Audit Requirements for Companies in Nigeria

Audit Requirements for Companies in Nigeria (2026 Updated Guide Under CAMA)

Understanding audit requirements in Nigeria is critical for every registered company. With evolving corporate governance standards and regulatory enforcement, businesses must know whether they are legally required to conduct a statutory audit — and what exemptions apply.

This guide explains audit requirements under the Companies and Allied Matters Act (CAMA), small company exemptions, regulatory expectations, and practical compliance considerations in 2026.

What Is a Statutory Audit?

A statutory audit is an independent examination of a company’s financial statements conducted by a licensed external auditor to ensure that the accounts present a true and fair view of the company’s financial position.

In Nigeria, statutory audits are governed primarily by:

• Corporate Affairs Commission (CAC)
• Financial Reporting Council of Nigeria (FRCN)
• The Companies and Allied Matters Act (CAMA 2020 as amended)

Who Is Required to Conduct an Audit in Nigeria?

Under CAMA, all companies must appoint an external auditor, except those that qualify as “small companies” and meet specific exemption criteria.

Small Company Audit Exemption (CAMA Provision)

A company may be exempt from statutory audit if it qualifies as a small company and meets all of the following conditions:

1. Annual turnover not exceeding ₦120 million
2. Net assets not exceeding ₦60 million
3. No foreign shareholder
4. Directors hold at least 51% equity
5. Not part of a group of companies

⚠️ Important: Even if exempt from audit, the company must still:

• Maintain proper accounting records
• Prepare annual financial statements
• File annual returns with CAC
• Comply with tax filing requirements

Companies That Must Conduct a Statutory Audit

The following must appoint an external auditor:

• Medium and large companies
• Companies with foreign ownership
• Public companies (PLC)
• Companies operating in regulated industries
• NGOs and incorporated trustees (subject to regulatory oversight)
• Subsidiaries of foreign entities

Additionally, regulatory agencies such as:

• Central Bank of Nigeria (CBN)
• Securities and Exchange Commission (SEC)
• National Insurance Commission (NAICOM)

may impose stricter audit requirements for financial institutions and regulated sectors.

When Must an Auditor Be Appointed?

• The first auditor may be appointed by the directors within 30 days of incorporation.
• Subsequent auditors are appointed at the Annual General Meeting (AGM).

Failure to appoint an auditor when required may attract penalties and regulatory sanctions.

What Does an External Auditor Do?

A statutory auditor will:

✔ Examine accounting records
✔ Verify assets and liabilities
✔ Review internal controls
✔ Test compliance with accounting standards
✔ Express an independent audit opinion

Audit opinions may be:

• Unqualified (clean opinion)
• Qualified
• Adverse
• Disclaimer

Financial Reporting Standards in Nigeria

Audits in Nigeria must comply with standards issued by the Financial Reporting Council of Nigeria (FRCN).

Applicable frameworks include:

• IFRS (for public interest entities)
• IFRS for SMEs
• Relevant Nigerian auditing standards

Non-compliance may result in financial statement rejection or regulatory penalties.

Filing Audited Financial Statements

Companies required to audit must:

• Attach audited financial statements to annual returns
• File with CAC
• Submit tax returns to the Nigeria Revenue Service

Failure to file audited accounts can result in:

• Late filing penalties
• Director liability exposure
• Inability to secure loans or contracts

Benefits of Conducting an Audit (Even If Exempt)

Even where audit exemption applies, voluntary audit provides:

✔ Increased credibility
✔ Improved investor confidence
✔ Stronger internal controls
✔ Fraud detection
✔ Better access to financing
✔ Improved corporate governance

Banks and investors often request audited financial statements before granting funding.

Audit vs Internal Audit: What’s the Difference?

Both play different but complementary roles in corporate governance.

Common Audit Compliance Mistakes

❌ Not appointing an auditor when required
❌ Late annual return filing
❌ Poor record-keeping
❌ Mixing personal and company transactions
❌ Inadequate internal controls

These often lead to qualified audit opinions or regulatory scrutiny.

Penalties for Non-Compliance

Under CAMA, failure to comply with audit requirements may result in:

• Monetary fines
• Director sanctions
• Restrictions on company operations
• Legal enforcement actions

Regulatory enforcement is increasing, especially for companies seeking government contracts or external funding.
