Nigeria Revenue Service Introduces Unified Tax ID System for All Taxable Persons
Unified Tax ID to Transform Nigeria’s Tax Administration, Says NRS
The Nigeria Revenue Service (NRS), in collaboration with the Joint Revenue Board (JRB), has introduced a unified Taxpayer Identification (Tax ID) system for all taxable persons in Nigeria, marking a major step in the country’s ongoing tax administration reforms.

The initiative, announced through a public notice issued on May 18, 2026, is backed by Sections 6, 7, and 8 of the Nigeria Tax Administration Act, 2025. The framework makes it mandatory for every taxable individual and business operating in Nigeria to obtain a Tax ID as part of efforts to improve transparency, streamline compliance processes, and strengthen revenue administration nationwide.
According to the NRS, the new system will create a single, harmonised identity for taxpayers, allowing seamless interaction with federal and sub-national tax authorities through a unified platform.
New framework centralises taxpayer identification
Under the new system, individuals will have their Tax ID linked to their National Identification Number (NIN), while companies and organisations will be linked through their Corporate Affairs Commission (CAC) registration numbers.
The reform effectively replaces the fragmented taxpayer identification structure previously used across multiple tax authorities and agencies. The NRS stated that the objective is to establish a more integrated tax administration framework capable of reducing duplication, improving record accuracy, and simplifying tax processes for taxpayers nationwide.
The agency noted that the unified Tax ID will serve as a single point of reference for all tax-related activities, including registration, filing, payment processing, and compliance monitoring.
“This initiative forms part of ongoing efforts to strengthen tax administration, enhance transparency, and improve service delivery across the nation’s tax system,” the NRS stated in its public notice.
Part of broader tax reform agenda
The rollout forms part of Nigeria’s broader fiscal and tax reform programme introduced under the Nigeria Tax Laws 2025. The reforms followed the enactment of several key legislations signed into law by President Bola Tinubu in June 2025, including the Nigeria Tax Administration Act, the Nigeria Tax Act, the NRS Establishment Act, and the Joint Revenue Board Reform Act.
The reforms restructured the former Federal Inland Revenue Service (FIRS) into the Nigeria Revenue Service and introduced a more centralised and technology-driven tax administration framework.
Industry analysts view the unified Tax ID system as a foundational component of the government’s plan to improve non-oil revenue generation, expand the tax net, and enhance efficiency in tax collection.
The NRS had earlier launched several digital initiatives in 2026, including the Rev360 tax administration platform and an electronic invoicing and fiscal monitoring system aimed at modernising taxpayer engagement and improving compliance tracking.
Implications for businesses and individuals
For businesses, the unified Tax ID system is expected to simplify interactions with multiple tax authorities by reducing administrative duplication and harmonising taxpayer records across federal and state agencies.
Tax experts say the integration could improve data accuracy, reduce tax evasion, and support more efficient compliance enforcement. The system may also strengthen government oversight of taxable transactions through enhanced digital monitoring capabilities.
Individuals and corporate entities can retrieve their Tax IDs through the Nigerian Tax ID Portal introduced earlier this year by the JRB and the NRS. The portal became operational on January 1, 2026, as part of the transition toward a fully digitised tax administration structure.
According to official guidelines, individuals can retrieve their Tax IDs using their NIN, while registered businesses can access theirs using CAC registration details.
Revenue mobilisation remains a key priority
The implementation of the unified Tax ID system comes as the federal government intensifies efforts to strengthen domestic revenue mobilisation amid ongoing fiscal pressures and declining dependence on oil revenues.
Earlier this year, the NRS announced a revenue target of ₦40.7 trillion for 2026, significantly higher than the ₦28.23 trillion generated in 2025. The agency attributed the projection to expanded tax reforms, improved compliance measures, and the integration of additional revenue streams under the new tax framework.
The government has increasingly focused on leveraging digital infrastructure and identity-based systems to improve accountability within public finance administration.
Analysts believe the success of the unified Tax ID framework will depend largely on effective implementation, inter-agency coordination, taxpayer education, and the ability of authorities to maintain secure and reliable digital infrastructure.
Outlook
The introduction of a unified Taxpayer Identification system represents one of the most significant changes to Nigeria’s tax administration architecture in recent years. By consolidating taxpayer identities under a single framework, the NRS aims to improve operational efficiency, strengthen compliance monitoring, and support broader fiscal reform objectives.
As implementation progresses, businesses, professionals, and individual taxpayers are expected to adjust to a more integrated and digitally driven tax environment that could reshape revenue administration across Nigeria.
