Company Income Tax in Nigeria: Rate, Rules and Filing

A plain guide to company income tax under the Nigeria Tax Act 2025: who pays, the rates, what you can deduct and when to file.

Based on the Nigeria Tax Act 2025 and the Nigeria Tax Administration Act 2025, in force from 1 January 2026.

In 30 seconds

Company income tax, also called corporate income tax or corporate tax in Nigeria, is charged on a company's total profits for each year of assessment. A small company pays 0%. Every other company pays 30% (section 56).

A large company must also pay a top-up so that its effective tax rate is at least 15% (section 57). Most companies that are not small also pay a 4% development levy.

Who pays corporate income tax in Nigeria

A Nigerian company is taxed on its profits wherever they arise. It does not matter whether the money is brought into Nigeria (section 6).

The Act treats a company as Nigerian in three cases. It is formed, registered or incorporated in Nigeria. Its central place of management or control is Nigeria. Or its effective place of management or control is Nigeria (section 201).

A non-resident company is taxed only on income from Nigeria. This covers profit linked to a permanent establishment or a significant economic presence. It also covers payments from Nigeria for services supplied from abroad, and for insurance premiums (section 17(3)).

Tax withheld from those service and insurance payments is the final tax on the payment. The exception is a company that has a permanent establishment or significant economic presence in Nigeria (section 17(4)).

What counts as a small company

The turnover limit is the point to check, because two figures are in circulation. Published checks of the gazetted Act (TheCable and KPMG Nigeria) report gross turnover of N50,000,000 or less, with total fixed assets not above N250,000,000. They say a business that provides professional services is not a small company. An earlier harmonised version used N100,000,000.

The text of section 201 hosted on this site shows N100,000,000 and has no professional services rule. We are checking it against the Gazette page. Until that is done, treat N50,000,000 as the safe limit and confirm with the NRS.

A company must meet both the turnover limit and the fixed assets limit. If it goes over either one, it is not small and the 30% rate applies.

About the 25% rate. The President may reduce the 30% rate to 25%, by an order made on the advice of the National Economic Council. The order sets the start date. Until an order is published, 30% applies.

How to calculate company income tax in Nigeria

The Act works in five steps.

  1. Take the profit of the accounting period before the year of assessment (section 22). A new business starts from the day it begins in Nigeria and runs to the end of its first accounting period (section 22(2)).
  2. Deduct the expenses the Act allows (section 20).
  3. Add back the expenses it does not allow (section 21).
  4. Add chargeable gains. Then take off losses and capital allowances (section 27).
  5. Apply the rate in section 56. The result is the tax for the year.

A worked example

A company that is not small shows a profit of N100,000,000 in its accounts. It adds back N8,000,000 of depreciation, because depreciation is not deductible. It then claims N18,000,000 of capital allowances.

StepAmount
Profit per the accountsN100,000,000
Add back depreciationN8,000,000
Assessable profitsN108,000,000
Less capital allowances(N18,000,000)
Total profitsN90,000,000
Company income tax at 30%N27,000,000

The 4% development levy is a separate charge on top of this. This is an illustration. A real computation has more adjustments.

Expenses you can deduct

An expense is deductible if it is wholly and exclusively incurred in producing the income (section 20). The Act gives examples.

  • Interest on debt used to earn the income, within the Third Schedule limit.
  • Rent on land or buildings used in the business.
  • Salaries, wages and staff benefits.
  • Repairs to premises, plant and machinery.
  • The cost of establishing or defending title to an asset.
  • Contributions to approved pension schemes.
  • Bad and doubtful debts, with proof.
  • Research and development.
  • Assistive devices and disability-related products.

The interest cap

Interest paid to a connected person is capped. The part above 30% of earnings before interest, taxes, depreciation and amortisation (EBITDA) is not deductible.

A Nigerian subsidiary of a foreign company that carries on banking or insurance is outside the cap. Interest that is not used can be carried forward for up to five years (Third Schedule).

Expenses you cannot deduct

Section 21 bars these items.

  • Capital expenditure and capital withdrawn from the business.
  • Private or domestic spending.
  • Taxes on profits or income.
  • Depreciation and impairment. Capital allowances apply instead.
  • Fines and penalties.
  • Payments to connected persons that break the Transfer Pricing Regulations.
  • Costs of earning income that is exempt from tax.
  • Any expense on which VAT was due but not charged. For imports, the same applies where import duty was not paid.

Check your VAT. The last rule links VAT to income tax. An asset on which VAT was due but not charged may also fail to qualify for capital allowance (section 27(2)(b)).

The 15% minimum effective tax rate

section 57 adds a floor for large companies. If a company's effective tax rate for the year is below 15%, it must recompute and pay extra tax to reach 15%.

The effective rate is covered taxes divided by net income. Covered taxes are company income tax, petroleum profit tax, hydrocarbon tax, the development levy and the priority sector tax credit.

Net income is profit before tax in the audited accounts. It excludes franked investment income and what the Act calls unrealistic gains or losses.

The floor applies to two groups. The first is a company in a multinational group with aggregate group turnover of at least 750 million, or its equivalent. The gazette prints the currency symbol as £. The second is any other company with aggregate turnover of N50,000,000,000 or more in the financial year (section 57(2)).

Free zone entities are outside the floor for their approved activities. They are inside it for sales into the customs territory (section 57(3)). The Service may issue regulations and set a higher threshold (section 57(4)).

Chargeable gains

Gains on the disposal of chargeable assets are added to assessable profits to form total profits (section 27(1)). The gains rules are in sections 33 to 55. Because gains sit inside total profits, a company pays tax on them at the same rate as its other profits.

NRS guidelines dated 29 June 2026 are reported to confirm this. Company gains are taxed at the standard company rates, 0% or 30%.

Filing and paying

Filing dates and penalties sit in the Nigeria Tax Administration Act (NTAA), not in the NTA. The Nigeria Revenue Service (NRS) collects company income tax and publishes the tax calendar.

  • Annual return: within six months after the accounting year ends (NTAA section 11(5)). A new company files within 18 months of incorporation, or six months after its first accounting period ends, whichever is earlier.
  • Payment: tax is paid in equal monthly instalments, with a final instalment (NTAA section 50).
  • Late filing: N100,000 for the first month and N50,000 for each month after (NTAA section 101, as reported).
  • Accounts: attach audited financial statements.
  • Platform: the NRS launched its Rev360 platform in June 2026 to replace TaxPro Max, as reported.

The Companies Income Tax Act has been repealed: what changed

Section 195 repeals the Companies Income Tax Act, the Petroleum Profits Tax Act and the Capital Gains Tax Act, among others. The Nigeria Tax Act now holds the rules.

  • Company size has two bands: small (0%) and all others (30%).
  • Large companies face a 15% minimum effective tax rate.
  • Interest paid to connected persons is capped at 30% of EBITDA.
  • A 4% development levy replaces several separate levies.

Common mistakes

  • Deducting depreciation instead of claiming capital allowances.
  • Missing the VAT link in section 21.
  • Testing only turnover for small company status. Fixed assets count too.
  • Forgetting the development levy once the company stops being small.
  • Ignoring the 15% floor in a group or a very large company.

Frequently asked questions

What is the company income tax rate in Nigeria in 2026?

Most companies pay 30% (section 56). A small company pays 0%. The President can reduce the 30% rate to 25% by an order, but only once an order is published.

Who is a small company under the Nigeria Tax Act?

Reports on the gazetted Act give gross turnover of N50,000,000 or less and total fixed assets of N250,000,000 or less, and exclude businesses that provide professional services. An earlier version used N100,000,000. Confirm the figure with the NRS.

Do small companies pay the development levy?

No. The 4% levy does not apply to small companies or non-resident companies (section 59(1)).

What is the minimum effective tax rate?

It is a 15% floor for large companies (section 57). If covered taxes divided by net income is below 15%, the company pays extra tax to reach 15%.

Are foreign companies liable to company income tax in Nigeria?

Yes, on income from Nigeria. This includes profit linked to a permanent establishment or significant economic presence, and some payments for services from abroad (section 17).

Can I deduct depreciation?

No. Depreciation and impairment are not deductible (section 21). You claim capital allowances instead, under the First Schedule (section 27).

Is interest deductible?

Yes, if it is incurred to earn the income. Interest paid to a connected person above 30% of EBITDA is not deductible (Third Schedule).

When is the company tax return due?

Within six months after the accounting year ends, under section 11(5) of the Nigeria Tax Administration Act. A new company files within 18 months of incorporation or six months after its first accounting period, whichever is earlier.

What is corporate income tax in Nigeria?

It is the tax on company profits. The Act calls it income tax on companies. The rate is 30%, or 0% for a small company (section 56).

Is the Companies Income Tax Act still in force?

No. Section 195 repeals it from the commencement of the Nigeria Tax Act. The company tax rules are now in Chapter Two of the NTA.
