In terms of section 2 (15) of the IGST Act, 2017, the location of a service provider is to be determined by applying the following steps sequentially:
(1) where a supply is made from a place of business for which the registration has been obtained, the location of such place of business;
(2) where a supply is made from a place other than the place of business for which registration has been obtained (a fixed establishment elsewhere), the location of such fixed establishment;
(3) where a supply is made from more than one establishment, whether the place of business or fixed establishment, the location of the establishment most directly concerned with the provision of the supply; and
(4) in absence of such places, the location of the usual place of residence of the supplier.
The location of ‘C’ is to be determined by applying the criterion from
(2), or (3), or as the case may be, (4).
