Nigeria is facing a constitutional test after lawmakers uncovered material discrepancies between tax reform bills passed by the National Assembly and the versions later gazetted and circulated as law.
The discovery has triggered a formal investigation by the House of Representatives and raised grave concerns about executive overreach, legislative integrity, and the rule of law.
This report reconstructs what happened, what changed, who is involved, and why the outcome matters.
What Parliament Passed — and What Changed
In December 2025, the National Assembly concluded work on a package of tax reform bills following clause-by-clause consideration and harmonisation between both chambers. The bills were transmitted for presidential assent and, according to parliamentary procedure, should have been gazetted exactly as passed.
However, lawmakers say the versions that later surfaced in the official gazette did not fully match the texts approved on the floor.
According to multiple members who reviewed the documents, the discrepancies went beyond typographical errors and included substantive provisions with legal and financial consequences.
Key differences flagged by lawmakers include: New enforcement powers appearing in the gazetted version that were not debated or approved
Altered tax appeal procedures, including requirements for advance payments before disputes can be heard
Currency and assessment provisions changed in ways that could affect taxpayers and businesses
Omissions or rewrites of clauses previously adopted by Parliament
The House described the situation as a potential post-legislative alteration of law, a move that would be unconstitutional if proven.
Constitutional Red Line
Under Sections 4 and 58 of the 1999 Constitution, law-making authority resides exclusively with the National Assembly. Once a bill is passed and assented to, no arm of government has the power to rewrite it outside a new legislative process.
Senior legal analysts consulted by BerexNews say that any alteration after passage and assent would amount to:
Usurpation of legislative powers
Executive overreach by fiat Grounds for judicial invalidation of affected provision
“This is not a procedural disagreement; it is a constitutional matter,”
one constitutional lawyer told BerexNews.
“If laws can be changed after Parliament has voted, legislative democracy collapses.”
Where the Executive Comes In
The Presidency has denied deliberately altering any law, with officials arguing that only certified, harmonised copies approved by the Clerk of the National Assembly should be considered authentic. They suggest that some circulating documents may be drafts or unofficial versions.
But lawmakers counter that the gazetted texts — which carry legal force — are precisely the issue, insisting that the burden of proof now lies with the executive to explain how unauthorised clauses entered the final publication.
President Bola Tinubu has not publicly commented in detail on the discrepancies, leaving the matter to institutional resolution between arms of government.
The Federal Inland Revenue Service(FIRS) Question — What Is Known and What Is Not
Attention has inevitably turned to the Federal Inland Revenue Service (FIRS), the agency responsible for implementing the tax laws.
The Executive Chairman of FIRS, Zacch Adedeji, has not been accused by the National Assembly of personally altering the bills. There is also no evidence linking him directly to the drafting or gazetting of the disputed changes.
What is clear, however, is that FIRS stands at the centre of implementation, making clarity critical.
Tax experts warn that enforcing disputed provisions before the investigation is concluded could expose the agency — and the government — to legal challenges and compliance resistance.
Important clarification:
Despite rumours circulating online, no “dentist” has been named, identified, or linked by Parliament or investigators to this controversy.
BerexNews found no official record or credible report supporting that claim.
Parliament Pushes Back In response, the House of Representatives has set up an ad-hoc investigative committee to:
Compare the passed bills with the gazetted versions line-by-line
Establish where discrepancies occurred
Identify responsibility within the legislative-executive chain
Recommend corrective and accountability measures Lawmakers insist the issue is not partisan but institutional.
“This is about protecting the sanctity of the law-making process,” a senior legislator said. “No democracy survives if laws are rewritten after Parliament votes.”
Democratic accountability: Separation of powers must be preserved
If left unresolved, experts warn the controversy could set a precedent where gazette publication becomes a backdoor for law-making, bypassing elected representatives.
The House committee is expected to submit its findings in the coming weeks. Possible outcomes include:
Re-gazetting corrected versions of the laws.
