Quick Answer: Is Company Audit Mandatory in India?

Yes, as a general rule, companies incorporated under the Companies Act, 2013 are required to have their financial statements audited by a statutory auditor every financial year. The requirement generally applies to private companies, public companies and other company forms, although additional audit-related requirements and exemptions can differ depending on the company's nature, size, activities and applicable regulations.

A statutory audit should not be confused with a tax audit. Statutory audit requirements arise under company law, while tax audit requirements arise under income-tax legislation when the applicable conditions are satisfied.

Therefore, a company should determine separately whether statutory audit, tax audit, CARO reporting, internal audit or any other specialised audit requirement applies to it.

1. What Is a Company Audit?

A company audit is an independent examination of a company's financial statements, books of account, accounting records and related financial information by a qualified auditor.

The purpose of an audit is to provide an independent opinion on whether the financial statements present a true and fair view in accordance with the applicable financial reporting framework and legal requirements.

An auditor may review transactions, supporting documents, accounting policies, balances, internal controls, statutory records and other relevant information while carrying out the audit.

2. Is Audit Mandatory for All Companies in India?

The general answer is yes. Under the Companies Act, 2013, companies are subject to statutory audit requirements. Section 139 provides for the appointment of an auditor for a company, and the audit provisions contained in Chapter X apply to companies covered by the Act.

This means that a company does not normally become exempt from statutory audit merely because:

• its turnover is low;
• it has no major business activity;
• it incurred a loss;
• it had no revenue during the year; or
• it is classified as a small company or OPC.

However, companies may receive certain relaxations under particular provisions, rules or reporting requirements. These relaxations should not automatically be interpreted as a complete exemption from statutory audit.

3. Legal Framework for Company Audit

The Companies Act, 2013 provides the primary legal framework for statutory audits of companies in India. Some of the important provisions are discussed below.

Section 139 – Appointment of Auditors

Section 139 deals with the appointment of auditors. It provides for appointment of an individual or a firm as auditor, subject to the applicable provisions of the Companies Act.

The appointment framework is therefore a central part of annual audit compliance for companies.

Section 143 – Powers and Duties of Auditors

Section 143 sets out important powers and duties of auditors. These include rights to access books and accounts and requirements concerning the auditor's report.

An auditor may require information and explanations considered necessary for performing the audit and forming the audit opinion.

Section 138 – Internal Audit

Internal audit is different from statutory audit. Section 138 provides that prescribed classes of companies are required to appoint an internal auditor to conduct an internal audit of the functions and activities of the company.

Therefore, internal audit should be evaluated independently based on the company's category and applicable rules.

4. Is Audit Mandatory for a Private Limited Company?

Yes. A private limited company is generally required to have its annual financial statements audited by a statutory auditor.

This requirement generally applies even when the company is relatively small or has limited transactions during the financial year.

A common misconception among startup founders is that audit becomes mandatory only after crossing a particular turnover threshold. That concept primarily relates to certain tax-audit requirements, not the basic statutory audit obligation of a company under company law.

For example, a private company may have modest revenue but still need to complete its statutory audit, prepare its financial statements and comply with the relevant filing requirements.

5. Is Audit Mandatory for a Small Company?

A small company may qualify for certain regulatory relaxations under the Companies Act and applicable rules. However, being classified as a small company does not by itself mean that the company is completely free from statutory audit requirements.

It is important to distinguish between simplified financial reporting or other compliance concessions and the statutory audit requirement.

↑ Back to Table of Contents

6. Is Audit Mandatory for an OPC?

An One Person Company (OPC) is still a company incorporated under the Companies Act. Therefore, an OPC generally remains subject to statutory audit requirements.

OPCs can receive certain compliance relaxations depending on the relevant provisions, but these should not be interpreted as removing the statutory audit obligation unless a specific law or applicable exemption clearly provides otherwise.

7. Does a Dormant Company Need an Audit?

Dormant companies may have very limited activity, but dormant status should not automatically be assumed to remove all audit and financial compliance requirements.

The company should examine the conditions attached to its dormant status and the specific compliance obligations applicable to that status.

If the company continues to have statutory filing and financial statement obligations, professional advice should be taken before assuming that no audit is required.

8. Different Types of Audit for Companies

The word "audit" can refer to different compliance requirements. The following distinctions are important for business owners.

Statutory Audit

Statutory audit is the annual audit of the company's financial statements under company law. It is conducted by the company's appointed statutory auditor.

Tax Audit

Tax audit is an audit requirement under income-tax legislation when the prescribed conditions are satisfied. It is not the same as the statutory audit carried out under the Companies Act.

The Income Tax Department currently identifies the tax-audit requirement under section 44AB of the Income-tax Act, 1961 for the relevant transition period and section 63 of the Income Tax Act, 2025 for the new tax regime framework.

CARO

The Companies (Auditor's Report) Order, commonly known as CARO, requires auditors to make reporting on specified matters for companies to which the Order applies, subject to the exemptions and exclusions prescribed under the applicable framework.

Internal Audit

Internal audit focuses more on internal controls, processes, risk management and operational effectiveness. It is mandatory for prescribed classes of companies and may also be voluntarily adopted by other businesses.

9. Statutory Audit vs Tax Audit

Statutory audit and tax audit are often confused because both involve examination of financial information. However, they are conducted for different legal purposes.

A company can therefore be subject to statutory audit even if the specific conditions for a separate tax audit are not met.

10. CARO Applicability for Companies

CARO stands for the Companies (Auditor's Report) Order. It prescribes additional reporting requirements for auditors in relation to specified matters.

CARO does not automatically apply in exactly the same way to every company. Certain categories and companies meeting specified conditions may fall outside its scope.

Consequently, businesses should not simply assume that their auditor's report will contain the same CARO reporting for every company.

11. When Is Internal Audit Mandatory?

Internal audit is mandatory for prescribed classes of companies under the Companies Act and the applicable rules.

The applicability depends on factors such as the company's category and prescribed financial or operational criteria.

Even where internal audit is not legally mandatory, a growing company may benefit significantly from periodic internal reviews of:

• cash and bank controls;
• purchase and sales processes;
• inventory management;
• GST compliance;
• vendor and customer balances;
• expense approvals;
• payroll controls;
• fraud risks; and
• financial reporting controls.

12. Are There Any Exemptions From Company Audit?

The most important point is that companies should not treat every compliance relaxation as an exemption from statutory audit.

Certain provisions may provide exemptions from specific reporting orders, internal audit requirements, filing requirements or other compliance provisions depending on the company's circumstances.

This is different from eliminating the statutory audit requirement itself.

Examples of Areas That May Have Separate Relaxations

• CARO reporting may not apply to certain excluded classes of companies.
• Internal audit requirements apply only to prescribed classes.
• Smaller companies may receive certain compliance relaxations.
• Different financial reporting formats may apply to specified company categories.

13. Documents Required for Company Audit

Preparing complete and organised documents can make the audit process faster and reduce unnecessary queries from the auditor.

The exact documents required can vary depending on the company's business model, transactions, industry and auditor's audit plan.

14. Company Audit Process in India

Although audit procedures differ between businesses, the overall process generally follows a structured sequence.

Step 1: Prepare the Books of Accounts

The company should ensure that accounting records are updated and reconciled before the audit begins.

Step 2: Share Financial Records

The company provides the auditor with ledgers, bank records, invoices, statutory records, schedules and other supporting information.

Step 3: Auditor Performs Verification

The auditor examines selected transactions, balances, controls, supporting documents and financial reporting matters.

Step 4: Resolve Audit Queries

The company responds to audit queries and provides explanations or additional evidence where required.

Step 5: Finalise Financial Statements

Necessary adjustments and disclosures are considered before the financial statements are finalised.

Step 6: Auditor's Report

The statutory auditor issues the audit report based on the audit performed and evidence obtained.

Step 7: Complete Corporate Compliance

After the financial statements and audit report are finalised, the company should complete the applicable corporate filings and annual compliance within the prescribed timelines.

15. What Happens If a Company Does Not Complete Its Audit?

Failure to comply with statutory audit obligations can expose a company and responsible persons to legal and regulatory consequences.

Depending on the specific default, consequences may include:

• penalties under the Companies Act;
• issues with annual financial statement filings;
• regulatory notices or compliance action;
• difficulty completing related corporate compliances;
• higher professional and remedial costs; and
• possible consequences for officers responsible for the default.

Section 147 of the Companies Act contains provisions relating to penalties for contravention of audit-related provisions.

18. Common Company Audit Mistakes to Avoid

Many audit problems can be prevented by maintaining proper records throughout the financial year.

1. Waiting Until the Last Minute

Delayed accounting creates unnecessary pressure and can result in missing documents or unresolved differences.

2. Ignoring Bank Reconciliation

Old unreconciled entries can create questions during the audit and may indicate accounting errors.

3. Not Reconciling GST Data

Differences between books, GST returns and supporting documents should be identified and reviewed.

4. Poor Documentation

Unsupported expenses, missing invoices and incomplete agreements can make the audit process harder.

5. Incorrect Treatment of Related-Party Transactions

Related-party transactions may require specific accounting, disclosure and compliance consideration.

6. Ignoring Statutory Dues

Outstanding statutory dues should be properly tracked and reconciled.

7. Treating Audit as Only a Form-Filing Exercise

An audit is a financial and compliance review. Simply completing a filing without maintaining reliable underlying records can create serious problems later.

21. Final Takeaway

So, is audit mandatory for all companies in India? Generally, yes. Companies incorporated under the Companies Act are generally required to undergo statutory audit and comply with the applicable auditor appointment, financial statement and reporting requirements.

However, statutory audit should be clearly distinguished from tax audit, CARO reporting and internal audit. Each requirement has its own legal basis and applicability conditions.

Private companies, small companies, OPCs and dormant companies should not assume that their size or inactive status automatically eliminates statutory audit obligations.

Maintaining accurate books, reconciling GST and tax records, organising supporting documents and starting the audit process early can make annual compliance significantly easier.
