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.
In Nigeria, the March 31 deadline is for filing tax returns for the previous year — not the current year. Here’s how it works: 📅 How the March 31 Deadline Works March 31, 2026 → You file 2025 income March 31, 2027 → You file 2026 income March 31, 2025 → You filed 2024 income By law, individuals mustRead more
In Nigeria, the March 31 deadline is for filing tax returns for the previous year — not the current year.
Here’s how it works:
📅 How the March 31 Deadline Works
March 31, 2026 → You file 2025 income
March 31, 2027 → You file 2026 income
March 31, 2025 → You filed 2024 income
By law, individuals must file Personal Income Tax returns on or before March 31 each year, covering income earned in the preceding year.
For example:
Government recently reminded taxpayers to file 2025 returns by March 31, 2026.
This confirms the rule: You always file for last year.
Why It’s Not End of the Year
Many people think tax filing happens December, but Nigeria uses:
Tax year: January – December
Filing period: January – March (next year)
So after December ends, you have 3 months (Jan–March) to file your returns.
Who Must File (Important ⚠️)
You should file by March 31 if you are:
Salary earner (even if PAYE is deducted)
Business owner
Freelancer
Self-employed
Investor earning dividends, interest, etc.
Filing is mandatory even if you don’t owe extra tax.
Many people get confused about tax filing in Nigeria because they mix up personal income tax and company income tax Let me explain The First thing you must understand is that Personal income tax and company income tax are not the same If your business is a small business under your name like a soleRead more
Many people get confused about tax filing in Nigeria because they mix up personal income tax and company income tax
Let me explain
The First thing you must understand is that Personal income tax and company income tax are not the same
If your business is a small business under your name like a sole proprietorship or enterprise, then you will file personal income tax
If your business is registered as a limited liability company, then it will file company income tax
Now let me explain the timing in a way that even Mama Ngozi that sells Tomatoes in the Village will understand.
Imagine:
Mama Ngozi starts her tomato business in January 2026
From that day, she begins to record everything she sells and all her income
She cannot file tax immediately because she has not completed one full year of business
She will keep records from January to December 2026
After the year ends, she will now calculate everything she made
Then she will file her tax in 2027
That is how it works
Now here is the key difference many people don’t know
Personal income tax deadline is always March 31 every year
Company income tax is usually filed after the company has completed 12 months of operation
Let me tell you Another important truth
Even if you just started a business in 2026, if you had personal income in 2025, you are still expected to file your personal income tax for 2025 before March 31 2026
That is because tax is always based on the previous year
Another important thing is business commencement date
YES… When you register with FIRS, now Nigeria Revenue Service, they will ask for your business start date
That date is very important because that is when your tax record begins
From that date, you count 12 months of business operation before filing
In Simple English…
If it is personal income tax, file every year before March 31
If it is company income tax, file after one full year of business
Tax is not about when you register, it is about when you start earning and recording income
Once you understand this, you will never miss your tax deadline again and you will stay compliant without stress
