An engagement letter should not be used as a substitute for the statutory auditor appointment.

What Is an Auditor Engagement Letter?

An auditor engagement letter records the terms under which the auditor will perform the audit.

Depending on the engagement, it can address:

  • Objective and scope
  • Applicable financial reporting framework
  • Auditor responsibilities
  • Management responsibilities
  • Access to records
  • Representations and information
  • Communication
  • Reporting
  • Remuneration
  • Expenses
  • Confidentiality
  • Other agreed terms

The final letter should be aligned with applicable law, professional standards and the actual engagement.

Engagement Letter vs Auditor Appointment

These are separate concepts.

Statutory appointment

The company appoints the auditor through the applicable Companies Act process.

Engagement letter

The auditor and company document the terms under which the audit engagement will be conducted.

An engagement letter cannot independently appoint an auditor where the Companies Act requires Board / member / CAG or another statutory process.

Auditor Appointment and Remuneration

The engagement documentation should distinguish:

  • Statutory auditor appointment
  • Auditor remuneration
  • Engagement terms
  • Reimbursement of expenses
  • Additional professional services, if any

The remuneration should be approved through the applicable corporate process and documented appropriately. The engagement letter itself does not determine or legally fix remuneration in every company.

What Should an Engagement Letter Contain?

1. Parties

Identify:

  • Company/legal entity
  • Auditor/audit firm
  • Registered details
  • Relevant contact persons

2. Appointment reference

State:

  • Appointment authority
  • Relevant resolution/date
  • Financial year/period
  • Applicable statutory framework

The letter should reflect the actual appointment rather than create a fictional appointment.

3. Objective

Explain that the engagement is to perform the agreed audit in accordance with applicable auditing standards and law.

4. Scope

Describe:

  • Financial statements covered
  • Reporting period
  • Applicable accounting framework
  • Statutory audit requirements
  • Additional agreed procedures, if any

Avoid calling a limited review or agreed-upon procedure a statutory audit.

5. Auditor responsibilities

Depending on the engagement, address:

  • Planning and performing the audit
  • Obtaining reasonable assurance
  • Assessing risks
  • Evaluating relevant evidence
  • Reporting in accordance with applicable standards

The letter should not promise a particular audit opinion.

6. Management responsibilities

Management generally remains responsible for:

  • Preparing financial statements
  • Maintaining appropriate books and records
  • Internal controls relevant to financial reporting
  • Providing information and explanations
  • Making accounting estimates and judgments
  • Providing access to records and personnel
  • Providing management representations where required

The engagement letter should clearly allocate these responsibilities.

7. Access to information

Specify that management will provide timely access to:

  • Books
  • Ledgers
  • Vouchers
  • Bank records
  • Contracts
  • Statutory records
  • Supporting documents
  • Relevant personnel
  • Other information required for the audit

The exact list should reflect the engagement.

Audit Standards

A statutory audit should be conducted in accordance with the auditing standards applicable to the engagement and relevant law.

The engagement letter should not list standards that do not apply to the entity or period.

Where professional standards change, the template should be updated.

Financial Reporting Framework

The letter should identify the relevant financial reporting framework, where appropriate, such as:

  • Companies Act requirements
  • Accounting Standards
  • Ind AS
  • Other applicable statutory framework

The correct framework depends on the company and applicable rules.

Internal Control Responsibility

Management remains responsible for establishing and maintaining appropriate internal controls.

The auditor evaluates controls as relevant to the audit and applicable auditing standards.

The engagement letter should not suggest that the auditor assumes management's control responsibilities.

Fraud and Error

The engagement terms should explain the respective responsibilities for:

  • Fraud
  • Error
  • Risk assessment
  • Internal controls
  • Reporting of identified matters

An audit provides reasonable assurance, not a guarantee that every fraud or error will be detected.

Going Concern

Where applicable, the audit considers management's assessment of going concern and related evidence under the relevant auditing standards.

The engagement letter should not promise a particular going-concern conclusion.

Statutory Registers and Records

Where relevant to the audit, the company should provide access to:

  • Minutes
  • Statutory registers
  • Share capital records
  • Related-party records
  • Loans/guarantees
  • Charges
  • Material contracts
  • Tax/GST records
  • Other statutory information

The audit scope should be clearly distinguished from a separate corporate-secretarial compliance engagement.

Audit Committee Communication

Where an Audit Committee applies, the engagement can specify communication arrangements for:

  • Audit planning
  • Significant findings
  • Internal control matters
  • Key accounting judgments
  • Going concern
  • Related-party matters
  • Auditor independence
  • Other required communications

The exact reporting requirements depend on the company and applicable standards.

Auditor Independence

The engagement should not override statutory and professional independence requirements.

The auditor should assess:

  • Financial interests
  • Business relationships
  • Loans/guarantees
  • Non-audit services
  • Relative/family interests
  • Partner relationships
  • Other independence matters

See Auditor Eligibility & Disqualification.

Non-Audit Services

Section 144 restricts specified services by statutory auditors to companies and specified related entities.

An engagement letter should not bundle prohibited services into a statutory audit engagement.

Where additional services are proposed, assess them separately before acceptance.

Confidentiality and Data Access

The engagement can include appropriate provisions relating to:

  • Confidentiality
  • Data handling
  • Secure document transfer
  • Access credentials
  • Retention
  • Return/destruction of documents

These provisions should be consistent with applicable law and professional obligations.

Use of Technology

If the engagement uses:

  • Accounting software
  • Cloud document systems
  • Remote access
  • Data extraction tools
  • Analytical tools

The engagement should describe the process only to the extent actually used.

Audit Evidence and Management Representations

The company may be required to provide:

  • Management representations
  • Confirmations
  • Supporting schedules
  • Reconciliations
  • Explanations
  • Other evidence

The engagement letter can establish expectations for timely cooperation.

Reporting

The engagement should identify the expected statutory reporting deliverables where applicable.

The engagement letter cannot guarantee:

  • Clean/unmodified opinion
  • No qualifications
  • No observations
  • No internal-control findings
  • No tax/GST consequences

The audit conclusion depends on the evidence and applicable standards.

Changes to Engagement Scope

If the company requests additional work, document:

  • New scope
  • Additional procedures
  • Additional fee
  • Revised timeline
  • Reporting impact

Do not silently expand a statutory audit engagement into advisory, bookkeeping or other services.

Additional Services

Potential additional services may include separate engagements such as:

  • Tax audit
  • GST reconciliation
  • Internal audit
  • Accounting support
  • Certification
  • Due diligence
  • Compliance review

Each should be checked for independence and statutory restrictions before acceptance.

Engagement Letter for Reappointment

For reappointment:

  • Confirm continuing eligibility
  • Review independence
  • Check rotation
  • Confirm scope
  • Update remuneration
  • Refresh management responsibilities
  • Update reporting and communication arrangements

Do not simply reuse the previous year's letter where circumstances have changed.

Engagement Letter After Auditor Resignation / Replacement

A replacement auditor should execute a fresh engagement arrangement appropriate to the new appointment.

The company should provide:

  • Appointment documents
  • Previous auditor information where relevant
  • Opening balances/information
  • Books and records
  • Statutory records
  • Other required audit evidence

See Casual Vacancy of Auditor.

Engagement Letter and Audit Fee

CorporateWalla's documentation assistance fee, if any, is separate from the auditor's audit remuneration.

The engagement letter can document the agreed professional fee and billing terms, subject to the applicable corporate approval and professional requirements.

Common Mistakes

Treating an engagement letter as the appointment

It documents the engagement; it does not replace the statutory appointment process.

Promising a clean audit report

An audit opinion depends on evidence and applicable standards.

Making management responsible for the auditor's work

Management and auditor responsibilities should be clearly separated.

Making the auditor responsible for management controls

The auditor does not assume management's responsibility for internal controls.

Bundling prohibited non-audit services

Section 144 restrictions must be checked before accepting additional services.

Reusing an outdated letter

Standards, law, company circumstances and scope can change.

Leaving scope vague

The letter should identify the financial statements and period covered.

Ignoring remuneration approval

Auditor remuneration should follow the applicable corporate process.

Treating all software support as audit scope

Bookkeeping, implementation and system work can be separate engagements.

Engagement-letter drafting and review is quoted on scope, because the work depends on whether the engagement is new or continuing, the company type, listed or government status, audit complexity, reporting frameworks, additional clauses, group-company arrangements, regulatory requirements and the review or redrafting required. CorporateWalla's documentation fee is separate from the auditor's audit remuneration and excludes GST.
