Thank you for the super quick reply Bhavana! 
could you pls also guide about filing this credit note in return? Do I just need to enter the credit note details in the gstr1? Any changes in 3b filing? Also, any deduction to be made in total taxable value while filing return? 
thank you for help! 

Thanks again Bhavana! Very nicely explained. 

hi bhavana,

just realised that the invoice is of October month of which I have included and filed in gstr1 this month. I will have to file gstr3b and make payment. As the invoice is cancelled is it possible to amend the filed gstr1 and not make the payment in 3b? Or is it I will have to pay the gst in 3b and raise a credit note only.

	NP Mackie, Hi Namrata, In case credit notes are more than tax invoices in any particular month, then the credit notes can be reported in GSTR 1 of the same month and report it in 3B in the month when there is a tax liability.Hope this clarifies.ThanksBhavana CA

Isnt the 3b automatically calculated based on filled gstr1? So I guess if I put the credit note in gstr1 then the total taxable value and tax liability is auto calculated and goes down in 3b. Pls correct if my understanding is wrong.
