Dear Akash
You need to refer N/N 30/2012 before applying abatement mentioned in N/N 26/2012.
The aforesaid notification states that in case the specified person(as mentioned in the notification,e.g. company, society,etc.) is the person liable to pay the freight, then that person is liable to pay under reverse charge, otherwise the liability lies on GTA only.
Lets take two examples to understand the same:
Example 1:
XYZ Ltd.(i.e. consignor) hires a GTA(company/non-company) to transfer the material to Mr. A(i.e. consignee,assuming that he is not the excise dealer) and it is written in the agreement that the freight shall be payable by Mr. A directly to GTA, then in this case no reverse charge shall apply... Since, an individual is not amongst the specified persons as listed out in the notification & Service tax liability shall be borne by GTA(if it is not specified in the mega exemption list set out in N/N 25/2012)
Example 2:
Suppose, if in the above example, if the freight is payable by XYZ Ltd. to GTA instead of Mr. A, then here reverse charge shall apply, since the body corporate is the specified person.
So, in nutshell, it doesn't matter whether the freight is inward or outward, but wat matters is who is the person liable to pay the freight.
You might have seen the consignment note(commonly called as Builty) marked as "Paid" or "To pay"
Hope now, the concept is clear to you.
