Introduction

On July 17, 2024, President Bola Ahmed Tinubu sent an executive bill to the Nigerian Senate, proposing an amendment to the Finance Act 2023 via the Finance Bill 2024. This bill introduces a one-time windfall tax of 50% on the realized foreign exchange profits derived by banks during the 2023 financial year. The tax, as proposed, is intended to fund capital infrastructure development, improve access to education and healthcare, and support other public welfare initiatives.

The rationale behind the windfall tax stems from the significant profits banks have earned from foreign exchange transactions, particularly due to excessive currency devaluation and market fluctuations. Factors such as foreign exchange rate unification, fluctuating oil prices, and rising interest rates have contributed to these profits. In contrast, many businesses, especially multinationals, have faced significant losses. Yet, Nigerian banks are estimated to have made extraordinary profits of ₦4.4 trillion in 2023 and another ₦2.03 trillion in the first quarter of 2024, with projections indicating that their total profits could exceed ₦8.2 trillion in 2024. A large portion of these profits are tied to foreign exchange gains from the appreciation of foreign currency reserves relative to the Naira.

This article examines the proposed windfall tax on banks’ foreign exchange gains and its broader economic implications.

Understanding Windfall Taxes

Windfall taxes are special, one-off taxes imposed on companies that have made unusually high profits due to favorable market conditions rather than their operational efforts. These taxes are designed to capture “unearned” or “extraordinary” profits, which are then redistributed to fund public services or address economic imbalances. Governments employ windfall taxes to ensure wealth redistribution, particularly in sectors benefiting disproportionately from market conditions while the general population faces economic challenges.

In Nigeria, the proposed windfall tax targets excess profits from foreign exchange transactions, particularly those stemming from government policies on the Naira. The bill initially set the windfall tax rate at 50%, but after Senate review, the rate was increased to 70% on realized foreign exchange profits from June 2023, when exchange rate unification began, until December 2025. This tax will be administered by the Federal Inland Revenue Service (FIRS), and taxpayers may opt for installment payments if they agree to a deferred payment plan with the FIRS by December 2024.

Economic Objectives of the Windfall Tax

Since May 29, 2023, the Nigerian government has introduced reforms aimed at reshaping the economy and attracting foreign investors. These include the removal of fuel and electricity subsidies, exchange rate unification, and significant interest rate hikes to combat inflation. While these measures are meant to address Nigeria’s economic challenges, they have exacerbated the financial strain on businesses and individuals, leading to reduced liquidity and declining investor confidence.

Faced with a budget deficit of 32% and declining oil revenues, the government is looking for innovative ways to generate revenue. The windfall tax offers an opportunity to raise funds without directly increasing the tax burden on other sectors. It is estimated that the windfall tax could generate as much as 0.3% of the 2024 GDP. Additionally, the tax could promote wealth redistribution, ensuring that the extraordinary profits banks gained from favorable financial policies are used to finance public infrastructure and reduce income inequality.

Challenges and Controversies

Despite its potential benefits, the proposed windfall tax poses significant challenges. One of the main concerns is that imposing such a tax on the banking sector could make Nigeria less attractive to foreign investors. The tax may be seen as unpredictable and punitive, deterring foreign direct investment (FDI) and capital inflows, both of which are vital for economic growth.

Another concern is the timing of the tax. The Central Bank of Nigeria (CBN) recently set new capital requirements for banks, raising the minimum capital for banks with international licenses to ₦500 billion and those with national licenses to ₦200 billion. Introducing a windfall tax during a period of recapitalization could further strain the banking sector and potentially hinder its ability to meet these new requirements.

Moreover, the retrospective nature of the tax, which covers profits from June 2023 to December 2025, contradicts the principles of fairness and certainty in taxation. Nigerian tax policy emphasizes that the tax system should be simple, certain, and predictable. Applying the windfall tax retrospectively undermines these principles, and could face legal challenges for violating the tenets of clarity and fairness.

Global Comparisons

While windfall taxes may seem novel in Nigeria, they have been employed in other jurisdictions. For example, in 2022, the United Kingdom introduced a windfall tax on North Sea oil and gas producers to address the surge in profits caused by rising global energy prices. The proceeds from this tax were used to support households facing rising energy bills. Similarly, in the 1980s, the UK government imposed a windfall tax on banks following significant profits during a period of economic deregulation.

Conclusion and Recommendations

Windfall taxes have been successfully implemented in various countries to generate revenue and redistribute wealth in times of economic hardship. However, the proposed windfall tax on Nigerian banks’ foreign exchange profits faces several challenges. To ensure its success, the government should engage with relevant stakeholders to address concerns, particularly the retrospective nature and high rate of the tax. Reducing the proposed 70% tax rate would prevent the stifling of the banking sector, promote continued investment, and mitigate potential job losses.

Ultimately, the government must balance the need for revenue generation with maintaining a stable and attractive economic environment for investors. Careful implementation of the windfall tax, coupled with stakeholder engagement, will be crucial for minimizing adverse effects on the economy while still achieving its fiscal objectives.
