my supplier not show the details of Credit note issue by him in his GSTR -1 . so now can I show in my gstr -1 the debit not issue by us. or what other option we have. please explain.
1) Showing such transactions in your GSTR1 is not appropriate.
2) Instead, you deduct such difference from input tax credit while filing GSTR3B.
Since you are availing ITC which is less than that declared by the supplier, there is no loss of revenue for govt.
