FIRS Company Income Tax Return (Nigeria)

A FIRS Company Income Tax Return in Nigeria reports the figures a taxpayer must declare so the correct liability can be assessed.

Under Section 55 of CITA, every company is required to file its CIT return within six months from the end of its accounting year (i.e., by 30 June for a December year-end company). The Finance Act 2019 strengthened the self-assessment regime under CITA by requiring companies to compute and pay their tax liability with the return, without waiting for a FIRS assessment notice. FIRS administers CIT collection pursuant to the Federal Inland Revenue Service (Establishment) Act 2007 (FIRSEA 2007) and applies the transfer pricing rules under the Income Tax (Transfer Pricing) Regulations 2018 and the income tax treaty network maintained by Nigeria with over 14 treaty partners.

The CIT rate in Nigeria is 30% of the assessable profits for large companies (companies with annual turnover above NGN 100 million). For medium-sized companies (annual turnover between NGN 25 million and NGN 100 million), the rate is 20%. Small companies (annual turnover below NGN 25 million) are exempt from CIT under Section 23(1)(q) of CITA as amended by the Finance Act 2019. The minimum tax provisions under Section 33 of CITA apply where a company is otherwise not liable to CIT or where its CIT liability is below the minimum tax threshold — typically 0.5% of gross turnover for most companies.

The FIRS Company Income Tax Return must be filed electronically through the FIRS Tax Pro Max platform (taxpromax.firs.gov.ng), which replaced the earlier ITAS system. Companies must obtain a Tax Identification Number (TIN) from FIRS before filing. Supporting documents — audited financial statements, tax computation, capital allowance schedule, and withholding tax credits — must be uploaded with the return.

The legal framework governing the FIRS Company Income Tax Return (Nigeria) in Nigeria draws on several key statutes and regulatory bodies. Under Nigerian law, the Companies and Allied Matters Act 2020 (CAMA) regulates corporate entities through the Corporate Affairs Commission (CAC). The Labour Act (Cap L1 LFN 2004) and the National Industrial Court of Nigeria (NICN) govern employment disputes. The Nigeria Data Protection Regulation (NDPR) 2019 and the Nigeria Data Protection Commission (NDPC) protect personal data. The Federal Inland Revenue Service (FIRS) administers tax obligations under the Companies Income Tax Act. The Federal High Court and state High Courts have jurisdiction over civil matters. Parties executing a FIRS Company Income Tax Return (Nigeria) in Nigeria should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Companies Income Tax Act (Cap. C21, LFN 2004) sets the foundational requirements.

A FIRS Company Income Tax Return in Nigeria is required annually for all companies liable to company income tax, and must be filed on specific statutory deadlines with the Federal Inland Revenue Service.

A FIRS CIT Return is required for every Nigerian company incorporated under CAMA 2020 with the Corporate Affairs Commission (CAC) that carries on business in Nigeria and has taxable income for the relevant accounting year. The return must be filed within six months of the company's accounting year-end under Section 55(1) of CITA.

A FIRS CIT Return is needed for foreign companies that have a fixed base of business in Nigeria — such as a branch office, project office, or representative office registered with the CAC — and are therefore deemed to be carrying on business in Nigeria under Section 13 of CITA and the Significant Economic Presence (SEP) rules introduced by the Finance Act 2019.

A FIRS CIT Return is required for companies claiming pioneer status exemption under the Industrial Development (Income Tax Relief) Act (IDITRA) — such companies must still file an annual CIT return, even though no tax is payable during the pioneer period, to claim and document the exemption.

A FIRS CIT Return is needed to claim withholding tax (WHT) credits against CIT liability. Under Section 81 of CITA, WHT deducted from a company's income (e.g., on contracts, dividends, rents, and royalties) is treated as advance payment of CIT, creditable against the company's final annual CIT liability on filing of the return.

A FIRS CIT Return is required for companies applying for a CIT Clearance Certificate from FIRS — which is frequently required for contract awards from federal government MDAs, registration of mortgages, and some commercial licences — demonstrating that all CIT obligations have been discharged.

A FIRS CIT Return is needed when a company has unutilised capital allowances or losses carried forward from prior years, to confirm these are properly claimed and recorded in the FIRS assessment cycle under Sections 27-32 of CITA.

Parties in Nigeria should prepare a FIRS Company Income Tax Return (Nigeria) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under Nigerian law, the Companies and Allied Matters Act 2020 (CAMA) regulates corporate entities through the Corporate Affairs Commission (CAC). The Labour Act (Cap L1 LFN 2004) and the National Industrial Court of Nigeria (NICN) govern employment disputes. The Nigeria Data Protection Regulation (NDPR) 2019 and the Nigeria Data Protection Commission (NDPC) protect personal data. The Federal Inland Revenue Service (FIRS) administers tax obligations under the Companies Income Tax Act. The Federal High Court and state High Courts have jurisdiction over civil matters. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A complete FIRS Company Income Tax Return must contain the following essential elements and supporting schedules to be accepted by FIRS and to discharge the company's filing obligations under CITA.

Company Identification: Full legal name, Tax Identification Number (TIN), CAC RC number, registered address, nature of business, and accounting year-end date. The TIN must be obtained from FIRS before the company's first filing. The return must also disclose whether the company is part of a group subject to transfer pricing rules under the Income Tax (Transfer Pricing) Regulations 2018.

Audited Financial Statements: Attachment of the company's audited profit and loss account and balance sheet for the relevant accounting year, prepared in accordance with IFRS (for companies required to apply IFRS) or ICAN-approved standards. FIRS may request audited accounts certified by a member of the Institute of Chartered Accountants of Nigeria (ICAN) or the Chartered Institute of Taxation of Nigeria (CITN).

Tax Computation Schedule: A step-by-step computation starting from profit before tax, adding back non-deductible expenses (entertainment, depreciation, penalties), deducting allowable deductions (capital allowances under the Third Schedule of CITA, balancing charges), applying investment incentives, arriving at assessable profits, and applying the applicable CIT rate (30%, 20%, or exempt).

Capital Allowance Schedule: A detailed schedule of qualifying capital expenditures and the applicable initial and annual allowance rates under the Third Schedule of CITA. Capital allowances replace accounting depreciation as the allowable deduction for fixed assets under Nigerian tax law.

Withholding Tax Credits: A schedule of WHT certificates received during the year, with the FIRS WHT credit note references, payer names, and WHT amounts. WHT credits are deducted from the gross CIT liability to compute the net tax payable with the return.

Self-Assessment Tax Payment: Evidence of payment of CIT with the return — FIRS-generated electronic payment receipt (E-receipt) from the FIRS Tax Pro Max system or a bank remittance advice confirming deposit to the FIRS consolidated revenue account. Under CITA, tax is due on the date the return is filed.
