Taxability of shareholding: mere holding of subsidiary shares is not a taxable supply under GST. Securities, including shares, are neither goods nor services and mere purchase, sale or holding of shares does not constitute a supply. A transaction is taxable as a service only if it meets the statutory definition of supply; classification entries describing holding company activities do not convert passive shareholding into a taxable supply. Therefore, mere holding of subsidiary shares by a parent company is not a supply of services and is not subject to GST.
