Inverted Duty Rate Structure Refunds under Rule 89(5)
For manufacturing and processing enterprises where the GST rate on inward inputs (e.g., 18% or 28%) is higher than the rate on outward supplies (e.g., 5% or 12%), we apply the statutory maximum refund formula under Rule 89(5). We audit input tax credit ledgers, exclude non-qualifying input services and capital goods, and substantiate net ITC claims to obtain complete cash refunds without departmental deductions.
