Updated July 2026
At its June 2026 meeting, the IAASB unanimously approved the exposure drafts for:
- Proposed International Standard on Auditing (ISA) 330 (Revised);
- Proposed ISA 500 (Revised), Audit Evidence;
- Proposed ISA 520 (Revised), Analytical Procedures; and
- Related conforming and consequential amendments arising from the proposed revisions.
The revisions to the three standards address, in an integrated manner, foundational aspects of obtaining and evaluating audit evidence by designing and performing audit procedures to obtain sufficient and appropriate audit evidence. The key outcomes of the concurrent revisions aim to improve consistency in the auditor’s work effort supporting the delivery of high-quality audits by:
- Setting out a comprehensive framework for making judgments about audit evidence, including the alignment of concepts and principles among the standards to support coherent and consistent work effort;
- Enhancing the focus on professional skepticism when obtaining and evaluating audit evidence and in responding to risks of material misstatement;
- Facilitating the design of robust procedures capable of detecting material misstatements at the assertion level by clarifying the principles underpinning effective substantive procedures;
- Clarifying and strengthening the auditor’s work on internal controls by broadening the scope of tests of controls and supporting auditors in exercising appropriate judgment about whether and when testing controls is an appropriate response to assessed risks of material misstatement; and
- Recognizing the need for the standards to remain principle-based, flexible and fit-for-purpose in a technologically evolving environment by considering the broad impact of technology in formulating the proposals for the in-scope standard and clarifying how the principle-based requirements apply when using technological tools to obtain and evaluate audit evidence.
The Explanatory Memoranda accompanying the exposure drafts will be issued for public comment in early August 2026 for an approximate 130-day comment period.

Updated July 2026
In June 2026, the IAASB discussed all topics on inventory and external confirmations included in the approved project proposal to revise the following audit evidence standards in the ISA 500 Series:
- ISA 501, Audit Evidence —Specific Considerations for Selected Items —only relating to inventory; and
- ISA 505, External Confirmations.
The IAASB aims to modernize these standards to more appropriately reflect the business and audit environment. This includes addressing the implications of the use of technology by entities and auditors in a principles-based way so that the standards remain fit-for-purpose and addressing new or evolving risks and practical considerations, as well as reinforcing the exercise of professional skepticism.
In September 2026, the IAASB will discuss the first full drafts of Proposed ISA 501 (Revised) as it relates to inventory and Proposed ISA 505 (Revised), with an exposure draft targeted for approval in December 2026.
For further information, visit the ISA 500 Series project page.
Updated March 2026
At the December 2025 meeting, the IAASB approved the project proposal of the first revision of the International Standard on Auditing for Audits of Financial Statements of Less Complex Entities (the ISA for LCE), as a result of the following IAASB projects:
- ISA 240 (Revised), The Auditor’s Responsibilities Relating to Fraud in an Audit of Financial Statements;
- ISA 570 (Revised 2024), Going Concern;
- The narrow scope amendments to the ISAs as a result of the revisions to the definitions of listed entity and public interest entity in IESBA Code; and
- The narrow scope amendments to IAASB Standards arising from the IESBA’s using the work of an external expert project.
This maintenance project is being conducted in line with the IAASB Approach Statement, as discussed and cleared by the IAASB in December 2025.
Following the discussion of the first full draft of the proposed revised ISA for LCE at the March 2026 meeting, the Project Team will engage directly with relevant stakeholders to obtain insights on whether the proposed revisions are proportionate to the typical nature and circumstances of a less complex entity (LCE). In June 2026, the IAASB will review and discuss an updated draft of the revised standard for approval.

Updated July 2026
Following the launch in January 2025 of International Standard on Sustainability Assurance (ISSA) 5000, General Requirements for Sustainability Assurance Engagements, the IAASB has focused on supporting the adoption and implementation of ISSA 5000.
- Most recently, the IAASB has published a frequently asked questions (FAQ) document on the application of materiality. In addition, extensive implementation support materials are available on the ISSA 5000 focus area webpage.
The IAASB is continuing to develop additional FAQs covering aspects of sustainability assurance engagements, with publication planned throughout Q3 and Q4 2026. These FAQs will address implementation issues and questions arising from stakeholder feedback. A joint IAASB-IESBA FAQs are also planned for publication in Q4 2026.
The IAASB also continues to monitor ISSA 5000 adoption, which is available on the IAASB website.
To support effective and consistent ISSA 5000 implementation, the IAASB invites stakeholders to submit implementation questions or matters for the IAASB’s consideration. To access the submission form, see “Submit Questions & Feedback on ISSA 5000 Implementation” on www.iaasb.org/ISSA5000.
Updated July 2026
In May 2026, the IAASB issued proposed International Standard on Review Engagements (ISRE) 2410 (Revised), Review of Interim Financial Information Performed by the Independent Auditor of the Entity’s Annual Financial Statements as an exposure draft for public comment. The consultation period will end on September 3, 2026.
The proposed revised standard, in a clarified format, aims to set a global baseline for consistent performance of high-quality interim review engagements, by:
- Setting clear requirements that include foundational principles of an interim review engagement, and more prescriptive requirements where necessary for clarity, to support consistency of application, or for ease of compliance.
- Strengthening or extending requirements related to going concern, fraud, group audits and non-compliance with laws and regulations, in recognition of the public interest associated with these areas; and
- Modernizing requirements related to the auditor’s interim review report, including a format consistent with the report on audited financial statements. The proposed interim review report also has a clearer description of an interim review engagement and its differences with an audit engagement, and a new section for reporting on going concern, in the context of a limited assurance engagement.
Stakeholders are encouraged to submit responses to the consultation, using the Response Form available on the IAASB website.

Updated July 2026
In February 2026, the IAASB launched a public consultation survey as part of its post-implementation review on International Standard on Auditing (ISA) 540 (Revised), Auditing Accounting Estimates and Related Disclosures. This survey closed on June 15, 2026.
The survey sought input from a broad range of stakeholders and included tailored questions to reflect the perspectives and experiences of various stakeholder groups. This approach was designed to help ensure that respondents answer questions relevant to their role and interaction with ISA 540 (Revised) or its outputs.
The survey focused on three principal areas:
- Overall views on ISA 540 (Revised), including those related to non-authoritative guidance and tools 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).
The project team is considering comments received along with input from additional targeted outreach and other information gathering to develop views and recommendations for the IAASB’s consideration in September and December 2026.
For further information, visit the Post-Implementation Review of ISA 540 (Revised) project page.
Updated July 2026
In December 2025, the IAASB and the International Ethics Standards Board for Accountants (IESBA) approved a joint stakeholder survey as a first step in the IAASB’s and IESBA’s process to develop their respective Strategies and Work Plans for 2028–2031. The joint stakeholder survey was open for public comment from January to May, 2026. 108 survey responses were received from a diverse range of stakeholder groups and geographies.
In June 2026, the IAASB reviewed a high-level overview of survey responses, as did the IESBA, including the preliminary quantitative ratings of environmental trends.
The next IAASB discussion will be in September 2026, when the IAASB will consider a full analysis of survey responses. The IAASB will also continue to deliberate on the development of a consultation paper and coordinate with the IESBA to ensure a parallel process for the two Boards strategies and work plans.
Updated March 2026
In March 2026, the IAASB expressed support for IAASB staff researching and gathering information on subject matter-specific assurance engagements other than sustainability with a two-fold objective:
- To understand subject matter-specific assurance engagements being undertaken or emerging, whether mandatory or voluntary, and their potential global relevance. This includes updating the IAASB’s information on assurance related to XBRL and its potential priority as a reserve topic that could be elevated to the current work plan.
- To identify the standards used when these engagements are undertaken, including existing jurisdictional standards or guidance.
The primary focus of this information gathering is identifying and understanding assurance engagements that are not specific to a single or only a few jurisdictions, and that are not linked to a narrow topic, such as specific regulatory requirements. It is also important to understand the extent to which such engagements are related to general-purpose external reporting of entities because this is relevant in indicating proximity to the IAASB’s remit.
Initial feedback and views will be presented for discussion at the IAASB’s September 2026 meeting.
Updated July 2026
At its June 2026 meeting, the IAASB received its semi-annual monitoring update under Component 3 of the IAASB’s Technology Position and discussed proposed changes to the Technology Catalog. This update to the Technology Catalog was the first since the IAASB’s approval, in March 2026, of the IAASB’s Technology Catalog Process: Approach to Addressing Technology-Related Matters.
The approach formalizes how the IAASB identifies, evaluates, and responds to technology-related matters within its remit, including how such matters are included in the Technology Catalog, how their status is documented, and how the IAASB’s preliminary direction on actions is recorded.
The proposed changes to the Technology Catalog were informed by the IAASB’s monitoring activities, including input from the Technology Advisory Network, jurisdictional standard setters, the Stakeholder Advisory Council, outreach, research, and coordination with IAASB project teams. The changes include structural and framing refinements to improve readability and transparency, clearer descriptions of how matters are addressed through active IAASB projects or workstreams, and the introduction of new matters identified through monitoring activities.
The proposed new matters include audit challenges associated with entities with activities in the crypto-asset ecosystem; audit implications of increasingly sophisticated cybersecurity threats affecting entities; AI and cybersecurity assurance; and technology-related application questions that may arise in sustainability assurance engagements as ISSA 5000 begins to be applied. The IAASB also considered whether this monitoring update suggested any need to recalibrate aspects of the broader Technology Position.
Following the IAASB’s June discussion, Version 3 of the Technology Catalog has been published as a PDF, with a digital version to follow in Q3.

Updated July 2026
At its June 2026 meeting, the IAASB discussed the proposed roadmap for a Technology Quality Management series of guides. The proposed roadmap builds on the initial roadmap included in the Action Plan approved by the IAASB in March 2026 (Agenda Item 3-F) and is intended to make that plan more concrete and actionable. The discussion addressed related foundational considerations, including the proposed scope, guide structure, recurring content elements, sequencing, and approach to the IAASB’s consideration and approval of the guides.
Following approval of the Action Plan in March, the Technology Quality Management Expert Group was established to provide structured input into the development of the guide series. The Expert Group met twice in Q2 2026, and input from those meetings informed the IAASB’s deliberations on the proposed roadmap at its June 2026 meeting.
At its September 2026 meeting, the IAASB plans to discuss revisions to the roadmap and draft content for selected guides.
