Africa can generate over $469 billion in annual revenue without increasing tax rates if governments improve tax administration and embrace digital systems, the African Development Bank said this week.
The figure, equivalent to roughly ₦770 trillion at current exchange rates, represents money governments are already entitled to collect but currently lose through poor systems, inefficiency, and gaps in enforcement. The AfDB made the case in a new report examining how African nations can unlock revenue without burdening taxpayers or businesses.
Improving tax administration means plugging leaks in collection, reducing the time businesses spend on compliance, and cracking down on evasion. Digitisation—moving from paper-based systems to electronic platforms—makes this possible by creating records that are harder to manipulate and easier to track. Countries that have invested in these upgrades have seen collections rise sharply.
The bank's analysis carries weight because it challenges a common excuse from African governments: that they cannot fund schools, hospitals, and infrastructure because their citizens do not earn enough or cannot afford higher taxes. The AfDB's report suggests the real problem is often how governments collect the money they already have the legal right to take.
This matters urgently. Most African governments spend far less on public services than wealthy nations because their tax bases are smaller and their collection systems leak money. The gap between what they should collect and what they actually do collect—called the "tax gap"—is enormous across the continent.
The AfDB did not say all $469 billion can be found in every country. Some nations have stronger systems than others. But across Africa, the bank found, there is enough waste and inefficiency to generate that sum if governments act. The report urged African leaders to prioritise digital tax systems, train tax staff better, and reduce corruption in revenue agencies.
South Africa, Rwanda, and Kenya have already shown that digital systems work. Rwanda's move to electronic invoicing boosted collections significantly. These examples give other nations a roadmap.
The AfDB's message is straightforward: Africa does not need to squeeze taxpayers harder. It needs to collect what it is owed. Governments that act on this recommendation will see more money flowing into budgets without sparking the anger that comes with tax increases.
