Why most Nigerians file tax late and how to fix it
Every year, thousands of Nigerians who genuinely intended to file their tax returns end up missing the deadline. Not because they are dishonest. Not because they do not care. But because they waited too long, did not know where to go, or thought their employer already handled it for them. This article breaks down the real reasons Nigerians file late and what to do differently so March 31, 2027 does not catch you off guard the way March 31, 2026 caught so many people.
Quick Summary
- Your employer doing PAYE does not mean you have filed your returns — every individual must still file a personal tax return by March 31 every year
- The portals crash on deadline day every year — filing on March 30 or earlier is not just smart, it is necessary
- Most Nigerians do not know which state IRS to file with — you file where you live or where your business is based, not where your employer is
- Filing a nil return is still filing — even if you owe nothing, you still need to submit
- The penalty for missing the deadline is ₦50,000 for the first month — then ₦25,000 every month after that until you file
On March 31, 2026, people were queueing outside the Federal Capital Territory Internal Revenue Service office in Abuja from early morning. Not because they wanted to be there. Because the online filing portal went down on the last possible day to file personal income tax returns for the year. Some people stood in that queue for hours and still did not get to submit. They went home that night officially non-compliant through no fault of their own.
That story played out across Nigeria on the same day. Websites were unresponsive. Phone lines were busy. People who had been meaning to file for weeks suddenly discovered that "meaning to" and "actually doing it" are two very different things when a deadline is involved.
The March 31 deadline is real. The penalties are real. And the reasons most Nigerians end up on the wrong side of it have very little to do with bad intentions.
The Biggest Reason: "My Employer Does PAYE So I Do Not Need to File"
This is the misconception that catches more Nigerians than any other.
Your employer deducts PAYE from your salary every month and sends it to the State Internal Revenue Service on your behalf. That is true. But PAYE is a payment mechanism. It is not a substitute for filing your annual return.
Every individual must file a personal return by March 31 regardless of employer PAYE deductions. This is the most widespread misconception in Nigeria's tax system.
What this means practically is that even if your employer has been perfectly deducting and remitting PAYE on your behalf every month for the past year, you still owe the government a personal tax return by March 31. That return is your formal declaration of all income you earned, all deductions you are entitled to, and confirmation that the PAYE already remitted covers what you actually owe.
If you have any income outside your regular salary, freelance work, rental income, or money from investments, the PAYE your employer remitted definitely does not cover those. But even if your salary is your only income, the filing obligation still exists.
If you have never filed a personal tax return before and your employer has always handled your PAYE, go and ask your HR department whether they also file annual returns on your behalf with the State IRS. Most smaller employers do not. Most employees do not know to ask.
The Second Reason: Not Knowing Where to File
Nigeria administers Personal Income Tax at the state level. That means you do not file with the Federal Inland Revenue Service or the NRS for your personal income tax. You file with the Internal Revenue Service in the state where you live or where your business operates.
Lagos residents file with the Lagos Internal Revenue Service at etax.lirs.gov.ng. Abuja residents file with the FCT Internal Revenue Service at irs.fct.gov.ng. Every other state has its own portal. If you live in Ogun State but work in Lagos, you file with Ogun State IRS, not Lagos.
This trips people up more than you would expect. Someone spends 45 minutes trying to create an account on the LIRS portal only to discover they should have been filing in Rivers State all along. By the time they figure it out and start again, it is already late March and the deadline is breathing down their neck.
Find out which state you are supposed to file with before any deadline pressure arrives. Do it today. It takes five minutes and removes one of the biggest sources of last-minute confusion.
The Third Reason: Waiting Until the Last Week
Thousands of Nigerian taxpayers were left stranded as technical glitches disrupted last-minute efforts to file annual tax returns on the final day. Many who thronged the offices described chaotic scenes, long queues and unresponsive online platforms, leaving them uncertain about their compliance status.
This happens every single year and it will happen again in 2027. The portals are not built for the surge of traffic that hits them on March 29, 30, and 31. The people who file in January, February, or the first two weeks of March have a completely different experience. The platform is responsive. There are no queues. Submissions go through immediately and confirmation arrives within minutes.
Filing late in the month is not laziness. It feels logical because deadlines are supposed to be the actual last day. But in practice, the Nigerian tax filing system treats the deadline as the last day you can try and that is a different thing entirely.
If your target is March 31, treat March 15 as your personal deadline. Give yourself two weeks of buffer for any technical issues, document problems, or questions you need to resolve before submitting.
The Fourth Reason: Documents Are Not Ready
The actual filing process is not complicated once your documents are in front of you. What takes time is gathering everything.
For a salaried employee, you need your employer's Tax Identification Number, your own TIN, a summary of all income earned in the year including salary and any side income, evidence of deductions you want to claim like pension statements or rent receipts, and your PAYE deduction records for the year.
For a freelancer or self-employed person, you also need records of every payment received, every business expense you want to deduct, and bank statements that support both.
The reason people miss deadlines is not usually forgetfulness. It is being unprepared. If you maintain monthly records of income, expenses, and tax deductions throughout the year, filing at deadline is just submitting what you already have.
The people who file in February are almost always the people who have been keeping organized records throughout the year. The people who miss the deadline are almost always the people who have to reconstruct twelve months of financial activity in a rush during March.

The Fifth Reason: Thinking Zero Tax Means No Filing
If you earn ₦800,000 or less per year, your income tax rate under the NTA 2025 is 0%. That is genuinely good news and it means you owe nothing.
But owing nothing is not the same as having no obligation to file.
Paying tax and filing tax returns are two different obligations. Even if you have no tax to pay, you may still be required to submit a return.
A nil return is a return that shows zero tax liability. It is how you formally tell the State IRS that you earned below the threshold and owe nothing for the year. Without it, the IRS does not know whether you simply qualify for the exemption or whether you just did not bother to file.
The penalty for not filing a nil return is the same as the penalty for not filing when you owe tax: ₦50,000 for the first month of default and ₦25,000 for every month after that. You could end up paying ₦300,000 or more in penalties for not filing a return that would have shown you owe zero naira.
The Sixth Reason: Confusion About 2026 Filing Covering 2025 Income
This one specifically tripped up a lot of people earlier in 2026 and will likely cause confusion again in 2027.
When you file in 2026, you are reporting income you earned in 2025. This means you use the old tax structure, not the new 2026 rates.
The new NTA 2025 rates with the ₦800,000 zero-tax threshold took effect on January 1, 2026. So your 2026 filing, which covers 2025 income, still uses the old rate structure. The new rates apply to income you earn in 2026, which you will file for in 2027.
This caused genuine confusion during the March 2026 filing window. People expected to see the new tax bands applied to their 2025 income and got very different numbers from what they anticipated. Some filed incorrectly. Others gave up out of confusion and did not file at all.
Knowing this in advance saves you that confusion. When you file in 2027 for your 2026 income, that is when you will see the new ₦800,000 zero-tax threshold and the updated progressive bands applied in full.
What to Do Right Now So 2027 Does Not Repeat 2026
You do not need to wait until February to start preparing for your March 31, 2027 filing. Here is what to do today.
Find out which State IRS you are supposed to file with and create an account on their portal now while there is no deadline pressure. The account creation process sometimes takes a few days.
Start a simple record of every income source you receive from January 2027 onward. A note on your phone or a basic spreadsheet is enough. Income from your job, any freelance payments, any rent you collect, any returns from investments.
Collect your deduction documents as they arrive rather than hunting for them in March. Pension statements, tenancy agreements with payment receipts, NHIS records.
Set a personal filing deadline of March 14, 2027. Two weeks before the official deadline. That buffer has saved thousands of filers from portal crashes and last-minute document emergencies.
If you missed the 2026 deadline and have not yet filed, file now. The penalty compounds monthly. Every month you wait is another ₦25,000 added to what you already owe. Filing late is significantly better than not filing at all.
Taxidy is building the platform that removes every reason on this list. Track your income as you earn it, store your deduction documents as they arrive, and generate your return when March comes around. Join the waitlist at taxidy.net.
