Introduction to Corporate Tax in Nigeria

The corporate tax rate in Nigeria varies based on company size, with 30% for large companies, 20% for medium-sized companies, and 0% for small companies, as defined under the Companies Income Tax Act (as amended by the Finance Act 2019). These tiered rates directly influence tax planning, profitability assessments, and compliance strategies.

Corporate tax obligations in Nigeria are administered by the Federal Inland Revenue Service (FIRS), which oversees registration, filing, and enforcement. Companies must comply with annual filing requirements and maintain accurate financial records to support company tax filing in Nigeria under statutory timelines. 

Many businesses utilize platforms such as Commenda to manage corporate tax filing in Nigeria, streamline reporting processes, and ensure adherence to evolving regulatory requirements.

What Is the Corporate Tax Rate in Nigeria?

The corporate tax rate in Nigeria depends on company size, based on annual turnover thresholds defined under the Companies Income Tax Act. 

  • Large Companies: 30% corporate tax rate in Nigeria for turnover above NGN 100 million.

Breakdown of Corporate Income Tax Components

The corporate tax system in Nigeria operates primarily at the federal level, with additional statutory levies that increase the overall tax burden. Corporate income tax is governed by the Companies Income Tax Act and administered centrally.

  • Corporate Income Tax (CIT):
    • Charged at 0%, 20%, or 30%, depending on the company turnover
    • Applies to worldwide income for resident companies and Nigeria-sourced income for nonresidents.
    • Large companies (turnover above NGN 100 million) are taxed at 30% on a preceding-year basis.
  • Tertiary Education Tax (TET):
    • Levied at 3% of assessable profits.
    • Typically paid alongside CIT, often on a self-assessment basis.
  • Minimum Tax:
    • 0.5% of gross turnover (less franked income) when no taxable profit is declared.
    • Exemptions apply to small companies, early-stage businesses (first four years), and certain sectors like agriculture.
  • Withholding Tax (WHT) on Investment Income:
    • Applies to dividends, interest, and royalties paid to non-residents.
    • Typically treated as a final tax for non-resident recipients.
  • Taxation of Non-Residents and Digital Companies:
    • Non-resident companies are taxed if they have a permanent establishment (PE) or significant economic presence (SEP) in Nigeria.
    • SEP may be triggered by NGN 25 million+ revenue, local domain usage, or targeted digital activity.
  • Sector-Specific Taxes:
    • Petroleum companies may be subject to the Petroleum Profits Tax (up to 85%) or the Hydrocarbon Tax under the Petroleum Industry Act.
    • Combined tax exposure in upstream oil and gas can reach up to a 60% headline rate under newer regimes. 
  • Other Key Provisions:
    • Alternative minimum and deemed profit rules allow tax authorities to assess tax where profits are understated or unclear.
    • No state or municipal corporate income taxes; corporate taxation remains exclusively federal.

This centralized structure ensures consistency in corporate taxation in Nigeria while incorporating additional rules for cross-border activities, digital businesses, and sector-specific taxation.

Corporate Tax Filing Requirements in Nigeria

Corporate tax filing in Nigeria follows a self-assessment system administered by the Federal Inland Revenue Service (FIRS). Companies must register, obtain a Tax Identification Number (TIN), and submit annual returns with supporting documentation.

  • Registration and TIN:
    • Companies must register with the FIRS and obtain a Tax Identification Number (TIN) for all federal tax filings and correspondence.
  • Filing Deadline:
    • Returns must be filed within 6 months after the financial year-end or 18 months after incorporation, whichever comes first.
    • Filing extensions of up to 2 months may be granted at the discretion of the FIRS.
  • Required Documents:
    • Audited financial statements (IFRS-compliant)
    • Tax computation for the relevant year of assessment
    • Completed and signed self-assessment forms
    • Evidence of tax payment (partial or full)
  • Payment Structure:
    • Companies may apply to pay corporate tax in up to three installments, subject to FIRS approval.
    • Installment requests must be submitted with an initial payment before the filing due date.
  • Assessment Framework:
    • Nigeria operates a self-assessment system, but the FIRS may issue a best of judgment (BOJ) assessment where returns are not filed or are deemed inaccurate.
  • Penalties For Non-Compliance:
    • Late Filing: NGN 25,000 for the first month and NGN 5,000 for each subsequent month.
    • Late Payment: 10% penalty plus interest at commercial rates.

Accurate company tax filing in Nigeria requires aligning financial reporting with statutory requirements and meeting corporate tax payment deadlines to avoid penalties, audits, and enforcement actions.

Tax Year and Payment Deadlines in Nigeria

The corporate tax year in Nigeria is based on a company’s financial accounting period rather than a fixed calendar year. While many companies adopt a 31 December year-end, alternative fiscal periods are permitted if applied consistently.

  • Taxable Period:
    • Generally aligned with the company’s financial year, though the statutory fiscal year runs from 1 January to 31 December.
  • Filing And Payment Deadline:
    • Corporate tax is due within 6 months after the end of the accounting year or 18 months after incorporation, whichever occurs first.
  • Installment Payments:
    • Companies may apply to the FIRS to pay tax in up to three instalments.
    • Early payment incentives may apply, including tax credits for advance payments.
  • Self-Assessment System:
    • Companies compute and pay their own tax liabilities, subject to FIRS review and audit.
  • Audit And Enforcement:
    • Tax authorities may conduct desk reviews, monitoring visits, or full audits within six years of filing.
    • Increased scrutiny applies to transfer pricing, non-resident companies, and digital transactions.

Nigeria does not operate a standard quarterly corporate tax system, but approved installment arrangements and strict filing timelines ensure companies meet corporate tax payment deadlines while maintaining compliance.

Withholding Taxes and Other Business Taxes in Nigeria

Withholding tax (WHT) in Nigeria serves as an advance payment of income tax and applies to specific transactions, particularly for cross-border and contract payments. These taxes form an integral part of corporation tax in Nigeria.

  • Dividends: 10% withholding tax, generally treated as final tax for non-residents.
  • Interest: 10% withholding tax on interest payments.
  • Royalties: 10% withholding tax on royalty payments.

Other key business taxes include:

  • Value Added Tax (VAT): Standard rate of 7.5%, applicable to most goods and services.
  • Capital gains tax (CGT): 10% on chargeable gains, separate from corporate income tax.

Corporate Tax Incentives, Deductions, and Exemptions

Nigeria provides a range of corporate tax incentives aimed at promoting investment, industrial growth, exports, and sector-specific development. These provisions can significantly reduce the effective corporate tax rate in Nigeria when applied in compliance with statutory requirements.

    • Interest on foreign currency domiciliary accounts is also tax-exempt.
  • Infrastructure And Investment Credits:
    • Companies investing in road infrastructure may claim tax credits against CIT liabilities, with carryforward provisions.
    • Additional investment allowances may apply to qualifying capital expenditures (subject to current legislative status).

    • Interest deductions may be limited to 30% of EBITDA for foreign related-party debt.

International Tax Treaties and Double Taxation Avoidance

Nigeria has established a network of Double Taxation Agreements (DTAs) to prevent the same income from being taxed in multiple jurisdictions and to facilitate cross-border trade and investment. 

  • Double Taxation Agreements (DTAs): Nigeria currently has DTAs in force with countries including the United Kingdom, Canada, China, the Netherlands, South Africa, France, Belgium, Singapore, Sweden, Spain, and others, providing clarity on how cross-border income is taxed.
  • Foreign Tax Relief:
    • Foreign taxes paid in a treaty country are generally allowed as a tax credit against Nigerian tax on the same income.
    • Access to treaty benefits typically requires meeting administrative and documentation requirements.
  • Reduced Withholding Tax Rates:
    • DTAs may reduce domestic withholding tax rates on dividends, interest, and royalties, lowering the overall tax burden on cross-border payments.
