Nigerian Bank to Restrict Customers’ Accounts Without TIN or NIN

• The Nigerian Tax Administration Act (NTAA) 2025 mandates that bank accounts not linked to a Tax Identification Number (TIN) or National Identity Number (NIN) may be restricted from transacting starting 2026.

Fidelity Bank Plc has announced that it will begin placing limits on bank accounts not connected to a Tax Identification Number (TIN) or National Identity Number (NIN) from January 1, 2026.

The bank disclosed this in a notification sent to customers, citing provisions of the Nigerian Tax Administration Act (NTAA) 2025.

“The Nigerian Tax Identification Act (NTAA) 2025 stipulates that all bank accounts are required to be linked to a tax ID or National Identity Number—NIN (for customers without a tax ID). This act would come into effect on January 1, 2026. This implies that accounts without tax ID or national identity number may be restricted from transacting as from January 1, 2026. To ensure your account remains accessible, please update your NIN on your account as soon as possible,” the bank’s message read.

The development follows the federal government’s announcement of a definitive timeline for stricter tax compliance, which requires banks to demand TINs from all taxable Nigerians operating bank accounts beginning in 2026.

Chairman of the Presidential Committee on Fiscal Policy and Tax Reforms, Taiwo Oyedele, confirmed the regulatory change in a recent interview shared on his X account.

He explained that the enforcement is anchored on Section 4 of the NTAA, which legally mandates all taxable persons to register and obtain a TIN.

“A taxable person is anyone who earns income through trade, business, or any economic activity. So banks must request a tax ID from taxable persons,” Oyedele stated.

He added that the policy is not entirely new, as it was first introduced under the 2020 Finance Act but has not yet been fully enforced. The NTAA now provides the necessary legal framework to ensure comprehensive compliance across the banking sector from 2026.
