Nigeria’s public finance architecture is showing signs of strain. In its latest assessment, the World Bank has drawn attention to a structural weakness that goes beyond routine budgetary pressures: the incomplete integration of the country’s Treasury Single Account system and the broader fragility of fiscal reporting.
At the centre of the concern lies a striking figure. More than 5,000 Treasury Single Account sub-accounts remain outside the fully consolidated revenue framework. This fragmentation, the Bank argues, is not merely technical. It raises deeper questions about transparency, coordination, and the credibility of Nigeria’s fiscal position.
A System Designed for Control, Still Struggling with Integration
Nigeria adopted the Treasury Single Account to centralise government revenues and improve oversight. In principle, it is a powerful reform tool, designed to eliminate leakages and enhance cash management.
In practice, however, the system remains only partially realised.
The World Bank notes that treasury operations continue to be fragmented, with incomplete reconciliation between the Government Integrated Financial Management Information System and records held by the Central Bank. The result is a system where multiple accounts operate in parallel, rather than within a unified framework.
This fragmentation has practical consequences. It complicates cash management, delays reporting, and introduces inconsistencies into fiscal data. For policymakers and investors alike, it becomes harder to determine the government’s true financial position.
The Limits of Digital Infrastructure
At the heart of the issue is not the absence of reform, but the incomplete functionality of existing systems.
Key modules within Nigeria’s financial management architecture, including those covering revenue, assets, liabilities, and commitment controls, are not fully operational. Platforms used by major fiscal institutions are not seamlessly linked. Instead, they rely on manual adjustments and post-hoc reconciliation.
This creates a paradox. Nigeria has invested in digital public finance systems, yet the lack of integration means those systems do not deliver their full value.
Coordination challenges further compound the problem. Core institutions such as the Office of the Accountant-General, the Debt Management Office, and the Budget Office operate with systems that do not fully communicate with one another. The consequence is a reporting environment marked by delays and inconsistencies.
Transparency Under Pressure
Beyond operational inefficiencies, the World Bank highlights a more fundamental concern: transparency.
Audited financial statements of the Federal Government have not been published since 2021. Meanwhile, the audit framework itself remains anchored in legislation dating back to 1956. A growing backlog of audits is limiting effective oversight and weakening accountability.
This gap has broader implications. Without timely and credible financial reporting, stakeholders cannot accurately assess government performance. Fiscal projections become less reliable, and confidence in public finance management erodes.
In effect, transparency is not simply a governance issue. It is a macroeconomic one.
Reform Momentum Meets Structural Constraints
The Federal Government has not been idle. Recent reforms led by the Office of the Accountant-General aim to strengthen revenue collection and close leakages.
The introduction of the Federal Treasury e-Receipt as the sole recognised payment instrument, alongside the rollout of a Revenue Optimisation and Assurance Platform, represents a significant attempt to unify billing, automate processes, and integrate key systems.
These measures are designed to improve real-time monitoring, reconciliation, and remittance of government revenues. Officials argue that they will eliminate unauthorised deductions and enhance compliance across Ministries, Departments, and Agencies.
Yet the World Bank’s assessment suggests that implementation remains the critical challenge. Structural weaknesses, institutional fragmentation, and legacy systems continue to limit the effectiveness of these reforms.
Fiscal Pressures and Political Timing
The timing of these concerns is notable. Nigeria is approaching another electoral cycle, and fiscal pressures are expected to intensify in the lead-up to 2027.
The World Bank warns that while higher oil revenues in 2026 may provide some relief, they are unlikely to offset underlying structural challenges. Fiscal discipline, therefore, will depend not just on revenue inflows, but on the integrity of the systems that manage them.
This places renewed emphasis on institutional reform. Without stronger coordination and more reliable reporting, increased revenues may not translate into improved fiscal outcomes.
The Role of Tax and Revenue Reforms
There are, however, signs of progress. The new tax framework introduced in January 2026 is expected to modernise Nigeria’s fiscal architecture. It includes measures to streamline incentives, strengthen administration, and improve intergovernmental coordination.
Over the medium term, these reforms are projected to enhance revenue mobilisation, supported by improved compliance and higher net oil receipts.
Technology is expected to play a central role. The adoption of VAT e-invoicing and broader digitalisation initiatives could improve transparency and reduce leakages across the system.
Additional policy adjustments, including changes in oil revenue remittance structures, are also expected to boost government earnings. Together, these measures could strengthen Nigeria’s revenue base, even as structural challenges persist.
A Persistent Gap with Peers
Despite these efforts, Nigeria’s fiscal position continues to lag behind regional benchmarks. Even with ongoing reforms, the country’s revenue-to-GDP ratio is projected to remain significantly below the Sub-Saharan African average.
This gap underscores the scale of the challenge. Revenue mobilisation is not just about policy changes. It requires sustained improvements in administration, coordination, and institutional capacity.
At the subnational level, further reforms could provide additional gains. Modernising state-level tax systems and improving compliance could help broaden the overall revenue base.
The Credibility Question
Ultimately, the issue raised by the World Bank is one of credibility.
Fiscal systems are not judged solely by their design, but by their execution. A Treasury Single Account that is not fully integrated, a reporting system that relies on manual adjustments, and an audit framework that lags behind modern standards all contribute to uncertainty.
For investors, this uncertainty translates into risk. For policymakers, it limits the effectiveness of fiscal planning. And for citizens, it raises questions about accountability.
BrandiQ Takeaway
Nigeria’s fiscal challenge is no longer just about revenue or expenditure. It is about systems.
The existence of over 5,000 unintegrated Treasury Single Account sub-accounts is not a technical anomaly. It is a signal of deeper institutional fragmentation.
Reforms are underway, and their direction is clear: greater digitalisation, stronger coordination, and improved transparency. But their success will depend on execution.
In the end, fiscal credibility is built not on policy announcements, but on operational integrity. Until Nigeria’s public finance systems function as a coherent whole, the gap between ambition and reality will remain.
