In GST, when supplies are zero-rated (made without payment of tax), any unutilised input tax credit (ITC) paid on inputs or input services is refunded. However, it's important to note that ITC is not available on zero-rated goods themselves.
Wherever the supplies are Zero Rated in GST, are made without payment of tax, the taxes paid on the inputs or input services i.e. the unutilized input tax credit is refunded.
