Nigeria overhauls its tax code for the first time in decades just as US aid cuts end its HIV and TB programs
Nigeria is Africa’s largest economy, with immense resource wealth and equally significant development obstacles. In 2025 alone, it passed its most significant tax overhaul in a generation, absorbed one of the sharpest aid shocks of any country on this list, and continued grappling with the same oil-driven governance problems that have shaped its economy for decades. This article covers aid, tax, climate, and trade, the same four threads RYB tracks across every country page.
A Historic Aid Collapse
The US halted foreign aid funding to Nigeria within days of the Trump administration taking office in January 2025, placing thousands of USAID staff on compulsory leave and terminating programmes across health, water, and governance. USAID formally closed on July 1, 2025, with disbursements globally falling from $68 billion in 2024 to $32 billion in 2025.
The human cost in Nigeria specifically has been severe. HIV treatment programmes were curtailed or terminated, alongside tuberculosis case management support and family planning and reproductive health services that had operated for years. The E-WASH programme, which brought clean water and sanitation access to millions across six Nigerian states, lost its funding entirely.
Nigerian civil society voices have been blunt about the compounding effect. Solape Sonuga, director of Nigeria’s Legislative Mentorship Initiative, has warned that aid cuts across the region worsen gender inequities specifically, disrupting gender-based violence response services and maternal healthcare in ways that reverse years of progress within months.
Some Nigerian officials have reframed the shock as a forcing function. The government has launched a transition committee to plan for continuity without US funding, with some stakeholders arguing publicly that the cut serves as “a wake-up call” for Nigeria to build more self-reliant financing, a theme that connects directly to the tax reforms described below.
A Landmark Tax Reform, Finally Arriving
On June 26, 2025, President Bola Tinubu signed four Tax Reform Acts into law, the most comprehensive overhaul of Nigeria’s tax system in decades, effective January 1, 2026. The Nigeria Tax Act consolidates and replaces six separate laws, including the Companies Income Tax Act, Personal Income Tax Act, Petroleum Profits Tax Act, and VAT Act, into a single, modernised framework.
Several changes directly target Nigeria’s historically narrow tax base, covered elsewhere on RYB’s Tax Havens page, where Nigeria’s estimated $15 billion in annual losses to tax avoidance and illicit financial flows exceeds the country’s entire health budget. The reform raises the small-company exemption threshold from ₦25 million to ₦100 million in annual turnover, while introducing a new 4% Development Levy on larger companies, consolidating four previously separate levies into one.
The reform also closes a specific, longstanding loophole: capital gains on shares sold through offshore intermediary holding companies will now trigger Nigerian capital gains tax, directly targeting the kind of profit-shifting structures that have long allowed wealth to exit Nigeria’s tax net. VAT input recovery was also expanded to align with international norms, and a new Economic Development Tax Incentive replaces the old Pioneer Status regime with stricter, credit-based conditions tied to actual investment size.
A new 5% fossil fuel surcharge, aimed at funding Nigeria’s clean energy transition, sits directly alongside continued reliance on petroleum revenue, the same tension RYB has documented in other resource-dependent economies. Whether the Federal Inland Revenue Service, now reorganised as the autonomous Nigeria Revenue Service, can enforce these reforms effectively will determine whether they close Nigeria’s tax gap in practice, not just on paper.
Climate: The Niger Delta’s Unresolved Cost
Environmental degradation in the Niger Delta remains one of Nigeria’s most persistent, least-resolved development problems. Decades of oil spills have destroyed traditional fishing and farming livelihoods, while gas flaring continues to waste potential energy resources and contribute meaningfully to Nigeria’s greenhouse gas emissions.
The new fossil fuel surcharge represents Nigeria’s clearest recent policy signal on climate, though its 5% rate on fuel, with exemptions for kerosene and cleaner-burning fuels like LPG and CNG, remains a modest instrument relative to the scale of the country’s oil-dependent economy and its persistent flaring problem.
Trade: Opening Up to Washington, Unevenly
Nigeria moved to ease trade tension with the US directly in 2026. Its new Fiscal Policy Measures and Tariff Amendments, announced April 1, eliminate or phase out import adjustment taxes on nearly all agricultural imports from the US, including a cut on US wheat tariffs from 15% to 0%, alongside reductions on live animals, animal feed, ethanol, and rice.
This move comes as Nigeria’s own fiscal position strains under falling oil prices and the effects of the wider 2025 US tariff regime, part of the pressure the Africa Report has described as putting Nigeria’s ₦36 billion budget “under siege.” Nigeria was not singled out for the steep bespoke tariffs some countries faced, but remains subject to the broader baseline rate applied across most US trading partners.
This connects to a wider regional pattern. Elsewhere in Africa, South Africa’s auto sector has faced a 25% US tariff, and Zimbabwe has offered zero tariffs in a bid for sanctions relief, evidence that 2025-26’s tariff shifts are reshaping trade calculations across the continent, not just for Nigeria alone.
What Nigeria Still Contributes
Nigeria’s fiscal reform ambition extends beyond tax. President Tinubu’s 2023 removal of longstanding fuel subsidies, though painful in the short term, addressed a distortion that had drained government resources for years, and the accompanying disinflation story, documented on RYB’s Inflation page, saw Nigeria’s inflation fall from 118% at the end of 2024 to 31.5% by the end of 2025, one of the sharpest turnarounds anywhere in the world.
Nigeria’s cash transfer and social safety net programmes, though still limited in coverage, represent a genuine policy tool for cushioning reform’s impact on the poorest households, a model other reforming economies in the region continue to study.
How This Connects to the SDGs
The collapse of US-funded HIV and tuberculosis programmes threatens SDG 3, good health and well-being, directly and immediately, reversing gains built over two decades of USAID investment. The 2025 tax reforms offer a genuine, structural response to SDG 17, global partnerships, and the domestic resource mobilisation goal that underpins it, addressing a problem RYB has documented as costing Nigeria more than its aid receipts.
Persistent oil spills and gas flaring in the Niger Delta undermine SDG 13, climate action, and SDG 15, life on land, while the fossil fuel surcharge represents an early, modest step in the opposite direction. Nigeria’s fuel subsidy removal and disinflation connect to SDG 1, ending poverty, in a genuinely two-sided way: painful in the short term, but potentially foundational for longer-term fiscal sustainability.
Looking Forward
Nigeria’s 2026 tax reforms represent a genuine test of implementation capacity, not just political will. Whether the newly autonomous Nigeria Revenue Service can enforce the new rules, particularly around offshore share transfers and the expanded VAT base, will determine whether Nigeria’s tax-to-GDP ratio actually rises or whether enforcement gaps persist as before.
The scale of the US aid withdrawal leaves a gap no single policy reform can fill quickly. Whether Nigeria’s own resource mobilisation, and continued disinflation, can offset the loss of HIV, tuberculosis, and water and sanitation funding will be one of the clearest tests of self-reliant development financing anywhere in the world this decade.
RYB will track how Nigeria’s tax reforms perform in practice once they take effect in January 2026, whether Niger Delta environmental remediation gains any real traction, and how Nigeria’s trade relationship with Washington evolves alongside its regional peers. This page will be updated as new data and policy decisions emerge.

Background
In ancient and pre-colonial times, the area of present-day Nigeria was occupied by a great diversity of ethnic groups with very different languages and traditions. British influence and control over what would become Nigeria and Africa’s most populous country grew through the 19th century. A series of constitutions after World War II granted Nigeria greater autonomy. After independence in 1960, politics were marked by coups and mostly military rule, until the death of a military head of state in 1998 allowed for a political transition. In 1999, a new constitution was adopted and a peaceful transition to civilian government was completed. The government continues to face the daunting task of institutionalizing democracy and reforming a petroleum-based economy, whose revenues have been squandered through decades of corruption and mismanagement. Nigeria continues to experience longstanding ethnic and religious tensions, though it has sustained its longest period of civilian rule since independence, including the country’s first ever civilian-to-civilian transfer of power between opposing parties in 2015.
That petroleum-based economy, and the decades of squandered revenue described above, is precisely what Nigeria’s 2025 tax reforms and fossil fuel surcharge are now attempting to address, even as the country absorbs one of the steepest foreign aid shocks of any nation on this list.
