Opening a business account, bidding for a contract, or clearing goods at the port? Sooner or later someone will ask for your Tax Identification Number. Without it, a lot of official doors stay shut.
The good news is that getting one is free and easier than most people expect. Let us walk through it.
What is a Tax Identification Number?
A Tax Identification Number, often shortened to TIN, is a unique number that identifies you as a taxpayer. Every registered individual and company gets a different one. Think of it as your tax fingerprint. The government uses it to track tax records and make sure the right person is paying the right amount.
Who needs a TIN?
- Business owners opening a corporate or current account.
- Companies registered with the Corporate Affairs Commission.
- Anyone bidding for government jobs or contracts.
- Importers and exporters clearing goods.
- People who need a tax clearance certificate for visas or loans.
Good news for individuals
For most individuals, a Tax Identification Number is now generated automatically from your BVN or National Identity Number. So in many cases you already have one without knowing it. You can confirm your status through the Joint Tax Board portal or at a nearby tax office.
Documents you need
For an individual, keep these handy:
- Your BVN or National Identity Number.
- A valid means of identification.
- A recent passport photograph.
- Your residential address and contact details.
For a company, you will need your CAC registration documents, the certificate of incorporation, and the company address.
How to register for a Tax Identification Number
1. Register online
Visit the Joint Tax Board TIN portal and start a new application. Fill in your details carefully, upload what is required, and submit. Individuals usually get verified against their BVN or NIN record.
2. Or visit a tax office
If you prefer in-person help, walk into the nearest Federal Inland Revenue Service office or your State Internal Revenue Service office. Companies are handled by the federal office, while individuals are often served by the state office.
3. Get your number
Once your details check out, your TIN is issued. For individuals with a verified BVN or NIN, this can be almost instant. Companies may take a little longer because the documents are reviewed.
Common mistakes to avoid
Do not pay any agent who claims a Tax Identification Number costs money. It is free, and a middleman is not required. Enter your name and date of birth exactly as they appear on your BVN or NIN record, because a mismatch is the top reason applications stall. Keep your number safe once you get it, since you will quote it often.
Why it matters
A Tax Identification Number is not merely for big companies. It opens access to formal finance, lets you tender for contracts, and keeps your business on the right side of the law. Many banks will not open a business account without it, and you will need it before you can request a tax clearance certificate.

Frequently asked questions
How much does a TIN cost?
Nothing. Getting a Tax Identification Number is completely free, whether you are an individual or a company.
Can I check if I already have one?
Yes. Use the Joint Tax Board portal or visit a tax office with your BVN or NIN to confirm.
Do individuals really need to register?
Many individuals already have a TIN linked to their BVN or NIN. You only need to register manually if the system has no record for you.
