AUDIT READINESS GUIDE FOR AUDITEES

Introduction

Audit readiness begins well before the audit period ends. Or so it should . For many Nigerian businesses, preparing for an audit can feel like a sudden, overwhelming event. Yet, when organizations embrace audit readiness as a year-round discipline, it reinforces trust, drives operational clarity, and reduces year-end stress .

As Nigeria’s business landscape becomes more regulated and technology-driven, organizations are facing increasing pressure to strengthen their internal controls . Regulatory reforms, digital tax administration, and heightened stakeholder expectations mean that year-end audits are no longer simply about producing compliant financial statements—they are about demonstrating that a business is well-governed, resilient, and prepared for scrutiny .

This comprehensive guide provides a practical framework for auditees to achieve and maintain audit readiness, covering everything from building a document file to understanding the audit process and responding to auditor inquiries.

The Pain Points: Why Businesses Struggle with Audit Preparation

Many organizations still approach audit preparation a few weeks before their auditors arrive, which often results in avoidable delays, increased audit costs, and the discovery of control weaknesses that could have been addressed much earlier . The reactive approach creates stress across departments and can damage credibility with stakeholders.

Common Challenges Faced by Auditees

• Weak Documentation: Transactions may be properly recorded but lack adequate supporting documentation such as contracts, approvals, invoices, or payment evidence .

• Poor Segregation of Duties: One individual may initiate, approve, and record transactions, increasing the risk of fraud and error .

• Ineffective Reconciliations: Delayed or incomplete bank, inventory, and account reconciliations often lead to financial reporting errors .

• Inadequate IT Controls: As businesses rely more heavily on cloud-based systems and digital platforms, weak access controls and insufficient cybersecurity measures expose organizations to operational risks .

• Delayed Financial Close: Incomplete reconciliations and poor coordination between departments often extend the audit timeline and increase audit costs .

The Consequences of Poor Audit Readiness

Without proper preparation, organizations may face:

• Increased audit costs due to delays and adjustments

• Timely issuance of final reports being compromised

• Damage to investor, lender, and regulator confidence

• Discovery of control weaknesses that could have been addressed earlier

• Late filing penalties under the new tax regime, which have increased to N100,000 in the first month

What Is Audit Readiness?

Audit readiness is the process of ensuring that an organization’s financial records, supporting documentation, internal controls, and governance processes are accurate, complete, and available before the audit begins .

The Three Phases of an Audit

The audit process typically unfolds in three main phases :

1. Planning Phase: Auditors assess your organization’s risk factors and establish an audit plan tailored to your specific circumstances

2. Fieldwork Phase: Auditors gather evidence through testing and reviewing your financial records

3. Reporting Phase: The audit process culminates in the auditors issuing a report detailing their findings and opinions

Step 1: Build Your Audit File Throughout the Year

Instead of waiting for a letter, build your tax file as you go . This is the most effective way to ensure you are audit-ready when the auditors arrive.

What to Include in Your Audit File

Financial Statements and Tax Records:

• Audited accounts for each year

• Tax computations and capital allowance schedules

• All tax returns and payment receipts for that year

• Detailed revenue schedules (monthly/annual) tied to the trial balance

Revenue and Sales Documentation:

• Customer invoices and receipts (numbered and dated)

• Contracts, LPOs, and engagement letters with clients

• Evidence of cash receipts and POS/transfer confirmations

• VAT output schedules (showing VAT collected per invoice)

The “Golden Rule”

The key is that the total sales in your financial statements must match your VAT schedules, WHT records, and bank lodgements, barring clearly explained differences . VAT, WHT, and your ledgers must agree, or you should be able to explain every variance clearly .

Step 2: Organize Expense, Procurement, and Supplier Documentation

Tax authorities want to verify that your expenses are genuine, business-related, and correctly treated for tax .

Required Documentation

• Detailed expense schedules by nature (rent, salaries, fuel, professional fees, etc.)

• Supplier invoices and receipts

• Payment vouchers and approvals

• Contracts/agreements with vendors and consultants

• Evidence of payment (bank transfers, cheques, etc.)

• WHT deducted on vendor payments and proof of remittance

Watch Out For

• Excessive “miscellaneous” or “sundry” expenses without backing

• Large cash withdrawals without proper supporting documentation

• Director or shareholder personal expenses run through the company

Fixed Assets and Capital Allowances

Auditors want to ensure your capital allowance claims are not inflated . Maintain:

• Fixed asset register with asset description, location, cost, dates, and depreciation

• Invoices and receipts for asset purchases

• Evidence of disposal (board approvals, sale agreements, proceeds)

• Capital allowance computations and schedules used in your CIT returns

Step 3: Maintain Payroll, PAYE, and HR Records

The NRS pays close attention to payroll . Ensure you have:

• Staff list for each year (name, role, start/end dates)

• Employment contracts and HR policies

• Monthly payroll schedules (gross pay, allowances, deductions, PAYE, pension)

• Payslips and signed payroll summaries

• PAYE computation workings and annual returns

• Proof of PAYE remittances for each month

• Pension schedules and evidence of remittance

• NSITF, ITF, and other statutory HR-related payments, where applicable

Step 4: Document Related Party, Loans, and Equity Transactions

Cross‑border and related party transactions are more sensitive now . Prepare:

• Intercompany loan agreements, shareholder loan terms, and board approvals

• Transfer pricing documentation (for medium/large businesses with related party dealings)

• Interest computation schedules and evidence of payment

• Dividend payment schedules, withholding tax remittances, and board resolutions

Step 5: Prepare Your Internal Audit Team

Auditors get nervous when nobody seems to own anything in an organisation . Establish an audit response team with at least:

• A tax lead (CFO, finance manager, or external adviser)

• A documentation officer who can locate documents quickly

• A legal/company secretary representative

Assemble a Cross-Functional Team

It is essential to assemble a dedicated, cross-functional audit team within your organization comprising key personnel from finance, accounting, compliance, and operations. Appointing a project manager to coordinate the audit process can streamline communication and ensure that all team members understand their roles and responsibilities .

Step 6: Strengthen Internal Controls

A robust control environment is critical for establishing effective internal controls . It encompasses the integrity, ethical values, and overall culture of your organization.

Questions Every Board Should Be Asking

Executive leadership should periodically consider :

• Are our financial controls operating effectively?

• Are significant risks identified and monitored?

• Can we support every material transaction with reliable documentation?

• Have we assessed emerging cyber and technology risks?

• Are we prepared for increased regulatory scrutiny?

Key Controls to Review

• Segregation of Duties: Ensure that no single individual initiates, approves, and records transactions

• Approval Hierarchies: Establish clear approval hierarchies with a delegation of authority policy

• Reconciliations: Complete all account reconciliations monthly

• IT Controls: Review user access to financial systems and cybersecurity measures

Step 7: Conduct a Self-Audit

At least once a year (preferably before filing CIT returns) :

• Reconcile revenue per financial statements with VAT and WHT schedules

• Reconcile payroll records with PAYE and pension submissions

• Recompute your tax using the applicable legislation to ensure nothing has been missed

Many assessment disputes come from simple things like unremitted WHT or PAYE, or unreconciled differences the company never cleaned up .

Step 8: Engage a Qualified Auditor

Choosing the Right Auditor

Startups are well aware that audited financial statements are an essential component of their data rooms and one of the major documents on the investment readiness checklist .

Issuing a letter appointing an auditor is a lot like a “marriage proposal”—once it is accepted by the NRS, that auditor is officially part of your business journey . This decision matters. You are trusting someone with your business performance, your bank statements, your investment details, and all your financial “skeletons” .

Key Requirements:

• Auditors must be Chartered Accountants who are members of ICAN or ANAN

• All statutory audit firms must be registered with the Financial Reporting Council (FRC)

• Engaging an unregistered auditor exposes businesses to sanctions; the engagement is invalid under Nigerian law

Step 9: Prepare for Fieldwork

Before the Audit Begins

Before fieldwork officially begins, auditors will typically issue a detailed preparation checklist with deadlines. This request list becomes the guiding framework for the engagement .

The audit request list typically includes:

• Trial balance

• All supporting reconciliations

• Administrative items

Organizations should aim to upload documentation electronically via a secure portal—not email—to protect sensitive information and maintain an organized record of the audit trail .

Planning Meeting

Before the audit begins, the auditors and key management staff should hold a planning meeting to address significant items not yet covered throughout the year . This may include:

• Starting or closing a major program

• Receiving a large grant or donation

• Initiating significant leases or long-term contracts

• Adopting a new accounting, payroll, or billing system

• Leadership transitions or organizational restructuring

• Legal matters, including litigation or suspected fraud

Questions from Auditors

During preliminary fieldwork, auditors focus on understanding internal controls and conducting walkthroughs. They will also ask IT-related questions :

• What systems house financial data?

• How is data backed up?

• Have there been any security breaches?

• How are user access rights managed?

• Is there a defined risk management process?

Step 10: Handle Auditor Inquiries Professionally

Be Prepared, Responsive, and Transparent

A successful audit requires being responsive and being prepared . Consult with your auditor in the event of :

• Being unsure of how to record a transaction

• Infrequent or unusual transactions

• A new legal entity or controlled organization

• A merger

• Actual or suspected fraud

• Pending or threatened litigation

Key Tips for Handling Inquiries

1. Designate an individual responsible for the management of the audit to ensure the timeliness of management responses and communications with the auditor

2. Establish open lines of communication with your audit firm. Discuss the audit timeline, expectations, and any specific areas of focus with the auditors

3. Document management decision points clearly. The more forthcoming and clear about your decisions and the reasons for making them, the less back and forth you will need

Common Audit Pitfalls and How to Avoid Them

1. 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 .

2. 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 .

3. 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 .

4. Engaging Unregistered Auditors

Nigerian businesses are exposed to sanctions for engaging unregistered auditors .

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 .
