What is Audit and Types of Audit

February 4, 2026 by CA Reema Negi

MEANING, OBJECTIVE OF AUDIT

Introduction

In today’s business environment, organizations carry out many financial transactions that affect investors, lenders, government authorities, and other stakeholders. These stakeholders rely on financial statements to make important economic decisions.

Therefore, it is essential that financial information is accurate and reliable. Audit helps in achieving this by independently examining financial records and statements. It increases the credibility of financial information and builds confidence among stakeholders.

 

Meaning and Definition of Audit

An audit refers to an independent examination of the financial information of any entity, whether profit-oriented or not, irrespective of its size or legal form, conducted with a view to expressing an opinion on such information.

In simple terms, audit involves a systematic verification of books of accounts, vouchers and supporting documents to determine whether financial statements present a true and fair view. Importantly, preparation of financial statements is the responsibility of management, whereas the auditor only examines and reports on them.

Nature of Audit

Furthermore, audit possesses certain essential characteristics:

  • Audit is independent, which ensures objectivity and unbiased judgment.
  • Audit examines historical financial information, not future performance.
  • Audit provides reasonable assurance to users of financial statements.
  • Audit concludes with a written audit report expressing the auditor’s opinion.

Thus, audit functions as an assurance mechanism that enhances the reliability and credibility of financial information.

Objectives of Audit

According to SA 200, the objectives of audit are clearly defined.

Primary Objective of Audit

First and foremost, the primary objective of audit is to obtain reasonable assurance that the financial statements as a whole are free from material misstatements, whether due to fraud or error. Consequently, this enables the auditor to express an opinion on whether the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework.

Secondary Objectives of Audit

In addition to the primary objective, audit also aims to:

  • Detect material errors and frauds
  • Examine the effectiveness of internal control systems
  • Ensure proper classification, presentation and disclosure of financial information
  • Safeguard the interests of shareholders and other stakeholders

Therefore, audit not only verifies figures but also promotes financial discipline and transparency.

Types of Audit

Audit can be classified into various types depending upon the purpose, nature and legal requirements.

  1. Statutory Audit

Statutory audit is compulsory under law. For example, companies are required to get their accounts audited under the Companies Act, 2013. The main objective of statutory audit is to ensure that financial statements comply with legal requirements and present a true and fair view.

  1. Internal Audit

Internal audit is conducted to assist management in improving operational efficiency. It evaluates internal controls, risk management systems and compliance with internal policies. Hence, internal audit acts as an important management tool.

  1. External Audit

External audit is conducted by an independent auditor to enhance confidence of users of financial statements. It provides reasonable assurance and strengthens trust among investors, lenders and regulators.

  1. Government Audit

Government audit examines receipts and expenditure of government departments and public sector undertakings. It ensures proper utilization of public funds and compliance with laws and regulations.

  1. Tax Audit

Tax audit is conducted to ensure compliance with taxation laws. It verifies correctness of income, proper maintenance of books of accounts and correct disclosure of tax-related information.

  1. Voluntary Audit

Voluntary audit is conducted even when there is no legal requirement. Many entities opt for voluntary audit to enhance credibility, strengthen internal controls and gain confidence of lenders.

  1. Special Audit

Special audit is conducted for a specific purpose, such as investigation into suspected fraud, verification ordered by regulators, or valuation-related examinations.

Thus, different types of audit serve different purposes, yet all contribute towards accountability and transparency.

Legal Provisions and Relevant Sections Related to Audit

Audit is governed by various statutory provisions that define its scope, applicability and authority.

  1. Companies Act, 2013
  • Section 139 – Appointment of Auditor
    Every company must appoint an auditor at its Annual General Meeting.
  • Section 141 – Eligibility and Qualifications of Auditor
    This section ensures auditor independence by specifying qualifications and disqualifications.
  • Section 143 – Powers and Duties of Auditor
    This section grants auditors the right to access books of accounts, seek information and explanations, and report on the true and fair view of financial statements.
  • Section 143(3) – Audit Report
    This subsection specifies mandatory matters to be included in the audit report.
  1. Income-tax Act, 1961
  • Section 44AB – Tax Audit
    This section mandates tax audit for specified persons to ensure correct computation of income and compliance with tax laws.
  1. Government Audit (CAG Audit)

Audit of government bodies and public sector undertakings is conducted under the authority of the Comptroller and Auditor General of India to ensure accountability in public finance.

  1. Voluntary Audit – Legal Recognition

Law permits voluntary audit even where it is not compulsory. Such audits enhance credibility and financial discipline.

Advantages of Audit of Financial Statements

Now let us examine the advantages of audit in detail.

  1. Provides High-Quality Financial Information

Audit ensures that financial statements comply with accounting standards and legal requirements. As a result, users receive reliable and high-quality financial information.

  1. Enhances Confidence of Users

Audited financial statements enhance confidence of shareholders, investors, lenders and regulators. Consequently, users can rely on audited information for decision-making.

  1. Safeguards Interests of Shareholders

Since shareholders do not participate in day-to-day management, audit acts as an independent mechanism to protect their interests.

  1. Acts as a Moral Check on Employees

Audit discourages fraud and errors due to fear of detection. Hence, it promotes honesty and discipline within the organization.

  1. Assists Government Authorities

Audited accounts help government authorities in determining correct tax liabilities and ensuring compliance with laws.

  1. Helps Banks and Financial Institutions

Banks and financial institutions rely on audited financial statements while granting loans and credit facilities. Therefore, audit facilitates access to finance.

  1. Detection of Errors and Frauds

Although not the primary objective, audit may detect errors and frauds during examination of accounts.

  1. Improves Internal Control System

Audit evaluates internal controls and highlights weaknesses. As a result, management can take corrective measures.

  1. Enhances Overall Financial Discipline

Audit encourages proper maintenance of books of accounts, adherence to accounting principles and timely preparation of financial statements.

Conclusion

In conclusion, audit plays an important role in ensuring transparency, accountability, and trust in financial reporting. By independently examining financial information, it provides assurance to stakeholders and helps them make informed decisions. Different types of audit and legal provisions ensure its wide use, making audit an essential part of a reliable and efficient financial system.
