How to File Your Tax Return in Nigeria: A Complete Step-by-Step Guide (2026)
Everything you need to know about paying your taxes in Nigeria — whether you're a salaried employee, a freelancer, a business owner, or a side-hustler.
Let's get something out of the way: most Nigerians avoid taxes not because they're dishonest, but because the system feels confusing, intimidating, and unclear. Nobody teaches you how it works. You graduate, start earning, and suddenly you're hearing words like "PAYE," "TIN," "self-assessment," and "FIRS" thrown around — with zero guidance on what any of it actually means for you.
That ends today.
In this guide, you'll learn exactly how to file your tax return in Nigeria in 2026 — step by step, in plain English. Whether you're a 9-to-5 employee, a freelancer, a small business owner, or someone earning from multiple streams, this article covers you.
⚡ Quick Answer: In Nigeria, taxes are collected by the Federal Inland Revenue Service (FIRS) for companies and FCT residents, and by State Internal Revenue Services for individuals. Most salaried workers pay through PAYE, while self-employed individuals file annual self-assessment returns. The deadline is 31st March every year.
Who Needs to File a Tax Return in Nigeria?
Under the Personal Income Tax Act (PITA), you are required to file if you are any of the following:
- Salaried employees — even if your employer deducts PAYE monthly
- Self-employed individuals — freelancers, consultants, tradespeople, artisans
- Business owners — sole proprietors, partnerships, and registered companies
- Professionals in private practice — doctors, lawyers, accountants, engineers
- Digital entrepreneurs — content creators, social media managers, e-commerce sellers
- People with multiple income streams — salary + side business + rental income
- Anyone who earned taxable income in the previous year
⚠️ Important: Even if you earn below the taxable threshold, you may still be required to file a nil return. Ignoring this can attract penalties from your State Internal Revenue Service.
Understanding Nigeria's Tax System: The Basics
The Two Main Tax Authorities
- FIRS (Federal Inland Revenue Service) — company income tax, VAT, and taxes for FCT (Abuja) residents
- SIRS (State Internal Revenue Service) — personal income tax for individuals in each state (e.g., LIRS in Lagos, EIRS in Edo, RIRS in Rivers)
As an individual, your personal income tax is filed with your state tax authority — not FIRS.
What is PAYE?
PAYE stands for Pay As You Earn. Your employer deducts tax from your salary every month and remits it to the relevant state tax authority. Even under PAYE, you are still required to file an annual self-assessment return to declare your total income and reconcile any difference.
Nigeria's Personal Income Tax Rates (2026)
| Annual Taxable Income | Tax Rate |
|---|---|
| First ₦300,000 | 7% |

| Next ₦500,000 | 15% |
| Next ₦500,000 | 19% |
| Next ₦1,600,000 | 21% |
| Above ₦3,200,000 | 24% |
A Consolidated Relief Allowance (CRA) of ₦200,000 + 20% of gross income applies before calculating taxable income. A minimum income tax of 1% of gross income applies if your calculated tax falls below that figure.

Step-by-Step: How to File Your Tax Return in Nigeria
Get Your Tax Identification Number (TIN)
Your TIN is your unique tax ID in Nigeria. You cannot file without one.
- Visit the JTB website at jtb.gov.ng and click "TIN Registration"
- Fill the form with your BVN, NIN, and personal details — your TIN is emailed to you within minutes
- Alternatively, visit any FIRS or State IRS office with a valid ID and your BVN
Tip: If you already have a BVN, you likely already have a TIN linked to it. Verify at jtb.gov.ng using your BVN or NIN.
Gather Your Financial Documents
- Payslips for all 12 months (if employed)
- Employer's tax deduction schedule (Form H1 or equivalent)
- Bank statements showing all income received
- Invoices or payment records for freelance or business income
- Receipts for allowable deductions — NHF contributions, life insurance premiums, pension above statutory
- Previous year's tax return (for reference)
Calculate Your Taxable Income
- Start with your Gross Income — salary + all other earnings
- Subtract statutory deductions: Pension (8% of basic), NHF (2.5% of basic), NHIS
- Subtract the Consolidated Relief Allowance (CRA): ₦200,000 + 20% of gross income
- What remains is your taxable income
- Apply the tax bands progressively from the table above
Example: Annual gross income of ₦3,000,000 → CRA = ₦200,000 + ₦600,000 = ₦800,000. Taxable income = ₦2,200,000. Apply the bands from there.
File Your Annual Self-Assessment Return
The deadline is 31st March every year, covering the prior calendar year (January 1 – December 31).
Salaried employees:
- Your employer typically files on your behalf using Form A with the state IRS
- You can also file independently through your state IRS portal
- Lagos residents: use the LIRS e-Tax portal at etax.lirs.net
Self-employed individuals and business owners:
- File a Self-Assessment Return at your State IRS
- Download and complete Form A from the state IRS website
- Attach your income and expenditure statement
- Pay the tax due via the portal or an approved bank
Make Payment and Get Your Tax Clearance Certificate (TCC)
After filing, you receive a demand notice. Pay through your state IRS portal, direct bank deposit, or at a state IRS office.
After full payment, apply for your Tax Clearance Certificate (TCC) — required for government contracts, certain banking approvals, business license renewals, and importing goods above certain thresholds.
File Your Company Return (Business Owners Only)
If you run a registered company, file with FIRS via taxpromax.firs.gov.ng for:
- Companies Income Tax (CIT) — 30% of profit (20% for turnover below ₦25M; 0% for qualifying small companies in first 4 years)
- VAT — 7.5% on applicable supplies; file monthly by the 21st
- Withholding Tax (WHT) — deducted from vendor payments and remitted monthly
Common Mistakes Nigerians Make When Filing Taxes
- Not filing at all — assuming PAYE covers everything permanently
- Filing late — penalties of ₦50,000 + ₦10,000 per month of default for individuals
- Filing with the wrong authority — e.g., going to FIRS when you should be at your State IRS
- Not claiming allowable deductions — pension, NHF, and NHIS all reduce your taxable income legally
- Poor record-keeping — tax authorities can audit up to 6 years back
- Ignoring digital income — YouTube AdSense, Selar sales, affiliate commissions, and online course revenue are taxable
⚠️ Digital Income is Taxable: Money earned from YouTube, affiliate marketing, online courses, and digital platforms is taxable under Nigerian law. Declare it. Tax evasion penalties include fines and prosecution.

Avoiding taxes doesn't make you financially smart — it makes you financially exposed. The Nigerian tax system has loopholes, yes. But it also has penalties, audits, and a growing digital infrastructure that makes non-compliance increasingly difficult to hide.
The truly financially intelligent person files correctly, claims every allowable deduction, pays what is due, and uses their Tax Clearance Certificate to open doors in business and government. That's not a burden — that's leverage.
That's what Investa is about: giving you the knowledge to make smart, strategic, legal financial decisions at every stage of your money journey.
