NIN, CAC REGISTRATION NUMBERS NOW SERVE AS TAX IDS UNDER NEW NIGERIAN TAX LAWS
The National Identification Number (NIN) issued by the National Identity Management Commission (NIMC) has automatically become the Tax Identification Number (Tax ID) for individual Nigerians, according to the Federal Inland Revenue Service (FIRS).
The announcement comes amid concerns over provisions in Nigeria’s tax laws that mandate the use of a Tax ID for bank account ownership and other financial transactions.
Data released by the NIMC shows that as of October 2025, a total of 123.9 million Nigerians had been issued a NIN.
In a public awareness campaign on the new tax laws posted on X on Monday, FIRS also clarified that for registered businesses, the Corporate Affairs Commission (CAC) registration (RC) number will automatically serve as their Tax ID under the new tax system.
According to the campaign, the Nigeria Tax Administration Act (NTAA), which is scheduled to come into force in January 2026, mandates the use of a Tax ID for certain transactions as part of efforts to streamline tax administration and improve compliance.
