Tanimu Yakubu, Director-General, Budget Office of the Federation, has spoken on the Publication Timeline of Quarterly Budget Implementation Reports.

The Budget Office of the Federation said it acknowledged public concerns regarding the publication timeline for the recent Quarterly Budget Implementation Reports, and considered it important to provide clarification within the broader constitutional and fiscal context governing public finance administration in Nigeria.

The Budget Office stated the fiscal year is not necessarily synonymous with the calendar year.

Yakubu also noted the calendar year is a fixed chronological construct of twelve months running from January to December.

He, however, described the fiscal year as a juridical and legislative creation whose duration, commencement, and terminal date are determined by the extant appropriation framework enacted by law. Accordingly, where the prevailing Appropriation Act or related legislative instrument authorises expenditure, implementation, or validity beyond the ordinary twelve-month cycle, the operative fiscal year correspondingly assumes that legally extended character, he stated.

The Director-General, Budget Office of the Federation further said in the case of the Federal Government of Nigeria, the practical operation of fiscal administration had at various times departed from the strict January–December calendar cycle through statutory extensions, supplementary appropriations, continuing resolutions, rollover authorisations, and Appropriation (Repeal and Re-enactment) Acts.

Yakubu explained the recent adjustment in the publication schedule arose principally from the Repeal and Re-enactment process of the 2025 Appropriation Act concluded December 2025, together with the subsequent extension of the implementation period of the 2025 Budget to June 2026.

These fiscal adjustments effectively extended the operational lifespan of the 2025 Budget beyond the conventional twelve-calendar-month framework ordinarily associated with a fiscal year, he said.

The Budget Office clarifies that in substance and in law, therefore, the fiscal year becomes not merely a chronological concept, but a legislatively sustained expenditure window.

He stated: “This distinction is well recognised in comparative public finance jurisprudence and constitutional practice.

In the United States, for example, the federal fiscal year runs from October 1 to September 30 pursuant to statutory prescription rather than the calendar year, while in India the fiscal year historically runs from April 1 to March 31. ” “These examples demonstrate that fiscal years are policy and legislative constructs designed to accommodate macroeconomic management realities, budget implementation imperatives, and public finance administration.”

Yakubu as well pointed out the Nigerian constitutional practice equally supports this interpretation.

The Director-General said Sections 80 and 81 of the Constitution of the Federal Republic of Nigeria, 1999 (as amended), do not constitutionalise a rigid twelve-month fiscal implementation cycle.

He noted they rather require that withdrawals from the Consolidated Revenue Fund be authorised by an Appropriation Act or other legislation duly enacted by the National Assembly. Consequently, where the National Assembly lawfully extends, reenacts, or preserves expenditure authority beyond a single calendar year, such authority remains legally valid and enforceable until its expiration under law.

Judicial authorities in Commonwealth public finance jurisprudence have consistently emphasised the supremacy of legislative authorisation in matters of public expenditure. In Attorney-General of Bendel State v. Attorney-General of the Federation, the Nigerian Supreme Court underscored the constitutional centrality of legislative control over public revenues and expenditures.

Likewise, in Attorney-General v. De Keyser’s Royal Hotel Ltd, the principle was affirmed that executive expenditure powers are subordinate to statutory authorisation where Parliament has legislated comprehensively on the matter.

He stated the practical fiscal history also offers useful illustrations.

During periods of economic disruption, including the aftermath of the COVID-19 pandemic, several jurisdictions extended budget implementation windows to accommodate procurement delays, revenue shocks, and capital project continuity.

Nigeria itself repeatedly extended the implementation period of capital components of appropriation laws to avoid the abandonment of ongoing projects, preserve contractor liquidity, sustain employment, and maintain macro-fiscal stability.

Such extensions did not create constitutional anomalies; rather, they reaffirmed the principle that the fiscal year derives its operative life from legislative authorisation and not from the immutable chronology of the Gregorian calendar.

Following the Repeal and Re-enactment of the 2025 Appropriation Act and the extension of the implementation period, Yakubu said the Budget Office commenced comprehensive reconciliations involving revenue performance reviews, cash management adjustments, expenditure alignment, debt and financing updates, and enhanced inter-agency fiscal coordination processes to ensure the accuracy, integrity, completeness, and audit consistency of the Quarterly Budget Implementation Reports.

Accordingly, the outstanding Quarterly Budget Implementation Reports are being finalised and will be released in phases over the coming weeks. In parallel, the Budget Office is strengthening its digital reporting architecture, data harmonisation systems, and institutional coordination mechanisms to support more comprehensive, timely, and analytically robust fiscal reporting in line with evolving international public finance reporting standards.

The Federal Government, he stated, remains firmly committed to the principles of open budgeting, fiscal discipline, transparency, constitutional compliance, and accountable public financial management in accordance with global best practices.
