How to Retrieve Your Tax ID Using Your NIN

What is a Tax Identification Number (Tax ID)?

A Tax Identification Number (Tax ID) is a unique number jointly issued by the Nigeria Revenue Service (NRS) and the Joint Revenue Board (JRB) in accordance with Nigerian tax laws for the purpose of identifying individuals and entities for tax administration, compliance, and enforcement.

Under Nigeria’s tax administration framework, a Tax ID is not created in isolation.

It is derived from and linked to officially recognized foundational identity systems, including:

• National Identification Number (NIN) issued by the National Identity Management Commission (NIMC) for individuals
• National Identification Number (NIN) issued by the National Identity Management Commission (NIMC) for individuals
• Corporate Affairs Commission (CAC) registration records for companies, business names, partnerships, and incorporated trustees
• Other legally recognized identity records for non-residents and special entities

This linkage ensures that every Tax ID corresponds to a verified legal identity, improving accuracy, integrity, and trust in Nigeria’s tax system.
