Introduction

India's evolving regulatory landscape demands that businesses of all sizes maintain robust internal controls and governance frameworks. Whether you operate a manufacturing unit, a financial services firm, an IT company, or a trading enterprise, internal audit is no longer optional. It is a strategic tool that helps management identify risks, strengthen controls, and improve operational efficiency.

Internal audit in India is governed by standards issued by the Institute of Chartered Accountants of India (ICAI) and mandated under various laws including the Companies Act, 2013. At Patron Accounting, we deliver tailored internal audit services that address your specific industry risks and compliance requirements, helping you build a stronger and more accountable organisation.

What is Internal Audit?

Internal audit is an independent, objective assurance and consulting activity designed to add value and improve an organisation's operations. It helps an organisation accomplish its objectives by bringing a systematic, disciplined approach to evaluating and improving the effectiveness of risk management, control, and governance processes.

Unlike statutory audit, which is mandated by law for verifying financial statements, internal audit focuses on operational efficiency, risk identification, and internal control adequacy. The Ministry of Corporate Affairs (MCA) under the Companies Act, 2013 has made internal audit mandatory for certain classes of companies, signalling its growing importance in Indian corporate governance.

Requirements

Mandatory Applicability Under Companies Act, 2013

Section 138 of the Companies Act, 2013 read with Rule 13 of the Companies (Accounts) Rules, 2014 makes internal audit mandatory for the following classes of companies:

Please Note: Companies meeting any of these thresholds must appoint a qualified internal auditor. Non-compliance attracts penalties under the Companies Act. For banking and financial sector entities, Reserve Bank of India (RBI) guidelines further mandate concurrent and revenue audits in addition to risk-based internal audit.

Our Process

Internal Audit Process in India

Our structured internal audit methodology ensures thorough coverage and actionable outcomes across every engagement.

STEP 1

Engagement Planning and Risk Assessment

We begin by understanding your business operations, industry risks, and regulatory environment. Our team conducts a preliminary risk assessment to identify high-risk areas and prioritises audit focus accordingly. An audit plan covering scope, objectives, timelines, and team composition is shared with management for agreement.

STEP 2

Fieldwork and Evidence Gathering

Our auditors perform on-site and remote testing of transactions, processes, and controls. We use a combination of inquiry, observation, inspection of documents, and analytical procedures. Sample sizes are determined based on risk levels and transaction volumes.

STEP 3

Control Evaluation and Gap Analysis

Each process is mapped against control objectives to identify design gaps and operating effectiveness failures. We evaluate whether existing controls are adequate to mitigate identified risks and document all findings with supporting evidence.

STEP 4

Draft Report and Management Discussion

A draft audit report is prepared listing observations, root causes, risk ratings, and recommendations. We discuss findings with department heads and senior management to obtain their responses and action plans before finalising the report.

STEP 5

Final Audit Report Issuance

The final internal audit report is submitted to the Audit Committee or Board of Directors as applicable. The report includes an executive summary, detailed findings, management responses, and a prioritised implementation roadmap.

Documents Required for Internal Audit Engagement

To initiate an internal audit engagement efficiently, clients are typically requested to provide:

Required Documents

Last 2 to 3 years' audited financial statements and trial balance
Organisation chart and delegation of authority matrix
Standard operating procedures (SOPs) and internal policy documents
Chart of accounts and ERP system access for sample testing
Previous internal and statutory audit reports with management responses
Contracts with key vendors, customers, and service providers
Bank statements, loan sanction letters, and security documents
Fixed asset register and inventory records
HR policies, payroll data, and leave records
GST returns, TDS statements, and other tax compliance records

Who Needs Internal Audit Services?

Internal audit services in India are beneficial and in certain cases mandatory for:

Listed companies and public interest entities regulated by SEBI
Private Limited Companies with turnover exceeding Rs. 50 crore or borrowings exceeding Rs. 25 crore
Banks, NBFCs, and financial institutions under RBI oversight
Government enterprises and PSUs requiring compliance audits
NGOs and societies handling large grant-funded programmes
Startups preparing for due diligence before funding rounds
Businesses with multiple locations, branches, or franchisee operations
Companies with complex supply chains or significant inventory holdings
Organisations implementing new ERP systems or undergoing major process changes

Time Required to Complete Internal Audit

Audit timelines depend on the scope agreed, number of locations, and availability of client teams:

Planning and risk assessment: 2 to 5 working days
Fieldwork and testing: 5 to 15 working days depending on scope
Report drafting and management discussion: 3 to 5 working days
Final report issuance: 2 to 3 working days after management responses
Total typical engagement duration: 2 to 4 weeks

Organisations that maintain organised records, provide timely access to data, and cooperate with auditors can expect faster turnaround. Delays typically arise from incomplete records or unavailability of key personnel.

Benefits of Internal Audit Services

Strengthened Risk Management

Internal audit provides management with an independent view of risks facing the business. By identifying vulnerabilities before they escalate, organisations can take proactive corrective action and avoid costly disruptions.

Improved Operational Efficiency

Process reviews conducted during internal audit frequently uncover redundant steps, manual workarounds, and inefficiencies that slow down operations. Implementing audit recommendations drives measurable productivity improvements.

Regulatory Compliance Assurance

India's compliance environment spans dozens of laws including the Companies Act, GST, TDS, PF, ESI, and sector-specific regulations from bodies like SEBI and RBI. Internal audit helps ensure you remain on the right side of these obligations and avoids penalties.

Fraud Prevention and Detection

Regular internal audits create a deterrence effect against fraud and misappropriation. Auditors can identify suspicious patterns in transactions and recommend controls that reduce opportunities for financial misconduct.

Board and Stakeholder Confidence

A well-functioning internal audit function signals strong governance to investors, lenders, regulators, and customers. Companies with credible internal audit programmes attract better financing terms and command greater stakeholder trust.

Comparison: Internal Audit vs Statutory Audit vs Concurrent Audit

Parameter	Internal Audit	Statutory Audit	Concurrent Audit
Objective	Risk and control review	Financial statement opinion	Real-time transaction review
Frequency	Quarterly or ongoing	Annual	Monthly or continuous
Appointed By	Management/Board	Shareholders	Management/Regulator
Regulatory Mandate	Companies Act (certain cos.)	All companies	Banks (RBI mandate)
Scope	Broad (operations, finance, IT)	Financial statements only	Specific transactions
Output	Management report	Audit opinion/certificate	Exception reports

                Please Note:  Internal Audit improves internal controls, Statutory Audit gives a legal opinion on accounts, and Concurrent Audit checks transactions on a real-time basis.
                        

Post-Audit Compliance and Best Practices

Completing an internal audit engagement is the beginning, not the end, of the improvement cycle. To maximise value from your internal audit:

Ensure Audit Committee review of all internal audit reports as required under the Companies Act and Listing Obligations
Assign clear ownership for each audit observation with defined timelines for resolution
Track implementation of corrective actions through a formal audit action tracker
Report internal audit status to the Board of Directors at least quarterly
Update the risk register based on audit findings to keep it current
Review income tax implications of any adjustments arising from audit findings in consultation with your tax advisor and refer to guidance from the Income Tax Department where applicable
Schedule follow-up audits within 90 days to verify closure of high-risk observations

                   Please Note:  With Patron Accounting, clients receive more than just compliance; they gain actionable insights to optimize inventory management, enhance profitability, and strengthen corporate governance.

Frequently Asked Questions

Have a look at the answers to the most asked questions.

No. Internal audit is mandatory under Section 138 of the Companies Act, 2013 only for certain classes of companies based on turnover, borrowings, or paid-up capital thresholds. However, many companies voluntarily appoint internal auditors as a good governance practice regardless of mandatory applicability.

A Chartered Accountant, Cost Accountant, or any other professional as decided by the Board of Directors can be appointed as an internal auditor. The person may be internal (employee) or external (professional firm). Listed companies generally prefer external independent internal auditors.

Statutory audit is performed to verify the accuracy of financial statements and is mandated by the Companies Act for all registered companies. Internal audit focuses on evaluating the adequacy of internal controls, risk management processes, and operational efficiency. The internal auditor reports to management while the statutory auditor reports to shareholders.

Most organisations conduct internal audit on a quarterly basis covering different process areas each quarter. High-risk areas like cash management, inventory, and payroll are typically covered more frequently. The frequency should be documented in the internal audit plan approved by the Audit Committee.

A risk-based approach prioritises audit resources on areas with the highest inherent risk to the organisation. Instead of auditing every process equally, the auditor identifies high, medium, and low-risk areas through a risk assessment and allocates more attention to high-risk processes. This maximises the value delivered from limited audit time.

Yes. Internal audit can review GST return accuracy, input tax credit reconciliation, classification of supplies, and timely payment of liabilities. Identifying GST errors before a department inspection significantly reduces the risk of penalties and interest charges.

An Audit Committee is a sub-committee of the Board of Directors responsible for overseeing financial reporting, internal controls, and the audit function. It is mandatory for listed companies and certain public companies under the Companies Act, 2013. The internal auditor is required to report findings to the Audit Committee.

Failure to comply with Section 138 attracts penalties on the company and officers in default under Section 450 of the Companies Act. Additionally, non-compliance can trigger adverse observations in statutory audit reports and regulatory scrutiny during inspections.

Yes. Patron Accounting provides internal audit services across major cities and industrial hubs in India including Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Pune, Kolkata, and Agra. Remote audit engagements are also available for geographically dispersed organisations.

Internal audit reports are internal management documents and are generally not shared with regulators unless specifically required by law or court order. However, regulators like RBI and SEBI may review internal audit processes and reports during inspections of regulated entities to assess governance standards.
