Everything you need to know about verifying and validating your Tax Identification Number (TIN) in Nigeria for 2025. We cover both the Joint Tax Board (JTB) portal and the FIRS TIN verification portal.
Introduction
In 2025, Nigeria’s tax compliance framework continues to rely on the Tax Identification Number (TIN) system managed by the Joint Tax Board (JTB) and the Federal Inland Revenue Service (FIRS). Verification and validation of your TIN ensures that your tax records are active, accurate, and recognized across government platforms, banks, and corporate institutions.
Whether you obtained your TIN via JTB online registration or through the FIRS TIN registration portal, it is important to verify and validate your details. This article provides an in-depth explanation of how to carry out JTB TIN and FIRS TIN verification in 2025, common issues you may face, and tips to ensure your TIN remains valid.
What is TIN Verification and Validation?
TIN verification is the process of checking whether a Tax Identification Number issued by JTB or FIRS is active and correctly linked to an individual or business. TIN validation goes further to ensure that the TIN matches official identity records (NIN, CAC registration details, etc.), ensuring that it can be used for official transactions.
Banks, corporate institutions, and government agencies now require validated TINs before they approve financial transactions, loan applications, customs clearance, or contract bidding.
Why Verify and Validate Your TIN in 2025?
- Legal compliance: Ensure you meet Nigeria’s tax regulations.
- Banking access: Required for opening or maintaining business accounts.
- Government contracts: Mandatory for procurement and bidding processes.
- Customs clearance: Needed for import/export registration.
- Accuracy: Prevents errors that may block financial or tax processes.

Common Issues During TIN Verification
Error: “TIN not found”
This often means your TIN hasn’t been harmonized between JTB and FIRS. Try the other portal or contact the issuing authority.
Error: “Invalid details”
Ensure your name, CAC number, or NIN exactly matches what is on record. Even small spelling differences can cause rejection.
Portal downtime
Both portals sometimes experience heavy traffic. Try again during off-peak hours or use a stronger internet connection.
Tips to Ensure Successful TIN Validation
Difference Between JTB TIN and FIRS TIN
The Joint Tax Board (JTB) oversees the national harmonized TIN system that works across both federal and state tax authorities. The Federal Inland Revenue Service (FIRS) manages federal-level tax collection. While both issue TINs, the goal is harmonization so that one valid TIN works across all platforms.
Verification on either platform should confirm your status, but sometimes harmonization delays require checking both portals.
