Service tax exemption on specified services limited to part of value, subject to CENVAT credit conditions. The notification exempts specified taxable services from service tax to the extent the tax exceeds the amount computed on a prescribed percentage of the amount charged, subject to conditions set for each service-predominantly the non-availment of CENVAT credit on inputs, capital goods or input services-and defines how 'amount charged' must be computed for categories such as leasing interest, bundled supplies, motorcab renting and construction services.
