In our company we are rendering three types of services
1 transport of goods by road
2 transport of goods by rail
3 transport of goods by air
but we do not maintain separate accounts for each of them. Service tax liability arise on transport of goods by air.
My question is can we take input credit of service tax paid on telephone service, postage, courier etc. against our service tax liability on transport of goods by air though we do not bifurcate the specifically paid for rendering service of transport of goods by air.
