In India, audits are essential processes to ensure transparency, accuracy, and compliance with various legal, tax, and regulatory frameworks. Depending on their purpose and scope, audits can be categorized into several types under the Companies Act, 2013, and other Indian laws.​

Major Types of Audits in India

1. Statutory Audit

A statutory audit is mandatory for all companies, regardless of size or turnover. Conducted by a Chartered Accountant, it assesses whether the company’s financial statements present a true and fair view of its financial position. This ensures compliance with the Companies Act and accounting standards. The audit report is submitted to shareholders and regulators.​

2. Internal Audit

Internal audits evaluate the operational efficiency, internal controls, and risk management systems of a company. They are required for listed and large unlisted companies meeting specified thresholds of turnover, capital, or borrowings. The findings are reported to the company’s management to strengthen internal governance.​

3. Tax Audit

Under Section 44AB of the Income Tax Act, 1961, a tax audit is mandatory for businesses with turnover exceeding ₹1 crore (or ₹10 crore if 95% of transactions are digital). It ensures proper maintenance of tax records and accurate assessment of income, deductions, and returns to prevent evasion.​

4. Cost Audit

A cost audit applies primarily to manufacturing and production-based industries. Conducted by a Cost Accountant, it verifies cost accounting records, production efficiency, and adherence to government-notified standards. This promotes transparency in pricing and cost control mechanisms.​

5. Secretarial Audit

Secretarial audits, performed by a Practicing Company Secretary (PCS), examine compliance with corporate governance and legal frameworks, including SEBI, the Companies Act, and Listing Regulations. This audit is mandatory for listed companies and large public corporations.​

6. GST Audit

Applicable to companies with turnover exceeding ₹5 crore, a GST audit reconciles financial statements with GST returns to ensure accurate tax reporting and claim of Input Tax Credit (ITC). The reconciliation is filed using Form GSTR-9C.​

Optional or Specialized Audits

  • Forensic Audit: Investigates fraud, embezzlement, or financial mismanagement.
  • Compliance Audit: Ensures adherence to statutory and regulatory obligations.
  • Environmental Audit: Reviews operational impact on the environment and sustainability reporting.
  • Information Systems Audit: Examines IT controls, data security, and system integrity.​

Each audit type contributes to maintaining financial discipline, operational reliability, and investor confidence across corporate entities.
