This discussion clarifies the application of GST on bad debts. While Input Tax Credit (ITC) must be reversed if a supplier isn't paid within 180 days, this rule applies to the recipient, not the supplier. For suppliers to reverse GST on bad debts, they typically need to issue a credit note, which is usually only possible for goods returned or rate differences. Ultimately, the consensus is that bad debts themselves don't attract GST as the supply was legally made; it's a payment issue.
Bad debts happens only customer didn't make payment.if we didn't pay to supplier within 180 days itc reverse applicable.in this case GST should have been paid and need not pay again.
