Service tax input credit eligible for rental

 Hi All,

I would request you all to clarify on below query on service tax input credits related to rental of Immovable property.

Actually  we have collected service tax from tenant. We have outsourced the securityservices of that buliding.

We have used as input service tax credit (that we paid to Security service agencies)  while remitting serice tax that we received from tenant

Whether availing this input credit is correct or not
