How to Link Your TIN or NIN to Your Bank Account Before 2026 Account Restrictions

With the Nigerian Tax Administration Act (NTAA) 2025 taking full effect from January 1, 2026, all bank accounts must be linked to a Tax Identification Number (TIN) or, for those without a TIN, a National Identity Number (NIN). Failure to comply may result in transaction restrictions, preventing deposits, withdrawals, and other essential banking services. This guide explains how to link your TIN or NIN to your bank account to ensure uninterrupted access to your funds.

The NTAA 2025 is designed to improve tax compliance and integrate banking transactions into Nigeria’s formal financial system. Banks are legally required to verify that all account holders are registered taxpayers. Linking your TIN or NIN ensures your account remains functional, avoids penalties, supports national tax compliance, and makes access to loans, investments, and other banking services easier.

Step 1: Obtain Your TIN or NIN
If you do not have a TIN, visit the Federal Inland Revenue Service (FIRS) website or any tax office to register. For those without a NIN, visit the National Identity Management Commission (NIMC) portal to register.

Step 2: Prepare Your Documents
You will need a valid ID such as an International Passport, Driver’s License, Voter’s Card, or NIN slip. Have your TIN proof (if available) and your bank account details ready.

Step 3: Link Your TIN or NIN to Your Bank Account
Most banks allow updating TIN/NIN through mobile banking apps, internet banking, or USSD codes. Alternatively, visit your bank branch with your documents and request the update in your account records.

Step 4: Confirm Your Update
After linking, your bank should provide confirmation via SMS, email, or updated account statement. Ensure your TIN or NIN is correctly reflected in your records to avoid future restrictions.
