Refund of RCM Paid

A supplier of nil-rated goods is facing monthly RCM payments on freight but has no GST payable. They are seeking advice on how to claim a refund or set off these RCM amounts, as they cannot offset them against any outward liability. The consensus is that while RCM paid can be claimed in GSTR 3B, a refund is not typically available in such scenarios, and the input credit cannot be refunded.
