What Is a FIRS Objection Letter (Nigeria)?
A FIRS Objection Letter in Nigeria sets out, in writing, the request or notice the sender directs to the recipient.
Under Section 68(1) of CITA, a company that wishes to contest a FIRS assessment must file a written notice of objection with the relevant FIRS office within 30 days from the date of service of the assessment notice. The objection must state the grounds of objection in sufficient detail, specify the amount the taxpayer considers to be the correct tax liability, and be accompanied by any supporting evidence, audited accounts, computations, or legal authorities relied upon. Failure to file within 30 days results in the assessment becoming final and conclusive under Section 68(4) of CITA, depriving the taxpayer of any further right to challenge the assessment except through the discretionary extension provisions.
The FIRS objection process is the mandatory first administrative step before a taxpayer can access the Tax Appeal Tribunal (TAT) — established under the Federal Inland Revenue Service (Establishment) Act 2007 — and subsequently the Federal High Court on points of law. The TAT, constituted under Section 59 of the FIRSEA 2007 and the Tax Appeal Tribunal (Establishment, etc.) Order 2010, hears appeals from taxpayers who are dissatisfied with FIRS's determination of an objection. A taxpayer who has not filed a timely objection cannot appeal directly to the TAT.
A FIRS Objection Letter must be distinguished from a FIRS Query Response (which responds to FIRS audit queries during an ongoing investigation, before a formal assessment is raised), a Tax Appeal Tribunal Appeal (which is filed after the objection is determined, if the taxpayer remains dissatisfied), and a Request for Information (which is a voluntary response to FIRS's request for records under Section 29 of the FIRSEA 2007).
The legal framework governing the FIRS Objection Letter (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 Objection Letter (Nigeria) in Nigeria should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Federal Inland Revenue Service (Establishment) Act 2007 sets the foundational requirements.
When Do You Need a FIRS Objection Letter (Nigeria)?
A FIRS Objection Letter in Nigeria is needed whenever a taxpayer receives a FIRS assessment notice that is incorrect, excessive, or based on wrong facts or law, and wishes to preserve their rights to challenge the assessment.
A FIRS Objection Letter is required when FIRS raises a best of judgment (BOJ) assessment under Section 66 of CITA against a company that failed to file its CIT return on time, estimating the company's taxable profits at an amount the company considers excessive. The BOJ assessment is automatically raised on the FIRS's assumed profits; only a timely objection can challenge this figure.
A FIRS Objection Letter is needed when FIRS raises an additional assessment following a tax audit, claiming disallowance of deductions (such as management fees, intercompany charges, or interest on shareholder loans) that the company considers allowable under CITA or applicable tax treaties. The Finance Act 2021 introduced restrictions on interest deductibility under the earnings stripping rules; disputes on the application of these rules frequently require formal objection.
A FIRS Objection Letter is required when a company disagrees with FIRS's transfer pricing adjustment under the Income Tax (Transfer Pricing) Regulations 2018, where FIRS has re-priced intercompany transactions to reflect an arm's length price that the company considers excessive or methodologically incorrect.
A FIRS Objection Letter is needed when FIRS raises a VAT assessment under the Value Added Tax Act (VATA) Cap V1, LFN 2004, charging output VAT on supplies the company considers exempt or zero-rated under the VATA Schedules, or disallowing input VAT credits the company considers legitimate.
A FIRS Objection Letter is required when FIRS raises a withholding tax (WHT) assessment on payments the company made to contractors or service providers, claiming WHT was not deducted at the correct rate or was not remitted on time under Section 81 of CITA.
A FIRS Objection Letter is needed when a non-resident company receives a FIRS assessment on income that the company considers outside the scope of Nigerian taxation by virtue of a Double Taxation Agreement (DTA) between Nigeria and the company's home country — Nigeria has DTAs with the UK, France, South Africa, China, Belgium, the Netherlands, Romania, Pakistan, and several other countries.
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.
What to Include in Your FIRS Objection Letter (Nigeria)
A valid FIRS Objection Letter must contain the following essential elements to be accepted by FIRS and to preserve the taxpayer's statutory rights under Section 68 of CITA.
Addresee and Assessment Reference: The letter must be addressed to the relevant FIRS tax office — the integrated tax office (ITO) or large taxpayer office (LTO) responsible for the taxpayer's account. The FIRS assessment notice number, date, and the tax year to which the assessment relates must be clearly stated at the outset.
Taxpayer Identification: Full legal name of the taxpayer company, TIN, CAC RC number, and registered address as in FIRS records. For corporate taxpayers, the letter must be signed by a director, company secretary, or authorised tax representative (a tax practitioner enrolled with FIRS or a member of the Chartered Institute of Taxation of Nigeria — CITN).
Grounds of Objection: The specific factual and legal grounds on which the taxpayer disputes the assessment — for example, incorrect characterisation of income, disallowance of legitimate deductions, double taxation treaty protection, computation errors, or time-bar (where the assessment was raised outside the 6-year FIRS assessment limitation period). Each ground must be stated separately and with sufficient particularity for FIRS to evaluate.
Amount Admitted as Correct: Under Section 68(1) of CITA, the objection must state the amount the taxpayer admits to be correct tax. A taxpayer who objects to 100% of the assessment must still state that the correct amount of tax is zero, with reasons.
Request for Stay of Enforcement: Where applicable, a request that FIRS stay enforcement of the assessment (recovery of the disputed amount) pending determination of the objection and any subsequent TAT appeal, under the provisions of Section 68(3) of CITA.
Supporting Evidence: Audited financial statements, tax computations, board resolutions, intercompany agreements, transfer pricing documentation, DTA certificates of residence, WHT credit notes, and any other documents that support the grounds of objection. Attach all evidence to the letter as numbered exhibits.
Request for Meeting: Most FIRS objections are resolved through a negotiated settlement meeting between the taxpayer's tax advisers (typically CITN members or ICAN-qualified tax accountants) and the FIRS objection desk officer. A specific request for such a meeting within the body of the letter often supports faster resolution.

}Frequently Asked Questions
Under Section 68(1) of the Companies Income Tax Act (CITA), Cap C21, LFN 2004, a company that wishes to object to a FIRS tax assessment must file its written notice of objection within 30 days from the date of service of the assessment notice. For personal income tax assessments, Section 58(1) of the Personal Income Tax Act (PITA) 2011 provides the same 30-day objection window. If the 30-day deadline is missed, the assessment becomes final and conclusive under Section 68(4) of CITA, meaning the taxpayer loses the right to challenge the assessment. FIRS has a discretionary power under Section 68(6) to extend the objection period where the taxpayer shows reasonable cause for the delay — such as absence from Nigeria, serious illness, or non-receipt of the assessment notice — but extension is not guaranteed. Taxpayers should file an objection immediately upon receiving any FIRS assessment notice, even before fully evaluating the merits.
After receiving a timely objection letter, FIRS is required under Section 68(2) of the Companies Income Tax Act (CITA) to review the objection and either: (a) amend the assessment if satisfied that the objection is well-founded (issuing a revised assessment); or (b) refuse the objection (confirm the assessment as raised), notifying the taxpayer in writing. FIRS must issue its determination within a reasonable period, though there is no statutory deadline in CITA for FIRS to respond. In practice, FIRS typically invites the taxpayer for a review meeting (Objection Review Meeting) where the taxpayer's tax advisers and FIRS objection desk officers discuss the disputed items and negotiate a settlement. If no agreement is reached, FIRS issues a formal refusal notice. The taxpayer then has 30 days from the refusal notice to appeal to the Tax Appeal Tribunal (TAT) under Section 59 of the FIRSEA 2007.
Yes. If FIRS refuses a taxpayer's objection (confirms the assessment in whole or in part), the taxpayer may appeal to the Tax Appeal Tribunal (TAT) established under the Federal Inland Revenue Service (Establishment) Act 2007 (FIRSEA 2007) and the Tax Appeal Tribunal (Establishment, etc.) Order 2010. The TAT has nationwide jurisdiction through Zonal Benches (Lagos, Abuja, Port Harcourt, Kano, Benin, and Enugu). The taxpayer must file a TAT appeal within 30 days of receiving FIRS's refusal notice, accompanied by the TAT appeal form, the objection letter, the FIRS refusal notice, and the filing fee. The TAT hears appeals on both facts and law and may uphold, reduce, or discharge the assessment. An aggrieved party may further appeal from the TAT to the Federal High Court on a point of law only under Section 63 of the FIRSEA 2007.
Filing a FIRS objection letter does not automatically suspend FIRS's enforcement powers under Nigerian tax law. FIRS retains the legal authority to pursue recovery of the assessed tax while the objection is pending, including through distraint (seizure of assets) under Section 104 of CITA and demand notices under the FIRSEA 2007. However, in practice, FIRS typically refrains from aggressive enforcement while a formal objection is under review, particularly for large taxpayers with established tax agent relationships. A taxpayer seeking a formal stay of enforcement must apply specifically for a Restraining Order from the Tax Appeal Tribunal or, in urgent cases, an interlocutory injunction from the Federal High Court pending determination of the objection and appeal. The taxpayer may also offer to pay the undisputed portion of the assessment upfront to demonstrate good faith and reduce enforcement risk.
A best of judgment (BOJ) assessment in Nigeria is a tax assessment raised by the Federal Inland Revenue Service (FIRS) under Section 66 of the Companies Income Tax Act (CITA) where a company fails to file its self-assessment CIT return by the due date. In a BOJ assessment, FIRS estimates the company's taxable profits based on available information — prior year returns, industry benchmarks, public financial data, or FIRS's own assumptions — and raises an assessment on those estimated profits. BOJ assessments are frequently excessive because FIRS lacks access to the company's actual accounts. A company that receives a BOJ assessment may file a formal objection under Section 68 of CITA within 30 days, attaching the actual audited financial statements and tax computation to demonstrate the correct taxable profit and CIT liability. Filing the overdue tax return alongside the objection is strongly recommended to prevent FIRS from raising further BOJ assessments for subsequent years.
