Do I Need to File a Tax Return in Nigeria? What the 2026 Law Actually Requires

Ask most salaried Nigerians whether they file a tax return and the answer is a variation on the same theme: my employer handles it. Tax comes out of the payslip before the money arrives, the employer remits it, and that feels like the end of the transaction.

The Nigeria Tax Administration Act 2025 — the law that governs how tax is collected from 1 January 2026 — says something different, and it says it twice.

The short answer

The law requires a return from "every taxable person whether or not liable to pay tax." Owing nothing is not a reason not to file. Being fully exempt is not a reason not to file.
Being on PAYE does not replace your own return. Your employer files a separate return about you. The Act then says, in the very next breath, that you still file one about yourself.
You have to do it without being asked. The Act says returns are filed "without notice or demand" — nobody sends you a form or a reminder first.
Not filing carries an administrative penalty of ₦100,000 for the first month and ₦50,000 for every month after. Left for a year, that is ₦650,000 — which for many earners is more than the tax itself.
Reliefs only exist if you claim them. Rent relief, pension, NHF and NHIS deductions must be claimed in writing. Unclaimed, they are simply not applied.
One thing we could not pin down: the exact filing date. Neither Act prints a calendar deadline for the individual return. More on that below, because the honest answer matters more than a confident one.

What the Act actually says

Two separate laws took effect on 1 January 2026. The Nigeria Tax Act 2025 (Act No. 7) sets out what is taxed and at what rate. The Nigeria Tax Administration Act 2025 (Act No. 5) sets out the machinery — who registers, who files, what happens if you don't. Both were published in the same Official Gazette on 26 June 2025.

The filing obligation sits in section 13(1) of the Administration Act (Gazette text):

A return of income shall be filed, in the prescribed form, with the relevant tax authority in each year of assessment and without notice or demand, by — (a) every taxable person whether or not liable to pay tax.

Three phrases in that sentence do the work.

"Every taxable person." The Act defines this as a person carrying on economic activity, or exploiting property to earn income by way of trade or business. If you earn, you are in scope.

"Whether or not liable to pay tax." This is the part that surprises people. Under the Nigeria Tax Act, the first ₦800,000 of chargeable income is taxed at 0%, and section 58 puts minimum-wage earners outside the rate table entirely. None of that removes the filing duty. Owing zero and filing nothing are two different things, and only one of them is what the law asks for.

"Without notice or demand." There is no trigger. The obligation does not begin when a letter arrives.

"But my employer already files"

Your employer does file — and it is a return about the payroll, not a return about you.

Section 14(1) requires an employer to file, by 31 January each year, a return covering everyone it employed in the previous year. Section 14(2) says that return must disclose, per employee, gross emoluments including allowances and benefits in kind, total deductions, net emoluments and tax deducted.

Then section 14(3) closes the door:

Notwithstanding the provisions of subsection (1) of this section, an employee shall file an annual return of income from all sources, including employment income, in accordance with section 13 of this Act.

"Notwithstanding" is legal shorthand for this applies even though the previous thing also applies. The employer's filing does not discharge yours. And note the phrase "from all sources" — the employee return is not a copy of the payslip. It is meant to capture the freelance work, the rent from the flat in Enugu, the side business, the consulting fee. Your employer knows about none of that, which is precisely why the Act asks you separately.

What has to go in it

Section 13(2) lists the contents: a completed self-assessment form, your income from every source for the preceding year, your personal relief and tax computation, and evidence that the tax due has been paid.

There is one extra requirement if you earn from a trade, business, profession or vocation — an audited financial statement, or a statement of accounts attested to by you. For a freelancer this is not as heavy as "audited" sounds: a statement of accounts you attest to yourself is explicitly allowed.

Section 34(1) frames the whole thing as self-assessment: you work out what you owe, and the return is treated as your own assessment of it. The tax authority can accept it, or reject it and assess you to the best of its judgement.

The reliefs you lose by not filing

This is the part that makes filing worth doing for its own sake rather than out of fear.

Under section 30 of the Nigeria Tax Act (Gazette text), the deductions available to an individual include contributions to the National Housing Fund, the National Health Insurance Scheme and a pension under the Pension Reform Act; interest on a loan for building an owner-occupied home; life assurance premiums; and rent relief of 20% of annual rent paid, capped at ₦500,000.

Section 31 then says, flatly:

Deduction shall not be allowed under this Part to any person for a year of assessment, unless claimed in writing in such form as the relevant tax authority may prescribe.

Not claimed, not allowed. Section 32 adds that the tax authority can demand documentary evidence and refuse the claim without it.

A worked example. Take a freelance designer earning ₦6,000,000 a year who pays ₦1,200,000 in rent, with no pension or NHF scheme.

Rent relief is 20% of ₦1,200,000 = ₦240,000, comfortably under the ₦500,000 cap. Chargeable income is ₦6,000,000 − ₦240,000 = ₦5,760,000. Running that through the Fourth Schedule rates:

| Band | Rate | Amount taxed | Tax | |---|---|---|---| | First ₦800,000 | 0% | ₦800,000 | ₦0 | | Next ₦2,200,000 | 15% | ₦2,200,000 | ₦330,000 | | Next ₦9,000,000 | 18% | ₦2,760,000 | ₦496,800 | | Total | | | ₦826,800 |

That is an effective rate of 13.78%. The same person who never claims the rent relief has chargeable income of ₦6,000,000, and the 18% band takes ₦3,000,000 instead of ₦2,760,000 — a total of ₦870,000.

The difference is ₦43,200, and the only thing standing between the two numbers is a claim made in writing. You can run your own figures on our PAYE and take-home pay calculator, which uses these exact bands. We looked at who gains and loses from this relief, and the documentation it needs, in our guide to rent relief.

If you are self-employed, freelance, or run a side hustle

Three provisions are worth knowing.

Simplified returns exist. Section 15 of the Administration Act lets a tax authority issue guidelines for a simplified income tax return "by low-income earners or persons operating in the informal sector." The full apparatus is not aimed at someone selling online.

Presumptive tax is the fallback, and you do not want it. Section 29 of the Nigeria Tax Act says that where income cannot be ascertained, or records are not kept well enough to allow a proper assessment, the person is assessed under a presumptive regime set by the Minister. In plain terms: keep no records and someone else decides what you earned. Keeping a simple book of what came in and went out is the cheapest insurance available.

"Small business" probably does not mean you. The Administration Act defines a small business as one with gross turnover of ₦100,000,000 or less and fixed assets under ₦250,000,000 — but with an explicit carve-out: "any business providing professional services shall not be classified as a small business." Consultants, designers, developers, accountants and lawyers are outside that definition regardless of how small the turnover is. If you have read that a small business is exempt and assumed it covered your freelance practice, check that assumption.

What it costs to ignore

The penalties are administrative, which means they apply without anyone going to court.

| Failure | Section | First month | Each month after | After 12 months | |---|---|---|---|---| | Not filing returns (or filing incomplete or inaccurate ones) | s.101 | ₦100,000 | ₦50,000 | ₦650,000 | | Not registering for tax | s.100 | ₦50,000 | ₦25,000 | ₦325,000 | | Not keeping books and records | s.102 | ₦10,000 (individual) | — | — |

Put the ₦650,000 next to the ₦43,200 of rent relief in the example above and the arithmetic makes itself. Filing badly is expensive; not filing is more expensive.

Two quieter changes worth knowing

Your bank now needs your Tax ID. Section 8(2) of the Administration Act requires anyone in banking, insurance, stock-broking or other financial services to make a Tax ID a precondition "for opening any account or operating an existing account." Note operating, not just opening — the requirement reaches accounts that already exist.

Banks report large movers, but the threshold is higher than the rumours. Section 29(1) requires banks, insurers and stock-broking firms to file annual returns naming customers whose cumulative transactions in a month reach ₦50,000,000 for an individual, or ₦250,000,000 for a company. Figures far below that circulate widely online. The Act says ₦50 million.

The deadline: what we could not confirm

We went looking for the date your individual return is due, and did not find one printed in either Act.

Section 13 requires the return "in each year of assessment" with no calendar date attached. Section 34(1) says a self-assessment return is due "on or before the due date" — and the Administration Act's interpretation section, which defines more than fifty terms including "calendar year" and "commencement of business", does not define "due date." Section 14's 31 January date belongs to the employer's return, not yours.

So the operative date comes from the relevant tax authority — for most individuals, the internal revenue service of the state where you live — rather than from the face of the Act. Historically the personal income tax return was due by 31 March, and that remains the date most practitioners work to, but we could not verify it against the 2025 legislation, so we are not going to assert it as though we had. Check your own state revenue service's guidance, and if you are near the end of March without an answer, that is the point to ask a professional rather than a search engine.

This is exactly the kind of figure that gets repeated confidently across a dozen sites until everyone believes it. Sometimes the accurate answer is "the law does not say, and here is who does."

What to actually do

Get a Tax ID if you do not have one. It is now a condition of operating a bank account, not merely opening one, and failure to register runs at ₦50,000 plus ₦25,000 a month.
Write down your income from all sources for last year — salary, freelance work, rent received, side business. The employee return is explicitly "from all sources."
Gather relief evidence before you need it: your tenancy agreement and rent receipts, pension statements, NHF and NHIS contributions. Section 32 lets the tax authority refuse a claim for want of documents.
Keep a simple record going forward if you earn outside employment. It is the difference between self-assessment and presumptive assessment.
Work out the number first. Knowing what you owe before you file makes the whole exercise shorter.

Statutory references here were read directly from the Official Gazette texts of the Nigeria Tax Act 2025 (Act No. 7) and the Nigeria Tax Administration Act 2025 (Act No. 5), both published in Gazette No. 117, Vol. 112, of 26 June 2025, and checked as of September 2026. The tax bands used in the worked example are the Fourth Schedule rates and match those in our own calculator. Where we could not confirm something from the primary text — notably the filing deadline for individual returns — we have said so rather than filled the gap. Tax law changes and its administration varies by state; this article is general information, not tax advice, and a return with real money attached is worth a professional's eyes.
