GSTR-1, GSTR-3B, QRMP, CMP-08 and the annual GSTR-9 deadlines in plain language — plus a month-by-month 2026 calendar for the two returns almost every shop files.

These are the standard statutory due dates. The CBIC can extend or change any deadline by notification, and this page is a plain-language guide, not tax advice — always confirm the current date on the GST portal (gst.gov.in) or with your accountant before filing.

Frequently asked questions

What is the GSTR-1 and GSTR-3B due date in 2026?

For a regular monthly filer, GSTR-1 is due on the 11th of the next month and GSTR-3B on the 20th of the next month. So sales for January 2026 are reported in GSTR-1 by 11 February and GSTR-3B by 20 February. These are the standard statutory dates; the government can extend them by notification.

What are the QRMP scheme due dates?

If your turnover is up to ₹5 crore and you opted into QRMP, you file quarterly: GSTR-1 by the 13th of the month after the quarter, and GSTR-3B by the 22nd (category-X states) or 24th (category-Y states). You still pay tax monthly via PMT-06 by the 25th.

When is the annual GST return (GSTR-9) due?

GSTR-9 (and GSTR-9C where applicable) for a financial year is due by 31 December of the following year. So the annual return for FY 2025-26 is due by 31 December 2026. Composition dealers file GSTR-4 annually by 30 June instead.

What happens if I miss a GST filing deadline?

You pay a late fee for each day of delay plus interest on any unpaid tax, and your buyers may not get their input tax credit on time. Filing even a nil return on time avoids the late fee, so it is worth setting a reminder for the 11th and 20th every month.

Can Jhalmuri.ai remind me about GST deadlines?

Yes. Jhalmuri.ai can set up an AI assistant that reminds you before each filing date on WhatsApp and helps you keep your sales records ready. Message Rakesh on WhatsApp to see how it works for your shop.
