ADDITIONAL GUIDANCE: Since this blog was first published, the PCAOB released two new guidance documents. The Nov. 26 updates can be found here: An additional overview of the requirements of QC 1000 and staff guidance for firms about how to comply with the standard. This document provides additional staff insights on scope and applicability, responding to engagement deficiencies, and documentation for AS 2901, Responding to Engagement Deficiencies After Issuance of the Auditor’s Report. The Public Company Accounting Oversight Board (PCAOB) recently announced a new set of quality control standards designed around a risk-based approach. And there’s only one year to design and implement them. The PCAOB’s new QC 1000 standard is more than two decades in the making, as it replaces the quality control standards it adopted on an interim basis back in 2003 from the American Institute of Certified Public Accountants (AICPA). The new standard is intended to make independent registered public accounting firms significantly improve their quality control (QC) systems. QC 1000 applies to all PCAOB-registered member firms, with more extensive requirements for those that audit more than 100 issuer clients annually. It has been approved by the U.S. Securities and Exchange Commission (SEC) and goes into effect on December 15, 2025. The new requirements and the work required to implement them will be extensive, and the larger public accounting firms require external oversight of the QC system. Therefore, it is strongly recommended that firms do not put it off until the last minute. At its core, the new standard is intended to enable firms to identify their specific risks and design a quality control system including policies and procedures to guard against those risks. The overall goal is to establish what the PCAOB calls “a continuous feedback-loop for improvement.” In this, the new standard differs from the International Auditing and Assurance Standards Board’s (IAASB) International Standard on Quality Management No. 1 (ISQM 1) and the AICPA Statement on Quality Management Standards No. 1 (SQMS 1). An extensive but not comprehensive comparison document of the three standards may be found here, but is presented only as a reference tool. New requirements QC 1000 has requirements that do not appear in other QC standards. They can be more prescriptive or more specifically tailored to the U.S. legal and regulatory environment. There are 10 main areas in which the QC 1000 standards go beyond other, existing standards. These are: Evaluation and Reporting: QC systems must be evaluated annually and reported to the PCAOB. They must be certified by specific individuals with responsibility and accountability for the firm’s QC system. Governance and Leadership: Firms must create and maintain clear lines of responsibility and supervision. Larger firms must have outside oversight and a confidential complaint system. Ethics and Independence: Quality objectives must be tailored to the U.S. regulatory environment. Larger firms must implement an automated system for identifying securities investments that could impair independence. Monitoring and Remediation: QC 1000 divides monitoring into engagement and QC system levels. Engagement and QC deficiencies are defined, including requirements for their determination. Larger firms must (and smaller ones should) monitor in-process engagements. Quality Objectives: The firm’s personnel must comply with its policies and procedures Information and Communication: Quality objectives for communication with external parties are established at the firm and engagement level. Communication of the firm’s QC system’s policies and procedures must be communicated in writing. Resources: The firm’s personnel must adhere to standards of conduct. Policies and procedures must address both enumerated and circumstance-specific competencies. Mandatory training, licensure and technological resource requirements are established Risk Assessment Processes: Quality risks must be identified and assessed annually. Roles and Responsibilities: A single person must be assigned responsibility for each role and responsibility in the QC 1000 standard. Documentation: With respect to the QC system’s operation, documentation that allows an experienced auditor to evaluate the operation of quality responses must be provided. Documentation must be retained for at least seven years. That’s not an exhaustive list, but it does give an indication of how much work will be involved.
