As Nigeria, Others Push For Bold Tax Overhaul To Curb Illicit Financial Flows

A renewed push for sweeping fiscal reforms is gaining momentum across Africa as policymakers, tax administrators, and development experts converge on a common goal: to halt the continent’s massive revenue leakages and build resilient, self-sustaining economies.

At the centre of this drive are Nigeria’s Minister of Finance and Coordinating Minister of the Economy, Wale Edun, and the Executive Chairman of the Nigeria Revenue Service (NRS), Zacch Adedeji, who led calls for bold, coordinated tax reforms at the 5th Session of the African Union Sub-Committee on Tax and Illicit Financial Flows held in Abuja.

The high-level meeting, convened under the African Union’s Specialised Technical Committee on Finance, Monetary Affairs, Economic Planning and Integration, brought together stakeholders from across the continent to address one of Africa’s most persistent economic challenges—illicit financial flows (IFFs).

Opening the session at Transcorp Hotel in Abuja last week, Edun framed the gathering as a critical juncture in Africa’s economic trajectory. He argued that the continent can no longer afford incremental reforms, insisting that the urgency of the moment demands decisive and far-reaching policy actions.

Africa, he noted, is endowed with vast human and natural resources, yet continues to struggle with translating this potential into broad-based prosperity. The missing link, according to him, lies in weak domestic resource mobilisation frameworks and persistent financial leakages.

“The question is no longer whether we must reform, but how urgently and how boldly we are prepared to act,” he said.

Edun stressed that the global economic landscape is shifting rapidly, with evolving trade relations, tightening development finance, and changing geopolitical dynamics.

These shifts, he warned, reinforce the need for African countries to rely more on internal resources rather than uncertain external funding sources.

A central theme of Edun’s address was the need for Africa to reduce its dependence on foreign aid, borrowing, and external investments as primary sources of development financing.

While acknowledging their continued relevance, he described these sources as volatile and often subject to external pressures beyond the continent’s control.

Instead, he advocated a strong pivot toward domestic resource mobilisation, aligning with the African Union’s Agenda 2063 target of financing up to 90 per cent of development needs from within the continent.

Achieving this, he noted, would require systemic reforms—ranging from broadening the tax base and improving compliance to strengthening public financial management and deepening capital markets.

The $88 billion drain

One of the most striking highlights of the discussions was the scale of illicit financial flows. Edun cited estimates showing that Africa loses about $88 billion annually through IFFs—funds that could significantly transform infrastructure, healthcare, education, and industrial development.

He identified key drivers of these losses, including tax evasion, trade mispricing, base erosion, weak institutions, and limited economic diversification.

“These are not abstract challenges,” he emphasised. “They are real constraints on our ability to grow, create jobs, and improve living standards.”

Drawing from Nigeria’s recent experience, Edun outlined a series of reforms implemented under President Bola Tinubu aimed at strengthening fiscal stability and transparency.

These include comprehensive tax reforms to simplify the system and expand the tax base, the removal of fuel subsidies to reduce fiscal distortions, and the unification of exchange rates to improve market efficiency and investor confidence.

He also highlighted the introduction of the National Single Window system to streamline trade processes and curb revenue leakages linked to cross-border transactions.

According to him, these measures are already yielding results, with improved non-oil revenue performance, stronger fiscal buffers, and renewed investor confidence.

In his welcome address, Adedeji reinforced the urgency of tackling illicit financial flows, describing them as a direct threat to Africa’s development aspirations.

He painted a stark picture of the consequences, noting that billions of dollars lost annually to illicit activities represent “lost schools, lost hospitals, and lost opportunities” for millions of Africans.

Dr. Adedeji positioned revenue authorities as central actors in reversing this trend, stressing that effective tax systems do more than generate income—they strengthen governance, enhance transparency, and build trust between citizens and the state.

Under his leadership, the NRS has embarked on an ambitious modernisation programme aimed at transforming Nigeria’s tax administration into a technology-driven, efficient, and transparent system.

Key elements of this reform include the deployment of digital platforms to improve tax compliance, expansion of the tax net, and enhanced data analytics to detect and prevent tax evasion and illicit flows.

Industry observers note that Adedeji has emerged as a key figure in Nigeria’s anti-IFF strategy, championing reforms that align with global best practices while addressing local realities.

His emphasis on data-driven tax administration and international cooperation has strengthened Nigeria’s capacity to track, recover, and prevent illicit financial outflows.

A recurring theme across the sessions was the transnational nature of illicit financial flows, which often exploit regulatory gaps between countries. Adedeji stressed that no single country can effectively tackle the problem in isolation, calling for deeper collaboration among African nations.

He highlighted the importance of platforms such as the AU sub-committee in fostering policy coordination, knowledge sharing, and joint enforcement strategies.

There were not alone. Also contributing to the discussions, Executive Director of Tax Justice Network Africa, Chenai Mukumba, challenged African leaders to move beyond rhetoric to concrete implementation.

She acknowledged the growing consensus around the need for tax reforms and domestic resource mobilisation but warned that progress has been slow due to weak execution. “The real challenge is not in identifying solutions, but in implementing them effectively,” she said.

Mukumba called for clear timelines, measurable targets, and accountability frameworks to ensure that reform commitments translate into tangible outcomes.

She also emphasised the importance of aligning national strategies with continental frameworks to maximise impact.

Digital economy and global tax rules

Mukumba further highlighted the complexities introduced by the digital economy, noting that it presents both opportunities and risks for African tax systems.

She urged governments to develop robust frameworks for taxing digital activities while leveraging technology to improve compliance and enforcement.

In addition, she called for stronger African participation in global tax negotiations, particularly under emerging international frameworks, to ensure that the continent’s interests are adequately represented.

Across all interventions, a clear consensus emerged: Africa’s long-term prosperity hinges on its ability to build strong fiscal institutions, protect its resources, and finance development from within.

This requires not only policy reforms but also investments in digital infrastructure, institutional capacity, and regional cooperation.

It also demands political will—what Edun described as the courage to take difficult decisions and the discipline to sustain them.

As deliberations continue, stakeholders agree that the fight against illicit financial flows is both a national and continental responsibility.

For Nigeria, the leadership of Edun and Adedeji signals a commitment to driving reforms that could serve as a model for other African countries. For the continent, the Abuja meeting represents another step toward a more coordinated and effective response to financial leakages.

The challenge now lies in translating these commitments into action—closing loopholes, strengthening institutions, and ensuring that Africa’s wealth works for its people.

In the words of Edun, the moment demands urgency, cooperation, and resolve. The cost of inaction, as the figures show, is simply too high.
