Aluko & Oyebode Flags Expanded Tax Disclosure Regime Under Nigeria’s New Tax Framework

By Olumide Johnson

Aluko & Oyebode, a member of the African Legal Network, has highlighted the implications of Nigeria’s emerging mandatory disclosure framework for tax planning arrangements under Section 30 of the Nigeria Tax Administration Act, signalling a broader shift toward stricter tax transparency, early compliance monitoring and anti-avoidance enforcement within the Federal Government’s evolving fiscal reform architecture.

The advisory note, issued through the firm’s ‘Tax Thursday’ series, stated that certain transactions and arrangements designed primarily to obtain tax advantages may now require mandatory disclosure to relevant tax authorities, even without a formal request from regulators.

According to the guidance, parties entering or planning to enter such arrangements are required to disclose them where the principal objective involves obtaining tax benefits including reliefs, repayment advantages, tax deferrals, reduction of assessments or avoidance of tax obligations.

The framework empowers tax authorities to issue regulations defining disclosure thresholds, filing timelines, reporting procedures and penalties for non-disclosure, incomplete disclosure or delayed submission.

The development comes amid broader efforts by the administration of President Bola Ahmed Tinubu to strengthen domestic revenue mobilisation, improve tax administration transparency and widen the formal compliance net across the economy.

DECISION HIGHLIGHT

The core policy shift is the introduction of a mandatory disclosure regime requiring proactive reporting of tax planning schemes considered capable of delivering tax advantages.

The regime effectively moves Nigerian tax administration from largely reactive enforcement toward anticipatory compliance surveillance.

It also increases regulatory visibility into aggressive tax structuring before revenue leakage fully materialises.

DECISION MEMO

The emerging disclosure framework signals a deeper transformation within Nigeria’s fiscal governance model.

Historically, Nigerian tax administration has relied heavily on post-transaction audits, investigations and enforcement actions after potential tax avoidance had already occurred. The new disclosure regime changes that sequence by giving tax authorities earlier access to transaction structures considered capable of eroding the tax base.

The framework therefore reflects a broader institutional migration toward preventive tax administration rather than retrospective enforcement.

For regulators, the approach potentially improves risk detection, strengthens audit intelligence and enhances the ability of authorities to identify sophisticated tax planning arrangements across sectors.

For businesses, however, the implications are more strategic.

Tax planning structures previously treated as conventional optimisation mechanisms may now face elevated disclosure obligations, increased regulatory scrutiny and wider interpretative exposure regarding what constitutes a “tax advantage.”

The breadth of the definitions is particularly significant.

The framework extends beyond outright tax avoidance to include deferred tax payments, reduced assessments, accelerated repayments and avoidance of deduction obligations. That expansive scope potentially broadens the compliance burden for corporates, investment vehicles, multinational structures and advisory firms operating across complex transaction environments.

The policy direction also aligns with broader global trends driven by the Organisation for Economic Co-operation and Development’s Base Erosion and Profit Shifting standards, where jurisdictions increasingly require early disclosure of aggressive tax arrangements.

Within Nigeria’s current fiscal environment, the framework reflects growing pressure on revenue authorities to strengthen non-oil revenue generation amid debt servicing pressures, subsidy reforms and widening fiscal constraints.

The disclosure regime therefore represents not merely a compliance adjustment, but part of a wider restructuring of Nigeria’s tax governance architecture toward data-driven enforcement, transparency and predictive compliance supervision.

DATA BOX

• Legal Basis: Section 30, Nigeria Tax Administration Act
• Core Requirement: Mandatory disclosure of tax planning arrangements designed to obtain tax advantages
• Disclosure Trigger: Main objective of transaction is tax benefit acquisition
• Tax Advantages Defined To Include:
  • Relief or increased tax relief
  • Repayment or increased repayment of tax
  • Reduction or avoidance of assessment
  • Deferral of tax payment
  • Advancement of tax repayment
  • Avoidance of obligation to deduct or account for tax
• Regulatory Powers Granted To Tax Authorities:
  • Define disclosure information requirements
  • Determine filing timelines
  • Prescribe submission procedures
  • Enforce penalties for non-disclosure or delayed disclosure
• Policy Objective: Early visibility into tax avoidance schemes and enhanced transparency

WHO WINS / WHO LOSES

Potential Winners:

• Nigeria Revenue Service and tax authorities through improved compliance intelligence
• Government revenue administration through earlier detection of tax leakage risks
• Regulatory technology and tax advisory compliance providers

Potential Losers:

• Aggressive tax planning structures reliant on opacity
• Businesses with weak compliance documentation systems
• Complex cross-border structures exposed to expanded reporting scrutiny

POLICY SIGNALS

The framework signals intensifying government focus on domestic revenue mobilisation and institutional tax enforcement efficiency.

It also suggests increasing convergence between Nigeria’s tax governance model and international anti-base erosion standards.

The policy direction further indicates that tax transparency is becoming a central pillar within the administration’s wider fiscal consolidation strategy.

INVESTOR SIGNAL

For institutional investors, the framework improves long-term visibility regarding Nigeria’s evolving tax compliance environment, although it simultaneously raises disclosure expectations and transaction scrutiny.

The regime may strengthen perceptions of regulatory seriousness and fiscal discipline, particularly among investors prioritising governance transparency and compliance certainty.

However, implementation consistency and interpretative clarity will remain critical to maintaining investor confidence.

RISK RADAR

• Broad interpretation of “tax advantage” could trigger compliance disputes
• Increased reporting obligations may raise transaction costs
• Potential regulatory overlap between tax authorities and sector regulators
• Risk of inconsistent enforcement or discretionary interpretation
• Compliance readiness gaps among medium-sized enterprises
• Possibility of delayed transactions pending disclosure assessments
