Audit assertions are statements by management, either express or implied, regarding the accuracy of each component in the financial statements, which form the basis for auditor<\/a><\/strong> to design test procedures. Every figure presented by management contains a claim: that transactions occurred, balances exist, amounts are correct, and disclosures are complete. The auditor's job is to test whether these claims are substantiated.<\/p>\n\n\n\n

Based on Auditing Standard (SA) 315<\/a><\/strong> Published by the Indonesian Institute of Certified Public Accountants (IAPI), in line with ISA 315 (Revised), audit assertions are grouped into three main categories, encompassing a total of 13 assertions. This article discusses their definition, latest classification, function, examples, and application in the modern audit process.<\/p>\n\n\n\n

\n

Important notes:<\/strong> Many older references still refer to the \"five types of assertions\" (existence, completeness, rights and obligations, valuation, and presentation). This framework stems from previous standards. Current auditing standards group them into three categories based on the object being audited. This article uses the current classification.<\/p>\n<\/blockquote>\n\n\n\n

What is an Audit Assertion?<\/h2>\n\n\n\n

Audit assertions (audit assertions<\/em> or management assertions<\/em>) is management's representation of transactions, account balances, and disclosures in the financial statements. When management presents financial report<\/a><\/strong>, they implicitly state that each element meets certain criteria, for example that the recorded inventory actually exists and is owned by the entity.<\/p>\n\n\n\n

Assertions serve as the reference point for testing. Auditors do not randomly test financial statements, but rather map each account to the relevant assertion and then design audit procedures to obtain evidence for each assertion. This is why assertions are the foundation for risk assessment and audit program development.<\/p>\n\n\n\n

Assertions can be explicit<\/strong> (stated in writing in the management representation letter) or implicit<\/strong> (attached to the presentation of the numbers themselves).<\/p>\n\n\n\n

According to SA 315, assertions are classified based on the objects being audited: transactions during the current period, account balances at the end of the period, and presentation and disclosure.<\/p>\n\n\n\n
