Debit note in gstr1 & 3B

Amend GSTR1 to reverse the liability. Reduce input tax credit from GSTR3B (if not already done) and pay interest if applicable.

Tax liability is decrease in gstr 3b and also my itc reversal is not change as it show credit note , as it will be ok right? But you said pay interest if applicable how? I don't want to give interest, what will be the consequences after that? Please explain

1) I didn't get your first query.

2) Regarding interest, if such C/N was raised by the supplier during a month and reversal has also been considered in the same month itself, then no interest would be applicable.

3) If you opt not to pay interest (when applicable), you need to pay if you get a notice from the department.
