The monthly items (Challan 281, GSTR-1, ECR, ESIC challan and GSTR-3B) are for September 2027; the quarterly and annual items say which period they cover. Each item below says who it applies to, so a business can skip what does not concern it: a composition dealer, a QRMP filer and a monthly filer each have different GST dates, and the ROC items depend on whether the business is a company or an LLP.
The dates are the statutory ones. A date that falls on a Sunday or a holiday is shown as the law fixes it, not moved; an extension or fee waiver notified by CBDT, CBIC or the MCA is applied, and the item's note names the circular or notification. For your own business, the reminders and the filing can be handled by our expert team.
