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:
That’s not an exhaustive list, but it does give an indication of how much work will be involved. And it’s happening at the same time as the AICPA extensive new Statements on Quality Management Standards (SQMS) requirements are coming into effect.
