Question – I have filled GSTR-3B of November, but some of the bills got canceled due to late despatch of goods, how can I get back the Tax paid of those bills in GSTR-3B of Nov.?
Answer – GSTR3B once filed cannot be revised as of now. But you can simply correct the details in GSTR-1. Show the correct amount of output tax in GSTR1 for the same month. The difference of excess tax paid in GSTR3B will get credited to your ledger. You need to make sure that the bills were not provided to customers and if has been provided then they should not avail the credit in its respect. If they have taken ITC in their GSTR3B then you need to issue Debit note.
