The Joint Tax Board of Nigeria has rolled out an online system that allows Nigerians to retrieve their Tax Identification Number without undergoing a fresh registration process.

The move is expected to simplify tax administration and remove long standing bottlenecks faced by individuals and businesses when accessing their records.

A Tax Identification Number, also known as Tax ID, is a unique 13-digit number required for tax compliance, banking transactions and several government-related services. Until now, many taxpayers relied on physical offices or intermediaries to obtain or recover the number.

Information shared via the official X handle of the Joint Tax Board and also shared on Instagram for wider reach indicated that the initiative is being implemented through a newly launched digital platform. The board now operates as the Joint Revenue Board alongside the Nigerian Revenue Services, which replaced the former Federal Inland Revenue Service.

According to the announcement:

“The portal, which goes live from January 1, 2026, will allow individual Nigerians and businesses to retrieve their tax identification number (Tax ID) using either the National Identification Number (NIN) for individuals and the Corporate Affairs Commission (CAC) registration number for businesses.”
