Applicability of service tax

I have a query regarding charging of service tax. my query is as below-

my client is situated in New Delhi and raise an invoice to the Head office of his client (Situated in Gurgaon)
but the goods and services are supplied at its another branch office (situated in Jammu and Kashmir).

So please guide me
Q.1. Is the Service tax is to be charge on this billing?
Q.2. Is it necessary to mention in invoice that the service is to be provide in J&K?
Q.3. Is any separate Agreement or written undertaking is required form service recipient?

Please provide the answer as soon as possible and mention any decided case law if any.
Thanks in advance.

If the service is provided in J&K area then no service tax is to be paid by the service provider as an export of service under Rule 6A of Service Tax Rules 1994, provided that the service provided is not in the course of intermediaries.

AS SERVICE TAX IS DESTINATION BASED CONSUMPTION TAX,IN THE GIVEN CASE IF SERVICES  ARE CONSUMED IN JAMMU AND KASHMIR,NO SERVICE TAX IS APPLICABLE.

IF U PROVIDE SERVICES IN JAMMU AND KASHMIR AND IF SUCH PERSON CONSUMED OUT SIDE JAMMU AND KASHMIR THEN SERVICE TAX IS APPLICABLE

Thanx Mr. Ajit Kumar Dubey andnuli swami ayyappa for your post....

As I Know Rule 8 of Place of provision of Service Rules, 2012 will apply according to which-

Place of provision of services where provider and recipient are located in taxable territory.-

Place of provision of a service, where the location of the provider of service as well as that of the recipient of service is in the taxable territory, shall be the location of the recipient of service.
