In August 2025, the PCAOB announced a 1-year delay in the effective date for QC 1000,
A Firm鈥檚 System of Quality Control
, and other related amendments to PCAOB standards, rules, and forms adopted on May 13, 2024. These requirements will now take effect on December 15, 2026. The Board also deferred the date on which certain existing rules and standards will be rescinded. Please note that as of the date of this communication, the PCAOB has neither revised nor proposed revisions to the text of the new or amended standards, rules, or forms as adopted. The PCAOB's prior position on early adoption has not changed: registered firms may choose to comply with QC 1000 before the effective date. However, firms are not permitted to report to the PCAOB on the evaluation of the quality control system before the effective date.
