Service tax on foreign currency billing

Do you mean you have raised an export invoice to your foreign client. If its export of service there is no service tax levy assuming certain conditions are complied with. Or you have imported some service and want to compute service tax on reverse charge.

Thanks,

If conditions of Rule 6A of Service Tax Rule, 1994 are satisfied then it is Expoet of service and no service tax on export of service....

If it is not coverd in above then  you hav to pay full Rs 618 as service tax...
