@ ram babu.....as per my knowledge no where in the act it is return that TDS to be deducted on the whole amount of the bil raised if there is bifercation is made in the bill of material and service....
as per my practical knowledge of my articleship of 3.5 years...i learnt that if the service is seperately mentioned in the bill than TDS only attracts on the service amount......
the TDS will be deducted @ 10% if technical service and 2% if there is contract......
