VAT Audits and Assessments: What to Expect and How to Prepare.


Value Added Tax (VAT) is an integral part of Nigeria’s tax system, and it is crucial for businesses to understand their VAT compliance requirements. VAT audits and assessments are routine procedures conducted by tax authorities to ensure businesses are adhering to VAT regulations. As a reputable accounting firm in Nigeria, we aim to enlighten businesses on what to expect during a VAT audit or assessment and how to prepare effectively to ensure a smooth and successful process.

What is a VAT Audit and Assessment?

A VAT audit is an examination of a business’s VAT records, transactions, and compliance to verify the accuracy of VAT returns. Tax authorities perform these audits to ensure that businesses are correctly charging, collecting, and remitting VAT in line with the law.

On the other hand, a VAT assessment involves the tax authorities reviewing a business’s VAT records and calculations to determine if there are any discrepancies or underreported VAT liabilities. Based on the assessment, the tax authorities may issue a notice of assessment for additional VAT payment.

Reasons for VAT Audits and Assessments

VAT audits and assessments are conducted by tax authorities for various reasons, including:

a. Random Selection: Some businesses are selected randomly for audits to maintain compliance across all sectors.

b. Compliance Concerns: Tax authorities may conduct audits when they suspect non-compliance, errors, or irregularities in a business’s VAT reporting.

c. High-Value Transactions: Businesses engaged in high-value transactions may undergo audits to ensure proper VAT compliance.

d. Industry Focus: Tax authorities may focus on specific industries or sectors for targeted audits due to historical compliance issues.

What to Expect During a VAT Audit or Assessment

During a VAT audit or assessment, businesses can anticipate the following:

a. Request for Information: Tax authorities will request access to VAT records, invoices, receipts, and other relevant documentation.

b. Interview and Discussions: Tax officials may conduct interviews with key personnel to gain insights into VAT processes and practices.

c. Verification of VAT Returns: VAT returns will be cross-referenced with financial records to ensure accuracy and compliance.

d. Sampling: In large organizations, tax authorities may use sampling methods to assess compliance across a representative portion of transactions.

How to Prepare for a VAT Audit or Assessment

Effective preparation can streamline the VAT audit or assessment process and minimize disruptions to business operations. Businesses can follow these steps:

a. Organize VAT Records: Maintain well-organized VAT records, invoices, and supporting documents to facilitate easy access during the audit.

b. Review VAT Processes: Conduct an internal review of VAT processes and calculations to identify and address any potential compliance issues.
