Answer

"where a recipient fails to pay to the supplier of goods or services or both, other than the supplies on which tax is payable on reverse charge basis, the amount towards the value of supply along with tax payable thereon within a period of one hundred and eighty days from the date of issue of invoice by the supplier, an amount equal to the input tax credit availed by the recipient shall be added to his output tax liability, along with interest thereon, in such manner as may be prescribed"
Therefore if payment of supply is not made within 180 days then the credit is to be reversed by adding it in output tax liability.
There is no facility available to the supplier to reverse the tax paid or take refund of it.
The Credit note can be issued by the supplier only if the goods are returned or on execution of certain acts decided at the time of supply. (Reply dt.05/07/2018)
