No Global Taxes: What Happens to International Tax Cooperation?

For nearly a decade, the OECD-led two-pillar framework worked toward a coordinated global approach to taxing large multinational enterprises, including a 15 percent global minimum tax under Pillar Two. Recent developments, including the United States' formal exemption from Pillar Two obligations announced in January 2026, have raised questions about how far this coordination will hold. For Nigerian businesses with foreign shareholders, foreign subsidiaries, or multinational trading partners, understanding this shift matters, even for businesses that are not themselves large multinationals.

How International Tax Cooperation Works

The OECD/G20 Inclusive Framework brought together more than 140 jurisdictions to agree on two broad measures:

• Pillar One, intended to reallocate some taxing rights over large multinational profits to the countries where customers are located, rather than only where the company is formally based.
• Pillar Two, which sets a 15 percent global minimum effective tax rate for large multinational groups, using top-up tax mechanisms to prevent profit shifting to low-tax jurisdictions.

In January 2026, the OECD Inclusive Framework issued a "Side-by-Side" package that effectively exempts US-parented multinational groups from the Income Inclusion Rule and Undertaxed Profits Rule under Pillar Two, following the earlier US withdrawal from the broader global tax agreement. This does not end Pillar Two globally, but it signals that full multilateral alignment is no longer guaranteed, and that individual countries, including Nigeria, will continue to shape their own rules around, rather than strictly within, the original framework.

Step-by-Step: What Nigerian Businesses Should Do

1. Determine if you fall within scope. Pillar Two rules generally apply to multinational groups with consolidated annual revenue above €750 million. Most Nigerian SMEs fall outside this threshold, but subsidiaries of qualifying foreign groups should check their group's reporting obligations.
2. Review your group structure. If your business has a foreign parent, subsidiary, or significant related-party transactions, confirm how recent global tax developments affect your group's overall tax position, not just Nigeria's domestic filing.
3. Track Nigeria's own tax reform position. The Nigeria Tax Act, 2025, restructured Nigeria's domestic tax system independently of Pillar Two negotiations, and Nigerian filing obligations continue regardless of what happens at the OECD level.
4. Maintain transfer pricing documentation. Where cross-border related-party transactions exist, proper transfer pricing records remain essential, as Nigeria's domestic transfer pricing rules operate separately from the global minimum tax debate.
5. Seek professional guidance on group-level exposure. A professional firm can help determine whether shifting global rules create any additional reporting requirement for the Nigerian entity.

Why This Matters to Nigerian Taxpayers

Even where a Nigerian business is not itself subject to Pillar Two, weaker international tax coordination generally means more, not fewer, country-specific rules to track, as jurisdictions increasingly protect their own tax base independently. This raises the importance of accurate domestic compliance with the NRS, since Nigeria's own revenue mobilization targets, set at N40.7 trillion for 2026, depend on strong domestic collection regardless of global developments.

Tax Implications

• Nigerian domestic tax obligations under the Nigeria Tax Act and Nigeria Tax Administration Act are unaffected by whether Pillar Two is implemented globally; local filing and payment obligations remain in force.
• Businesses with foreign group affiliations should confirm whether their parent entity's home country has adopted Pillar Two rules and, if so, whether this creates any indirect reporting obligation.
• Transfer pricing compliance remains a distinct and ongoing obligation for Nigerian entities with related-party cross-border transactions, separate from the global minimum tax debate.

Why Every Business Should Comply with Tax Regulation

Regardless of how international tax cooperation evolves, Nigeria's domestic tax administration continues to strengthen its enforcement capacity, including consolidated penalties for late or incorrect filing and a formal Tax Ombuds office for dispute resolution. A business that stays compliant domestically is better protected from exposure, irrespective of how global negotiations unfold.

The Advantage of Professional Guidance

Global tax developments move quickly, and a business owner cannot reasonably be expected to track OECD negotiations alongside daily operations. A professional consulting firm helps by:

• Assessing whether group-level global tax developments create any obligation for the Nigerian entity.
• Keeping transfer pricing documentation current and defensible.
• Ensuring domestic NRS filings remain accurate regardless of international developments.

Frequently Asked Questions

Does the US exemption from Pillar Two affect Nigerian tax law directly? No. Nigeria's domestic tax obligations under the Nigeria Tax Act and Nigeria Tax Administration Act remain in force regardless of international developments around Pillar Two.

Which businesses are affected by Pillar Two? Generally, multinational groups with consolidated annual revenue above €750 million. Most Nigerian SMEs are outside this scope, though subsidiaries of large foreign groups should confirm their position.

Should a Nigerian business with a foreign parent be concerned? It is worth a professional review, particularly regarding transfer pricing documentation and any indirect reporting flowing from the parent company's obligations abroad.
