Dear Roshni,
Under the Negative List regime, the activity of agreeing to an obligation, to refrain from an act, to tolerate an act or a situation or to carry out an act has been specifically included as a declared service u/s 66E of the FA,1994. Hence, the activity of extended warranty qualify as a service.
Futher,as per Rule 3 of Place of Provision Services(General Rule) , generally the place of provision of service is the place of service receipient (unless case covered by other rules) which is India.Therefore,such service is taxable in India as per Sec 66C of FA,1994.
Further,as per Rule 2(1)(d) of Service Tax Rules,1994 read wit Notification No. 30/2012 dated June 20,2012 in case of import of service in India the service recepient located in the taxable territory is liable to pay whole of service tax under RCM.
Conclusion-Service receiver liable to pay ST on extended warranty services under RCM.
