The Easy Guide to Getting Your Tax ID Online with NIN and CAC

As of January 1, 2026, the long queues at tax offices are officially a thing of the past. The Joint Tax Board (JTB), now operating alongside the Nigerian Revenue Services (NRS) has launched a unified digital portal.

This new system automatically links your tax records with your National Identity Number (NIN) or your Corporate Affairs Commission (CAC) registration. 

If you are already in the national database, you likely already have a 13-digit Tax ID waiting for you. You just need to retrieve it. Here is the direct, guide to getting yours in minutes.

Why Do You Need a Tax ID?

Your Tax ID is your financial fingerprint in Nigeria. You need it for:

• Opening and maintaining corporate bank accounts.
• Applying for government loans and grants.
• Clearing goods at the port.
• Obtaining a Tax Clearance Certificate (TCC).

How to Retrieve Your Individual Tax ID (Using NIN)

If you are an individual taxpayer or a freelancer, your NIN is the key.

1. Visit the Portal: Go to www.taxidjtb.gov.ng or www.taxidnrs.gov.ng.
2. Select Category: On the homepage, click on the “Individual” tab.
3. Choose Search Criteria: Select National Identification Number (NIN) from the options.
4. Enter Details: Type in your 11-digit NIN.
5. Verify Identity: Enter your First Name, Last Name, and Date of Birth exactly as they appear on your NIN slip.
6. Retrieve: Click “Continue.” Your 13-digit Tax ID will pop up on your screen instantly.

How to Retrieve Your Business Tax ID (Using CAC)

For business owners and registered companies, the process uses your RC or BN number.

1. Access the Site: Navigate to the JTB or NRS portal.
2. Select Category: Choose the “Non-Individual” or “Business” tab.
3. Input Registration Number: Enter your CAC Registration Number (e.g., RC12345 or BN6789).
4. Confirm Records: The system will sync with the CAC database to verify your company name.
5. View ID: Once verified, your 13-digit corporate Tax ID will be displayed.

Quick Tips for a Smooth Experience

• Check Your Spelling: The most common reason for an “Error” message is a mismatch in names. Ensure your name matches your NIN record perfectly, even the middle names or initials.
• No New Registration Needed: This portal is for retrieval. If you have a NIN or a registered business, a Tax ID has likely been generated for you automatically under the new unified system.
• Screenshot It: Once your ID appears, take a screenshot or print the confirmation page immediately for your records.
