GST return due date: one page for GSTR-1, GSTR-3B, and GSTR-9
The standard due dates for the common GST returns on one page: GSTR-1 on the 11th, GSTR-3B on the 20th with the QRMP split, and the annual GSTR-9 and GSTR-9C, plus how one return feeds another and how to confirm a change from CBIC.
In this guide
For monthly filers, GSTR-1 is due on the 11th of the following month and GSTR-3B on the 20th. Under the QRMP scheme, quarterly GSTR-3B is due on the 22nd or 24th of the month after the quarter, depending on your state group, with tax paid monthly through a PMT-06 challan. The annual return GSTR-9, and the reconciliation statement GSTR-9C where it applies, are due on 31 December of the following financial year. Confirm any change through a CBIC notification before you rely on a new date.
What the GST return due date covers
There is no single GST return, so there is no single due date. A regular taxpayer files an outward supplies return, a summary return that settles tax, and an annual return once a year. Each has its own date, and the one you miss is usually the one you were not watching.
This page puts the standard dates for the common returns in one place. The dedicated guides for GSTR-1 and GSTR-3B go deeper on each; use this page to see how they sit together across the year.
Standard due dates for the common GST returns
The table maps the recurring due dates. QRMP quarterly GSTR-3B dates depend on your state group, explained in the next section.
| Return | Who and how often | Due date |
|---|---|---|
| GSTR-1 | Monthly filers | 11th of the following month |
| GSTR-1 (QRMP) | Quarterly filers | 13th of the month after the quarter |
| GSTR-3B | Monthly filers | 20th of the following month |
| GSTR-3B (QRMP) | Quarterly filers | 22nd or 24th of the month after the quarter, by state group |
| PMT-06 challan | QRMP monthly tax payment | 25th of the following month |
| GSTR-9 and GSTR-9C | Annual, by turnover threshold | 31 December of the next financial year |
The QRMP quarterly GSTR-3B date is the 22nd for the broadly southern and western state group and the 24th for the broadly northern and eastern group, based on your principal place of business. The GSTR-3B guide sets out the two groups in full.
Monthly, quarterly, and annual returns
The returns fall into three timing tracks, and it helps to hold them apart.
- Monthly or quarterly outward supplies (GSTR-1): reports your invoice-level sales. It does not pay tax by itself.
- Monthly or quarterly summary (GSTR-3B): declares the net tax and pays it. This is the return that carries interest and late fee risk.
- Annual return (GSTR-9 and GSTR-9C): a yearly consolidation and, above a turnover threshold, a reconciliation with your audited accounts.
Whether you file GSTR-1 and GSTR-3B monthly or quarterly depends on whether you opted into QRMP. The annual return sits on top of both tracks regardless.
How one return feeds another
The returns are not independent forms filed in isolation. GSTR-1 reports the invoices; those invoices flow into your recipients' input tax credit and are reflected in your own GSTR-3B liability. GSTR-3B then pays the tax. GSTR-9 consolidates the year and should reconcile with what the monthly or quarterly returns already reported.
The practical effect is that a late or wrong GSTR-1 does not stay contained. It affects the credit your customers can claim and it creates a mismatch you have to explain at the annual return. Filing GSTR-1 accurately and on time keeps the later returns clean.
How CBIC extensions actually work
GST return dates are sometimes extended, but almost always narrowly: for a particular state, district, or period hit by a disruption. When an extension is real, you should be able to do all three:
- Find a CBIC notification with a number and date.
- Open it from the official CBIC-GST portal.
- Read who it covers, which return and period, and which state or district it names.
A general "due date extended" message with no notification number should not change your filing plan. Broad, all-India extensions are rare and always land as a notification you can open.
How to confirm your own due dates
- Log in to the GST portal and open the returns dashboard for the period. The portal shows the applicable due date for your profile.
- Confirm whether your profile is monthly or QRMP under the return settings.
- For any rumoured extension, check the CBIC-GST portal notifications for a matching number and PDF.
- Read the GST returns help pages if you are unsure which return applies to your case.
Common mistakes with GST return dates
- Watching the monthly dates when you are actually a quarterly QRMP filer, or the reverse.
- Filing GSTR-3B on time but forgetting the earlier GSTR-1, which affects your customers' credit.
- Forgetting the monthly PMT-06 challan under QRMP and facing interest even before the quarterly return is due.
- Treating the annual GSTR-9 as optional when your turnover crosses the filing threshold.
- Assuming a forwarded extension applies to you without a CBIC notification number.
Where Complied AI fits
GST return-date changes move through CBIC notifications, often state-specific and easy to miss in a rumour cycle. Complied AI keeps CBIC and GST notifications in one feed so you can open the source document behind a change instead of trusting a forward. When you need the rule itself, read the CGST provision next to the update rather than only the headline date.

Common questions
What is the GST return due date for monthly filers?
For monthly filers, GSTR-1 is due on the 11th of the month following the tax period and GSTR-3B on the 20th. For example, the returns for June are due on 11 July and 20 July.
What are the GST return due dates under the QRMP scheme?
Under QRMP, GSTR-1 and GSTR-3B are filed quarterly. Quarterly GSTR-3B is due on the 22nd or 24th of the month after the quarter based on your state group, while tax is paid monthly through the PMT-06 challan by the 25th of the following month.
When is the GSTR-9 annual return due?
GSTR-9, the annual return, and GSTR-9C, the reconciliation statement where it applies, are generally due on 31 December of the year following the financial year. The requirement to file depends on turnover thresholds set by notification.
Can GST return due dates be extended?
Yes, but only through a CBIC notification, often for a specific state, district, or period. Confirm the notification number and open the PDF before you treat any extension as real.
