Dear Sir,
I believe the transport sector is the trickiest one when it comes to opine on service tax liability. There are lot of ifs and buts before say tax in payable or not.
What is covered under reverse charge is services provided by a GTA by way of transport of goods by road where the person liable to pay freight is the person referred under I A(ii) of Notification No. 30/2012. GTA as defined is a person providing services in relation to transport of goods by road and issues consignment notes. Now courts have reached on unanimous decision held that issue of consignment note is a non-derogable condition. if any person who provide services in relation to transportation of goods by road but does not issue consignment note cannot be treated as GTA. A person engaged in transportation of goods by road but not in the capacity of GTA, his services would be covered under entry 2(p) of the negative list. what is a consignment note is given under Rule 4B of the ST Rules. Rule 4B provides for who shall issue a consignment note. As per Rule 4B any GTA engaged in transport of Goods by Road in a goods carriage shall issue a consignment note to the recipient of services. Here you will see incongruence between definition of GTA and Rule 4B. As per definition of GTA any person who transport goods by road and issue Consignment note shall be a GTA whereas Rule 4B provides that any GTA who transport goods by road in a goods carriage shall issue consignment note to the recipient of service. Rule 4B presuppose the service provider as GTA and then cast on him the liability to issue consignment note. I believe it is just a drafting error. Further, a textual reading of Rule 4B would suggest that any GTA who provides services in relation to transport of goods by road in a goods carriage shall issue consignment notes to the recipient of service. it means under rule 4B only those GTA are liable to issue consignment note who provide services in relation to transportation of goods by road in a goods carriage, in other words nature of vehicle used in transportation may also have significant on tax liability. If the vehicle used in not a goods carriage, such GTA (my doubts regarding use of term GTA in Rule 4B already been expressed) need not to issue consignment note and thus not acting as a GTA and no tax liability if he is engaged in actual transportation of goods.
Also refer to exemption provided under 25/2012 which are specific to goods transported by GTA.
Decide your tax liability after considering above discussion.
