The IAASB invites stakeholders worldwide to participate in its public consultation survey as part of its post-implementation review of International Standard on Auditing (ISA) 540 (Revised), Auditing Accounting Estimates and Related Disclosures.

ISA 540 (Revised) established more robust requirements and appropriately detailed guidance to foster audit quality by driving auditors to perform appropriate procedures in relation to accounting estimates and related disclosures. The standard was effective for audits of financial statements for periods beginning on or after December 15, 2019.

This survey seeks input from a broad range of stakeholders and includes questions tailored to differing perspectives and experiences of various stakeholder groups.

The survey focuses on three principal areas:

  • Overall views on ISA 540 (Revised), including related to non-authoritative guidance and tools that were issued to support implementation of the standard;
  • Perceived benefits resulting from implementation of the revised standard; and
  • Potential issues, challenges, or impacts experienced or observed relating to ISA 540 (Revised).

Stakeholders may respond to all questions or only those most relevant to their perspectives. All responses will form part of the public record.

The survey is open until June 15, 2026.
