Does the March 31 Tax Filing Deadline Apply to Newly Registered Limited Companies in Nigeria?

Short answer: No — that March 31 tax filing deadline likely does NOT apply to your newly registered company.

Let me explain clearly.

1. It Depends on the Type of Tax Being Discussed

Most of the “File before March 31” messages circulating usually refer to:

Personal Income Tax (individuals)

Some state-level filings

Specific industry obligations

But for Limited Liability Companies, your main obligation is Companies Income Tax (CIT) regulated by the Federal Inland Revenue Service under the Companies Income Tax Act.

2. For a Newly Registered Company (Like Yours — January 2026)

Your first tax filing deadline is NOT March 31.

According to Nigerian tax rules:

Your first company tax filing is due:

The earlier of:

18 months after incorporation

OR

6 months after your first accounting year ends

Example (Your Case)

If you registered in January 2026 and choose:

Accounting year end = December 31, 2026

Then:

6 months after year end → June 30, 2027

18 months after incorporation → July 2027

So your first filing deadline becomes June 30, 2027 (earlier date)

So you are NOT required to file by March 31, 2026.

However — You Still Have Some Early Obligations

Even though you don’t need to file CIT yet, you should:

Register for Tax Identification Number (TIN)

Register for VAT (if you’re operating already)

Keep proper accounting records from day one

These are usually done after registering with the Corporate Affairs Commission.
