FIRS Declares NIN As The Automatic Tax ID
The Federal Inland Revenue Service (FIRS) has declared the National Identification Number, NIN, which the National Identity Management Commission (NIMC) issues, as the Tax ID required from Nigerians under the new tax regime.
The declaration comes amidst concerns expressed over a provision of the tax laws mandating a Tax ID for bank account ownership.
According to data released by the NIMC, a total of 123.9 million Nigerians had been issued the NIN as of October 2025.
In a public awareness campaign on the new tax laws posted on X on Monday, the Service also noted that for registered businesses, the RC number issued by the Corporate Affairs Commission (CAC) automatically becomes their tax ID under the new tax system.
The Nigeria Tax Administration Act (NTAA) billed to come into force from January 2026, mandates the use of Tax ID for some transactions, according to the campaign.
