GST rate amendments expand taxable services to include renewable energy construction and pilgrimage air transport under conditions. The notification amends the Goa GST rate schedule by adding a new entry imposing a nine percent State tax on construction, engineering, installation and related technical services for setting up renewable and alternative energy systems; it also prescribes a 2.5 percent rate for non-scheduled air passenger transportation engaged by specified organisations for religious pilgrimage, conditional on non-availability of input tax credit, and inserts definitions for 'specified organisation' and 'goods carriage', while revising rates and cross-references for leasing, insurance of goods carriage, cinema admissions and related services.
