GST rate revisions notify classification and taxability changes for restaurant supplies, multimodal transport and digital goods. Amends Notification No.11/2017 to revise CGST treatment for restaurant and institutional food supplies, including separate inclusion of Indian Railways/IRCTC supplies, subject to the condition that input tax credit on goods and services used in supplying the service has not been taken; classifies event based supplies at exhibitions and functions separately; substitutes 'declared tariff' with value of supply in specified items; defines multimodal transportation and carves out e-books as a distinct lower-rated information supply. The amendments take effect on 27 July 2018.
