Nigeria’s Federal Inland Revenue Service has announced that the National Identification Number issued by the National Identity Management Commission now automatically serves as the Tax Identification Number for individual Nigerians. This integration simplifies the country’s tax administration framework ahead of new regulations.
The declaration, made public on 23 December 2025, addresses growing concerns about mandatory Tax IDs for transactions such as opening or operating bank accounts. The FIRS emphasised that no separate registration is required for individuals already possessing a NIN.
“For individuals, your NIN automatically serves as your Tax ID,” the FIRS stated in its awareness campaign. Registered companies will use their Corporate Affairs Commission registration number instead.
The Nigeria Tax Administration Act, set to take effect in January 2026, mandates Tax IDs for certain activities. However, the requirement builds on provisions from the Finance Act 2019.
The unified Tax ID consolidates previous identifiers issued by the FIRS and state revenue services. It aims to eliminate duplication and streamline taxpayer tracking.
This change expands the potential tax net significantly. As of October 2025, approximately 123.9 million Nigerians had been issued NINs, according to NIMC data.
No physical Tax ID card is necessary. The identifier links directly to existing national records, facilitating seamless verification.
The FIRS urged citizens to disregard misinformation suggesting additional bureaucratic hurdles. The reform seeks greater efficiency and transparency in revenue collection.
It also targets loopholes that previously enabled tax evasion while promoting fairness among those with taxable income.
This development marks a key step in Nigeria’s ongoing tax reforms, aligning identification systems to support economic governance and compliance.
