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

Assessments' Under Income Tax Act. 1961


In Nigeria, as in many countries, tax compliance is a crucial aspect of doing business. The Companies Income Tax (CIT) Act places responsibilities on companies to accurately report their income and pay the appropriate taxes. To ensure compliance, tax authorities conduct assessments and audits of businesses. Understanding what to expect during these processes and how to prepare for them is essential for companies to maintain a good standing with tax authorities. In this article, we will delve into what to expect during these processes and how businesses can prepare effectively.

CIT Assessments vs. Audits:

Before we dive into the details, it’s important to distinguish between CIT assessments and audits:

  1. Assessments: Assessments are a routine part of the tax collection process. Tax authorities review the tax returns submitted by companies to ensure accuracy and completeness. If discrepancies or errors are identified, the tax authority issues an assessment notice to the company, outlining the adjustments required.
  2. Audits: Audits are more extensive and involve a comprehensive review of a company’s financial records and tax returns. Audits are typically triggered by specific concerns, red flags, or random selection. They can be more in-depth and may require additional documentation and explanations from the company.

What to Expect During CIT Assessments and Audits:

  1. Notification: Companies selected for an assessment or audit will receive official notification from the tax authorities. This notice will outline the scope, purpose, and expected duration of the process.
  2. Document Requests: During audits, tax authorities will request various documents, including financial records, tax returns, bank statements, and supporting documents for deductions and credits claimed.
  3. Interviews and Inquiries: Tax officials may conduct interviews with company representatives to gather additional information and clarify discrepancies.
  4. On-Site Visits: In some cases, tax authorities may conduct on-site visits to inspect physical assets and operations.
  5. Assessment or Audit Report: Following the assessment or audit, tax authorities will issue a report outlining their findings, adjustments, and any additional tax liabilities.

How to Prepare for CIT Assessments and Audits:

  1. Document Retention: Maintain accurate and organized records of financial transactions, tax returns, and supporting documents. Proper documentation is essential to substantiate claims and deductions.
  2. Regular Reconciliation: Conduct regular reconciliations of financial records to ensure they align with tax returns.
  3. Compliance with CIT Act: Ensure compliance with all provisions of the CIT Act, including reporting and payment deadlines.
  4. Engage Tax Professionals: Seek the assistance of tax experts who can provide guidance and support during assessments and audits.
  5. Open Communication: Establish open and transparent communication with tax authorities. Respond promptly to requests for information and documentation.
  6. Appeal Rights: Be aware of your rights to appeal any adverse findings or assessments.


CIT assessments and audits are standard procedures in ensuring tax compliance in Nigeria. Companies should be prepared to cooperate with tax authorities and provide accurate and complete information. Maintaining meticulous records, complying with tax laws, and seeking professional guidance are key strategies to ensure a smooth process during assessments and audits.
