I am working in Oracle India Pvt Ltd Bangalore.I declared my investment on last date as required by the company and also declared house rent so that to get tax rebate on HRA.Now i am having one housing loan in Delhi but it just got sanctioned now,so as i have not invested anything else.Is it possible to get it declare now and get tax return.One of my friend told me that i can not declare both house rent as well as housing loan investment.So is it possible to get cancel house rent declaration and show up housing loan as investment.Can anyone tell me the whole process to follow.
