Service tax on gta to gta basis

As per my view

Generally, service provider is responsible for payment of Service Tax.However, in case of Goods Transport Agency service the liability of paying Service Tax may fall on service receiver or service provider depending on the status of the receiver, as per Service Tax Rules 1994, taxable service is provided by a goods transport agency  to specified category of persons then service tax is liable to be paid by the consigner or consignee. Reverse Charge is Applicable here.

In your case the GTA is acting as a Consigner or Consignee therefor the GTA recieving the service will have to pay the service tax under Reverse Charge.
