the form of a tax on turnover for SMEs are pervasive as a way to reduce the costs of compliance and administration. We analyze a model where entrepreneurs allocate labor to the formal and informal sectors. Formal sector income is subjected either to a corporate income tax or a tax on turnover, depending on whether their turnover exceeds a threshold. We characterize the private sector equilibrium for any given configuration of tax policy parameters (corporate income tax rate, turnover tax rate, and threshold). Given private behavior, social welfare is optimized. We interpret the first-order conditions for welfare maximization to identify the key margins and then simulate a calibrated version of the model.

This note discusses administrative measures that can be implemented by customs administrations of low-income and fragile countries in a short period (about a year) to improve traders’ compliance and improve revenue collection. These suggested actions have been identified based on the experience acquired through the International Monetary Fund’s (IMF) Fiscal Affairs Department’s (FAD) technical assistance (TA), particularly the findings and recommendations of TA missions to sub-Saharan African countries. Strengthening low-capacity customs administrations requires structural reforms to support the effective implementation of defined strategies. Developing core operational functions such as risk management, audit, investigation and intelligence are good examples of such reforms. Modernizing human resource management policies or achieving a fully automated environment in a customs administration are longer-term reform projects. Long-term reforms are not addressed here. The note focuses on targeted actions with a potential to increase trade revenue in the short term, and which can be taken without mobilizing large resources or engaging in a broad reorganization. It is hoped that the suggestions in this note will help stakeholders, including country authorities, customs management, donors and TA partners, area departments of the IMF, FAD, and the IMF regional TA centers, identify, design, and implement short-term changes in customs administrations. If implemented effectively, these changes should contribute to a noticeable improvement of revenue performance.
