The client derives rental income from Shed which is duly charged under income from house property. the client has provided a service of providing security for such shed for which separate gst invoice is raised stating nature of service as security charges. the client has hired security from outside to render this service to his tenant.the client has not earned any profit in this transaction. he has charged the Tenant for equal amount of expenditure incurred in this behalf to hire the security service from outside.

query - under which head this income will be taxed ? whether it is income from house property?
