The Nigeria Revenue Service (NRS) on Monday announced the implementation of a unified Taxpayer Identification (Tax ID) system for all taxable persons, as part of sweeping reforms aimed at modernizing tax administration in Africa's largest economy.
Collaboration with Joint Revenue Board
NRS, in collaboration with the Joint Revenue Board (JRB), stated that the initiative was introduced under Sections 6, 7, and 8 of the Nigeria Tax Administration Act, 2025. According to a joint public notice issued by the agencies, the new Tax ID replaces the previous framework and will serve as a single identifier for taxpayers engaging with federal and sub-national tax authorities.
“This initiative forms part of ongoing efforts to strengthen tax administration, enhance transparency, and improve service delivery across the nation’s tax system,” the notice said.
Key Features of the New System
Authorities explained that the system would consolidate taxpayer records, eliminate duplication, and improve the management of tax-related information across government institutions. They added that the initiative would simplify registration, filing, and payment processes, while also improving data harmonization and reducing revenue leakages.
Under the arrangement, individuals’ National Identification Numbers (NIN) will automatically form the basis for their Tax ID, while registered businesses will use their Corporate Affairs Commission (CAC) numbers. The agencies said taxpayers could retrieve their 13-digit identifier through a dedicated online portal, stressing that most Nigerians would not be required to undertake fresh registration.
Background and Implementation
The reform follows the restructuring of the Federal Inland Revenue Service (FIRS) into the NRS and the Joint Tax Board into the JRB earlier this year, as part of broader fiscal reforms that took effect in January 2026.
Tax officials clarified that although the Tax ID would be mandatory for taxable persons carrying out transactions such as operating bank accounts, accessing financial services, and securing government contracts, there would be no immediate sanctions or automatic deductions for non-compliance. They also noted that exemptions apply to non-taxable individuals, including students and dependants.
The authorities advised organizations seeking to integrate validation services into their systems to contact the JRB’s Standardisation and Modernisation Department or the NRS Tax Automation Department. Officials said the reforms were designed to boost revenue generation, improve transparency, and accelerate Nigeria’s transition towards a fully digital tax ecosystem.
