2. Failure to collect and verify tax IDs increases regulatory compliance risk, leading to sanctions and breaches of tax regulations in Nigeria.
 

3. Banks and fintechs use tax IDs to strengthen KYC/AML and tax reporting frameworks, reducing compliance risk in banking.


 

Introduction

Starting January 2026, Tax ID validation will be a core part of compliance for banks and fintechs. Under the Nigerian Tax Administration Act, banks and financial institutions are obligated to upgrade onboarding, Tax ID verification, and reporting systems to meet the new tax law in Nigeria and avoid compliance risks.

 

This article explains how tax IDs are used in practice for banks to meet regulatory obligations and strengthen compliance frameworks.

 

What Is a Tax ID Number Under the Nigeria Tax Law?

1. A Tax ID number is a unique identity number assigned to individuals and businesses in Nigeria to fulfill tax obligations.

 

2. The Tax ID number is embedded in the Nigeria tax law and NTAA. It enables every taxable person to be tracked or linked to the tax records controlled by the Nigeria Revenue Service (NRS). 

 

3. The Tax ID is used by banks and fintechs to verify customers, support tax reporting and meet regulatory requirements during onboarding and ongoing account monitoring.

What Is Compliance Risk in Banking?

When banks and fintechs neglect laws and regulatory guidelines, they become exposed to what we refer to as compliance risk. Compliance risk in banking occurs through sanctions, fines, account restrictions or limits as a result of non-compliance.

 

In the context of tax obligations, regulatory compliance risk arises when financial institutions do not meet requirements under Nigerian tax law. This includes failures in tax ID collection, verification, and reporting, which can trigger regulatory action and financial penalties.

 

Compliance Risk Examples Linked to Tax IDs

1. Customer onboarding without a verified Tax ID: Doing this will lead to regulatory breaches and weaken customer identity controls.
 

2. Inaccurate tax records and reporting gaps: These gaps amount to challenges during audits.
 

3. Breaches of tax regulations in Nigeria: Occur when tax IDs are missing, mismatched, or not properly validated across systems.


 

How Banks and Fintechs Use Tax IDs to Meet Compliance Requirements

Banks and fintechs use Tax ID as an identifier to meet compliance demands and reduce regulatory compliance risk under Nigerian tax law. Below is an idea of how it works:


1. The Tax ID links customers to verified tax records and supports regulatory oversight by the Nigeria Revenue Service (NRS).
 

2. Banks collect and validate the Tax ID for individuals and businesses to meet KYC and KYB requirements during onboarding. 

 

3. For individuals, the National Identification Number (NIN) is often used to retrieve or validate an existing Tax ID. While for businesses, the Tax IDs are matched against the CAC records to enhance ongoing monitoring and data accuracy.


4. Verified Tax IDs assist banks and fintechs in detecting tax evasion risks and preventing false or duplicate identities.
 

5. With digital tax reporting frameworks in place, verified Tax ID data helps institutions meet tax regulations in Nigeria.
 

6. Tax ID verification also strengthens AML controls by supporting customer risk profiling and monitoring unusual transaction patterns.

As Tax ID validation and awareness become compulsory under the new tax law in Nigeria, banks and fintechs must align onboarding processes to meet compliance demands and avoid money laundering and tax evasion.
