What Is A Tax Identification Number (TIN)?
A Tax Identification Number (TIN) is a unique number issued by Nigerian tax authorities to identify individuals and businesses for tax purposes.
Think of it like this:
- NIN identifies you as a citizen
- BVN identifies you in the banking system
- TIN identifies you as a taxpayer
Once issued, your TIN stays with you for life. You do not need multiple TINs, even if you change jobs, start a business, or relocate.
What Is The TIN Registration Portal?
The TIN registration portal is the official online system used to register and manage Tax Identification Numbers in Nigeria.
It is coordinated by the Joint Tax Board (JTB) and implemented through:
- Federal Inland Revenue Service (FIRS) for companies and federal taxpayers
- State Internal Revenue Services (SIRS) for individuals and small businesses
Through the portal, users can:
- Register for a new TIN
- Verify an existing TIN
- Retrieve lost TIN details
- Link TIN with other government records
