Dear Minjur Dorji
Since the services are related to repair of plant and machinery, the same appears to be covered by Rule 4 of the Place of Provision Rules and hence the place where the actual service is provided will be the the location where the services are actually performed. If the repair of plant and machinery is undertaken in Bhutan, then the place of provision of service will be Bhutan and consequently there will be no service tax liability under the Finance Act, 1994. If the plant and machinery is treated as an immovable property, then also the same would get covered by Rule 5 of the PoP Rules and the place where the immovable property is located will be the place of service which in this case being Bhutan is in non-taxable territory and hence there will be no service tax liability on the repair of P&M located in Bhutan.
