“Domestic resource mobilization is the process by which developing country governments expand their capacity to generate revenue from domestic sources primarily taxation to finance public investment and development without dependence on external aid or debt.” DRM addresses the structural financing gap that makes developing countries perpetually dependent on ODA and borrowing: if governments can collect a larger and more equitable share of national income, they gain fiscal space to fund public goods independently. Average tax-to-GDP ratios in low-income countries hover around 15%, versus 33% in OECD countries a gap that represents hundreds of billions in annually uncollected revenue.
Executive Summary
The Addis Ababa Action Agenda (2015) placed DRM at the center of the Financing for Development framework, recognizing that ODA will never close the development financing gap and that domestic fiscal capacity is the foundation for sustainable public service delivery. The IMF estimates that low-income countries could increase tax revenues by 2-4 percentage points of GDP through improved administration and policy reform equivalent to a doubling of current ODA flows. Illicit financial flows, estimated at $1-2 trillion annually flowing from developing countries, represent the most significant structural drag on DRM.
The Strategic Mechanism
- Tax administration reform: Modernizing revenue authority systems, reducing corruption, and improving compliance through technology (e-filing, e-invoicing, risk-based audit).
- Tax policy reform: Broadening tax bases by reducing exemptions, improving property taxation, expanding VAT coverage, and introducing wealth and capital gains taxes.
- International tax cooperation: Implementing OECD BEPS frameworks, country-by-country reporting, and exchange of tax information to curb profit shifting.
- Curbing illicit financial flows: Anti-money laundering measures, transfer pricing rules, beneficial ownership registries, and cross-border tax enforcement.
- Subnational revenue generation: Strengthening local government revenue systems (property taxes, user fees, licensing) to fund decentralized service delivery.
Market & Policy Impact
- IMF estimates show low-income countries could increase tax-to-GDP ratios by 2-4 percentage points through combined administration and policy reform adding $100-200 billion annually in aggregate.
- Rwanda’s sustained tax-to-GDP improvement from 9% in 2000 to over 15% by 2020 is among Africa’s strongest DRM success stories, driven by Revenue Authority modernization.
- The Global Forum on Transparency and Exchange of Information for Tax Purposes has enabled automatic exchange of financial account information between 120+ jurisdictions, improving offshore enforcement.
- GFI (Global Financial Integrity) estimates illicit financial flows from developing countries at $1-1.8 trillion annually exceeding total ODA and FDI inflows to low-income countries combined.
- The OECD’s BEPS Inclusive Framework, with 140+ country members, has begun redistributing taxing rights over multinational profits toward market jurisdictions, with implications for digital economy taxation.
Modern Case Study: Rwanda’s Revenue Authority Transformation, 2000-2020
Rwanda’s Rwanda Revenue Authority (RRA), established in 1998 amid post-genocide institutional reconstruction, became one of Sub-Saharan Africa’s most cited DRM success stories over the following two decades. Starting from a tax-to-GDP ratio below 9% in 2000, Rwanda implemented systematic revenue administration reform through three interconnected tracks: technology modernization (introducing integrated tax management systems and e-filing a decade before regional peers), organizational professionalization (competitive civil service salaries, performance management, and anti-corruption enforcement within the authority), and taxpayer service improvement (reducing compliance costs through simplified filing and dispute resolution). By 2020, Rwanda’s tax-to-GDP ratio had reached approximately 15.6% nearly double its post-genocide starting point and among the highest in East Africa. The RRA’s model attracted study missions from over 40 African revenue authorities. Crucially, the reforms were domestically designed and politically driven: President Kagame made revenue mobilization a personal priority, providing political cover for enforcement actions against well-connected taxpayers that typically undermine reform in other contexts.
