https://www.taxtmi.com/forum/issue?id=120664 The concessional 70:30 valuation applies only where the transaction is invoiced and treated as a single composite supply of a Solar Power Generating System (SPGS). If Company Y invoices Z item-wise/HSN-wise, each item or service is taxed at its applicable GST rate and the 70:30 allocation cannot be applied; to pass the concessional rate to Z, Y must invoice Z as a single composite SPGS. Where Z procures only components or the supply is not composite, tax characterisation must be re-examined. en-us Fri, 19 Dec 2025 16:38:25 +0530 Sat, 27 Dec 2025 06:52:27 +0530 TaxTMI RSS Generator https://www.taxtmi.com/forum/issue?id=120664 The concessional 70:30 valuation applies only where the transaction is invoiced and treated as a single composite supply of a Solar Power Generating System (SPGS).
