My company proposes to hire the servies of cabs for our operations at installations under "rent a cab" category through tender. The bidder who is participating in the tender preferes not to extend the benefit of abatement on of 60% (in case he avails the cenvat credit on input service). Under such situation, whether the applicable service tax of 10.3% will come down to the extent he availed the cenvat credit for input services or not? or under such situation, the rate of service tax of 10.3% will be same or less than that ?
