Federal Inland Revenue Service (FIRS) says the National Identification Number issued by the National Identity Management Commission (NIMC) has now automatically become a Tax ID for Nigerians.
The declaration comes amidst concerns 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 sensitization campaign on the new tax laws shared on X on Monday, FIRS explained that for registered companies, the registration number issued by the Corporate Affairs Commission (CAC) will automatically serve as their tax identification number under the new tax regime.
The sensitization further stated that the Nigeria Tax Administration Act (NTAA), scheduled to take effect from January 2026, makes the use of a Tax ID compulsory for specific transaction.
However , it noted that this requirement is not new, adding that it has existed since the Finance Act 2019 and has been strengthened under the NTAA.
The FIRS added that the new tax ID system streamlines identification, eliminates duplication, seals loopholes that enable tax evasion, and promotes fairness by ensuring that everyone who earns taxable income pays their due share.
“The Tax ID unifies all TINS previously issued by FIRS and states IRS into a single identifier.
“For individuals, your NIN automatically serves as your Tax ID, while for registered companies, your CAC RC number is used.
You do not need a physical card; the Tax ID is a unique number linked directly to your identity,” the FIRS stated.
While giving an update on the tax laws billed to take effect by January 1, 2026, Chairman of the Presidential Fiscal Policy and Tax Reforms Committee, Taiwo Oyedele, dismissed claims that all bank accounts are mandated to have a Tax Identification Number (TIN) before January 2026.
According to him, Section 4 of the NTAA requires a taxable person to require and obtain a Tax ID, and a taxable income is anyone who earns income through trade or any economic activity.
He said individuals who do not earn income, such as students and dependents, do not need to obtain a Tax ID.
Oyedele added that anyone operating a bank account for businesses, or a corporate account since 2020, already had a tax Identification number.
