China reporting cycles and business-day rules
Chinese business-day cycles align with STA (State Taxation Administration) monthly VAT and corporate income tax deposits due by the 15th of the following month for most regimes, plus annual corporate income tax returns due May 31 for calendar-year filers and the annual Individual Income Tax (IIT) reconciliation from March 1 to June 30. The PBoC operates CNAPS as the high-value RTGS system on bank business days; CIPS handles cross-border RMB settlement. Spring Festival and National Day Golden Weeks each close banks and exchanges for 7-8 days, with State Council-gazetted make-up working Saturdays surrounding each holiday. SAFE (State Administration of Foreign Exchange) governs capital-account flows and approval windows.
