Who Pays When the Aid Runs Out? Africa’s New Battle for Trust
Foreign aid is shrinking, but Africa’s bills are not.
Schools must still open. Hospitals must still function. Roads must still be built, public employees must still be paid and mounting debts must still be serviced. The difference is that African governments can no longer assume foreign donors will help cover the cost.
Increasingly, governments must ask their own citizens to fill the gap. That is where the real political struggle begins.
For decades, foreign aid provided many African governments with a quiet safety net. It covered budgetary shortfalls, sustained social programmes and helped finance visible projects. As that support retreats, governments face a more difficult question: why should citizens pay more to states they do not trust?
That safety net is now fraying. Early estimates indicate that bilateral aid to sub-Saharan Africa fell by approximately 26 per cent in 2025, while multilateral support is also under pressure. As recent International Monetary Fund analysis makes clear, these cuts are broad, driven by donor decisions and hitting countries with limited room to adjust.
Governments therefore face an unforgiving set of choices. They can raise revenue, reprioritise spending, borrow more or leave lost aid unreplaced, allowing programmes to lapse. None of these options is politically painless. The real issue is not simply how states will replace lost aid. It is whether they can persuade their citizens that the state deserves more of their money.
Africa Is Not Poor in Resources
Africa’s financing challenge is enormous, but so is the potential to mobilise resources more effectively.
The African Development Bank estimates that the continent could unlock up to $1.43 trillion annually through a broad package of reforms. These include stronger revenue collection, more efficient public investment, reduced financial leakages, deeper capital markets, expanded public-private partnerships and better use of natural capital.
This is potential financing, rather than a pool of money governments can immediately recover. Nevertheless, the scale of the opportunity is striking.
The bank identifies approximately $469 billion in potential additional annual revenue from stronger tax and non-tax mobilisation, alongside roughly $299 billion in potential savings from improved public investment efficiency. Its estimated public investment efficiency gap is 41 per cent: spending that is wasted or fails to translate into productive capital.
Tax collection across Africa averages approximately 16 per cent of GDP, according to the Institute for Security Studies. Narrow tax bases, large informal economies, exemptions and fragmented administrative systems all limit what governments collect.
Illicit financial flows create another substantial drain. Research highlighted by Brookings cites a UN estimate that Africa loses approximately $90 billion annually through such flows.
Too much economic activity escapes the tax system, while too much public spending fails to produce meaningful results. As foreign assistance becomes less dependable, improving both collection and delivery becomes increasingly urgent.
No Trust, No Tax Bargain
Taxation is not merely an administrative procedure. It is one of the most direct encounters between citizens and the state.
A government demands part of what people earn. In return, citizens expect security, infrastructure, education, healthcare and equal treatment under the law. When that exchange works, taxation can strengthen the state. When it does not, taxation feels like organised extraction.
Citizens notice when salaried workers are taxed automatically while politically connected companies receive generous exemptions. They notice when small traders face aggressive enforcement while powerful individuals move wealth across borders. They notice when a new levy is introduced but the local school remains overcrowded, the road remains broken and the clinic remains understaffed. They also notice when politicians demanding sacrifice appear to make none themselves.
Public trust is therefore a central constraint, alongside administrative capacity. A government can digitise payments, automate collection and build increasingly sophisticated databases. But if citizens believe the system is corrupt or selective, those improvements alone will not establish a fair fiscal bargain.
When Tax Policy Ignites the Streets
When citizens conclude that the fiscal bargain is fundamentally unfair, discontent can quickly move from tax offices to the streets.
Even countries with comparatively developed revenue systems can face fierce resistance to new taxes. Fragile or conflict-affected states confront an additional problem: in many areas, the state lacks the administrative reach required to collect revenue or deliver services.
Large informal economies create another trap. Push formalisation too aggressively and governments risk damaging fragile livelihoods. Ignore it and the tax burden remains concentrated on the same narrow group of compliant workers and businesses.
Meanwhile, influential groups have incentives to preserve exemptions and privileges. Tackling cross-border profit shifting requires technical expertise and international cooperation. Meaningful institutional reform takes time, while governments facing immediate financing gaps need revenue now.
Debt intensifies these pressures. When debt servicing absorbs scarce public resources, less remains for services and investment. Citizens may then be asked to pay more without seeing corresponding improvements in daily life.
Kenya’s youth-led anti-tax protests demonstrate how quickly fiscal policy can become a national political crisis. Opposition to new taxes can become inseparable from wider grievances about governance, living costs and public accountability.
A state cannot indefinitely demand greater sacrifice while delivering disappointing services and protecting privileged insiders.
Collect Better, Not Simply More
Avoiding that cycle does not necessarily require another round of broad tax increases. African governments have considerable room to collect revenue more intelligently and fairly.
The African Development Bank’s Chief Economist has advocated stronger revenue administration, better compliance and improved economic governance as part of a comprehensive financing strategy.
The order of reform matters. Governments should demonstrate that the powerful will be pursued before demanding more from those who already comply. Additional revenue should also produce visible improvements in public goods. Citizens should be able to see how stronger collection translates into functioning schools, better roads and reliable healthcare.
Institutional reform is equally important. Political interference in audits should be reduced. Tax expenditures and corporate exemptions should be published and regularly reviewed. Regional cooperation should make it harder to hide wealth or shift profits across borders.
Formalisation must also offer benefits. If entering the formal economy brings only new taxes, paperwork and inspections, businesses will understandably resist. It should also provide legal protection, access to finance and simpler regulations. Formality must become an opportunity, not a punishment.
The potential is substantial, although the gains will take time. ISS African Futures scenario modelling suggests that improvements in government effectiveness and economic formalisation could generate approximately $37.7 billion in additional annual revenue by 2034, compared with projected annual aid losses of about $27.5 billion.
That is a modelled scenario, not a guaranteed outcome. But it illustrates why stronger institutions and a broader formal economy offer a more promising response than simply increasing tax rates.
The State After Aid
These reforms are achievable. The harder question is whether political leaders are willing to implement them consistently.
Domestic resource mobilisation deserves a central place in Africa’s development strategy. But frameworks and declarations will achieve little unless governments confront the exemptions, discretion and patronage that keep existing systems unfair.
African governments cannot safely assume that aid will return to previous levels. They must prepare for outside assistance that is less generous and less predictable.
This could produce stagnation, deteriorating services and deeper public anger. But it could also encourage a long-overdue transformation. Greater reliance on domestic revenue creates an opportunity to strengthen the relationship between citizens and the governments they finance. Whether that opportunity produces greater accountability depends on political institutions and public scrutiny.
Governments that respond by squeezing the same workers and small businesses will intensify resentment. Governments that broaden the tax base, confront elite privilege and turn additional revenue into visible public services could build something far more valuable than another donor-funded project: a credible state.
As aid retreats, African governments will be judged not only by how much they collect, but by what they deliver. The challenge is no longer simply to replace foreign assistance. It is to build states worthy of their citizens’ trust, and their taxes.
