If you are an individual in Nigeria and need your Tax Identification Number (Tax ID or TIN) for banking, employment, or official documentation, you can retrieve it online using your National Identification Number (NIN) through the Federal Inland Revenue Service (FIRS) portal.
This guide explains how to retrieve or confirm your Tax ID using your NIN, step by step, in a simple and clear way.
Important Note Before You Start
Under Nigeria’s 2026 tax framework:
- Your NIN now serves as your Tax ID for individuals
- However, some organisations still request a TIN for verification
- The FIRS portal helps you retrieve or confirm your Tax ID record linked to your NIN
You are not creating a new Tax ID — you are confirming an existing tax record.
Official FIRS Tax ID Portal
Use only the official FIRS website:
The process is free, online, and takes only a few minutes if your details are correct.
Who Can Use This Method?
You can retrieve your Tax ID using this method if you:
- Are an individual (not a company)
- Have a valid 11-digit NIN
- Have personal details correctly registered with NIMC
- Need to confirm or retrieve your Tax ID for official use
You do not need a registered business or company to use this option.

Step-by-Step: How to Retrieve Your Tax ID Using NIN
Follow these steps carefully:
Step 1: Visit the FIRS Tax ID Website
Go to the official portal:
Step 2: Select “Individual”
On the homepage, click the button labelled Individual to proceed.
Step 3: Choose NIN as the Retrieval Method
From the dropdown menu titled Tax ID Retrieval Method, select NIN.
Step 4: Enter Your NIN
Type in your 11-digit National Identification Number and click Retrieve Tax ID.
Step 5: Fill in Your Personal Details
A verification box will appear. Enter the following details exactly as registered with NIMC:
- First Name
- Last Name
- Date of Birth
Step 6: Give Consent
Tick the consent checkbox to allow the system to verify your identity.
Step 7: Submit Your Request
Click the Submit button to complete the process.
Step 8: View Your Tax ID
If your details match FIRS records:
- A confirmation message will appear
- Your Tax ID (TIN) will be displayed immediately on the screen
You can copy or save the number for future use.
What If Your Tax ID Does Not Appear?
If your Tax ID does not show, possible reasons include:
- Name mismatch between NIN and tax records
- Incorrect date of birth
- NIN not yet properly linked to tax records
In such cases, you may need to:
- Contact FIRS support, or
- Visit a tax office for manual assistance
Why You May Still Be Asked for a TIN
Even though NIN is now your Tax ID, some institutions still request a TIN for:
- Bank account verification
- Employment onboarding
- Legacy government systems
- Compliance checks
Retrieving your Tax ID using this portal helps resolve such requests quickly.
Final Reminder
- Retrieving a Tax ID using NIN is free
- Registration or retrieval does not automatically mean you owe tax
- Tax applies only when there is taxable income
