Taxable territory determines where GST applies; services supplied outside it are not subject to GST. Taxable territory denotes the territory to which the Act applies, contrasted with non-taxable territory outside that application. 'India' for territorial scope includes the Union territory, territorial waters, continental shelf, exclusive economic zone, sea-bed, subsoil, air space, and specified installations or vessels. The charging provision limits taxation to services provided in the taxable territory; services provided in a non-taxable territory are not chargeable. The CGST enactment extends territorial application to the whole of India.
