Preparing a Business for External Audits in Nigeria

For many business owners in Nigeria, the words “external audit” trigger anxiety. They imagine endless queries, piles of documents, and the uncomfortable feeling of being scrutinised. So they delay, procrastinate, and hope the auditors will go away.

But here is the truth: an external audit is not a punishment. It is an independent review of your company’s financial records and statements, carried out by a licensed auditor, to confirm that the financial information presented is accurate, complete, and compliant with regulatory standards. When approached strategically, it becomes a tool for strengthening your business, not a threat to it.

Statutory audits in Nigeria are primarily governed by the Companies and Allied Matters Act 2020 (CAMA 2020), the Financial Reporting Council of Nigeria Act 2011 (as amended), and the Investments and Securities Act 2007. Under CAMA 2020, all companies must be audited annually, except small companies that meet specific revenue, asset, and employee thresholds for two consecutive years.

This guide covers everything you need to know about preparing your business for an external audit in Nigeria—and the common pitfalls to avoid.

The Pain Points: Why Businesses Struggle with External Audits

Let us be honest. Most business owners know they should be audit-ready, but they are not. Here is why:

The “We Will Deal With It Later” Trap. When you are focused on running your business, preparing for an audit always seems like something you can do later. But later never comes—until the auditors arrive and you are scrambling to find receipts, reconcile accounts, and explain discrepancies.

The Record-Keeping Gap. Many businesses do not maintain accurate, up-to-date financial records throughout the year. They file receipts in boxes, track expenses on scraps of paper, and rely on memory for critical transactions. When audit season comes, they simply do not have the documentation they need.

The Knowledge Gap. Many business owners do not understand what an audit entails or what auditors are looking for. They do not know their obligations under CAMA 2020, the requirements for financial reporting, or the standards that govern audits in Nigeria. This lack of understanding leads to anxiety and poor preparation.

The “We Are Too Small” Fallacy. Many small business owners believe that audits are only for large corporations. They do not realise that even where exemptions apply, banks, investors, and regulators often still require audited accounts.

The Fear of Discovery. Some business owners worry that an audit will uncover problems—errors, omissions, or even fraud. This fear leads them to avoid preparation, which only makes the audit more difficult.

The Cost Concern. Many businesses view the cost of an audit as an unnecessary expense. They do not recognise that the cost of non-compliance—in penalties, lost opportunities, and damaged reputation—is far higher.

The Auditor Verification Trap. A critical risk that many businesses miss: an engagement conducted by an unregistered audit firm is invalid under Nigerian law. If the firm that audited your accounts is not on the Financial Reporting Council’s Register, your business—not just the firm—is exposed to sanctions. The FRC has mandated that all statutory audit firms must register or update their regulatory profiles, and reporting entities are required to verify the registration status of both the audit firm and the signing audit professional before appointment.

These pain points are real, but they are not insurmountable. With the right preparation and the right support, you can transform the audit experience from a source of anxiety into a strategic advantage.

Understanding the Legal Framework

Who Must Be Audited?

Under CAMA 2020, the following entities must be audited annually:

Public companies – always required to be audited

Regulated entities – banking, insurance, pensions, and other regulated sectors

Companies exceeding small-company thresholds – even if you qualify for exemption, banks, investors, and regulators often still require audited accounts

Small companies that meet specific revenue, asset, and employee thresholds for two consecutive years may be exempt from the mandatory audit requirement. However, even where exemptions apply, audited accounts are often still required by lenders, investors, and business partners.

The Audit Committee

For Public Limited Liability Companies (PLCs), Nigerian law mandates the constitution of an audit committee comprising five members—three shareholders and two non-executive directors. This requirement underscores the importance of oversight in financial reporting and governance.

One of the most significant enhancements in CAMA 2020 is the requirement that at least one member of the audit committee must be a professional accountant. This provision ensures that the committee has the technical competence to interpret financial data, promote financial independence, and enhance audit supervision.

The audit committee plays a vital role in the appointment and remuneration of external auditors, ensuring the process is both transparent and objective.

The Financial Reporting Council (FRC) and Rule 14

The Financial Reporting Council of Nigeria (FRCN) introduced Rule 14 on Non-Compliance with Laws and Regulation to ensure that external auditors support corporate entities to promote a culture of compliance with laws, regulations, codes, rules and guidelines that may have direct or indirect impact on financial statements and operations.

Compliance with Rule 14 is a mandatory requirement for external auditors engaged in the audit of financial statements of public interest entities. External auditors are now obligated to confirm the compliance of corporate entities with relevant laws, rules, and regulations.

In practice, external auditors are now required to send a confirmation request to the FRCN prior to providing their audit opinion on a public interest entity’s financial statement. Upon receipt of a positive compliance confirmation from the FRCN, the external auditor proceeds to issue their audit opinion. In the event of a negative compliance confirmation, the company is required to rectify the identified non-compliance issue(s) before the external auditor can resubmit a confirmation request.

Auditor Appointment and Independence

Auditors are appointed at the annual general meeting of a company. Those eligible to be appointed as external auditors are generally Chartered Accountants who are members of the Institute of Chartered Accountants of Nigeria (ICAN) or members of the Association of National Accountants of Nigeria (ANAN).

The Nigerian Code of Corporate Governance 2018 provides that external audit firms may be retained for no longer than ten years continuously and may not be considered for reappointment until after a seven-year cooling-off period. Auditors are required to be independent in the performance of audit activities, such that their professional judgement is unbiased.

The FRC Register of Audit Firms

The FRC has introduced a new registration regime for all statutory audit firms and other assurance service-providing firms. Under this new framework, only firms on the Register will be permitted to undertake, accept, or continue audit or assurance engagements in Nigeria. Reporting entities are required to verify the registration status of both the audit firm and the signing audit professional prior to appointment and throughout the duration of any engagement, as the Register is reopened annually.

Step-by-Step Guide to Preparing for an External Audit

Step 1: Understand Your Audit Obligations

The first step in audit preparation is knowing what is required of your business. Determine whether your business is required to be audited under CAMA 2020. If you are a small company that qualifies for exemption, understand that banks, investors, and regulators often still require audited accounts.

Understand the standards that govern audits in Nigeria. Financial statements are required to comply with the requirements of CAMA 2020 and the accounting standards laid down in the statements of accounting standards issued by the Financial Reporting Council of Nigeria.

Pain Point: Many businesses are simply unaware of their audit obligations. They assume that because they are small, they do not need to be audited. This assumption can be costly.

Step 2: Appoint a Qualified, Independent Auditor

Engage a qualified, independent auditor who is compliant with ICAN and FRC requirements. Ensure that both the audit firm and the signing audit professional are registered with the FRC. Remember: an engagement conducted by an unregistered firm is invalid under Nigerian law, and your business—not just the firm—is exposed to sanctions.

Pain Point: Many businesses appoint auditors without verifying their registration status. This exposes the business to significant legal and regulatory risk.

Step 3: Maintain Accurate Financial Records Throughout the Year

The most effective way to prepare for an audit is to maintain accurate financial records throughout the year—not just when the auditors arrive. This means:

Recording all financial transactions promptly and accurately

Keeping receipts, invoices, and supporting documentation

Reconciling bank accounts monthly

Maintaining proper books of account

Ensuring that financial records are complete and up to date

Pain Point: Many businesses keep records that are incomplete, inaccurate, or disorganised. When auditors arrive, they spend valuable time—and money—reconstructing records that should have been maintained properly.

Step 4: Organise Your Documentation

Before the audit begins, ensure that all documentation is organised and accessible. Key documents include:

Financial statements for the fiscal year

Documentation of income, expenses, and financial activities

Invoices, receipts, and payment proofs

Bank statements and reconciliations

Payroll records and employee contracts

Tax returns and payment receipts

Contracts and agreements

Board minutes and resolutions

Statutory registers (directors, shareholders, beneficial owners)

Certificate of Incorporation and Memorandum and Articles of Association

Pain Point: Many businesses have documentation scattered across notebooks, spreadsheets, emails, and memory. Without a centralised system, documents are difficult to access when auditors need them.

Step 5: Review and Reconcile Your Accounts

Before the auditors arrive, conduct an internal review of your accounts. This includes:

Ensuring that all transactions have been recorded

Reconciling all accounts

Identifying and correcting errors

Reviewing internal controls and financial processes

Ensuring compliance with CAMA 2020

Pain Point: Many businesses wait until the auditors arrive to review their accounts. This reactive approach leads to delays, additional costs, and a more stressful audit experience.

Step 6: Prepare for the Audit Process

The audit process typically follows these steps:

Appointment of a qualified, independent auditor – ICAN and FRC compliant
Review of financial records and internal controls – The auditor examines your records to verify accuracy and completeness

Issuance of an audit opinion – The auditor issues one of four opinions:

Clean opinion – The financial statements present a true and fair view

Qualified opinion – There are exceptions or limitations

Adverse opinion – The financial statements do not present a true and fair view

Disclaimer of opinion – The auditor cannot form an opinion

Filing audited accounts with the CAC – The audited financial statements must be filed with the Corporate Affairs Commission

Pain Point: Many business owners do not understand the audit process and are caught off guard by what auditors require. Understanding the process in advance reduces anxiety and improves preparation.

Step 7: Factor in FRC Confirmation Timeline

If your business is a public interest entity, factor in the timeline for obtaining a confirmation request from the FRCN. External auditors are now required to send a confirmation request to the FRCN prior to providing their audit opinion. The typical processing time frame for this procedure is two weeks, though it may vary depending on the volume of requests received by the FRCN.

Pain Point: Failure to factor in this timeline can cause significant delays in the audit process.

Step 8: File Audited Accounts with the CAC

Once the audit is complete, ensure that the audited financial statements are filed with the Corporate Affairs Commission. Failure to comply can lead to fines and regulatory sanctions, inability to file annual returns, and loss of investor and lender confidence.

Pain Point: Many businesses complete the audit but fail to file the audited accounts with the CAC. This exposes them to penalties and compliance issues.

Common Audit Challenges and How to Overcome Them

Improper Bookkeeping

Improper bookkeeping by clients’ staff constitutes a major setback to external auditors’ job. When your records are not properly maintained, the audit process becomes longer, more expensive, and more stressful.

Solution: Invest in proper bookkeeping throughout the year. Use accounting software or engage professional bookkeepers to ensure your records are accurate and up to date.

Inadequate Expertise

Many SMEs still face challenges such as inadequate expertise, high cost of professional services, poor record-keeping culture, and weak regulatory enforcement.

Solution: Engage qualified professionals who understand Nigerian accounting standards and regulatory requirements. Invest in training for your finance team.

Mixing Personal and Business Finances

One of the most common and costly mistakes is mixing personal and business finances. This makes it difficult to track business transactions, complicates the audit process, and creates legal and tax risks.

Solution: Open a separate business bank account and use it exclusively for business transactions.

Incomplete Expense Documentation

Incomplete expense documentation is a major challenge during audits. Without proper receipts and supporting documentation, expenses cannot be verified.

Solution: Implement a system for capturing and storing expense documentation. Use scanning apps to digitise receipts immediately.

The Risk of Unregistered Auditors

Nigerian businesses are exposed to sanctions for engaging unregistered auditors. An engagement conducted by an unregistered firm is invalid under Nigerian law.

Solution: Verify the registration status of both the audit firm and the signing audit professional before appointment. Check the FRC Register to confirm that the firm and individual are properly registered.
