What is a Tax ID (formerly TIN)?
The Tax Identification Number — now officially called a “Tax ID” under Nigeria’s new tax laws — is a unique number that identifies a specific individual or business for the purposes of paying taxes. As tax payment is mandatory for all individuals and businesses earning income, every taxable person needs a Tax ID. This article deals with Tax IDs for businesses.
A quick note on the name change: on 1 January 2026, four new tax laws came into effect — the Nigeria Tax Act 2025, the Nigeria Tax Administration Act 2025, the Nigeria Revenue Service (Establishment) Act 2025, and the Joint Revenue Board (Establishment) Act 2025. Together, they replaced most of Nigeria’s old tax laws, including the Personal Income Tax Act and the Companies Income Tax Act. They also replaced the Federal Inland Revenue Service (FIRS) with a new agency, the Nigeria Revenue Service (NRS). Under this new system, the old TINs issued by the FIRS, the Joint Tax Board, and State tax authorities have been unified into a single “Tax ID.” If your business already had a TIN before 2026, don’t worry — it remains valid.
Who needs a Tax ID?
Section 4 of the Nigeria Tax Administration Act 2025 requires every “taxable person” — anyone carrying on a trade, business, or other economic activity to earn income — to register with the tax authority and obtain a Tax ID. This covers limited liability companies, registered business names, and even individuals earning business income.
Here is the good news: if your business is registered with the Corporate Affairs Commission, you very likely already have a Tax ID. Under the harmonised system, your CAC registration number (your RC number for companies, or BN number for business names) is linked to your Tax ID automatically. This now applies to business names as well as companies — the old rule where only limited liability companies got an automatic TIN, and business names had to register with the FIRS separately (usually through VAT registration), no longer applies.
What do you need it for?
Apart from registration being mandatory, there is a long list of other things which you need a Tax ID for:
- Opening or continuing to operate a corporate bank account — Section 8 of the Nigeria Tax Administration Act 2025 requires banks and other financial institutions to obtain your Tax ID as a precondition for opening a new account or continuing to operate an existing one.
- Insurance policies, pension accounts and investment accounts,
- Government loans and contracts,
- Foreign exchange,
- Application for trade licences, import and export licences,
- Registration of motor vehicles,
- Application for a certificate of occupancy, etc.
A Tax ID is also necessary to get a tax clearance certificate for your business. You will need this as evidence that you are paying your taxes as due.
How do you get it?
This is where things have improved dramatically. You no longer need to visit a tax office with a stack of photocopied documents. If your business is already registered with the CAC, simply:
- Visit the official Tax ID portal at taxid.nrs.gov.ng (or taxid.jrb.gov.ng).
- Click the “Corporate” tab.
- Enter your CAC registration number (RC or BN number).
- Your Tax ID will be displayed instantly.
The whole process takes a few minutes and can be done from your phone. Keep a screenshot or PDF of your verification — paper TIN certificates are no longer issued, and your portal verification serves as your official proof.
If the portal returns “No Record Found,” it usually means your CAC details have not been successfully matched in the tax database. In that case, you can complete a registration through the NRS self-service portal or visit the nearest NRS office with your incorporation documents to resolve it.
How much does it cost?
Obtaining your Tax ID is FREE. You do not have to pay any fees, and you do not need to engage anyone to do it on your behalf — the retrieval process is genuinely simple enough to do yourself. If anyone asks you to pay for a Tax ID, treat that as a red flag.
How long does it take?
For businesses already in the CAC database, retrieval is instant. If you need to complete a fresh registration through the NRS portal, verification typically takes a few days.
Remember, payment of tax is a civic duty. If you are doing business in Nigeria or intending to do business, you are expected to fulfil this necessary obligation, and the first step is confirming your Tax ID.
