GST Return Due Dates in India (Monthly & QRMP)

Here are the main GST return due dates as of 2026 (always confirm the live dates on gst.gov.in or with your CA, since they change and are often extended):

• GSTR-1 (monthly): 11th of the next month.
• GSTR-1 (QRMP, quarterly): 13th of the month after the quarter.
• GSTR-3B (monthly): 20th of the next month.
• GSTR-3B (QRMP, quarterly): 22nd or 24th after the quarter, by state group.
• CMP-08 (composition): 18th after the quarter.
• GSTR-9 (annual): 31st December of the next financial year.

What are the GST return due dates right now?

GST return due dates are the deadlines by which a registered business must file each periodic return. The date depends on which return it is and whether you file monthly or under the QRMP (Quarterly Return, Monthly Payment) scheme.

The figures above are the standard dates as of 2026. They are not carved in stone. The government revises and extends due dates regularly, sometimes state-by-state during disruptions. So treat this as a planning reference and verify each deadline on the official portal before you file.

The returns most small businesses deal with

• GSTR-1: Your outward supplies (sales) return. See our GSTR-1 filing guide.
• GSTR-3B: Your summary-and-payment return.
• CMP-08: For composition scheme dealers.
• GSTR-9: The annual return for larger taxpayers.

If you are unclear on how GSTR-1 and GSTR-3B differ, read GSTR-1 vs GSTR-3B. The simple version: GSTR-1 reports invoice detail, GSTR-3B is the summary where you pay.

Monthly filers vs QRMP filers

Your due dates depend on which track you are on. QRMP lets smaller businesses file quarterly while still paying tax monthly.

Monthly filing

If your aggregate annual turnover is above the QRMP threshold (₹5 crore as of 2026), or you simply opt for monthly, you file every month:

• GSTR-1: by the 11th of the following month.
• GSTR-3B: by the 20th of the following month.

QRMP filing (Quarterly Return, Monthly Payment)

If your turnover is up to ₹5 crore (as of 2026), you can opt for QRMP. You file returns once a quarter but still pay tax each month.

• GSTR-1 (quarterly): by the 13th of the month after the quarter ends.
• GSTR-3B (quarterly): by the 22nd (Category X states) or 24th (Category Y states) after the quarter.
• Monthly tax payment: via PMT-06 by the 25th of each of the first two months of the quarter.
• IFF (optional): upload B2B invoices monthly so your buyers get timely ITC.

The 22nd-vs-24th split is by state group, so check which group your state falls in. As always, confirm the live dates on gst.gov.in.

Which track suits you?

• Choose monthly if your buyers need monthly ITC and your volumes are high.
• Choose QRMP if you are small, want fewer filings, and can manage the monthly tax payment.

Late fees and interest if you miss a deadline

Missing a GST deadline costs money in two ways: a late fee for filing late, and interest on any tax you paid late. Both are set by notification and have changed over the years, so the amounts below are indicative as of 2026, not guaranteed; verify the current rates on the official portal or with your CA.

Late fee (hedge)

• Per-day late fee typically applies for each day past the due date, split between CGST and SGST, subject to a maximum cap.
• Nil returns usually attract a lower per-day fee with a lower cap.
• The exact daily amount and the cap depend on your turnover slab and current notifications.

Interest (hedge)

• Interest is charged per annum on the net tax paid in cash after the due date.
• A higher interest rate can apply to excess or wrongly availed ITC.
• Interest runs from the day after the due date until you actually pay.

There is also a knock-on effect: if you do not file GSTR-3B, the portal can block your GSTR-1, and prolonged non-filing can lead to suspension of your registration. For the sales-return specifics, see GSTR-1 due dates and late fees.

How to never miss a GST deadline

The cost of a missed return is rarely the late fee alone; it is the lost buyer credit, the notices, and the scramble. A simple system prevents all of it.

1. Map your own calendar. Write down your exact return dates based on monthly vs QRMP and your state group.
2. Set reminders a week early. Aim to file before the date, not on it, so portal slowdowns near deadlines do not catch you.
3. Keep invoices clean all month. Most delays come from messy data, not the filing itself.
4. Reconcile ITC against GSTR-2B before GSTR-3B so you are not stuck on the due date.
5. File Nil returns too. A zero-activity period still needs a return.
6. Confirm extensions. Before assuming a deadline moved, verify it on gst.gov.in.

The best defence is data that is already return-ready. Invodo keeps every invoice GST-correct as you raise it, separates B2B and B2C, applies the right CGST/SGST/IGST, and exports clean GSTR-1 and GSTR-3B data so filing is a quick check, not a monthly fire drill.
