In 2025, a series of tax reform legislations were enacted in Nigeria, including the Nigerian Tax Administration Act 2025, the Nigerian Revenue Service (Establishment) Act 2025, the Joint Revenue Board (Establishment) Act 2025, and the Nigerian Tax Act 2025. These laws commenced implementation on 1 January 2026 and introduced significant structural and administrative changes to Nigeria’s tax administration framework. One of the major reforms introduced under the new regime was the operationalisation of the Nigerian Revenue Service (NRS), which replaced the Federal Inland Revenue Service and coordinated with the newly established Joint Revenue Board (JRB) in place of the former Joint Tax Board (JTB).
Implementation of the Tax ID Framework
Since January 2026, the Nigerian Revenue Service (NRS) has actively worked towards the effective implementation of the new tax laws. On the 18th day of May 2026, the NRS in conjunction with the Joint Revenue Board (JRB), issued a public notice announcing the implementation of the Taxpayer Identification (Tax ID) system. The introduction of the Tax ID system is supported by sections 6, 7 and 8 of the Nigerian Tax Administration (NTA) Act 2025, which mandates every taxable person in Nigeria to obtain a Tax ID.
Who is a Taxable Person?
The NTA Act 2025 defines a Taxable person as an individual, company, body corporate or government agency engaged in economic activity, trade, business, or income generating exploitation of tangible or intangible property. The NTA Act 2025 further provides for the procedure for registration and issuance of the Tax ID..
Objectives of the Tax ID System
According to the notice, the Tax ID system intended to serve as a single and unified taxpayer identity for all tax-related transactions and engagements across federal and sub-national tax authorities. The framework is designed to consolidate taxpayer records, eliminate duplication, and improve the efficiency of tax administration. The initiative also forms part of broader efforts aimed at strengthening tax administration, improving transparency, enhancing compliance, and promoting efficient service delivery within Nigeria’s tax system..
Key Benefits of the Tax ID:
1. Single Tax Identity: One Tax ID for all tax transactions and engagements.
2. Simplified Compliance: Easier processes for registration, filing, and payment of taxes.
3. Improved Transparency: Better visibility and tracking of taxpayer records.
4. Enhanced Revenue Assurance: Reduction in tax leakages and improved accountability.
5. Data Harmonization: Alignment of taxpayer information across all tiers of government.
Administration of the TAX ID
1. Every taxable person is required to register and obtain a Tax ID for the purpose of complying with legal tax obligations
2. A taxpayer or any person required to obtain a Tax ID may be registered unilaterally by the relevant tax authority.
3. A Tax ID is nontransferable and cannot be used by multiple persons.
4. A taxpayer or an individual is only entitled to one Tax ID.
5. A tax authority is obligated to register and issue a Tax ID upon the request of every taxpayer. Where such request is rejected, the decision should be promptly communicated to the applicant.
Uses of Tax ID
1. A Tax ID shall be stated on returns, notices, correspondence and documents submitted, for tax compliance purposes.
2. A Tax ID shall be stated on a document prepared, produced, issued or submitted in respect of taxable transactions.
3. A Tax ID is a criterion for entering into contracts with federal or state ministries, departments, agencies and local government authorities.
Transition from Existing TIN Structure
The public notice further informed Ministries, Departments, and Agencies (MDAs), financial institutions, and other organisations currently utilizing the TIN Validation API that the new Tax ID system would replace the existing TIN Validation API for all tax related purposes.
However, the NTA Act 2025 does not expressly address the continued validity or transitional treatment of existing Tax Identification Numbers (TINs). This creates potential uncertainty regarding the legal status and operational continuity of previously issued TINs pending full migration to the Tax ID framework.
The press release nevertheless indicates that the NRS and JRB are taking steps towards integration and validation of taxpayer information. Individuals, enterprises, and business names are advised to contact the Standardisation and Modernisation Department of the JRB through smd@jrb.gov.ng, while corporate entities are advised to contact the Tax Automation Department of the NRS through tax.automation@nrs.gov.ng for access to the Tax ID API and related integration guidelines
Practical Implications
The introduction of the Tax ID framework is expected to significantly affect taxpayers, financial institutions, government agencies, and businesses operating within Nigeria. Taxpayers and corporate entities are advised to review their existing tax registration records, ensure proper alignment of taxpayer information, and monitor further regulatory directives regarding migration from the former TIN structure to the new Tax ID system. Financial institutions and other regulated entities may also be required to update their compliance systems and data integration processes to accommodate the new framework.
