Mr. Yogesh am afraid that u r wrong

suppose there are branches of manufacturing unit which does not manufacture but just do trading activity, the services in those units are not eligible for cenvat. even if those services are in relation to business unless they are in relation to manufacture they are not eligible

thanks for these information, but tell me how the cenvat is calculated as, XYZ manufactuing co. is paying service tax on GTA (Good transport Agency) on which he pay service tax only @ 25% of the receipt.  Can we take service tax credit in case of abatement/.

yes you can avail cenvat credit, of service tax paid on GTA , (only for Inward & upto depot / warehouse  freight,  you can't availed cenvat credit of Service tax paid on Outward freight ).

and what about service tax receivable that is paid by us for professional fee, telephone bill etc. can we take credit of these also.

yes you can avail credit of service tax on professional fees and  Telephone bills ( related to your factory)

Any Input service tax can be utilizied towards payment for excise liability.
