We are local authority. Till now, we were collecting and depositing GST on our assets given on rent by us. Now, we are planning to give a contract to a agency in which agency will pay a lump sum amount to us and it will retain rent on property collected from public on assets owned by us. My query is whether GST would be applicable on lump sum payment received from agency ? If yes, whether under RCM or we should collect the same and deposit to government?
