A Ltd is authorised agency for conduct of professional examination in India on behalf of University at London. All the fee including registration charges, study material charges, examination charges etc. are collected by A Ltd in India and A Ltd is free for charging any fee in India from students. However all materials such as study material, examination material, issue of certificates to qualified students etc shall be delivered to A Ltd by University and they raise invoice for the same on the basis of details of students provided by A Ltd. Now I want to know whether service tax shall be applicable on the invoices raised by A Ltd in India, if yes, under which service. Whether service tax shall also be applicable on the invoices received from University in India? Please reply with quoting notification and circular nos.
