What a TIN is
A Tax Identification Number (TIN) identifies you or your business for tax. Under the 2026 reform, a valid TIN is mandatory for financial transactions, and the system has moved to a single TIN per taxpayer.
Individuals: your NIN is your TIN
For individuals, your NIN now serves as your Tax ID. So most people already have the basis of a TIN — you activate/validate it for tax rather than applying for a separate number. Sole proprietors typically use their personal TIN, linked to their BVN.
Companies & business names
When you register a company with the CAC, a corporate TIN is generated as part of incorporation (CAC and the tax authority are integrated). You then activate it with the NRS to file and pay.
Activating your TIN
Confirm/activate your TIN via nrs.gov.ng (and the Joint Tax Board TIN service) so it is live on the system — you’ll need an active TIN before you can register on TaxProMax or for VAT.
Why it’s mandatory now
Without a valid TIN, businesses face full-rate withholding tax, denial of input-VAT claims and reliefs, and are treated as non-compliant. The TIN is now effectively your proof of tax compliance.
Tips
- Individuals: sort your NIN — it’s your Tax ID.
- Companies: your TIN comes with CAC registration — then activate it.
- Confirm your TIN is active before filing.
Auto-generated TIN from 2026
A significant 2026 change: when you register a business with the CAC, your TIN is generated automatically — the CAC and tax authority systems are now integrated, so your RC number (company) or BN number (business name) effectively serves as your TIN, appearing on your status report/certificate. In practice this means most newly-registered businesses no longer apply separately for a TIN. It's one of the reform's genuine simplifications: register once at CAC, and your tax identity is created at the same time.
Who needs a TIN
A Tax Identification Number (TIN) is your unique identifier in the tax system, and it's needed widely: to open a corporate bank account, to file and pay taxes, to invoice or bid for contracts (government and many private), and to obtain a Tax Clearance Certificate. Both companies and individuals engaged in taxable activity need one. So whether you're running a registered company, a business name, or working for yourself, a TIN is foundational to operating formally and staying compliant.
Activating and using it
Having a TIN generated is not always the end of the story — you may still need to activate/link it for tax purposes with the relevant authority (NRS for federal taxes; your State Internal Revenue Service for personal income tax), and keep your details current. Once active, you use your TIN on filings, payments, invoices and official transactions. Keep it safe and consistent with your other records (name, RC/BN number), and verify it if you're ever unsure it's valid — a TIN that doesn't check out will stall banking and contracts.
