Nigeria's Finance Bill 2027 Review: The Six-Week Subcommittee Born From a Tax Filing Crisis

Coverage of this subcommittee's inauguration has largely framed it as a scheduled, healthy piece of continuous-improvement housekeeping, Minister Oyedele himself described it that way, and there is truth in that framing. But treating it as routine housekeeping alone would understate why this review is happening now, six months into the new regime, rather than on its own separate timeline. It follows a genuine, publicly documented conflict between two arms of the same government over how to apply the new tax laws — a conflict serious enough that organised private sector groups told the President directly that it had "effectively paralysed corporate tax filings across the country."

Here is the chronology, reconstructed from contemporaneous reporting:

On 3 February 2026, the Nigeria Revenue Service issued an internal memo obtained and reported by the Foundation for Investigative Journalism (FIJ) instructing officials to assess income tax returns due for filing in the "2026 year of assessment" under the new NTA and NTAA, regardless of the filing date. In practice, this was a filing-date-based rule: if a company's return happened to fall due in 2026, the new law applied to it, even if the underlying accounting period the return covered had ended before the new laws took effect on 1 January 2026. The same memo addressed capital gains tax similarly, stating gains earned during 2025 would continue under the old Capital Gains Tax Act, while gains from 2026 onward would fall under the NTA.

The Federal Government's own General Transition Guidelines, issued by Minister Oyedele under the NTAA and NTA, took a different position; what has been described as a basis-period approach rather than a filing-date approach. Under the Guidelines: tax obligations relating to an accounting period that ended before 1 January 2026 remain governed by the repealed tax laws, even where the actual filing and payment deadline falls in 2026 or later. The Guidelines state explicitly that no tax, penalty, surcharge, interest, filing obligation, or administrative requirement under the new Acts should apply to any period before their commencement, and specifically that Companies Income Tax payable for any basis period ending before 1 January 2026 should be determined under the repealed Companies Income Tax Act, notwithstanding that the filing and payment obligation itself might only become due afterward.

These two positions are not compatible, and the conflict did not resolve itself. According to Daily Trust's reporting, the NRS Emerging Taxpayers Office in Abuja then issued a further notice, dated 23 June 2026 — in the same period the Ministerial Transition Guidelines were published — directing companies that had not yet filed their Companies Income Tax returns for the 2026 Year of Assessment to do so under the new NTA/NTAA framework regardless. The notice was unambiguous about where it stood relative to any competing guidance: "The applicable law for filing is determined by statute and not by taxpayer election, publication, administrative discretion, advisory, or any other communication suggesting an alternative filing basis. The Service has no statutory authority to process Companies Income Tax returns for the 2026 Year of Assessment under the repealed Companies Income Tax Act or any other repealed tax legislation."

This left companies caught between two official, contradictory instructions from the same government, one from the Minister of Finance, the officeholder who issued the Transition Guidelines under the very Acts creating the new regime, and one from the Nigeria Revenue Service, the agency actually processing returns day to day. The Organised Private Sector of Nigeria (OPSN) — in a joint open letter to President Tinubu signed by the leadership of the Manufacturers Association of Nigeria (MAN), the Nigerian Association of Small and Medium Enterprises (NASME), the Nigerian Association of Small Scale Industrialists (NASSI), the Nigerian Association of Chambers of Commerce, Industry, Mines and Agriculture (NACCIMA), and the Nigeria Employers' Consultative Association (NECA) — stated plainly that its members were "willing and ready taxpayers" seeking only "a clear, lawful and functional framework through which they can file accurate returns, pay taxes already accrued to the Federation, protect jobs and continue investing in Nigeria." The letter was explicit that it was not an attack on the reform agenda itself: "This Open Letter is not an attack on tax reform or lawful revenue mobilisation. It is a plea to preserve the legality, credibility and economic promise of the historic reforms championed by Your Excellency."

Briefly found no confirmation in available sourcing that this specific filing-law conflict has been formally, definitively resolved as of the subcommittee's September inauguration. Businesses that were caught in this exact 2026 Year of Assessment filing ambiguity should treat it as a live, unresolved compliance question, not a historical footnote, and this is very likely a central reason the subcommittee's scope explicitly includes reviewing "implementation gaps" and consequences that have "emerged" since the new laws took effect.

Inaugurating the Technical Subcommittee on Fiscal Policy and Tax Reforms in Abuja, Minister Oyedele framed the exercise around a specific, deliberately modest ambition: "The real test begins when the law meets the economy, as businesses interpret it, administrators implement it, investors respond to it, and citizens experience it. Implementation inevitably reveals areas requiring clarification, refinement or further reform." He was explicit that the review is not intended to reverse the 2025 reforms: "The Finance Bill 2027 should not be seen as just another annual legislative exercise. Our task is not to rewrite the 2025 reforms, but to preserve their fundamental principles while learning from implementation and responding to new economic realities."

The subcommittee's mandate spans several distinct workstreams. For the Finance Bill 2027 itself, the review covers VAT thresholds, withholding tax, capital gains treatment, and multiple taxation — all areas where, as detailed below, stakeholders have specifically requested clarity or simplification. Separately, and beyond the Finance Bill, the subcommittee will review the Deduction of Tax at Source Regulations 2024 and prepare draft revised withholding tax regulations — a workstream with direct, mechanical consequences for how much tax any payer must withhold and remit on payments to contractors, service providers, and other counterparties. It will also review the Companies Income Tax (Significant Economic Presence) Order 2020 and develop an updated framework aligned with the new tax laws and international practice — the instrument governing when a non-resident company providing digital services to Nigerian customers becomes taxable in Nigeria without any physical presence there, a rule of direct relevance to global technology and digital service providers. Beyond tax specifically, the subcommittee's scope also extends to fiscal policy and management, public financial management, debt, transparency, capital markets, and cross-border capital flows.

What the 134 Submissions Actually Asked For

Ahead of the subcommittee's inauguration, the government received 134 written submissions from across Nigeria's geopolitical zones, plus additional submissions made in hard copy, following an invitation for public input. The preliminary themes Oyedele described stakeholders raising were consistent and specific: calls to clarify and simplify VAT thresholds, withholding tax, and capital gains provisions; proposals for stronger measures against multiple taxation and improved coordination among revenue authorities; requests for greater digitalisation and data-sharing specifically to stop taxpayers being made to repeatedly submit information government agencies already hold; and a further set of proposals covering stronger taxpayer rights, faster refunds, safeguards for small businesses, and measures to improve investment and competitiveness specifically in mining, renewable energy, healthcare, and capital markets.

Oyedele set out the evaluative standard he wants the subcommittee to apply to any resulting proposal, in terms that are worth quoting directly given how much they signal about the government's framing of trade-offs: "Every tax reform produces winners and losers; the question is whether a policy is fair, efficient and competitive, not whether it is popular with everyone." He added a specific caution about revenue-focused thinking in isolation: "A provision that raises revenue may impose a far greater cost on the wider economy. The government must optimise the whole economy, not merely achieve a single objective." He also directed the subcommittee to specifically assess the economic impact of any proposed change on low-income households, workers, and businesses, and warned that overly complicated tax rules risk raising compliance costs for business generally.

Who Sits on the Subcommittee

The subcommittee is chaired by the Permanent Secretary of the Federal Ministry of Finance, with Albert Folorunsho, Chairman of the Tax Advisory Committee, serving as co-chair. Its membership draws from across government and the private sector: the Federal Ministry of Justice, the Nigeria Revenue Service, the Joint Revenue Board, the Nigeria Customs Service, the Central Bank of Nigeria, the Debt Management Office, the Budget Office of the Federation, and the Nigerian Investment Promotion Commission on the government side; and the Small and Medium Enterprises Development Agency of Nigeria, the Manufacturers Association of Nigeria, the Nigerian Economic Summit Group, the Nigerian Bar Association, the Association of National Accountants of Nigeria, the Chartered Institute of Taxation of Nigeria, the Institute of Chartered Accountants of Nigeria, the Nigerian Association of Chambers of Commerce, Industry, Mines and Agriculture, and all four major international accounting firms; Deloitte, EY, KPMG, and PwC representing the private sector and professional bodies. Folorunsho has said the committee will "develop recommendations that respond to the needs of taxpayers, businesses and government."

Who must act, and what specifically changes: Nothing changes in law yet. This is a review and recommendation-drafting process feeding into a future Finance Bill, not a Bill or regulation already in force. Businesses do not face any new filing or payment obligation arising directly from the subcommittee's work itself.

Financial and operational exposure — the live filing dispute: Any company still resolving how to treat a Companies Income Tax return for an accounting period that ended before 1 January 2026, but whose filing deadline fell in 2026, faces a genuinely unresolved compliance question — official Ministerial guidance points one way, and NRS's own operational notice points the other. Businesses in this position should seek specific professional advice on how to proceed, document their filing position and its basis clearly, and monitor the subcommittee's eventual recommendations closely, since resolving exactly this kind of conflict appears to be a central, if unstated, driver of the review.

Financial and operational exposure — Significant Economic Presence: Any organisation providing digital services to Nigerian customers without a physical Nigerian presence should track the Companies Income Tax (Significant Economic Presence) Order 2020 review closely, since the subcommittee has been explicitly tasked with updating this framework to align with both the new tax laws and international practice — a review that could directly change whether, and how, such businesses become taxable in Nigeria.

Financial and operational exposure — withholding tax: Any business making payments subject to withholding tax under the Deduction of Tax at Source Regulations 2024 should expect the mechanics of deduction to change once revised regulations are drafted, since this is an explicit, separate workstream distinct from the Finance Bill 2027 itself.

Realistic timeline: The six-week review period, running from 17 September 2026, points to completion around late October to early November 2026. Draft Finance Bill 2027 proposals should be expected to follow shortly after, though no specific publication date for either the subcommittee's findings or the draft Bill was stated in available sourcing.

What remains uncertain or pending: Whether the underlying CIT filing-law conflict between the Ministry's Transition Guidelines and the NRS's June 2026 notice has been, or will be, formally and authoritatively resolved is not confirmed in available reporting. The specific content of any Finance Bill 2027 provisions, the revised withholding tax regulations, or the updated Significant Economic Presence framework are all still to be drafted following the subcommittee's review.

Is the Technical Subcommittee going to rewrite Nigeria's 2025 tax reforms? No, based on Minister Oyedele's own framing. He was explicit that the subcommittee's task is to preserve the 2025 reforms' fundamental principles while addressing implementation gaps and unintended consequences, not to reverse or fundamentally rewrite the reforms themselves.

Why is this review happening only nine months after the new tax laws took effect? Partly, per the government's own framing, because implementation naturally reveals gaps once a law "meets the economy." But it also follows a specific, documented conflict: an NRS notice in June 2026 directly contradicted the Ministry of Finance's own Transition Guidelines on how to treat 2026 Companies Income Tax filings, a conflict organised private sector groups say froze corporate tax filing activity nationwide.

What was the actual disagreement between the NRS and the Ministry of Finance? Whether a company's Companies Income Tax liability for an accounting period ending before 1 January 2026 should be assessed under the old, repealed law (as the Ministry's Transition Guidelines state) or under the new NTA/NTAA framework simply because the filing deadline happened to fall in 2026 (the position an NRS office notice took in June 2026).

Has this filing-law dispute been resolved? We found no confirmation in available reporting that it has been formally and definitively resolved as of the subcommittee's September 2026 inauguration. Affected businesses should treat it as an active, unresolved question and seek specific professional advice.

What is the Significant Economic Presence Order, and why does it matter for foreign digital businesses? It's the 2020 framework determining when a non-resident company supplying digital services to Nigerian customers becomes taxable in Nigeria despite having no physical presence there. The subcommittee is specifically tasked with updating this Order to align with the new tax laws and international practice, which could change compliance obligations for global technology and digital service providers.

How can stakeholders still influence the Finance Bill 2027? The government had already received 134 written submissions, plus additional hard-copy submissions, from across Nigeria's geopolitical zones by the time the subcommittee was inaugurated. No formal submission deadline was stated in available sourcing, but given the six-week review window, further input is likely to carry the most weight if submitted promptly.
