GST Return Filing Due Dates: A 2026 Calendar for Small Business
The main GST returns, who files what, monthly vs quarterly schemes, and how to never miss a due date.
Missing a GST return means late fees and interest — and it blocks your buyers’ credit. Knowing which returns you file and when keeps you clear. Here is the landscape and how to stay on time. This is general information, not tax advice — GST rules, rates and thresholds change and vary by case, so confirm specifics with a qualified professional or the official GST portal.
The main returns
- GSTR-1 — outward supplies (monthly or quarterly)
- GSTR-3B — summary of tax liability and ITC
- CMP-08 — for composition dealers
- GSTR-9 — annual return, where applicable
Monthly vs quarterly (QRMP)
Smaller taxpayers can opt into the QRMP scheme to file quarterly with monthly tax payment. Your frequency determines your due dates, so confirm yours on the GST portal.
Never miss a date
Keep your billing reconciled through the month so returns are just an export, not a scramble. MyGroce keeps GSTR-1 and GSTR-3B-ready reports current, so filing is quick and on time.
