Reversal of input tax

if it relates to FY 2018-19 or FY 2019-20, then reverse CGST and SGST claimed in mext month and also availing IGST. As per law, interest is applicable since it is wrong availment of credit.

Sir it relates FY 2017-18

IF YOU HAVEN'T FILED GSTR -9 OR 9C (SUBJECTIVE) YOU CAN ALTER THE AMOUNT OF THE HEADS AND PAY IT IN DRC - 03 ON THE OTHER SIDE IF U HAD ALREADY FILED THE RETURN ONLY WAY IS TO PAY THE AMOUNT WIT 24% INTEREST , AND KEEP IT AS A RECORD FOR FUTURE PROCEEDINGS (IF MADE).

If it relates to FY 2017-18, then due date for amendment is already crossed. no more changes can be made. you have to make payment as wrong availment of credit either GSTR-9 or 9C and pay theough DRC-03. If that also filed then make payment with DRC-03 as voluntary payment along with interest if utilised already.

IF IT RELATES TO FY 17-18 I THINK WE COULD CHANGE IN GSTR 9
