What is a Internal Audit Engagement Letter?

The Internal Audit Engagement Letter is a crucial document used in Indonesian business practice to formally initiate and define the parameters of an internal audit engagement. It serves as the primary reference document that outlines the scope, objectives, methodology, and expectations of the internal audit process. This document is essential when commencing any internal audit activity and must comply with Indonesian regulations, particularly OJK Regulation No. 56/POJK.04/2015 and relevant Bank Indonesia regulations for financial institutions. The letter typically includes details about the audit timeline, resource requirements, reporting protocols, and specific areas under review. It's designed to ensure clear communication between the internal audit function and the audited department while maintaining alignment with both local regulatory requirements and international internal audit standards. The document becomes particularly important in regulated industries and public companies where formal documentation of audit processes is mandatory.

About the Internal Audit Engagement Letter

When conducting internal audits in Indonesia, you need a formal Internal Audit Engagement Letter to establish clear parameters and ensure regulatory compliance. This document serves as your primary reference throughout the audit process, defining objectives, scope, methodology, and expectations between the internal audit department and the unit being audited.

When do you need this document?

You require an Internal Audit Engagement Letter before commencing any internal audit activity in your Indonesian company. This includes routine operational audits, compliance reviews, risk assessments, financial audits, and special investigations. The letter becomes mandatory when your company falls under OJK supervision, operates in regulated industries like banking or insurance, or when conducting audits of critical business processes. You also need this document when establishing new audit engagements with different departments, conducting follow-up audits, or when audit scope significantly changes from previous engagements.

Key legal considerations

Your engagement letter must clearly define the audit's objective and scope to prevent disputes and ensure thoroughness. Include specific methodologies you'll employ, referencing both Indonesian standards and International Internal Auditing Standards where applicable. Address confidentiality requirements and data protection obligations, particularly for sensitive financial or personal information covered under Indonesia's Electronic Information and Transactions Law. Establish clear reporting lines and communication protocols, ensuring independence from the audited unit while maintaining accountability to senior management and audit committees. Define timeline expectations, resource requirements, and cooperation levels needed from the audited department. Include provisions for accessing necessary documents, systems, and personnel, while respecting operational continuity.

Legal requirements in Indonesia

Under OJK Regulation No. 56/POJK.04/2015, your Internal Audit Engagement Letter must align with your company's Internal Audit Charter and demonstrate compliance with regulatory expectations for audit planning and execution. Company Law No. 40 of 2007 requires that internal audit activities support proper corporate governance and internal control systems. For banking institutions, ensure compliance with Bank Indonesia Regulation No. 1/6/PBI/1999 regarding internal audit standards. Your letter must be signed by appropriate authorities, typically including the Head of Internal Audit Department and the relevant Department Head or Director. Maintain proper documentation as required by Indonesian corporate law, ensuring the letter is dated, numbered, and filed according to your company's document retention policies. The engagement letter should reference applicable Indonesian accounting standards and regulatory frameworks specific to your industry sector.
