I am a service provider. I have raised invoice against the service which i have rendered on 14.03.2018. But by mistake i have shown more tax value than the invoice in gstr 1. Accordingly i have issued credit note for the difference value on 12.09.2018. And incorporate this credit note in gstr 1 return of December month 2018. Is this correct to regularise my mistake? if no then plz guide how to correct.
I have read that credit note should be incorporated in return of september or annual return whichever is earlier. In my case i have incorporated it in Dec 2018. Is this wrong??
thanks in advance.
