Add the dates to your calendar

Choose what you file, and add just those dates to your calendar app. Each one says who it’s for, like “GSTR-3B due (Oct 2026): monthly filers”. When we add or change a date, your calendar updates by itself, though not straight away. A date stays in your calendar until the end of the month after it’s due.

Using Google Calendar? Open this page once on a computer and add your calendar there: Google’s phone app can’t add a calendar from a link. It then shows in the app on your phone too (if it doesn’t, check the app’s sync settings). You may not get the reminders there: see Reminders.

There’s a calendar for each kind of filer. Add the one for what you file:

Add it to Google Calendar on a computer: Google’s phone app can’t add a calendar from a link. The Outlook link is for an Outlook.com account. If a link doesn’t work, paste the address under “From URL” in Google Calendar, or “Subscribe from web” in Outlook.

Reminders

Each date comes with a reminder at 9 am, 2 days before it’s due. Whether you see it depends on your calendar app:

  • Apple Calendar on a Mac: when you subscribe, find “Remove” and make sure the Alerts box next to it is unticked. If it’s ticked, the reminders are removed.
  • Apple Calendar on an iPhone or iPad: in Calendar, tap Calendars, then the info button next to this calendar, and check that Event Alerts is on.
  • Google Calendar: you may not get them, so don’t rely on them. Google’s help explains notification settings only for calendars you own.

How it works

Every GST return has a due date set by law: in the CGST Act, the CGST Rules or a notification from CBIC (the Central Board of Indirect Taxes and Customs). We work out each date from that source, list it here with who files it, and say when we last checked it. The sources are listed at the end of this page.

The GST portal’s home page, gst.gov.in, also shows the next dates for the main returns, in its Upcoming Due Dates box.

What the forms are

  • GSTR-1: the details of your sales.
  • IFF (Invoice Furnishing Facility): an optional way for quarterly filers to report sales to registered buyers for the first two months of a quarter.
  • GSTR-3B: a summary of your sales, purchases and tax, filed with the tax payment.
  • PMT-06: the form quarterly filers use to pay the tax for the first two months of a quarter.
  • CMP-08: the composition taxpayer’s quarterly statement, filed with the tax payment.
  • GSTR-4: the composition taxpayer’s annual return.
  • GSTR-9: the annual return of a regular taxpayer. Larger businesses also file GSTR-9C with it: a statement that compares the value of the sales in their GSTR-9 with their audited accounts.
  • GSTR-5, GSTR-6, GSTR-7 and GSTR-8: the returns of non-resident taxable persons, Input Service Distributors, those who deduct TDS, and e-commerce operators who collect TCS.

A worked example

For example, take a shop in Maharashtra that files every quarter in the QRMP scheme. Maharashtra is in State group 1, so its GSTR-3B is due on the 22nd. For Oct to Dec 2026, its dates are:

  1. By : IFF for Oct 2026 (optional)
  2. By : PMT-06 for Oct 2026 (tax payment)
  3. By : IFF for Nov 2026 (optional)
  4. By : PMT-06 for Nov 2026 (tax payment)
  5. By : GSTR-1 for Oct to Dec 2026
  6. By : GSTR-3B for Oct to Dec 2026

A shop in Delhi, in State group 2, has the same dates, except that its GSTR-3B is due by .

To get these dates in a calendar, the shop in Maharashtra adds the one for quarterly (QRMP) filers in State group 1: see Add the dates to your calendar.

Questions

Why does my calendar still show an old date?

Calendar apps check a calendar you’ve added only every few hours. After we change a date, Google Calendar, Apple Calendar or Outlook can take 12 to 24 hours, sometimes longer, to show the change.

If your calendar and this page don’t match, trust this page over your calendar app. The official dates are on the GST portal, gst.gov.in.

What is the QRMP scheme?

QRMP stands for Quarterly Return Monthly Payment. You file GSTR-1 and GSTR-3B once a quarter instead of every month, but you still pay tax every month.

Smaller businesses can choose it on the GST portal. Notification No. 84/2020-Central Tax sets out who can.

What if I miss a due date?

File as soon as you can. For most returns a late fee is charged for each day you’re late, and interest is charged on tax paid late (sections 47 and 50 of the CGST Act).

Both add up day by day (the late fee up to a maximum), so the sooner you file, the less you pay.

Can a due date change?

Yes. The government sometimes extends a due date with a notification, at times close to the date.

When that happens, we change the date on this page and in our calendars, and say which notification extended it. So check this page a few days before you file.
