What is International Standard on Auditing (ISA)?
The International Standard on Auditing (ISA) refers to statements that outline the basic principles and essential procedures for auditing issued by the International Auditing and Assurance Standards Board (IAASB). These standards aim to enhance the quality and consistency of audits across the globe.
ISAs provide audit professionals with a framework that promotes transparency and accountability in financial reporting. They specify criteria for ethical conduct, auditor qualifications, and the scope of the audit work. In the UK and Ireland, auditors must comply with ISAs (UK and Ireland) for any statutory audit. Revised ISAs were issued in January 2015 and apply to audits for periods ending on or after December 15, 2016.

- ISA 700 (Revised): Forming an Opinion and Reporting on Financial Statements.
- ISA 240: The Auditor’s Responsibilities Relating to Fraud in an Audit of Financial Statements.
