The Federal Inland Revenue Service (FIRS) has clarified that the National Identification Number (NIN) issued by the National Identity Management Commission (NIMC) now automatically serves as the Tax Identification Number (TIN) for individual Nigerians.
The announcement was made on Monday as part of a public awareness campaign on the new tax laws, shared by the FIRS on X.
The Service further stated that registered businesses will no longer need a separate Tax ID. Instead, their Corporate Affairs Commission (CAC) registration number will function as their official tax identifier under the revised system.
The clarification comes amid public concerns over provisions in the new tax laws requiring a Tax ID for certain transactions, including bank account ownership.
According to the FIRS, the Nigeria Tax Administration Act (NTAA), set to take effect in January 2026, mandates the use of a Tax ID for specific transactions
