Sir,
As per rule 3 of Place of Provision of Services Rules, 2012, the place of provision of a service shall be the location of the recipient of service. Provided that in case the location of the service receiver is not available in the ordinary course of business, the place of provision shall be the location of the provider of service.
In your case the place of provision of service is in taxable territory, that is India. the provider of service is located in non-taxable territory, that is outside India. As per Sl. No. 10 of Notification No. 30/2012-ST dated 20.6.2012 (effective from 1.7.2012)when service provider is in non -taxable territory and service receiver is in taxable territory, the service tax is payable by service receiver, that is, you.
