How to Retrieve Your TIN Online in Nigeria Using NIN or CAC Details (JTB Step By Step)

If you’ve ever wondered how to get your Tax Identification Number (TIN) without visiting a tax office, you’re in the right place. The Nigerian government has made the process much easier with the launch of an online Tax ID portal. Whether you’re an individual or a business owner, this guide shows you exactly how to retrieve your Tax ID using your National Identification Number (NIN) or Corporate Affairs Commission (CAC) registration number.

Understanding this process is essential. Your Tax ID is not just a number — it’s a requirement for tax compliance, banking services, business operations, and many government processes in Nigeria. With the new system being more accessible online, you no longer need to register again if you already have a linked NIN or CAC registration.

What You Need to Know Before You Start

The new Nigerian Tax ID portal has been launched by the Joint Revenue Board (JRB) and the Nigerian Revenue Services (NRS), replacing older systems and unifying TIN look-ups across the country. Once live, the system will allow Nigerians to retrieve their 13-digit Tax ID directly online without duplicate registrations.

Who Can Use This Service

• Individuals with a valid NIN
• Registered businesses and organisations with a CAC registration number

This includes students, freelancers, small business owners, entrepreneurs, and larger corporate entities.

Step-by-Step: How Individuals Retrieve Their Tax ID

If you want to pull your Tax ID using your NIN, here’s how:

   • www.taxidnrs.gov.ng
2. On the homepage, select the “Individual” option.
3. Choose National Identification Number (NIN) as your retrieval method.

Tips for a Smooth Experience

• Make sure all personal or business information exactly matches official records — differences in spelling or format can lead to failed retrieval attempts.
• Your browser should be up to date, and use a stable internet connection for best results.
• If you encounter errors or mismatches, verify the details on your NIMC or CAC documents before trying again.
• Keep a copy or screenshot of your Tax ID for future reference once you retrieve it.

Why This Matters

Your Tax Identification Number is essential for:

• Opening bank accounts or maintaining active accounts
• Filing taxes and remaining compliant with Nigerian tax laws
• Registering businesses or accessing government services
• Securing loans, contracts, and formal employment

Thanks to the new online system, retrieving your Tax ID has become faster, simpler, and more convenient than ever.
