taxes are payable or not

I had an agreement with sports authority of india to provide food to sports person for which the rates are fixed by licensor i.e SAI.Earlier they were giving the taxes as applicable to them for using the services of an outdoor caterer.Now they have stopped on the pretext that rate are inclusive of taxes given by licencee i.e contractor but the aggrement state that TDS, etc. will be applicable as per rule.and there is nowhere mentioned that taxes are inclusive or exclusive.Please suggest wether in a position to received taxes or not as per the agreement
