Short Answer:

No — it is NOT true that Taxpayer IDs generated online are ineffective in Lagos State.

However, some online-generated Tax IDs may need activation or proper registration before you can file tax returns smoothly.

Let me explain clearly 👇

🧾 The Truth About Online-Generated Tax IDs (Lagos State)

The Lagos State Internal Revenue Service (LIRS) officially allows Taxpayer IDs to be created online through their e-Tax portal.

According to LIRS:

You can create a Taxpayer ID online

It is sent via email or SMS

You can then use it to file taxes online

This means: ✅ Online-generated Tax IDs are valid

✅ They are recognized by Lagos State

✅ They can be used for annual tax filing

⚠️ Why Some People Say Online TIN Is Not Working

This confusion usually happens because:

1. Incomplete Registration

Some people:

Generate TIN online

But do not complete profile

Or do not assign tax office

Result: 👉 The TIN exists but not fully activated

2. Not Linked to Lagos State Residency

Lagos State taxes based on residency, not origin.

If your TIN:

Was created under another state

Or under federal system

You may need migration to Lagos State system

✅ How To Make Your Online Tax ID Fully Effective (Important)

To make sure your online-generated TIN works perfectly:

Step-by-Step Fix

Go to LIRS eTax portal

Login with your TIN

Complete profile details:

Address

Occupation

Income type

Confirm your tax office (Lagos)

Save and submit

After that: 👉 Your TIN becomes fully active

🟢 Good News (Recent Update 2026)

Lagos State now encourages electronic filing only, and the eTax platform is the official filing method.

This means:

Online TIN is now even more important

Manual systems are being phased out

My Practical Advice (Based on Your Situation)

You are asking a very smart question (especially since you’re actively filing taxes lately).

Here is what I recommend:

✔ If you already generated online TIN → Don’t panic

✔ Just login and complete profile

✔ Confirm Lagos State assignment
