Whether Input Tax credit should be reversed in case of non-payment of consideration to supplier as per Rule 37 of the CGST Rules, 2017?

Yes, where the value of the supply along with the tax, has not been paid to the supplier within 180 days from the date of issue of invoice, the input tax credit availed by the recipient will be added to the output tax liability of the recipient. The recipient will have to furnish the details of the supply in Form GSTR-2 for the month immediately following the period of 180 days from the invoice date and will be liable to pay interest from the date of availment of credit till the date of addition to the output tax liability.
