NIN now serves as Tax ID for Nigerians

The Federal Inland Revenue Service (FIRS) has announced that the National Identification Number (NIN) issued by the National Identity Management Commission (NIMC) will now serve as the Tax Identification Number (TIN) for individual Nigerians. This clarification is part of a public awareness campaign on the new tax laws, aimed at simplifying taxpayer identification and preventing tax evasion.

According to the FIRS, registered businesses will no longer need a separate Tax ID; their Corporate Affairs Commission (CAC) registration number will function as the official tax identifier. This change is incorporated into the revised system under the Nigeria Tax Administration Act (NTAA), which takes effect in January 2026. The NTAA mandates the use of a Tax ID for specific transactions, including bank account ownership. The FIRS emphasized that this requirement is not new—it has existed since the Finance Act of 2019—and has now been reinforced under the NTAA.

The Tax ID unifies all Tax Identification Numbers previously issued by the FIRS and State Internal Revenue Services into a single identifier. For individuals, the NIN automatically serves as the Tax ID, while for registered companies, the CAC registration number is used. The new system aims to eliminate duplication, prevent tax evasion, and ensure fairness by ensuring that all individuals with taxable income contribute their share.

The FIRS urged the public to disregard any misinformation about the reform, assuring Nigerians that the updated tax framework is intended to enhance efficiency and transparency in tax administration. Taxpayers do not need a physical Tax ID card, as the Tax ID is a unique number linked directly to their identity. The Service encouraged taxpayers to familiarize themselves with the new tax laws and take advantage of the simplified identification process.

Implementation of the new tax laws is expected to have a significant impact on tax administration in Nigeria. The FIRS will continue to educate the public on the changes and provide support as taxpayers transition to the new system. As the January 2026 deadline approaches, taxpayers are advised to ensure compliance with the new regulations to avoid potential penalties or disruptions to their financial transactions.
