The China Securities Regulatory Commission and China’s Ministry of Finance issued revised rules governing how accounting firms file to provide securities services, aiming to strengthen oversight and standardise filing practices. The update allows firms to submit filing information through either regulator’s online system, with automatic data sharing intended to eliminate duplicate submissions. Accounting firms may file via the Ministry of Finance’s unified supervision platform for the certified public accountant profession or the China Securities Regulatory Commission’s government services filing system, submitting in one system and confirming in the other. The revised procedures also set out workflows for first-time filings (including auto-populated data and handling of inconsistencies), filings for significant changes after initial registration (including cases where updates follow procedures with provincial-level or higher finance departments), and annual filings, which must be completed by 31 May each year.
