What is the Difference Between Internal Audit and Statutory Audit?

For companies across the world, the audits play an indispensable role. They help companies to maintain their financial records properly, meet regulatory/legal requirements and gain confidence of stakeholders. There are different types of audits and each one of them serves a different purpose. Among them, internal audit and statutory audit are two of most prominent types. An internal audit is conducted with purpose of improving controls as well as efficiency of business. It is conducted by internal audit staff, an outsourced professional firm or a co-sourced team having both employees and external specialists. 

A statutory audit, on other hand, is conducted with purpose of verifying financial accuracy. It is conducted by independent external auditors, which means that the company’s employees do not conduct it. Now, you know the basic difference between internal audit and statutory audit. But there are many more differences between them that you should know, especially if you are planning to register a company in India in the near future.

Internal Audit vs Statutory Audit: Key Differences (Table)

In the table below, we have given the main differences between internal audit and statutory audit. Once you go through all the differences, you will understand how exactly these two types of audit differ from each other:

Base Internal Audit Statutory Audit
Definition Internal audit is an audit conducted by a company to identify problems and fix them, improve daily business operations and strengthen internal controls. Statutory audit is an audit conducted by an independent external auditor to examine the financial records of a company and confirm whether the financial statements give a true and fair view of financial position of company.
Who Conducts It? Internal audit team, external professional firm or a co-sourced team comprising company employees and external specialists.  Independent external auditor who is a practicising CA or a firm of CAs eligible to conduct statutory audits.
Auditor’s Qualification Individuals conducting the internal audits may or may not be chartered accountant (CA).

Non-chartered accountants, like cost accountants or other professionals, may also conduct these audits if approved by the board of directors of the company.
Only practising CAs and CA firms can conduct statutory audits.
Requirement under Law An internal audit is usually optional for most companies. However, for certain companies, it is mandatory. 

This includes every listed company on stock exchanges as well as unlisted public companies having paid-up share capital of Rs. 50 crore or more, turnover of Rs. 200 crore or more, outstanding loans or borrowings from banks or public financial institutions exceeding Rs. 100 crore, or outstanding deposits of Rs. 25 crore or more.

For private companies, internal audit becomes a mandatory compliance requirement if they have turnover of Rs. 200 crore or more or outstanding loans or borrowings from banks or public financial institutions exceeding Rs. 100 crore.
For each and every company incorporated under the Companies Act, conducting a statutory audit is a mandatory compliance requirement. 

This holds true regardless of whether the company is private or public, listed or unlisted, small or large, profit-making or loss-making or has zero revenue.
Frequency of Audit Ongoing, monthly, quarterly or half-yearly. Once in every financial year.

What is Internal Audit?

Internal audit is an audit conducted by a company for its management and board of directors. This audit allows the company to identify problems and fix them, improve daily operations, make business more efficient and strengthen internal controls. The aim of the internal audit is to find out problems that may affect company’s business and come up with ways to improve them. An internal audit may be conducted by the company’s own internal audit team without the engagement of an external party. It may also be conducted by an outside professional firm or by a team of company employees and external professionals working together.

Internal audit helps management and the board of directors run the organization in a much better way. It also checks whether employees are sticking to the company policies, industry rules and prevailing laws. It also checks systems and controls so as to protect company assets, keep data and records accurate and reduce the risk of errors and fraud. In this way, internal audit helps a company identify all its weaknesses, improve its processes, reduce risks and make business operations much more efficient as well as effective.

What is Statutory Audit?

Statutory audit is an audit conducted by an independent external auditor appointed by the shareholders or members of a company. Each and every company registered under the Companies Act, 2013, is required to undergo this type of audit once in a financial year. This is regardless of whether the company is a private limited or public company, small or big, making profit, loss or having zero revenue. Simply put, every company covered under the Act is required to undergo a statutory audit. 

The statutory audit is conducted to check financial records of a company and confirm whether the financial statements give real picture of financial position of company. One more thing is that the independent external auditor has to be an independent Chartered Accountant (CA) in practice or a firm of CAs eligible to conduct the audit under the Act. The resulting audit report based on the statutory audit must be presented to the shareholders at Annual General Meeting.
