Exempted supply of services under CGST amended to revise exemptions and add postal and tour-operator carve-outs and health-care proviso. The notification amends the CGST exempt supply schedule by removing a specified qualifying phrase from multiple entries, inserting an exception excluding residential dwellings rented to registered persons, narrowing an air-travel economy-class exemption to certain northeastern airports, limiting warehousing exemptions to cereals, pulses, fruits and vegetables, adding Nil-rated ordinary postal services for lightweight envelopes, creating a partial exemption for tour-operator services to foreign tourists for the portion performed outside India (subject to a proportionate calculation and a fifty percent cap), inserting a proviso excluding high-priced non-ICU room charges from healthcare exemption, and restricting recreational training exemptions to qualifying charitable entities.
