Getting a Tax ID in Nigeria has become easier for individuals, as the Nigeria Revenue Service (NRS) now provides an online portal where eligible individuals can retrieve their Tax ID using their National Identification Number (NIN).
The online service allows individuals to confirm their tax identity without having to begin the process at a physical tax office.
Under Nigeria’s current tax administration framework, taxable persons are required to obtain a Tax ID, while a person who already has a valid Tax ID should not apply for or be issued another one.

If you want to know how to get your Tax ID in Nigeria using your NIN, this guide explains the process step by step.
What Is a Tax ID in Nigeria?
A Tax ID is a unique identification number used by the Nigeria Revenue Service (NRS) and the Joint Revenue Board (JRB) to identify individuals and entities for tax administration, compliance and enforcement.
The official Tax ID portal explains that the number is linked to an individual’s national identity information. For businesses and other organisations, the tax identity is linked to their Corporate Affairs Commission (CAC) registration details.
A Tax ID may be required for various official and financial activities, including certain banking transactions, employment documentation, government contracts and statutory filings.
Who Needs a Tax ID?
Taxable individuals and entities in Nigeria are required to have a Tax ID.
This includes individuals who earn income or engage in taxable activities, companies and other registered organisations, as well as certain non-residents with tax obligations in Nigeria.
The Nigeria Tax Administration Act 2025 also states that a taxable person should not apply for or be issued another Tax ID where they already have a valid one.
What You Need to Retrieve Your Tax ID Using NIN
Before starting the process, you should have:
- Your National Identification Number (NIN)
- Your first name
- Your last name
- Your date of birth
- Access to the details associated with your national identity record
The official NRS portal uses the NIN as the identity source for individual Tax ID retrieval. It also requires additional personal information to verify the identity.
How to Get Your Tax ID in Nigeria Using NIN
Follow these steps to retrieve your Tax ID online.
Step 1: Visit the Official Tax ID Portal
Go to the official Nigeria Tax ID Retrieval Portal:
taxid.nrs.gov.ng
The portal provides separate options for individuals and organisations. Individuals can use their NIN, while organisations can use their organisation name or CAC registration number.
Step 2: Select National Identification Number
On the portal, select National Identification Number as your Tax ID retrieval method.
Enter your NIN in the space provided.
Make sure you enter the correct NIN before proceeding.
Step 3: Give Consent for Identity Verification
The portal asks users to consent to the processing of their information for tax-related identity verification.
Review the consent notice and tick the appropriate box if you agree.
Step 4: Submit Your NIN
Click the Retrieve Tax ID button.
The system will use your NIN to begin checking your identity against the relevant records.
Step 5: Provide Your Personal Details
Individuals may be required to provide additional information, including their:
- First name
- Last name
- Date of birth
According to the official portal, these details are cross-referenced against national identity records as part of the verification process.
Step 6: Complete the Verification Process
The system checks the information provided against the relevant identity and tax records.
If the information matches and the records are active and consistent, the portal confirms the individual’s tax identity and displays the relevant Tax ID information.
Step 7: Save Your Tax ID
Once your Tax ID is displayed, save the information securely.
You may need it when dealing with banks, employers, government agencies or other regulated institutions.
Avoid sharing your NIN or other sensitive personal information unnecessarily.
What If Your Details Do Not Match?
If the information you provide does not match the records held by the relevant authorities, the portal may notify you that there is an inconsistency.
This can happen when details such as your name or date of birth do not correspond with the information associated with your NIN or tax records.
The NRS advises users with inconsistencies to review their information and update incorrect or outdated records through the appropriate tax authority.
If you continue to experience problems, you may need to contact the relevant tax authority or the support channels provided by the NRS and Joint Revenue Board.
Can I Get a Tax ID Without Visiting a Tax Office?
For individuals whose records can be verified successfully, the official NRS portal provides an online Tax ID retrieval process using NIN.
This means you can begin the retrieval process online instead of immediately visiting a tax office.
However, if your records contain discrepancies or cannot be successfully verified, you may need further assistance from the relevant tax authority.
How to Get a Tax ID for a Business
The process is different for organisations.
The official Tax ID portal provides an option for organisations to search using their organisation name or CAC registration number.
Businesses and other registered entities should therefore use the organisation option on the portal rather than entering an individual’s NIN.
Is Tax ID the Same as NIN?
No.
Your NIN is a national identity number issued for identification purposes, while a Tax ID is used to identify a taxable person for tax administration.
For individuals, the official Tax ID system uses the NIN as the identity source from which the tax identity is verified.
Therefore, having a NIN does not mean that the two numbers serve the same purpose.
Is Tax ID Free?
The official online Tax ID retrieval portal provides the retrieval service directly through the NRS website.
Users should be careful about individuals or websites asking for unnecessary payments to retrieve a Tax ID on their behalf.
For security, always confirm that you are using the official NRS Tax ID portal.
Can I Have More Than One Tax ID?
No.
The Nigeria Tax Administration Act 2025 provides that a taxable person who already has a valid Tax ID should not apply for or be issued another Tax ID.
Where multiple Tax IDs exist for the same taxable person, the law provides for the relevant authority to unify them.
