Nigeria has taken a decisive step toward modernizing its tax regime with the passage of the Nigeria Tax Administration Act, 2025, a sweeping reform that harmonizes tax administration across the federal, state, and local levels. The new law, hailed as a game-changer by tax experts, seeks to overhaul outdated processes and replace them with a transparent, efficient, and technology-driven system.
A Unified Tax Administration Framework
For the first time in Nigeria’s history, tax administration procedures have been standardized nationwide. The Act creates uniform enforcement guidelines, clarifies jurisdictional boundaries among tax authorities, and promotes cross-tier cooperation through authorized delegations and joint audits.
Compulsory Taxpayer Registration and Identification
The law mandates that every individual and entity—whether resident, non-resident, governmental, or part of the informal sector—must register and obtain a Tax Identification Number (TIN). This TIN becomes mandatory for all tax-related transactions, with penalties for failure to update or disclose changes in operations.
Digital Filing, VAT Modernization, and Real-Time Compliance
A major innovation is the requirement for real-time and fully digital filing of tax returns, covering monthly, quarterly, and annual obligations. Value Added Tax (VAT) compliance is enhanced through fiscalization systems, while Virtual Asset Service Providers (VASPs) are required to maintain detailed transaction and customer records for regulatory purposes.
Promoting Self-Assessment and Accountability
The Act places self-assessment at the heart of Nigeria’s tax culture, allowing taxpayers to calculate and remit dues directly. However, underreporting attracts additional assessments, penalties, and interest. Authorities retain the right to issue “best of judgment” assessments and to reassess cases of fraud or misrepresentation within a six-year window or longer where necessary.
Improved Collection, Payment, and Refund Mechanisms
Corporate taxpayers, especially in upstream petroleum and LNG sectors, benefit from structured instalment payment options. The Act formalizes withholding at source for dividends, royalties, director fees, and payments to non-residents, while introducing a time-bound tax refund system for overpayments.
Tougher Anti-Avoidance Provisions
Targeting artificial arrangements and aggressive tax planning, the Act prohibits schemes lacking genuine commercial substance. Taxpayers must disclose planning structures that could generate undue tax advantages.
Expanded Enforcement Powers
Tax authorities can now inspect and seize physical or digital records, distrain assets, revoke licenses, enforce penalties, and reward whistleblowers. Enhanced collaboration between tax authorities is also embedded in the law.
Strengthened Institutional Framework
State Internal Revenue Services are now legally formalized with clear operational mandates, while tax appeal procedures have been streamlined for transparency—allowing objections, reviews, and eventual recourse to the Supreme Court. Technology deployment is now a legal requirement for e-filing, e-audits, and online tax portals.
Laying the Foundation for a Modern Tax Culture
The Nigeria Tax Administration Act, 2025 is more than legislative housekeeping—it is a blueprint for a fully modernized tax ecosystem that fosters accountability, increases revenue, reduces leakages, and rebuilds taxpayer confidence. By embedding digital compliance, harmonizing administration, and tightening enforcement, the Act positions Nigeria’s tax system for a future of transparency and efficiency.
