As per Rule 89 of CGST Rules,
Maximum Refund Amount = [(Turnover of inverted rated supply of goods and services) x Net ITC ÷ Adjusted Total Turnover] - [Tax payable on such inverted rated supply of goods and services x (Net ITC ÷ ITC availed on inputs and input services)]
Should input tax claimed under the head of RCM be included in 'ITC availed on inputs and input services' while calculating the refund amount? [Note: RCM has been paid on inward services received]
Reverse charge credit inclusion in inverted-duty refund: RCM on inputs can be counted in ITC components, service ITC constrained. Whether credit under the reverse charge mechanism on inward supplies is includible in the Rule 89 inverted-duty refund formula turns on the formula's components: RCM-paid ITC on inputs may be included in 'ITC availed on inputs and input services,' and Net ITC should be understood as ITC attributable to inputs (including RCM on inputs). Refundability of ITC attributable to services remains constrained and generally not available under the inverted duty refund framework. (AI Summary)
