Finance Experts Say Nigeria’s Tax Policy Could Threaten GDP Growth and Investor Confidence

Economic analysts have raised concerns that Nigeria’s proposed tax reforms could hinder the country’s target of achieving double-digit growth and becoming a trillion-dollar economy by 2030. The caution comes ahead of the planned implementation of the new tax policy in January 2026.

Tax expert Taiwo Oyedele has been at the forefront of promoting the reforms, which aim to increase Nigeria’s tax-to-GDP ratio from 9 percent to 18 percent. However, many economists believe the policy could dampen economic expansion rather than stimulate it.

Concerns Over Higher Tax Burden

Analysts argue that while the goal of widening the tax net is commendable, raising taxes at a time when Nigerians are struggling with inflation and reduced purchasing power could weaken consumer demand. The current administration hopes to use higher tax revenue to boost public spending, but experts warn that such measures may stifle investment and slow job creation.

Mr. Oyedele has explained that the reforms will be progressive, ensuring that the wealthy contribute more while sparing low-income earners. He noted that the initiative will target previously untaxed sectors, including parts of the informal economy.

However, critics fear that taxing the informal sector could further burden ordinary Nigerians who already face high living costs. Many families depend on small-scale businesses for survival, and additional taxes could make it harder for them to afford essential needs like education and healthcare.

Economic History Offers a Warning

Observers have drawn lessons from global economic history, pointing out that excessive taxation has often led to slower growth. In the past, both the United States and the United Kingdom experienced economic stagnation after raising taxes post-World War II. Growth only returned when leaders like Ronald Reagan and Margaret Thatcher introduced tax cuts.

Countries such as Ireland also achieved rapid economic progress by reducing corporate taxes to attract investors. Many fear that Nigeria’s decision to raise taxes could produce the opposite effect, discouraging foreign direct investment and limiting private sector growth.

Impact on Investors and Businesses

Investors are reportedly cautious about the proposed 18 percent tax-to-GDP ratio. High taxes on corporate profits and value-added goods could reduce profitability and discourage expansion. For example, leading industrialists like Aliko Dangote have previously noted that a large share of their profits already goes to the government.

Business leaders argue that lowering taxes, rather than raising them, would encourage investment and lead to higher revenue over time. According to them, increased business activity would generate more taxable income naturally, without burdening citizens or discouraging entrepreneurship.

Questions Over Government Accountability

Economic experts also question whether additional tax revenue will be managed efficiently. Many Nigerians remain skeptical about government transparency and spending discipline. Analysts argue that raising taxes without first improving governance and accountability could lead to waste rather than development.

Quoting the Biblical principle from Luke 16:10 — “He who is dishonest in little will be dishonest in much” — some commentators believe the government must first prove itself trustworthy with existing resources before demanding more from taxpayers.

Effects on Consumption and Inflation

The proposed tax increase is expected to affect purchasing power across all income groups. Although the government has stated that individuals earning below ₦800,000 annually will be exempt, experts point out that inflation has already eroded the real value of wages. With the minimum wage at ₦70,000 per month and consumer prices rising sharply, many Nigerians are already struggling to meet basic needs.

Economists warn that higher taxes could further reduce household consumption, slowing business activity and overall GDP growth. Combined with the rising cost of doing business, including electricity tariffs and logistics expenses, the private sector could face additional strain.

Alternative Path to Economic Growth

Experts have urged the federal government to consider policies that encourage productivity and investment rather than relying heavily on taxation. They recommend improving infrastructure, simplifying business registration, and offering tax incentives to attract investors.

Some also advocate for a gradual approach — focusing first on expanding economic activities and reducing wasteful spending before implementing aggressive tax targets. They argue that sustainable growth can only occur when businesses thrive, leading to natural increases in government revenue.

Nigeria’s Path to a Trillion-Dollar Economy

For Nigeria to achieve its trillion-dollar GDP ambition by 2030, the economy would need to grow by at least 20 percent annually — a target experts say may be unrealistic under heavy taxation. Many fear that the new tax regime could widen inequality, concentrating wealth among political elites while pushing more citizens into poverty.

Countries with higher tax-to-GDP ratios, such as South Africa, have also struggled with inequality and sluggish growth. Analysts warn that Nigeria could face similar challenges if the reforms are implemented without corresponding measures to boost productivity and ensure fair distribution of wealth.

The Way Forward

While the government insists the reforms are designed to stabilize public finances, economic observers believe a more balanced approach is necessary. They suggest prioritizing investor confidence, lowering tax rates for small and medium-sized enterprises, and streamlining revenue collection to prevent duplication and corruption.

Encouraging private investment, they say, is a proven path to job creation and higher revenue. Businesses that grow and thrive will naturally generate more taxes without government coercion.

Ultimately, experts conclude that increasing taxes without first achieving strong economic growth could backfire. For Nigeria to reach its trillion-dollar dream, the focus should be on expanding opportunities, improving governance, and supporting an environment where both local and foreign investors can flourish.
