I know what is hire. But has the querists said that the GTA is giving services of hire?
He has just said that he his giving service of GTA. Now normally service of GTA means transportation. If the querist clarifies that it hire then it is exempt, I think both of us agreed to that. But if it is transportation then subject to the fact whether the recipient GTA is a partnership or company then again it is exempt and there I think both of us agreed to that also. But there is no blanket exemption on services to GTA to GTA.
Now you are assuming that it hire services. I am sticking to the facts as of now told by querist.
My consultation is always based on facts presented to me and not assumptions.
