The federal government has made it clear: fail to file your personal income tax, and you could face sanctions. If that news caught you off guard, you’re not alone — and this guide is here to make sure you know exactly what to do, step by step, before it becomes a problem for you.

Why This Matters Right Now (Especially If You’re in Lagos)
Here’s the situation. The federal government announced it would be sanctioning Nigerians who fail to file their personal income tax. That’s not a rumor, it’s a fact.
If you’re based in Lagos, there’s actually some good news: the deadline has been extended to April 14th. That gives you a little extra breathing room, but not a reason to procrastinate. For everyone else across Nigeria’s other states, the same process applies. The deadline and local details may differ, but the steps are the same.
And if you’re reading this in 2027 or beyond, don’t worry, none of this becomes irrelevant. Filing your personal income tax is an ongoing responsibility, and understanding it now means you’ll never be caught off guard again.
As the video embeded below puts it:
“Filing your personal income tax is quite good for you and, you know, for the country.”
It’s not just about avoiding penalties. It’s about being a financially responsible person in a system that actually needs your participation to function.
Step 1: Locate Your Local Tax Office and Get Your Tax ID
The very first thing you need to do before anything else, is locate the closest tax office or Internal Revenue Service office to where you live or work. This applies whether you’re in Lagos, Abuja, Port Harcourt, or any other state in Nigeria.
Why? Because you’re going to need your personal income tax ID to file your returns. Without it, you can’t move forward.
Now, some people already have their tax ID and don’t know it. If you’ve previously worked with an organization that paid tax on your behalf, your HR department can pull that information for you. So before you make any trips, check with HR first — it could save you the stress.
But if you’ve never had one, or you’ve always been self-employed, or you genuinely have no idea, then head to your closest tax office and get it sorted. While you’re there, ask them for their official website address too — you’ll need it in the next step.
Step 2: Choose How You Want to File — Online or In-Person
Once you have your tax ID and the website address for your state’s Internal Revenue Service, you have two options for actually submitting your tax details:
- File online yourself — Visit the website, log in or register, and input your income and deduction details directly.
- Go to the tax office in person — Gather all your documents (listed below) and take them to the office, where they can help you process everything.
Either route works. The key is that you actually do it — don’t let the choice between options become an excuse to delay.
Step 3: Gather Your Documents
Whether you’re filing online or going into the office, you’ll need the same set of documents. Here’s what to pull together:
- Your salary statement — This is your record of how much you’ve been earning.
- Your payslips — These must correspond with what actually entered your bank account. Discrepancies between your payslip and your bank statement can create problems, so make sure they match.
- A document outlining your salary deductions — This is arguably the most important one. It should show all the deductions being taken from your salary: pension contributions, health insurance, the National Housing Fund, and any other deductions governed by labor law.
That last document — the one showing your deductions — is critical. The government uses it to understand how much of your income should actually be taxed. The more legitimate deductions you have, the lower your taxable income. If you don’t have this document, or you’ve been ignoring it, now is the time to chase it down from your employer.
Understanding the Tax Rate and Income Band System
Nigeria’s personal income tax doesn’t work as a flat rate. It operates on what’s called an income band system, which means how much you pay depends entirely on which income bracket you fall into. The rate ranges from 0% at the low end up to a maximum of 25% at the higher end.
This is actually good news for lower earners. If your total income is below 800,000 NGN annually, you are not required to remit personal income tax to the government at all. That’s the threshold. If you earn below it, you shouldn’t owe anything — but you must be able to prove it. Your bank statement is how you demonstrate that your income falls below that line.
If your income is above 800,000 NGN, then the band system kicks in, and the percentage you pay scales with how much you earn, up to that 25% ceiling. This is why gathering your deduction documents matters so much: legitimate deductions reduce your taxable income, which can move you into a lower band — or potentially out of the taxable range altogether.
The 193-Day Residency Rule You Probably Didn’t Know About
Here’s something that catches a lot of people off guard: you must have been resident in Nigeria for at least 193 days before you’re considered someone who is legally obligated to pay tax in Nigeria.
So if you’ve been living or working outside Nigeria for a significant part of the year, and the total time you’ve spent in Nigeria — or earning income in Nigeria — doesn’t add up to 193 days, then you technically don’t qualify to be taxed under this system.
This matters most for people who split their time between Nigeria and other countries, or who work remotely for foreign companies while based abroad for parts of the year. Before you assume you owe taxes, work out whether you actually meet this residency requirement. It could change your situation entirely.
Step 4: File Your Return and Clear Any Outstanding Tax
Once you have your documents ready and you know which route you’re taking (online or in-person), it’s time to actually file. On the website or at the office, you’ll report how much you’ve earned over the relevant period — your full income picture, supported by the documents you’ve gathered.
One important note: if you have outstanding tax from previous years that you haven’t paid, now is the time to clear it. Don’t leave any amounts owing to the government unresolved. Unpaid taxes have a way of compounding into bigger problems down the line, and the last thing you want is for your financial future — loan applications, business registration, government contracts — to be affected because of a tax debt you let sit.
Pay what you owe, file your current returns, and get your record clean.
Quick Recap: Three Things to Always Keep in Mind
Before you close this tab and go gather your documents, here are the three most important things to hold onto:
- The 193-day rule — You need to have resided in or earned income in Nigeria for at least 193 days to be liable for personal income tax here.
- The income band system — Tax rates run from 0% to 25%, and your rate depends on which income bracket you fall into. Earn below 800,000 NGN? You likely owe nothing — but have your bank statement ready to prove it.
- Your deductions matter — Pension, health insurance, housing fund contributions — all of these reduce your taxable income. Keep the documents that prove them. They are your best tool for ensuring you’re not paying more than you should.
Go locate your nearest Internal Revenue Service office, grab your tax ID if you don’t already have it, pull your documents together, and get it filed. The process is straightforward once you know what’s involved and now you do.
