October 2026 Calendar of GST Return Filing Due Dates
The government announces GST return filing due dates from time to time to maintain taxation in line with respective clearances. Additionally, the primary objective is to inform taxpayers about the GST return filing due dates, thereby preventing them from incurring any penalties or interest. We are offering a GST due dates calendar for October 2026 to all registered taxpayers under the indirect tax regime to help them stay aware of the filing periods for their GST returns.
As GSTR-1 and GSTR-3 B are filed monthly, we need regular updates/notifications based on the GST due dates calendar to avoid interest and penalty. Also, there is GST CMP 08 for the composition scheme dealers, but it has to be filed every quarter, lowering the need for regular updates on the GST due date filing calendar.

Interest on Late GST Payment and Penalty for Missing GST Return Due Dates
The GST Council has decided to levy an interest of 18 per cent on the late payment of taxes under the GST regime. The interest would be levied for the days for which tax was not paid after the due date. You can read more details of the GST penalty provision in Chapter 10, Part 50, at this link https://cbec-gst.gov.in/CGST-bill-e.html
Let’s understand this by an example: If the total tax liability of a person is Rs. 1,000 and doesn’t pay tax continuously for a few days after the due date, then the interest amount will be calculated as 1000*18/100*1/365= Rs. 0.49 per day at approx. So, the person will have to pay this much interest each day after the due date.
In case if a taxpayer does not file his/her return within the due dates mentioned above, he shall have to pay a late fee of Rs. 50/day i.e. Rs. 25 per day in each CGST and SGST (in case of any tax liability) and Rs. 20/day i.e. Rs. 10/- day in each CGST and SGST (in case of Nil tax liability) subject to a maximum of Rs. 5000/-, from the due date to the date when GST forms, GSTR 1 GSTR 3B GSTR 4 GSTR 5 GSTR 6 GSTR 9 are actually filed.

As I have forgotten to mention the exempt purchase in my 3B return in FY 2017-18. now, what should i do now plz help…?
Fill the details in next month return.
We have been filing GSTR-1 monthly basis. But the thing is we been have filing GSTR-1 after filing the GSTR-3B. Actually, as per the due dates, GSTR-1 is supposed to be filed before 10th of subsequent month. But we are filing after GSTR-3B filed. So, please suggest, what will be the impact on late filing of GSTR-1?. Thanks
In case of late filing, late fees to be paid from due date of filing till date of filing at Rs. 25 per day.
Hello,
Is it possible to pay GST for August 2017 now? Will it attract late fees?
Yes, you can pay the GST with applicable interest. Late fees would be attracted if GST returns are not filed for the respective month.
Hey Subodh,
Can you tell me how much will be the late fees, if someone doesn’t file the GST return from August 2017, who falls under the category of quarterly return? And yes in this time duration there were months when no inward and outward supply was done. Please, it will be really great of you if you can at least tell the approx value.
In case there is no data then you have to file Nil return with late fees. Late fees shall be Rs, 10 per day each in CGST and SGST and it shall be levied from the due date of filing till actual date of filing. So calculate accordingly quarter wise but such late fees shall be maximum Rs. 5000 for a tax period.
Hi Subodh,
Could you please quote me the notification/circular/order issued by CBIC based on which you mentioned that the due date of FORM GSTR-3B for July, 2018 to be 20 August, 2018? Thanks in advance.
Official notification has not been issued regarding the due date of GSTR-3B for the month of July’18. You can visit the website http://www.gst.gov.in and check the important dates section. It has been specified there.
