Commercial banks have urged customers to link their accounts with their National Identification Numbers or Tax Identification Numbers in preparation for the enforcement of new tax regulations.

In separate notices, the banks explained that the new laws mandate all bank accounts to be connected to a valid Tax ID before the implementation date.

The financial institutions explained that customers who do not have a Tax ID must link their accounts to their NIN.

In a notice issued on Wednesday, Fidelity Bank stated that under the Nigerian Tax Administration Act 2025, all bank accounts are required to be linked to either a Tax ID or NIN by 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.

“Please use any of the options below to submit your NIN today: Click HERE or visit the NIN portal on our website. Dial *770*02# and follow the prompts,” the bank said.

Meanwhile, Ecobank advised its customers to link their NINs on or before November 13, 2025, warning that non-compliance could lead to restrictions on their accounts.

“You can easily link your NIN and update your account details through the Ecobank Customer Information Portal at https://customerupdate.ecobank.com/ciu/login by following these steps: select update your account details, enter your account number.

“Choose your preferred OTP delivery method, select request type and choose NIN updates, input your NIN, then re-enter it for VNIN (verification), click submit to complete the process.

“Alternatively, you may contact your relationship manager or visit the nearest Ecobank branch,”
Ecobank said.

On September 9, 2025, the Federal Government gazetted Nigeria’s new tax reform laws, which are scheduled to take effect on January 1, 2026.

The reforms include the Nigeria Tax Act 2025, the Nigerian Tax Administration Act 2025, the Nigeria Revenue Service (Establishment) Act 2025, and the Joint Revenue Board (Establishment) Act 2025.
