Ah, this happens quite often — the Tax Identification Number (TIN) is essential for filing PIT, but sometimes the system doesn’t return it correctly. Here’s exactly what to do to retrieve your TIN in Nigeria:

1. Confirm Your Registration Status

Before anything else:

Go to the Federal Inland Revenue Service (FIRS) TIN portal:

https://tin.gov.ng

Use the “Verify TIN” feature to check if your TIN exists.

You’ll need your BVN and full name as registered.

If it shows a TIN, note it down.

Sometimes the system fails on “forgot TIN” because of name/BVN mismatch, so double-check your registration details.

2. Attempt Online Retrieval Correctly

If you clicked “Forgot TIN” and got no response:

Make sure you’re using the exact details used during TIN registration:

Full name as per official ID

Date of birth

BVN (Bank Verification Number)

Avoid typos or abbreviations; the system is sensitive.

3. Contact the Tax Authority

If online retrieval fails, you need direct intervention:

For Federal Employees / Non-Residents / FIRS TIN

Call or email FIRS TIN support:

Phone: +234 9 462 2222 (FIRS office)

Email: tinhelpdesk@firs.gov.ng

Provide: Full name, date of birth, BVN, phone number, and explain “I cannot retrieve my TIN online.”

For State Residents / PIT TIN

If your TIN is issued by your State IRS (like Lagos, Enugu, Oyo), contact the state tax office directly. For example:

Lagos State IRS: info@lirs.gov.ng

Enugu State IRS: info@enugustateirs.ng

Bring ID and proof of previous filing attempts when visiting physically — this helps the officers retrieve your TIN manually.

4. As a Last Resort — Re-issue

Some states / FIRS offices can reissue your TIN if it cannot be retrieved online.

This usually involves filling a TIN application form, providing your BVN, ID, and proof of prior registration.

5. Tips to Avoid Problems

Always save a digital copy or screenshot of your TIN once retrieved.

Link your TIN to your BVN — it makes recovery easier.

Avoid multiple “forgot TIN” requests online — it sometimes locks your access temporarily.

💡 Practical Step Today:

Try the Verify TIN tool at https://tin.gov.ng⁠�.

If no result, call the FIRS or state IRS help desk and provide your details.

If needed, visit the nearest IRS office with your ID and BVN for manual retrieval.
