1. Hello Mr. Naikar,
In the conditions described by you, it appears that you are planning to have the right to use of imported software supplied electronically and not importing a packaged software. If that be so, it would be a receipt of service covered under the ambit of IT Software Services [ Section 65(105) (zzzze) of the Finance Act].
Since the transaction will be between an Indian Entity and a foreign party, it will be a service provided from outside India,received in India. In such case the services shall be taxable in the hands of the recipient under reverse charge (Section 66A of the Finance Act) . The liability to pay service tax will be on your firm.
