The Federal Inland Revenue Service (FIRS) has confirmed that the National Identification Number (NIN) issued by the National Identity Management Commission (NIMC) now automatically serves as the Tax Identification Number (TIN) for individual Nigerians. This clarification is part of efforts to explain the changes introduced by Nigeria’s new tax laws and address growing public concerns.
The announcement was made on Monday through a public awareness message shared by the FIRS on its official X (formerly Twitter) handle. According to the Service, Nigerians do not need to apply for a new or separate tax number, as their existing NIN already performs that function.
The FIRS also clarified that registered businesses will no longer require a separate Tax Identification Number. Instead, a company’s registration number issued by the Corporate Affairs Commission (CAC), known as the RC number, will now serve as its official tax identifier.
This clarification comes amid widespread concern and confusion over provisions in the new tax laws that require a Tax ID for certain transactions, including the opening and operation of bank accounts. Some Nigerians had expressed fear that the government was introducing a new tax number or adding fresh requirements that could restrict access to basic services.
According to the Service, the Nigeria Tax Administration Act (NTAA), which is scheduled to take effect in January 2026, mandates the use of a Tax ID for specific financial and official transactions. The agency stressed that this requirement is not new, noting that similar provisions have existed since the Finance Act of 2019.
“What the new law has done is to strengthen and unify the system,” the FIRS explained.
The Service stated that the Tax ID is designed to bring together all tax identification numbers previously issued by the FIRS and State Internal Revenue Services into a single, unified identifier.
“For individuals, your NIN automatically serves as your Tax ID,” the FIRS said. “For registered companies, your CAC RC number is used. You do not need a physical card, as the Tax ID is a unique number linked directly to your identity.”
The clarification is part of a broader tax reform agenda aimed at improving efficiency, transparency, and fairness in Nigeria’s tax system. According to the FIRS, the old system allowed duplication, errors, and loopholes that made it difficult to track taxpayers properly.
In the past, individuals could have multiple tax numbers across different states, while some businesses operated without clear tax records. This made enforcement difficult and encouraged tax evasion.
By linking tax records directly to the NIN for individuals and the CAC number for companies, the government hopes to create a cleaner and more reliable tax database.
The FIRS explained that the reform is not about increasing taxes or targeting low-income earners. Instead, it is meant to ensure that everyone who earns taxable income contributes fairly, while reducing pressure on those who already pay taxes.
Nigeria has one of the lowest tax-to-GDP ratios in Africa, meaning that only a small portion of the population pays taxes. Experts have long argued that the problem is not low tax rates, but weak collection and a narrow tax base.
The new system, according to the FIRS, will help bring more people into the tax net without creating additional burdens.
The FIRS also addressed concerns about privacy and misuse of personal data. It assured Nigerians that the system is designed with safeguards to protect personal information and that data will only be used for lawful tax purposes.
“The aim is efficiency, not punishment,” the Service said. “We want a system where people can comply easily and where the government can plan better with accurate data.”
The clarification on business tax IDs is also expected to ease compliance for companies, especially small and medium-sized enterprises. In the past, businesses often had to manage multiple identification numbers for different government agencies.
Under the new system, a company’s CAC RC number will serve as its single tax identifier across federal and state tax authorities, reducing duplication and administrative stress.
Business groups have welcomed the clarification, saying it will make compliance simpler and reduce confusion. However, they have also called on the government to ensure proper sensitisation, especially for small business owners in rural and semi-urban areas.
The FIRS acknowledged the need for public education and said it will continue its awareness campaign ahead of the NTAA’s implementation in 2026. The agency urged Nigerians to ignore misinformation circulating on social media and rely on official sources for accurate information.
In recent weeks, false reports had claimed that Nigerians would need to obtain a new Tax ID card or risk losing access to their bank accounts. The FIRS described such claims as misleading and incorrect.
“There is no new card, no new number, and no hidden charges,” the Service said. “If you have a NIN, you already have a Tax ID.”
The tax reform is part of the federal government’s broader effort to modernise public administration and improve revenue generation without placing additional strain on citizens. With rising demands for infrastructure, education, healthcare, and security, authorities believe better tax administration is necessary for national development.
As January 2026 approaches, the FIRS has promised to work closely with banks, businesses, and other institutions to ensure a smooth transition. The agency says its goal is a simple, fair, and transparent tax system that works for everyone.
