For much of the last decade, multinational tax planning operated on a simple premise: profit could be structured to land wherever the rate was lowest, provided the paperwork held. Nigeria’s 2026 reform does not merely tighten that premise — it dismantles the floor beneath it. Under the Nigeria Tax Act, large corporations and multinational enterprises operating in the country are now subject to a minimum effective tax rate of 15%, brought into alignment with the OECD’s global minimum tax framework. A structure that once delivered a materially lower effective rate through treaty positioning or profit allocation no longer delivers that outcome, regardless of how cleanly it was built.

The Broader Redefinition
The 15% floor does not stand alone. It arrives alongside a substantially widened definition of what creates a taxable presence in Nigeria in the first place. The law now recognises a foreign company’s Significant Economic Presence — activity conducted through a digital platform, generating income from Nigerian users, without any physical footprint whatsoever — as sufficient grounds for taxation. Separately, the definition of Permanent Establishment has been broadened to capture foreign companies with a place of management in Nigeria, adopting language consistent with standard double taxation treaty conventions.
Taken together, these changes mean two things for multinational groups. First, entities that previously sat comfortably outside Nigeria’s taxable net — because they had no office, no factory, no visible presence — may now find themselves squarely inside it, purely on the strength of digital revenue or management activity. Second, once a taxable presence is established, the profit attributed to it cannot be engineered below the 15% floor through the margin-shifting techniques that once worked.
The Minimum Profit Margin Provision
A related but distinct mechanism deserves attention: nonresident companies with a Permanent Establishment or Significant Economic Presence in Nigeria are now subject to a minimum profit margin requirement, meaning the profit attributed to the Nigerian operation cannot fall below that of the nonresident parent as a whole. This closes a specific and previously effective technique — allocating disproportionately thin margins to the Nigerian entity while the wider group’s profitability remained materially higher elsewhere.
What Sophisticated Groups Should Be Reviewing Now
- Transfer pricing documentation. Master and local files need to withstand scrutiny under a regime that assumes profit-shifting as the default hypothesis, not the exception.
- Digital revenue attribution. Any group generating meaningful Nigerian revenue through platforms, without a formal local entity, should assess Significant Economic Presence exposure directly rather than assuming physical absence is sufficient protection.
- Group effective tax rate modelling. The 15% floor should be built into consolidated tax provisioning now, not discovered at year-end reconciliation.
- Contractual tax representations. Template agreements — supply agreements, service agreements, SPAs — drafted under the prior regime may contain tax warranties that no longer reflect current exposure.
A Note on Timing
Nigeria’s move mirrors a global direction of travel, not an isolated policy choice. Groups already managing minimum-tax compliance in other OECD-aligned jurisdictions will find the underlying logic familiar, even where Nigeria’s specific mechanics diverge. That familiarity is useful, but it is not a substitute for a Nigeria-specific review — the SEP provisions in particular have no precise analogue in most other jurisdictions’ minimum tax regimes.
At Reditto Centrale, we work with multinational and internationally-linked businesses to translate this kind of structural reform into a concrete compliance position — one that holds up under the data-matching capabilities the Nigeria Revenue Service now has at its disposal. For groups still operating on a pre-2026 assessment of their Nigerian exposure, that assessment is now materially out of date.
