Expert verified Internal audit documentation requirements in India are essential to understand for ensuring regulatory compliance, risk management, and transparency.
Explore with us these requirements, the laws behind it, the list and a quick internal audit documentation checklist to help you get ready.
Legal Framework for Internal Audit Documentation in India
The legal framework for internal audit documentation is based primarily on the following laws and mandates:
Companies Act, 2013:
Mandates internal audits for certain classes of companies.
Under Section 138, it clearly states that companies meeting certain criteria must appoint an internal auditor and maintain audit records to prove they’re doing their job.
These records must be made available to external auditors and regulatory bodies on request.
Securities and Exchange Board of India (SEBI) Regulations:
Impose additional documentation requirements for listed companies.
The SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, mandate that listed companies maintain comprehensive internal audit documentation to support their compliance with corporate governance norms.
Mandates:
- Proper audit trails
- Internal controls over financial reporting
- Evidence of compliance
Reserve Bank of India (RBI) Circulars (for Banks & NBFCs)
Govern internal audit documentation for banks and NBFCs (Non-Banking Financial Companies.
These require strong internal audit functions and require:
- Risk-based audit documentation
- Independent audit trails
- Records of internal control tests
RBI inspections often request these documents during on-site reviews.
Institute of Chartered Accountants of India (ICAI):
Issues the “Standards on Internal Audit” (SIAs), which set the professional and documentation standards for internal auditors across India.
Their standard SA 230: Audit Documentation outlines:
- What documents must be kept
- How to record audit evidence
- When and how to finalize documentation
- Retention period (typically 7 years)
Institute of Internal Auditors (IIA) Standards
Provide international best practices for audit documentation.
These specify requirements for documenting audit planning, fieldwork, and reporting phases.
Controller and Auditor General (CAG) and ICAI:
Both have issued manuals and guidelines for internal audit in government and public sector entities, emphasizing rigorous, documented, and reviewable audit trails.
Mandatory Documents Required in Internal Audits
Internal audits in India must follow strict documentation norms as mandated by the laws and governing authorities discussed above.
The mandatory documents are organized into three main categories based on the internal audit process.
I. Audit Planning
These documents lay the foundation of the audit. They help establish the scope and direction of the internal audit assignment:
📋 Annual Internal Audit Plan:
Outlines the planned audits for the year, including the business units, processes, and locations to be covered.
It must be approved by the Audit Committee and should align with the needs of the organization, regulatory expectations (e.g., Companies Act, 2013, SEBI), and assessed risks.
📋 Risk Assessment & Audit Universe
Identifies and ranks auditable areas based on risk factors such as materiality, complexity, and strategic importance.
It includes a risk assessment matrix with scoring methodologies, helping prioritize audits and ensure adequate risk coverage.
📋 Audit Committee Charter & Terms of Reference
Define the scope, authority, and independence of the internal audit function.
They also clarify the Audit Committee’s responsibilities in approving audit plans, reviewing results, and ensuring follow-up actions.
📋 Engagement Letter / Internal Audit Charter

📋 Planning Memos / Checklists
Supporting documents such as notes, templates, and questionnaires used during the planning phase of audits.
They provide evidence of thoughtful planning and alignment with audit objectives.
II. Fieldwork Documentation
These documents are related to executing the internal audit and gathering evidence. The mandatory documents usually include:
📜Working Papers and Audit Evidence

For regulated sectors like banking, this includes testing of KYC norms, AML practices, and other regulatory standards.

They provide a structured approach for capturing control design, execution, and risk exposures.

Evaluations of account balances, trends, and variances used to identify unusual patterns or potential risk areas.
They form a key part of audit fieldwork and help corroborate or challenge other findings.
📜Meeting Notes and Interview Records

How to Structure Internal Audit Documentation?
A standardized internal audit documentation system ensures that auditors, management, and regulators can easily locate information without ambiguity or wasted time.
Here are some pointers to help you stay on top of the documentation:
1. Establish a Clear Folder Hierarchy
Organize files by Year → Department → Audit Type for logical navigation.
Add timestamps (e.g.,Jan2025) to filenames for chronological sorting.
2. Organize by Audit Phases
Divide folders into three primary phases:
| Folder Name | Includes |
| 01_Planning | Audit plan, risk assessment, checklists |
| 02_Fieldwork | Working papers, control tests, observations |
| 03_Reporting | Draft/final reports, CAPA, closure documentation |
This aligns with expectations from regulators and reviewers.
3. Use Consistent File Naming Conventions
Apply a standardized naming format that includes Audit Area, Document Type, Date. Auditor and extension (pdf, png, etc.
Avoid generic or unclear names like Document(1).pdf or FINAL-final-v2.docx.
Examples:
- Finance_RiskAssessment_Jan2025_RMehta.xlsx
- HR_WorkingPaper_LeavePolicy_Auditor1.docx
4. Maintain a Document Index or Control Sheet
Create a centralized index of the internal audits documents. This speeds up reviews and improves audit traceability.
It should capture:
- Document Name
- Version Number
- Author
- Status (Draft/Final)
- Last Updated
- File Path or Link
5. Set Appropriate Access Permissions
Use secure platforms to control access:
- Google Drive
- SharePoint
- Zoho WorkDrive
- OneDrive
- AuditBoard
For security restrict editing rights, maintain view-only backups and store read-only versions for final reports
6. Consolidate Reviews and Approvals
Keep all review history within documents. Avoid relying on email chains. This will result in a clear, audit-ready approval trail.
Options:
- Add comments directly within the document
- Use digital signatures (DSC or Aadhaar eSign)
- Include a sign-off sheet in each audit phase folder
7. Archive Older Files Securely
ICAI recommends maintaining records for 7 years.
Organize archives year wise and use locked cloud folders or zip files for read-only access.
