Singapore reporting cycles and business-day rules
Singapore business-day cycles align with CPF contributions due by the 14th of the following month, IRAS GST quarterly returns due by the last day of the month after each quarter-end, and MAS-supervised SGD clearing. The G3 (FAST) and PayNow systems operate around the clock; the high-value MEPS+ system clears same-day. ACRA annual-return filings are due within seven months of the financial year-end. The MAS Monetary Policy Statement publishes semi-annually in April and October, with associated SGD-NEER band updates that move FX desks.
