Significant controversy has erupted in Nigeria following allegations from various political and civil society entities that the gazetted versions of new tax laws, signed by President Bola Tinubu, contain substantial alterations not approved by the National Assembly. The African Democratic Congress (ADC), 2023 Labour Party presidential candidate Peter Obi, and the Civil Society Legislative Advocacy Centre (CISLAC) have all raised serious concerns, demanding immediate action from the Presidency and the National Assembly.

The core of the dispute centers on alleged discrepancies between the tax reform laws passed by the National Assembly and the versions subsequently published in the official government gazette. The House of Representatives initially sounded the alarm, highlighting that the final laws differ from what was legislated by both chambers. These new tax laws are currently scheduled to take effect on January 1, 2026.

The ADC, through its National Publicity Secretary Bolaji Abdullahi, has vehemently called for the immediate suspension of what it describes as "draconian tax laws." The party's "forensic review" reportedly established that key accountability provisions were deleted, while new provisions were inserted. These insertions allegedly grant the Executive coercive powers in tax law enforcement without judicial recourse, including the power to arrest individuals and seize property over tax-related issues. The ADC warned that such tampering with legislation after parliamentary passage signifies President Tinubu’s desire to concentrate all powers, directly assaulting constitutional governance and undermining the separation of powers. The party demanded a full legislative review, a public inquiry into the "criminal alterations," and the prosecution of any government official found culpable.

Echoing these concerns, Peter Obi accused the federal government of migrating from "padded budgets" to "forged laws." He described the discrepancies as a breakdown in proper legislative procedure that undermines constitutional governance and erodes public trust. Obi highlighted specific "outrageous" additions, including a mandatory 20% deposit requirement for tax-related court appeals, provisions for asset sales without judicial oversight, and the granting of arrest powers to tax authorities. These measures, he asserted, directly affect taxpayers' rights and access to justice. Obi demanded full disclosure of the versions passed by the National Assembly, signed by the President, and eventually gazetted, stressing that the Presidency's silence on such grave allegations of forgery and institutional sabotage is deeply disturbing.

CISLAC, Nigeria’s chapter of Transparency International, also expressed profound concern, emphasizing that any alteration of a bill after parliamentary approval falls outside Nigeria's constitutional law-making framework. Executive Director Comrade Auwal Musa Rafsanjani noted that uncertainty or lack of transparency in tax legislation could erode investor confidence, raise concerns about accountability, and lead to possible abuse of executive power. CISLAC pointed out that the original law involved extensive public consultation, and any unilateral changes violate the fundamental tax principle of representation. The organization warned that implementing a disputed framework at a time of economic hardship risks deepening inequality, discouraging compliance, and fueling public resentment. CISLAC called on the Presidency to urgently publish the exact version of the tax law assented to alongside the authenticated copy passed by the National Assembly, urging the legislature to confirm reflection of its decisions and treat any discrepancy as unconstitutional.

The consensus among these bodies is that this issue transcends mere taxation, touching upon the fundamental respect for democratic institutions and the rule of law. They collectively warn that allowing the executive to alter laws passed by elected representatives would establish a dangerous precedent, undermining the legislative authority enshrined in the Nigerian Constitution. The calls for immediate suspension, thorough investigation, and accountability highlight a critical juncture for Nigeria's governance and democratic integrity.
