Missing a GST due date is rarely about not knowing the rule — it is usually about not having a single reliable place to track it.
Core Monthly Returns

| GSTR-3B | Summary return & tax payment | 20th of following month |

Annual Filings
- GSTR-9 — Annual return, generally due 31 December following year-end

The cheapest GST filing is the one done on time — the cost of being late compounds in ways not always visible until audit time.
